Improved Means for Discharging Under Pressure Beer. and other
Potable Liquids from Vessels Containing the Same.
I, JOHANNES DRECKMANN; of. No. 4, Rothenditmolderstrasse, -Cassel, in the
German Empire, do hereby declare the nature of this invention to be as
follows:-
ر
__
My invention relates to improved means for discharging under pressure from
suitable vessels or receptacles, beer and other potable liquids containing car-
bonic acid.
My improved apparatus comprises a liquid receptacle and a receptacle for-holder
for the compressed gas, which receptacles are either permanently or detachably cou-
nected to each other. The essential feature of the invention consists in that the
liquid receptacle is connected with the compressed gas receptacle by a check-
valve opening into the latter, in such a manner that the compressed gas, such
as carbonic acid, introduced into the receptacle before the introduction of the
beer or other liquid, or the air contained in the receptacle, is displaced by
the entering liquid as the said receptacle is filled, and this gas or air is forced
into the compressed gas holder from which it flows back into the vessel through
a reducing-valve, in proportion as the vessel empties itself.
+
In carrying my said invention into practice, the following arrangement can
be advantageously employed:-
The liquid holder or receptacle, which is made of glass or any other suitable
material, is detachably connected with the compressed gas holder or receptacle,
which is made of metal, by means of toggle-joints mounted on the liquid
receptacle, these toggle-joints engaging with hooks or projections on the com-
pressed gas receptacle and a packing ring being employed to make a tight
joint. The two receptacles can however be connected together by other methods
for example, by means of a screw-socket, or they can be permanently connected
together.
An ascension pipe provided with a cock and extending nearly to the bottom
of the liquid receptacle, is mounted on the compressed gas holder, provided with
a reduction-valve from which a tube leads to the liquid receptacle. The latter
() is connected with the compressed gas holder through a check-valve which opens
into the compressed gas receptacle.
The filling of the vessel is effected by introducing a gas capable of being
used for preserving the liquid, for example, carbonic acid, into the liquid
holder through the cock at a suitable pressure, after which the introduction of
5.the liquid likewise takes place through the cock at such a pressure that the
air or gas contained in the liquid-vessel is displaced and is forced through the
check-valve into the compressed gas holder with corresponding compression. The
compressed or condensed contents of the compressed gas holder can then only
enter into the liquid vessel at a reduced pressure through the reduction-valve,

page_text: in order to force the liquid out of the vessel again on opening the said cock.
The reduction-valve can be of any suitable construction.

Improved Means for Discharging Under Pressure Beer and other
Potable Liquids from Vessels Containing the Same.
I, JOHANNES DRECKMANN, of No. 4, Rothenditmolderstrasse, Cassel, in the
German Empire, 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:-
My invention relates to improved means for discharging under pressure from
suitable vessels or receptacles, beer and other potable liquids containing car-
bonic acid.
My improved apparatus comprises a liquid receptacle and a receptacle or holder
for the compressed gas, which receptacles are either permanently or detachably con-
nected to each other. The essential feature of the invention consists in that the
liquid receptacle is connected with the compressed gas receptacle by a check-
valve opening into the latter, in such a manner that the compressed gas, such
as carbonic acid, introduced into the receptacle before the introduction of the
beer or other liquid, or the air contained in the receptacle, is displaced by
the entering liquid as the said receptacle is filled, and this gas or air is forced
into the compressed gas holder from which it flows back into the vessel through
a reducing-valve, in proportion as the vessel empties itself.
A delivery vessel of this kind is shown in the accompanying drawing in
Figure 1 in vertical section and in Figure 2 in front elevation.
The liquid holder or receptacle A, made of glass or any other suitable material,
is detachably connected with the compressed gas holder or receptacle B, which
is made of metal, by means of the toggle-joints H, Figure 2, mounted on the
liquid holder or receptacle A. These toggle-joints engage with hooks or
projections Jon the compressed gas receptacle B and a packing ring is employed
to make a tight joint. The two receptacles can however be connected together
by other methods, for example, by means of a screw-socket, or they can be
permanently connected together.
An ascension pipe F provided with a cock F and extending nearly to the
bottom of the liquid receptacle is mounted on the compressed gas holder B,
provided with a reduction-valve C from which a tube G leads to the liquid
receptacle. The latter is connected with the compressed gas holder B through
a check-valve E which opens into the compressed gas receptacle.
The filling of the delivery vessel is effected by introducing a gas capable
of being used for preserving the liquid, for example, carbonic acid, into the
liquid holder A through the cock at a suitable pressure, after which the
introduction of the liquid likewise takes place through the cock F at such a
pressure that the air or gas contained in the liquid holder A is displaced and is
forced through the check-valve E into the compressed gas holder B with corre-
sponding compression. The compressed or condensed contents of the compressed
gas holder B can then only enter into the liquid holder A at a reduced pressure,
through the reduction-valve C, in order to force the liquid out of the liquid holder

page_text: again on opening the said cock F. The reduction-valve C can be of any suntable
construction.
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. An improved delivery vessel for beer and other potable liquids containing
carbonic acid, in which the liquid receptacle is connected with the compressed
gas receptacle by a check-valve opening into the latter, through which valve
the gas placed in the liquid receptacle before the introduction of the liquid,
or the air contained in the said liquid receptacle, is forced into the compressed
gas receptacle by the liquid flowing in under pressure, and the compressed or
condensed gas or air then flows back from the compressed gas receptacle through a
reducing-valve into the liquid receptacle in proportion as this latter empties
itself.
2. The improved apparatus constructed substantially as described with reference
to the accompanying drawing and operating as and for the purpose specified.
