J, ANTON KORETZ of 15, Johannesgasse, Währing near Vienna, in the Empire of
Austria, Soda-water manufacturer, do hereby declare the nature of this invention to be
ns follows:
This invention relates to siphon bottles for containing soda-water and similar
nerated liquids.
The invention has for its object to entirely avoid contact between the beverage
charged with carbonic acid and metallic parts of the stopping mechanism or head.
According to the said invention, the body or shell of the said head is made of
ceramic material, by preference of porcelain, and for affording means for suitably
connecting such a porcelain head to the bottle, a metal ring is cast into the lower-
most cylindrical portion of the head and this metal ring is provided with internal
screw-threads.
Above the metal ring, the inner hollow space of the head is provided with a
shoulder, and between this shoulder and the top surface of the bottle-neck a
tightening dise of India-rubber is placed, this disc having a central hole and being
made integral with a short rubber tube, which projects downward into the neck of
the bottle, and into which the glass pipe is sprung for the ascent of the beverage.
The valve, controlling the communication between the space above the said rubber
disc and the delivery nozzle, is made of rubber, and as, owing to the nature of the
material of which the head is made, it would be more or less difficult to guide the
valve-stem, a loosely guided valve stem is combined with a globular valve, which
tightly fits its seat notwithstanding the possible deviations of the valve-stem in its
guide. The said globular valve consists of a nut screwed to the lower end of the
valve stem and coated with a thick layer of rubber, having a spheroidical outer
surface.
Moreover, as it would be difficult to fix into the ceramic material a pivot pin for the
lever by which the valve is operated, the said lever passes freely through slots in

page_text: the shell and in the valve stem, and on a point diametrically opposed to the slot
of the shell, the upward curved end of the lever enters a correspondingly shaped
rotch formed in the side of the cylindrical passage or space, wherein the valve-
stem and its coiled spring moves. The lower edge of the slot of the valve-stem,
on which edge the lever rests, is shaped like a knife-edge of a balance and on the
side of this knife-edge facing the aforesaid notch, the lever is provided with a
downward extending projection. This projection and the upwardly curved pivoted
end of the lever prevent its being pulled out under normal circumstances.

page_text: I, ANTON KORETZ of 15 Johannesgasse, Währing, near Vienna Soda-water
manufacturer 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 has for its object to entirely avoid contact between the beverage
charged with carbonic acid, and contained in the so-called syphon-bottles with the
metallic parts of the stopping mechanism or head.
According to the said invention the heads of the said syphon bottles are made of
ceramic material preferably porcelain, and for affording means for suitably connecting
the said head to the bottle, a metal ring is cast in the lowermost cylindrical part of
the head, the said ring being provided with internal screw-threads for securing the
head upon the bottle.
As by reason of the nature of the aforesaid material the production of an exact
guide for the valve stem would be expensive and troublesome the valve is of
spheroidal form and made of India-rubber thereby enabling the valve to be properly
pressed against its seat even when it slightly deviates from the central position.
Another feature of the said invention is the mode of connecting the glass pipe
through which the aërated liquid rises. The joint between the head and the bottle
neck is rendered tight through the medium of an India-rubber disc having a central
hole from which a short pipe extends downwardly, and this pipe is slid upon the upper
end of the glass pipe.
The accompanying drawing represents a vertical section of the upper part of a
syphon bottle with a orcelain siphon head attached and constructed according to the
said invention.
a is the siphon head of porcelain and the metal ring which is cast in the lower
part of the said syphon head. The said head a is provided with internal screw-threads
in order to enable it to be screwed upon the screw-threaded neck of the bottle c.
The joint between the head and bottle is made tight by means of the India-rubber
disc d, from the central hole of which extends a short pipe d₁ downwardly into the
bottle neck. This pipe d, is slid upon the glass pipe e through which the beverage
impregnated with carbonic acid rises. In the upper surface of the washer or
disc
is provided a depression d, which affords the valve above, the necessary freedom
of movement. In this valve a nut g is placed upon the screw-threaded lower part of
the valve stem and is provided with an India-rubber covering on all sides. The
upper part of the India-rubber covering which is perforated to enable the passage of
the valve stem, is of spheroidal shape in order to enable the same to bear tightly
against the lower edge of the channel a¹ (in which the valve stem is supported) in
all possible positions of the stem which is only approximately guided.
At a short distance above the valve h the channel a, for the outlet of the beverage
contained in the syphon bottle branches off from the channel a₁ and a little further
upward the latter channel is provided with an enlargement az.

page_text: The said enlargement a3, on the one hand serves for the reception of the helical
spring which keeps the valve closed, and on the other hand forms an offset for the
support of a washer or disc k of India-rubber. This disc k which is continually held
down by the spring and which bears closely against the valve stem f prevents the
liquid passing upwards when it is poured out.
At the upper end of the valve-stem is a head f₁ which is guided but with con-
siderable play in the channel or enlargement us, and against which the helical spring j
bears. The head f₁ which carries a porcelain cap n above, is also provided with a slot
through which extends the lever m for opening the valve.
The lever m upon whose outer end the thumb is intended to be placed when
operating the syphon is provided with a cover or sheathing m₁ of porcelain and is
supported at its other end m, which is pointed and bent upward in a notch a, in the
wall of the channel as and protrudes from the head through a slot a, arranged
diametrically opposite the notch a...
As the pressure of the spring; also forces the lever m against the upper end of the
slot the upward movement of the valve stem is limited by the said lever m in this
position which is shown in the drawing. In order to prevent the lever m falling out
in the ordinary use of the syphon a downwardly projecting part m, is provided on the
lever besides the upwardly bent end ma, by the side of which part the upwardly
projecting bearing or butt piece fe has its place in the head f₁ of the valve stem. If
however the valve stem is entirely pressod down, the lever m can be drawn out. As
will be readily understood, this arrangement is adapted to the nature of the material
which renders the use of a pin or pivot for the lever inconvenient and impracticable.

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
First. The improved syphon head which is made of porcelain or other ceramic
substance, and in which a metal ring is cast below in order to enable the screw
threads for the connection with the bottle to be cut in the same.
Second. In syphons arranged as above described the tightening of the joint
between the head and the bottle by means of an india-rubber disc having a central
hole and from which a short pipe extends downwardly for the insertion of the glass
or tube.
Third. In syphons arranged as above described, a valve, the stem of which is
loosely guided in a channel of the head, and which consists of a nut screwed upon
the stem and having an india rubber covering which is of spheroidal form above,
so that despite the inaccurate guide the valve will always fit tightly against its seats.
Fourth. In syphons arranged as above described in the first claim, a pressing lever
extending through a slot in the valve stem, with its upwardly bent end loosely into a
notch in the wall of the guide channel, so that the arrangement of a pin or pivot for
the lever in the ceramic substance is obviated.
