Year: 1873

page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine,
Lako, & Co., Patent Agents, Southampton Buildings, London,
for the Invention of "AN IMPROVED PROCESS FOR THE MANUFACTURE OF
ARTIFICIAL BUTTER, LARD, OR SHORTENING, FOR CULINARY AND OTHER
PURPOSES."-A. communication from abroad by L. D. Roudebush, of
the City and State of New York United States of America.
Sealed the 9th April 1874, and dated the 22nd December 1873.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 22nd December 1873.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "AN IMPROVED PROCESS FOR THE MANU-
FACTURE OF ARTIFICIAL BUTTER, LARD, OR SHORTENING, FOR CULINARY AND OTHER
PURPOSES," a communication, to be as follows :—
The said Invention relates to an improved process of manufacturing a
substance to be used as a substitute for ordinary butter and other like

page_text: •
substances for culinary and other purposes, and is carried into practise as
follows-Fresh animal fat, preferably beef suet, is first reduced to a
fine state in a sausage cutter or by other suitable means; then it is melted
in a steam or water jacketed boiler or tank in such a manner as to
prevent the membrane being scorched, and thus avoiding the taste and
odour of tallow. As soon as the mass is sufficiently melted to allow of
the easy extraction of the scrap therefrom, it should be strained or pressed
through a cloth, thus removing as far as possible all of the membrane.
The clear grease thus obtained is then placed in a clear tank, and
subjected to a high degree of steam or water heat, when any remaining
impurities will arise to the top or adhere to the sides and bottom of the
tank or vessel. The scum should be carefully skimmed off, and then the
pure grease can be drawn off by a properly constructed tap and stop-
cock, so placed in the bottom of the said tank as to avoid disturbing the
sediment adhering to the sides or inside lining of the tank. I thus
obtain a pure, tasteless, and odourless grease or tallow, which can be
treated in either of the following ways, namely,-
First. By combining with the tallow or grease a quantity of refined
cotton seed or other suitable oil, according to the degree of solidity of
the article desired. This mixture should be melted at a moderate heat,
then churned with fresh or sour milk or cream, and then treated according
to the ordinary manner of making butter.
Second. The pure grease or tallow obtained as above described should
when cold be placed in suitable bags and subjected to a heavy pressure
to separate the oil from the stearine, which oil should be churned and
treated as in the first process above described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 22nd June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM 3
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.

and no others, from time to time and at all times thercafter during
the term therein expressed, should and lawfully might make, use,
exercisc, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for
"AN IMPROVED PROCESS FOR THE MANUFACTURE OF ARTIFICIAL BUTTER, LARD, OR
SHORTENING, FOR CULINARY AND OTHER PURPOSES," a communication to me
from abroad by L. D. Roudcbush, of the City and State of New
York, United States of America, upon the condition (amongst others)
that I, the said William Robert. Lake, my executors or admini-
strators, 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 Robert Lake, 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 :-
The said Invention relates to an improved process of manufacturing a
substance to be used as a substitute for ordinary butter and other like
substances for culinary and other purposes, and is carried into practice
as follows:-Fresh animal fat, preferably beef suet, is first reduced to a
fine state in a sausage cutter or by other suitable means; then it is
melted in a steam or water jacketed boiler or tank in such a manner as
to prevent the membrane being scorched, and thus avoiding the taste
and odour of tallow. As soon as the mass is sufficiently melted to
allow of the easy extraction of the scrap therefrom it should be strained
or pressed through a cloth, thus removing as far as possible all of the
membrane. The clear grease thus obtained is then placed in a clean
tank, and subjected to a high degree of steam or water heat, when any
remaining impurities will arise to the top or adhere to the sides and

page_text: bottom of the tank or vessel. The scum should be carefully skimmed
off, and then the pure grease can be drawn off by a properly constructed
tap and stop-cock so placed in the bottom of tho said tank as to avoid
disturbing the sediment adhering to the sides or inside lining of the
tank. I thus obtain a purc, tasteless, and odourless grease or tallow,
which can be treated in either of the following ways, namely,—
First. By combining with the tallow or grease a quantity of refined
cotton seed oil or other suitable oil, according to the degree of solidity
of the article desired. This mixture should be melted at a moderate
heat, then churned with fresh or sour milk or cream, and then treated
according to the ordinary manner of making butter.
Second. The pure grease or tallow obtained as above described should
when cold be placed in suitable bags and subjected to a heavy pressure
to separate the oil from the stearine, which oil should be churned and
treated as in the first process above described.
Having thus fully described the said Invention as communicated
to me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim, the manufacture of artificial
butter, lard, or shortening, for culinary or other uses by the above
described processes, or any part thereof, whereby the same results may
be obtained.
In witness whereof, I, the said William Robert Lake, have here-
unto ant
my hand and goal this Toontz cocond day of Tune in
Witness,
