McDUFFEE BRADFORD, OF NOCONA, TEXAS.
GIN-SAW CLEANER.No. 865,232.
Specification of
Application filed February 23To all whom it may concern:
Be it known that I, McDUFFEE BRADFORD, a citizen
of the United States, residing at Nocona, in the county
of Montague and State of Texas, have invented certain
5 new and useful Improvements in Gin-Saw Cleaners, of
which the following is a specification.
The present invention appertains to means for remov-
ing gum and otherwise cleaning the'saws of a cotton gin
so as to maintain the latter in prime working condition,
10 said cleaner also serving to straighten the teeth of the
saws during the process of removing foreign matter
therefrom.
For a full description of the invention and the merits
thereof and also to acquire a knowledge of the details of
15 construction and the means for effecting the result, ref-
erence is to be had to the following description and ac-
companying drawings.
While the invention may be adapted to different
forms and conditions by changes in the structure and
20 minor details without departing from the spirit or essen-
tial features thereof, still the preferred embodiment is
shown in the accompanying drawings, in which:
Figure 1 is a front view of a cotton gin embodying the
invention. Fig. 2 is a detail view of the cleaner. Fig.
25 3 is a sectional view of a portion of the cleaner and the
fastening means therefor.
Corresponding and like parts are referred to in the fol-
lowing description and indicated in all the views of the
drawings by the same reference characters..
*30 The invention is adaptable to any type or make of
cotton gin and when in position may be instantly
thrown into, or out of operation as may be required, it
being understood that when the cleaner is out of action,
the gin saws are run to the right, or forward, and when
35 it is required to clean the saws, the latter are rotated
backward and at this time, the cleaner is thrown into
operative position.
The cotton gin illustrated is of ordinary construction
being selected to demonstrate the application of the in-
40 vention. The numeral 1 designates the shaft upon
which the gang of saws 2 are mounted, said shaft being
provided with band pulleys 3 and 4, the former being
driven so as to rotate the saws forward and the latter
adapted to have power applied thereto for rotating the
45 saws backward when it is required to clean the same.
The pulley 4 is somewhat smaller than the pulley 3 and
may be applied to either end of the shaft 1, and as illus-
trated is usually secured to the end of the shaft oppositeLetters Patent. Patented Sept. 3, 1907.

to that provided with the pulley 3, the shaft 1 being
capped to admit of the pulley 4 being readily fitted 50
thereto, or removed therefrom.
The cleaner consists of a plate 5 having teeth 6 along
one edge, viz: the upper edge, said teeth being prefer-
ably an integral part of the plate and extended a short
distance into the spaces formed between adjacent saws. 55
The plate 5 is provided with slots 7 through which pro-
jections 8 pass to secure the plate in position and limit
its movements. The plate 5 is preferably of metal such
as steel and its upper edge is cut to provide the teeth 6.
A pin 9 projects outward from the plate 5 and extends 60
into the fork 10 provided at the. upper end of shipper
lever 11 pivoted to the frame of the cotton gin at 12 and
provided as convenient means for moving the plate to
bring the teeth into engagement with one side or the
other of the saws 2. 65
The shipper lever 11 is conveniently positioned being
preferably located intermediate the ends of the plate 5
and having its lower end extended so as to be conven-
iently grasped when it is required to throw the cleaner
into or out of operative position. When the gin is in 70
operation, the teeth 6 of the cleaner occupy a neutral
position between the saws, but when it is required to re-
move the gum or other matter adhering to the saws, the
latter are rotated backward by the application of power
to the pulley 4 and at the same time the lever 11 is 75
moved to bring the teeth 6 into engagement with one
side or the other of the saws to effect cleaning thereof.
Should any of the saw teeth be bent out of line, the
teeth of the cleaner coming in contact therewith. will
straighten, or aline, the bent teeth and thereby simulta- 80
neously with the cleaning operation effect an alining, or
straightening of the teeth of the gin saws.
The cleaner is adjustably connected to the frame of
the gin by means of plates 19, the latter having projec-
tions 8 near one end which enter the slots 7 of the plate 85
5, and being provided near its opposite end with slots 20
through which bolts 21, or like fastenings pass, so as to
adjustably connect the plates 19 with the frame of the
machine. The teeth 6 of the cleaner may be projected
into the spaces between the saws 2 more or less by lon- 90
gitudinal adjustment of the plates 19, the latter being
secured in adjusted position by re-tightening the bolts
or fastenings 21.
A crank may be fitted to the shaft 1 in any manner as
indicated at 13 in Fig. 1 for rotating the saws backward 95
when it is required to clean the same.
