LETTERS PATENT to William Henry Delamare, of Deptford, in the
County of Kent, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR TREATING COTTON SEEDS."
Sealed the 14th October 1870, and dated the 18th April 1870.
PROVISIONAL SPECIFICATION left by the said William Henry
Delamare at the Office of the Commissioners of Patents, with his
Petition, on the 18th April 1870.
I, WILLIAM HENRY DELAMARE, of Deptford, in the County of
Kent, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN MACHINERY FOR TREATING COTTON SEEDS," to be as follows:-
My Invention has for object to separate the cotton fibre from the
seeds, so as to enable me to utilize the fibre and so as to render the seeds
more fit for crushing.
My machinery consists of a drum mounted horizontally within a
cylindrical casing and provided with any convenient contrivances for
imparting rotary motion thereto. The exterior of the drum and the
interior of the casing are both fitted with punched iron or steel plates,

page_text: so as to furnish a roughened surface for acting on the seeds. At cach
end of the drum I fix a flat ring similar to a washer, and roughened at
that side which faces the drum. I also fix similar rings roughened on
both faces either on the drum or on the inside of the casing, at con-
venient distances apart, so as to divide the annular space between the
drum and casing into several annular chambers. I supply a suitable
quantity of seeds to these chambers at the upper part thereof by any
convenient mechanical means, and after closing the apertures by which
the seeds are introduced rotary motion is imparted to the drum. The
seeds being thus submitted to the action of the rough surfaces of the
drum, casing, and rings the fibre becomes separated therefrom. When
the seeds are cleaned from the fibre I open an outlet extending along
the bottom of the casing, so as to allow the seeds and fibre to fall
through, and a fan or blower acts upon them as they fall, so as to
blow the fibre away from the cleaned seeds. A fresh portion of seeds
may then be supplied to the compartments to be acted upon as before
described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Henry Delamare in the Great Seal
Patent Office on the 18th October 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY DELAMARE, of Deptford, in the County of Kent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of April, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said William Henry Delamare, Her special licence
that I, the said William Henry Delamare, my executors, administrators,
and assigns, or such others as I, the said William Henry Delamare, my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN MACHINERY FOR TREATING COTTON SEEDS," upon the con-

page_text: dition (amongst others) that I, the said William Henry Delamare, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Henry Delamare, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to
the accompanying Drawings, that is to say :—
My Invention has for object to separate the cotton fibre from the seeds,
so as to enable me to utilize the fibre and so as to render the seeds more
fit for crushing.
My machinery consists of a drum mounted horizontally within a
cylindrical casing and provided with any convenient contrivances for
imparting rotary motion thereto. The exterior of the drum and the
interior of the casing are both fitted with punched iron or steel plates,
so as to furnish a roughened surface for acting on the seeds. At each
end of the drum I fix a flat ring similar to a washer and roughened at
that side which faces the drum. I also fix similar rings roughened on
both faces either on the drum or on the inside of the casing, at con-
venient distances apart, so as to divide the annular space between the
drum and casing into several annular chambers. I supply a suitable
quantity of seeds to each of these chambers, at the upper part thereof, by
any convenient mechanical means, and rotary motion is then imparted.
to the drum. The seeds being thus submitted to the action of the rough
surfaces of the drum, casing, and rings, the fibre becomes separated
therefrom. When the seeds are cleaned from the fibre I open an
outlet extending along the bottom of the casing, so as to allow the
seeds and fibre to fall through, and a fan or blower acts upon them as
they fall, so as to blow the fibre away from the cleaned seeds. A fresh
portion of seeds may then be supplied to the compartments to be acted
upon as before described.
Figure 1 of the accompanying Drawings is a side elevation partly in
section, and Figure 2 a transverse section of a machine constructed

page_text: A, A, is a suitable frame or stand provided with bearings B, B, for
a horizontal shaft C, which carries fast and loose driving pulleys D and
a fly wheel E. On this shaft C is mounted a drum F, the exterior of
which has a roughened surface formed by preference of punched iron or
steel plates; G is a cylindrical casing secured to the frame A, so as to be
concentric with the drum F which is placed within it. The interior of
this casing has a roughened surface similar to the
drum F.
exterior of the
As shown in the Drawings the casing is composed of outer hoops or
ribs g, to which plates of punched iron or steel are fixed. At each end
of the drum F is fixed a flat ring H (one of which is seen in Figure 1),
roughened on that side which faces the opposite end of the drum.
Similar rings I, I, roughened on both sides, are fixed at convenient
distances apart, so as to divide the annular space between the drum and
the casing into several annular chambers or compartments J, J. Or
instead of these rings being fitted to the outside of the drum they
may be fixed to the inside of the casing G. The casing G has an
outlet or opening extending along the bottom thereof and provided with
a door K.
The mode which I prefer for supplying the seed to be cleaned to the
compartments J, J, is that shown in the Drawings. It consists of a
box L and slide M; the box L is open at the bottom and fits upon the
top of the casing G, which has a longitudinal opening corresponding
with the opening of the box. The slide M consists of two shelves N, O,
each of which has an opening, the opening in the upper shelf being
in the front portion and the opening in the lower shelf being in
the back portion. The slide is connected with the door K at the
bottom of the casing by levers P, one at each end of the machine, in such
manner that when the door is closed the slide is drawn out and when
the door is open the slide is pushed in.
from the upper part of the box L falls
shelf N upon the front portion of the lower shelf O; and when the slide
is drawn out the seed falls from the lower shelf O through the opening
of the same into the chambers J, J, while the back portion of the upper
shelf prevents more seed descending from the upper part of the box L.
The levers P which work the slide L and the door K may either be
actuated by hand at the discretion of an attendant or automatically, at
suitable intervals, by ordinary mechanical contrivances in connection
When the slide is pushed in seed
through the opening of the upper

page_text: with the machine.
The seeds which enter the chambers J, J, are, owing
to the rotary motion imparted to the drum F, submitted to the action
of the rough surfaces of the drum F, casing G, and rings H and I, so
that the fibre becomes separated therefrom. When the seeds and fibre
in a separated state fall together from the several chambers J, through
the opening at the bottom of the casing, the fibre may be blown away
from the seeds as they fall by a fan or blower of any ordinary and
suitable construction worked by a strap from the pulley Q or otherwise.
I do not claim as my improvements in machinery for treating
cotton seeds the employment generally of a rotating drum and an
outer casing having between them a space to which the seeds are
supplied, nor do I claim the employment of rough surfaces for acting
upon the seeds. But what I do claim is, constructing machinery for
treating cotton seeds, of a drum and casing provided with rough surfaces
and having between them a space which is divided into separate
chambers or compartments, and each of which chambers or compartments
is supplied with, cleans, and discharges a separate or distinct portion
of the seeds under treatment, substantially as herein-before described.
In witness whereof, I, the said William Henry Delamare, have.
hereunto set my hand and seal, this Eighteenth day of October,
One thousand eight hundred and seventy.
