Description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] The invention relates generally to holders for sharpening
tools. More particularly, the invention relates to holders for
sharpening gouges with a grinding wheel. Specifically, the
invention relates to a gouge sharpening holder with multiple pivot
axes, a guide cam, and an axially slidable mount to produce a
precision grind.
[0003] 2. Background Information
[0004] A chisel is a tool used for removal of material from work
pieces such as stone, metal, and wood. The chisel generally
includes two distinct ends. The first end is the material removal
end, while the second end is the handle. The material removal end
is made with various materials and designs depending on the task at
hand. The handle end is shaped to allow the user to securely grasp
the chisel and may include a hardened tip so that the chisel can be
hit with a mallet or hammer to force the material removal end into
and through the work piece. When the material end of the chisel is
forced through the work piece, material removal and shaping is
achieved.
[0005] Woodworking chisels are also immensely popular since wood
can be manipulated easier than harder materials. Accordingly, a
variety of chisels have been developed to accommodate the various
needs of woodworkers. Among the specialized chisels are butt
chisels, slick chisels, paring chisels, skew chisels, and carving
chisels. The carving style chisel also includes a gouge chisel
which is used to create a generally concave surface in the work
piece. The gouge chisel creates a generally concave surface due to
the chisel's U-shaped cross-section. A gouge chisel may be either
incannel, where the cutting edge is within the U-shaped
cross-section, or outcannel, where the cutting edge is on the
outside surface the chisel.
[0006] With use, the leading edge of the gouge becomes dull and
does not cut or remove material as efficiently. The woodworker must
then proceed to sharpen the leading edge. This may be done free
hand on a grinding wheel or on a sharpening stone. The use of a
grinding wheel makes the sharpening procedure much easier and less
time consuming. However, free hand sharpening of a gouge is
difficult due to the precision needed in forming the leading edge
along the U-shaped cross-section. Further, the grinding wheel in
inherently dangerous because the user must apply pressure in the
direction of the grinding wheel. If the tool slips off or catches
an edge, the user could fall into the grinding wheel and cause
severe injury to himself/herself.
SUMMARY OF THE INVENTION
[0007] The present invention broadly comprises a sharpening guide
for use with a chisel and a grinding wheel comprising a rod having
a first end and a second end, a pivot assembly carried by the first
end, a tool clamp attached to the pivot assembly and movable
relative to the rod and adapted to retain the chisel, a base, and a
base pivot for movably mounting the rod relative to the base
whereby the base pivot is adapted to be mounted adjacent the
grinding wheel.
[0008] The present invention also broadly comprises a method of
sharpening a tool comprising the steps of locating a tool within a
tool clamp, rotating the tool clamp toward a grinding wheel about a
first axis until the tool is in contact with a grinding wheel, and
rotating the tool clamp about a second axis to move the tool across
the grinding wheel rotationally.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0025] At the outset, it should be appreciated that like drawing
numbers on different drawing views identify identical, or
functionally similar, structural elements of the invention. While
the present invention is described with respect to what is
presently considered to be the preferred embodiments, it is to be
understood that the invention as claimed is not limited to the
disclosed aspects.
[0026] Unless defined otherwise, all technical and scientific terms
used herein have the same meaning as commonly understood to one of
ordinary skill in the art to which this invention belongs. Although
any methods, devices or materials similar or equivalent to those
described herein can be used in the practice or testing of the
invention, the preferred methods, devices, and materials are now
described.
[0027] The gouge sharpening tool holder of the present invention is
indicated generally at 14, as is particularly shown in FIGS. 1
through 12. As particularly shown in FIG. 1, a preferred embodiment
gouge sharpening tool holder 14 includes a base 16 and a rod 18.
The gouge sharpening tool is secured to a table 20 or other
suitable sturdy surface with bolts 22. A grinding wheel 24,
includes an outer surface 26 which rotates about axis 25, is
secured to the table and located proximate the tool holder.
[0028] In accordance with one of the main features of the present
invention, base 16 includes a base beam 28 slidable within a mount
30. Averting to FIGS. 1, 2, and 3, the mount further includes a
clamp 32 with a handle 34 and a lock 36. Lock 36 is preferably an
enlarged cam with a larger diameter when handle 34 is rotated to a
locked position and a smaller diameter when handle 34 is rotated to
an unlocked position. In particular, lock 36 is tapered from a
smaller diameter to a larger diameter to allow the clamp to lock
base beam 28 in one position and unlock base beam 28 is a second
position. Thus, base 16 is axially slidable through clamp 32 when
the clamp is in the unlocked position and base 16 is fixed when
clamp 32 is in the locked position.
[0029] Base beam 28 preferably includes a square cross-section and
is oriented such that an edge of base beam 28 rests in the back
inner portion of mount 30. Although the cross-section is preferably
square, any shape that can be locked in position may be
utilized.
[0030] Base 16 also includes a first end 38 a pair of spaced apart
and parallel plates 39 having a pivot connection 40. Interposing
first end 38 and base beam 28 is an enlarged member 42. A cam base
44 is complimentary shaped to fit over enlarged member 42 and still
allow cam base 44 to slide along the outer surface of the enlarged
member. Cam base 44 also includes a guide 46 pivotally mounted to
cam base 44 at a thumb screw 48. In particular, when thumb screw 48
is loosened, guide 46 is capable of pivoting about the connection
at thumb screw 48, and when the thumb screw is tightened, guide 46
is then fixed.
[0031] Viewing FIGS. 1 and 4, guide 46 includes a first plate 45
and a second plate 47. The first plate is rotationally secured to
the enlarged member at thumb screw 48. The first plate spaces the
second plate away from upwardly extending plate 43 and both
enlarged member 42 and cam base 44. The second plate is generally
perpendicular to first plate 45 and arranged to communicate with
cam 62 (described infra). In particular, an outer surface 49 of
second plate 47 is in frictional engagement with surface 63 of cam
62.
[0032] In accordance with another main feature of the present
invention, base pivot 40 is attached to a housing 50. The housing
is preferably rectangular or square in shape with a hole (FIG. 3)
traversing the length of housing 50 and terminating at a boss 54 on
a top surface and a boss 56 on a bottom surface. Preferably,
housing 50 includes an upper bushing 53 with boss 54 and a lower
bushing 55 with boss 56. Rod 18 is arranged to slide within hole 52
in bushings 53 and 55. A height adjuster 58 is secured to rod 18
and includes a bottom side located adjacent boss 54. The height
adjuster is preferably a disc with a machined bottom surface to
smoothly and evenly abut boss 54. Further, height adjuster 58 is
removably secured around rod 18 and can be tightened or loosened at
a bolt 60. Accordingly, height adjuster 58 can be located along the
length of rod 18 as desired to control the height between housing
50 and the tool (described infra).
[0033] A cam 62 is located above height adjuster 58. Similar to the
height adjuster, cam 62 surrounds rod 18 and is removable by
loosening a bolt 64. Cam 62 is generally a right cylinder with a
hole 66 traversing the length. In a preferred embodiment, hole 66
is offset from the center of cam 62 and allows non-uniform, or a
parabola-like shape at an outer surface of the cam upon rotation of
rod 18. Since the hole is offset, one side of cam 62 is further
away from rod 18 than the opposing side of cam 62, thus meaning
that rod 18 is spaced further away from plate in 47 some cam
positions while being closer to plate 47 in other cam positions.
Further, cam 62 rides against second plate 47 of guide 46 when the
tool holder is pivoted towards grinding wheel 24 at pivot
connection 40. Although the cam is shown and described as having a
generally circular cross-section, it is within the spirit and scope
of the invention to provide a cam with a variety of cross-sectional
shapes.
[0034] As particularly seen in FIG. 3 and upward of cam 62, rod 18
may have a square cross-section portion at 68 of the rod. A second
pivot connection 70 is located at the end of rod 18 that is distal
base 16. Pivot connection 70 preferably includes a bolt 72
proximate a wall 73, a groove 74 in the end of rod 18, and a nut 76
welded to a wall 78. Pivot connection 70 includes walls 73 and 78
which extend upwardly and are spaced apart to receive a tool
holding portion 80. Rotation at pivot connection 70 is prevented
when bolt 72 is tightened at nut 76. Thus, pivot connection 70
allows tool holding portion 80 to rotate when bolt 72 is loosened
and prevents rotation of the tool holding portion by compressing
walls 73 and 78. 5 In a preferred embodiment, tool holding portion
80 includes a first side wall 82 and a second side wall 84 spaced
apart at the top by an upper wall 86. First side wall 82 and second
side wall 84 are angled inwards toward each other at the bottom of
the tool holding portion and meet at and inside of pivot connection
70. Inner walls of first side wall 82, second side wall 84, and
upper wall 86 form a cavity 88. At the lower portion of cavity 88,
first wall 82 and second wall 84 are arranged in a V-shape to
easily center the tool.
[0035] The tool is held in place by a bearing 90 which is in turn
connected to a threaded rod 92 and a knob 94. Bearing 90 is
preferably used because it will rotate slightly upon axial
displacement and help insure that the tool is centered within the
holding portion. The threaded rod passes through a threaded hole 96
in upper wall 86 of the tool holding portion. Accordingly, rotation
of knob 94 rotates threaded rod 92 through hole 96 and axially
displaces bearing 90 to selectively secure or release a tool.
[0036] Tool holding portion 80 further includes a tool alignment 98
connected to second side wall 84 in a preferred embodiment; however
it is within the spirit and scope of the present invention to
locate the tool alignment on any suitable portion of the tool
holding portion, including first wall 82 or upper wall 86. Tool
alignment 98 includes an alignment rod 100 with a first end 102 and
a second end 104. A band 106 surrounds first end 102 and is
slidable along the length of the alignment rod. First end 102 of
rod 100 slides through a hole 107, complimentarily sized and
shaped, in side wall 84. Since hole 107 is sized to allow only rod
100 to slide, band 106 prevents the alignment tool from extending
beyond the length set by band 106. Thus, band 106 is set along the
length of first end 102 such that rod 100 and second end 104 extend
past a front side 108 of the tool holder and second end 104
provides the length that a tool to be sharpened must be inserted
beyond the tool holding portion front side for proper
alignment.
[0037] Averting to FIG. 4, rod 18 is shown traversing hole 52 in
housing 50, height adjuster 58, and cam 62. Hole 66 of cam 62 is
preferably offset from the center of cam 62 to match the desired
contour of the tool (discussed infra). Further, guide 46 is
arranged adjacent an outer surface 63 of cam 62 and rotation of rod
18 imparts eccentric rotation of cam 62 along second plate 47 of
guide 46.
[0038] FIG. 5 is a cross-sectional view of cam base 44 disposed on
enlarged member 42. Further base beam 28 is welded to enlarged
member 42 in a preferred embodiment. Since cam base 44 is
complimentarily shaped to enlarged member 42, cam base 44 is
slidable along the length of the enlarged member. The cam base is
fixed in place by rotation of screw 110 in a clockwise direction
and released for movement in a counterclockwise direction. As
described supra, thumb screw 48 allows adjustability of guide 46. A
washer 112 separates upwardly extending plate 43 of cam base 44 and
first plate 45 of guide 46, while another washer 112 separates
thumb screw 48 and first plate 45 of guide 46.
[0039] Having described the structure of the preferred embodiment,
a preferred method of operation will be described in detail and
should be read in light of FIGS. 1 though 11, and particularly
FIGS. 6 through 11.
[0040] As seen in FIG. 6, a tool 114 is shown being inserted
through cavity 88 in the direction associated with arrows 116. Tool
114 also includes a first end 118 terminating in a tip 120. Band
106 is located on rod 100 in a position that allows rod 100 to
extend beyond front side 108 and band 106 to rest against hole 107.
Accordingly, tool 114 is inserted through cavity 88 until tip 120
is aligned with rod second end 104 to prepare the tool for
sharpening. While the present invention is shown sharpening a gouge
tool, any tool which requires sharpening with a contour may be
utilized.
[0041] Next, FIG. 7 is a cross-sectional view of tool holding
portion 80 with first end 118 of tool 114 secured by axial force in
the direction associated with arrow 121 of bearing 90.
Specifically, knob 94 is rotated and bearing 90 forces tool 114
downward by pushing on edges 122 and sets the tool in V-shaped
cavity 88 formed by first wall 82 and second wall 84. When tool 114
is secured within tool holding portion 80, the tool is supported by
bearing 90 on the top and by first wall 82 and second wall 84 on
the bottom. After the tool is properly located and secured, tool
alignment 98 is returned in the direction associated with arrow 124
to prevent damage to the tool alignment.
[0042] FIG. 8 exemplifies the next two steps, whereby base 16 and
base beam 28 is axially moved in the direction associated with
arrow 126. To this end, handle 34 is rotated (as seen in FIG. 2) to
release clamp 32 and allow base beam 28 to slide within base mount
30. After the clamp is released, base beam 28 is moved in the
direction of arrow 126 to locate tip 120 proximate grinding wheel
outer surface 26. Next, tool sharpening holder 14 is pivoted about
pivot connection 40 in the direction associated with arrow 128.
Further, the user imparts a constant force in the direction
associated with arrow 130 such that cam 62 and surface 63 are in
constant communication with second plate 47 and surface 49 of guide
46. Thus the constant force in the direction of arrow 130 means
that any rotation of rod 18 follows the contour of outer surface 63
of cam 62 and translates to a similar contour at tip 120 and tool
first end 118.
[0043] FIG. 9 is a top enlarged view of the tool holder with tool
114 extending through cavity 88 and the tool holding portion
located proximate grinding wheel 26. 1s Tip 120 is also located
proximate grinding wheel outer surface 26. Having taken the above
steps, the tool is now ready to be sharpened or ground after
grinding wheel 24 is turned on and begins to rotate. FIG. 9A is a
partial cross-sectional view looking down the tool holder and
showing cam 62 off center from rod 18 and height adjuster 58.
[0044] As seen in FIG. 10, tool sharpening holder 14 is then
rotated about rod 18 within housing 50 in the direction associated
with arrow 132. In particular, the constant force in the direction
of arrow 130 as described above is still applied, but a rotational
force in the direction of arrow 132 is also applied. Cam 62 is
arranged with outer surface 63 with a contour to the desired grind
of tool end 118. In a gouge tool, the shape is generally parabolic
and is achieved by maintaining tip 120 at constant axial distance
from the grinding wheel outer surface 26. Thus, when the tool is
rotated, the tip remains the same distance from the grinding wheel,
but grinding occurs on a side of the tool end. Further, since outer
surface 63 of the cam rotates eccentric from rod 18, the axial
displacement of tip 120 and tool end 118 is controlled by outer
surface 63 of cam 62 and allows a perfect parabola shape to be
ground into the tool. Although the preferred embodiment is
described with a parabolic, or U-shape, it is within the spirit and
scope of the present invention as claimed to provide a cam with any
shape that matches the desired tool tip contour. FIG. 10A is a
partial cross-sectional view looking down the tool holder and
showing cam 62 off center from rod 18 and being both rotated in the
direction associated with arrow 132 and forced in the direction
associated with arrow 130 into guide 46.
[0045] FIG. 11 is a top view of tool sharpening holder 14 being
rotated in the direction associated with arrow 134, opposite arrow
132, to provide grinding to the opposite side of tool 114. FIG. 11A
is a partial cross-sectional view looking down the tool holder and
showing cam 62 off center from rod 18 and being both rotated in the
direction associated with arrow 134 and forced in the direction
associated with arrow 130 into guide 46.
[0046] In summary, the tool sharpening holder allows a precision
grind of a tool with a non-uniform taper by securing the tool with
only a single axis of rotation and rotating the tool sharpening
holder cam against a guide to provide the desired tool contour.
[0047] Having now described the structure and operation of the
first embodiment, only those portions of the remaining embodiment
which are different from the first embodiment are described in
detail. Likewise, similar numerals refer to similar parts
throughout the various embodiments.
[0048] In accordance with a second embodiment of the invention
shown specifically in FIG. 12 without a cam or guide, tool 114 is
located within the tool holding portion 80. Pivotal connection 70
allows the user to adjust the angle of approach .theta. and to
adjust where on the tool tip 120 the grinding wheel will remove
material. Height adjuster 58 and rod 18 both operate in the same
manner as the first embodiment.
[0049] In operation, the second embodiment locates tool 114 in the
same manner as the first embodiment by using alignment tool 98.
Next, pivotal connection 70 is adjusted to provide the correct
angle of approach .theta. and base 16 is axially moved in the
direction associated with arrow 136 after clamp 32 is released
(which again functions identical to the first embodiment). Once the
tool is located proximate and in slight contact with the grinding
wheel, handle 34 is rotated to clamp beam 28 and base 16 in that
position. Finally, tool 114 is rotated about rod 18 in the
directions associated with arrows 132 and 134 as disclosed in the
first embodiment to sharpen the tool.
[0050] Accordingly, the gouge sharpening tool is an effective,
safe, inexpensive, and efficient device that achieves all the
enumerated objectives of the invention, provides for eliminating
difficulties encountered with prior art devices, systems, and
methods, and solves problems and obtains new results in the
