COMPLETE SPECIFICATION.
Improved Means for Cooling or Refrigerating the Cellars or Premises
of Butchers, Fishmongers, and the like; also for Cooling or
Refrigerating Railway Cars, Wagons, Ships' Holds, and all other
Premises or Receptacles.
I, DAVID BURNESS WALKER, Poynernook Road, Aberdeen, Fish Curer, do here-
by 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 improved means for cooling or refrigerating the cellars
or premises of butchers, fishmongers, hotel keepers and others in which perishable
articles require to be stored or in which business requiring a low temperature is
carried on.
The said means are also applicable for cooling or refrigerating rail-
way wagons, ships' holds and the like and for any other cooling purposes required.
In accordance with my invention I employ a series of pipes arranged in rows
around the walls or sides of the cellar, room or receptacle to be cooled and con-
nected to a tank situated either within or outside of the chamber to be cooled.
This tank is filled with ice and salt or other refrigerating chemicals which, gradu-
ally melting, result in a fluid. This fluid is led into the series of pipes, which
being circular present a large cooling surface to the surrounding air. The cooling
is thus effected in a simple and efficient manner and with a moderate initial
outlay.
But in order that my said invention may be more readily understood and easily
carried into effect I will proceed to describe with reference to the accompanying
drawings in which.
Fig. 1 is a sectional elevation, and
Fig. 2 an end elevation, also on section, of a railway car, shewing my improve-
ments applied thereto.
Fig. 3 is a sectional elevation of a ship's hold similarly fitted.
Referring to Figs. 1 and 2 of the said drawings
first thoroughly insulate the
inside of the wagon and then secure thereto in any convenient manner, a number
of rows of pipes A fitted with return ends a so that the liquid flowing from the
tank B, which is situated at or above the level of the uppermost row of pipes,
can circulate therethrough.
The number of pipes employed, as also the capacity of the tank, may be varied
to suit different requirements. A tube, not shewn, may also be led from the lower-
most row of pipes to the tank above so that the contents of the pipes can be
pumped back into the tank when the cooling medium is not required, suitable
taps or cocks being provided and situated at convenient positions for preventing
the fluid again flowing into the pipes, and also for draining the pipes if desired.
In the case of railway cars having side doors, as shewn, two tanks may be
employed each provided with a separate series of pipes independent of the other.
The pipes of each series extend from the door at the one side to the end of the
wagon, along the end and back to the door at the other side.

page_text: Suitable manholes or covers may be fitted on the top of the tank by which the
freezing materials can be introduced.
Fig. 3 shews a ship's hold fitted in a similar manner to the railway wagon, the
tank B however being situated outside of the hold, that is to say, on the other
side of the bulkhead C. It may however as in the case of the wagon, be situated
within the hold if found convenient.
The foregoing serve as examples of how the cooling may be effected and the
same or similar arrangement may be employed for household purposes such as
cooling cellars and the like or for any other purpose which it may be desired.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is;-
$
The improved means for cooling or refrigerating the cellars or premises of
butchers, fishmongers, and the like also for cooling or refrigerating railway cars,
wagons, ships' holds and all other premises or receptacles, consisting of a number
of rows of pipes for receiving the cooling fluid from a tank or tanks containing
freezing materials, arranged substantially in the manner as hereinbefore described
and shewn in the accompanying drawings.
