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 FOR
SEPARATING THE FIBRE AND OBTAINING OIL AND FOOD PRODUCTS THEREFROM
to be as follows:-
:-
"
This Invention relates to an improved method of treating cotton seed for the
purpose of obtaining its products at less expense and in better condition.
Heretofore as is well known, cotton seed has been crushed with the hull and
kernel together and the oil expressed. This process requires that the hull, which
contains no oil whatever, shall be subjected to the same amount of compression as
the kernel itself which alone contains the oil.
The food product which has the mixed hull and kernel is in good condition for
its purpose but the oil is rendered darker by reason of the presence of the hull in
the compressed mixture. It has also been common to hull the American upland
seed and crush only the kernel, and to burn the hull with the adherent lint,
as fuel.
This avoids the discolouration of the oil caused by pressing the hull; but the
food product that is to say the pure kernel is lacking in an element required to
make it a proper food for cattle to be fed by itself that is to say-it lacks the
hull, which when ground with the kernel, makes a better and more wholesome
food.
The Invention therefore consists in the method of treating cotton seed by taking
the hull separated from the kernel and grinding it, in removing the fibre therefrom
and then mixing the ground hull with the crushed and pressed kernel as hereinafter
more particularly described. The hull is ground separately and when it contains
fibre it is separated therefrom in the manner described in the Specification of an
application filed by me of even date. After thus grinding the hull and separating
the fibre therefrom which is unfit for food but is valuable for other purposes, the
ground hull is mixed with the kernel (from which the oil has been pressed) and

in its best form and the oil in its best condition without any of the discoloration
arising from the compression with the hull. The various steps in the operation
may be carried on by well known means; any suitable mill being used for grinding
the hull; any ordinary press for pressing the kernel, and the fibre may be removed
from the ground hull by any suitable winnowing or sifting apparatus.

It has also been common to hull the American upland seed and crush only the

discoloration of the oil caused by pressing the hull, but the food product--that is
to say the pure kernel is lacking in an element required to make it a proper food
for cattle to be fed by itself-that is to say, it lacks the hull, which when ground
with the kernel makes a better and more wholesome food. The Invention there-
fore consists in the method of treating cotton seed by taking the hull separated
from the kernel and grinding it, in removing the fibre therefrom, and then mixing
the ground hull with the crushed and pressed kernel, as hereinafter more particularly
described and claimed.
The hull is ground separately and when it contains fibre it is separated therefrom
in the manner described in the Specification of an application filed by me of even
date. After thus grinding the hull and separating the fibre, therefrom, which is
unfit for food but is valuable for other purposes, the ground hull is mixed with
the kernel (from which the oil has been pressed) and forms thereby the food
product.
The fibre and the food product are thus obtained in their best form, and the oil
in its best condition and without any of the discolouration arising from the
compression with the hull. The various steps in the operation may be carried on
by well known means; any suitable mill being used for grinding the hull; any

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 herein described method of treating cotton seed consisting in taking the hull
separated from the kernel and grinding it, in removing the fibre therefrom, and
then mixing the ground hull with the crushed and pressed kernel all substantially
as described.
