PROVISIONAL SPECIFICATION.
Improved Means and Appliances for Preserving Flesh Food.
I, WILLIAM SPEIRS SIMPSON, of 49, Battersea Park Road, Surrey, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is preserving flesh food in a novel manner.
For this purpose and to better illustrate the mode by which one particular part
of the invention is intended to cover, namely, the tinned or canned meat, I propose
to use and preserve meat in a raw, or partly raw condition, so that users of tinned
or canned meat may have it in the raw, or partly raw state, and can therefore cook,
or use the meat, as if it had been cut fresh from the joint, and get all the flavour
and corresponding qualities of taste and effect that is derived from flesh and other
meats in that condition.
The
For the above named system, I use two tins or cans, an inner and outer.
outside.surface of the inner tin or can has projecting flanges or strips of metal on
its sides and ends, so that when it is placed into the outer or larger can or tin, the
flanges or strips fit nicely into the inside of the outer can, and while preventing
shaking or any looseness, it leaves a space between the two tins or cans; such space
is of considerable importance as it forms an insulator for the inner tin or can from
getting effected by the variations of the temperature.
The inner tin or can has by preference an internal netting of wire of a less size
than the tin, so that it has an air or open space of a predetermined area. The
meat is placed into the netting, so that the sides of the can or tin are not brought
into touch with the contents. The lid is then soldered on. There is a small
aperture or tube forming a sort of nozzle fixed in the lid, or at a suitable place in
the tin and an air machine is connected with the nozzle to extract all the original
air and filling the tin with the cold dry air. The nozzle or tube is then pressed
forcibly together and a drop of solder completes the operation.
I then charge the space between the two tins with cold dry air, or I form a
vacuum therein and solder up similar to that of the inner tin.

COMPLETE SPECIFICATION.
Improved Means and Appliances for Preserving Flesh Food.
I, WILLIAM SPEIRS SIMPSON, of 49, Battersea Park Road, Surrey, Civil
Engineer, 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:—
The object of this invention, is preverving food in a novel manner.
For this purpose and to better illustrate the mode by which one particular part
of the invention is intended to cover, namely, the tinned or canned meat, I propose
to use and preserve meat in a raw, or partly raw condition, so that users of tinned
or canned meat may have it in the raw, or partly raw state and can therefore cook,
or use the meat as if it had been cut fresh from the joint, and get all the flavour
and corresponding qualities of taste and effect that is derived from flesh and other
meats in that condition.
For the above named system, of which the annexed drawing represents an

page_text: example, I use two tins or cans A and B, an inner and outer. The outside surface
of the inner tin or can A has projecting flanges or strips C on its sides and ends, so
that when it is placed into the outer or larger can or tin B, the flanges or strips C
fit nicely into the inside of the outer can, and while preventing shaking, or any
looseness, they leave a space D between the two tins or cans A and B.
Said space
is of considerable importance as it forms an insulator for the inner tin or can from
getting affected by the variations of the temperature.
The inner tin or can has by preference an internal netting E of wire of a less size
than the tin, so that it has an air or open space of a predetermined area. The
meat is placed into the netting E, so that the sides of the can or tin A are not
brought into touch with the contents. The lid F is then soldered on. There is a
small aperture or tube G forming a sort of nozzle fixed in the lid, or at a suitable
place in the tin and an air machine is connected with the nozzle to extract all the
original air. I then fill the tin with cold dry air. The nozzle or tube G is then
pressed forcibly together and a drop of solder completes the operation. The tin
and its contents may then be subjected to refrigeration if desired.
I then place the tin A within the outer tin B, and after securing the lid, I charge
the space D between the two tins with cold dry air, or I form a vacuum therein by
attaching the air exhauster to the tube FI and solder up similar to that of the
inner tin.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner, the same is to be performed, I declare that what I
claim is :-
The improved means and appliances herein described and shown for preserving
food (such as meat) consisting essentially of an inner vessel enclosed within an outer
vessel in such a manner as to leave a space between the two all round, said space
being occupied by cold dry air, or a vacuum formed therein to act as an insulating
medium between the outer tin and the tin containing the food to be preserved.
