COMPLETE SPECIFICATION.
Improved Means for Cooling the Air in Cooling-chambers and
the like.
I, HELLMUTH RECHTLIEB STRUCK, of 44 Kurfürstenstr. Berlin, in the
Empire of Germany, Master Mason, do hereby declare the nature of my said
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 a means for cooling the air in closed roonis containing
victuals or beverages to be cooled or preserved. The arrangement is such that the
air in the chamber cannot come in direct contact with the ice or other cooling
medium, as experience has shown that air charged with moisture tends to spoil the
articles, notwithstanding the low temperature in the chamber.
According to this invention, tubular bodies for receiving a mixture of salt and
ice, or other cooling agent, are so arranged in the cooling chamber that their upper
ends communicate with a feeding receptacle common to all, and their lower ends
with outlet pipes likewise common to all, for carrying off the drip water from the
ice. The feeding receptacle is preferably arranged so that the ice can be put into
the receiving tubes without opening the cooling-chamber proper; the outlet pipes
are also preferably provided with air-seals for preventing any air finding access to
the chamber. It is also found advisable to furnish the receiving pipes with slides
or the like, in order that one or more of the series may be closed as desired
according to the cooling surface required.
In order that my invention may be thoroughly understood I have illustrated on
the accompanying drawing, by way of example, the arrangement of the device in
an oblong cooling-chamber, Fig. 1 being a vertical section on line y-y of Fig. 2
and Fig. 2 a horizontal section on line -- of Fig. 1.
The cooling-chamber is preferably made with double walls a a, between which is
placed a suitable insulating material such as ashes, ground slag, or the like.
The chamber is closed on all sides and is provided with a tightly-closing door c.
If necessary, easily-closable orifices d may be made near the top of the chamber
for admitting fresh air; it will, however, in most cases be found that the air in the
chamber is sufficiently renewed by merely opening the door c. Near the top of the
chamber are provided tubular bodies or receptacles l, which preferably incline
somewhat towards their closed ends, the other ends being made accessible through
tighly-closing doors or covers fin the walls of the chamber. The receptacles e are
provided with connections g for securing same to a series of vertically-arranged
tubes h, whose upper ends have corresponding flanges for permitting of their ready
attachment to the receptacles e. The ice, or mixture of salt and ice, put through
the doors into the receptacles e thus falls into the tubes h. The latter are
provided near their flanges, or at any other suitable part, with slides i, by means
of which one or more of the tubes h can be closed as desired i.e. so that the ice cannot.
fall into same.
The lower ends of tubes have gratings for supporting the ice; such ends.
also taper as shown at 1 Fig. 1 and finally communicate with the pipe n common to
all, for carrying off the water dripping from the ice. Traps o are arranged in the
pipes n for preventing the outer and warmer air finding its way into same, and this
without interfering with the flow of the water from the melted ice.
In order that any sediment from the melted ice may be readily removed from.

page_text: the pipes h, a sediment-catcher may be suitably arranged in connection with
such pipes. and thus no dirt or the like can pass into and stop the pipes n.
It will be evident that the number, shape and size of the pipes h will differ
according to the size and shape of the cooling-chamber and the particular purpose
for which the latter is intended. It is, however, preferable to arrange same along
the walls of the chamber and to connect the drip water pipes n.
Any suitable
material which does not readily corrode, may be used for the feeding pipes h.
Their arrangement is preferably such that they offer the largest possible superficial
area or cooling surface and thus better fulfil their functions of cooling the air in
the chamber.
It will also be evident that the pipes may be provided with flanges or the
like for supporting shelves on which the articles to be cooled or preserved may be
placed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
A means for cooling the air in cooling chambers and the like, comprising a
series of receiving pipes (h) preferably provided with gratings (k) and slides (i) and
communicating at their upper ends with receptacles (e) preferably fed from without
the cooling-chamber, and at their lower ends with pipes (n) for carrying off the
drip-water, substantially as described and shown in the drawing.
