Improvements in Beer Delivery Apparatus.
I EMANUEL DUDA, Engineer, of 16 Kuchgarten, Harburg a/ Elbe, in the
Empire of Germany, 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 present invention relates to the adjustable cooling of beer, effected by
causing the beer when drawn to pass partly or entirely through a cooling apparatus,
or to pass out without the intermediation thereof as desired."
The cooling apparatus employed for this purpose is shown in duplicate
arrangement, on the annexed drawing, attached to the case S.
Figure 1 shows the front view of the left half of this case whilst the right half
shows a vertical section of the cooling apparatus K. on the line A-B.
Figure 2 shows a vertical section through the case on the line CD with the
cooling apparatus lying to the right in side view, whilst
Figure 3 shows a top view thereof with part of the top cover removed.
Figures 4 and 5 give sections on an enlarged scale of a five way cock F forming
part of the cooling apparatus.
This cock is connected to the beer pipe and is so constructed that the upright
supply pipe entering at 0 may be brought as required into communication with
either of the outlets I-IV.
The cooling apparatus consists essentially of a number of tubes surrounded by
ice or cold air and arranged between two ends D D', of which two always
communicate at adjoining ends and so enable the beer to be cooled to traverse in
alternating directions the horizontal rows of pipes. Furthermore the two left
hand superposed pipes of the first and second rows are in communication and also
the two superposed pipes of the second and third rows at the right of the apparatus.
An alteration in the cooling of the beer takes place by an alteration in the
length traversed by the beer before its arrival at the draw tap =. If by suitable
adjustment of the cock k, which is operated from outside by the handle h, the
supply pipes is put into communication with pipe I of the apparatus, the beer.
traverses the six pipes on the same level in order to flow out through pipe V to the
draw tap. If the supply pipe s is connected to pipes II or III the beer is compelled
to pass through the intermediate twelve or eighteen pipes in order to finally pass
out as before through pipe V to the point where it is drawn. If however it is not
desired to pass the beer through the cooling apparatus the supply pipes is connected
to the pipe IV leading direct to the draw tap. As the two pipes IV and V
communicate at p there is inserted a valve at this point acting in the direction of
the flow. This valve opens upwards when there is pressure in the pipe V and is
closed downwards with pressure in the pipe IV. The position at any time of the
five-way cock is shown on the outside of the case by suitable marks, as for instance,
the numbers I II III and IV on which a pointer t is set.
As the apparatus is surrounded by pieces of ice a greater or lesser cooling of
the beer takes place corresponding to the proportion of the apparatus through
which the beer flows. In order to prevent the beer going flat or being spoiled in
the pipes not in use, a small groove n is made in the circumference of the cock k
or small holes 6 are bored by means of which a slight current flows through the
pipes not in use.

page_text: 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 1
claim is
1. A beer delivery apparatus in which a variable cooling of the beer is obtained
by the distance traversed through sets of pipes surrounded by ice or cold air being
adjustable, according to the degree of coldness desired, by a suitable movement of
a cock fitted to the supply pipe to the cooling apparatus substantially as described.
2. In the apparatus mentioned under Claim 1: The several way cock F
connected on the one hand to the cooling apparatus and on the other directly to
the draw tap and the rotating part of which, besides the principal way, is also
provided with a groove n to connect the separate pipe openings together, or with
small holes for the purpose of maintaining a small stream of the liquid in the
pipes which may at any time be cut out of the circuit substantially as described.
