Improvements in Syphon Vessels or Containers for Liquids.
1, HERMANN RIESS, Engineer, of 123, Koepenickerstrasse, Berlin in the Empire
of Germany, 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 present invention refers to a carbonic acid gas outpouring apparatus for
beer and other fluids, which, contrary to previous beer outpouring containers,
works without any special pressure reducing valve, the draw tap heing connected.
in such maner to the carbonic acid gas inlet valve, that, when drawing, according
to the position of the handle, more or less carbonic acid is allowed to flow from the
carbonic acid container to the beer container, whereby it is possible, for example,
to draw beer as required more or less free of froth. The arrangement is. such
that, in drawing, first the outlet tap is about threequarters opened and then the
carbonic acid valve begins to gradually open, whilst, on the contrary, first the
carbonic acid valve and then the draw tap are closed. Furthermore the rotating
spindle of the draw tap is under the influence of a back pressing spring by which
means the tap is automatically closed when released. The apparatus permits,.
by simple touch, of a free and light opening and closing of the tap, so that the
least trace or the greatest quantity, can, as desired, be allowed to pass from the,
carbonic acid to the fluid to be poured out.
The invention is shown on the accompanying drawing in Fig. 1 by a vertical
section and in Fig. 2 by a plan. The new pouring apparatus is fitted in the hollow.
cover a acting as the receiver for the carbonic acid. The edge of, the cover a
rests on the fluid container with which it makes an air tight connection by means
of a rubber joint ringe and any desired form of wire saddle or other fastening d.
The hollow cover a is provided centrally with the outlet pipe e with air tight..
gland e¹, in which is inserted the glass tube f extending down to the bottom of
the retainer b. The tube e communicates at the top with the body of the tap g
and the spout h. The valve spindle i can be lowered and raised in g by means of
the strongly inclined thread k. In the upward direction the tap body is
hermetically closed by means of the packing and the screw sleeve /. A powerful
spiral spring m acts in such manner on the valve spindle that this is always
brought back to its highest position, the valve thus being always forced against its
seat. The upper end of the valve spindle is fitted with the handle n and the
horizontal plate o in the form of a sector of a circle. The outer edge of this sector
plate o moves over the pin 2 of the carbonic acid valve. The pin p bears on a
rubber membrane 7 which is attached between the rim r of the valve box r and
a disc s laid thereon, whilst the latter is firmly clamped against q by means of a
screw sl having a central bore to take the forcing pin. Underneath, the rubber.
membrane q is the valve spindle with the valve the joint ring u and the side
groove. A spiral spring keeps the valvet closed. The bottom of the valve
chamber is provided with the bore w which is in connection with the container b
by means of the tube x. The tube x is fixed to an addition y to the hollow cover a, into
which the valve chamber r is screwed in from above. For the purpose of making a
2:

page_text: tight joint between the two a rubber dise is inserted, which is pierced with one
or more holes. These holes lie in the same circle as the ring channels 7 and y
in and y. The hole w and the tube are so arranged that they also open into
the channels 2 and y².
The hollow cover a is furthermore provided with the addition 1 into which is
screwed the chamber 2 of a back pressure valve 3. The latter has a joint disc 4
and is constantly forced against the opening 6 by a spiral spring 5, which opening
may be closed by a screw cap 7. The addition is provided underneath with the
opening 8.
In order to fill the hollow cover a with carbonic acid the cap 7 is unscrewed and
the conducting tube off a carbonic acid flask is connected to the thread of 4. The
back pressure valve 3 permits the inlet but not the outlet of the carbonic acid.
After the hollow cover a is filled, into which the carbonic acid passes through the
opening 8, the cap 7 is again screwed on.
In order to draw the liquid, the handle n is turned to the right,.. whereby the
spindle is screwed down and the valve 2 lowered from its seating . A com-
munication is thus formed between the outlet spout and the glass tube f and
thereby with the container b. With the spindle i the plate o is at the same time
lowered and this, when the outlet tap is about three quarters open, meets the pin p
and presses it down. The pin p then effects an outward curving of the rubber
membrane downwards, whereby, with compression of the spiral spring v, the
valve is lowered from its seat. The carbonic acid can now pass through the
groove 2 of the valve spindle t, out of a into the valve chamber n. Thence it
flows through the hole into the circular channel and from this through the
holes in the joint disc z into the circular channel y³, and out of this through the
tube into the container forcing the fluid through f and 2 into the spout h.
By turning the handle more or less open, a greater or less quantity of carbonic
acid can be allowed to pass into the fluid container.
If it is noticed that the outflow is too strong the handle n is left to act under
the influence of the spiral spring m until the proper rate of outflow is obtained.
The touch of the hand enables the proper position of the handle to be easily and
quickly effected.
The arrangement of the circular passages or ring channels 2 and y³ is such,
that, in any position, of the dise bore holes and the chamber bore holes w,
which may be disturbed by the screwing of the chamber into the cover addition y,
the communication between a and b is insured.
The whole apparatus is fitted together in such manner that the outlet tap as
well as the carbonic acid valves (for filling and outlet) may be unscrewed from the
cover a and their separate parts laid bare, which is of great advantage for purposes
of cleaning and repairing.
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. A syphon for liquor with hollow cover serving as carbonic acid container
characterised by the draw tap, provided with the downward screwed valve, trans-
ferring its movement, in opening and closing, by means of a sector slide and
press plate, on the carbonic acid inlet valve, thus simultaneously opening and.
closing the latter, it being arranged that the carbonic acid valve opens later
and closes earlier than the draw tap operating it.
2. With the liquor syphon characterised in Claim 1, the use of an outlet draw-
valve automatically closing by means of a spiral spring (m), for the purpose of
effecting a quicker closing of the carbonic acid valve when the outflow is too great.
3. With the liquor syphon according to Claim 1, the use of a carbonic acid valve,
the outlet opening of which (w) is by means of circular or ring channels (2 y²)
and by holes in the jointing disc (2) in communication with the outlet pipe (e)
of the liquor container (b), for the purpose of making this communication in-

page_text: dependent of the position which may be assumed by the joint ring (2) and the
outlet openings (w).
4. A syphon for fluids arranged and constructed substantially as described
with reference to the drawings.
