COMPLETE SPECIFICATION
Improvements in Apparatus for Removing Lint from Cotton Seed.
1, ROBERT FERRIDAY SPANGENBERG, of 171 Antonine Street New Orleans, in the
county of Orleans, and State of Louisiana, United States of America, cotton broker,
do hereby declare the nature of my invention for "IMPROVEMENTS IN APPARATUS FOR
REMOVING LINT FROM COTTON SEED," 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 an improvement in a delinter oi lint remover for cotton seed,
in which an adjustable shaft with discs, fans, and arms adjusted thereon, are made to
operate in conjunction with a series of hoppers, brushes, and condensers, and the objects
of my improvements are to remove the lint fi om the seed without breaking, or injuring
the fibre of cotton, or the seed either by friction or abrasion, to grade the lint, and
to thoroughly polish the seed after the lint has been removed. I attain these objects
by the mechanism illustrated in the accompanying drawings, in which,
Figure 1 is a vertical sectional view of my delinter and condenser.
Figure 2 is a sectional top view of my delinter, showing the brushes in position.
Figure 3 is a sectional front view of my condenser
Similar letters and numbers refer to similar paits throughout the several views
In constructing my delinter a shaft as designated by A, is placed in position as
shown in Figure 1, the lower end of same revolves in a bearing as shown by R, and
by means of set screw Q, the shaft may be raised or lowered. upon shaft A, I adjust
disk H, which is four feet in diameter, and has upon its top plane a carding surface
of metal teeth which are one eighth of an inch in length, and are placed in a vertical
position I also place upon a shaft, and in close proximity to disk H, a fan with
concave blades as shown by M, in Figure 1, said fan is enclosed in a casing as shown
by L, with inlets in casing as designated by 12, and with an outlet 1 which connects
with condenser chamber 4. The cross frame Z, is fastened within the casing 10 at a
sufficient distance from disk H, to allow the seed to pass freely under it, and resting
Just over its central opening is placed a hopper, as shown by B, in Figure 1, and
dotted lines in Figure 2: on end of shaft A, and within hoppers B, C, and D are
four or more arms N, which act as a feed or conveyer, and causes seed to be distri-
buted to the disk H, I and K, as shaft A rotates in close proximity to arms N, and
centre of disks attached to frame Z, are a series of six radial projections 11, which
rest under hoppers B, C and D on shaft A is also adjusted disk I, which is about
the same diameter as disk H, and has upon its top plane a carding surface of metal
teeth which are one sixteenth of an inch in length, and which are also placed in a
vertical position, in close proximity to disk I, a fan with concave blades as shown by
DI, is placed upon said shaft, said fan also being enclosed in a casing as shown by L,
with inlets in casing as designated by 12, and with an outlet 2, which connects with
condenser chamber 5, I also attach to shaft A disk K, which is of same dimensions
as H, and I, and has upon its top plane a brushing, or polishing surface of bristles
made from casings, and of sufficient length to thoroughly polish the seed after the lint
has been removed; in close proximity to disk K, a fan with concave blades as shown
by M, is placed upon said shaft, said fan also being enclosed in a casing as shown
by L, with inlets in casing as designated by 12, and outlets 3, which connects with
condenser chamber 6: upon shaft A, is also placed a driving pulley as designated
by P, and a multiple pulley O. Placed over disk H, I, and K, and in close proximity
thereto are twelve rotary brushes, the brushes E, are twelve in number, and are covered
with wire bristles one and a half inches in length, the brushes F, are also twelve in
number and are covered with wire bristles one and a quarter inches in length, the
brushes G, are twelve in number, and are covered with bristles one inch in length.

page_text: These brushes are in four sets of three brushes each as seen in plan Fig 2, each set
of brushes have their axis placed parallel to the plane of, and tangential to
disks H, I and K, as shown in drawing, the inner end of the shafts of all the
brushes, revolve in a bearing in the cross frame Z, while their outer ends go through
suitable openings in casing 10, and revolve in journal boxes 9 Each set of these
brushes is revolved by one belt X, driven from pulley N, from which it passes over
idler pulley S, over pulley T, fastened to shaft Y of brush E, from thence to another
idler pulley T¹, revolving on bearing 13 over to another pulley T of another
brush E, and so on in such a manner that each set of brushes of E, F, and G is
driven in the same direction, as every other set, and in a direction opposite to the
rotation of the disks H, I and K The circular casing 10 has fastened to same the
four journal boxes of each set of brushes, frames Z, and covers V, its inner
circumferential surface is constructed at a certain angle with reference to the plane
of disks H, I and K, the object of this, is to compel the seeds as they are thrown off
centrifugally from the disks to rebound at an angle thereto, and fall to the bottom
of casing W, while the covers V are made in two circular halves to allow of removing
them in order to inspect or clean the machine.
The
The casing Lis circular, and surround, and encloses the fan, or exhaust M.
The casing L is fastened to the inner, and bottom inclined sides of the outer,
and surrounding casing W, by means of several projecting lugs 14.
top of casing L has a central opening through which is drawn the lint by the fan
or exhaust M, at its side are discharge outlets 1, 2, and 3, fastened to, and going
through casing W, into condenser chambers, 4, 5 and 6, thus carrying off each grade
of lint from the disks
The distance of disks from brushes may be regulated by the set screw Q, attached
to the bottom bearing of shaft A. The condensers 15 are placed in position as
shown in Figure 1, with outlets 7 for carrying off the different grades of lint, and
outlets 8 for removing dust. The condenser roller 15 is of perforated metal or wire
gauze and above it is a presser roller 16.
In practice I place the cotton seed in hopper B where they are carried upon and
forced downward by the arms of hopper N, on to the disk H, and the feed is regulated
by projecting lugs or arms 11 thus preventing choking, as disk H rotates, the seeds
are carried under brushes E, the teeth on disk H retain them sufficiently to enable
the brushes E to delint them until finally they are thrown centrifugally away from
disk H, against the inner inclined side of casing 10, from which they rebound at an
angle, to casing W, down whose sides they roll, and fall into hopper C: in the mean-
while the fan, or exhaust M draws air through openings in cover V around hopper B,
this air carries off the lint which has been removed from the seed by the action of
disk H, and brushes E, and the lint is-drawn through the exhaust or fan, and forced
through the discharge outlet 1 into the condenser in chamber 4, while the seeds by
their own gravity are carried into hopper C, where they are forced downward upon
disk I, and carried under brushes F, and delinted in a similar manner as when on
disk H, while the lint is carried off by the fan, or exhaust through the discharge
outlet 2, into the condenser in chamber 5, while the seeds now having hint almost
entirely removed are carried into hopper D, thence upon disk K, where they come
in contact with bristle brushes G, and all lint is removed, and the seeds are thoroughly
polished, and carried off through outlet U, in a marketable condition while all lint,
or residue is carried off by the fan through openings 3, to condenser in chamber 6.
The current of air created by the fans M, forces the int and the dust and residue
against the perforated or pervious surface of the condenser rollers 15. The pervious
rollers offer but little resistance to the passage of the air current and the lint being
held against the rollers as they revolve in the direction of the arrows is carried round
beneath roller 16 whereby the lint is compressed into a lap and delivered through
the shute 7, while the dust and residue fall to the bottom of the compartment
and are thrown out through the shute 8. The lint is graded by the successive
rollers 15.

page_text: A striking advantage of my delinter is that all friction or heat is avoided, as my
disks rotate in one direction, while my brushes rotate in an opposite one, the speed of
the brushes being fully one third faster, and the action of the fan produces a free
circulation of air.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
1. In a self feeding delinter such as described, the shaft A, resting on adjustable
bearings for raising or lowering shaft, the hopper B, with propeller or conveyor N,
