Improvements in Siphon Vessels for Aerated Liquids.
We, EDUARD LUDWIG HASSENBERGER, of III Hauptstrasse 22 Vienna,
Manufacturer, and ROSA STEGER and Theodor GLASER, both of the Firm of
Max Glaser of II Kleine Schiffgasse No. 26, Vienna, Austria, Manufacturers, 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 an improved construction of the head-pieces and
discharge nozzles of siphon vessels for aerated liquids, whereby such liquids are
prevented from coming into contact with the metal parts of the head piece, which
is thus protected against the injurious action of the carbonic acid gas, whereby the
deterioration of the water by metallic salts is prevented.
We will describe the construction of the improved head-piece for the above
purpose with reference to the accompanying drawing, in which
Figs. 1 and 2 shew vertical sections of two different modifications thereof.
a is the ordinary casing of the head piece, which is preferably of tin or pewter
and is provided with a trigger lever b and discharge nozzle c; within a hollow in
this casing is fitted a block d of glass, porcelain, celluloid, clay, papier maché or
other suitable material that will not be attacked by carbonic acid, which block d
has a central bore for the passage of the valve spindle f and has on its underside a
recess in which is formed the seat for a valve h.
This valve and its spindle may either also be made of glass, porcelain, celluloid,
or other material not attacked by carbonic acid, or it may be made of metal either
enamelled or silver plated.
The lower projecting rim of the body d bears against a ring washer i, between
which and another ring k is situated the flange-like rim of the glass siphon pipe 1
which pipe may be formed conically at its upper end.
The clamping of the glass pipe between the two washers or tightening rings is
effected by the head m of the siphon vessel which is pressed in the usual manner
against the ring k by a nut n, composed of two parts, screwed into the internally
threaded casing a and bearing against the lower rim or edge of the head m.
The valve spindle f passes through a tightening disc upon the body d, upon
which disc bears the trigger spring p and which prevents the discharging of liquid
into the space above the body d.
In the discharge nozzle c is located a tube 9 of glass, porcelain, celluloid, papier
maché or of any other suitable material proof against carbonic acid, which nozzle
communicates with the body d. It is either formed separate from the latter as
shewn at Fig. 1, where the tube is cemented to the body, or it is integral with the
same as at Fig. 2. In this modification the casing a c is cast around the
part a q.
The valve may be formed as a conical valve as at Fig. 1, or a ball valve
as at Fig. 2, or of any other form, with or without a covering of caoutchouc; the
seat is formed in a corresponding manner.
As the tightening rings are also made of lead-free caoutchouc the liquid does
not come in contact with the metal parts, so that no noxious metal salts can be
formed and the closure of the siphon is consequently of a very hygienic nature.
It is obvious that instead of a trigger b, a knob on the top of the siphon head
may be used for lifting the valve / from its scat.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A head piece for siphon vessels for aerated liquids wherein a body d and
tube located in the metal casing a and discharge nozzle c are constructed of a
material that is not attacked by carbonic acid, such as glass, porcelain, clay,
celluloid, or papier maché, whereby the contact of the liquid with the metal parts
of the head piece is prevented, the valve and valve rod f being either also
constructed of the said neutral material or made of enamelled or silver plated
metal, substantially as described.
2. In a head piece for siphon vessels such as is referred to in the first claim,
securing the glass siphon tube 7 by pressing its flange between two annular
washers i and k situated between the head m of the siphon vessel and the lower end
of the body d, substantially as described.
3. The modified construction of the head-piece referred to in the first. claim
wherein the body d and tube q are formed in one piece, the casing a and nozzle c
being cast round these parts, substantially as described.
