IMPROVEMENTS IN PREPARING THE CARCASES OF PIGS AND OTHER ANIMALS FOR CURING
Year: 1864

page_text: LETTERS PATENT to Joseph Strangman Richardson, of Waterford, Ireland,
for the Invention of "IMPROVEMENTS IN PREPARING THE CARCASES OF PIGS
AND OTHER ANIMALS FOR CURING."
Sealed the 30th September 1864, and dated the 7th April 1864.
PROVISIONAL SPECIFICATION left by the said Joseph Strangman
Richardson at the Office of the Commissioners of Patents, with his
Petition, on the 7th April 1864.
I, JOSEPH STRANGMAN RICHARDSON, of Waterford, Ireland, do hereby declare
the nature of the Invention for "IMPROVEMENTS IN PREPARING THE CARCASES
OF PIGS AND OTHER ANIMALS FOR CURING," to be as follows:-
This Invention has for its object improvements in preparing the carcases of
pigs and other animals for curing. In preparing the carcases of pigs and
other animals for curing it is important that they should after death be cooled,
and their surfaces dried as speedily as possible.
Now my Invention consists in subjecting the carcases of pigs and other
animals to streams of atmospheric air artificially produced, in order to cool
and set the flesh, and to carry off the natural moisture from the surfaces.
For these purposes an enclosed building, room, or chamber is used, having a
perforated floor, or perforated pipes, or other channels on the floor, or other
parts thereof, to permit streams of fresh air to be forced into the room by a
fan or other blowing apparatus. Openings are also formed at the upper or

page_text: other parts of the building, room, or chamber, to admit of the free passage away
of the atmosphere from the building, room, or chamber as fresh streams of air
are forced into it by the fan or other blowing apparatus. Or in place of forcing
the fresh atmospheric air into the building, room, or chamber, a like effect
may be produced by withdrawing the air therefrom by means of a fan, or
other apparatus, the outer air being permitted to pass into the building, room,
or chamber by numerous perforations or small passages through the floor, or
other parts thereof, or through perforated pipes or other conduits. The fresh
atmospheric air thus applied through numerous small passages may be taken
direct from the outer atmosphere, or it may be cooled by the use of ice or
other means, or the air may be deprived of its moisture, and in some cases
may be dried or heated, particularly when there is much damp in the atmo-
sphere. Gases of an antiseptic character may be employed in addition to
the supply of atmospheric air for cooling, and for the purpose of preventing
decomposition. As soon as the animals are killed the carcases are suspended
in the building, room, or chamber, and subjected to the action of a quickly
changing atmosphere till the flesh is cooled and set and the surfaces dried,
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Joseph Strangman Richardson in the Great Seal Patent
Office on the 7th October 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
STRANGMAN RICHARDSON, of Waterford, Ireland, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of April, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-seventh year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Joseph Strangman Richardson, Her special licence that I, the said Joseph
Strangman Richardson, my executors, administrators, and assigns, or such
others as 1, the said Joseph Strangman Richardson, my executors, adminis-
trators, 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 PREPARING THE CARCASES OF PIGS AND OTHER ANIMALS FOR
CURING," upon the condition (amongst others) that I, the said Joseph Strang-
man Richardson, ny executors or administrator, by an instrument in writing

page_text: 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 Joseph Strangman Richardson, do hereby
declare the nature of the said Invention, and in what manner the sanie is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention has for its object improvements in preparing the carcases of
pigs and other animals for curing. In preparing the carcases of pigs and
other animals for curing it is important that they should after death be cooled,
and their surfaces dried as speedily as possible.
Now my Invention consists in subjecting the carcases of pigs and other
animals to streams of atmospheric air artificially produced, in order to cool
and set the flesh, and to carry off the natural moisture from the surfaces.
For these purposes an enclosed building, room, or chamber is used, having a
perforated floor, or perforated pipes, or other channels on the floor, or other
parts thereof to permit streams of fresh air to be forced into the room by a
fan or other blowing apparatus. Openings are also formed at the upper or
other parts of the building, room, or chamber to admit of the free passage
away of the atmosphere from the building, room, or chamber as fresh streams
of air are forced into it by the fan or other blowing apparatus. Or in place
of forcing the fresh atmospheric air into the building, room, or chamber, a
like effect may be produced by withdrawing the air therefrom by means of a
fan or other apparatus, the outer air being permitted to pass into the building,
room, or chamber by numerous perforations or small passages through the
floor, or other parts thereof, or through perforated pipes or other conduits.
The fresh atmospheric air thus applied through numerous small passages may
be taken direct from the outer atmosphere, or it may be cooled by the use of
ice or other means. One method of cooling the air to be forced or drawn
through such building is to cause the air to pass through tubes surrounded by
cold pickle, or it may be ice; or the air may be deprived of its moisture by
being passed through or over the surface of lime, or other material having an
affinity for moisture, and in some cases may be dried by being heated, par-
ticularly when there is much damp in the atmosphere. Gases of an antiseptic
character, such as sulphurous acid gas, or nitrous acid gas may be employed
in addition to the supply of atmospheric air for cooling, and for the purpose of
preventing decomposition. As soon as the auimals are killed the carcases are

page_text: suspended in the building, room, or chamber, and subjected to the action of a
quickly changing atmosphere till the flesh is cooled and set and the surfaces
dried.
In witness whereof, I, the said Joseph Strangman Richardson, have
hereunto set my hand and seal, this Twenty-first day of September,
in the year of our Lord One thousand eight hundred and sixty-four.
