Year: 1855

page_text: LETTERS PATENT to Anguish Honour Augustus Durant, of Tong Castle,
Salop, Esquire, for the Invention of "AN IMPROVEMENT IN EXTRACTING
CASTOR OIL."
Sealed the 21st December 1855, and dated the 6th July 1855.
PROVISIONAL SPECIFICATION left by the said Anguish Honour Augustus
Durant at the Office of the Commissioners of Patents, with his Petition,
on the 6th July 1855.
I, ANGUISH HONOUR AUGUSTUS DURANT, of Tong Castle, Salop, Esquire, do
hereby declare the nature of the Invention for "AN IMPROVEMENT IN EXTRACTING
CASTOR OIL" to be as follows:-
My Invention consists of a new and improved method of making and
clarifying oil for various purposes from the castor seeds, by depriving them of
the outer skin or cuticle previous to crushing and heating and sieving them,
thus producing a clearer and finer oil than heretofore, and with a much less
waste of material, and which oil I purpose calling "castrine," the outer cuticle
being then applicable for manure and other purposes.

by the said Anguish Honour Augustus Durant in the Great Seal Patent
Office on the 5th January 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANGUISHI
HONOUR AUGUSTUS DURANT, of Tong Castle, Salop, Esquire, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of July, in the year of our Lord One
thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Anguish Honour Augustus Durant, Her special license that I, the said
Anguish Honour Augustus Durant, my executors, administrators, and assigns,
or such others as I, the said Anguish Honour Augustus Durant, 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 EXTRACTING CASTOR OIL," upon the
condition (amongst others) that I, the said Anguish Honour Augustus Durant,
my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 Anguish Honour Augustus Durant, do
hereby declare the nature of the 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 relates to a new and improved method of making and
clarifying oil for various purposes from the castor seed, by depriving them of
the outer skin or cuticle by means of rollers or stones or other similar
processes previous to crushing, treating, sieving, and heating them, thus
-producing-a-clearer-and-finer-oil-than-heretofore-and-with-a-much-less-waste-
of material, and which oil I purpose calling "castrine," the outer cuticle being
then applicable for manure and other purposes. By my process of making the
oil from the seed, when the cuticle or outer skin is removed, the thicker
portion or sterine, which is now lost (by being mixed and left with the outer

page_text: skin or cuticle), is obtained, and the oleaginous or thin portion of the oil is not
colored and deteriorated, consequently there is not the loss of time, capital,
and material in crushing the seed with the outer skin or cuticle, as heretofore.
The oil thus obtained can be purified by jets of gas, acids, and heat at about
150 to 160 degrees.
In witness whereof, I, the said Anguish Honour Augustus Durant,
have hereunto set my hand and seal, this Second day of January,
in the year of our Lord One thousand eight hundred and fifty-six.
Witness,
ANGUISH HONOUR AUGUSTUS DURANT. (L.S.)
