I, LOUIS MARX, of Radegast, Anhalt, in the Empire of Germany, Coppersmith,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:-
The object of this invention is a cooling apparatus for dairies and the like
in which the cooling pipes serve at the same time as supports for the material
to be preserved, or a sheet of metal may be placed between the former and the
latter.
The accompanying drawings show one way of carrying out the subject matter
of the invention, Fig. 1 being a perspective view of the cooling apparatus,
while Fig. 2 is a vertical section of the same. Fig. 3 is a horizontal and Fig. 4
a transverse section of the said apparatus. Fig. 5 is a side view of the bottom
plate.
The cooling apparatus is enclosed in a cupboard consisting of insulated walls
which may be made of any suitable material and are double. Between the
same, a non-conducting material such as ashes for instance can be readily piled
up or the interval may remain empty, the air serving then as a non-conductor
of heat. As shown in Figs. 2 and 3′ the cupboard is traversed from top to bottom
by a number of pipes 6. These pipes are placed in close proximity one to
the other at suitable intervals and are connected together by knee joints c. In
one of the knee joints of such a horizontal row, is inserted a vertical pipe d
which in its turn is connected by another knee joint to the following row and so
ou. These vertical pipes d may have any suitable length for the same cup-
board, in order not to occupy too much room for the preservation of different
large articles. Angle irons are fixed to the walls of the cupboard to receive
and support the ends of the pipes of each row or layer. The water runs at e
into the inlet pipe of the lowermost horizontal row and along the pipes until
it reaches its outlet f, whence it is allowed to run out or is utilized for any other
specific purpose. A cock is placed at the outlet f outside the cupboard and
allows the water to run out according to requirements and to be replaced by
the cooling water derived from the water supply pipe. In each household the
necessary water can be obtained from the main supply pipe, and hence the
above described cooling machine will be found the best substitute for ice refri-
gerators. The pipes are preferably made of metal sheets coated with tin or
gine.
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 cooling apparatus for dairies and the like characterized by the arrangement
in a cupboard or the like of a number of horizontal vines & connected together

page_text: by vertical pipes d and resting on angle irons i, so that the water proceeding
from a main supply pipe for instance may run in ate and run out at f being
controlled thereat by a suitable cock g.
