is set forth.
DETAILED DESCRIPTION OF THE INVENTION
[0064] The present invention deals with obtaining articles that are
cut to precise measurements. In particular, the invention deals
with woodworking, however, it also has applicability to
metalworking as well. The invention is uniquely adapted to the
amateur woodworker or metalworker as well as to professionals.
[0065] In particular, it is difficult to make precise angled cuts
utilizing even the most sophisticated saw blades. For example, a
typical table saw has a planar surface on which a workpiece such as
wood is placed. The saw blade in a typical table saw is circular
and extends through the planar surface of the table saw.
[0066] The first difficulty in dealing with a table saw is that the
legs or base of the table saw touching the floor of the structure
in which the table saw is placed may not be perfectly level. The
second difficulty in dealing with the table saw is that even if the
legs terminate in a single plane is that the floor of the structure
in which table saw is placed may not be perfectly level. Thirdly,
even though the table saw will typically have a crank control to
permit adjustment of the saw in relation to the planar surface of
the table saw the original adjustment of the crank control relative
to the planar surface of the table saw and/or the blade may result
in an out of specification problem. Out of specification problem
means that, for instance, when the saw blade is desired to be at 90
degrees to the planner surface of the table saw that some other
condition causes of the saw blade to be in a different orientation.
The out of specification condition may result from poor
manufacturing techniques, damage during shipping, or through wear
the table saw.
[0067] The present invention provides and effective method of
correcting out of specification conditions. Thus, planar surface of
a table saw and the table saw blade may be correctly oriented to
provide a correct orientation throughout the entire range that the
table saw is intended to cut.
[0068] As best seen in FIG. 1 is a leveling device 10. The leveling
device 10 is comprised in part of a leveling device base 12. The
leveling device base 12 has a leveling device base upper surface
14. Opposite the leveling device base upper surface 14 is a
leveling device base lower surface 16.
[0069] A leveling device base magnet 20 is located on the leveling
device base lower surface 16. The leveling device base magnet 20
may cover substantially the entire surface of the leveling device
base lower surface 16. Alternatively, the leveling device base
magnet 20 may be segmented into one or more parts. In one
embodiment, the leveling device base magnet 20 has a spaced apart
region between two separate magnets 20A and 20B as shown in FIG.
6.
[0070] A leveling device vertical riser 24 rises perpendicularly
from the leveling device base upper surface 14. The leveling device
vertical riser 24 may be an integral part of the leveling device
base upper surface 14. The leveling device vertical riser 24 may
also be a separate piece affixed to the leveling device base upper
surface 14. The leveling device vertical riser 24 may be affixed to
the leveling device base upper surface 14 by welding, adhesives,
screws or the like. Conveniently, the leveling device vertical
riser 24 as a general shape of a mantle clock when viewed from the
front.
[0071] A leveling device vertical riser channel 28 is located
through the leveling device vertical riser 24. The leveling device
vertical riser channel 28 is generally perpendicular to the
lengthwise direction of the leveling device vertical riser 24. That
is, the leveling device vertical riser channel 28 will also be
generally perpendicular to the leveling device base upper surface
14. The leveling device vertical riser channel 28 is threaded.
[0072] A leveling device threaded screw mechanism 32 is devised of
a sufficient length and the diameter to extend through and beyond
the leveling device vertical riser channel 28. The purpose of the
leveling device threaded screw mechanism 32 is more particularly
shown according to FIG. 5.
[0073] A leveling device first floating washer 36 is associated
with the leveling device threaded screw mechanism 32 when the
leveling device 10 is assembled. Typically, the leveling device
first floating washer 36 is cylindrical. A leveling device first
floating washer opening 44 extends through the circumferential
center of the leveling device first floating washer 36. The
leveling device first floating washer 36 has a typical thickness of
about 10 percent of the diameter of the leveling device first
floating washer 36.
[0074] A leveling device second floating washer 40 is also
associated with the leveling device threaded screw mechanism 32
when the leveling device 10 is assembled. Typically, the leveling
device second floating washer 40 is cylindrical. A leveling device
second floating washer opening 48 extends through the
circumferential center of the leveling device second floating
washer 40. The leveling device second floating washer 40 has a
typical thickness of about 10 percent of the diameter of the
leveling device second floating washer 40.
[0075] A leveling device cylindrical workpiece 52 is employed with
the leveling device first floating washer 36 as best seen in FIG.
5A leveling device cylindrical workpiece 52 has a first opening 60.
A leveling device cylindrical workpiece 56 is best seen in FIG. 5B.
The leveling device cylindrical workpiece 56 has an opening 64.
[0076] As best seen in FIG. 7 is a leveling device vertical riser
24. The leveling device vertical riser 24 has a generally mantle
clock shaped. The leveling device vertical riser 24 has leveling
device vertical riser channel 28 toward the upper region of the
leveling device vertical riser 24.
[0077] As shown in FIG. 8 is a leveling device lock washer 68. The
leveling device lock washer 68 is generally mantle clock shaped.
The leveling device lock washer 68 has a leveling device lock
washer 72. The leveling device lock washer 72 has a flat base. A
leveling device vertical riser channel 74 extends through the
leveling device lock washer 68. As noted, the leveling device lock
washer 68 and leveling device vertical riser 24 are similarly
shaped and in assembly substantially overlap one another. The
leveling device lock washer 68 is intended as a lock washer to
reduce torque when the leveling device 10 is assembled and in
use.
[0078] Turning to FIG. 2, a leveling device locking screw nut 76 is
shown. The leveling device locking screw nut 76 is of conventional
design and is threaded on the interior to receive the leveling
device threaded screw mechanism 32. Also has seen in FIG. 2 is a
leveling device locking screw nut 80. The leveling device locking
screw nut 80 is comparable to size and function to the leveling
device locking screw nut 76. The leveling device locking screw nut
80 receives the opposite end of the leveling device threaded screw
mechanism 32.
[0079] As best seen in FIG. 1 is the leveling device 84 protractor
of the leveling device 10. When assembled, the leveling device 84
protractor is held in place by action of the leveling device
locking screw nut 76 on the leveling device first floating washer
36.
[0080] The leveling device 84 protractor has a leveling device
protractor obverse side 86. A leveling device protractor scale 92
is displayed on the leveling device protractor obverse side 86.
[0081] A leveling device protractor reverse side 90 is opposite the
leveling device protractor obverse side 86. A leveling device
protractor window 118 is located within the leveling device 84
protractor. When in use the leveling device protractor window 118
permits viewing of the leveling device protractor scale 92. A
leveling device sight line 120 is positioned to bisect the leveling
device protractor window 118. The leveling device sight line 120 if
extended also bisects the leveling device horizontal bubble level
106 and the leveling device vertical bubble level 112.
[0082] A leveling device bubble retention mechanism 100 extends
from the leveling device base 12. The leveling device bubble
retention mechanism 100 provides a leveling device horizontal
bubble level 106 and a leveling device vertical bubble level 112.
The leveling device horizontal bubble level 106 is located
perpendicularly to the leveling device vertical bubble level 112.
The leveling device horizontal bubble level 106 is a conventional
item giving a horizontal measurement when the leveling device 10 is
placed on a planner surface. The leveling device vertical bubble
level 112 provides a leveling measurement when placed on a vertical
planner surface.
[0083] A leveling device protractor window 118 is located within
the leveling device bubble retention mechanism 100. The leveling
device protractor window 118 permits viewing and reading of the
leveling device protractor scale 92.
[0084] The leveling device 10 is assembled by attaching to the
leveling device base 12 to the leveling device vertical riser 24.
As previously noted, the leveling device vertical riser 24 may be
affixed to the leveling device base 12 by screws, bolts adhesives,
or welding. The leveling device base magnet 20 is affixed to the
leveling device base lower surface 16 on the leveling device base
12. The leveling device locking screw nut 76 is that attached to
the leveling device threaded screw mechanism 32. At a later point
the leveling device 10 is finally assembled the leveling device
locking screw nut 80 is attached to the opposite end of the
leveling device threaded screw mechanism 32. The leveling device
threaded screw mechanism 32 is inserted through the leveling device
first floating washer 36 to the leveling device cylindrical
workpiece 52 through the leveling device cylindrical workpiece
first opening 60. The leveling device threaded screw mechanism 32
is inserted through the leveling device protractor passage 96 and
through the leveling device protractor reverse side 90.
[0085] The leveling device threaded screw mechanism 32 is then
passed through the leveling device vertical riser channel 28 in the
leveling device vertical riser 24 through the leveling device
protractor obverse side 86 and the leveling device cylindrical
workpiece 56. The leveling device threaded screw mechanism 32
continues through the leveling device second floating washer 40 and
leveling device threaded screw mechanism 32 is then affixed to the
78. The length of the leveling device threaded screw mechanism 32
is such that when the respective leveling device first floating
washer 36 or leveling device second floating washer 40 are
tightened the threading within the leveling device vertical riser
channel 28 permits a secure holding of the leveling device
protractor obverse side 86 or the leveling device bubble retention
mechanism 100 in place.
[0086] In the assembled leveling device 10 is then ready for use.
As best seen in FIG. 9 is a partial view of a table saw 130. The
table saw 130 has an adjustable table saw blade 134. The table saw
130 has a table saw planar surface 140. The table saw blade 134
passes through an opening in the table saw planar surface 140. The
cutting angle of the table saw blade 134 is adjusted with a table
saw leveling mechanism 150. The table saw leveling mechanism 150
permits the table saw blade 134 to be adjusted between 45 degrees
and plus 45 degrees.
[0087] Typically, a table saw 130 will be able to cut anywhere from
positive 45 degrees to negative 45 degrees from the planar surface
of the table saw. That is, when an angle greater than 45 degrees is
desired to cut to the workpiece is made utilizing the opposite side
of table saw blade. Thus, when a cut of 60 degrees is desired to a
workpiece on the positive side of the planner surface of the table
saw then the cut is made at the negative 30 degrees setting for the
orientation of the table saw blade.
[0088] As previously noted, in a perfect world, the table saw
planar surface 140 of the table saw blade 134 would lie in a plane
such that the table saw blade 134 when set to 0 degrees is
perpendicular to the plane of the table saw planar surface 140.
However, in reality the table saw blade 134 may not be
perpendicularly aligned when the table saw leveling mechanism 150
has a 0 degrees setting due to the legs of the table not providing
a flat surface. Moreover, adjustments to the table saw leveling
mechanism 150 may indicate that the 0 degree reading on the table
saw blade 134 is otherwise not accurate. Further, in many
conventional table saws 130 the table saw leveling mechanism 150 is
significantly below the level of the table saw planar surface 140
thereby making adjustments by the table saw leveling mechanism 150
difficult.
[0089] As best seen in FIG. 11, the leveling device 10 is placed on
the table saw planar surface 140. A reading and adjustment of the
leveling device horizontal bubble level 106 through the leveling
device protractor window 118 will permit adjustment by the table
saw leveling mechanism 150 to a desired setting (in this case 0
degrees). The leveling device 10 maybe then placed on the table saw
blade 134. The leveling device 10 is retained on the table saw
blade 134 by the leveling device base magnet 20. The table saw
blade 134 may be permitted to move slightly as of the leveling
device vertical bubble level 112 operates on the floating bubble
principle. Thus, a reading of may be determined to see if the
bubble is centered within the leveling device vertical bubble level
112. If the bubble is not centered within the leveling device
vertical bubble level 112 then the table saw leveling mechanism 150
may be adjusted until of the leveling device vertical bubble level
112 is centered.
[0090] If adjustment is desired to be outside of the 0 degree
setting then in the leveling device 10 is placed on the table saw
planar surface 140 and adjusted to the desired reading such as a
left tilt of 30 degrees. The leveling device locking screw nut 76
is done appropriately tightened to retain the leveling device
bubble retention mechanism 100 in the correct orientation at a left
tilt of 30 degrees. At this point of the leveling device 10 is
affixed to the table saw blade 134 by the leveling device base
magnet 20. A reading of the leveling device vertical bubble level
112 is then made. If the bubble is not centered on the leveling
device vertical bubble level 112 then the table saw leveling
mechanism 150 may be appropriately adjusted so that the leveling
device protractor obverse side 86 then gives a level bubble reading
of the leveling device vertical bubble level 112.
