Improved Portable Liquid Receptacle with Compressed Gas
Receiver.
I, JACOB LOEBINGER, of No. 61 Kommandanten Strasse Berlin, Empire of
Germany, Merchant, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly ascertained in and by the
following statement :-
The present invention consists of a portable liquid receptacle having compressed
gas receiver in connection therewith and means for allowing the gas to communicate
with the liquid when the same is drawn off in the known manner. By ordinary
vessels of this kind the construction of the cock is generally such that as soon as the
tap is opened to draw off a glass of the liquor, the gas is placed in connection or
communication with the liquid with the full force of its pressure and the consequence is
that the liquid is blown into the glass with a large amount of froth and difficulty is
experienced in properly filling the glass. The present invention comprises means for
gradually letting the pressure of the gas on to the liquid and not allowing the full
force of the same to escape from the gas reservoir into the liquid receptacle until the
liquid channel of the plug of the cock has been fully opened.
And in order to render the present specification more easily intelligible, reference
is had to the accompanying drawing, in which similar letters of reference denote
similar parts throughout the several views ;-
Fig. 1 is a side elevation of the receptacle with cock,
Fig. 2 a central vertical section through the same, taken through a centre line at
right angles to the view of Figure 1,
Fig. 3 is a detail cross section through the plug showing the cock closed and
Fig. 3 a similar section with the plug open.
The receptacle a for the liquor is provided with a cover c secured by screws in the
usual manner and having a tightening ring or washer d. To the cover and inside the
same is advantageously attached the gas receiver f, having a check valve h with
upwardly extending stem 4'. The said cover is provided with an upward extension d'
forming the casing for the plug b, which is hexagonal at one end for the reception of
the handle g and a cam g', adapted to operate the valve stem ¹, as hereinafter
more particularly described. Both these parts are secured in position by a nut b¹. In
the cover ca channel i is formed leading from the valve h to one end of the cock plug,
a second channel leads from the other end of the plug to the interior of the
receptacle a. The plug itself is provided with a longitudinal boring leading into
the tube a radial boring k corresponding to the boring in the housing c¹ which
leads to the tube m for the exit of the liquid and a groove o along the surface of
the plug, having a cross section deepest at the centre and being made shallow
towards the sides, said groove being adapted when the plug is in position to
connect the two channels and i¹.
The device operates in the following manner :-
When the handle of the plug is turned to allow the liquid to flow out at 6³, the
cam g' gradually lowers the valve by pressing on its stein h¹, at the same time as the
channel k begins to communicate with the channel, connecting with the exit pipe m,
the tapered or shallow part of the groove o just begins to communicate with the
channels i, and the back pressure valve h is being slightly raised from its seat. Thus
the passage of the gas-such as carbonic acid, at the beginning of the opening of the
B

page_text: cock will be very limited, whilst the further the cock is opened, the greater will the
passage from i to i¹ along the groove a become, and at the same time the valve / will
be further depressed by the cam g'. Thus, as soon as the cock is wide open, all the
channels will be in full communication with their respective outlets.
The gas receiver f need not necessarily be arranged within the receptacle a, as the
same could be placed on the cover or in any other convenient position as long as
it communicated in the manner described with the interior of the receptacle. The
back pressure valve h could also be arranged at the juncture of the channel ¹ with the
interior of the receptacle instead of at the channel i, without departing from the
nature of the invention.
A valve p is provided on the cover to let off the superfluous pressure from the
interior of the apparatus. A pipe f' leading by a channel to the interior of the gas
receiver, may be employed to fill the receiver with gas.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
-claim is ;-
1. The combination of a liquid receptacle and a gas receptacle, a cover to the
former having a cock plug mounted therein, channels from the interior of the gas
receptacle to the cock plug, from the opposite end of the said plug to the interior of
the liquid receptacle, and a channel from the lower part of the receptacle to the plug
-outlet, a shallow groove along said plug to connect the channels from the gas
receptacle to the liquid receptacle, a back pressure valve to control said gas channels
and means in connection with the plug stem to gradually open said valve, when the
cock is opened, substantially as described.
2. The combination of a liquid receptacle a having cover c and gas reservoir
mounted thereunder within the receptacle, a plug mounted in said cover and channels
in said cover from the interior of the gas receiver to the plug and from the plug to the
interior of the liquid receptacle, a shallow channel on the mantle of the plug to
connect the channels from the gas receiver to the receptacle gradually when the cock
is opened, a channel from the lower part of the receptacle through the cock to the
receptacle outlet, a back pressure valve to govern the gas channels and a cam g¹ on
the cock plug to operate said valve and gradually open the same when the plug is
turned substantially as described.
