Year: 1859

page_text: LETTERS PATENT to Edward Joseph Hughes, of the Firm of Hughes &
Son, Patent Agents, 128, Chancery Lane, London, for the Invention of
"IMPROVEMENTS IN PRESERVING ANIMAL FOOD, POULTRY, GAME, FISH, FRUIT,
AND OTHER SIMILAR SUBSTANCES."-A communication by Edouard Gorges,
of Paris.
Sealed the 22nd August 1859, and dated the 1st March 1859.
PROVISIONAL SPECIFICATION left by the said Edward Joseph Hughes,
at the Office of the Commissioners of Patents, with his Petition, on the
1st March 1859.
I, EDWARD JOSEPH HUGHES, of the Firm of Hughes & Son; Patent
Agents, 123, Chancery Lane, London, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN PRESERVING ANIMAL FOOD, POULTRY,
GAME, FISH, FRUIT, AND OTHER SIMILAR SUBSTANCES," as communicated to me
by Edouard Gorges, of Paris, to be as follows:-
To preserve animal food, poultry, and game in their natural state, they
must be inimersed for about one or two hours according to the quantity to be

page_text: operated upon, in a bath of tartaric acid at about five degrees of temperature;
or instead of the tartaric acid, tartrate acid of potassium may be used. The taste
of the acid may be neutralised by a second bath of bicarbonate of sodium;
the phosphate of sodium will be a good substitute for the alkali, the free
alkali which exists in this salt being preferable.
When the liquid will no longer give a red appearance to paper, the meats
are to be taken out of the bath, as the saturation of the acid is complete.
Then take boiled water and put some common salt into it; when cool, filter it,
and put the meats, prepared as above, into vessels containing the salt and
water, and seal them hermetically:
Although fish may be preserved in the same manner with tartaric acid, it
will be found preferable to use a bath of hydrochloric acid at a temperature of
about three degrees, the taste and odour of the acid to be neutralised by
another bath of chlorure of calcium, then washed carefully with plenty of sca
water, and allowed to dry.
Fruits may also be preserved by the use of tartaric acid or cream of
tartar.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Joseph Hughes in the Great Seal Patent Office on
the 26th August 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
JOSEPH HUGHES, of the Firm of Hughes and Son, Patent Agents, 128,
Chancery Lane, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of March, in the year of our Lord One
thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Edward Joseph Hughes, my executors, administrators, and
assigns, Her special licence that I, the said Edward Joseph Hughes, my
executors, administrators, and assigns, or such others as I, the said Edward
Joseph Hughes, my executors; administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,

page_text: use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN PRESERVING ANIMAL FOOD, POULTRY, GAME, FISH, FRUIT, AND OTHER
SIMILAR SUBSTANCES," a communication from abroad by Edouard Gorges, of
Paris, upon the condition (amongst others) that I, the said Edward Joseph
Hughes, by an instrument in writing under my hand and seal, 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 Edward Joseph Hughes, do hereby
declare the nature of the said Invention, and the manner in which the same
is to be performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
To preserve animal food, poultry, and game in their natural, state, they
must be immersed for about one or two hours, according to the quantity to be
operated upon in a bath of tartaric acid at about five degrees of temperature;
or instead of the tartaric acid, tartrate acid of potassium may be used. The
taste of the acid may be neutralised by a second bath of bicarbonate of
sodium; the pliosphate of sodium will be a good substitute for the alkali, the
free alkali which exists in this salt being preferable.
When the liquid will no longer give a red appearance to test paper, the
meats are to be taken out of the bath, as the saturation of the acid is
complete. Then take boiled water, and put some common salt into it; when
cool, filter it, and put the meats, prepared as above, into vessels containing the
salt and water, and seal them hermetically.
Although fish may be preserved in the same manner with tartaric acid, it
will be found preferable to use a bath of hydrochloric acid at a temperature of
about three degrees, the taste and odour of the acid to be neutralised by
another bath of chlorure of calcium, then washed carefully with plenty of sea
water, and allowed to dry.
Fruits may also be preserved by the use of tartaric acid or cream of
tartar.
Having thns fully described the nature of the said Invention, as commu-
nicated to me from abroad by the said Edouard Gorges, of Paris, and the
manner in which the same is to be performed, I desire it to be distinctly
understood that I do not confine myself to the precise details herein set forth,

page_text: às such may be varied or modified without departing from the principle
thereof; but I claim the preserving of animal food, poultry, game, fish, fruit,
and other similar substances, as herein described.
In witness whereof, I the said Edward Joseph Hughes, have hereunto set
my hand and seal, this Seventeenth day of August, in the year of our
Lord One thousand eight hundred and fifty-nine.
Signed, sealed, and delivered by the within-
named Edward Joseph Hughes, in the
.presence of
GEO. SEP. HUGHES,

Manchester.
