PROVISIONAL SPECIFICATION left by the said George Kent at the Office of
the Commissioners of Patents on the 26th March 1877.
GEORGE KENT, of High Holborn, in the County of Middlesex.
IN ICE SAFES AND REFRIGERATORS.'
"
"IMPROVEMENTS
This Invention has for its object improvements in ice safes and refrigerators.
In the Specification of a former Patent granted to me in the year 1808, No. 1469,
I have described a means of ventilating ice safes and refrigerators by the downward
flow of cold air, the ice being placed at the top or near the upper part of the safe or
refrigerator.
According to my present Invention I obtain an efficient ventilation with the ice
in a lower position within the safe or refrigerator, an arrangement which has the
advantages of greater convenience in use, the maintenance of a cooler temperature
in the lower part of the safe or refrigerator, and an economy in ice.
I arrange a pipe to lead from the upper part of the safe or refrigerator where the
air within is warmest, downwards through the bottom, and here it terminates in an
open mouth. This pipe being contained within the safe or refrigerator is kept
constantly cold, and there is hence a tendency for the air to descend through it and
pass out.
Air is allowed to enter the safe or refrigerator by a pipe descending
through the top or other part, and passing to the back of the ice basket, which is
made double; the pipe delivers the air into a cavity within the back, from which
the air is able to issue by perforations and to pass amongst the ice, where the air
already partially cooled in its passage through the descending pipe is further cooled,
and is rendered dry by the deposition of the moisture which it contained upon the
surface of the ice.
It will be seen that by this arrangement the air is drawn out from the part of the

page_text: safe or refrigerator where the warmest and most vitiated air is to be found; the ice
rack also is in a more convenient position for filling than when near the top of the
safe or refrigerator,

page_text: or refrigerator ventilated in the same manner. A is the ice rack; C, the pipe for
admitting air from the outside of the top of the safe to the interior of the ico rack;
its lower end is perforated, as shown, to allow the air to pass amongst the ice in the
rack. D is the pipe by which air is conducted downwards from the upper part of
the interior of the safe,. and allowed to escape from it at the bottom; E is a door in
the front of the safe, through which ice may be supplied to the ice rack or articles
placed into or taken out of the safe.
Having thus described the nature of my Invention and the manner of performing
the same, I would have it understood that I claim, the construction of ice safes and
refrigerators ventilated substantially in the manner herein-before described.
In witness whereof, I, the said George Kent, have hereunto set my hand and
seal, this Twenty-fifth day of September, in the year of our Lord One
thousand eight hundred and seventy-seven.
