EDWARD L. HUNTSMAN, OF ROCHESTER, TEXAS.
COTTON-GIN.1,229,084.
Specification of Letters Patent.
Patented June 5, 1917.
Application filed June 19, 1916. Serial No. 104,541.
To all whom it may concern:
Be it known that I, EDWARD L. HUNTS-
MAN, a citizen of the United States, resid-
ing at Rochester, in the county of Haskell
5 and State of Texas, have invented certain
useful Improvements in Cotton-Gins, of
which the following is a specification, ref-
erence being had therein to the accompany-
ing drawing.
10 This invention relates to improvements
in cotton gins, one object of the invention
being the provision of an attachment for
a gin feeder to separate cotton from the
burs during the gin operation, the same
15 being especially adapted for use upon. cot-
ton containing an excess amount of bolls.
A further object of the present invention
is the provision of an air suction device
whereby the cotton will be removed from
20 the burs before its entrance into the gin
instead of carrying to the huller breast the
cotton and burs together.
A still further object of this invention
is the provision of a simple and com-
25 paratively inexpensive mechanism which is
adapted to dispense with the cotton sliding
board used in cleaner feeders for cotton
and which will operate to separate the cot-
ton from the burs or bolls before the en-
30 trance thereof upon the gin stand or huller
breast.
In the accompanying drawings;-.
Figure 1 is a side elevation of a cleaner
feeder with the present attachment in use,
35 such attachment being shown in section to
illustrate the various positions of the parts.
Fig. 2 is a top plan view thereof.
Fig. 3 is a view on an enlarged scale
of the present attachment showing by ar-
40 rows and spears the directions of travel of
the cotton and burs.
Figs. 4 and 5 are detailed views of vari-
ous parts.
Referring to the drawings, the numeral
45 10 designates the cleaner feeder mechanism
which is of any preferred form, the present
separating attachment 11 being introduced
in lieu of the usual cotton sliding board
applied in connection with a cleaner feeder.
50 This attachment consists of a casing 12
which has mounted therein a slanting par-
tition 12' for dividing the casing into an
upper compartment and a lower compart-
ment in the latter of which is mounted forrotation a saw cylinder 13 which is prefer- 55
ably eight inches in diameter, coarse teeth
preferably six to the inch. Disposed
throughout the width of the opening 14
in the partition which establishes communi-
cation between the upper and lower com- 60
partments are the ribs 15, while extending
from each side of the casing 12 is a suction
pipe 16 which leads to the reduced four-
inch flue 17. Thus, a suction of air through
the pipe also passes through the ribs and 65
draws the cotton so that it will adhere to
the cylinder 13 to be pulled off the saw by
the suction and to lodge against the per-
forated plate 18.
The roller 19 is substantially six inches 70
in diameter and is provided with the elas-
tic or rubber belt flaps 20 .which serve to
direct the action of the suction to the top
of the cylinder and which clean the cotton
from the perforated plate and direct it 75
down the lower compartment which is ar-
ranged in communication with the top of the
cotton roll chamber 21' of the gin stand 22.
An arcuate shield 21 extends from the
partition 14 and is positioned beneath the 80
cylinder 13 terminating short of the roller
19 so as to prevent the action of the suction
of air on the under surface of the cylinder.
A slatted belt 23 which is the exact width
of the feeder is provided with a plurality 85
of short spikes or pins 24 to receive and
rake the burs from the ribs and cause them
to move down partition 12' into the huller
breast 25 of the gin stand with which the
upper compartment is arranged in com- 90
munication, the upper end of the upper
compartment being incidentally arranged
in communication with the outlet of the
feeder 10.
It will thus be seen that with this attach- 95
ment the cotton will be completely sepa-
rated from the burs as it passes through
the regular gin stand feeder to the gin
stand and that the cotton thus cleaned will
be fed direct into the cotton roll so that 100
the burs are separated and are disposed of
in the same manner as with - the regular
double breast gin stand.
With this attachment by the aid of the
suction all small locks of cotton are saved 105
and ginned and by separating the larger
percentage of the cotton fiber from the burs
at this operation, the operator can maintain
