A. S. EASTHAM, OF WHARITON, TEXAS.
COTTON-CLEANER.
Specification of Letters Patent No. 31,661, dated March 12. 1861.Tob all whom it mnay concern:
Be it known that I, A. S. EasTESAI., of
Wharton, in the county of Wharton and
State of Texas, have invented a new and
Improved Machine for Cleaning Cotton Pre-
paratory to Ginning the Same; and I do
hereby declare that the following is a full,
clear, and exact description of the same, ref-
erence being had to the annexed drawing,
making a part of this specification, in which-
Figure 1, is a side sectional view of my
invention, taken in the line ry, y Fig. 3.
Fig. 2, is a transverse vertical section of the
same, taken in the line c .x Fig. 1. Fig. 3, is
a plan or top view of the same.
Similar letters of reference indicate corre-
sponding parts in the several figures.
The invention consists in the employment
or use of a series of revolving brush cylin-
ders, in connection with a card cylinder,
stationary brush and stripping boards, and
wire screens; all being combined and ar-
ranged substantially as hereinafter shown
and described, whereby cotton, preparatory
to ginning, may have dust, dirt, hulls and
all foreign substances separated fiom it.
To enable those skilled in the art to fully
understand and construct my invention, I
will proceed to describe it.
A. represents a framing which may be of
rectangular form, and constructed in such
a way as to sustain an oblong rectangular
box or case B. and the necessary working
parts of the machine. The box or case B. is
open at its bottom, and at one end of it there
is a hopper C. into which the cotton to be
cleaned is fed.
D. is a cylinder which is placed in the box
or case B. and at the bottom of hopper C.
This cylinder is provided with brushes a, at
its periphery, the brushes being placed in
longitudinal rows on the cylinder, the rows
being at equal distances apart.
E. F. are two boards which are placed in
the box or case B. at right angles to each
other, and each board is provided with a
row of brushes b. In an oblique downward
direction from a cylinder D. there is a simi-
lar cylinder G. provided with brushes c. and
also two brush boards H. I. similar to E. F.
and having the same relative position with
each other and their cylinder G. Below the
cylinder G. and on the same plane with cyl-
inders D. G. there is another brush cylinder
J. which is constructed precisely similar to
the brush cylinders D. G.K. K. are inclined boards placed trans-
versely in the box or case B. at such points
as to leave spaces d. immediately below the
cylinders I). G. J. aund card cylinder M. o60
Screen L. is composed of wires e. and cylin-
drical bars f. The latter may be of wood
and of larger diameter than e.
M. is a large brush or card cylinder which
is placed in the box or case B. parallel with 65
the cylinders D. G. J. The cylinder M. is
opposite cylinder J. as shown clearly in Fig.
1, and over the cylinder M. there are placed
two brush cylinders N. N'. which are at op-
posite sides of a vertical plane in which the 70
axis of the cylinder M. is placed.
O'. O. O. are three brush 'cylinders, placed
in the box or case B. The axes of these cyl-
inders are in a horizontal plane, and said
cylinders are larger in diameter than the 75
cylinders D. G. J. but smaller than cylinder
. The cylinders O. are also provided with
wires bx. between their brushes. Under-
neath the cylinders O. there are placed con-
cave screens P. which are constructed pre- 80
cisely the same as the screens L. L'.
Q. Q. Q. are inclined boards which are
placed in the box or case B. and are at the
front side of each cylinder O. These boards
have attached to their lower ends plates g. 85
which extend down nearly to the screens P.
as shown clearly in Fig. 1.
The brush cylinders D. G. J. are solid,
but the larger brush cylinders O'. O. O. are
of skeleton form and provided with radial 90
plates h. attached to the axes i. These plates
serve as fans, and as they rotate generate a
blast within the box or case. A'. is a flue
which communicates with the lower parts of
the box or case B. 95
The operation of the machine is as fol-
lows: Motion is given the several brush-
cylinders, in the direction of the arrows, by
means of belts j. and pulleys and gearing ak.
as shown more particularly in Fig. 3. Gear- 100
ing however may be substituted for belts, if
desired. The cotton to be cleaned is fed into
the hopper C. The cylinder D. carries the
cotton around part of the stationary brushes
7,. b. of the boards E. F. This operation 05
loosens the hulls in the cotton, and a portion
of then will drop through the first space d.
The cotton is passed down by the several
cylinders D. G. J. to the cylinder M. and in
passing down the hulls are loosened in con- 110
sequence of the cotton being drawn up around
the lower edges of the boards F. I. and the
