Year: 1887

page_text: LUTHER GEORGE CHINNERY, and SWARTZ MARTYN CHINNERY, Engineers, both of
14 Almack Road, Clapton, E. London, in the County of Middlesex England, do
hereby declare the nature of this invention to be as follows:-
Our Invention has for its object, Improved Apparatus for making, and supplying
Aerated Drinks, and in order to do this-we construct it, as follows, viz. we make
a vessel of suitable metal, in two parts, similar in shape to an ordinary Soda-water
"Condensor," (or cylinder) united by ordinary flanges, and bolts, and nuts, having
enclosed within it for a Water-chamber, a glass-neck-less Bottle, (or Jar) having at
the bottom of said bottle, about the centre, a small boss, with aperture for the insertion
of a long internal tube rising nearly to the top, and a larger hole at the top, for the
insertion of the Water, and acid, and alkali; the above-mentioned tube is secured to
a tripod, or stand fitted into the lower half, on which the bottle rests, the aforesaid
bottle is made slightly smaller in diameter than the inside of the metal cylinder, so as
to permit the carbonic-acid-gas to surround the bottle outside, as well as inside, thus
equalising the pressure internally, and externally-the space (a few inches) beneath
the bottom of the bottle, and the metal cylinder we use as a gas-chamber-for the
generation of carbonic-acid-gas-by means of Acid and Alkali, which we insert
therein from the top of the vessel, through an aperture therein, having an hermetically
sealed cap, or lid; In this said gas-chamber we insert an agitator, having a vertical
spindle, descending through a stuffing-box-at the bottom of the vessel said agitator
being prevented from rising by a lock-nut, or spring, under the gland, with adjustable
collar, and the spindle having a square, or at the outside end fitting into the
base, (or a socket) to prevent it turning round, and around which agitator we cause
the whole vessel to revolve, on its axis. As a means of support, of such apparatus,
we have a boss (the inside of which, answers to the stuffing-box)-projecting from
the bottom of the vessel, and fitting into a stand, having a central hole, on which
"Hats

stand, the whole vessel revolves. Near the bottom of the gas-chamber we have a
hole with plug, to remove the remains of former " charge of Acid & Alkali.
We also fit a draw-off Tap near the top of the vessel, having an internally
descending tube.
The whole of the above vessel we subject to an internal hydraulic pressure
of 300 lbs., per square inch.
I " charge the apparatus as follows-having filled the Water-chamber, I deposit
the acid, and alkali, through the tube into the gas-compartment beneath, followed by
a small quantity of water to generate the gas, close the aperture at the top, and if
desirable, revolve the apparatus on its axis, and draw off the liquid as desired.

Improved Apparatus for Making and Supplying Aërated Drinks.
We, LUTHER GEORGE CHINNERY and SWARTZ MARTYN CHINNERY, both of
14, Almack Road, Clapton, in the County of Middlesex, Engineers, do hereby
leclare 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 :-
Our invention relates to what are known as gazogenes or apparatus for making
acrated beverages and it comprises the improvements hereinafter described.
In the accompanying drawing,
Figure 1 shews in central vertical section, a gazogene constructed according to our
invention, and
Figure 2 is a detached view of a slightly modified arrangement of part of the
apparatus.
a is a cylindrical vessel having semi-spherical ends and composed of copper or
other suitable metal. This vessel is formed in two parts b, c having flanges d, d at
their adjacent edges, the said flanges being united by bolts and nuts e, as shown in
the drawing, or by any other suitable micans, and having a packing ring between
them to forin a tight joint.
The lower part c of the vessel has formed integral with it a boss g which is fitted
into and adapted to rotate in a bearing in the stand has shown. The upper end of
the vessel is provided with an aperture which is normally closed hermetically by a
cover which, as shown, is held in place by a stirrup and screw k, a packing ring
being placed between the cover and the vessel to form a tight joint.
m is a water chamber or vessel of glass, porcelain, or enamelled metal, which vessel
is placed within the chamber a, and which is carried by a plate in the lower part c
of the chamber, the said plate being supported upon lugs o, o.
At the bottom of the said chamber m at the centre is a small boss having an
aperture for the insertion of a long internal tube p which rises nearly to the top of
the said chamber, and is secured by a screw collar, or it may be secured in any
other suitable manner.
If desired the tube p may be formed in one piece with the chamber m.
The aforesaid chamber is slightly smaller in diameter than the interior of the
metal cylinder, so as to permit the carbonic-acid-gas to surround the chamber
outside, as well as inside and thereby equalize the pressure on the interior and
exterior of the said glass chamber.
The space beneath the plato n serves as a chamber for the generation of carbonic-
acid-gas by means of acid and alkali, which we insert therein from the top of the
metal vessel in the manner hereinafter described, or it serves as a gas-washing-
chamber when prepared carbonic-acid-gas is used instead of acid and alkali, which
prepared gas we insert or inject by attaching a metal flask containing the gas to the
lower part of the vessel.
:

page_text: In the gas-chamber is located an agitator having two arms, as shown, or any
other desirable number of arms. This agitator has a vertical spindle s descending
through a stuffing-box formed in the boss g, a gland t¹ being placed at the bottom of
the said boss for compressing the packing in the stuffing box.
A spring u is placed on the spindle s and bears at one end under the gland and at
the other end upon an adjustable collar s fixed to the lower part of the spindle, the
said spring serving to prevent the agitator from rising. As shown in the drawing,
the spindle is adapted to be oscillated by means of the handle s secured to tho
bottom of the spindle. If desired, however, the said spindle can be suitably secured
so that the agitation of the liquid within the vessel is effected by rotating the latter
relatively to the agitators.
In addition to the lower agitator, we find it advantageous to employ an agitator v
in the upper or water-chamber. This second agitator v is attached to the upper
end of a vertical tube w passing through the tube p fixed to the water-chamber m,
the lower part of which tube w is connected to the agitator, and secured by a
bolt wor a pin. The tube w is in figure shewn enlarged at its lower end and
has slots or apertures to therein for the purpose of permitting the acid and alkali
which are passed through the tube w from the opening i to find egress into the
lower or gas-chamber, but in the case of larger size apparatus we prefer the
arrangement shewn in figure 2 in which the bottom of the tube opens direct into
the lower chamber and is connected to the agitators, by arms, ². This
arrangement allows of the acid and alkali passing into the lower or gas-chamber
without risk of clogging the tube w.
The arms of the agitator extend down into the chamber m, so that on vibrating
the lever s², not only will the chemicals in the gas-chamber be stirred up, but at
the same time, the gas contained in the upper chamber will be thoroughly mixed
with the water contained in the chamber m.
By operating the agitators from the bottom of the apparatus, the escape of gas
is prevented, only water being near the stuffing box.
Near the bottom of the gas-chamber, we forin a hole fitted with a small plug »
by removing which the remains of the exhausted charge of acids and alkali can
be discharged.
y is a draw-off tap which is connected with the glass chamber at the bottom.
Or the cock may be attached to a tube depending into the glass chamber through
the opening at the top thereof or through a separate opening formed for the
purpose.
In charging the apparatus, the water chamber m is first filled and then the acid and
alkali are inserted through the tube into the gas-chamber followed by a small
quantity of water to generate the gas. The aperture at the top of the vessel is then
closed and the agitators are operated, after which the liquid which is now aërated can
be drawn off as required.
By mounting the vessel on a stand in the manner hereinbefore described, the said
vessel can be turned so that liquid can be drawn at either side without necessitating
the moving of the whole apparatus.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
(1.) A gazogene or apparatus for the manufacture of aërated beverages comprising
n vessel divided into two compartments, the upper one of which is provided with a
glass chamber (of slightly smaller diameter than the interior of the metal cylinder)
for containing the liquid to be aürated, while the lower serves for the generation
of gas, and an agitator or agitators, the whole arranged and operating substantially
as described.
(2.) In a gazogene the employment of an internal glass chamber for con-
taining the liquid to be aerated, the said chamber being arranged in such a

page_text: manner that the gas pressure acts thereon at all points both internally and externally,
substantially as described.
(3.) A gazogene mounted upon a stand in such a manner that it can be rotated,
substantially as described.
(4.) In a gazogene provided with an agitator or agitators, the arrangement of the
same in such a manner that it or they can be operated from the base of the apparatus
for the purpose specified.
(5.) The improved gazogene or apparatus for the manufacture of aërated beverages
constructed and arranged substantially as hereinbefore described and illustrated in the
accompanying drawing.
