PROVISIONAL SPECIFICATION.
Improvements relating to the Cooling of Refrigerators or Food
Closets, also Applicable to Cooling and Ventilating Dwelling
and other Rooms.
I, EDGAR ALDOUS, of Elmhurst, Forest Gate, Essex, Architect, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an automatic means for cooling the interior of chambers
without the aid of ice or machinery and is particularly suitable for cooling chambers
used for storing articles necessary to be kept cool for preservation, the invention
being also suitable for cooling and ventilating dwelling and other rooms. I have
discovered by my experiments that the best preservative results for articles of food
are obtained by passing a continuous current of cooled air through the preserving
chamber a suitable current I am able to obtain by my invention as hereafter
described.
According to this invention as applied to a food chamber, I construct a water-
tight case preferably of galvanized iron entirely within a second case or jacket formed
of or having the outside coated with a non-conductor of heat, the space between
the case and jacket being arranged to hold water, a suitable door water jacketted as
described, is provided for inlet to interior. This double chamber is placed in the
cellar of a house, provision being made that such cellar has a free inlet of fresh air,
and is free from objectionable smells. The fresh air is introduced into interior of
chamber by an inlet tube preferably flat, passing a certain distance through the water
in jacket and communicating with the interior, by this means the air is cooled before
entering chamber.
The exit for the air is arranged in a somewhat similar way, the
pipe being carried through the water and out into the atmosphere this being warmer
than the interior of the chamber will suck out the cooler air and so automatically set
up a continuous current of cool air through the food chamber. The jacket is fitted
with means for the inlet and exit of the water, which should be put in, in the cold
weather when no further attention will be required for months.
For ventilating and cooling dwelling rooms, the refrigerator chambers will be
arranged in the cellar as described, and the cooled air passed from it through pipe
or pipes into the room; the inlet for the cooled air may be in the middle of the
ceiling, preferably having a spreader or deflector to deflect the current over the room;
the exit from the room for the air may be by the chimney or through an opening in
or near the sur-base connected with pipes passing out into the atmosphere.
Dated this 27th day of August 1889.

Improvements relating to the Cooling of Refrigerators or Food
Closets, also Applicable to Cooling and Ventilating Dwelling
and other Rooms.
I, EDGAR ALDOUS, of Elmhurst, Forest Gate, Essex, Architect, 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 :-
This invention relates to automatic means for cooling the interior of chambers
without the aid of machinery or ice and is particularly suitable for cool chambers used
for storing articles necessary to be kept cool for preservation, the invention being
also suitable for cooling and ventilating dwelling and other rooms. I have discovered
[Pains 1

page_text: that the best preservative results for articles of food are obtained by passing a con-
tinuous current of cooled air through the preserving chamber.
According to this invention as applied to a food chamber, I construct a water
jacketted case, preferably of galvanized iron and coat the outside with a bad conductor
of heat, such as felt. The case is fitted with a suitable door which may also be
water jacketted. A case or chamber made as described is placed in the cellar of a
house, provision being made that such cellar has a free inlet of fresh air, and is free
from objectionable smells. The fresh air is introduced into interior of chamber by
inlet tubes or channels preferably of metal and flat passing a certain distance through
the water in jacket and communicating with interior; the coolness of the water being
imparted to the tubes, causes the air passing through them to be cooled before
entering the chamber. The exit for the air is in the top of chamber, which is carried
through suitable pipe into the atmosphere.
The warmer temperature of the atmosphere will suck up the cooler air from interior
of chamber, and thus set up an automatic continuous current through the chamber.
When this invention is used to cool and ventilate a room, the cooling chamber will
be arranged in the cellar as described, and the cooled air passed from it into the room
through suitable channel; the inlet may be in the middle of the ceiling, preferably
having a spreader or deflector of known form to deflect the current over the room;
the exit from the room may be by the chimney, or in an opening in or near the
surbase connected with pipes passing out into the atmosphere.
To enable my invention to be properly understood I will proceed to describe the
same with aid of the accompanying drawings.
Figure 1. sectional elevation of the cooling chamber.
Figure 2. plan of same on line X. Y.
Figure 3. perspective view.
A is the outer case and B the inner, the inlet channels for the air, D the outlet,
the mouths of these channels are covered with wire guaze E. The interior may be
fitted up with shelves, bottle racks or other conveniences for holding articles of food ;
F the water.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is:
1. A cooling chamber, water jacketted, and having a current of cooled air passing
through, cooled by the water in jacket substantially as hereinbefore described and
illustrated by accompanying drawings.
2. The combination with the cooling chamber herein before described of pipes or
channels to convey the cooled air into a room, as and for the purposes hereinbefore
described.
