PROVISIONAL SPECIFICATION.
Improvements in Machines for Removing Lint from Cotton Seed.
I, EDWARD JAMISON O'BRIEN, of Texarkana, in the County of Bowie, and State
of Texas United States of America, Engineer, do hereby declare the nature of this
invention to be as follows:-
This Invention relates to machines for removing lint from cotton seed.
The apparatus comprises two or more vertical cylindrical cotton seed receiving
chambers placed at equal distances apart around a central vertical shaft that carries a
series of circular saws, the forward defining edges of the saw teeth being on radial
lines. The cylinders are open at the side next the saws which project thereinto, the
edges of the openings abutting against combs between the teeth of which the saws
work. The cylinders are traversed by shafts which carry beater blades or arms and
are driven from the saw shaft. The bottoms of the cylinders communicate by
apertures with a trough directly beneath, and in the trough runs an endless belt upon
pulleys that are carried by the beater shafts, and this belt carries buckets by which
the seed in the trough is conveyed to a delivery spout. The cylinders are open at top
and the cotton seed is placed within them. Between the cylinders are arranged lint
chambers which are enclosed except at the inner sides towards the saws. As the saws
rotate, they gather the lint from the seed which lint may be removed by passing
currents of air through the lint chambers which are formed between the cylinders,
any proper arrangement of fans being employed for this purpose. As the seed is
cleaned it passes out into the trough to be carried to the delivery spout by the endless
belt of buckets.
Although I prefer to employ blasts in the chambers, I have found that very
satisfactory work may be done without the blasts owing to the fact that the lint will
be carried from the saws by the centrifugal force generated by the revolution of the
saws. By mounting the saw-carrying shaft as above described, I provide for an equal
distribution of the work, and 1 am enabled to clean a much greater quantity of
cotton seed with a very slight increase of power over that necessary to run the old
form of machine.

Improvements in Machines for Removing Lint from Cotton Seed.
I, EDWARD JAMISON O'BRIEN, of Texarkana, in the County of Bowie, and State of
Texas, United States of America, Engineer, 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 :-
This Invention relates to machines for removing lint from cotton seed; and consists
essentially of certain constructions, arrangements and combinations of elements to be
hereinafter fully described and specifically pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification in which figure 1 is a side view of my improved cotton seed linter, parts
being broken away. Figure 2 is a sectional plan view, on line of figure 1.
Figure 3 is a sectional plan view on line y y of figure 1. Figure 4 is a plan view of
the top plate; and figure 5 is a detail view of a portion of one of the saws.
figures and letters of reference indicate corresponding parts in all the views.

In constructing the linter forming the subject matter of this application, I provide
a base plate 10 above which there is secured an intermediate plate 11 the plate 11
being supported by posts 12. The plate 11 supports a series of outer posts 13 and
between each pair of these posts there is secured a panel 14. Within the line of the
posts 13 I arrange other posts 15 which support the inner edges of sheet iron
cylinders 16, said cylinders being also supported by the posts 13. In the centre of
the apparatus I mount a shaft 20 which carries a series of saws 21 that are mounted
to revolve in the direction of the arrow shewn in figure 3, the forward defining edges
of the saw teeth being on radial lines. As before stated, the edges of the sheet metal
cylinders 16 extend to the posts 15 and these edges abut against combs 19 between
the teeth of which the saws 21 extend. The shaft 20 carries a pulley 22 and a
gear wheel 23 which said gear wheel 23 engages gear wheels 24 that are carried by
shafts 25 which extend upward through the cylinders 16 and these shafts 25 carry
beater blades or arms 26. The plate 11 is formed with apertures
as shewn, and
these apertures are directly above a trough 30 that is arranged below the plate 11.
In connection with the trough 30 I provide a belt 31 that is mounted upon pulleys 32
that are carried by the shafts 25 and this belt 31 carries buckets 33, as shewn. The
trough 30 has an aperture 34 which leads to a delivery spout 35 (see figure 2). In
figure 4 I shew the top plate of the machine which plate serves to support the upper
ends of the shafts 20 and 25, the shafts 25 being supported by bridges 40 the
arrangement being such that openings d are left above the cylinders 16.
In operation, the cotton seed is placed within the cylinders, being introduced
through the openings d. Motion is then imparted to the shaft 20 so that the saws
will be carried forward in the direction of the arrow shewn in figure 3 and as the
saws so move they will gather the lint from the seed which lint may be removed by
passing currents of air through the lint chambers which are formed between the
cylinders 16, said lint chambers being shewn at A, any proper arrangement of fans
being employed for this purpose. As the seed is cleaned it passes outward through
the apertures a into the trough 30 to be carried forward within said trough to the
spout 35 by the buckets of the belt 31.
Although I prefer to employ blasts in the chambers A still I have found that very
satisfactory work may be done without the blasts owing to the fact that the lint will
be carried from the saws by the centrifugal force generated by the revolution of sucb
saws..
By mounting the saw-carrying shaft as above described I provide for an equal
distribution of the work and I am enabled to clean a much greater quantity of cotton
seed with a very slight increase of power over that necessary to run the old form of
machine.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;
1. The combination, with two or more vertical cotton seed receiving chambers, of
a vertical shaft and saws carried thereby, the saws being arranged to project into the
cotton seed receiving chambers, substantially as described.
2. The combination, with two or more cotton seed receiving chambers, of a vertical
shaft, saws carried thereby, agitator shafts arranged within the cotton seed receiving
chambers, and a means for driving the shafts, substantially as described.
3. In a cotton seed linter, the combination, with a structure including lint
chambers A and chambers arranged to receive cotton seed, of a central saw-carrying
shaft, saws carried by the shaft and arranged to enter the cotton seed receiving
chambers, a trough arranged beneath the cotton seed receiving chambers, an endless
belt provided with buckets which enter said trough, and a means for driving the
belt as and for the purpose stated.
4. In a cotton seed linter, the combination, with a structure containing chambers A
and other chambers adapted to receive cotton seed, of shafts mounted within the
cotton seed receiving chambers, blades or arms carried by said shafts, a central shaft,

communication being established between the trough and the chambers, an endless
carrier belt, buckets carried by said belt and arranged to enter the trough, a delivery
spout, and a driving mechanism, substantially as described.
