Fig. 4 is a vertical section through a side portion of the apparatus.
In the following description like letters and figures refer to like letters and figures

An outer casing n, with ventilating chimney m, sundry openings or gratinge for the
ingress of air surrounds the refrigerator proper, which consists of one
boxes a, which are double-jacketed on all sides except the side facing the door x in
the outer casing afore-mentioned. The said outer box n I prefer to make from wood
or other bad heat-conducting material, the bottom part of which 1 generally line
inside for instance with zinc of which I likewise prefer to make the internal box or
boxes a.
The internal part of the said double-jacketed box or boxes a, is meant to hold the
articles to be kept cool, and is sometimes divided into several compartments preferably
by means of double-jacketed partitions, the internal sides of box a being then broken
through in order that liquor contained in the jacket surrounding the box may also
have access to the partition-jacket y Fig. 3.
The lower box or boxes a do not rest full on the bottom of the outer box n but is
elevated somewhat from the bottom so that an empty space B (Fig. 2) is formed,
issuing from which a number of vertical tubes f pass through the jacket c reaching
nearly to the lid of the outer casing n, or at all events above the highest water level
when the jacket c is assumed to be filled with water.
The said tubes are soldered water-tight where they pass through the bottom of
the jacket c, and wicks or similar absorbing material g are hung over the upper edges
of tubes f, the internal parts of which they cover more or less, dipping into the
water that must be assumed present in the jacket, points or hooks h being attached
to the upper edges of tubes fin order to prevent the wicks from slipping.
The manner of action is as follows: The jacket c is filled with water which may be

absorbing water from the jacket will become damp throughout their length so that
practically the tubes fare covered inside with damp material, and consequently the
up-draught caused by the chimney m and the air ingress through the grating e tends
to evaporate the moisture in the wicks, by which evaporation coolness is created.
The lower space B (Figs. 2 & 3) serves to receive any drippings there may be from
the wicks, while the tap o Fig. 3 serves to empty out any such accumulations. The
tap
h serves to empty the water from jacket c.
The tubes may also be made from porous material, in which case wicks would
not be needed, at the same time I consider wicks to be preferable.

page_text: Having now particularly described and lascertained the nature of my said Inven-
tion, and. in. what manner, the same is to be performed, I declare that what 1
claim is:
In refrigerating chests, boxes and the like the method of creating coolness by
continuous evaporation of water brought about essenthilly by means of tubesy placed
in water and either-made of porous material, or provided with wicks,so as to conduct
inoisture to the internal part of such tubes, through, which air is conducted substan
tially for the purpose-described:..
