page_text: I, RICHARD RÜCKFORTH, of 23, Pommerensdorferstrasse, Stettin, in the German
Empire, Brewery Proprietor, do hereby declare the nature of this invention
to be as follows:-
This invention relates to a vessel, for containing beer or other liquids, wherein
the said liquid is drawn off by means of a syphon under pressure of carbonic
acid gas.
"According to my invention I provide the vessel with a hollow handle for the
reception of the carbonic acid.
In carrying out my invention the vessel, for containing the beer or other
liquid, and which may be of any suitable form, is fitted with a hollow handle
which can be removed in order to enable it to be filled with carbonic acid gas.
The handle contains, besides the reservoir for the carbonic acid, a space or division
for a valve and a chamber sealed from the vessel by means of a stuffing box and
into which the syphon tube from the vessel opens. A plate, which covers both
the valve division and the chamber is provided with a tap or cock which is con-
nected with the interior of the vessel through the chamber and the syphon tube.
The valve space is provided with a three-way cock and with a reaction valve which
can be operated from outside by means of spindles passed through openings in the
plate. Both connect the reservoir in the handle containing the carbonic acid
with the interior of the vessel through a passage in the said handle. A second
passage branches from the first passage the said second passage being in connection
with a three-way cock and a safety valve arranged outside the vessel. The handle
is also provided with a filling opening for the carbonic acid and is secured to the
vessel at both ends preferably by means of screw-nuts.
Before the handle is filled with carbonic acid the three-way cock in the valve
space is so arranged that air can escape through it but after the filling operation
it is rotated to shut off communication with the reservoir containing the carbonic
acid.
The vessel is filled with beer or the like through the cock or tap by connecting
this to the filling tube. The air escapes during the filling operation through the
first passage and the outside three-way cock which is open to allow this. After
the vessel has been filled the three-way cock is so arranged that the safety valve
is brought into communication with the interior of the vessel.
To discharge or draw off liquid from the vessel the three-way cock in the valve
space is opened for a short time to allow a small quantity of carbonic acid gas
to escape through the valve and the first passage into the vessel. The pressure

page_text: of the carbonic acid forces the beer through the syphon tube, the chamber and the
open cock or tap.
In a modified construction of my invention the valve is arranged on the upper
end of the handle and from the said valve a tube passes into a second tube arranged
at the upper end of the vessel. The second tube is provided with a cock or tap
from which the syphon tube passes to the bottom of the vessel.
The valve proper or plug of the valve is in this arrangement connected to a
plate by means of a connecting rod,, which plate is normally, that is to say, when
the valve is' closed, not in contact with a diaphragm controlled by a spring. With
this construction a special cut off valve is unnecessary and the compressed gas can
pass from the handle directly into the vessel when the diaphragm is suitably
operated by means of a screw.
The safety valve is in this case connected to the second tube.
I, RICHARD RUCKFORTH, of 23, Pommerensdorferstrasse, Stettin, in the Ge:man
Empire, Brewery Proprietor, 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:-.
This invention relates to a vessel for containing beer or other liquids wherein
the said liquid is drawn off by means of a syphon under pressure of carbonic
acid gas.
According to my invention I provide the vessel with a hollow handle for the
reception of the carbonic acid.
In the accompanying drawing,-
Figures 1 and 2 are vertical sections of two syphon-vessels made according to
my invention.
Figs. 1 and 2 are views illustrating the valves hereinafter described.
In the arrangement illustrated in Figure 1 the vessel A for containing the beer
or other liquid, .and which may be of any suitable form, is fitted with a hollow
handle b which can be removed in order to enable it to be filled with carbonic
acid gas.
The handle b contains, besides the reservoir for the carbonic acid, a space or
division C for a valve and a chamber F sealed from the vessel A by means of a
stuffing box and into which the syphon tube M from the vessel opens.. A plate d
which covers both, the valve division C and the chamber F is provided with a tap
or cock Z connected with the interior of the vessel through the chamber F and the
syphon tube M The xalve space C is provided with a three-way cock and
with a reaction valve R shewn clearly in Figure 1 which can be operated from
outside by means of spindles passed through openings in the plate d. Both connect
the reservoir in the handle containing the carbonic acid with the interior of the
vessel through a passage i in the said handle. A second passage, branches
from the passage the said second passage being in connection with the three-
way cock L and a safety valve. S. arranged outside the vessel A: The handle is

page_text: also provided with a filling. opening K for the carbonic acid and is secured to the
vessel at both ends at B, B' preferably by means of screw-nuts D, D.
Before the handle 6 is filled with carbonic acid the three-way cock o in the
valve space C is so arranged that air can escape through it but after the filling
operation it is rotated to shut off communication with the reservoir containing
the carbonic acid.
The vessel A is filled with beer or the like through the cock or tap Z by connect-
ing this to the filling tube. The air escapes during the filling operation through
the passage i and the three-way cock L which is open for this purpose. After the
vessel has been filled the three-way cock L is so arranged that the safety valve S
is brought into communication with the interior of the vessel.
The valve R forced against its seat by the pressure of the gas is connected to a
diaphragm by means of a rod. Against the upper side of the diaphragm acts
spring which can be adjusted to any required pressure. If, for instance, the
spring has been adjusted to a pressure of 0'1 atmosphere, the valve will be opened
directly the pressure in the chamber situated below this diaphragm and in the
vessel communicating with this chamber falls below the pressure of the spring.
From the gas reservoir, therefore, a quantity of gas will escape, until this pressure
is obtained, whereupon the spring will be forced back and the valve will be closed.
To discharge or draw off liquid from the vessel the three-way cock o is opened
for a short time to allow a small quantity of carbonic acid gas to escape through
the valve R and the passage i into the vessel A. The pressure of the carbonic
acid forces the beer through the syphon tube M, the chamber F and the open cock
or tap Z.
In the modified construction of my invention shewn in Figures 2 and 2 the
valve R is arranged on the upper end of the handle and from the said valve a
tube 6 passes into a second tube 6 arranged at the upper end of the vessel A.
The tube 6 is provided with a cock or tap Z from which the syphon tube M
passes to the bottom of the vessel.
The valve proper or plug f¹ of the valve R is in this arrangement connected to
a plate f" by means of a connecting rod, which plate is normally, that is to say
when the valve is closed, not in contact with a diaphragm controlled by a spring.
The pressure of the spring acting upon the diaphragm can be decreased or relieved
by raising the upper plate on which the spring bears, by turning the screw R¹
when the valve will be tightly closed by the pressure of the gas. When the
apparatus is to be set in action the pressure of the spring will have to be ad-
justed by moving down the said upper plate by means of the screw R until the
pressure of the spring overcomes the pressure in the vessel. With this construction
a special cut-off valve is unnecessary and the compressed gas can pass from the
handle b directly into the vessel A when the diaphragm is operated by means of
the screw R¹.
The safety valve S is in this case connected to the tube .
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. In a vessel for containing beer or other liquids and having a gas container,
forming the handle (6) hollow and employing it as the holder or container for the
carbonic acid gas, substantially as described and illustrated.
2. A vessel of the kind described in Claim 1 in which the hollow handle (b)
is also provided with means for drawing off liquid, substantially as described and
illustrated.
3. A vessel of the kind described in Claim 1 wherein the pressure reducing
valve is provided with a valve plug or valve proper (f) which is secured to a
plate (2) loosely connected with a diaphragm in such a manner that when the
pressure reducing valve is relieved of pressure the valve proper cuts off communi-

page_text: cation with the gas holder as described and illustrated in Figure 2 of the
accompanying drawing.
