PROVISIONAL SPECIFICATION.
An Improved Process and Apparatus for Preserving Meat and other
Alimentary Substances.
We, GUSTAVE DOSMOND and FERDINAND ROZES, both of 95, Boulevard
Beaumarchais, Paris, in the Republic of France, Chemists, do hereby declare the
nature of this invention to be as follows:-
-
This invention relates to a process and apparatus for preserving meat and
alimentary substances in general. As compared with the processes heretofore
employed the improved process presents the great advantage of enabling the fresh
appearance of the meat and other substances to be preserved.
The essential feature of the said process consists in placing the alimentary
substances which are to be preserved in a closed chamber, in which the air is
replaced by gases derived from the distillation of charcoal or other materials
capable of yielding carburets and hydro-carburets; these gases being in the said
chamber either with or without pressure.
The apparatus by means of which the aforesaid process is carried into effect
comprises one or more closed retorts placed in a suitable furnace and filled with
carbonaceous material such as charcoal, coal, or the like. From the retort passes
a tube through a refrigerator into a clearing chamber.
0
The gases derived from the distillation of the material contained in the retort
after having passed through the said clearing chamber are conducted into a
receptacle or holder wherein they are collected. From this receptacle or holder as
much of the gas as may be required is conveyed to preserving chambers, by a pump
or other suitable means.
By subjecting alimentary substances to this very simple process which can also
be realized by other apparatus than that above described, they will be preserved
in a remarkable manner.
It has been found that meat taken from one of the above-mentioned chambers
after a certain time of exposure retains the fresh appearance which it had originally
and further that when the meat is cooked the blood contained in the same exudes
like the blood from unpreserved fresh meat. On placing blood in these chambers
it was ascertained that after a long exposure it had not coagulated.
Our process, besides perfectly preserving alimentary substances presents the
advantage of destroying all injurious germs which may be contained therein.
The meat or alimentary substances can be transported by placing them in
waggons or closed receptacles containing carburets or hydro-carburets.
These gases may also be introduced into preserve boxes containing such
alimentary substances.

An Improved Process and Apparatus for Preserving Meat and other
Alimentary Substances.
We, GUSTAVE DOSMOND, and FERDINAND ROZES, both of 95, Boulevard
Beaumarchais, Paris, in the Republic of France, Chemists, do hereby declare
the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to a process and apparatus for preserving meat and

page_text: alimentary substances in general. As compared with the processes heretofore
employed the improved process presents the great advantage of enabling the
preservation of the fresh appearance of the meat and other substances.
The essential feature of the said process consists in placing the alimentary
substances which are to be preserved in a closed chamber, in which the air is
replaced by gases derived from the distillation of charcoal or other materials
capable of yielding carburets and hydro-carburets, these gases being in the said
chamber either with or without pressure.
The apparatus which we employ for carrying the said process into effect is
shown by way of example in the accompanying drawing and comprises one or more
closed retorts A placed in a suitable furnace and filled with carbonaceous
material such as charcoal, coal, or the like. From the retort passes a tube B
through a refrigerator C, into a clearing chamber D.
The gases derived from the distillation of the material contained in the retort-
after having passed through the said clearing chamber D, are conducted into a
receptacle or holder E wherein they are collected. From this receptacle or holder
as much of the gas as may be required is conveyed to preserving chambers by a
pump For other suitable means.
By subjecting alimentary substances to this very simple process, which can also
be realized by other apparatus than that above described, they will be preserved in
a remarkable manner.
It has been found that meat taken from one of the preserving chambers after a
certain time of exposure, retains the fresh appearance which it had originally and
further that-when-the-meat-is-cooked the-blood contained in the same exudes like
the blood from unpreserved fresh meat.
On placing blood in these chambers it was ascertained that after a long exposure
it had not coagulated.
Our process, besides perfectly preserving alimentary substances presents the
advantage of destroying all injurious germs which may be contained therein.
The meat or alimentary substances can be trans ported by placing them in
waggons or closed receptacles containing carburets or hydro-carburets.
These gases may also be introduced into preserve boxes containing such
alimentary substances.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First. The above-described process for preserving meat and other alimentary
substances in a fresh state, characterized specially by exposing the substances to
the action of gases derived from the distillation of charcoal, coal or other material
capable of yielding carburets and hydro-carburets.
Second. For carrying the said process into effect, the apparatus hereinbefore
described and shown in the accompanying drawing.
Third. The transport and preservation of meat and other food substances by
placing them in closed waggons or receptacles or in preserving-boxes containing
the carburetted gases above mentioned.
