The improvements consist in leading or driving a current of air through a
chamber surrounded with ice and fitted internally with strips or plates so arranged
that the current of air is spread or dilated into numerous branch currents which
pass in zig-zag lines through the chamber, the walls of the chamber and the strips
being coated with cotton or cotton wick, or other coarse woved material of large
capillary power. Above the strips perforated gutters are arranged, filled with ice,
from which water drops on to and is absorbed by the material covering the
strips.

material..

The improvements consist in leading or driving a current of air through a
chamber surrounded with ice, and fitted internally with strips or plates so arranged
that the current of air is spread or dilated into numerous branch currents which
pass in zig-zag lines through the chamber, the walls of the chamber and the strips
being coated with cotton or cotton wick, or other coarse woven material of large
capillary power. Above the strips perforated gutters are arranged filled with
ice, from which water drops on to and is absorbed by the material covering the
strips.
The chamber and strips may be made of wood or metal, or of any convenient
material.
In the accompanying Drawing Fig. 1 shows a plan, and Fig. 2, an elevation of a
refrigerator as employed for cooling beer.
B is in this case a horse-shoe shaped vessel surrounded with ice D and E, and
fitted internally with an arrangement of strips or plates a, a, of wood, tinned iron,
zinc, or other suitable material lined with felt or cotton, coarse woven fabrics, or
any other material of great capillary power to present to the evaporating liquid
the largest possible surface; G is a perforated gutter placed inside and at the top
of the vessel B, and filled with pieces of ice or supplied with water; A is a pipe,
through which a current of air produced by any convenient means is directed into
and through the vessel B. The strips or plates a, a, force this current of air
to pass in a zig-zag line along the said evaporating surfaces, a part of the current
'being employed to melt the ice in the gutter G.
The ice water formed in the vessel B may be let off through a cock, while
another cock serves to let off the ice water from the vessel F, into which the
vessel B and the ice are placed. The cooled air, after having passed through the
vessel-B, is directed through the pipe-G into the room to be cooled.
In the example illustrated the air goes through the branch pipes H into the
vessels K, floating upon the beer in the tuns M; J, J, are cocks for regulating the.
admission of air, and L, L, outlet pipes for the exhausted air.
By means of this apparatus air of 70 degrees Fah. may in a few seconds be
cooled down to a temperature near the freezing point.
The above described refrigerator may be varied according to its purpose without
departing from the substance of the Invention, but what I claim is,―
1st. The method of cooling or refrigerating air, liquids, food, or other substances"
by forcing a current of air or other suitable gas over and along rough evaporating
surfaces moistened with water, ether, alcohol, or other liquids, which surfaces are
surrounded with ice in such a manner that the current of air does not come in
contact with the ice, so that the resulting refrigeration is not obtained.merely by
evaporation, nor merely by the ice, but by the mutual effect of these two agents,
substantially as set forth.
2nd. A refrigerating apparatus consisting in a vessel fitted internally with strips
or plates covered with coarse weavings or other material of great capillary power,
maintained in a moist state and arranged in zig-zag lines in combination with a
current of air or other suitable gas'forced through the interior of the said vessel,
the whole being surrounded with ice, substantially as described and shown in the
annexed Drawing.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal. this this Seventh day of March. A.D. 1879.
