Improvements in Syphons or Seltzogenes for Making Aërated
Waters.
1, RAYMOND PRAX, of 15bts, Boulevard St. Denis, Paris, in the Republic of
France, Engineer, do hereby declare the nature of this invention to be as
follows:-
The improved syphon or apparatus for making acrated waters which forms the
subject of my present invention, consists of a vessel, preferably of glass, the upper
part of which is provided with a head containing a valve and lever, and a discharge
spout, of the usual well-known kind, as well as a glass or other tube descending
nearly to the bottom of the vessel.
The lower end of the vessel is open and is provided with a metal ring, screwed
inside and projecting sufficiently, so that a second ring screwed externally can be
screwed into it. This second ring is fixed round the neck of a lower shallow vessel
having a flat bottom which forms a stand for the apparatus, a ring of india rubber
or other material being fitted between the top of the second ring and the bottom
edge of the upper vessel to make a tight joint between them.
The mouth of the lower vessel is fitted with a separate cover or stopper
perforated with small holes.
In order to use the apparatus, to make aërated water, the lower vessel is
unscrewed, and the upper one which forms the syphon is inverted and filled with
water to about the level of the open end of the central tube. The usual powders
to generate gas are introduced into the lower vessel, the separate stopper being
then replaced, and the lower vessel screwed firmly upon the upper one. The entire
apparatus is then inverted to its normal position, and the water penetrating into the
lower vessel, gas will be generated, which will rise in bubbles and thus saturate the
water in the syphon.

I, RAYMOND PRAX, of 36, Rue Saint Louis, Montauban, (Tarn-et-Garonne),
France, late of 15bs Boulevard St. Denis, Paris, in the Republic of France,
Engineer, 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 this invention is to produce a syphon or seltzogene adapted to
manufacture its own aerated water.

page_text: In the accompanying drawings Fig. 1 represents an elevation, and Fig. 2 a
vertical central section, partly in elevation, of a syphon-bottle embodying the said
invention.
The upper part of said syphon-bottle has the usual construction. The lower
part is removable and adapted to contain the powders which, when moistened,
evolve the gas required. Herein lies the novelty of the invention. The drawings
illustrate that construction of this lower part which I have found most practical
and satisfactory. A metallic band or ring 6 is rigidly fastened to the lower end of
the body s of the syphon-bottle, and is screw-threaded on the inside to receive an
externally-screw-threaded inner ring a. Annular rubber packing is interposed
between the lower end of the glass body s and the ring a, and also serves to preserve
the said metal rings from contact with the liquid contained by said bottle. The
ring brests on the removable hollow glass base c, the inner ring a being rigidly
fastened to the latter, so that the said base may be screwed in and out at will. The
interior receptacle or chamber r of the said base is covered by a lid g, which is
perforated at o.
The interior tube of the syphon-bottle is designated by p.
When the base c is unscrewed, the lid g is taken off, the receptacle r is charged
with the powders, and the lid replaced. The empty body s is then inverted and
filled with water to the height of the said tube in this position. The said base is
then also inverted and screwed into the said body and the whole bottle is set
upright. The water will now pass down from the interior of the body s through
the perforated lid g to the powders within the chamber r. In consequence the
predetermined chemical combination will take place, evolving gas, which will rise
in the form of bubbles through the said plate into the mass of water, aerating it
as needed for the action of the syphon-bottle and for drinking. This construction
dispenses with sulphuric or other acid, making a great saving in expense without
loss of gas by escape. All salts and other solid deposits resulting from this process
or the impurity of the powders will remain in the bottom of the receptacle r and
not mix with the liquid.
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-
The bodys provided with syphon attachments and the fixed ring in com-
bination with the hollow base c having a perforated removable lid g a fixed
surrounding ring a adapted to screw into the ring b, and a packing ring arranged
substantially as set forth.
