Year: 1870

page_text: LETTERS PATENT to William Gostwyck Gard, of Breaston, in the
County of Derby, for the Invention of "AN IMPROVED MIXTURE FOR
PRESERVING MEAT, FISH, POULTRY, GAME, CHEESE, AND OTHER ANIMAL
SUBSTANCES."
Sealed the 23rd May 1871, and dated the 26th November 1870.
PROVISIONAL SPECIFICATION left by the said William Gostwyck
Gard at the Office of the Commissioners of Patents, with his
Petition, on the 26th November 1870.
I, WILLIAM GOSTWYCK GARD, of Breaston, in the County of Derby,
do hereby declare the nature of the said Invention for "AN IMPROVED
MIXTURE FOR PRESERVING MEAT, FISH, POULTRY, GAME, CHEESE, AND OTHER ANIMAL
SUBSTANCES," to be as follows:-
This Invention is designed for preserving animal food generally, but
more particularly butchers' meat from fly-blows in summer, and preserve
it sweet at such seasons, but is equally adapted for preserving meat at
other seasons for many weeks, months, or years.

page_text: The means by which I propose to accomplish this object are as
follows-I form a mixture of sulphate of alumina and potass of
commerce or its equivalents, with chloride of sodium or the ordinary
salt of commerce, or its equivalent, or I form a mixture of sulphate of
alumina of commerce or its equivalent with chloride of sodium or the
ordinary salt of commerce or its equivalent, or a combination of the
before-mentioned sulphate of alumina and potass, or its equivalents, and
sulphate of alumina with common salt in the proportion of about seven
pounds of sulphate of alumina and potass or its equivalents, and one
hundred and twelve pounds of common salt or about the same proportions
of sulphate of alumina and common salt, or I make a mixture (in any
proportions) of sulphate of alumina and potass or its equivalents and
sulphate of alumina with about the same quantity of common salt, the
whole being dissolved in about three hundred and twenty pounds weight
of water, but I prefer a mixture of the above proportions of sulphate
of alumina and potass and common salt, thus forming a strong solution
or brine, and into this mixture or brine I steep the edibles or other
substances to be preserved for a few minutes, hours, or days, according
to the length of time they are intended to be preserved.
Edibles or other substances requiring to be kept for two or three days
need only be immersed for from ten to fifteen minutes, but if such
substances are to be kept for an indefinite time they should remain in
the mixture for from three to eight days (I prefer six days) and then
be either hung up and dried, or kept in a strong brine made with
common salt.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Gostwyck Gard in the Great Seal Patent
Office on the 24th May 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GOSTWYCK GARD, of Breaston, in the County of Derby, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of November, in
the year of our Lord One thousand eight hundred and seventy, in the
thirty-fourth year of Her reign did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Gostwyck Gard,

page_text: Her special licence, that I, the said William Gostwyck Gard, my
executors, administrators, and assigns, or such others as I, the said
William Gostwyck Gard, 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 IMPROVED MIXTURE FOR PRESERVING
MEAT, FISH, POULTRY, GAME, CHEESE, AND OTHER ANIMAL SUBSTANCES," upon
the condition (amongst others) that I, the said William Gostwyck Gard,
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 William Gostwyck Gard, 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, that is to say :-
This Invention is designed for preserving animal food generally, but
more particularly butchers' meat from fly-blows in summer, and preserve
it sweet at such seasons, but is equally adapted for preserving meat at
other seasons for many weeks, months, or years.
The means by which I propose to accomplish this object are as
follows: I form a mixture of sulphate of alumina and potass of
commerce or its equivalents, with chloride of sodium or the ordinary
salt of commerce or its equivalent, or I form a mixture of sulphate of
alumina of commerce or its equivalent with chloride of sodium or the
ordinary salt of commerce or its equivalent, or a combination of the
before-mentioned sulphate of alumina and potass or its equivalents
and sulphate of alumina with common salt, in the proportion of about
seven pounds of sulphate of alumina and potass or its equivalents and
one hundred and twelve pounds of common salt, or about the same
proportions of sulphate of alumina and common salt, or I make a
mixture (in any proportions) of sulphate of alumina and potass or its
equivalents and sulphate of alumina with about the same quantity of
common salt, the whole being dissolved in about three hundred and

page_text: twenty pounds weight of water, but I prefer a mixture of the above
proportions of sulphate of alumina and potass and common salt, thus
forming a strong solution or brine, and into this mixture or brine I steep
the edibles or other substances to be preserved for a few minutes, hours,
or days, according to the length of time they are intended to be
preserved.
Edibles or other substances requiring to be kept for two or three days
need only be immersed for from ten to fifteen minutes, but if such
substances are to be kept for an indefinite time they should remain in
the mixture for from three to eight days (I prefer six days), and then
be either hung up and dried or kept in a strong brine made with common
salt.
Having now fully described and set forth the nature and object of my
said Invention for "An Improved Mixture for Preserving Meat, Fish,
Poultry, Game, Cheese, and other Animal Substances," together with
the best means I am acquainted with for carrying the same into
practical effect, I would remark in conclusion that what I claim as my
Invention intended to be secured to me by the herein-before in part
recited Letters Patent, is as follows:-I claim mixing sulphate of
alumina and potass of commerce or its equivalents with chloride of
sodium or the ordinary salt of commerce or its equivalent to form a
mixture suitable for preserving meat and other edibles, substantially as
above described.
In witness whereof, I, the said William Gostwyck Gard, have
hereunto set my hand and seal, this Twenty-second day of May,
in the roar of our Lord One thousand night
