TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to the field of decorating
and cutting, and more particularly to a device which is operable to perform
decorating and/or cutting functions either independently or simultaneously.
Background of the Invention
In crafting and other tasks the operations of cutting and decorating
are usually performed separately. This is why there are many different types of
cutting tools and many different types of decorating tools.
Felt tip markers are able to efficiently, and for a low cost, provide
their users with an ability to decorate items and material like cloth, paper,
plastics, cardboard, wood and other porous and non-porous material. Felt tip
markers have a felt nib that is connected to an ink or decorating material
storage and transference system. The ink or decorating material is drawn from
the storage system, usually by capillary or wicking action, and moistens the nib
to allow the nib to transfer the ink or decorating material to a target material.
A major problem with markers involves the durability of the nib.
When most markers are used their nibs begin to distort due to the pressure
placed on them and the rapid reversal of forces caused by the changing
direction of the drawing and writing process. As the marker is moved up and
down, back and forth and to and fro the angle at which pressure is exerted, on
the nib, is changed and this can weaken, warp and destroy the nib. To resolve
or lessen this problem many markers are made with springs helping to absorb
the pressure of using the markers and/or a tube like casing is used to support
the nib.
Rubber stamps have the ability to transfer complex images quickly
and in a repeatable fashion. Rubber stamps have been shaped into cylinders
and when run across a material can create long repeating decorations.
Many cutting tools are available. They come in all shapes and
sizes. Some use stationary blades, some use moving blades and some use
blades that swivel to allow their cutting direction to be controlled. These
devices can be used to create precision cuts, however, precision cutting using
these devices, by its nature, is a tedious and difficult task. The task of cutting is
extremely difficult when it must be coordinated with an existing design. The
user not only needs to make sure all their cuts are done in a fashion that gives a
pleasing appearance they too must work to make sure they cut close enough to
the existing design so as to remove all surrounding non-design material while at
the same time working to avoid removing any of the design.
Present technologies do not directly address the need to
cooperatively decorate and cut either in a freeform fashion or when using a
template. A need has thus arisen for a device that allows a user to cut,
decorate and/or to cooperatively cut and decorate either independently or
simultaneously with the same device.
A need has further arisen for a cutting device with the ability to
prevent unintentional cutting.
A need has further arisen for a cutting device having a depth stop.
Summary of the Invention
A decorating and cutting device includes a housing. A cutting
blade and decorating material dispenser are disposed within the housing and
are operable to simultaneously or independently dispense decorating material
and/or cut a target material. The cutting blade is biased to prevent unintentional
operation.

Detailed Description of the Preferred Embodiments
Detailed descriptions of the preferred embodiments are provided
herein. It is to be understood, however, that the present invention may be
embodied in various forms. Therefore, specific details disclosed herein are not
to be interpreted as limiting, but rather as a basis for the claims and as a
representative basis for teaching one skilled in the art to employ the present
invention in virtually any appropriately detailed system, structure or manner.
Figure 1 shows an embodiment of the present invention that uses
a stationary blade and decorating material dispenser or nib in a pen shaped
device, which includes a cap and can be used as a normal marking device is
used. The decorating material dispenser or nib 1 wicks ink, or other decorating
material, from the decorating material storage reservoir 7, via the decorating
material feed duct 12. The nib 1 is attached to the cutting assembly 2 and also
at the cutting assembly base 5 using, for example, screws, tacks, adhesive, or
pins 11 or simply a tight fit and a shape designed to discourage any pull-away
forces. The decorating nib 1 and cutting assembly 2 are held in place by the
cushion and retaining member 6 and the nib and cutting assembly stop blocks
4. The cutting assembly base 5 is tensioned in place by force from the cushion
and retaining member 6. The cushion and retaining member 6 allows the
cutting assembly 2 and nib 1 to be biased in a stationary position and also to
give, flex and move slightly, when force is exerted during use. This will prolong
blade and nib life and also protect them from shock. Member 6 also gives the
device a softer feel and makes it easier to accommodate rough surfaces. The
cushion and retaining member 6 also operates with a valve system. One
embodiment has the valve attached to and working with the nib and cutter
assembly base 5.
The decorating material reservoir 7 can simple be an empty
reservoir or it can be filled with a material that is conducive to storing the
decorating materials as anyone skilled in the art will know. The closing cap 8
keeps the decorating material sealed inside the main case 15.
Decorating material as used herein is any type of material that can
be applied to a target material or surface for any useful purpose. Decorating
material includes, for example, but is not limited to ink, dye, glue, lacquer,
etching solution, oil, stain, colored wax, glitter and glue, colored glue, clear coat
or any other material that might have some useful benefits. A target material
includes, for example, paper, cloth, leather, cardboard and the like, or any other
material that might receive some useful benefits.
Other features of the device of Fig. 1 include a finger grip 9
designed to make the device comfortable to use. A template trace edge 3
designed to make it easy to use the device with a template. A color indicator 10
designed to show the color, type and surface finish, and other characteristics, of
the decorating material and or blade.
A user uses the device of Figure 1 like a regular pen type marking
device and instead of simply marking they mark and cut simultaneously.
Figure 2 shows a side view of the cutting assembly with cutting
edge 2, base 5, hole 16 for attachment pin 11 and decorating material duct 12.
Figure 3 shows the nib 1 with its hole 16 for attachment pin 11 and
opening through its center to accommodate the cutting assembly.
Figure 4 shows a side view of an additional embodiment of the
invention using a rotating cutter assembly, rotating decorating assembly with
decorating material supply pad. The device uses a rotating blade, with flat or
shaped cutting edge, in cooperation with a rotating decorating device.
This embodiment stores the decorating material in the decorating
material storage vessel 35 and feeds it to the decorating material supply pad 32
via the decorating material supply 34 that can use capillary, wicking or any other
suitable transmission action.
A user uses the device by holding the handle 29 and pushing the
decorating disk 20 and cutting disk 21 on a target object and then applying force
in the direction they wish to cut and decorate.
The spring 28 gives the device a softer feel and more control over
the pressure that is applied.
Figure 5 shows a bottom view of the device shown in Figure 4.
Screw head 23 acts as one end of the shaft that holds the decorating disk 20,
guide shaft 26, spacing washer 25, wave spring 22 and cutting disk 21
assembly. The other end is closed by a locking nut 24 that is used to close the
end of the shaft and also acts as a tensioning adjustment. This embodiment
shows a flat round blade that will produce a straight edge cut. It is important to
note that a shaped blade edge is used, with or without spacers, to make cuts of
varying shapes at varying distances from the decoration. The device is
assembled with the guide shaft 26, and other components, arranged differently
to create different effects and different feels when being used. As one example,
the device is assembled with the shaft on the right side of the cutting and
decorating disks to allow easier use by a left handed person. Another example
is to assemble a shaped cutting disk on the left side of the guide shaft 26 with a
2mm sized spacer 37 and the cutting disk on the right side of the guide shaft 26
with a 3mm sized spacer 37. This would allow creation of a shaped cut edge
with the design being made 5mm plus the size of the guide shaft away. Another
configuration includes using a nut, acting as a spacer, with the blade and guide
shaft held securely and a decorating disk held loosely on the other side. This
configuration would make consistent cuts with inconsistent and random designs
that might be very appealing when interested in creating one of a kind, natural
patters or security bands that need to be difficult to duplicate.
Figure 6 shows a cut edge with a design on the right of it, as one
might see, created by a device as shown in Figure 4.
Figure 7 shows an embodiment of the device that uses multiple
decorating wheels 36 and a single cutter 38. In this embodiment two different
decorating material supply pads 32 are used, one to supply each decorating
wheel 36, but each using different decorating materials. This allows the device
to color each side of the cut with different, or same, material. In this
configuration the main cutting blade 38 is sandwiched between two legs of a
guide shaft 26. The main cutting wheel 38 shown is a perforation wheel, as
shown by the diagonal lines, so instead of making a full cut wheel 38 makes a
perforation that can be later hand torn to the shape with the decoration on each
side. Cutting wheel 38 can be interchanged to create different effects and
different types of cuts or other operations like embossing, engraving, punching
or any other desirable outcome. The screw head 23 maintains the assemblies
on shaft 26. The wave washer 22 allows the nut and tension adjustment 24 to
remove slack from the assembly, which allows it to turn as freely or as tightly as
the material being cut and decorated and the user needs and wants it to. The
support screw 27 is sized to accept at least one cutting wheel 38 and at least
one decorating wheel 36. One or more cutting wheels 38 and one or more
decorating wheels 36 and one or more sized spacers are assembled in varying
configurations that perform various tasks of decorating and cutting. This allows
these devices to make cut and decorated edges and also strips cut on both
sides with decorations down the center. It can create one to many strips each
with cut edges and or perforations and designs all at the same time. The
decorating material supply 34 draws decorating material from the decorating
material storage vessel 35. If desired the decorating material supply 34 can be
discarded and instead the decorating material supply pad 32 can store the
decorating material. Replacing the decorating material supply pad 32 will
replenish the decorating material supply. This configuration also allows for
quick decorating material changes.
Figure 8 shows a target material, like a sheet of paper or cloth,
with edges created by the device of Figure 7. The single cut is surrounded by
two decorated edges. The decoration is almost touching the cut edge because
a small spacer 37 is used to separate the blade 38 from the decorating wheel
36. The cut edges shown in Figure 8 are made with a straight flat cutting wheel
like the one shown in Figure 5. The decorated perforation 39 is created from a
device configured with a perforation blade and two decorating wheels.
Figure 9 shows an embodiment of the present invention that uses
a swiveling blade nib assembly to allow easy creation of curved cuts and
designs. The cutting blade 41 is attached to the decorating nib 40 and the
swivel mount 55 to create an assemble that can rotate about the cutting edge of
the blade. The blade nib end support 43 interfaces with the decorating material
valve 54 that is attached to the blade nib support spring 45. When pressure is
applied to the blade 41 and nib 40 the decorating material valve 54 opens to
provide decorating material to the nib 40. Decorating material valves are
generally known to those skilled in the art. Valve 54 includes a rounded and cut
through piece of material that will keep the decorating material in the decorating
material storage area 44 until pressure is applied then it will leak, at the seams
of the cuts thus supplying decorating material. The decorating material that is
released is drawn by the decorating material feed 48 and then through the
decorating material exit opening 49 to the nib. Wicking or capillary action can
draw the decorating material to the tip of the nib and the nib will draw the
material to its end. The rounded top of the decorating material valve acts as a
bearing for the blade nib end support 43 and helps lower friction to increase
ease of swivel action. The blade and nib assembly is held in place by the blade
nib retaining lock 42. The blade nib retaining lock 42 is moveable far enough
away from the blade nib assemble to allow it to be removed and replaced with a
new or different blade nib assemble. This will allow a user to change the blade
and nib either to replace a well-worn blade and/or nib or to use one with
different characteristics like thickness or shape of nib or size or type of cutter.
Figure 10 shows the blade with its end support 43, decorating
material feed 48, decorating material exit opening 49, blade nib attachment
means 51 and cutting edge 50. The use of each of these is outlined in the
embodiment above.
Figures 11 a. and 11 b. show the nib 40 with swivel mounts 55 and
duct 52 for blade. Swivel mount 55 is used to attach the nib and blade in a
manner that will allow them to be firmly pressed to the target material yet still
swivel to cut and decorate curves.
Figures 12a. and 12b. show the blade nib retaining lock 42 details.
It has a fingernail pull recess 53, and entry slot and a cylindrical cutout in the
center that supports and snaps onto the center swivel mount attached to the
blade nib assembly.
Figures 13a. and 13b. show the blade nib support spring 45. This
is made of a springy material that also acts as a barrier holding in the
decorating material in the decorating material storage area 44. When the blade
nib support spring 45 is pressed, by the force of using the blade and nib, the
slits in the decorating material valve open enough to allow decorating material
to pass from storage to the decorating material feed 48.
Figures 14a. - 14d. show how the blade and nib will swivel in the
direction of the desired cutting and decorating as the user uses the device.
Figure 15 shows an attachment that allows a swivel cutting and
decorating device, like the one described above in Figure 9, to be more easily
controlled. A swivel cutting and/or decorating device is attached to the device
as shown in Figure 20. The user inserts the pen, cutting implement, or a cutting
and decorating device into the pen and cutter opening 63 and screws it into the
threaded pen attachment location 69. This attachment can also be made by
friction, a pin or other forms of attachment. Now the user can hold the edges of
the device, with one to many, fingers on the finger grip 61. The user can see
the target material and the cutting and decorating tool through the magnifying
lens 62. By pushing down on the finger grip 61 the silicon like see through
spring 64, or a real spring, compresses allowing the blade and/or nib to contact
the target material. Moving the device with the top element pressed down will
cause the decoration and/or cutting to take place at the point the decorating
and/or cutting assembly contacts the target material as seen through the lens.
Rollers 66 assist the device moving across the target material and also keep the
blade and nib from contacting the target material until engaged to do so.
Figure 16 shows the top assembly 60 of the device. Its center
opening 63 firmly holds the decorating and cutting device, which can have
screw threads that mesh with those inside the center opening 63. The
assembly threaded opening 71 allows the top assembly 60 to be attached to the
bottom assembly 65 via a screw passed from the bottom assembly 65 through
the spring 64 and finally screwing into the top assembly 60.
Figure 17 shows one embodiment of a spring 64 that uses a piece
of compressible clear material, such as, for example, gel or silicon, with
openings molded or cut into it to allow it to match the openings in the top and
bottom assemblies. The spring 64 acts as a spring and also allows the target
material to be more viewable.
Figure 18 is the bottom assembly 65. The pass through 73 allows
the pen to freely move up and down as the pressure on the top assembly 60
dictates it should. It also has a stop on it to keep the pen and or cutting device
from slipping out the bottom of the entire device. Roller snap-in recesses 72
are designed to allow a ball bearing type roller to be snapped in place and then
to freely turn to assist in rolling the device across a target material. Assembly
screw recesses 68 allow a screw to connect the top and bottom assemblies,
along with their integrated components, together.
Figure 19 is a top view showing a device and one possible layout
of rollers 66 and assembly screw recesses 68.
Figure 20 is an orthogonal view of one embodiment of the device
showing the pen and or cutting device in the center.
The shape of the entire device can be any shape. A circle was
selected as an example and should not be considered limiting. Hand
conforming tear drop shapes, square, rectangle, oval, shapes of company logos
and any other shape that would be desirable could be used.
Figures 21. and 24. show a modified blade roller assembly that
uses the roller to distribute decorating material while cutting or uses the roller
simply to assist in cutting or uses the roller to distribute a material or solution
that performs a task or assists in cutting without decorating or applying any
material. This embodiment of the invention uses a pull cutting blade 81 with a
roller 80 set ahead of it. The roller 80 scores a path in front of the blade 81
assisting the blade in cutting along a specific path. The roller 80 also allows a
user to make more accurate and intricate turns and curves. In addition to other
benefits the roller 80 provides a cushion protecting the cutting blade and or
limits the cutter's depth protecting beneath the material by pushing the cutter
above the material. Ball bearings 82 are used to support the device in a
manner that allows it to swivel freely.
Figures 22. and 25. show a modified blade roller assembly that
uses the roller to distribute decorating material while cutting or uses the roller
simply to assist in cutting or uses the roller to distribute a material or solution
that performs a task or assists in cutting without decorating or applying any
material. This embodiment of the invention uses a push cutting blade 81 with a
roller 80 set behind it. The roller 80 assists the blade 81 in rolling across the
target material. The roller 80 also allows a user to make more accurate and
intricate turns and curves. In addition to other benefits the roller 80 also
provides a cushion protecting the cutting blade and limits the cutter's depth
protecting beneath the material by maintaining the cutter above the material. A
low resistance sleeve 83 is used to hold the shaft in place in a manner that
allows it to swivel freely.
Figures 23. and 26. show a modified blade roller assembly that
uses the roller to distribute decorating material while cutting or use the roller
simply to assist in cutting or use the roller to distribute a material or solution that
performs a task or assists in cutting without decorating or applying any material.
This embodiment of the invention uses a centrally located cutting blade 81 with,
more than one, roller 80 set near it. The rollers 80 assist the blade 81 in rolling
across the target material. The rollers 80 also allow a user to make more
accurate and intricate turns, cuts and curves. In addition to other benefits the
rollers 80 also provide a cushion protecting the cutting blade and limiting the
cutter's depth protecting beneath the material by maintaining the cutter above
the material. A low resistance sleeve 84 shaped and acting like a spring is used
to hold the shaft in place in a manner that allows it to swivel freely. The ball end
and concave low resistance mount means 85 allows the device to be attached
to a receptacle that will hold it firmly in place and allow it to swivel.
In the embodiments shown in Figures 21, 22, 23, 24, 25 and 26 it
is important to note that the blade can be made to be higher or lower than the
rollers and/or at different angles in relation to each other to provide different
advantages when cutting different materials. Separate adjustments are added
to allow manual adjustment to be made allowing the user to adjust the
orientation and/or height of the roller, or rollers, in reference to the blade or
blades. These devices may be made, for example, with one or more blades
and one or more rollers in any orientation or configuration that is found to be
advantageous and/or as the needs of the task require or would be assisted by.
Figures 27, 28 and 29 show a blade and nib configuration that
allows the user to set the tool so it will exhibit different characteristics. By
moving the blade and or nib a user can change the way the tool works and acts.
For example if the user moves the nib all the way out, toward the target
material, and then moves the blade toward the inside of the device, further
away from the target material, the user could set the blade so it only scores,
instead of cuts through, the target material while it is decorating the target
material. If the user moves the blade all the way into the device the device will
still decorate the target material but will not score, mark or cut it. By moving the
nib slightly into the device and the blade all the way out the user could cut the
target material and only lightly mark it or move it further in and not mark it at all.
Different combinations of relationships between the blade and nib and their
performance on different target material can produce different useful results.
This makes this tool quite useful and able to adapt to different target material
and to perform many useful functions.
The following descriptions show some of the many ways the
relationship between the protrusion of the blade and nib from or into the device
and the relationship between the blade and nib can be used to create some of
the many combinations of features this device can perform. These drawings
are not meant to be limiting but simply meant to show examples of several of
the almost infinite possible combinations of the blade, nib and device
relationship.
Figure 27 shows the blade 100 and nib 101 in a position that
allows the user to cut and decorate simultaneously. The handles 102 allow the
user to engage or disengage the blade and/or nib. A spring 103 helps to
tension the blade and nib and the incremental movement position fins 106 work
with ridges inside the case to cause the blade and nib to click as they are
moved and also biases them to stay in the position they are set in. By placing
more ridges inside the case the user has more ability to determine the
incremental distance in the relationship between the blade and the nib and the
blade and nib's protrusion or insertion into the device. The fin 106 works similar
to a locking blade in a cable tie and the ridges are similar to the ridges in the
cable tie's main strip. In a cable tie the locking blade and ridges allow for
movement in only one direction but in this device the movement is allowed in
both directions.
Figure 28 shows the blade 100 and nib 101 in a position that
allows the user to cut without decorating. The handles 102 allow the user to
engage or disengage the blade and/or nib. Its other features are similar to the
description of Figure 27 above.
Figure 29 shows the blade 100 and nib 101 in a position that
allows the user to decorate without cutting. The handles 102 allow the user to
engage or disengage the blade and/or nib. Its other features are similar to the
description of Figure 27 above.
The user, because of the almost infinite free movement between
the blade 100 and nib 101, can select any position for the blade 100 and nib
101. This allows the user to take advantage of the different possibilities created
by changing the orientation of the blade to the nib, the blade to the device, the
nib to the blade, the nib to the device and the combination of the blade and nib's
orientation to the device. Moving the blade and nib all the way into the device
closes the device for storage, transportation, and protects the blade and nib and
items they come in contact with.
Figure 30 shows a side view of the blade 100 assembly.
Figure 31 shows a side view of the nib 101 assembly.
Figure 32 shows a top view of the blade 100 assembly with a
protruding alignment pin to hold the blade and nib in alignment.
Figure 33 shows the top view of the nib 101 assembly.
Figures 34a., 34b. and 34c. show three top views of the device
with its blade and nib in three of their many possible combinations. Figure 34a.
shows how the handles 102 would look, in this embodiment, when they are set
for cut and decorate. Figure 34b. shows how the handles would look, in this
embodiment, when they are set for decorate only. Figure 34c. shows how the
handles would look, in this embodiment, when they are set for cut only.
The blade and nib can be moved in any combination and to orient
themselves to each other and the device itself in any manner. Indicator indicia
and or pronounced internal ridges and or internal or external stops can be
added to the device to allow easy reference for setting the tool. If, for example,
we find an optimal setting for a target material, like 1/8 inch thick leather, to be
with the blade as far out as possible and the nib to be 1/16 inch further away,
toward the device, causing the blade to protrude 1/16 inch beyond the nib. It
could be noted on the device, in a visual, auditory, tactile or combination of any
or all three methods of indication of this optimal position for the blade and the
nib. This allows the user to set the device quickly for the task or material at
hand.
Figure 35 shows a bottom view of an embodiment of a multi-edged
decorating and cutting device with three non-cutting colored nibs 121,
122, 123, one colored nib 124 with internal cutter 129, a four faced blade
assembly 133 with four cutting edges 125, 126, 127, 128 and a case 120
holding everything. A user can use one cutter with two nibs simultaneously.
For example if one orients the first cutting edge 125 directly toward the target
material they will also be orienting the first color nib 121 and the second color
nib 122 so that when the device is being used the end result will be a cutter with
the decorating material from nib 121 on the one side of the cut and decorating
material from nib 122 on the other side of the cut with the cut, made by cutting
edge 125 toward the center. The user could also orient one of the non-internal
cutting nibs 121, 122, 123 toward the target material. This will allow them to
apply decorating material without cutting. When the nib 124 with the internal
cutter 129 is used it will apply decorating material from itself around the internal
cutting blade 129. The nib is used with cutting blades 127 and 128 and
associated nibs 123 and 121 respectively to produce results similar to the other
nib and without using the internal cutter. This nib is also used with its internal
cutter 129 by itself.
Figure 36 shows a bottom view of the four faced blade assembly
133.
Figure 37 shows a bottom view of the second color nib 122.
Figure 38 shows a bottom view of an embodiment with four nibs
that contain internal cutters 129. A spacer 130 is used to separate each nib,
and thus each cutter, a specific distance. This keeps the nib far enough away
to avoid contamination from one nib to another. This device can be used to
create cuts on which both of its edges have applied the same decorating
material or material to perform a specific task. The internal cutter will cut while
the nib applies the decorating material around the cut. This device contains
four different decorating materials or other types of materials. And the user
selects which cutter and material they are applying by rotating the case, in
reference to whatever is holding it be it their hand or some other holding device,
to orient the correct nib and cutter for the task toward the target material.
Figure 39 shows a side view of the device shown in Figure 38.
This view shows how the internal blades 129 are attached to the nibs 124 via a
blade to nib attachment means 137. Also this device uses a sized
spacer/separator 130 in place of a four faced blade assembly 133, storage
vessels 132 and an end cap 136. This embodiment uses the spacer/separator
130 or a four faced blade assembly 133. The springy connector supporting
blade and spacer/separator 135 attaches the nibs 124 and internal cutters 129
assembly to the device in a manner that allows the blades and nibs to transfer
pressure, applied during use, to compress the springy connector supporting
blade and spacer/separator 135 to make the device feel responsive during use
and to protect the blades and nibs. The decorating material storage separator
131 keeps the materials that feed each individual nib separate to avoid
contamination from one decorating material storage vessel 132 to the other.
Figures 40a. and 40b. show a side and bottom view of a nib
without an internal cutter.
Figures 41a. and 41b. show a side and top view of a four faced
blade assembly. A sized spacer/separator would look similar to this with its fins
protruding less than the ones shown for the blades because the fins would not
need to contact the target material.
Figures 42a. and 42b. show a bottom and side view of a nib 124
with internal cutter 129 held together by a blade to nib attachment means 137
and the friction made by the assembly itself.
Figure 43 shows a cutting tool 300, a nib 301 and a safety zone
305. The safety zone 305 gives the device the ability to require an
advantageous minimum pressure to be placed on the nib 301 before the nib
301 will allow the cutting tool to engage a target material. The cutting tool is set
such that it has cutting depth stops and pushdowns that limit the cutting
possible and set a working maximum cutting depth. By varying characteristics of
the nib 301 including, for example, its composition, material, structure, design,
density, rigidity and shape along with the distance, and design, of the cutting
tool one can control how and when the nib 301 will allow the cutting tool to
contact a target material. The safety zone 305 requires a set minimum pressure
to be applied before the cutting tool is able to engage a target material. The
safety zone 305 controls how and by whom the device can be used. For
example if a device is made with a safety zone 305 that needs a great deal of
pressure to allow the cutting tool to engage the device will be safer to use and
will require more pressure to engage the cutting tool. This makes it difficult for
children to accidentally engage the cutting tool. By making a safety zone 305
that requires little pressure to engage the cutting tool the device will more easily
allow the cutting tool to engage the target material. This will allow professionals
to use the cutting tool with less fatigue. Various embodiments and
configurations will take advantage of the possible safety zone 305 sizes and
designs.
The safety zone 305 shown in this embodiment is made such that
the nib 301 is denser and more rigid than the average person's skin and body.
Nib 301 is designed to be more rigid and denser than the human body because
when combined with a cutting tool, set sufficiently back to eliminate its ability to
touch the target until the nib 301 compression pressure is reached, a device is
created that cannot cut the human body. When the device is applied to the
human body, so as to attempt to cut the body or by accident, the pressure
applied to the device causes the human body to compress and does not allow
the cutting tool to engage. Because the human body is less dense and rigid the
pressure applied to the nib 301 causes the body to compress and the nib 301 to
maintain its shape. The same nib 301 when applied to a target material on a
table or desk will absorb the pressure and allow the cutting tool to engage
because the nib 301 is less dense and less rigid than the table or desk. In this
embodiment the nib 301 will keep its shape, when applied to a less dense
surface, allowing flesh to be biased away from the cutting tool.
When this embodiment is used with a target material on a solid
surface that is denser than the nib 301, like a piece of cloth or paper on a
cutting mat or table, the nib 301 will compress and allow the cutting tool to
engage the target surface. The cutting tool will engage a target surface and cut
it but it is biased against cutting less dense material like that of the human body.
The safety zone 305 is an area that allows the device to be used, without
engaging the cutting tool, until a certain set of circumstances are met. These
circumstances are application specific allowing many embodiments of this
device to be created simply by varying the design, construction and orientation
of the nib and cutting tool. Other safety zone 305 designs will be made in such a
manner as to allow acceptable characteristics for specific applications and
needs.
Another example of the benefit of selecting the nib 301 density
and rigidity in combination with the location of the cutting tool 300 uses a very
soft nib 301 and a cutting tool protruding from the device. This configuration
allows a person to make deep cuts and precisely locate the cutting tool while
simultaneously applying a great deal of decorating material. The soft nib will
ensure contact with the target material while allowing the cutting tool to cut
deeply into the target material. This embodiment would be very useful for
creatina designs in leather and other such materials.
Another embodiment of the invention uses the configuration of
Fig. 43 with a nib 301 that does not wick any material. In this embodiment a
safer cutting tool is created. Because the benefits of the nib 301, the benefits of
protecting the target materials and the cutting tool, are taken advantage yet the
cutting tool is able to engage target material when the safety zone allows it to.
This embodiment creates a much safer cutting tool that is easy to use.
Embodiments of this device will have a colored nib or will have designs or
indicia on the nib to show where the cutting tool is and to help a user orient it.
The description of the nib 301 as being denser and more rigid is
designed to convey the concept of a nib 301 that needs specific characteristics
to be met before it will yield and or move such that it allows the cutting tool 300
to engage target material. There are many ways this can be done and the
above descriptions and embodiments are simply designed to be representative
of some of the ways. The composition, design, structure, shape, orientation and
location of the nib and the composition, design, structure, shape, orientation
and location of cutting tool, themselves and with respect to each other, will yield
many useable embodiments of this invention.
Figure 44 shows the cutting tool of Fig. 43. Cut stop 304 is made
to be thick and unable to cut. This is done to require the tool to be at an
appropriate angle before it will allow the cutting tool's cutting edge 302 to
engage a target material. By varying the shape of the cut stop 304 other
embodiments are created that give different advantages to their users. A larger
radius rounded cut stop 304 will cause the tool to require a lower angle of attack
to begin cutting and a smaller radius rounded cut stop will allow the tool to be
used in a more upright position. The position and location of this cut stop 304
makes this embodiment of the cutting tool biased against cutting with a stabbing
action. During a stabbing action the rounded cut stop 304 will be the portion of
the cutting tool that contacts the target material. Because the cut stop 304 is
thick and rounded and without a point it is not able to easily cut thus making the
tool safer.
Flat depth stop and guide 303 leads into the cutting tools cutting
edge 302 and stops the cutting edge 302 from penetrating below a specific
depth set by the height of the depth stop and guide's 303 face in relation to the
cutting edge 302. The depth stop and guide 303 also provide tactile feel to the
user and helps orient the cutting edge. Users, when they apply enough
pressure to the cutting tool to move the blade far enough to allow the depth stop
to contact the target material, will feel it bottom out when the depth stop and
guide 303 is pressed against the target material. This embodiment uses a depth
stop and guide 303 with a filleted lead in to the cutting edge 302 and a shaped
point intersecting with the bottom of the cutting edge. The depth stop and guide
303, in other embodiments, will have square, filleted or shaped edges on one or
more sides.
Depth stop 306 limits the depth the cutting tool will cut biasing it
against cutting deeper than desired. Cutting edge 302 in this embodiment is
ground on two sides and in other embodiments it will be ground on at least one.
In embodiments using a single ground edge the depth stop 306 will cause the
cutting edge to be more particular about how and what it will cut. It will make a
safer tool that will only cut when it is pressed to target material in a certain
manner. This embodiment uses a dual ground cutting edge and will have the
depth stop 306 on each side of the cutting edge allowing it to cut with greater
ease and to be less particular. Both embodiments have advantages when used
for certain purposes under certain circumstances.
Figure 45 is a front view of the tool of Fig. 43 having a nib 301 in
two halves. Other embodiments use nibs that can be a single piece. And other
embodiments use multi-part nibs that have top, bottom, left and right sides.
Each of the nibs can, but does not have to, wick decorating or beneficial
material.
Figure 46 shows a side view of an embodiment of the present
invention that uses a spring 324 biased cutting tool shield 320. The cutting tool
shield 320 rides on the cutting tool shield guides 321, supporting the shield on
at least one side, and meshing with the cutting tool shield guide surfaces 325.
Case 323 of this embodiment is designed to store decorating material and can
also operate without it. When the required minimum pressure is applied to nib
301 it compresses and allows pressure to be applied to the cutting tool shield
320. The cutting tool 300 cannot engage the target material until enough
pressure is applied to compress the nib 301 and spring 324. When enough
pressure is applied nib 301 and the cutting tool shield 320 move enough to
allow the cutting tool 300 to engage a target material. The cutting tool shield
320 is the primary safety feature and the safety zone portion of the nib is the
secondary. This allows the device to be safe to use and to maintain a specific
required minimum pressure, as set by the spring 324, that must be applied
before the cutting tool will be able to engage the target material.
Figure 47 shows a side view of the cutting tool 300 and the cutting
tool shield 320 of Fig. 46 and how they are assembled.
Figure 48 is a front view of the cutting tool shield 320 of Fig. 46.
Cutting tool shield guide surfaces 325 fit the cutting tool closely and orient the
cutting tool shield 320 to the cutting tool. The cutting tool shield guide surfaces
325, in this embodiment, are set centrally within the cutting tool shield 320 as is
seen in this front view. Other embodiments use different offsets to create cutting
tool shields that take advantage of the extra face surface on one of the sides of
the cutting tool. Cutting tool shield face 326 in this embodiment is made to be
about 4 times greater than the thickness of the cutting tool. This provides a solid
surface that can be run over the target material when the cutting tool is not
engaged. It also acts as a spreader that flattens target materials about to be cut
making cutting easier. Other embodiments use cutting tool shield faces of
different sizes and shapes to gain different advantages based on the specific
needs of the task at hand.
Fig. 49 is a front view of the tool 300 shown in Fig. 47.
Fig. 50 is a side view of an embodiment of the present invention
that uses a spring to bias a cutting tool 342 into a non-cutting position. Nib 346
is held in place by nib holder 344. Case 347 has a decorating or beneficial
material storage vessel 348 that when filled allows the device to cut and
decorate and when left empty allows the device to cut only. Case retaining
surface 343 mates with the nib holder retaining surface 344 and keeps the two
parts together in a manner that allows the case 347 to be pushed so that it
causes the nib 346 and/or cutting tool 342 to engage a target material. The nib
346 will easily engage a target material. To cause the nib 346 and the cutting
tool 342 to engage a target material enough pressure must be applied to
compress the spring 345. This causes the cutting tool 342 to move to a position
that allows it to engage a target material. In different embodiments different nibs
with different density, rigidity, structure and shape are designed to work in
cooperation with different springs, the orientation of the two, and distance of the
cutting tool to the target material. By adjusting these parameters devices of
different attitudes are created. The spring 345 helps to control the minimum
required pressure to allow the cutting tool 342 to be in a position to engage at
target material.
This embodiment allows the user to select a unique decorate only
mode. The user can also easily operate the device as a decorate and cut
device. By holding the decorate only finger grip 353 the user can easily and
comfortably engage only the nib 346 in the same manner one uses a standard
marking device. When holding the decorate only finger grip 353 it is not possible
for the user to engage the cutting tool because the spring 345 is biasing it away
from the target material. The user can apply as much pressure as they wish
without the possibility of engaging the cutting tool. When the user places
pressure on the nib holder 351 using the decorate only finger grip 353 they are
pushing only the nib 346 to the target material and not the cutting tool 342.
When the user places pressure on the case 347 at the decorate
and cut finger grip 352 the user engages the nib 346 and also the nib 346 and
cutting tool 342 by simply applying the appropriate pressure.
Because the cutting tool 342 is inserted into the handle 347 it
cannot be engaged during use unless the user is operating the device while
holding the decorate and cut finger grip 352 of the case 347.
Figure 51 shows the tool of Fig. 50 with its spring 345
compressed. This positions the nib 346 and cutting tool 342 in a position ready
to engage a target material. Other embodiments allow the user to set the device
to free-movement like in this embodiment and also have a locked spring mode
in which the device will operate with the spring set at uncompressed, fully
compressed or partially compressed. These embodiments give the user access
to different features and benefits of different modes.
Fig. 52 shows a side view of the tool of Fig. 50. This nib is made
in two parts that sit on each side of the cutting tool 342 and is long enough to
reach the decorating and or beneficial material storage container 348. Nib
support shoulder 341 meshes with the nib stop 349 and keeps the nib from
being pushed into the device by the pressure applied during use.
Nib holder 351 with nib stop 349 keeps nib 346 from being pushed
into the case when pressure is applied. Decorate only finger grip 353 allows a
user to easily operate this embodiment in a decorate only mode. The nib holder
retaining surface 344 is shaped to allow the nib holder 351 to move freely and
also to keep an airtight seal protecting the nib 346 from drying out. Other
embodiments use o-rings, gaskets or other devices to keep the airtight seal.
Cutting tool 342 is inserted into case 347. The decorating and
beneficial material storage container 348 is made of felt and wrapped in
cellophane 350. The decorating and beneficial material storage container 348 is
a common practice in many marking devices of today. Other embodiments use
liquid, gel, wax, glue, chalk, dye, water, acid, etching solution, ink, food coloring
or other types of decorating or advantageous material. Retaining surface 343 is
shaped to hold the nib holder in such a manner as to allow it to freely slide so
the cutting tool 342 can engage the target material while it also creates an
airtight seal to protect the nib from drying out.
Figs. 53, 54, and 55 show an embodiment of the present invention
that uses a lock that cooperates with a button to make a device that will operate
as a decorating device and only decorate until specifically engaged as a
decorating and cutting device.
Fig. 53 is a side view of an embodiment of the present invention
that uses a cutting tool lock 360 biased in the locking position by spring 366 to
hold a cutting tool and cutting tool activation button 361 in a locked position.
This embodiment works as follows. A user pulls back the cutting tool lock 360
which compresses spring 366. This allows the user to press the cutting tool
activation button 361. As the cutting tool activation button 361 moves down its
cutting tool activating surface 363 pushes the cutting tool 367 forward. The
cutting tool 367 is pushed relative to the pressure applied to the cutting tool
activation button 361. Spring 364 is used to bias the cutting tool activation
button 361 to the non-engaged position. Nib 362 has a safety zone 365
designed to bias the device to be used in a safe manner and to protect surfaces
and the cutting tool 367 even when it is engaged. This embodiment uses a dual-side
ground dual-cutting edge 371 that allows it to cut at many angles and using
push, pull and poke cuts. Spring 370 bias cutting tool 367 to a non-cutting
position.
The cutting tool 367 depth stop and guide orients the cutting tool
centrally in the nib 362 and it also acts as a depth stop. The flat surface of the
cutting tool 367 depth stop and guide also keeps the cutting tool centrally
located inside the nib 362.
Fig. 54 shows a side view of the tool of Fig. 53 with the cutting tool
lock 360 disengaged and cutting tool activation button 361 fully engaged and
the cutting tool 367 ready to engage a target material. In this embodiment the
nib 362 has been designed to have a safety zone 365 that keeps the cutting tool
away from all surfaces until it is intentionally engaged and more than the
required minimum pressure is applied to the invention. In this embodiment the
nib 362 is designed to wick material. In other embodiments the nib 362 is simply
used to protect surfaces from the cutting tool by filling the safety zone 365 with
a material of a specific density, rigidity, design and composition.
Fig. 55 shows a top view of the tool of Fig. 53. Cutting tool 367
guide and stop is designed to limit the depth of cut and to also provide enough
surface to allow the cutting tool 367 to self-center and to move, in the nib 362, in
a precise and repeatable manner. In this embodiment the cutting tool will
always self-orient to a position that is comfortably aligned with the activation
button 361. Other embodiments have cutting tools that rotate and still others will
have cutting tools that swivel. These additional embodiments also take
advantage of a selectively engage-able cutting tool using an activation button
and an optional locking mechanism.
Fig. 56 shows a side view of the nib 362 with a safety zone 365,
an area that is used as a point where wicking can start 371, in embodiments
that require wicking, and a shoulder 370 designed to keep the nib 362 from
being pushed into the case when pressure is applied.
Fig. 57 is a side view of the cutting tool activation button 361 with
spring 364 to bias the assembly to a non-engaged position. Cutting tool
activating surface 363 works as an inclined plane to move the cutting tool to an
engaged position and against spring 370.
Fig. 58 is a side view of the cutting tool lock 360 with spring 366
and locking member 368. The locking member 368 is used to stop the cutting
tool activation button 361 from engaging the cutting tool until the user actually
wishes to engaged the cutting tool. This protects the cutting tool and other
surfaces from being unintentionally cut, scratched, poked or damaged.
Fig. 59 shows a side view of the cutting tool 367 with activation
surface 369 cutting tool stop and glide shoulder and multi-direction cutting tool
371 that can be used to cut on at least one side.
Fig. 60 shows a side view of an embodiment of the present
invention with a cutting tool 381 having a cutting edge and cutting point 382 set
toward the top of the nib 380. This allows a person to cut and decorate leaving
only a small amount of decorating material where the cut begins. It also has an
additional advantage of requiring a higher angle of attack to engage the cutting
tool which means a person can use the marker, more easily, as a standard
marker. The user will not be able to cut or engage target material, with the
cutting tool, unless they raise the use angle of the cutting tool 381 and nib 380
so that the cutting tool point 382 is at an angle that allows it to contact the target
material. This embodiment will be more easily used as a marker only and will
require pressure to be exerted, at a higher angle, before it will cut. This
embodiment uses a stationary cutting tool. Other embodiments use rotating and
or swiveling cutting tools.
Fig. 61 is a side view of a cutting tool 386 with a centrally biased
cutting edge 383 and a nib 380 with safety zone 385. This allows a user to cut
with the device using one of two cutting tool edges and at a variety of angles.
When one side becomes dull the other side can be used. This extends the
devices useful life. The location of the cutting edge and cutting point 383 toward
the center of the nib 380 creates a device that decorates and cuts when used at
a moderate and fairly normal writing angle and also at a higher angle and also
with a pushing motion that will pierce the target material. This embodiment uses
a stationary cutting tool. Other embodiments use rotating and or swiveling
cutting tools.
Fig. 62 is a side view of a cutting tool 387 and nib 380
combination with safety zone 385. The cutting surface and cutting point 384 are
oriented toward the bottom of the nib. This arrangement makes it easy to cut
and decorate using an average writing instrument angle. An advantage of this
configuration is that when used upside-down, with the cutting tool facing away
from the target material, it is practically impossible to cut the target material
while marking or decorating at a comfortable angel. When used in decorate and
cut mode this device will easily cut and decorate. This embodiment uses a
stationary cutting tool. Other embodiments use rotating and or swiveling cutting
tools.
Fig. 63 shows a top view of an embodiment of the present
invention that uses the top, bottom, and outside surfaces of each of its two nibs
390 and 391 and two sides of the cutting and spacer tool 392. In this
configuration a user can generate 4 major functions and numerous minor
functions. The case 395 has 4 finger grips 393 that, when pointing in a specific
direction, orient the user, with tactile and visual indications 396 and 397. Only
two tactile and visual indicators are shown 396 and 397. In this embodiment
there are four, one on each side, and each tells the user which function they will
be engaging. The tactile and visual indicator 396, when pointing up (parallel to
and on the opposing side of the device away from the target material) tells the
user they will be cutting and decorating. The tactile and visual indicator 397 tells
the user, when pointing up (parallel to and on the opposing side of the device
away from the target material), that the user will be using the broad surface of
the nib 390.
Fig. 64 shows a top view of the tool of Fig. 63 oriented to use the
broad nib. Each of the nibs in this embodiment is fed, via wicking, from the
material storage vessel 394. Other embodiments use separate storage vessels
to allow each nib to use a different decorating and or beneficial material.
Figs. 65-68 show the major functions possible in the embodiments
shown in Fig. 63. Fig. 65 cut and decorate, Fig. 66 heavy line decoration, Fig.
67 dual line decoration without cutting, Fig. 68 fine line decorating. Minor
functions can be obtained by using the device with the nibs oriented at angles
other than perpendicular to the target material. The color, size, texture, shape
and feel of the case is designed to allow a user to access the major and minor
functions of the devices with ease.
Fig. 69 shows an embodiment of the present invention that
sprays/shoots decorating or advantageous material toward a target surface.
Feed tube 406 draws decorating material from the decorating material storage
vessel 403 when gas from a gas source 401 moves through gas supply tube
402 into handle body 400 past valve 409, when it is open. The valve 409 is
operated by stream activation button 408. As the gas passes past the
decorating material feed tube exit 407 it draws decorating material up the feed
tube 406, mixes it with the gas, which is then ejected from the spray nozzle 405
past the cutting tool 404 and onto a target material. The user can decorate by
pressing stream activation button 408 and can also cut by engaging the cutting
tool 404 to the target material. When this is done simultaneously the user will be
cutting and decorating.
Fig. 70 shows a top view of the tool of Fig. 69. Other embodiments
use marking devices as decorating material supply vessels with a compatible
gas supply and a cutting tool instead of the configuration shown. This will allow
markers to replace the material storage vessel 403.
Fig. 71 shows a side view of a tool with a rotating decorating nib
421 fed via wicking from feed wick 426. Decorating material is stored in the
decorating material storage vessel 424 housed in case 425. This embodiment
uses a stationary cutting tool 420 that cooperates with the nib to cut and
decorate. The rotating decorating nib 421 in this embodiment is a nib that
produces a single color wide-line. Other embodiments use a rolling rubber
stamp or shaped nib to produce an interesting design next to the cut edge.
Other embodiments allow the cutting tool and or the nib to be removed or at
least disengaged so as to only allow only cutting or decorating. The thumb grip
423 allows a user to easily orient the device for use. The shaft 422 supports the
rotating decorating nib 421 by attaching it to the stationary cutting tool 420. The
stationary cutting tool 420 acts as a cutting tool and a support for the shaft 422
and rotating decorating Nib 421. Other embodiments use multiple cutting tools
and or multiple nibs. Nut 427 attaches the rotating decorating nib 421 to shaft
422 and bearing 428 assists the rotating decorating nib 421 spinning during
use. Other embodiments use different configurations of rotating decorating nibs
421 and stationary cutting tool 420 to create different advantages.
Fig. 72 shows a front view of the tool of Fig. 71.
Fig. 73 shows an embodiment of the present invention using a
rotating cutting tool 431 and a stationary decorating nib 430. The nib 430 and
rotating cutting tool 431 are held via support shaft 437. Decorating material
storage vessel 434 is housed in case 435. Thumb grip 433 orients the user and
helps to maintain a firm grip while the device is being used. Bearing 438 allows
the rotating cutting tool 431 to rotate freely during use. Nut 432 holds the
rotating cutting tool 431 on the shaft.
Fig. 74 is a front view of the tool shown in Fig. 73.
Fig. 75 shows a rotating cutting tool 441 sandwiched between two
rotating nibs 440 which create a safety zone 446 around the entire perimeter of
the rotating cutting tool 441. A centrally located shaft hole 448 allows the device
to be attached to a shaft and used as a safer rotating cutter.
Fig. 76 shows an embodiment of the tool shown in Fig. 75. A
rotating cutting tool 441 is sandwiched between two rotating nibs 440. A handle
444 is attached to support 443 that uses a bolt 442 to act as a shaft and hold
the rotating nibs 440 and sandwiched rotating cutting tool 441.
Bolt 442 holds the two rotating nibs 440 with the sandwiched
rotating cutting tool 441 and wave spring 445 using a nut 447. The wave spring
445 allows one to adjust the tension squeezing the rotating cutting tool 441 and
rotating nibs 440. The rotating nibs 440 are here to provide a safety zone 446
protecting material from accidentally coming in contact with the cutting tool. This
embodiment does not wick any decorating material to the rotating nibs 440. The
purpose of this invention is to create a safer rotary cutter. Other embodiments
use different support structures with multiple supports and even decorating nibs
with designs on them and shaped rotating cutting tools.
Referring to Fig. 77 there is shown a front view of a cutting tool
support 504 with depth stop 500 and cutting tool 501. The cutting tool support
504 is inserted into a case and is supported by support fin 505. Support
shoulder 503 keeps the cutting tool support 504 in place and biases against it
from being unintentionally forced into a case during use. The cutting tool
support 504 depth stop 500 is set at an angle that is comfortable for use in a
normal writing position. Other embodiments include other angles. Cutting tool
501 is oriented so that it will cut a target material when moved such that the
sharp cutting edge is toward the cutting direction. The cutting tool 501 is welded
to the cutting tool support 504 in a manner that allows only a specific portion of
the blade to extend beneath the depth stop 500. The extended portion of the
blade is called the active cutting surface 502. The active cutting surface 502
protrudes below the depth stop 500 the specific distance it is intended to cut. In
this embodiment the cutting distance is set to about five thousands of an inch
(.005). This will allow the active cutting surface to cut only one sheet of a
standard sheet of average copiers paper and also will cause the device to be
unable to cut skin making the device very safe for use. Other embodiments of
this invention set the active cutting surface 502 to allow it to cut through thicker
or thinner sheets and to allow it to perform cuts on other materials that could
also include skin.
Figure 78 shows the side view of the device shown in Figure 77.
Depth stop 500 is set to bias the possible cutting depth of the cutting tool 501.
Active cutting surface 502 is seen below the depth stop 500.
Figure 79 shows the bottom view of the device shown in Figure
78.
Figure 80 shows a side view of a decorating and cutting device
that uses the cutting tool support 504 with depth stop 500 and cutting tool 501
and nib 521 with safety zone 524. Also shown are the case 520 and decorating
and/or beneficial material storage vessel 522 and cap 523. In this embodiment
the nib 521 distributes decorating and/or beneficial material wicked from the
decorating and or beneficial material storage vessel 522 onto target material.
When enough pressure is exerted to compress the nib 521 safety zones 524
the cutting tool 501 will engage the target material and penetrate, as pressure is
applied, until the depth stop 500 interfaces the target material. When the device
engages the target material, the device is moved in a direction that allows the
cutting tool's 501 active cutting surface 502 to cut to a maximum depth set by
the depth stop 500 while the nib 521 decorates.
Figure 81 illustrates the assembly of the tool 501. Left nib 530,
cutting tool support 504 with cutting tool and depth stop and right nib 531 are
sandwiched together to case 520 (Fig. 80). Spring 532 holds the nib and
cutting tool assembly together at the tip while the case 520 holds together the
balance of the body of the nibs and cutting tool support structure. Other
embodiments use different supports including plastic molded nib holders with
depth stop molded into the structure and other such designs allowing the nibs to
cooperate with the blade and depth stop. Cap 523 protects the nibs 530 and
531 and cutting tool and any materials they may come in contact with.
Figure 82 shows a front view of an embodiment of the present
invention that uses a rotating cutting tool 543 with cutting edge 540 ground on
at least one side and attached to cutting tool support 545 by shaft rivet 541.
The cutting tool support 545 is inserted into a case and is supported by support
fin 505. Support shoulder 503 keeps the cutting tool support 545 from being
unintentionally forced too far into a case during use.
Figure 83 is a side view of the device shown in Figure 82. Shaft
rivet 541 attaches the rotating cutting tool 543 to the cutting tool support 545.
Cutting edge 540 extends a specific depth below the depth stop 500. This
allows the device to cut only to the set dept.
Figure 84 shows a bottom view of the device shown in Figure 82.
Figure 85 shows a front view of the rotating cutting tool 543. In
this embodiment the rotating cutting tool 543 has a ground edge 542 on only
one side. This allows the depth stop to work more effectively because it keeps
the active cutting edge 540 directly adjacent to the depth stop 500. Shaft bore
544 is sized so that it will ride freely on shaft rivet 541.
Figure 86 shows a side view of a cutting tool support 545 with
rotating cutting tool 543 attached by shaft rivet 541 penetrating only two sheets
of the five sheets of paper 562 it is engaged against. The active cutting edge
540 extends the thickness of two sheets of paper beneath the depth stop 500.
Other embodiment set the rotating cutting tool 543 in different locations that
allows consistent and repeatable cuts to be made to specific predetermined
depths. This is useful when considering the operations of cutting the top sheet
of one sheet of paper or if one needed to cut only the top eight sheets of 20
sheets of paper or when needing to accommodate different thickness of and/or
grades and/or types of materials.
Figure 87 shows a front view of a cutting tool support 504 with
depth stop 500 and cutting tool 501 whose active cutting surface 502 set to cut
only the top sheet of the stack of 5 pieces of paper 562. Other embodiments
set the relationship between the cutting tool 501 and blade stop 500 to perform
differently by allowing them to cut deeper or shallower.
Figure 88 shows a front view of a cutting tool support 568 with
cutting tool depth slot 561. The cutting tool depth slot 561 allows the rotating
cutting tool 565 to be moved closer or farther from the target material and in
relation to the depth stop 500. This embodiment of the rotating cutting tool 565
is attached to the cutting tool support 568 by a screw 560 and nut 570. By
loosening the screw 560 and nut 570 and moving the rotating cutting tool 565
toward or away from the target material the rotating cutting tool 565 is
positioned to cut as deep or shallow as desired or not at all. This embodiment
is set to cut only the top sheet of the stack of 5 pieces of paper 562.
Figures 89 and 90 show a front view of the cutting tool 565
showing the ground surface 567 and the square hole 566 that is used to align
the cutting tool 565 to the correct angle no matter where it is positioned on the
cutting tool support by the screw 563 and held in place by nut 571. The screw
563 holds a square spacer 572 that aligns the cutting tool 565 in alignment with
cutting tool depth slot 561 and thus the ground edge at the correct cutting angle.
