REUBEN B. CREASY, OF BALLINGER, TEXAS.
SAW FILING AND GUMMING MACHINE.Specification of Letters Patent. Patented Mar. 4,1913.
Application filed June 29, 1911. Serial No. 636,051.To all whomit may concern:
Be it known that I, REUBEN B. CREASY, a
citizen of the United States, residing at Bal-
linger, in the county of Runnels and State
5 of Texas, have invented certain new and
useful Improvements in Saw Filing and
Gumming Machines, of which the following
is a specification.
This invention has relation to filing and
10 gumming machines for saws adapted to be
used in gins and delinters, and has for its
object, first, to provide means adapted to
be operated automatically or by hand for
moving the saws with relation to the file
15 and for moving the file with relation to the
saws to accomplish the sharpening and gum-
ming operation.
Another object of the invention is to pro-
vide, in combination with a machine, means
90 for supporting a gang of saws so that their
teeth may be presented at any desired angle
to the sharpening file.
A further object of the invention is to
provide, in a machine of the character
25 stated, holding pawls adapted to engage the
teeth of the saws and serve as means for ro-
tating the saws prior to the sharpening op-
eration and as means for holding the saws
during the sharpening operation. These
30 pawls are two in number and have a pecul-
iar relation as will be explained hereinafter.
A further object of the invention is to
provide a movable frame for the file which
is operatively connected with the means for
35 operating the holding pawls and which is
so mounted that it may be moved independ-
ently of the holding pawls.
A further object of the invention is to
provide, in a machine of the character indi-
40 cated, means whereby each tooth of the saw
may be filed to any desired extent and each
tooth may be operated upon irrespective of
its position upon the rim of the saw, that
is to say the teeth may be in circular aline-
45 ment or they may be out of circular aline-
ment, but the sharpening and gumming op-
eration may be accomplished irrespective of
such alinement.
A further object of the invention is to
50 provide, in a machine of the character in-
dicated, an adjustable means for regulating
the depth at which the file will operate upon
the teeth within the edge of the saw and
at the same time to provide means for per-
55 mitting the said file to operate at extraor-dinary distances within the rim of the saw
under variable or extraordinary circum-
stances.
A further object of the invention is to so
assemble and arrange the parts that the ex- 60
tent of cut of the file in the throat be-
tween the teeth of the saws may be regu-
lated and directed as occasion or circum-
stances may require.
In the accompanying drawings: -Figure 65
1 is a side elevation of the machine with
parts in section; Fig. 2 is a top plan view
of a portion of the machine; Fig. 3 isa
vertical sectional view of a portion of the
machine cut on the line 3-3 of Fig. 2; Fig. 70
4 is a transverse sectional view of a portion
of the machine cut on the line 4-4 of Fig.
1. Fig. 5 is a detail plan view of pawls
used upon the machine.
Corresponding and like parts are referred 75
to in the following description and indi-
cated in all the views of the accompanying
drawings by the same reference characters.
The machine includes a frame 1 which is
preferably a structure of wood having at 80
its top and in the vicinity of its front and
rear edges rails 2 and 3 respectively which
extend longitudinally of the said frame.
The rail 3 is provided with a smooth upper
bearing surface while the rail 2 is provided 85
at its upper portion with a series of teeth
adapted to receive between them part of a
carriage to be explained hereinafter, where-
by the said carriage is held in an adjusted
position upon the said rails. Plates 4 (of 90
which one only is shown) are mounted upon
the intermediate end portions of the frame 1
and adjusting screws 5 are threaded through
the said plates. Blocks 6 are mounted upon
the upper surfaces of the plates 4 and the 95
upper ends of the said screws 5 bear di-
rectly against the lower surfaces of the said
blocks. Therefore it will be seen that by
turning the screw 5 the blocks 6 may be
raised or lowered with relation to the plate 100
4. Lugs 7 are mounted upon the end por-
tions of the frame 1 at the opposite sides of
the plate 4 and carry adjusting screws 8
which bear at their inner ends against the
opposite sides of the block 6. Therefore it 106
will be seen that by turning the screws 8 the
block 6 may be adjusted horizontally over
the. plate 4. A bearing 9 is carried by each
block 6 and is provided at its upper side
with a recess 10. 1101,054,908.
