An Improved Portable Apparatus for
Year: 1897

page_text: Date of Application, 14th June, 1897
Complete Specification Left, 8th Feb., 1898-Accepted, 9th Apr., 1898
I, VICTOR DURAFORT, fils, of 162, Boulevard Voltaire, Paris, France, Engineer,
do hereby declare the nature of this invention, to be as follows:-
My invention relates to an improved portable apparatus for the production of
small quantities of soda water.
The said apparatus consists of a glass vessel or bottle provided with a syphon-
head the same as those now used on bottles containing aerated waters. The bot-
tom of this bottle terminates in a neck which fits into the mouth of a reservoir
forming the foot or base of the apparatus, and said neck rests upon a rubber washer
located in a flange on the reservoir, so ensuring air and water tightness. Into
the mouth of the reservoir, is screwed a nut which holds the entire contrivance
together, and which forces the bottle neck against the washer by pressing upon a
flange formed on said neck. This latter is closed by a cork plug having a central
passage which is closed at top by a perforated metal plate, and at bottom by a
piece provided with 4 horizontal channels arranged at right angles.
Through these channels, the central passage, and the perforated metal plate,
the reservoir communicates with the bottle or vessel.
To charge the apparatus, the bottle is detached from the reservoir, and into this
latter specially compressed tabloids, pellets, or pastilles, are introduced. The
bottle is then turned upside down and is filled with water. The apparatus is then
put together while keeping the bottle in its filling position. It can then be
turned upright, but prior to so doing it should be held horizontally for a moment
or so to permit the exchange of small quantities of water and air between the
bottle and the reservoir.
Directly the water comes into contact with the tabloids, or the like, carbonic
acid is evolved, passes through the orifices in the plug, and is then absorbed by
the water in the bottle, so producing the so called soda water.

An Improved Portable Apparatus for the Production of Soda Water.

[Price 8d.]

page_text: to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying drawings and to
the letters and figures marked thereon, that is to say :-
My invention relates to an improved portable apparatus for the production of
small quantities of soda water, or other like aerated waters, and will be readily
understood on reference to the accompanying drawing.
The said apparatus consists of a glass vessel or bottle 1, provided with a syphon
head 2, the same as those now used on bottles containing aerated waters. The
bottom of this vessel or bottle terminates in a neck 3, which fits into the mouth
or socket 4, of a reservoir 5, forming the foot or base of the apparatus.
The insertion of the neck 3 is limited by means of a flange 6 formed on the reser-
voir 5, and rests upon it through the intervention of a rubber washer 8, designed
to ensure air and water tightness to the apparatus.
A nut 7, screwed into the mouth or socket 4 holds the entire contrivance together,
and forces the neck 3 on to the rubber washer 7 by pressing upon a flange 9 formed
on said neck. This latter is closed by a cork plug 10 having a central passage 11
which is closed at top by a perforated metal plate 12, and at bottom by a piece 13
provided with four horizontal channels 14 arranged at right angles to each other.
The reservoir 5 communicates with the bottle or vessel through the channels 14,
the central passage 11, and the perforations in the plate 12.
To charge the apparatus, the bottle is detached from the reservoir 5, held
upside down, and then filled with water. Into the reservoir specially compressed
tabloids, pellets, or pastilles, are introduced. The apparatus is then put together,
while keeping the bottle in its filling position. It can then be turned upright,
but prior to so doing, it should be held horizontally for a moment, or so, to permit
the exchange of small quantities of water and air between the bottle 1 and the
reservoir 5.
Directly the water comes into contact with the tabloids, or the like, carbonic
acid is evolved, passes through the channels in the plug 10, and is then absorbed
by the water in the bottle, so producing the so called soda water.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1. A portable apparatus for the manufacture or production of small quantities
of soda water, or the like aerated waters, characterized by a reservoir in which
carbonic acid is produced, and which reservoir is connected to a vessel or bottle
by an air and water tight arrangement, said reservoir and vessel communicating
with one another through a perforated plug, substantially as described.
2. My improved portable apparatus for the production of soda water, substan-
tially as herein before described with reference to the annexed drawing.
