PROVISIONAL SPECIFICATION.
Improvements in Cold Stores.
We ALEXANDER WILLIAM SHAW of Mulgrave Street Limerick in the County of
Limerick Provision Dealer, and ADOLPH GOTHARD CHRISTIANSEN of 14 Upper
William Street Liverpool, in the County of Lancaster, Engineer, do hereby declare
the nature of this invention to be as follows:-
The invention relates to stores for abstracting the animal heat from and maintaining
at a sufficiently low temperature by mechanical means the carcases of hogs and other
goods of a perishable nature so as to preserve them from decay.
The object is to so construct and equip such stores that the requisite temperature
is readily obtained and maintained without undue expenditure of power.
For the above purpose we construct such stores of walls protected by non
conducting material in any usual way and we arrange pipes or tubes through which
refrigerating fluid is caused to flow at or above the top of the said stores, and further
we provide partitions of non-conducting material so disposed as to cause a circulation
of air within the said store from the bottom upwards.
Under one modification the pipes or tubes are placed in a shaft extending above the
top of the store with vertical partitions extending down near to the bottom of the
store. In a second modification the pipes or tubes are placed along the top of the said
store with horizontal partitions extending beneath the said pipes or tubes and at one
end with vertical partitions carried down to near the bottom of the store.
Any suitable refrigerating machinery say such as ammonia absorption or other
machinery is used to reduce the refrigerating liquid which is caused to pass through
the pipes or tubes to the required temperature.
The store is provided with air tight non conducting doors and with drain pipes and
moisture collecting receptacles.

Wo ALEXANDER WILLIAM SHAW of Mulgrave Street, Limerick, in the County of
Limerick Provision Dealer, and ADOLPH GOTHARD CHRISTIANSEN of 14 Upper
William Street Liverpool in the County of Lancaster, 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 invention relates to stores for abstracting the animal heat from

the top of the said store with horizontal partitions extending beneath the said pipes or
or tubes are placed along

the store.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a vertical section of a cold store under our invention.
the store constructed in any usual way. is a shaft extending above the top of the
a are the walls of
store. c is a vertical partition extending from near the top of the shaft to near the
bottom of the store, & are brine or refrigerating fluid circulation pipes or tubes
between the partition and the cold store wall.
The refrigerating fluid pipes or tubes are arranged and carried in any suitable
way. The partition is of wood or non-conducting material. More than one partition
and set of refrigeration pipes may be used.
Fig. 2 is a vertical section of a modification of cold store in which the pipes or
tubes d are placed horizontally near the top of the store, and in which the partition c
is placed horizontally beneath the pipes and extends down in a vertical direction
close to one of the walls until near the bottom of the store.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
claim is
First. Cold stores fitted with pipes or tubes through which refrigerating fluid is
caused to flow and provided with a partition or partitions for causing circulation of
air through the store from the bottom upwards substantially as set forth.
Second. Cold stores with a shaft b, a vertical partition or partitions c and refri-
geration pipes or tubes d for the purpose set forth.
Third. Cold stores with refrigeration pipes or tubes and a partition or partitions
substantially as set forth under figure 2.
