JAMES M. SHEPPARD, OF CROWELL, TEXAS.
COTTON-CLEANER AND GIN-FEEDER.No. 898,072.
To all whom it may concern:
Be it known that I, JAMES M. SHEPPARD, a
citizen of the United States, residing at
Crowell, in the county of Foard and State of
5 Texas, have invented a new and useful Cot-
ton-Cleaner and Gin-Feeder, of which the
following is a specification.
This invention relates to cotton cleaners to
be employed in advance of cotton gins and
10 like machines, and has for its principal ob-
ject to provide a novel form of device for re-
moving the impurities from the cotton and
delivering the same at a uniform rate of
speed and in uniform quantity to the gin.
15 A further object of the invention is to pro-
vide a mechanism of this type in which a rev-
oluble screen is employed to receive the cot-
ton to be cleaned, the cotton being allowed to
accumulate on but a small portion of the
20 outer surface of the screen drum, and the im-
purities being drawn through the screen by
suction while the clean cotton is delivered
from the screen.to the gi.
A still further object of the invention is to
25 provide a revoluble screen drum, the periph-
ery of which is mounted in two separate com-
partments, one of which receives the cotton
to be cleaned, while the other communicates
with an air exhausting means, care being
30 taken to prevent communication between
the chambers except through the meshes of
the screen.
A still further object of the invention is to
provide an apparatus of this class in which a
35 series of cleaners are employed, all fed from a
common source, the feeders being so arranged
that any one or more may be stopped in case
the gin or gins which it supplies are stopped,
while the others continue in operation.
40 A still further object of the invention is to
provide means whereby a quantity of cotton
may be accumulated in advance of each
cleaner which is stopped, so that when the
cleaner is again started into operation, there
45 will be a mass of cotton ready to supply it.
A still further object of the invention is to
provide a cotton accumulating means which
will insure the retention of approximatelyI
the same quantity of cotton at each stop-
50 page of the machine without regard to the
length of time for which the machine is out
of operation.
With these and other objects in view, as
will more fully hereinafter appear, the inven-Patented Sept. 8, 1908.
tion consists in certain novel features of con- 55
struction and arrangement of parts, hereinaf-
ter fully described, illustrated in the accom-
panying drawings, and particularly pointed
out in the appended claims, it being under-
tood that various changes in the form, pro- 60
portions, size and minor details of the struc-
ture may be made without departing from
the spirit or sacrificing any of the advantages
of the invention.
In the accompanying drawings:-Figure 1 65
is a front elevation, partly in section of a
cotton cleaning and gin feeding apparatus
constructed in accordance with the inven-
tion. Fig. 2 is a sectional elevation through
one of the feeders on the line 2-2 of Fig. 1, 70
the view being on an enlarged scale. Fig. 3
is a view similar to Fig. 2, illustrating a modi-
fication. Fig. 4 is a detail view showing the
arrangement of the valves and their connec-
tions. Fig. 5 is a view corresponding to 75
Fig. 2 illustrating a modification.
Similar numerals of reference are em-
ployed to indicate corresponding parts
throughout the several figures of the draw-
ings. 80
The apparatus as at present shown is de-
signed for use in connection with three sepa-
rate gins, as A, B and C, the number of gins,
and the number of cleaners used being im-
material, and the construction being such 85
that additional gins and feeders may be
added from time to time, as required.
Mounted above, and in alinement with
each gin is a feeder and cleaner, to which the
cotton is supplied through an inlet pipe 10 90
from the wagon or other source of supply, the
cotton entering in a horizontal line over the
tops of the feeders, and being fed along by a
current of air which is induced through the
pipe 10 by suction force exerted through a 95
discharge pipe 11 at the opposite end of the
apparatus, this pipe 11 being connected in
any suitable manner by a suction fan or like
machine.
Above each gin are two frames 15, said 100
frames serving as bearings for a horizontally
disposed shaft 16, and each shaft carries
spoked disks 17 to which are secured cylin-
drical screens 18. The cylindrical screen
drum is surrounded by a cylindrical casing 105
20 that is concentric with the periphery of
the drum and extending across the annular
space between the casing and the screen is aSpecification of Letters Patent.
