I, JOSEF TURODOR POPLAWSKY of Bremerhafen, Am Hafen 39/41 Master
Locksmith 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 an apparatus for cooling beer which although
designed in the first instance for the treatment of beer, is likewise applicable for
the treatment of other beverages or of liquids requiring to be cooled to a certain
degree and within given limits.
The chief advantage of this new apparatus is that it can be made of the smallest
as well of the largest size without in any way impairing its efficacy; its action
remaining constant. When this apparatus is required to be used in cellars,
warehouses or in places where accommodation is scanty and crude, the apparatus
can be made in the simplest form and of the cheapest material without affecting
its working capabilities. Yet should the apparatus be required for elegant
restaurants or bars it can be artistically manufactured as regards form as well as
material.
The accompanying drawings show the subject matter of the invention in all its
details, and convey likewise a correct impression of its shape and dimensions.
The three first figures show several views of the apparatus Fig. 1. being a
longitudinal section, Fig. 2. a cross section and Fig. 3a plau corresponding to
Fig. 1.
The casing a which has a rectangular form is divided by a transverse piece b into
two unequal divisions a' and a². Within the largest division a are placed a number
of longitudinal bars c connected together by the transverse bars d and held at
equal intervals from one another by the tube e. The channels ¹ƒ³ run along-
side the two longitudinal sides of the apparatus, then come the channels **
ff&c., the central and axial channel n of the apparatus is reached. These
channels formed by the longitudinal bars c are so arranged as to be alternately
connected together at the upper and lower ends of the casing a. As the two outer-
most channels f f communicate through the openings g g with the small
division a¹ of the casing a, the liquid in this division enters these channels
and run along the saine as far as their end when it is diverted into the channels
in order to run back towards the foremost cross bar b, being now again deviated in
such a manner as to continue to run along the channels fff &c. until it reaches
the central channel fn. This axial channel fn communicates through an opening h
formed in the cross bar with the small reservoir a'. This cross bar bis surmounted
in the reservoir a' by a transverse slide in such a manner that the latter opens the
inlets g g while the opening h remains closed. The opening and closing. of the
openings gg and can be effected in a reverse sense, or they could be both hold
open while their diameter is more or less reduced.

A feedor, which is not shown in the drawings, supplies the small reservoir u
through the piper while another pipes is connected to the central channel ƒn in
order to remove the cooled liquid.
The casing is tightly pressed by a removable cover k and with the aid of the
screw rods upon the edges of the transverse and longitudinal bars and upon the
tight elastic joint of its frame.
The glazed opening or peep hole n allows the attendant to ascertain by the
turbidity extant that the apparatus requires cleaning. The opening is formed in

for the rod of the transverse slide above
the cover over the middle of the channel
is arranged the stuffing box
mentioned.
When in use the apparatus is covered with ice so as to cool the internal space
of the casing a.
The liquid can be introduced through the channel directly or first through
the outer channels f₁₁ so as to follow a zigzag course on its way to the
channel ƒ », or by a suitable manipulation of the transverse slide i it may be
made to enter partly through the central channel n and partly through the
outer channels this last portion being eventually conveyed to the central
channel after having followed its zigzag course. In each case the liquid is finally
conveyed into the channel ƒ in order to be remove through the pipes.
In the first caso the least amount of cooling occurs, in the second the most intense
cooling takes place and in the third the cooling can be controlled by means of the
slide so as to fulfill all requirements.
Another advantage of this apparatus is that all its internal parts which come
into contact with the liquid required to be cooled are readily, nccessible, and can be
easily and promptly cleaned.
On practical grounds it may be sometimes desirable to place the apparatus close
to the place where the cooled liquid is required. In such cases the apparatus can
be reduced to the size rendered necessary by the surrounding circunstances without
affecting the efficiency and technical action of the same. For this purpose the
accompanying drawings show in Figs. 4 to 10 inclusively various forms of the
apparatus as well as various details.
Fig. 4 shows the cooling apparatus with the cover removed; it has a circular
form and spiral channels.
Fig. 5. shows with the cover removed an apparatus having a rectangular shape
and provided with parallel inner channels.
Fig. 6, is the outside view of an ice box surrounding the apparatus.
Fig. 7. is a transverse section through the centre of this ice box showing the
cooling apparatus and the inlet and outlet cocks and regulating devices; Figs. 8
to 10 showing the principal positions of this regulating cock.
In these small size apparatuses, the principle remains the same as described
with reference to Figs. 1 to 3, but the details of construction are greatly
improved.
The cooling apparatus a is arranged in the centre of an ice box / provided with
a cover and closed on all sides as shown in Fig. 7. This cooler may have the form
shown either in Fig. 4. or in Fig. 5. or any other suitable shape, of the innor
chaunels b having a corresponding form and being rendered readily accessible by
reason of the apparatus a consisting of two sections in such a manner that two
circular (Fig. 4) or two rectangular sections Fig. 5. tightly screwed together form
a cooling apparatus.
The cross section of the channels is semi-circular and the upper part or cover
of the cooling apparatus a marked c in Fig. 7. The glazed peep hole & shown in
Fig. 4 fulfills the same purpose as n in the above described arrangement. Instead
of the transverse slide the regulating two ways cocks shown in Figs. 4, 8, 9
and 10 is used and receives from the pipe 2 Fig. 7 the liquid conveyed from the
cellar or storehouse.
When the regulating cock communicates by one opening only with the channel w
as shown in Fig. 10 the liquid runs the shortest way through the cooling apparatus a
when it communicates similarly with the channel C Fig. 9. the liquid runs the
longest way through the cooling apparatus a, but when it commanicates by its two
openings with the two channels w and C the liquid follows partly the shortest and
partly the longest way the two streams becoming mixed before running out of
the tap s.
The liquid is thus compelled to travel in a zigzag direction when the apparatus
of Fig. 5 is used or in a spiral direction when the apparatus shown in Fig. 4 is

page_text: utilized. The flow of liquid is exactly the same here as in the description of
Figs. 1 to 3, and the result and purpose in view do not vary. Upon the regulating
cock which carries a quadrangular stem is placed a key provided with a knob
extending out of the ice box fand capable of being adjusted along a divided
circular arc or limb carrying the words Cold and Warm. These two extreme and the
central position correspond to those of the cock in Figs. 8 to 10 respectively.
The effect obtained by the zig-zag or by the spiral form of the channels may be
also obtained by the mere use of ribs thus enabling me to devise a cooling
apparatus of the simplest possible construction producing a like result.
In the accompanying drawings, which illustrate the construction of this
apparatus,
Fig. 11 is a plan view of a cooling apparatus with the cover removed.
Fig. 12 shows the same apparatus partly in cross section and partly in elevation.
The construction of the apparatus is carried out in the same manner as shown
in Figs. 6 and 7.
It consists likewise of two sections a and b tightly scrowed together by the
thumb screws c. The liquid requiring to to be cooled enters at d and exists
through the outlet opening e. The communication between the inlet and the outlet
openings and e respectively is shortest through the channel and lougest through
the channel and it is subsequently carried on through the free space formed
between the ribs g g Fig. 12. The liquid may however follow according to the
portion of the regulating cock either the shortest or the longest way in the same
manner as in the preceding case. For instance, in the position of the regulating
cock shown in Fig. 11, the liquid leaves the ontlet opening e having the same heat
as the cellar; the remaining positions will not require, after what has been said
above any further description, the arrows clearly showing the direction in which
the liquid flows.
The ribs y have a lesser height near the periphery of the circular cooling
apparatus than in the centre and hence the speed of the flow decreases from such
periphery to the inner points of the ribs, so that the liquid remains a shorter or a
longer time in contact with the ice. By altering the height of the ribs in con-
nection with the short channel the flow between g g can be altered as well as
the temperature. The peep hole t serves the same purpose as d in Fig. 4 and n in
Fig. 1 and as regards cleaning this apparatus is' quite as perfect as those above
described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A cooling apparatus for beer and other liquids consisting of a cooler covered or
surrounded by ice and characterized by two or more sections firmly pressed upon
one another and of different external shape provided with a number of chambers
likewise of different shape so as to cause the liquid required to be cooled to follow
either a zigzag or a spiral course, this liquid being compelled by suitable means
to follow a short or a long course or partly a short and partly a long course for the
purpose of being able to draw off such liquid either at a low or at a menu or at
a high temperature, substantially as herein described and shown.
