of the lever and serving to regulate the down-
ward throw of the setting-tool carried by the
opposite end of the lever.
Directly beneath the head of the setting-
5 tool is provided a transverse timber G, and
seated within the upper face of said timber
is an anvil-block G'. This block is of steel
and has its face beveled, as shown, and is de-
signed to form a seat against which the saw-
io tooth is driven by the setting-tool. A set-
screw G2, passed through said timber G hori-
zontally, may be employed to move the said
anvil forward or back, as desired, in order to
insure its proper position during the opera-
15 tion of the machine; or, if preferred, a simple
sliding-rod, as shown in the drawings, may
be substituted for the set-screw.
In order to properly limit the throw of the
anvil, I provide shoulders G', which extend
20 for a short distance from the sides of the re-
cess within which the anvil is seated and en-
gage corresponding shoulders upon the anvil,
as shown.
Passed vertically through the upper side
25 timbers A' of the frame are set-screws II.
These screws are arranged at distances apart
corresponding with the difference in width of
saws, and when forced downward to their ex-
treme limitthey extend to the lower timber A'2.
30 In operation the saw-blade to be operated
upon is placed transversely within the recess
between the timbers A' and A2, with the teeth
of the saw in the directionof the anvil. The
saw is then moved forward until the teeth ex-
35 tend a proper distance over the anvil to in-
sure the proper angle of the set. The set-
screw F' is adjusted so as to properly limit
the movement of lever the E'. The file isthen passed vertically through the open ends
of the case BE within the chamber in the off- 40
set B', and thesaid case isadjusted bymeans
of the set-screw B3, so as to bring the face of
the file to the proper point. By moving the
file up and down through the vertical case
within which it has been placed, and at the 45
same time moving the saw longitudinally, it
will be readily seen that all of the teeth will
be brought to a uniform length, and as each
tooth in turn reaches the anvil an upward
movement is imparted to the setting-lever 5o
and the tooth will be set at the desired angle.
Having thus described my invention, what
I claim to be new, and desire to secure by Let-
ters Patent, is-
1. In a device of the character described, 55
the combination of the main frame having
end section having offset portion, the rect-
angular case therein with open side, the ad-
justing-screw acting on said case, and the
timber C, having extension C . with rectangu- 60o
lar openings, as set forth.
2. The combination of the main frame hav-
ing a recess for the reception of the saw,
means, as described, for adjusting the saw
within the recess, an adjustable anvil, a piv- 65
oted setting-tool having curved operating-
handle, and means for limiting the movement
of the setting-tool, substantially as and for
the purpose described.
In testimony whereof I affix my signature in 70
presence of two witnesses.
