COMPLETE SPECIFICATION
Improved Method and Means for Foroing Beer and other Liquids
Out of Closed Receptacles
1, FRIEDRICH JEPPEL, Manufacturer, of Mulheim-on-the-Ruhr, in the German
Empire, 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 has for its object a more complete utilisation of the liquid
carbonic acid used for retailing beei, than is the case with the means hitherto
known For this purpose I use the carbonic acid in the first instance for sucking
and compressing atmospheric au, so as to produce a mixture of atmospheric air and
cai bonic acid, which is then caused to act on the beer.
If bee is 1etailed or raised by causing carbonic acid under pressure to act upon
it, the escape of the carbonic acid uaturally contained in the beer, in consequence
of which the latter would become stale, is prevented, but the power of absorption
of the beer for cai bonic acid gas is so great, that instead of pure carbonic acid, a
mixture of the same with an may be used, without depriving the beer of the
cai bonic acid naturally contained in it. The mechanical work of diawing in the
desired quantity of air, compressing and mixing it, is performed by the energy
stored up in the liquid or compressed carbonic acid, preferably by means of an
injector.
The accompanying drawing is a vertical section of an apparatus adapted to force
beer into a closed receptacle according to my invention Liquid carbonic acid is
contained in a cylinder a from which it escapes in the shape of a high-pressure gas
"The jet of gas
into the jector nozzle c, if the valve & and stopcock are open
dnected towards the receiver /draws atmospheric air through a laterally arranged
supply pipe provided with a stopcock 4, and produces a mixture of an and gas
which then enters the receiver f
The latter is made of sheet metal and aimed with a pressure gauge d and safety
valve e.
The cask or other receptacle containing the liquid to be retailed or
aised is connected with the receivci f, instead of which, it may, however, be
duectly connected with the injector. As soon as the pressure in the receiver 15
Eufhcient, the supply of carbonic acid is stopped by closing the valve b, and the
escape of the gaseous mixture through the air supply tube is prevented by an
automatically closing valve g. The cock serves to close the receiver, while the
carbonic acid cylinder a is being exchanged for another.
Instead of using an injector, operated by carbome acid gas for drawing in the
desued quantity of au, an an pump may be used for mixing air with carbonic acid.
Such an pump may be propelled by a carbonic acid motor, and the waste carbonic
aud gas exhausted from the said motor may be utilized by conducting it into the
pressure reservon /.
Having now particularly described and ascertamed the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim 18-
1 The process for forcing beet and other liquids out of closed receptacles by
the pressure of carbonio acid, which consists in producing a mixture of compressed
of the machanical energy stored up in the latter,

page_text: and causing the said mixture to act on the beer or other liquid, substantially as
described.
2. The combination of a carbonic acid cylinder, with an injector and air-supply
pipe, an intermediate receiver and accessories, substantially as and for the purpose
described.
