I, HERBERT JOHN HADDAN, of 67, Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of said Invention for "AIR-COOLING
APPARATUS, ALSO APPLICABLE FOR COOLING LIQUIDS," a communication to me
from abroad by Georg Honerla, of Kohlstädt, Lippe in the German Empire,
Gentleman, to be as follows:-
:-
This invention relates to apparatus for the production of cold air by means of
ice, or cold liquids flowing in a direction opposite to the air to be cooled.
For this purpose the apparatus chiefly comprises an ice receptacle, with
perforated bottom, a series of superposed sieves situated under the ice receptacle,
an air chamber situated under the sieves, an outlet valve, and a tank for collecting
the ice water which has flown down through the sieves and the air chamber.
The direction of the air current is from the air chamber upward through the
sieves and the ice to the air outlet pipe, and the current may be produced either
by pressure from the bottom or by suction from the top. In the latter case the
vessel enclosing the ice, the sieves and the air chamber is covered by a hermetically
closing lid, and the air chamber is provided with lateral openings communicating
with the surrounding atmosphere.
The water, collected at the bottom of the vessel, may either be let off into the
tank, or admitted through a three way cock to a pump to be lifted again to the
top of the vessel and allowed to fall upon the ice in the form of a spray.
The three way cock may be made to cut off communication between the pump
and the vessel, while admitting cold water to the pump from a suction tank.
Instead of causing the cooling water to pass through a series of sieves, it may
be made to flow in a zig-zag direction over a series of superposed metal plates or
trays secured alternately to the right and left side of the vessel and leaving on
the opposite side a space for the upward flow of the air and downflow of the
water,
The ice receptacle may have a solid bottom and be surrounded at some distance
by a wooden casing, so as to leave an annular space for the upward flow of air
and the downflow of the water which has passed over the upper edge of the
inner vessel.

page_text: Cold water may be introduced into the ice by a pipe terminating near the
bottom of the inner vessel or ice receptacle.
The air pipe, leading from the top of the cooler having a hermetically closing
lid, may be connected with an exhaustor, the discharge pipe of which is conducted
upward through a vat containing liquid to be cooled, and carries at the top
a reaction wheel set in motion by the reaction of air flowing tangentially from
the wheel.
The ice may be mixed with a small quantity of salt; if desired;
The cooler provided with superposed motal plates, instead of sieves, may be
adapted for cooling liquids instead of air, by causing the warm liquid to flow into
the upper tank (corresponding to the ice receptacle, and to fall over the upper
edge of the same into the annular space formed between the tank and its jacket,
and leading down into the space which contains the cooling plates.
The cold air serving to cool the liquid is first led through an inverted syphon
(provided at the bottom with let-off cocks), before entering the bottom of the
couler or the air chamber.
From this latter it flows upwards between the metal plates and through the
annular space (around the liquid tank) into the dome or upper part of the casing
which surrounds-the-liquid tank, the said casing being open at the top, and in the
"shapo of two-truncated-cones-joined together at their base.-

I, HERBERT JOHN HADDAN of 67, Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of said invention for AIR-COOLING
APPARATUS, ALSO APPLICABLE FOR COOLING LIQUIDS, a communication to me
from abroad by Georg Honerla, of Kohlstadt, Lippe in the German Empire, 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 apparatus for the production of cold air by means of
ice, or cold liquids flowing in a direction opposite to the air to be cooled.
For this purpose the apparatus chiefly comprises an ice receptacle, with.
perforated bottoin, a series of superposed sieves situated under the ice receptacle,
an air-chamber situated under tlie sieves, an outlet valve and a tank for collecting
the ice water which has flown down through the sieves and the air chamber.
The direction of the air current is from the air chamber upward through the
sieves and the ice to the air outlet pipe, and the current may be produced either
by pressure from the bottom or by suction from the top. In the latter case the
vessel enclosing the ice, the sieves and the air chamber, is covered by a hermetically
closing lid, and the air chamber is provided with lateral openings communicating.
with the surrounding atmosphere. The water collected at the bottom of the
vessel may either be lot off into the tank, or admitted through a three way cock
to a pump, to be lifted again to the top of the vessel and allowed to fall upon the
ice in the form of a spray.
The three way cock may be made to cut off communication between the pump
and the vessel, while admitting cold water to the pump from a suction tank.
In the accompanying drawings Fig 1 is a vertical section of an air cooling
apparatus supplied with a blast from below, while Fig 2 is a vertical section
of a cooling apparatus through which the air is drawn by suction from the top.
Fig 3, 4 and 5 represent modifications.
A is the main receptacle provided with perforated bottoms a and b. 6 are
perforated inetal plates. d in Fig 1 is the inlet for the air current which takes
the course indicated by an arrow. f is a collecting tank for the ice water, ga
cock for letting off the water from the receptacle A into the tank f, h is a plug in
the bottom of the vessel A,

In Fig 2 the vessel A has an iron cover provided with an inlet for the pipe k¹
and with a fill opening .
m are the lateral openings for the admission of air to the lower part of the
vessel A, n is the air outlet, C an exhaustor drawing the air from n and delivering
it into the pipe o. B is a rotary pump adapted to draw water either from the
bottom of the vessel A, through pipe k, or from an independent cold water supply
tank through pipe k³, and to deliver it through pipe k¹ to the spray producer k³
situated at the top of the vessel A. ' is a three-way cock.
Instead of causing the cooling water to pass through a series of sieves, or
perforated plates, it may be made to flow in a zig-zag direction over a series
of superposed metal plates e¹ Fig 3 or trays secured alternately to the right and
