Improvements IN Cooling Beer,
I, DIEDRICH STRIEBECK, of Dieringhausen, Station Tavern, Rhenish Prussia,
Germany, Innkeeper, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a new process and means used therein for cooling liquids
such as beer and the like either for direct use or for storing the same in a cold
state. In carrying out my process I proceed as follows:
The barrel on tap is connected as usual to a pressure pump or other suitable
means forcing the beer out of the barrel; a pipe leading from the bottom of the
barrel conducts the beer to a refrigerator where it receives its first cooling, from
this refrigerator the beer is then carried into a barrel full of beer, entering therein
at the highest place of this barrel and being mixed with the same and cooling it,
the cold beer sinking thereby to the bottom by law of nature, but at the same
time by the over pressure caused in the second barrel by the cooled beer entering
therein the contents are forced out of this barrel a tapping tube being provided
for this purpose which is stuck into the barrel right down to the bottom of the
same, where the tube is open so that the beer will be forced upwards in the tube
and made to pass a second refrigerator from which it is then led to the tapping
room ready for consumption. Instead of being led to the tapping room the cooled
beer may be refilled in a barrel for storage in the cold state so that it may be
tapped a certain time later.
When cooling the beer for this purpose, in advance, I use instead of ice as
cooling means one or other of the chemical cooling mixtures such as chloride of
calcium, in order to cool the beer down to a very low temperature, so that it can
be kept cool for several days. This may be of great service for brewers who
supply the beer in barrels to small innkeepers and to families where no ice cooling
means are to be had.
The apparatus used in carrying out my process consists of a tank or receptacle,
preferably with glass sides, containing the cooling fluid or other cooling medium
and also the refrigerator proper, which may consist of a double coil of pipes placed
in said cooling medium or of two cooling colums composed of several vertical
pipes each with a top and bottom piece causing the beer to flow up and down
in a zigzag course in said colums suitable connecting and fitting pieces being
provided, so that the course taken by the beer can be changed, entering first one
column or one coil, going then through the second barrel and passing then through
the second column and being thence led away to the tap room or to the storing
barrel or vice versa or that both colums or coils may be connected, so that the
beer can pass through them in one current without being carried through an
intermediate barrel between them.

I, DIEDRICH STRIEBECK, of Dieringhausen, Station Tavern, Rhenish Prussia,
Germany, Innkeeper, 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:.
-
My invention relates to a new process and means used therein for cooling liquids
such as beer and the like either for direct use or for storing the same in a cold
state. In carrying out my process I proceed as follows:
The barrel on tap is connected as usual to a pressure pump or other suitable
means forcing the beer out of the barrel; a pipe leading from the bottom of the
barrel conducts the beer to a refrigerator where it receives its first cooling, from
this refrigerator the beer is then carried into a barrel full of beer, entering therein
at the highest place of this barrel and being mixed with the same and cooling it,
the cold beer sinking thereby to the bottom by law of nature, but at the same
time by the over pressure caused in the second barrel by the cooled beer entering
therein the contents are forced out of this barrel a tapping tube being provided
for this purpose which is stuck into the barrel right down to the bottom of the
same, where the tube is open, so that the beer will be forced upwards in the tube
and made to pass a second refrigerator, from which it is then led to the tapping
room ready for consumption. Instead of being led to the tapping room the cooled
beer may be refilled in a barrel for storage in the cold state so that it may be
tapped a certain time later.
When cooling the beer for this purpose, in advance, I use instead of ice as
cooling means one or other of the chemical cooling mixtures such as chloride of
calcium, in order to cool the beer down to a very low temperature, so that it can
be kept cool for several days. This may be of great service for brewers who
supply the beer in barrels to small innkeepers and to families where no ice cooling
means are to be had.
The apparatus used in carrying out my process consists of a tank or receptacle,
preferably with glass sides, containing the cooling fluid or other cooling medium
and also the refrigerator proper, which may consist of a double coil pipes placed
in said cooling medium or of two cooling columns composed of several vertical
pipes each with a tap and bottom piece causing the beer to flow up and down
in a zigzag course in said columns: suitable connecting and fitting pieces being
provided, so that the course taken by the beer can be changed, entering first one
column or one coil, going then through the second barrel and passing then through
the second column and being thence led away to the tap room or to the storing
barrel or vice versa or that both columns or coils may be connected, so that the
beer can pass through them in one current without being carried through an
intermediate barrel between them.
The mode of proceeding will be best understood by means of the following
description in connection with the drawing annexed hereto, in which:
Figure 1 shows the arrangement used when cooling for immediate use;
Figure 2 shows the same when the beer is to be cooled for storage;
Figure 3 is a detail view of a special filling cock used for this purpose.
In carrying out my invention I proceed as follows: The barrel A. the contents
of which are to be emptied and cooled to a fit temperature for consumption is
connected by means of a so called syphon cock B of known construction by one
branch C to a pressure pump or flask containing carbonic acid under pressure, and
by the branch D and pipe E to a refrigerator F. This consists by preference of

page_text: a series of pipes leading the beer in a serpentine repeatedly up and down, the
whole being placed in a receptacle G containing a cooling medium, cold water, ice
or a chemical cooling mixture, such as chloride of calcium and others; by the
pipe H the now already cooled beer leaves the cooler F and is led into a barrel K;
by a similar cock B as the one before mentioned B; the branch C in this case
being connected to the pipe H instead to a pressure pump and by the branch D
a pipe is connected to the barrel, the open end of this pipe E, like that of
the pipe E, reaching down to the bottom of the barrel. From this arrangement
it will be understood that the cold beer flowing from H into the barrel K here
mixes with the beer contained therein and cools it, the cold fluid sinking by law
of nature down to the bottom, and it is driven out through the pipe El by the
overpressure caused by the entering beer driven out of the barrel A
At the top
the pipe E is connected to a second refrigerator F in the tank G where it is cooled
down still more and finally leaves it by the pipe L, whence it is guided to the
bar or to an other place of consumption, or as the case may be, to a place of
storage. When the barrel A has been emptied a new one is put in its place and I
can continue to proceed in the same manner as before. Instead of this however
I prefer now, so to say the reverse course. I connect the branch C' of the cock B
of the second barrel by a pipe C2, indicated in dotted lines to an air pressure pump
or its equivalent and I force the cooled contents of the barrel K now up through
the pipe E and the refrigerator F, but instead of conducting it by the pipe L to
the tap room, I now lead it by this pipe or rather by the pipe L', as indicated in
dotted lines, down into the barrel, which was put in place of the emptied barrel A.
in this case connecting the pipe L' to the branch C. As in the first case, the
overpressure now caused in this barrel A forces the beer out of this through the
pipe E into the refrigerator F to which, instead of the downpipe H, an outlet
pipe H, indicated in dotted lines, is now connected and by this pipe H' the
cooled beer is led to the tap room or other place of consumption. When the
barrel K, has been emptied a fresh one is placed in its place and now the pipe
connections are again reversed and put in working order as they were in the first
instance and the beer from the barrel A is now again driven through E, F, H, K,
E, F to its place of destination and so on in continuous alternation.
From the foregoing description of my method of cooling beer or other liquids
it will be understood that the essential of it consists in this, that two sorts of
beer of different temperatures are mixed with each other by driving the contents of
a new barrel through a refrigerator and thence (when the process is once in
regular order) through the barrel containing beer that had been cooled before,
where the beer is mixed and driving then the contents of this second barrel out
of it by the overpressure caused by the new beer entering therein and leading
it from the bottom of this barrel up to a second cooler whence it finally is
conducted to its place of destination.
As above mentioned, my method may be used for cooling beer for immediate
consumption as well as for storage in a cold state.
The proceeding in this case is the same as before and the apparatus used
therein is also the same, with that slight difference that the outlet-pipe instead
of leading to a tap room now conducts the beer into a storage barrel by means
of a cock specially constructed for this purpose, so that the storage barrel, when
filled, can be hermetically closed and no air can come in contact with the beer
though the filling pipe is withdrawn.
I will shortly explain this manner of my process by means of the arrangement
shown in Figure 2.
The barrel a, full of beer, is provided with the cock b; its branch c is connected
to an air pressure pump by means of which the beer is forced out of the barrel up
through the pipe é attached to the branch d of cock b; by pipe e the beer is led
into and through the cooler f in tank and then by means of a pipe h it is
conducted into the barrel K by a similar cock 61 as in the preceding case and

page_text: it is then forced up through pipe e¹ into the cooler f¹ and from this cooler it is led
away by pipe and a specially constructed cock m into the barrel n for storage.
Now in order to prevent communication of the beer in the storage barrel with
the air in such a measure, that the quality of the beer might suffer, by escape of
carbonic acid for instance, and thus get stale, I provide the barrel with a specially
constructed cock m for introducing the pipe 7.
Figure 3 shows this cock in a longitudinal section; it resembles in the whole
to the ordinary syphon cock" like the cocks B and B', but with that difference
that between the upper stuffing box and the branch o (corresponding to the
branches C and C¹ in Fig. 1), there is inserted a tap with a hole wide enough
in its cone that the tube e can be passed through conveniently. This cock
for its object to close the barrel hermetically when it is filled and the tube /
has been withdrawn so that no new bunging of the barrel is necessary and that
it be ready for being connected to an air pressure pump and an emptying tube
as usual at a moments notice.
has
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:
1) In cooling beer the process of driving the contents of a barrel through a
cooler into a second barrel full of beer of the same sort, thereby mixing the
already somewhat cooled liquor from the first barrel with that in the second barrel
and forcing the mixture out of the second barrel from its bottom up through a
second cooler and thence by a suitable pipe either to a tap for immediate use or
into a third barrel for storage in a cold state as described.
2) Apparatus used in carrying out the new process of cooling beer as described
in Claim One consisting in the combination of a cock B having branches C and D,
the one for connecting it to a pressure medium, the other for connecting it to an
outlet pipe E, with a cooler F connected to said pipe E, a pipe H conducting the
beer from cooler F into a second barrel K, a cock B allowing the connection of
barrel K to a pipe E¹ and a second cooler FI provided with an outletpipe L,
the whole as set forth and for the purpose specified.
3) With an apparatus for carrying out the new process for cooling beer specified
in Claim One and consisting of a cock b, a pipe e, a cooler f, a pipe h, a cock b¹.
a pipe el, a cooler f¹ and a pipe 7 the combination of a cock m having a special
cone between the stuffing box n and the branch and allowing to close the
outlet passage after the withdrawal of the pipe 7, the whole as described and
illustrated and for the purpose set forth.
