PROVISIONAL SPECIFICATION.
I, ALFRED WILLIAM MARSHALL of 30, Mortimer Street Cavendish Square in the
County of Middlesex Tutor do hereby declare the nature of said invention for
"IMPROVEMENTS IN 'ICE CAVES' OR APPARATUS FOR FREEZING SOUFFLÉS AND
MOULDING ICE PUDDINGS AND THE LIKE, ALSO APPLICABLE AS AN ICE SAFE AND
บ to be as
FOR KEEPING FOOD OR DRINK AT A LOW OR HIGH TEMPERATURE
follows:-
"
Up to the present time the moulding of ice puddings and the like has been
effected by using moulds which are made to entirely surround the mixture required
to be made into a shape and to lute with grease or some equivalent every.crack
and joint of the mould and then to place the mould into a pail or tub and surround
the mould with a freezing mixture such as a mixture of ice and salt. By my
Invention I do entirely away with the necessity for specially designed moulds and
avoid the use of grease and prevent all possibility of brine entering the mould.. It
also enables the operator to examine the process from time to time, also enables the
ice when moulded to be kept ready and be turned out for use at any moment and
also to keep or preserve any part of the ice not used.
I provide an internal metal cave or cupboard surrounded by another vessel or
casing so that between the two a layer of ice and salt can be maintained producing
in the internal cave a very low degree of temperature. The casing is formed with
intermediate air space and its exterior part is made of wood or other non-conductor
for protection against atmospheric influence thereby making a cold more intense
and lasting in the inner cave or cupboard in which are put the ice puddings soufflés
or other materials required to be frozen, set in shape or cooled.
The front door of the cave or cupboard is also formed with an interior space for
freezing mixture This space is filled from the top and there closed by a sliding or
other lid. The door is also formed with intermediate air space and its outer face is
wood or other non conductor like the other parts of the casing.
The top of the apparatus is closed by a sliding or other lid covered with wood or
.other non-conductor and by preference formed with intermediate air apace.
"
The joints at the door and at the lids should be kept tight by means of flannel or
the like to exclude the air.

I, ALFRED WILLIAM MARSHALL, of 30, Mortimer Street, Cavendish Square, in
the County of Middlesex, Tutor, do hereby declare the nature of said Invention for
"IMPROVEMENTS IN ICE CAVES OR APPARATUS FOR FREEZING SOUFFLÉS AND
MOULDING ICE PUDDINGS AND THE LIKE, ALSO APPLICABLE AS AN ICE SAFE AND
FOR KEEPING FOOD OR DRINK AT A LOW OR HIGH TEMPERATURE," and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:—
Up to the present time the moulding of ice puddings and the like has been
effected by using moulds which are made to entirely surround the mixture required
to be made into a shape and to lute with grease or some equivalent every crack and
joint of the mould and then to place the mould into a pail or tub and surround the
mould with a freezing mixture such as a mixture of ice and salt. By my invention
I do entirely away with the necessity for specially designed moulds and avoid
the use of grease or other luting material and prevent all possibility of brine
entering the mould. It also enables the operator to examine the process from time
to time, also enables the ice when moulded to be kept ready and be turned out for
use at any moment and also to keep or preserve any part of the ice not used.
Figure 1 of the accompanying drawings is a vertical section through my ico cave,
Figure 2 a horizontal section through the same, Figure 3 a perspective view with
the two parted top lid removed so that the freezing mixture may be put in, and
Figure 4 a perspective view of the apparatus as it will appear when charged and
ready for use. I provide an internal metal cave or cupboard A with one or more
shelves B across if desired, and surrounded by another vessel or casing A*, so that
in the space D between the two a layer of ice and salt can be maintained producing
in the internal cave a very low degree of temperature. An intermediate air space E
is formed between the casing A* and its exterior part C which latter is made of
wood or other non-conductor for protection against atmospheric influence thereby
making a cold more intense and lasting in the inner case or cupboard, in which are
put the ice puddings, soufflés or other materials required to be frozen, set in shape
or cooled. Or if the food or drink is to be kept hot in the cave I charge the spaces D
and D¹ with hot water instead of freezing mixture.
The front door of the cave or cupboard is also formed with double walls A¹and A'
leaving an interior or intermediate space D¹ for freezing mixture. This space is
filled from the top and there closed by a sliding or other lid G₁. The door is also
formed with intermediate air space E' between the wall A² and its outer face or
wall C¹, which latter is of wood or other non-conductor like the other parts of the
outer casing.
The top of the apparatus is closed by a sliding or other lid G made of (or covered
with) wood or other non-conductor and which may also be formed with intermediate
Віг врасе,

page_text: The joints at the door and at the lids should be kept tight by means of flannel
or the like to exclude the air. P and P¹ are plugs for letting out the water from
the compartments D and D¹.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
A freezing cave or ice safe or hot safe consisting of an inner cupboard with hollow
walls A. A and door with hollow walls A¹ A² the intermediate spaces D) and D'
containing freezing mixture (or hot water) and being accessible by lids G and G¹,
the said cupboard and door being provided with outer wall C and C³ and
intermediate air spaces E and E¹ all substantially as set forth.
