PROVISIONAL SPECIFICATION.
An Apparatus for Cooling the Air in Cooling Boxes or Refrigerators.
I, FRANCIS FAYOD, Engineer, of 39 Rami Strasse, Zurich, in Switzerland, do
hereby declare the nature of this invention to be as follows:-
The refrigerators now in use for cooling articles of food can only be employed in
places where ice in large quantities can be had cheaply, and in order to have a
substitute for these kind of refrigerators in hot climates and such places where ice
is not obtainable, the herein mentioned cooling-box has been invented which is
worked with cold water, it is supposed that by some contrivance a sufficient
quantity of cold water can be had. The known water spray instrument or syringe
is employed to put the air, enclosed in the cooling box, in motion and to cool it, by
bringing the air in repeated contact with the cold water sprays, whereby the air
imparts its heat to the water which then flows off.
The cooling box has two walls, the outer one consisting of wood and the inner one
of galvanized tin. Between the two walls a space is left, which is filled up with a
non-conducting material of heat. The door which closes the box airtight from the
outside is constructed in the same manner. Inside the box on one of the side walls,
a water spray ventilator is placed, consisting of a bent pipe into which, accessible by
a small door, one of the known water spray instruments is fastened. The spray
instrument is supplied with cold water, by a water pipe from outside. A syphon
conducts the waste water from the pipe to the outside. If the spray instrument is
set into activity, the air in the cooling box in consequence of the sucking propensities
of the descending water mist, enters the pipe at one end and escapes again at the
other end into the box.
The air consequently circulates constantly inside the box and is cooled by coming
into contact with the cold water.
In most cases the air can be kept at such a low temperature which is sufficient to
conserve articles of food.

COMPLETE SPECIFICATION.
An Apparatus for Cooling the Air in Cooling Boxes or Refrigerators.
I, FRANCIS FAYOD, of 39 Rami Strasse, Zurich, in Switzerland, 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:-
My invention relates to an apparatus for cooling.
The refrigerators now in use for cooling articles of food can only be employed in
places where ice in large quantities can be had cheaply, and in order to have a
substitute for these kind of refrigerators in hot climates and such places where ice
is not obtainable the herein mentioned cooling box has been invented, which is
worked with cold water, it is supposed that by some contrivance a sufficient
quantity of water can be had. The known water spray instrument or syringe is
employed to put the air, enclosed in the cooling box, in motion and to cool it by
bringing the air in repeated contact with the cold water sprays whereby the air
imparts its heat to the water which then flows off.

page_text: In the accompanying drawing, Figs. 1, and 2, represent a longitudinal and
lateral section of a cooling box of the herein mentioned invention.
The cooling-box has double walls, the outer one consisting of wood A and the
inner one of galvanized tin B. Between the two walls a space is left, which is
filled up with a non-conducting material of heat. The door D which closes the box
airtight from the outside, is constructed in the same manner.
The box is divided by a partition C into two parts but in such a way that the
partition C does not touch the galvanized tin wall B but leaving room enough that
the air can go from one part into the other.
Inside the box on one of the side walls a water spray ventilator is placed,
consisting according to the drawing, of a bent pipe into which accesable by a
small door, one of the known water spray instruments a is fastened. The spray
instrument is supplied with cold water, by a water pipe a' from outside. A syphon a²
conducts the waste water from the pipe to the outside. If the spray instrument a,
is set into activity, the air in the cooling box in consequence of the sucking
propensities of the descending water mist, enters the pipe bat b¹ and escapes again
at 62 into the box.
The air consequently circulates constantly inside the box and is cooled by coming
in contact with the cold water.
In most cases the air can be kept at such a low temperature which is sufficient to
conserve articles of food.
The box, however, may also be furnished with ice receptacles or may have a
cooling chamber (as described in Patent No. 11932 of 1890), which in a small form
is built inside the box in addition to the pipe b b².
The renewal of the air in the box is obtained by opening the slide E which may
be constructed in any form, or the box may have two small openings, one being
higher than the other, so that a change of air is effected, all contrivances as usual
with refrigerators.
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
1. The combination of the apparatus for cooling, substantially as herein described
and according to the accompanying drawing.
2. The arrangement of a refrigerator where the enclosed air is kept in circulation
by a water spray ventilator and is cooled by coming in constant contact with the
cold water sprays, substantially as herein described.
