Year: 1871

page_text: LETTERS PATENT to Anjel Vazquez and Just Edmund Rosenberg,
both of Santiago, Chili, but at present of 172, Fleet Street, in the
City of London, for the Invention of "A NEW OR IMPROVED MODE OF
PRESERVING MEAT POULTRY, ĜAME. and Fish.”
PRESERVING MEAT, POULTRY, GAME,
AND FISH"
PROVISIONAL SPECIFICATION left by the said Anjel Vazquez and
Just Edmund Rosenberg at the Office of the Commissioners of
Patents, with their Petition, on the 14th December 1871.
We, ANJEL VAZQUEZ and JUST EDMUND ROSENBERG, both of
Santiago, Chili, but at present of 172, Fleet Street, in the City of
London, do hereby declare the nature of the said Invention for "A NEW
OR IMPROVED MODE OF PRESERVING MEAT, POULTRY, GAME, AND FISH," to be as
follows:-
The object of our Invention is to preserve meat, poultry, game, and
fish in the fresh or uncooked state. We proceed as follows:—
We take a cask containing clear water and place therein acetate of
lime (CaO, C'H'O³), generally called brown acetate of lime, until

page_text: the liquid marks 6° in the areometer (salt weight). We then add a
small quantity of pure acetic acid (C'HPO³, HO), of 8° in the
areometer (acid weight), so that the liquid will produce a sensible acid
reaction upon blue reaction paper. The liquid being thus prepared and
filtered, if necessary, is ready for use in the preservation of the meat.
The casks to be employed should be a little more than half filled with
the liquid, and be then filled up with the meat.
It is advantageous to place the meat in the neutral liquid first, that is
to say, in the solution of acetate of lime, and to leave it there for two or
three days, the position of the casks being altered each day, then the
acetic acid is added and the casks filled up with the neutral solution of
acetate of lime.
If preferred the liquid may be injected into the animal before it is
divided into joints, but the immersion will generally be found sufficient.
The casks being closed the meat thus treated will remain quite fresh for
a long time. When taken out for cooking it should be washed first
with cold water, then with warm water, and afterwards with salt water
if necessary.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Anjel Vazquez and Just Edmund Rosenberg in the 2
Great Seal Patent Office on the 11th June 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ANJEL
VAZQUEZ and JUST EDMUND ROSENBERG, both of Santiago, Chili, but at
present of 172, Fleet Street, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 2
Letters Patent, bearing date the Fourteenth day of December, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Anjel Vazquez and Just Edmund Rosenberg
Her special licence that we, the said Anjel Vazquez and Just Edmund 3
Rosenberg, our executors, administrators, and assigns, or such others as
we, the said Anjel Vazquez and Just Edmund Rosenberg, our executors,
administrators, and assigns, should at any time agree with, and no others,

page_text: 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 "A NEW OR IMPROVED MODE
OF PRESERVING MEAT, POULTRY, GAME, AND FISH," upon the condition
(amongst others) that we, the said Anjel Vazquez and Just Edmund
Rosenberg, our executors or administrators, by an instrument in
writing under our, or their, or one of our 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 we, the said Anjel Vazquez and Just Edmund
Rosenberg, do hereby declare the nature of our 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 :-
The object of our Invention is to preserve meat, poultry, game, and
fish in the fresh or uncooked state. We proceed as follows:-
We take a cask containing clear water, and place therein acetate of
lime (CaO, C'H³O'), generally called brown acetate of lime, until
the liquid marks 6° in the areometer (salt weight). We then add a
small quantity of pure acetic acid (C*H³O³, HO), of 8° in the
areometer (acid weight) so that the liquid will produce a sensible acid
reaction upon blue reaction paper. The liquid being thus prepared and
filtered, if necessary, is ready for use in the preservation of the meat.
The casks to be employed should be a little more than half filled with
the liquid, and be then filled up with the meat.
It is advantageous to place the meat in the neutral liquid first, that is
to say, in the solution of acetate of lime, and to leave it there for two or
three days, the position of the casks being altered each day; then the
acetic acid is added and the casks filled up with the neutral solution of
acetate of lime.

it is divided into joints, but the immersion will generally be found
sufficient.

with cold water, then with warm water, and afterwards with salt water
if necessary.
We claim as our Invention the mode herein-before 'described of
preserving meat, poultry, game, and fish, in the fresh or uncooked
state.
In witness whereof, we, the said Anjel Vazquez and Just Edmund
Rosenberg, have hereunto set our hands and seals, this First day
of June One thousand eight hundred and seventy-two.
