frame 34 extends approximately one half
the distance around the wheel 8 so that the
air pockets in the wheel 8 will be closed
while they are passing the frame 34. The
5 wheel 8 is provided with flexible flashings 32
secured thereon by metal strips 33 for mak-
ing an air-tight closure when passing the
circular frame 34. Circular strips 31 are
attached to the upper and lower edges of the
10 ends of the spokes or partitions 10 for mak-
ing these partitions rigid relative to each
other and to the disks 30. Fig. 4 illustrates
the construction of the wheel 8. A hopper
35 is provided to hold the cotton on the mov-
15 ing and exposed portion of the screen 13 on
wheel 8. A screened moving surface is thus
provided to move under a hulling device.
This screened wheel has compartments or
pockets which are made to pass under the
20 hulling device and the wheel 8 is driven
by the shaft 4 which is driven by the drive
pulley wheel 20.
Various changes may be made in the con-
struction of this machine without departing
25 from the purpose of this invention, the es-
sential feature of which is to pass a screened
compartment under a hull extractor while
pneumatic pressure is utilized to hold the
cotton down on the screen..
30 What I claim is,-
1. A hull extractor comprising a frame
and a casing supported thereby, a hull ex-
tracting device, a cotton carrying member
having a plurality of screened compartments
35 moving under said hull extracting device,
means for delivering cotton to said carrying
member and means for removing cleaned
cotton therefrom, and a suction pipe con-
nected to said frame in a position to exert
40 pressure through each compartment on the
cotton carried by said carrying member as
each compartment is passing and remains in
communication with said suction pipe.
2. A hull extractor comprising a frame
45 and a casing supported thereby, a hull ex-
tracting device, a cotton carrying member
having a plurality of screened compartments
moving under said hull extracting device,
means for delivering cotton to said carrying
50 member and means for removing cleaned
cotton therefrom, and means for directing
pneumatic pressure on the cotton while pass-
ing under said hull extracting device.
3. A hull extractor comprising a frame
55 and a casing supported thereby, a hull ex-
tracting device, a cotton carrying wheel
having a plurality of screened compartments
journaled in said frame within said casingand moving under said hull extracting de-
vice, means for directing pneumatic pressure 60
on cotton carried by said wheel while pass-
ing under said hull extracting device, and
means for driving said hull extracting de-
vice.
4. A hull extractor comprising a frame 65
and a casing supported thereby, a revolving
hull extracting device, a cotton carrying
wheel having a plurality of screened com-
partments journaled in said frame and mov-
ing under said hull extracting device, means 70
for delivering cotton to said screened com-
partments, and a suction pipe connected to
said frame for directing pneumatic pressure
on the cotton carried by said wheel when-
ever a compartment is passing said suction 75
pipe.
5. A hull extractor comprising a frame
and a casing supported thereby, a revolving
hull extracting device, a rotating cotton car-
rying member having a plurality of screened 80
compartments journaled in said frame with-
in said casing and moving under said hull
extracting device, said casing having por-
tions thereof cut away for delivering cotton
to and removing cotton from said carrying 85
member, and a suction pipe connected to
said frame for directing pneumatic pressure
on the cotton while the cotton is passing un-
der said hull extracting device, each com-
partment remaining in communication with 90
said suction pipe while the cotton on the
surface of the compartment is passing under
said extracting device.
6. A hull extractor comprising a frame
and casing supported thereby, a revolving 95
hull extracting device, a cotton carrying
member having a plurality of screened com-
partments moving under said hull extract-
ing device, means for delivering cotton to
said carrying member, means for directing 100
pneumatic pressure on the cotton while pass-
ing under said hull extracting device, a suc-
tion pipe connected to said casing for re-
moving cleaned cotton from said carrying
member, and means for sealing each com- 105
apartment approximately air - tight while
passing said suction pipe except through
said suction pipe.
In testimony whereof, I set my hand in
the presence of two witnesses, this 16th day 110
of November, 1912.
