Improvements in or relating to Vessels for Containing Foaming or
Effervescent Liquids.
I, JOACHIM FRIEDLÄNDER of Nicolaistadtgraben 16, Breslau, in the Empire of
Germany, Merchant, 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 object of the present invention is to produce a vessel for containing foaming
or effervescing liquids or liquids impregnated with gas such as, for instance, beer,
which vessel has the advantage, that the liquid can be drawn off or sent out
in greater quantities, than is possible in bottles, without losing its carbonic acid,
when drawn off, that is to say, without becoming "flat," and even when a
part of it has been drawn off, the remainder can be kept for a long time, without
getting spoiled.
In the accompanying drawings,
Fig. 1 is a vertical central section and
Fig. 2 a corresponding side elevation of an improved vessel constructed according
to this invention.
a is the vessel proper or main vessel and a second vessel, which is used
The
as a cover and can be connected with the first one in an airtight manner.
vessel is used as a receiver for compressed gaseous carbonic acid, which is
introduced into the vessel a by means of a pressure-reducing valve c, merely
indicated diagrammatically in the drawing. The pressure-reducing valve cis
placed in a cavity, which is separated from the interior of the vessel band which is
open at the top and closed by a screwed plate d. The carbonic acid enters from
the vessel b through an opening e into the valve c, and from there passes through a
pipe into the vessel a, where it exerts a pressure on the liquid. The liquid
is drawn off to the last drop, according to necessity through a draw-off cock g,
which is fixed to the vessel b, with a pipe, attached to this cock and reaching to the
bottom of the vessel a, while such an amount of carbonic acid passes from time
to time, from the vessel binto the vessel a, as will maintain the necessary pressure
in the latter.
The use in the vessel b of gaseous carbonic acid has the advantage, as compared
to the use of liquid carbonic acid, that there can never be a very strong pressure,
bringing about the destruction of the vessel a in case the reducing valve does not work
properly; because the small amount of gaseous carbonic acid in 6 is only sufficient
to maintain in a a small excess of pressure over the atmospheric pressure and to
expel all the liquid from the vessel.
The connection of the vessels a and b is best effected so that at the upper edge of
the vessel a there is a flange i and round the neck under that collar there is
a ring with lugs, having holes with screw thread cut in them. Opposite these
lugs there are similar lugs on the vessel b, so that an airtight joint between the
vessels a and b can be made by inserting suitable packing and between them and
connecting them by screws m. In order to secure the handle n, there is round the
middle of the body of the vessel a another ring o and the handle is fixed to it and
to the ring k by means of suitable screws or pins ko¹.
A branch pipe g, provided with a check-valve and with a screw-cap p is used to
fill the vesselh

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is;-
1. A vessel for containing effervescent liquids and the like characterised by
a main vessel (a) for the liquid and a secondary vessel (b) connected to the main
vessel in an airtight manner and forming a cover, containing compressed gaseous
carbonic acid, and having a reducing valve (c) for introducing carbonic acid into
the main vessel a and a draw-off cock (g) with a syphon pipe (h) reaching to the
bottom of the main vessel a substantially as described.
2. A vessel for drawing-off containing effervescent liquids and the like
characterised by a reducing valve placed in a depression of the upper wall
of the carbonic acid-receiver, which depression can be closed by a lid d substantially
as described.
3. The improved vessel for containing effervescent liquids and the like as and for
the purpose described and illustrated in the accompanying drawings.
Dated this 10th day of February 1896.
