IMPROVEMENTS IN PRESERVING MEAT
Year: 1880

page_text: LETTERS PATENT to William Clarke Marshall, of the City and State of New
York, but temporarily of Chancery Lane, in the County of Middlesex, for an
Invention of "IMPROVEMENTS IN PRESERVING MEAT."
PROVISIONAL SPECIFICATION left by the said William Clarke Marshall

PRESERVING MEAT."
"IMPROVEMENTS IN
This Invention consists in a new and improved process for preserving meat by
first curing the same, then cooking it, then packing the same in bladders or
intestines, then exposing the packages to pressure for the purpose of expelling the
moisture still remaining in the meat, and finally in drying the packages by smoking
or otherwise.
In carrying out my Invention I first subject the meat to the action of salt,
saltpetre, sugar, or any other of the ordinary autiseptics used for curing meats.
After having been cured the meat is thoroughly cooked by the direct action of fire
or by steam.
I then take the bladders or large intestines (previously well cleaned) of an ox or
a hog and fill them with the cured and cooked meat, packing it closely, after which
the bladders or intestines are securely tied.
The packages of meat thus formed are next subjected to heavy pressure, which
has the effect of eliminating from the meat all or a large proportion of the water
which has not been expelled by the process of cooking, and which it is necessary
Under this
to remove as the water is the active agent in producing putrefaction.
treatment the water is forced out through the pores of the bladders or intestines
which contain the cured and cooked meat.
After this pressing operation has been completed the packages are removed to a
smoking chamber and thoroughly dried by the action of smoke or otherwise. Or
they may be dried by currents of air, after which they are packed and may be
safely shipped to any climate.
I am aware that meat has heretofore been cooked and packed in cans; also that
raw meat has heretofore been packed in bladders or intestines of animals, and
cooked after having been thus packed. By this process, however, the bladders are
made tender, and a large proportion of the water of the meat remains in the
bladder, so that the meat will not keep sweet for any length of time, and is totally
unfit for shipment to foreign climates. By my process, however, an entirely
new article of commerce is created which will keep perfect for a long time.

"IMPROVEMENTS IN PRESERVING
This Invention consists in a new and improved process for preserving meat by
first curing the same, then cooking it, then packing the same in bladders or
intestines, then exposing the packages to pressure for the purpose of expelling the
moisture still remaining in the meat, and finally in drying the packages by smoking
or otherwise.
In carrying out my Invention I first subject the meat to the action of salt,
saltpetre, sugar, or any other of the ordinary antiseptics used for curing meats.
After having been cured the meat is thoroughly cooked by the direct action of fire
or by steam.
I then take the bladders or large intestines (previously well cleaned) of an ox or
a hog and fill them with the cured and cooked meat, packing it closely, after which
the bladders or intestines are securely tied.
The packages of meat thus formed are next subjected to heavy pressure, which
has the effect of eliminating from the meat all or a large proportion of the water
which has not been expelled by the process of cooking, and which it is necessary
to remove as the water is the active agent in producing putrefaction. Under this
treatment the water is forced out through the pores of the bladders or intestines
which contain the cured and cooked meat.
After this pressing operation has been completed the packages are removed to a
smoking chamber and thoroughly dried by the action of smoke or otherwise. Or
they may be dried by currents of air, after which they are packed and may be
safely shipped to any climate.
I am aware that meat has heretofore been cooked and packed in cans; also that
raw meat has heretofore been packed in bladders or intestines of animals, and
cooked after having been thus packed. By this process, however, the bladders are
made tender, and a large proportion of the water of the meat remains in the
bladder, so that the meat will not keep sweet for any length of time and is totally
unfit for shipment to foreign climates. By my process, however, an entirely
new article of commerce is created, which will keep perfect for a long time.
Having now described the nature of my Invention of "Improvements in
Preserving Meat" and explained the manner of carrying the same into effect, I
wish it to be understood that under the above in part recited Letters Patent I
claim,―
First. The process for preserving meat, substantially as herein described, consisting
of the following operations, first, curing the meat, then cooking the same, then
packing it in bladders or intestines, then exposing the packages to pressure, and
finally drying said packages, as set forth.
Second. The process for preserving meat, substantially as herein described,
consisting of the following operations, first, curing the meat, then cooking the same,
then packing it in bladders or intestines, substantially as set forth.
Third. The process for preserving meat, substantially as herein described,
consisting of the following operations, first, curing the meat, then cooking the same,
then packing it in bladders or intestines, and then exposing the packages to
pressure, substantially as set forth.

first, cooking the meat, then packing it in bladders or intestines, and finally
exposing the packages to pressure, as set forth.
In witness whereof, I, the said William Clarke Marshall, have hereunto set my
hand and seal, the Thirteenth day of November, in the year of our
Lord One thousand eight hundred and eighty.
