Improvement in Machines for Cleaning or Delinting Cotton Seed.
I, JAMES STINAT COCHRAN, of 10th Street and Columbia Avenue, Philadelphia,
Pennsylvania, United States of America, Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to machines for cleaning or delinting cotton seed, the several
features thereof being hereinafter fully set forth.
In the accompanying drawing
Figure 1 represents a partial side elevation and partial vertical section of two
machines for cleaning or delinting cotton seed, embodying my invention.
Figure 2 represents a top plan view of one of the machines and connected parts.
Figure 3 represents a side elevation of the machine shown in Figure 2, showing.
parts of the same in section.
Figure 4 represents a side elevation of the brush of the machine, part of the same
being separated.
Figure 5 shows a side elevation of a connected series of machines.
Similar letters of reference indicate corresponding parts in the several figures.
A designates the frame of the machine, and B designates a conical casing which is
mounted therein, and having within the same the brush C, the latter consisting of a
cone-shaped backing D, with brush material thereon, said material being formed of
a strip E of leather or other suitable material with wires or teeth F attached thereto,
the strip being wrapped around the backing and fastened by a wire cord G, which is
wound spirally around the strip in the spaces between the wires or teeth' thereof, and
secured at its ends by staples G', as shown in Figure 4, which are driven through the
strip into the backing and embracing the wire, the strip thus being most firmly bound
to the backing, and securely held thereon.
H designates a feed or supply box, which is located adjacent to the casing C, and
into the same dips the endless conveyor J, which is supported on'a suitable frame K,
and is operated by a wheel or pulley K¹, shown in dotted lines, Figures 2 and 3, to
which power is suitably communicated.
The buckets L of the conveyor discharge into a chute M, which is located above the
casing C, and communicates with feed openings N in the top of said casing, whereby
the latter may be supplied with seed to be cleaned or delinted.
The casing B has a hinged door P, whereby access is had to the interior of said
casing and the brush, it being noticed that the inner surface of the casing is clad' with
brush material Q, preferably wire.
The brush C is rotated in any suitable manner, it being noticed that in the drawings,
its shaft is mounted on the frame A, and carries a pulley C¹, for rotating said
brush.
When the machine is in operation, the seed is carried from the box H, by the
conveyor J, to the chute or receptacle M, and thus directed through the openings N
into the casing B, where it is subjected to the brush therein, and thus cleaned or
delinted.
Below the brush is a box R, within which is a chute or deflector S, the said box
heing in coinmunication with the open bottom of the casing B.
The box R opens into a seed box or receiver T, into which dips the endless conveyor U
of any preferred construction, and consisting in this instance of buckets R' attached
to flexible side supports R2, passing over rollers, pulleys or sprocket wheels T', and
said buckets discharge into an elevated conveyor V. The box R has connected with
it a funnel W, which leads to a blower or exhaust fan X, from which leads a discharge
pipe Y.

page_text: It will now be seen that as the seed cleaned or delinted leaves the brush, and falls
through the opening in the bottom of the casing, it is directed by the chute S into the
box R, and drops into the receiver T, after which it is taken up by the conveyor U,
and deposited into the conveyor V, said conveyor V, which may be of any preferred
construction, and operated as may be desired, being shown as composed of flexible
side supports V2, passing around pulleys, rollers or sprocket wheels V³, and carrying
floats V
Simultaneously therewith the blower or fan X draws the lint from the casing B,
through the box R, and funnel W, and directs the same into the pipe Y, by which it
may be discharged elsewhere.
It is important to employ large volumes of air, in order to effect the proper
discharge of the lint from the casing. For this purpose, I form in the top of the
casing, inlets Z, in the side of the funnel W, an inlet Z, and in the side of the box R,
an inlet 22, so that air may be drawn into and through said casing, box and funnel,
and thus effectively carry away the lint through the blower or fan.
The vent or inlet Z', in funnel W, is provided with a movable cover Z³, and may be
opened or closed, to compensate for variations in barometric pressure. When the
pressure is high, the said vent is opened to prevent upward suction of the seed with
the lint, and when the pressure is low, the vent or inlet is closed, to establish sufficient
suction to raise the lint.
The inlets are preferably guarded by gauze or netting, to prevent the entrance of
improper matter into the casing B.
The fan X, Figure 1, aids in blowing the lint from the seed passing over the
chute S, by directing a blast thereon, through the opening in the bottom of the
casing B.
In Figure 1, I show a duplication of the machine, the seed passing through first
one machine and then the other, and in Figure 5, a triplication of the same.
When a battery of three machines is used, the seed is placed in the first two
machines and delinted, and the cleaned seed therefrom unitedly delivered into the
third machine, by being deposited on the conveyor V from said 1st. and 2nd. machines,
and from said conveyor V, being carried by chute V leading to the seed receiving
box H, of the third machine, where the delinted seed is further subjected to a cleaning
action.
If desired, the seed may be placed in the first machine, and successively cleaned in
the remaining machines composing the battery.
In practice, the brush of the first machine is somewhat coarser than those of the
other machines of the series or team, so that the cleaning or delinting may be gradually
accomplished.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
1st. A brush for delinting or cleaning cotton seed, composed of a backing or body
having wound thereon a strip of card or brush clothing, composed of a backing
provided with wires or teeth inserted therein, and having said strip bound to the
backing by a cord or wire wound upon the same, and lying between the teeth, substan-
tially as described.
2nd. A machine for delinting or cleaning cotton seed, consisting of a casing with a
brush on the inner surface thereof, and a revolving brush within the same, said
revolving brush consisting of a body, a strip of toothed material wound thereon, and
a binding wire or cord wound upon said strip, and secured to said body, substantially
as described.
3rd. A machine for delinting or cleaning cotton seed having a revolving brush
consisting of a conical body, a strip of toothed material wound thereon, and a binding
wire or cord wound upon said strip, and secured to said body, and a casing conforming
to said brush, and having an inner brush surface, substantially as described.
4th. An organized machine for delinting or cleaning cotton seed, having a casing

page_text: with a brush therein, a box for receiving the cleansed seed. and a funnel or pipe
leading from said box to a blower or fan, said casing, box and funnel having air inlets,
substantially as described.
5th. A battery of machines for delinting or cleaning cotton seed, each having a
casing with a brush within the same, a seed receiving box and a suction funnel or
pipe leading from said box, said casing, box and funnel having air inlets, an elevator
leading from the seed discharge box of one machine, and a conveyor receiving the
seed from said elevator, and leading to a feed opening of another machine, substan-
tially as described.
