tion and conveyor pipes 10 and 11 by any
suitable current generator (not shown).
In actual use, these pipes will usually be
united into a common pipe with a suction
5 fan, of conventional form. located therein.
The arcuate free ends of the flues 12 are
open at each side, and the air suction there-
through draws the air through the perfora-
tions of the disks 9 on each side.
10 Seed cotton is delivered to the transverse
apron 14, arranged above and behind the
disks, and is delivered from it through the
spaced hoppers 15 to the disks. These hop-
pers are arranged alternately, with respect
15 to the suction flues 12, and oppositely, with
respect to the chutes 13 and through them
the seed cotton is fed into the disk spaces
between the suction flues 12: The shaft 8
has a pulley 16 fixed thereon, through which
20 rotation is imparted to said'shaft, and the
disks, carried thereby, in the direction iidi-
cated by the arrows, in Figures 4 and 5.
The cotton is held against the sides of the
disks, between which it is fed, by the suction
25 of the air, through the perforations thereof,
and is carried by said disks against the
blades 17, located between said disks. These
blades project between said disks and their
edges fit closely against the inner sides of
30 the adjacent disks. Said sides of said disks
are provided with radiating arcuate grooves
18, which engage with the cotton and tend
to force it outwardly to distribute it along
the full length of the blades to provide for
35 the maximum stripping effect thereof. The
blades 17 are supported by a transverse bar
19, whose ends are formed with depending
arms 20, 20, whose lower ends are pivoted
to the front legs 3 and 4. The upper ends
40 of these arms have aligned circular openings
21, 21, through which the shaft 22 extends.
This shaft is mounted in the aligned bear-
ings 23, 24 and 25, carried by the framework
and has ecentrics 26 carried thereby and
45 located in the openings 21. The shaft 22
has a pulley 27 fixed thereon in alignment
with a pulley 28, fixed on the shaft 8, and a
belt 29 operates over said pulleys and trans-
mits rotation from the latter to the former,
50 and the shaft 22 is thereby rotated.. The
rotation of the shaft 22 operates, through
the eccentrics 26, to oscillate the arms 20, 20
and the blades 17, carried thereby, the oscil-
lation of the blades rendering them more
55 efficient in stripping the lint from 'the seed
and preventing the congestion of the cotton
against them.
The blades rest upon the supporting fin-
gers 30, spaced apart and formed integrally
60 with the bar 19 and are clamped thereon by
means of caps 31, triangular in cross section,
and secured in place by' means of bolts 32,
32, which pass through said caps and blades
and are tapped into the fingers under-
65 neath. As the edges of the blades becomeworn, causing oo much clearance, it becomes
necessary to adjust them and to provide for
this adjustment the blades are formed of -
lengthwise sections. The sections have the
inside- opposing notches 33, 33 forming 70
openings through which the bolts 32, 32 pass
and said notches are formed with the front
sloping sides 34, 34, which- diverge. Op-
posite the outer ends of the blades the bar
19 has the upstanding ears 35, through which 75
the set bolts 36 are threaded and the inner
ends of these bolts rest against -the plates
38, which in turn rest against the outer ends
of the corresponding blades. When the
edges of the blades wear, causing too much- 80
clearance between them and the disks, the
bolts 32, 32 may be -loosened and the -set
bolts screwed against the plates 38, which
will force the blades inwardly, and the slop- -
ing sides 34 of the openings 33, acting 85
against the bolts 32 will cause the .blade sec-
tions to spread apart until the desired clear-
ance is attained and -the bolts 32, 32 then
tightened, clamping said. sections in fixed
position. 90
As above stated, the cotton fed between
the stripper disks is held by air suction
against the sides of the disks and carried by
them against the edges of the blades, by
which the seed are arrested and- the lint 95
passes on between the disks and the blade
edges, the lint being stripped from the.seed
by the combined action of the disks and
oscillating blades. During this operation,
.the seed work out along the sides of the caps 100
31 in the troughs formed by the sloping
sides of said caps and the adjacent disks and
when freed of the lint they are no longer
subject to the. air-suction, and pass over the
dade bar 19 into a suitable receptacle pro- 105
vided for them.
The free ends of the delivery chutes 13
are provided with side slots 39, 39 through
which the lint enters into said:chutes. These
inlets, as 'is obvious, are restricted, to in- 110
crease the force of the suction to insure:the
entrance of the lint therein. After the lint
is carried by the disks past the ends of the
suction flues 12 it passes beyond the range
of the suction through the disk perfora- 115
tions and comes within range of the suction
through the chutes 13 and is free to enter
into said chutes through which it is car-
ried into the' conveyor pipe,' and any lint
which may be drawn through the perfora- 120
tions of the disks passes through the flues 12
into the suction pipe, and- said lint is then
conveyed by said pipes, by- suction, to the
condenser.
As stated, the sections 10' and 11' are 125
rotatable' so that the flues 12-and -chutes 13
may be withdrawn from between the disks
9, as shown in dotted lines, in Figure 4,
thus making provision for gaining access to-
the disks for repairing or cleaning the same. 1300
