page_text: I ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Engineer 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 cooling of the beerwort from 50° or 70° to 2 or 1° is one of the principal features
of brewing and for this purpose various apparatus are used which however either
fulfill their purpose unsatisfactorily or with too great a waste of the cooling material.
With the apparatus or refrigerator represented in the accompanying drawings
Fig. 1-7 the greatest cooling power is obtained because of the peculiar construction
in which all waste of space is avoided.
The apparatus consists of a series of channels a of triangular section which are
arranged in two rows over each other in such a manner that they correspond with
each other, the whole is divided in two by the cylindrical channel a¹ to allow the use
of two different cooling fluids i.e. ice water and spring water. b is the channel from
which the beerwort is distributed over the cooling surface through the holes c.
The collecting channel d is constructed with three bottoms for the further cooling
of the beer and is connected with the channel system by the pipe e. The channels a
are in communication with each other through the sides with the intervening plates g.
The sides are closed by plates h and screws and nuts. The whole apparatus is carried
by the feet k.
The ice water enters through the middle compartment of the collecting channel d
and passes
to the channel system through the pipe e and leaves the apparatus after
passing through the channel a¹. The upper part is supplied with well water, which
enters through a³ and leaves at a¹, the water thus passes through the channels from
bottom to top. The beerwort collected in the channel d passes into its lower compart-
ment through the passage m and thence to the cellar through the pipe u.
collecting channel even is thus used for cooling the beer.
The

page_text: The apparatus represented in Fig. 4 to 6 is only different from the above described
in so far that in arranging the channels a in a greater number next to each other a
greater cooling surface is obtained to use the cooling fluid to the utmost possible
extent. In this arrangement the side pieces are omitted and the cooling fluid
flows direct from one channel to the other as represented by the arrows in Fig. 5.
The collecting channel is here not provided with several compartments and the channels a
are closed on the sides by plates h as described before.
Fig. 4 is a side view of this arrangement without the plate h to shew the arrange-
ment of the channels a here shown at 4 next to each other as at A-B. Fig. 5 is
a section on line A-B of Fig. 4. Fig. 6 is a front view, part section, of the apparatus.
In this arrangement also two cooling fluids are used. The icewater enters the
apparatus direct at a without passing first through the collecting channel d, and leaves
at a. The wellwater enters at a³ and leaves at a. The beerwort passes from the dis-
tributing channel b over the cooling surfaces to the collecting channel d.
In Fig. 7 three channels a arranged side by side to show that any desired number
of channels may be used according to the work the apparatus has to perform.
Having now particularly described and ascertained the nature of the said invention
as communicated to me by my foreign correspondent and in what manner the same is
to be performed I declare that what I claim is :-
1. In an apparatus for cooling beer the alternate arrangement of the triangular
cooling channels merely touching each other at their edges substantially as specified.
2. In an apparatus for cooling beer the alternate arrangement of a number of
triangular cooling channels side by side only touching at their edges and thus forming
a continuous inclined cooling surface substantially as specified.
