PROVISIONAL SPECIFICATION.
Improvements in Portable Apparatus for Making Aërated Beverages.
I, LAWRENCE SAUNDERS, of 26, Budge Row, Cannon Street, in the City of
London, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention consists of improvements in apparatus for aërating and supplying
beverages of various kinds.
I accomplish this by constructing a reservoir of metal selected and proportioned
to bear the requisite pressure of gas and so prepared that no possible corrosion can
occur by contact with water acidulated or otherwise. I make this chamber in two
parts provided with flanges so that they may be securely joined together in the
ordinary manner by bolts and nuts.
I provide in the upper part of the upper chamber three holes one for supplying
the reservoir with water and for putting in the materials to generate carbonic acid
gas, another, for the insertion of a spindle to carry revolving agitators and the
third for fitting a suitable safety valve and pressure gauge.
In the bottom of the lower chamber I provide a hole for the passage of a draw-off*
pipe which I pass upwards through the dividing plate into the upper chamber in
such a manner as not to interfere with the rotating action of the blades or agitators
which I attach to a spindle passing through the upper and lower chambers.
The agitators in the lower chamber are so made as to thoroughly agitate the
materials used for generating gas.
Through the plate which divides the upper and lower chambers I pass another
tube of suitable dimensions to convey into the lower chamber the materials used for
generating gas.
The upper end of this tube opens about an inch below the hole in the top of the
upper chamber so that by means of funnels the one hole can be used for conveying
materials into the lower chamber or for supplying the upper chamber with water.
The draw off pipe on passing out of the bottom of the lower reservoir is made with
a ball joint to communicate with a number of pipes corresponding to, and opening
into, an equal number of vertical tubes arranged to resemble architectural columns
outside and round the reservoir.
The interior of each of these columns is divided into two chambers, the upper
chamber for storage of syrups, mineral salts, essences, and the lower chamber for
receiving aërated water from the central reservoir. From the lower end of each
column a pipe and a draw-off tap is provided connected with a smaller pipe which
opens into the syrup chamber and supplies the aërated water with the exact
proportion of syrup required. Each of these draw-off taps is constructed to make
an electrical contact which completes the circuit of a battery operating an electro-
motor which I attach to the outside of the upper part of the central reservoir, and
connect to the spindle which passes through the two chambers of the said reservoir,
and carries the blades or agitators.
By this means violent agitation is set up on turning the tap to draw off the
aërated beverages.

Improvements in Portable Apparatus for Making Aërated Beverages.
I, LAWRENCE SAUNDERS, of 26, Budge Row, Cannon Street, in the City of
London, Civil 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 :-
My invention consists of improvements in apparatus for aerating liquids and
supplying beverages of various kinds.
I accomplish this by constructing a reservoir of metal or any other suitable
material selected and proportioned to hear the requisite pressure of gas and so
prepared that no possible corrosion can occur by contact with water, acidulated or
otherwise.
I make this chamber in two or more parts provided with flanges or any other
means of uniting the parts securely to withstand the required pressure. I provide
in the upper part of the upper chamber, three or more openings, one for supplying
the reservoir with water, and for putting in the materials to generate carbonic acid
gas, another for the insertion of a spindle to carry revolving agitators and the third
for fitting a suitable safety valve and pressure gauge.
In the bottom of the lower chamber I provide an opening for the passage of a
draw-off pipe, which I pass upwards through a dividing plate into the upper
chamber, in such a manner as not to interfere with the rotating of the blades or
agitators, which I attach to a spindle passing through the upper and lower
chambers.
The agitators in the lower chambers are so constructed as to thoroughly agitate
the materials used for generating gas.
Through the plate above mentioned, which divides the upper and lower chambers,
I pass another tube of suitable dimensions to convey into the lower chamber the
materials used for generating gas.
The upper end of this pipe opens about an inch below the openings in the top of
the upper chamber, so that by means of funnels, the one aperture can be used for
conveying materials into the lower chamber or for supplying the upper chamber
with water or other liquid.
The draw-off pipe on passing out of the bottom of the lower reservoir is
constructed to communicate with a number of pipes corresponding to and opening
into an equal number of vertical tubes arranged to resemble architectural columns
or otherwise outside and round the reservoir.
The interior of each of these columns is divided into two chambers, the upper
chamber for storage of syrups, mineral salts, essences &c., and the lower chamber
for receiving aërated water or other liquid from the central reservoir.
From the lower end of each column a pipe and a draw-off tap is provided
connected with a smaller pipe, which opens into the syrup chamber, and supplies
the aërated water with the exact proportion of syrup &c., &c., required.
Each of these draw-off taps is constructed to make an electrical contact which
completes the circuit of a battery operating an electro-motor which I attach to the
outside of the upper part of the central reservoir and connect to the spindle which
passes through the two chambers of the said reservoir and carries the blades or
agitators..
By this means violent agitation is set up on turning the tap to draw off the
aërated beverages.
In the accompanying drawings-
Fig. 1 is a sectional elevation of the apparatus.
A is a cylinder or reservoir of any suitable material or shape to contain the
liquid or liquids required to be aerated. B is the agitator fixed upon the spindle C.
D is another smaller agitator also fitted on the bottom part of the above named
spindle C, which passes from the upper to the lower chambers E & F, through the

page_text: dividing plate G, the end of the spindle C, takes its bearing upon a centre or
seating at the bottom of the chamber F, the top end of the spindle C, passing also
through the centre of the top part, of the cylinder A, into what I call the electrical
chamber H in which I have a suitable motor V put in operation by means of a
switch or any suitable connection which I connect to the key of the draw-off tap or
taps R. The agitators B are set in motion by the electric motor and revolve at
great speed. The lower chamber F is constructed to contain carbonic acid gas,
and by the motion of the agitators both of the upper and lower chambers the liquids
and carbonic acid gas are thoroughly agitated simultaneously. K is a tube of any
suitable material fixed in the interior of the cylinder A, passing through the
dividing plate G into the lower chamber F for the supplying of materials for
generating carbonic acid gas. N is a vertical tube or column divided into
chambers O&P, the upper chamber O is constructed to contain fruit, essences,
syrups, mineral salts or tonic preparations, at the bottom of this chamber I insert a
small tube Q fitted with a regulating valve to regulate the required quantity of
essence or syrups. The lower end of this tube Q I connect into the draw-off
tap R.
The lower chamber P is also constructed to contain aerated liquid which is
supplied from the cylinder A.
From the bottom of the chamber P I insert a tube S of any suitable dimensions
and connect the lower end of this tube also into the draw-off tap R so that the one
turning of the tap discharges aerated liquid and essence or syrup simultaneously.
Having thus described the nature of my said invention and the manner in which
it may be carried into effect, I also wish it to be understood that I do not confine
myself to the exact details of mode of construction herein described reserving the
right to modify, but what I claim as my invention and desire to be secured by the
herein before part recited Letters Patent is :-
1. The combination substantially as described.
2. The application of electricity as described in the manufacture of aerated
beverages.
3. The small storage chambers connected with a main generating reservoir with
syrup cups above and pipes as arranged.
