of said Invention for "AN IMPROVED PROCESS OF TREATING COTTON SEED TO
SEPARATE THE ADHERING FIBRE AFTER GINNING" to be as follows:-
It
The Invention relates to the treatment of cotton fibre adhering to the seeds
as they come from the gin. The object of the Invention is to separate the fibre as
perfectly as possible from the bulls, and to secure it in any good condition fitted
for the manufacture of paper or for any other uses to which such fibre may be
appropriated. In the treatment of cotton seed, ordinarily, the seeds are cracked
and the kernel removed from the hull. These kernels are pressed separately for
purposes well known.
The hulls heretofore, with their adhering fibre have been
thrown aside as waste material, and at best have been utilized only as fuel.
has been suggested to heat the seed in order to shrink the hull from the kernel and
then crack it, and after it has been cracked to sift out the kernel, and then, by a
separate process to re-grind the residue and subsequently remove the pulverized
hull from the fibre. The disadvantage of this process is that in the grinding or
crushing of the hull and kernel together, the fibre and hull becomes to some extent
saturated or smeared with the oily substance of the kernel which interferes with
the perfect separation of the fibre from the pulverized hull and also renders the fibre
rancid. Further when the kernel is heated in the hull, any suitable amount of
heat will start the oil from the kernel.
This Invention consists in taking the hulls with their adhering fibre, separate
from the kernel, and in subjecting the same to heat sufficient to dry the hulls and
render it brittle without injuring the fibre and then crushing and grinding so as to
pulverize the hull and loosen the fibre, and finally in sifting the residue, so as to
separate the pulverized hull from the fibre. In carrying out the Invention the
hull is separated from the kernel by cracking it and removing the kernel in the
ordinary manner, or the separate hulls with their adhering fibre may be taken as
they come from an ordinary mill. These hulls are subjected to heat, applied

page_text: preferably by passing through the mass, a current of heated air, taking care that
the heat be not sufficient to injure the fibre. A greater degree of heat may be
used upon the separate hulls with safety and thus the hulls may be rendered more
brittle, and more easily separated from the fibre than can be done when the heat is
applied to the seed with the kernel within. These hulls are then ground or
crushed by any suitable or well known mill. The hulls having been removed from
the kernel when this is dried by heating and grinding, are entirely free from any
oily substance and may be pulverized and separated readily from the fibre. There
is no trace of oil or oily substance from the kernels to cause the pulverized hull to
adhere to the fibre, or to soil the fibre itself. The heated air acts readily upon the
dry hull and after the grinding process it is more readily reduced and easily
separated from the fibre. The hulls may be used as a fertilizer or to mix with the
kernel after the oil has been expressed, and the fibre is used for paper and for any
other purpose for which it is required in the arts.

page_text: I, PHILIP MIDDLETON JUSTICE of 55 and 56 Chancery Lane in the County of
Middlesex Fellow of the Institute of Patent Agents do hereby declare the nature
of said Invention for "AN IMPROVED PROCESS OF TREATING COTTON SEED TO
SEPARATE THE ADHERING FIBRE AFTER GINNING" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
The Invention relates to the treatment of cotton fibre adhering to the seeds as
they come from the gin.
The object of the Invention is to separate the fibre as perfectly as possible from
the hulls and to secure it in any good condition fitted for the manufacture of paper
or for any other uses to which such fibre may be appropriated. In the treatment
of cotton seed ordinarily the seeds are cracked and the kernel removed from the
hull.
These kernels are pressed separately for purposes well known. The hulls
heretofore, with their adhering fibre have been thrown aside as waste material and
at best have been utilized only as fuel. It has been suggested to beat the seed in
order to shrink the hull from the kernel and then crack it, and after it has been
cracked, to sift out the kernel, and then, by a separate process to regrind the
residue and subsequently remove the pulverized hull from the fibre. The
disadvantage of this process is, that in the grinding or crushing of the hull and
kernel together the fibre and hull become to some extent saturated or smeared
with the oily substance of the kernel which interferes with the perfect separation
of the fibre from the pulverized hull, and also renders the fibre rancid. Further
when the kernel is heated in the hull any suitable amount of heat will start the
oil from the kernel.
This Invention consists in taking the hulls with their adhering fibre, separate
from the kernel and in subjecting the same to heat sufficient to dry the hulls and
render it brittle, without injuring the fibre and then crushing and grinding so as
to pulverize the hull and loosen the fibre, and finally in sifting the residue so as to
separate the pulverized hull from the fibre.
In carrying out the Invention the hull is separated from the kernel by cracking
it and removing the kernel in the ordinary manner or the separate hulls with their
adhering fibre inay be taken as they come from an ordinary mill.
The hulls are
subjected to heat, applied preferably by passing through the mass a current of
heated air taking care that the heat be not sufficient to injure the fibre. A greater
degree of heat may be used upon the separate hulls with safety and thus the hulls
may be rendered more brittle, and more easily separated from the fibre than can be
done when the heat is applied to the seed with the kernel within. These hulls are
then ground or crushed by any suitable or well known mill. The bulls having
been removed from the kernel when this is dried by heating and grinding are
entirely free from any oily substance and may be pulverized and separated readily
from the fibre. There is no trace of oil or oily substance from the kernels to cause
the pulverized bull to adhere to the fibre, or to soil the fibre itself. The beated air
acts readily upon the dry hull and after the grinding process it is more readily
reduced and easily separated from the fibre. The hulls may be used as a fertilizer
or to mix with the kernel after the oil has been expressed, and the fibre is used for
paper and for any other purpose for which it is required in the arts.

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is:
The hereinbefore described process of removing the fibre of the hulls of cotton
seed by first heating said hulls after the kernel has been removed from them; then
crushing or grinding the hulls, and finally separating the fibre from the pulverized
hulls substantially as described.
