COMPLETE SPECIFICATION.
Improved Stopper and Detachable Syphon Head for Bottles
Containing Effervescent Liquids.
I, JAMES SCHULHOF, of the Sanitas Soda Water Factory, 51, Gisella Strasse,
Buda Pesth, Hungary, Manager, 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 a valve for bottles for soda water and
other effervescing beverages, and a syphon head which can be screwed on this
valve
The invention is illustrated in the accompanying drawing in which:
Figure 1 is a section of the valve casing o shewing the valve e and the screwed-
on syphon head d.
Figure 2 is a section like Figure 1 but without the syphon-head d and having
a rubber tube ¹ instead of the spring k.
Figure 3 is a section on the line II of Figure 1.
Figure 4 is a section on the line II-II of Fig. 1.
Figure 5 is a section on the line III-III of Figure 1.
Round the lower part of the neck of a suitable bottle is placed a bipartite,
partially threaded ring m made of brass, celluloid, zinc or the like, over which
is screwed a casing o made of the like material and having internal screw
threadings. A metal tube 7 in one piece, passing up through a circular extension
to the neck of the bottle, widens out inside to form a fulcrum for the spring k.
A rubber tube with perforated holes 1 (Fig. 2) can be used instead of the
spring. The tapering end of the tube 7 receives a glass tube n giving it
thereby the requisite stability. The top of the valve casing o is screw threaded,
and on this the syphon head can be screwed.
A cylindrical opening in the valve casing o is fixed for the seat of the valve c
moving up and down. The latter has three curved grooves or recesses (Figure 5)
for allowing the liquid to pass. The valve e has also a prolongation e¹ on the
top which is of a smaller diameter and is also provided with three curved
grooves (Figure 4) and the top of this valve prolongation reaches far enough
to abut on the lower end of the presser bar 62 and can thus be opened In the
valve. casing o rubber washers for the valve e and also f3 for the tubular
neck of the bottle are arranged.
The syphon head d which can be screwed on and off the valve casing o serves
to open and shut the valve e and consists of the following:
:-
The lower rim of the syphon head is provided with threadings inside in
order to be able to be screwed together with the outside threadings of the
valve casing o. Through the top c, also secured by means of a screw threading,
passes the presser bar b. 61, 63 which by means of its lower end 62 opens the
valve when it comes in contact with it. At the top of the bar is placed the
presser knob a, the bar b having a circular plate which is fitted to the top c
forming a stop and thus preventing the bar from being drawn out of the syphon

page_text: head d. The part 2 of the bar is like the valve e provided with three grooves
and likewise with the rubber spring buffer or washer f the latter for the purpose
on the one hand of raising the bar after it has been depressed and returning the
knob a again into its normal position, and on the other hand of preventing the
liquid mounting higher than through the opened valve e and of forcing it to
flow out through the discharge tube h. There is also a washer f¹ between the
syphon head d and the valve casing o.
The operation of the device when in use is as follows: to t
When the syphon-head d has been screwed on to the valve casing o and the
knob a is pressed downward, the bar ferater on effervescing drink filled
bar-fixed to the knob. at pushes down the
valve e which causes it to open.
in the usual manner flows out of the glass tube n by means of the three grooves
round the valve e and those of the bar until it mounts to the envelope f,
which prevents it from rising higher and it is consequently forced out through
the discharge tube h. If the knob a is then released, the valve e closes by aid
of the spring or of the rubber tube k, and the bar b, 1, 7, is restored by the
rubber envelope f to its original position.
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:
The improved valve for bottles for soda water and other effervescing liquids
with a detachable syphon head characterized by a valve (e) placed in the valve
casing (o) which valve moves up and down and is kept closed by means of a
spring (k) or rubber tube (¹) respectively, and which can be opened by means
of the syphon head d raised or depressed by aid of the bar b, 1, 2, substantially
as set forth.
