Year: 1858

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, E. C., Patent Agent, for the Invention of "Im-
PROVEMENTS IN THE PRESERVATION OF ANIMAL AND VEGETABLE SUBSTANCES.".
- A communication from Gabriel Blondin.
Sealed the 16th July 1858, and dated the 20th January 1858.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 20th January 1858.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, E.C., Patent Agent, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE PRESERVATION OF ANIMAL AND VEGETABLE SUB-
STANCES," (a communication from Gabriel Blondin,) to be as follows:-
These improvements consist in coating animal and vegetable substances with
a compound formed of vegetable albumen and a suitable antiseptic material.
The coating is effected by immersing the substances to be preserved in the
prepared compound two or three times, each coat being dried or set in a
current of air before the next is applied. The object of combining an antiseptic
agent with the vegetable albumen is to prevent a partial decomposition of the
substances occurring before the protective coating is properly hardened. The
following means may be adopted for carrying the Invention into effect:-
Supposing a joint of meat to be the substance to be preserved, the meat
(with as little blood in it as possible) is first washed or immersed in water

page_text: impregnated with acetate of alumina and allowed to drain, it is then suspended
by a string and allowed to descend into a bath composed by placing gum
adragantbe or (gum dragon) in heated water for about 24 hours, straining the
solution, then mixing with it a warm solution of gelatine or paste, and finally
adding acetate of alumina, and straining. The meat is kept in this bath for
about 2 minutes, being drawn and moved about in it by the string, it is then
taken out and suspended in a current of dry air for about 24 hours. The
immersion, &c. are, then repeated once or twice, as may be considered desirable,
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent
Office on the 20th July 1858.
. TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, E. C.,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of January, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Richard Archibald Brooman, Her special licence that I, the said
Richard Archibald Brooman, my executors, administrators, and assigns, or
such others as I, the said Richard Archibald Brooman, 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 "IMPROVEMENTS IN THE PRESERVATION OF
ANIMAL AND VEGETABLE SUBSTANCES," (a communication from Gabriel Blondin,
a foreigner residing abroad,) upon the condition (amongst others) that I, the
said Richard Archibald Brooman, my executors or administrators, 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 Richard Archibald Brooman, do hereby
declare the nature of the said Invention, and in what manner the same is

page_text: to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
These improvements consist in coating animal and vegetable substances with
a compound formed of vegetable albumen and a suitable antiseptic material.
The coating is effected by immersing the substances to be preserved in the
prepared compound two or three times, each coating being dried or set in a
current of air before the next is applied. The object of combining an antiseptic
agent with the vegetable albumen is to prevent a partial decomposition of the
substances occurring before the protective coating is properly hardened. The
following means may be adopted for carrying the Invention into effect :-
Supposing a joint of meat to be the substance to be preserved, the meat
(with as much of its blood extracted as possible) is first washed or immersed
in water impregnated with acetate of alumina and allowed to drain, it is then
suspended by a string, and allowed to descend into a bath composed by placing
about one pound of gum adraganthe (or gum dragon) in from one and a half
to two gallons of heated water for about twenty-four hours, straining the
solution, then mixing with it a warm solution of about six ounces of gelatine
or paste, and finally adding about ten ounces of acetate of alumina, mixing
and straining. The meat is kept in this bath for about two minutes, being
drawn and moved about in it by the string, it is then taken out and suspended
in a current of dry air for about twenty-four hours. The process of immersion,
&c. is then repeated once or twice, as may be considered desirable.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim the method of
treating animal and vegetable substances, for the preservation of the same,
by coating them with a compound formed of vegetable albumen and any
suitable antiseptic material; also the method of applying the said compound
as herein-before described.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twentieth day of July, One thousand
eight hundred and fifty-eight.
R. A. BROOMAN. (L.S.)
