I, JAMES EDWARD DUYCK, of West Farleigh, in the County Kent, Gentle-
man, do hereby declare the nature of the said Invention for "AN IMPROVE-
MENT IN TREATING COTTON SEED IN ORDER TO EXTRACT COLOR FROM THE OIL
OBTAINED THEREFROM," to be as follows:-
My Invention consists in treating cotton seed with an alkali, either prior to
or while being crushed in order, to obtain the oil therefrom, which treatment
extracts the color from the oil, or fixes the color in the other products resulting
from the pressure.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
EDWARD DUYCK, of West Farleigh, in the County of Kent, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of March, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
James Edward Duyck, Her special licence that I, the said James Edward
Duyck, my executors, administrators, and assigns, or such others as I, the
said James Edward Duyck, 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 "AN
IMPROVEMENT IN TREATING COTTON SEED IN ORDER TO EXTRACT COLOR FROM THE
OIL OBTAINED THEREFROM" upon the condition (amongst others) that I, the said
James Edward Duyck, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Edward Duyck, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
My Invention consists in treating cotton seed with an alkali, either prior to
or while being crushed in order to obtain the oil therefrom, which treatment
extracts the color from the oil, or fixes the color in the other products resulting
from the pressure. The manner in which my Invention is carried into effect
is as follows:-
When I operate on Egyptian or other cotton seeds with the husk on, or with
the husk and lint, I sprinkle them over with from about ten to twenty per
cent. of their weight, according to the cleanness of the seed, with an alkali,
and I prefer to use a caustic alkali, say, caustic soda, or potash lees, of the
°

page_text: strength of about 20 to 30 Beaumé. The seed is then well turned over to
insure its being uniformly damped or wetted, and after having been allowed to
soak, I either pass it through rollers or under stones in the usual manner to
prepare it for pressing.
I operate upon the kernals of cotton seed before being crushed in a manner
similar to that just described, but I use a smaller quantity of caustic lee, as I
find about five per cent. thereof sufficient to discolor the oil contained in them.
Cotton seeds after being crushed, and whether they have been prepared
before being crushed or not, may have the alkali applied during the crush-
ing or working thereof by passing them through rollers kept constantly wet
by feeding the caustic lee on flannel or other suitable material; or the alkali
maybe sprinkled or thrown over the seeds and under the stones while
grinding.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I do not restrict myself
to the employment of any particular alkali, caustic or otherwise; but I claim
the treating of cotton seeds with an alkali, either before or during the process
of crushing, previous to the oil being extracted therefrom, in order to obtain
discolored oil.
In witness whereof, I, the said James Edward Duyck, have hereunto set
my hand and seal, this Eighth day of September, One thousand eight
hundred and fifty-seven.
