I, JEAN MARIE DURAFORT of N° 95 Boulevard de Beaumarchais Paris. in the
Republic of France Engineer do hereby declare the nature of this invention to be
as follows:-
In the siphon vessels employed for dispensing aërated liquids, the glass or
ceramic tube which extends down within the vessel nearly to its bottom is usually
cemented at its upper end to a metallic ferrule, the flange of which is pressed, by
screwing on the cap, tightly on a vulcanised caoutchouc washer. Owing to the
pressure of the liquor in the vessel, particularly if it is acidulated, and the contact
of the vulcanised caoutchouc with the metal, a chemical action is often set up by
which the liquor is rendered unwholesome or disagreeable in flavour.
This invention relates to means of avoiding this evil, by dispensing entirely
with the metallic ferrule, and providing that the substance which is in contact
with the vulcanised caoutchouc is either glass or ceramic material, or substance
such as gutta percha with which no chemical action is set up. According to one
construction, the glass tube itself is at its upper end formed with an outwardly
projecting flange which seats on the caoutchouc washer, and the glass tube itself
may at its upper end be expanded in diameter so as to form a bell mouth from
which the flange projects. Instead of making the bell mouth and flange as part
of the tube, it may be a separate piece of glass, ceramic material, gutta percha or
other suitable material, into the lower mouth of which the glass tube is cemented..

I, JEAN MARIE DURAFORT, of 95 Boulevard de Beaumarchais, Paris in the
Republic of France, Engineer, do hereby déclare 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 :—
In the siphon vessels employed for dispensing aerated liquids the glass or
ceramic tube which extends down within the vessel nearly to its bottom is usually
cemented at its upper end to a metallic ferrule the flange of which is pressed by
screwing on the cap tightly on a vulcanised caoutchouc washer. Owing to the
pressure of the liquor in the vessel, particularly if it is acidulated, and the contact
of the vulcanised caoutchouc with the metal, a chemical action is often set up
by which the liquor is rendered unwholesome or disagreeable in flavour. This
invention relates to means of avoiding this evil by dispensing entirely with the.
metallic ferrule and providing that the substance which is in contact with the
vulcanised caoutchouc is either glass or ceramic material, or a substance such as
gutta percha with which no chemical action is set up. According to one
construction the glass tube itself is at its upper end formed with an outwardly
projecting flange which seats on the caoutchouc washer, and the glass tube itself
imay at its upper end be expanded in diameter so as to form a bell mouth from
which the flange projects. Instead of making the bell mouth and flange as part
of the tube, it may be a separate piece of glass, ceramic or enamelled material,
gutta percha or other suitable material into the lower mouth of which the glass
tube is cemented.
Fig. 1 of the accompanying drawings shews, a vertical section of the upper end
of a siphon vessel with small lever in which the tube is provided with a metallic
ferrule in the ordinary manner and Fig. 2 shews the same part of a siphon vessel
with large lever, also having the ordinary metallic ferrule for the tube. Fig. 3
shews a glass tube constructed according to my invention with its upper end
enlarged and provided with a flange as a substitute for the tube shewn at Fig. 1;
Fig. 4 shews & glass tube without enlargement but provided with a flange, as a
substitute for the tube shewn at Fig. 2. Fig. 5 shews a glass tube having an
upper end formed of ceramic or other suitable material, into which the glass tube
is cemented.
. 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:
I
The use in siphon vessels of tubes made either entirely of glass or provided with
upper ends of ceramic or enamelled material, gutta percha and the like in lieu of
the glass tubes with metallic ferrules now in use, substantially as herein described.
