AN IMPROVED PROCESS FOR OBTAINING GELATINE AND OTHER PRODUCTS FROM ANIMAL SUB- STANCES
Year: 1869

page_text: LETTERS PATENT to William Robert Lake; of the "International
Patent Office," No. 8, Southampton Buildings, Chancery Lane,
London, Consulting Engineer, for the Invention of "AN IMPROVED
PROCESS FOR OBTAINING GELATINE AND OTHER PRODUCTS FROM ANIMAL SUB-
STANCES." A communication from abroad by David Kitchell Tuttle,
Orazio Lugo, William John Hooper, and Theodore Hooper, all of
Baltimore, Maryland, United States of America.
Sealed the 25th September 1869, and dated the 19th May 1869.
PROVISIONAL SPECIFICATION left by the said William Robert Lako
at the Office of the Commissioners of Patents, with his Petition,
on the 19th May 1869.
I, WILLIAM ROBERT LAKE, of the "International Patent Office,"
No. 8, Southampton Buildings, Chancery Lane, London, Consulting
Engineer, do hereby declare the nature of the said Invention for "AN
IMPROVED PROCESS FOR OBTAINING GELATINE AND OTHER PRODUCTS FROM ANIMAI
SUBSTANCES," a cummunication, to be as follows:-
The nature of the said Invention consists in obtaining pure gelatine
or glue stock from such substances as contain glue-forming materials

page_text: by eliminating and saving the oils and fats therein contained, and this
is accomplished by means of benzine, naptha, or other equivalent hydro-
carbons in the manner herein-after described.
The crude animal substances, such as the flesh, fats, skins, tandons,
bones, horns, feet, either with or without a previous treatment with lime,
are treated with benzine or other equivalent hydrocarbon in a proper
vessel provided with a condensing apparatus for saving any vaporized
benzinc, or in a closed vessel at an elevated temperature. After a few
hours' digestion the hydrocarbon solution of the fats and oils is drawn
off, and may be treated by any of the well-known methods for recovering
the volatile hydrocarbon, which may be again used in subsequent
operations, the oils and fats are saved and utilized. The animal matters
or purified glue stock is now ready for conversion into glue by heating
with water in the ordinary way.
Satisfactory results are obtained by the following modifications of the
snid process-The crude glue-making materials after having been
treated with any aqueous solutions for purification, and while in a
hydrated condition, are treated with a sufficient quantity of benzine
or other equivalent hydrocarbon to dissolve the oils and fats. IIcat is
applied by steam or other suitable means, whereby in a few hours a
hydrocarbon solution of the oily and fatty matters and an aqueous
substratum containing the gelatine or glue are obtained. These
solutions are separated by decantation; the former is treated for the
recovery of the hydrocarbon and the utilization of the oils and fats, the
latter is converted into marketable gelatine or glue by the ordinary
process.
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 18th November 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the International Patent O.lice, No. 8, Southampton
Buildings, Chancery Lane, London, Consulting Engineer, send greeting.
WHEREAS Her most. Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of May, in the year

page_text: of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Robert Lake, Her special
licence that I, the said William Robert Lake, my executors, adminis-
trators, and assigns, or such others as I, the said William Robert Lake,
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, excrcise,
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 OBTAINING GELATINE AND OTHER PRODUCTS FROM ANIMAL SUBSTANCES,"
upon the condition (amongst others) that I, the said William Robert
Lake, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and scals, should particularly describo
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 nature of the said Invention consists in obtaining pure gelatine
or glue stock from such substances as contain glue forming materials
by eliminating and saving the oils and fats therein contained, and this
is accomplished by means of benzine, naptha, or other equivalent
hydrocarbons in the manner herein-after described.
The crude animal substances, such as the flesh, fats, skins, tendons,
bones, horns, feet, either with or without a previous treatment with lime,
are treated with benzine or other equivalent hydrocarbon in a proper
vessel, provided with a condensing apparatus for saving any vaporized
benzine, or in a closed vessel at an elevated temperature. After a few
hours' digestion the hydrocarbon solution of the fats and oils is drawn
off, and may be treated by any of the well-known methods for recovering
the volatile hydrocarbon, which may be again used in subsequent
operations. The oils and fats are saved and utilized. The animal matter
or purified glue stock is now ready for conversion into gluc by heating
with water in the ordinary way.

page_text: Satisfactory results are obtained by the following modifications of the
said process-The crude glue making materials after having been
treated with any aqueous solutions for purification, and while in a
hydrated condition, may be treated with a sufficient quantity of benzine
or other equivalent hydrocarbon to disolve the oils and fats. Heat
is applied by steam or other suitable means, whereby in a few hours
a hydrocarbon solution of the oily and fatty matters and an aqueous
substratum containing the gelatine or glue are obtained. These
solutions are separated by decantation; the former is treated for the
recovery of the hydrocarbon and the utilization of the oils and fats,
the latter is converted into marketable gelatine or glue by the ordinary
process.
Having now described the said Invention as communicated to me
by my foreign correspondent, and the manner of carrying the same into
practice, I claim, the process herein described for preparing glue stock
consisting in treating the glue stock material with benzine, naptha, or
other equivalent solvent of the oils and fats, substantially as described.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Eighteenth day of November, in
the year of our Lord One thousand eight hundred and sixty-nine.
WILLIAM ROBERT LAKE. (L.S.)
