Improvements in Safes or Receptacles for Storing Meat and other
Comestibles.
We, HERBERT CASTLEDINE RUSHTON, Student, and THOMAS HENRY RUSIITON, Piano
and Organ Factor, both of 34 Cleethorpe Road, Grimsby, in the County of Lincoln, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide ready means for keeping the contents
of safes or receptacles for storage meat and the comestibles cool in hot weather.
For this purpose the whole or part of the sides, top and bottom of the safe or other
receptacle is provided with double walls consisting of cells, or spaces through which water
is caused to circulate preferably on its way from the house main or supply cistern
the ordinary draw-off taps, by which means the cool water is more or less frequently
changed and the internal faces of the safe are consequently kept cool. The external
surfaces of the double walls of the safe may be clothed or coated with any suitable
non-conducting material. Or in some cases coils of pipes may be employed in place
of the double walls or cells of the safe. A bye pass is preferably provided to enable
the water supply to be shut off from the safe during cold weather for example. In
order to produce a current of air through the safe, suitably placed inlet and outlet
openings may be made and if desired a gas or lamp flame may be employed in
connection with the outlet or outlets to assist such in the production of such current
of air.
6 Improvements in Safes or Receptacles for Storing Meat and other
Comestibles.
We, HERBERT CASTLEDINE RUSHTON, Student, and THOMAS HENRY RUSHTON, Piano
and Organ Factor, both of 34 Cleethorpe Road, Grimsby, in the County of Lincoln,
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 to provide means for keeping the contents of safes
or receptacles for storing meat and other comestibles, or other articles, cool in hot

page_text: weather or in a heated atmosphere, in a simple, ready and economical manner
without the employment of ice, chemicals, pumps or other special mechanical devices.
In the accompanying drawing is illustrated an isometrical view of a sale con-
structed in accordance with this invention. The sides A, top B, bottom C, back D,
and door E, of the safe are constructed of double walls of metal or other suitable
material, which form cells or spaces, on all sides of the safe. These cells or spaces
may be provided with auy desired number of partitions or distance pieces-as F for
example for the proper support and strengthening of the sides, etcetera. ti is a
water pipe, which may be the ordinary water service pipe which conducts water from
the main, or from the supply cistern, to the various draw-off taps in the house. This
pipe G is furnished with two stop valves H and I and is connected with the
bottom C of the safe by two other valves J and K. Communication between the
cells of the door E of the sale and the cells of the wall A may be made by means of
a short piece of india-rubber or other flexible tube P secured to nipples Q, 1, thus
permitting the door to be opened and closed without interrupting communication
between the walls of the safe and the door. Or the door may be provided for the
same purpose with a tubular coiled spring, or hollow hinges on the principle of the
well-known swivel-jointed gas-bracket.
When it is not required to cool the safe the valves J and K are closed, and the
valves H and 1 opened. The water will then flow as usual (as indicated by the plain
arrows) from the inain or cistern to the ordinary draw-off taps of the house. But
when it is required to cool the safe the valve 1 is closed and the valves J and K
opened. The water will then flow (in the direction indicated by the feathered
arrows) through the cells of the safe, and finally out through the valve K and away
to the draw-off tap of the house. The temperature of the interior of the safe is thus
reduced approximately to that of the water from the main or cistern, and every time
water is drawn off for household purposes the water in the cells of the safe is changed
and the interior of the safe is thus kept at a low temperature without waste of water,
and without any further attention after the valves have once been regulated. In order
to avoid excessive pressure in the cells of the walls of the safe without interfering
with the proper circulation of water the valve I may, if desired, be only partially
closed so that a certain quantity of water shall be allowed to pass through. Or a
safety valve may be substituted for the valve I, which safety valve shall be arranged
to open as soon as a certain predetermined pressure is exceeded. In order to empty
the hollow walls of the safe, as would be desirable in frosty weather for example, the
valve H may be closed and the valves I, J, and K opened, when the water could flow
away by one of the draw-off taps of the house. But if the levels of such draw-off taps
will not permit of this, one or more small draw-off taps may be provided in the
lowest part of the safe for this purpose. The interior of the sale may be fitted with
removable shelves, as at L, or otherwise, and the exterior surfaces of the safe may be
clothed or coated with felt, wood, cork, or any suitable non-conducting material.
In some cases, more especially where the pressure of water is excessive, coils of
pipes may be employed in place of the double walls or cells of the safe.
In order to ventilate the safe, openings, such as M for example, may be made in
the lower part of the safe for the inlet of air, and one or more openings, such as N
for example, in the upper part of the safe, for the outlet of air. A gas or lamp flame O
may be employed if necessary for the purpose of inducing a continuous current of
air through the safe.
It will be understood that the partitions or distance pieces F not only serve to
support and strengthen the hollow walls, but may also be utilised for regulating the
proper circulation of the water or other liquid.
It is also obvious that the circulating water or other liquid may be employed for
either raising or reducing the temperature of the interior of the safe. For example
if hot water be circulated the improved safe might be employed for airing household
linen, warming plates, dishes etcetera.
The safe may likewise be adapted for use as a burglar-proof and fire-proof safe
for preserving the contents thereof from the action of fire, the construction of the

page_text: safe being suitably strengthened, the ventilating openings M, N, and gas or other
flame O dispensed with, and the water space provided with a relief or escape valve
for the escape of steam when the safe is subjected to excessive heat. Or instead of
a relief or escape valve a tube may be carried from the water space up to a suitable
level for the same purpose.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
First. A safe or receptacle for storing meat and other comestibles or other
articles the walls of which safe, are cellular or hollow, and furnished with devices
for the inlet, circulation, and exit of water or other cooling or heating liquid
therein, with or without relief, escape and ventilating devices, substantially as
described, and for the purposes specified.
Second. A safe or receptacle for storing meat and other comestibles or other
articles the walls of which safe, are cellular or hollow and furnished with devices
for causing the ordinary domestic hot or cold water supply to circulate therein,
substantially as described, and for the purposes specified.
