siderable angle to prevent the cotton from
webbing or sticking. The cotton passes in
close contact with the screening means, so
that its thorough cleaning is assured.
z The cotton-cleaning screen 14 is represent-
ed as consisting of a' plurality of elongated
slats spaced to provide therebetween slots,
and as the cotton passes over these slots
sticks, nails, bolts, and screws that cannot
. o ordinarily be removed from the cotton will
pass through the slots.
The cotton dropper or cleaner need not
necessarily be used in connection with a stor-
age-house, although its use in such connec-
t5 tion is advantageous for the reason hereinbe-
fore set forth. It may be employed success-
fully to drop cotton onto a belt distributer or
anything of an equivalent nature.
The cleaned cotton passes by gravity from
20 off the screen 14 into the tube 18 and from
thence into a chute, as 23. It will be seen
that the cleaning-screen 14 is arranged at a
steep angle in order to insure the cotton pass-
ing by its own weight from off the same and
25 from thence into the tube and chute just al-
luded to for delivery by the chute to any one
of the bins 3. I rely, therefore, simply upon
gravity to cause the conduct of the cotton
from the cleaning-screen to' any one of the
3o bins.
The chute is movably mounted, so that it
can be shifted to direct the cleaned cotton
into any one of the series of bins 3. In the
present case the chute is revolubly mounted,
35 it being supported for turning motion in some
suitable manner by the pendent tube 18. To
uphold the chute in a substantial manner, it
may be provided with an antifriction-wheel
24 near its free end to travel upon the annu-
40 lar track 25, supported by suitable frame-
work in the house 2 above the bins. Ex-,
tending downward from the head of the chute
23 is an elongated spindle 26, having a hand-
wheel or analogous actuating device, as 27,
45 at its lower end. The hand-wheel is arranged
in proximity to the floor of the storage-house,
so that it can be readily reached by a person
standing upon said floor in order to turn the
chute 23. The spindle 26 is coaxial with the
5o chute 23, and it will be evident that when it
is turned the chute can be revolved.
The apparatus hereinbefore described is
simple in construction, effective in operation,
and thoroughly cleanses the cotton and dis-
55 poses of it when cleaned in a satisfactory
manner, while at the same time means are.
provided for carrying out the trash from the
building. I am enabled to operate the force-
feeder without the use of belting or analogous
6o mechanical devices. It will be understood'
that the curved surfaces of the two boards or
guards 12 and 15 are concentric 'with the
force-feeder 8. They, in connection with
two oppositely-disposed blades 10, with the
65 flexible strips 11 on the latter, serve, in effect,to divide the interior of the casing into two
chambers, the upper one being a suction-
chamber, while there is no suction in the
lower chamber. The cleaned cotton is deliv-
ered into this lower chamber, and as there is 70
no suction in the same there is no possibility
of the cleaned cotton being drawn up into the
upper portion of the casing.
It will be understood that when the cotton
strikes the screen 13 it does so with consider- 75
able force, and in this way I am enabled in-
itially to remove foreign matter from the
mass, which passes through the meshes pf
said screen and out into the suction-pipe 7.
In practice I prefer to arrange a sliding 8o
cut-off, as 16a, between the hopper 16 and
discharge-pipe 17, which may be closed or
open, as desired, as in neither case will the
action of the apparatus be affected.
The disks 9 are overlapped exteriorly and 85
marginally by flexible strips which cover the
joints between the disks and casing in an
air-tight manner. The strips are denoted by
9a and may be of any form, although they or-
dinarily are annular. 90
The annularly-arranged bins 3 surround
an open space 3a, (shown as circular,) a pas-
sage-way or aisle 3b leading into the said
open space 3a at a point outside of the bin.
An attendant can enter the open circular 95
space 3- by way of the passage-way or aisle
3', so as to obtain access to the hand-wheel
27, located in said circular open space.
Having thus described the invention, what
I claim is- 100
1. In a cotton-handling apparatus, a cas-
ing, a pneumatic conveyer opening into the
casing, a suction-flue, and a discharge-chute
for cleaned cotton, leading from the casing,
a screen between the conveyer and the suc- 105
tion-flue, a cleaning-screen between the suc-
tion-flue and the discharge-chute, for screen-
ing the cotton before it reaches said chute,
and a force-feeder in the casing to positively
move the cotton from the conveyer to the '10
cleaning-screen and operable solely by the
blast of air entering the casing from said
pneumatic conveyer.
2. In a cotton-handling apparatus, a cas-
ing, a pneumatic conveyer opening into the !15
casing, a suction-flue, and a discharge-chute
for cleaned cotton, leading from the casing,
a screen between the conveyer and the suc-
tion-flue, a cleaning-screen between the suc-
tion-flue and the discharge-chute, for-screen- 120
ing the cotton before it reaches said chute,
and a force-feeder in the casing, arranged to
be operated solely by the blast of air entering
the casing from said pneumatic conveyer and
comprising a plurality of blades. 125
3. In a cotton-handling apparatus, a cas-
ing, a pneumatic conveyer opening into. the
casing, a suction-flue, and a discharge-chute
for cleaned cotton, leading from the casing,
a screen between the conveyer and the sue- 130
