HERBERT WILLIAM PAYNE of Severn Street Birmingham in the County of
Warwick 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 relates to aerating machines commonly known as Soda Water
machines and it consists in Improvements in attachments to the Aerated water
cylinder or condenser in which the liquid to be aerated is caused to absorb carbonic
acid gas under pressure. In some machines of existing construction there is a
difficulty in getting the liquid to absorb the gas at a sufficiently rapid rate and even
where a mechanical agitator is used, if it is run too slowly or as sometimes happens
allowed to stop altogether, the liquid run off from the condensing cylinder is poor in
quality and indifferently aerated.
'
The object of my present invention is to alter the arrangements of such cylinders
so that the aeration may be more rapid and efficient even when the mechanical
agitator or stirrer is at rest. In machines as commonly constructed the compressing
pump driven from a crank shaft takes in a charge of liquid and carbonic acid gas and
compresses this charge through valves into a cylinder. In carrying out my invention
I place between the compressing pump and the condensing cylinder a small chamber
constructed in the following manner. The chamber is metallic and is a vertical
cylinder, the pipe leading from the compressing pump enters below and forms a spiral
coil or screw within the chamber. The end of the spiral coil is stopped up and the
mixture of liquid and gas from the pump is forced through a number of small
perforations in it. A horizontal diaphram about the middle, divides the chamber into
two portions and a pipe projects through this diaphram a certain depth in the lower
part of the chamber.
⚫near
The pipe continues above the diaphram and forms a spiral coil similar to the lower
one having perforations in its surface. The exit pipe passes through the upper part
of the chamber terminating within the upper half of the chainber in a position.
the diaphram and connecting at its other extremity to the condensing cylinder. When
the mixture of liquid and gas is forced in below it dashes through the perforations in

page_text: small jets and is thoroughly broken up against the sides of the chamber in spray. As
the end of the upper spiral coil dips considerably into the lower half of the chamber
a portion of the chamber is always filled above the level of the liquid with carbonic
acid gas and the liquid and gas passing from the perforations pass not through liquid
but through an atmosphere of carbonic acid.
In the same way the liquid and gas passes from the lower half of the upper half of
the chamber which also contains a gaseous atmosphere. By means of this arrange-
ment the liquid before entering the main condensing cylinder at all has absorbed a
considerable amount of carbonic acid and by attaching such a chamber to a machine
which is acting badly I improve it very considerably. I sometimes arrange the main
condensing cylinder with a horizontal diaphram separating it into two parts. A pipe
passes through it terminating at a level conveniently near the upper end of the
cylinder; this pipe leads to a space formed under the diaphram between it and a
perforated metal sheet. The action is as follows:-The liquid after entering from the
compressing pump and the intermediate chamber must fill up to the level of the top
of the pipe before discharging from the upper part of the cylinder; when it does
overflow it passes to the lower half through the perforated plate in a series of small
streams. In drawing off from the lower half the level is arranged so that these
streams fall through a considerable atmosphere of carbonic acid and thereby complete
the saturation.
In order that my invention and the manner of performing it may be understood I
hereunto append a sheet of explanatory drawings.
Figure 1 is a vertical section showing my invention in detail.
Figure 2 is a general arrangement showing its application to an existing
machine.
A is the intermediate chamber divided by the diaphram B, the inlet pipe C from
the pump terminates in a spiral D having small perforations as shown. A similar
spiral E occupies the upper half of the chamber A and the pipe K feeding it passes
down as shown towards the bottem of the lower half of the chamber. The pipe F
also dipping into the liquid by the portion L as shown carries it off to the cylinder G
divided by the diaphram H into two parts. The pipe 1 passes through this diaphram
and leads into the space above the perforated metal plate J leading to the lower
part G of the cylinder G. The action is as follows:-
The compressing pump forces the mixed liquid and carbonic acid gas through C
into the spiral D from which it is discharged through perforations of convenient
number and area into the lower part of A.
As the liquid is always taken off at a point low down in the chamber as shown in
Figure 1 a constant atmosphere of carbonic acid gas is maintained through which the
entering jets strike and are broken up into spray against the walls. The liquid is
then forced through the pipe K and discharged at the perforations in the spiral E
where the same process occurs as in the lower half; it then passes by the pipe L
into F and thence to the cylinder G where the liquid fills up to the end of the pipe I,
that is M and then is forced through that pipe to the space above the perforated plate J
from which it flows through an atmosphere of carbonic acid to the liquid in G¹ and
from G¹ it is drawn off as required for bottling.
I have described the intermediate chamber A as divided into two portions by the
diaphram.B but the two portions may be made as separate vessels, and it
may also
be divided into more than two parts in each of which the arrangements for injection
and spraying are similar to what I have herein before described and more than two
vessels might be used.
Suitable pressure gauges of ordinary construction are used to determine the pressure
within the vessel, and the ordinary safety valve arrangements are attached.
Figure 2 is similar to figure 1 and the same parts are similarly lettered.
It shows
a glass gauge N which indicates the height of liquid within the apparatus. The
discharge from the vessel takes place at O by outlets of any convenient number and
arrangement. Some parts of figure 2 are not lettered but they are common to
machines of ordinary construction and are readily understood.

page_text: The pipe I may forminate at the upper level without the bead shown in the
drawings but I prefer to construct it in the manner described. By constructing
an aerating machine with the improvements described the rapidity of the absorbtion
of gas is greatly increased and a better aerated water is produced.
The glass gauge N is supplied with a three way tap P so that when in one position
the level of the liquid in the lower part G is indicated while in another position the
level in the upper is shown and on a third position the liquid in the top portion may
be run into the lower part. G¹ to empty the cylinder completely when finishing a days
work or for any other purpose. I prefer to empty in this way but other arrangements
may be adopted.
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 :-
:-
1. The cylinder A divided into two or more parts by a horizontal diaphram or
diaphrams arranged with perforated pipes D and E and their dip pipes H and L
substantially as and for the purpose herein before described.
2. The improved arrangement of cylinder G with a diaphram H, a pipe I and the
perforated plate J substantially as and for the purpose hereinbefore described.
3. The combination of the cylinder A with cylinder G and pipe 1 leading through
a diaphram H to a perforated plate J substantially as and for the purpose hereinbefore
described.
