JAMES Y. HUGHES, OF QUANAH, TEXAS.
COTTON-SEPARATOR.Specification of Letters Patent.
Patented Sept. 7, 1915.
Application filed May 3, 1910. Serial No. 559,075. Renewed August 2, 1915. Serial No. 43,347.
To all whom it may concern:
Be it known that I, JAMES Y. HUGHES, a
citizen of the United States, residing at
Quanah, in the county of Hardeman and
5 State of Texas, have invented new and use-
ful Improvements in Cotton-Separators, of
which the following is a specification.
My invention relates to apparatus for
cleaning : eed cotton and separating the dust
10 and dirt therefrom prior to the ginning op-
eration.
Prior to my invention, there have been de-
vices manufactured for the purpose of clean-
ing seed cotton, in some of which revolving:
15 screens or sieves have been used to separate
the dust in connection with revolving blades
or blower attachments.
It is my purpose to improve upon all such
prior devices with which I am aware, and
20 to overcome the difficulties which have been
encountered in using such cotton separators.
My invention will be better understood
from the following description in connec-
tion with the accompanying drawings, in
25 which-
Figure 1 is a vertical cross-section of an
apparattbs embodying my invention; and
Fig. 2 is a longitudinal section on the line
II-II of Fig. 1.
30 The cleaning apparatus comprises a main
casing 1, divided by a vertical partition 2
having a plane unobstructed front face into
two compartments, 3 and 4. A seed-cotton
conveyer-flue 6, leads into the cotton sepa-
35 rator compartment 3, and an exhaust or suc-
tion pipe 7, in alinement with the flue 6,
leads from the opposite wall of the dust
compartment 4 and is connected to a suit-
able blower or suction-pump. The lower
40 part of compartment 3 terminates in a chute
8, preferably located directly over the belt-
distributer 9, which conveys the cotton to
the discharge hoppers 10 and 11, of the cot-
ton gins. The compartment 4 has a closed
45 bottom 12, which is preferably hinged as
shown, for the removal of any dirt that may
accumulate therein.
Revolubly mounted in a circular aperture
in the partition 2, is a perforated separating
50 wheel 14 having a plane unobstructed oper-
ating face, which may be rotated in any suit-
able manner, as by gearing connected with
a shaft of the belt-distributer as shown in
Fig. 1.. It will be observed that the upper
55 portion of this reticulated wheel is a direct
line between the conveyer-flue 6, and the suc-tion-pipe 7, so that there will be a strong
air-blast across the top portion of the wheel,
while the lower portion will move in a prac-
tically de:id-air-space. The result of this 60
arrangement is to cause the seed-cotton
forced through the conveyer-flue 6, to strike
against the upper part of the revolving per-
forated wheel and to be held there by the
strong suction from the pipe 7 directly op- 65
posit.. The strong air-blast against the cot-
ton as it is suddenly arrested against the
perforated wheel will effectually drive out
the dust and dirt, most of which will be
carried through the chamber 4 and into the 70
suction-pipe 7 with the exhaust, some of the
heavier particles falling down into the dead-
space in the bottom of the chamber. As the
wheel 14 revolves, the cotton adheres to it
until it is carried down into the lower por- 75
tion of chamber 3, where there is practically
no suction, the cotton being there thrown off
by centrifugal force and gravity upon the
distributing belt 9.
The construction and arrangement of my 80
separator wheel have a number of decided
advantages over the prior devices. In such
devices with which I am familiar, the sepa-
rator, whether stationary or revoluble, con-
sists of a wire sieve, which causes great 85
difficulty by reason of the wire meshes be-
coming clogged, the cotton entering the in-
terstices and clinging tenaciously thereto.
I have overcome this difficulty by employing
a perforated metal disk or wheel, having a 90
reticulated plane smooth surface from which
the cotton readily slides off as soon as the
suction ceases.
For the purpose of overcoming some of
the difficulties encountered in the use of 95
screens of wire-mesh, it has been proposed to
provide the revoluble separator with vanes
or blades. These, however, interfere with
the free circulation of air in front of the
separator wheel, which I have found to be 100
essential, and also cause some injury to the
cotton fiber by their impact. On the other
hand, the smooth plane surface of my sepa-
rator wheel causes no injury whatever to
the cotton, and the entire surface is freely 105
exposed and unobstructed. I wish also to
call attention to another important advan-
tage possessed by my arrangement. It will
be observed that .the separator wheel is in
the plane of movement of the distributed 110
belt and that adjacent portions of the wheel
and belt revolve in the same direction, so1,153,180.
