Apparatus for Supplying Carbonic Acid Gas to Liquors in Casks or
other Receptacles.
I, HENRY HURTER of Coblenz, in the Empire of Germany, Wine Merchant, do
hereby declare the nature of the 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 object of this invention is to provide means for supplying carbonic acid gas to
casks or other receptacles containing liquors such as Water, Beer, Wine, Lemonade
or any other liquid to which carbonic acid gas may be desired to be supplied either
for so providing pressure thereon for convenient drawing of the liquor from the
receptacle, or for aerating the same.
To this end the invention consists in providing for each cask or like receptacle,
preferably within the cask, a reservoir in which carbonic acid under pressure has been
stored, in connection with a valve adapted to be opened by a key so that the carbonic
acid gas may be allowed to escape as and when desired from the reservoir into or
within the cask until the former is exhausted.
The accompanying drawing illustrates a suitable reservoir and valve adapted to be
fixed within a cask. Fig. 1 is a longitudinal section of the device closed, Fig. 2 a
similar view of the same open. Fig. 3 shows a suitable key for operating it.
A is the reservoir, B the valve. The reservoir is preferably a cylinder of wrought
iron closed at one end and provided with an opening at the other end in which the
valve B is screwed. C is a narrow passage communicating with the reservoir A
through a perforated guard D, this passage opening above into the chamber E in
which the spindle F is screwed and which is provided with the lateral outlet G. The
lower end of the spindle F is recessed to receive a leather or like facing H to securely
close the passage Ċ when the spindle is screwed down. The spindle is screw threaded
to engage in a female screw thread fixed in the upper part of the walls of the
chamber E and above this screw threaded portion is turned true to pass through the
stuffing box J which compresses the thimble K adapted to be adjusted by the nut I,
the rubber ring L and the collar M. The uut I is so adjusted that when the
spindle F is screwed up and the passage opened, the collar M on the spindle will
compress the rubber ring L and so prevent any escape of gas around the spindle F.
The latter terminates in the triangular or equivalent head N to be turned by the key.
To protect the head from being unscrewed in transit, and to provide means for fixing
the apparatus in cask, the nut I carries the cylindrical wall which is screw threaded
to receive the removable cap T. On the end of the cylinder A is an equivalent screw
threaded block R to receive the cap T when not in use.
The outlet of the passage G
is covered by a cap nut in transit. Greater capacity of the apparatus is preferably
attained by use of longer cylinders A.
Having filled the cylinder A through the passage G by means of any usual
apparatus for manufacturing or filling carbonic acid, the spindle F is screwed down
and the cap T and the nut over the passage Gare screwed in place. The apparatus
may thus be kept filled for an indefinite time. To insert the apparatus in a barrel or
the like, a double screw plug or bung is provided in the latter, that is to say a
removable screw plug, having in itself an opening likewise closed by a removable
plug. This double plug is unscrewed, the apparatus is screwed in the place of its
inner plug so that the head may be reached through the opening in the plug, the
apparatus is passed into the cask and the outer or main screw plug, now carrying
the apparatus is screwed in its place. By turning the spindle E the carbonic acid
gas will escape within the cask. In place of screwing the part 0 into the plug, the

page_text: part R could be screwed therein, but in such case the valve A would have to be
opened before screwing back the plug.
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 with a cask or other receptacle of an apparatus comprising a
reservoir for carbonic acid and a valve thereto, adapted to be fastened within said
cask whereby carbonic acid gas may be allowed to escape therein substantially as and
for the purpose set forth.
2. The construction of the reservoir A and valve B substantially as herein described
and illustrated for the purpose set forth.
