COMPLETE SPECIFICATION.
Improved Combined Carbonic Acid Receiver and Pressure Regulating
Mechanism for use in Retailing Liquors.
I, ALBERT MULLER, of 34, Friedenstrasse, Berlin, in the Empire of Germany,
Engineer, do hereby declare the nature of my said 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 consists of a combined carbonic acid receiver and
pressure regulating valve for use in retailing liquors, such as beer and the like.
The invention consists in the details of construction hereafter set forth and
particularly pointed out in the claims:-
-
of
And in order to render the present Specification more easily intelligible,
reference is had to the accompanying drawings in which similar letters
reference denote similar parts throughout the several views :—
Fig. 1 is a central vertical section through the device,
Fig. 2 a plan of the same,
Fig. 3 a horizontal section on line A-B of Fig. 1,
Fig. 4 a similar section on line C-D of Fig. 1,
Fig. 5 section on line E-F of Fig. 1,
Fig. 6 section on line G-H of Fig. 1 and
Fig. 7 side elevation partly in section of a modified form of the device.
Referring to Figures 1 to 6:-The device consists of a bell or receiver which
upper, or carbonic acid
is divided by means of a horizontal partition into an
containing receiver A and a lower chamber B which contains the pressure
regulating mechanism. The partition separating the chambers is provided with
a strengthening rib y, in which is mounted the tubular downward extension e,
forming a channel through which the carbonic acid may pass to the lower
chamber B. The lower end of the tube e is covered or loosely enclosed in an
inverted thimblepiece 9 having therein a plate h adapted to close against the
lower open end of the said tube. This thimble rests on the free end of a lever i
pivoted in a bifurcated bearing piece f screw-threaded into the strengthened party
of the partition. The opposite end of the said lever is pivoted to the lugs n¹
of a nozzle having a boring n², said nozzle being suitably fixed in a membrane k
mounted at the bottom of the chamber B and partitioning this chamber off from
the lower chamber C. The lower chamber C is provided with a tubular down-
wardly extending mouth piece having a lateral opening and bearing interiorily
screw threaded to receive a nut having upwardly and downwardly extending
tubular extensions and being provided with lateral orifices w (Fig. 4) into which
a tool may be inserted through the opening v, so that the position of the said
nut in the throat piece may be varied. The upper surface of the nut forms
the bearing surface for the spring o which bears against a metal washer on the
membrane and has the tendency to push said membrane upwardly. Thus if the
o bears against
position of the nut 2 is altered, the tension with which the spring
the membrane may be regulated. The downwardly extending end of the nozzle

page_text: having boring n² is provided with a flexible tubular extension q consisting of
two parts which are held together by means of an inserted glass tube q', the
lower. end of said flexible tube opening into an upper chamber.formed in the
housing of the cock D. The device is screwed into the bung, plunging-syphon
or tap which is in connection with the cask, its operation will be obvious, as soon
as liquor is drawn off, the pressure underneath the membrane will decrease, and
carbonic acid will pass from the receiver A to the chamber B through the outlet e,
and from chamber B through. the opening n² to the interior of the cask, the
constant pressure in the cask being regulated according to 'the adjustment of
the spring.
The dimensions of the glass and flexible- tubes are 'so chosen that in case of
excessive pressure, the latter will slip off the glass tube and thus form a reliable
safety valve. "The top of the receiver A is provided with a valve device through
which carbonic acid may be supplied to the said receiver. At the upper part of
the housing A is provided a nozzle having interior and exterior threads, into
the former of which a plug r is screwed, whilst the latter is covered by: means. of
a nuta, the lower part of the plug r is hollowed out to receive. a second
plug d having therethrough an orifice t, said plug forming with its upper surface
a seat for a free lying valve plate c, having formed in its under surface channels s, s
(Fig. 6). The main plug is provided with a central vertical channel u and
with two depressions z, z by means of which the said plug may be screwed into
the neck of the receiver. When carbonic acid is to be supplied to the receiver A,
the nut a is unscrewed and the mouth piece of the carbonic acid flask screwed
on to the neck of the receiver. The carbonic will flow through the channels s
into the receiver A and when the flask is detached from the neck or nozzle of the
receiver, the valve plate c will be closed by the interior pressure against the
plug thus preventing the escape of the carbonic acid from the receiver.
In the modification shown at Fig. 7 instead of the orifice n² a laterally formed
channel a¹, a¹ is provided, the device is otherwise the same as that previously
described. The cock D may be employed to close the apparatus when it is shifted
from one cask to the other, or when it is charged and not in use.
Having now particularly described and ascertained the nature of my, said in-
vention and in what manner the same is to be performed, I declare that what I
claim is;-
1: The combination of a carbonic acid receiver, and a membrane chamber, made
in one piece and a partition formed in said receiver between the same and the
membrane chamber, an outlet opening from the receiver to the chamber and means
in connection with the membrane to close and partially close the same, a membrane
mounted at the bottom of said chamber a spring underneath said membrane, an
outlet from said chamber to and through a cock, and means for adjusting said
membrane spring, substantially as described, and means for introducing carbonic
acid into said receiver substantially as described.
2: The combination of a carbonic acid receiver and a membrane chamber in
one piece and a partition wall between the two, a tubular outlet from said
receiver to the chamber and an inverted thimble piece in said chamber to loosely
-enclose said outlet, lever in connection with a membrane to operate said thimble
piece.as specified, a spring underneath said membrane and means for adjusting the
same, an outlet from said chamber to the cask and means for supplying carbonic
acid to said receiver, substantially as described.
3: The combination of a carbonic acid receiver and a chamber as specified, and
partition between the two, a tubular outlet e from the receiver to the chamber,
having inverted thimble piece to enclose same loosely, a lever i and means for
suspending the same pivotally from the partition wall between the receiver. and
chamber, pivotal connection between the end of said lever and a downwardly ex-:
tending nozzle, a membrane closing the bottom of said chamber and means for

page_text: attaching said nozzle to the membrane, a chamber C below said membrane having
throat piece with lateral opening v, an adjustable nut in said throat piece accessible
through said opening, a spring arranged between said nut and a plate on the
membrane, a flexible tube connection from the membrane nozzle said tube
connection being in two parts, a glass tube to connect said flexible tube parts, a
cock to close said throat piece and means for securing the whole to the cask or
the like substantially as described.
4: The combination of a carbonic acid receiver, a valve chamber thereunder
and a partition between the two, a membrane underneath and closing said
chamber, a tubular downwardly extending outlet to said partition and inverted
thimble piece to loosely enclose said outlet, a lever device in connection with the
membrane to operate said thimble, a chamber below the membrane having therein
an adjustable membrane spring, a cock below said spring and an outlet from the
valve chamber to said cock, a carbonic acid inlet to the receiver consisting of a
plug having mounted therein a second plug d, an orifice t in said second plug,
a valve plate thereover having channels, s in its under surface and an orifice above
said valve plate through the plug r and a cap nut a to enclose the whole substan-
tially as described.
