Improvements in Apparatus for Preparing Aerated Waters.
I, AUGUSTE EMILE HENRY LOZE, of 281, West Derby Road, Liverpool, in the
County of Lancaster, Aerated 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, reference being had
to the accompanying drawings :-
The object of this invention is to provide apparatus for the preparation of aerated
waters which shall be simple in construction and easily operated which will prevent
the gas generating liquid or materials from coming into contact with the water to
be aerated and which shall enable the aerating gas to be generated with little or no
admixture with atmospheric air the presence of which latter is the cause of the
flatness common in aerated waters.
For these purposes I make use of a receptacle for the water to be aerated con-
nected by a screw or other joint to a second receptacle which contains the gas
generating materials such as carbonate of soda, tartaric acid and water.
A valve
is provided between the two receptacles to prevent admixture of their contents, and
the second receptacle is provided with a grid or perforated plate or chamber upon
or in which, when the apparatus is being filled, the carbonate of soda and tartaric
acid or one of them rest. Suitable openings are provided in the receptacles for
insertion of the materials and outflow of aerated water.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side elevation of an apparatus under my invention in the form of a
gasogene suitable for table use, and Fig. 2 is a sectional view shewing the parts
inverted in position for being filled with water and materials. a is the receptacle
of any usual kind for the water to be aerated connected by a screw joint b to the
second receptacle c for containing the gas generating materials and water. d is a
perforated plate in the receptacle c upon which are placed the gas generating
materials. e is an opening through which the gas generating materials and water
are supplied to the receptacle c. The opening e is closed by a cap f. is a valve
between the two receptacles formed preferably of a rubber tube covering perfora-
tions h in a close ended tube i. The rubber tube will yield to any pressure in the
second receptacle so as to allow gas to pass into the receptacle a. j is a stand for
supporting the apparatus, k is any usual tap or siphon for the outflow of aerated
water from the first receptacle. Suitable packings are used for keeping the various
joints tight.
The operation is as follows:-The receptacles are detached from each other and
inverted, the receptacle a is completely filled with water, the space c¹ on one side of
the perforated plate d in the receptacle c is filled with water through the opening e
up to the perforated plate d, the rubber tube g being sufficiently tight to prevent
water escaping through the perforations h. The space c' on the other side of the
[Price 8d.1

page_text: perforated plate d is filled or nearly filled with gas generating materials which are
slightly moistened to generate sufficient carbonic acid gas to drive out the atmo-
spheric air from the space c², the cap f is then screwed on and the receptacle c is
connected, whilst still inverted, to the receptacle a by the screw b. The whole
apparatus is then placed upright as in Fig. 1 when the water in the space c¹ passes
through the perforated plate d amongst the gas generating materials in the space c²
thereby liberating the gas which passes by reason of its pressure through the valve g
into the receptacle a where it is absorbed by the water in the usual manner. The
valve g prevents any admixture of the contents of the two receptacles whilst allow-
ing free passage for the gas. It will be observed that all the spaces in the two
receptacles being filled with water, materials, or carbonic acid gas all atmospheric
air is excluded, thereby rendering the aerated water much more brisk, and with no
tendency to get flat when kept. It is necessary to allow a small quantity of the
water to escape from the receptacle a when sufficient pressure of gas is generated
to force it out so as to provide a space at a¹ above the level of the water as usual to
allow of free working of the gas but such space does not contain any atmospheric
air.
Fig. 3 is a sectional view of a modification of apparatus under my invention in
which a chamber is used instead of a plate for holding the gas generating materials.
c is the second receptacle, d is a chamber or box for holding the materials prefer-
ably attached to the cap f in any convenient way, and having perforations d¹ near
one end. In operation the chamber d is filled with the gas generating materials
and attached to the cap f; the receptacle c is filled with water to such a level that
the displacement caused by insertion of the chamber d into the receptacle c will
cause the water to rise nearly to the perforations d¹ as shown. The receptacle c is
then attached to a receptacle a and on inverting the whole the water flows through
the perforations d¹ thus liberating the gas as before described. Instead of both the
gas generating materials being put into the chamber d, one of them, say the
carbonate of soda, may be dissolved in the water in the receptacle c.
Although I have only shown the apparatus as applied for table use it will be
obvious that modifications of apparatus may be made suitable for manufacturing, on
a large scale without departing from my invention.
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 :-
First. In apparatus for preparing aerated waters the combination of two
receptacles connected together, a non return valve between the receptacles, and a
perforated plate, grid, or chamber, in connection with one of the receptacles all
operating substantially as and for the purposes set forth.
Second. In apparatus for preparing aerated waters the combination with the gas
generating receptacle of a perforated plate, grid, or chamber, for holding the gas
generating materials, or one of them, out of contact with the water when filling
and until the apparatus is inverted substantially as described.
