JAY DELL GE BOTT, OF FOSTORIA. TEXAS.
TOOTH-BENDER.Specification of Letters Patent.
Patented April 20, 1909.
Application filed December 24, 1907. Serial No. 407,927.
To all whom it may concern:
Be it known that I, JA DELL GE BOTT, a
citizen of the United States, residing at Fos-
toria, in the county of Montgomery and State
5 of Texas, have invented certain new and use-
ful Improvements in Tooth-Benders; and I
do declare the following to be a full, clear,
and exact description of the invention, such
as will enable others skilled in the art to I
10 which it appertains to make and use the
same.
My invention relates to tooth benders, and
especially to that type used in connection
with the bending of band saw teeth forward.
15 The object of the invention is to provide a
device which will keep the teeth in proper
shape and form and will place them in condi-
tion to be sent to the filing room for grinding.
A further object of the invention is to pro-
20 duce a device of this character which em-
bodies means for properly forming the tooth,
and with further means for limiting the
shape of tooth so that an improperly-shaped
tooth is an impossibility.
25 A further object of the invention is the
. provision of novel means for securing the de-
vice upon a band saw, and for retracting the
bending plunger.
With these and other objects in view, the
30 invention consists of certain novel features of
construction, combination and arrangement
of parts as will be described hereinafter and
particularly pointed out in the appended
claims.
35 In the accompanying drawing, Figure 1 is
a side elevation; Fig. 2 is a vertical longitudi-
nal sectional view on the line x-x of 'ig. 3;1
Fig. 3 is a transverse central sectional view
on the line y--y of Fig. 2; and Fig. 4 is a de-
40 tail view of the bending plunger.
Referring more especially to the drawings,
1 represents a heavy steel block, preferably
cylindrical in outline, and which is cut away
at 2, to provide a saw-receiving channel
45 which is enlarged at its upper end to provide
a recess, 3, for the widened edges of the saw
teeth. Projecting above the channel, 2, is a
vertical recess, 4, in which is mounted the
plunger cam, 5, keyed upon the transverse
50 shaft, 6, and the reciprocally mounted plun-
ger, 7, having a serrated operating face, 7a.
This plunger is normally held in engagement
with the cam by a leaf spring, 8, secured to
the body, 1, in any suitable manner. Keyed
55 to the shaft, 6, is an operating handle, 9, and
adjustably mounted on a stub shaft, 10, is alimiting stop, 11, which is provided with a
ight-angular extension to engage the arm of-
the handle as it is moved forward to depress
the plunger. 60
The channel, 2, is defined by a pair of legs,
12 and 13, in one of which is threaded a stub
shaft, 14, having an engaging head, 15, lo-
cated inside the channel, and a squared outer
end, 16, to receive the clamping handle, 17. 65
Passing through the legs and the channel is
an eccentrically shaped anvil, 18, which is
seated slightly out of line with the vertial
alinement of the sl aft, 6, and underneath the
plunger, 7, adjacent one edge thereof. This 70
anvil has its ends headed up as at 19 to pro-
vide a brace for the legs and to secure it from
turning. To further secure it from turning,
the apertures in the legs are made eccentric
so as to correspond with the shape of the 75
anvil.
Attached to one edge of the block is a
slotted adjusting member, 20, which has pro-
jecting therefrom a gage arm, 21, having an
adjusting screw, 22, at its outer end, which 80
holds the gage plate or spring, 23, in adjusted
position. The member 20 is secured upon
the block 1 by set screws, 24, and the gage
plate 23 is secured to the arm 21 by a set
screw, 25. A similar gage-arm, 26, has its 85
end let into the block 1 and its opposite gage
end provided with an adjusting screw, 27, to
which is secured an adjusting plate, 28.
It will be seen that I am enabled to adjust
the device upon the band saw teeth as shown 90
in Fig. 1 so as to obtain any desired shape to
the teeth, and I am also enabled to limit the
movement of the plunger by the limiting
stop, 11. Thus two absolute controlling de-
vices are provided which enable me to bend 95
forward the entire lot of teeth on a band saw
uniformly.
From the foregoing description, taken in
connection with the accompanying drawings,
the construction and operation of the inven- 100
tion will be readily understood without re-
quiring a more extended explanation.
Various changes in the form, proportion
and the minor'details of construction may be
resorted to without departing from the prin- 105
ciple or sacrificing any of the advantages of
the invention, as defined in the appended
claims.
Having thus described my invention, what
I claim as new, and desire to secure by Let- 110
ters-Patent, is as follows:
1. In a device of the class described, aNo. 919,153.
