PROVISIONAL SPECIFICATION.
An Improved Form of Carbonator for Aerated Liquids.
ERNEST LENOARD MARLEY, of 3, Haldane Road, Fulham, in the County of Lon-
don, Mineral Water Engineer, and CHARLES WILLIAM CLAYTON, of 131, New
King's Road, Fulham, in the County of London, Brewer, do hereby declare the
nature of this invention to be as follows:
This invention relates to machines or cylinders used in the aeration of liquids
in which the liquor absorbs gas which is supplied under pressure the action' being
assisted by agitating the liquor by means of a rotary or other paddles, such
machines being commonly known as carbonators; and consists in an improved
construction whereby the present waste of gas upon re-charging is prevented and
also economy of space and of material is effected. In carrying out this invention
we provide a means of dividing the cylinder into two parts in any convenient
manner by preferably by means of a plate or plates at or near the middle of its
length. Each chamber thus formed is provided with a separate agitator, and the
liquor pumps and gas connection are branched so that they connect the two parts
of the cylinder and may deliver into either, and the supply to the fillers is also
arranged to be drawn from either of the chambers. The method of procedure is as
follows: When the first chamber has been emptied the remaining gas is allowed
to pass into the second chamber to assist in the first stages of the aeration of the

this arrangement no gas need be wasted in order to re-charge the cylinder and
that with this compact construction a machine is produced which has double the
capacity and which works with greater economy, without much increase of cost
or space occupied.

An Improved Form of Carbonator for Aerated Liquids.
We, ERNEST LENOARD MARLEY, of No. 3, Haldane Road, North End, Fulham,
Mineral Water Engineer, and CHARLES WILLIAM CLAYTON, of No. 131, New King's
Road, Fulham, Mineral 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 :-
-
This invention relates to machines or cylinders used in the aëration of liquids in

page_text: which the liquor absorbs gas such as carbonic acid gas which gas is supplied under
pressure, the action being assisted by agitating the liquor by means of rotary
or other paddles. Machines of this kind are commonly known as carbonators and
our invention consists in so making such machines that the present waste of
gas upon re-charging is prevented and ecenomy of material and of space occupied
are effected.
Figure 1 of the accompanying sheet of drawings represents partly in side
elevation and partly in section an apparatus constructed according to our inven-
tion and
Figure 2 is a plan thereof.
As shewn we provide means such as a strong diaphragm or dividing plate or
wall A in the cylinder to divide the latter into two parts A and B.
The cylinder is mounted on a frame or support of which a suitable construction
is shewn. and each chamber formed in said cylinder. is provided with separate
agitator shafts such as C and D having paddles and handles mounted thereon in
the usual manner of which one paddle marked D¹ is shewn the said shafts running
in bearings in the ends of the cylinder and on each side of the wall A¹ as shewn.
The gas is supplied from gas tubes or cylinders, not shewn, which are supported
for instance in brackets E and F, to a connection G having branches G¹ and G2
leading to the cocks or valves H and H' respectively which again communicate
with safety valves I and I', pressure gauges K and K and the chambers A and B
respectively. There may be if desired pet cocks L and L' to relieve the pressure
in the chambers but they are not always necessary as if from any reason the pres-
sure should become too high in either of or both the chambers the safety valves
may generally be relied upon to relieve the said chamber or chambers of super-
fluous pressure.
The supply of liquor to the cylinders is effected by means of a force pump M,
having a fly-wheel M and a crank handle Me, if to be turned by hand, or with
fast and loose pulleys if to be operated by power.
The force pump M is provided with two delivery branches M³ and M having
valves M and M thereon respectively so as to permit of one chamber being
filled while the other is being emptied. The chamber A is further provided with
an outlet A2 having a valve or cock A for the supply of carbonated liquor by a
pipe N to the fillers. The chamber B is similarly provided with an outlet 133
having a cock or valve B leading to the said pipe N and the latter is provided
with one or more cocks. In the present instance there are four namely N1, N2, N3
and N, two at each end for connecting to the filling or bottling machines. O
and are gauges for shewing the levels of the liquor in the chambers A and B
respectively.
and
or
The method of working the apparatus is as follows:-
When the chamber A has been emptied of aërated or carbonated liquor the
valve A³ to the supply pipe N communicating with the bottling machines is
shut off and the valve B from the other chamber B to the said supply pipe is
opened the gas remaining in the chamber A is allowed to pass into the chamber B
by means of the valve H pipes G¹ and G2 and valve H¹ to assist in the aëration
bottling of the fresh liquor with which the chamber B is supposed to have
been supplied, while the liquor in the chamber A has been drawn off. The gas
valve H is then closed and the chamber A is supplied with liquor by means of
the pump M until it is filled to say about three quarters of its full capacity. The
supply of gas is then cut off from the chamber B by means of the valve H' if it.
has been used to aid in bottling from that chamber and the valve H is opened
so as to permit the access of the gas to the liquor through pipe G from the reservoir
of gas.
The gas is preferably then cut off from the chamber A and the liquor
is agitated by revolving the paddles on the shaft C whereby a great deal of the
gas is absorbed and the pressure lowered. Gas is then again admitted, shut.off,
and the liquor agitated and so on. Finally when the pressure is sufficient after

page_text: the last agitation the liquor having absorbed as much gas as is required it is
not advisable to again agitate it as otherwise liquor such as beer would be in
too frothy a condition to bottle satisfactorily, but more gas is added during the
filling which next takes place to keep the pressure at the point suitable for the
purpose. It will be understood that when the gas is not being used in one
cylinder for carbonating or aërating purposes, it is as required being utilized in
the other cylinder for keeping up the necessary pressure for the filling operations.
When the chamber B has been emptied the chamber A is ready to be connected
up to the apparatus for filling and the chamber B is then charged with liquor and
carbonated or aërated all as described with reference to the chamber A.
It is thus clear that by this method of working no gas need be wasted in order
to recharge a cylinder and that a machine is provided which has practically
double the ordinary capacity, working with greater economy and without greatly
increasing the cost of the apparatus or the space occupied thereby.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we claim
is:-
1. A carbonator for liquids consisting of two chambers, means for independently
supplying the liquor to both the chambers, means for supplying gas to both
chambers independently, means for agitating the contents of both chambers
independently and means for enabling the aërated liquor to be drawn off from
either of the chambers, substantially as set forth.
2. A carbonator for liquids consisting of a pump, two independent chambers
connected to said pump by pipes having valves therein, paddles mounted on shafts
for agitating the contents of the said chambers, pipe connections between the
two chambers and with a gas supply, valves in such pipe connections for admitting
the gas to one or the other of the chambers and for cutting off the supply of
gas to said chambers, outlet pipes for the liquor from the chambers, valves in
such outlet pipes, a pipe connecting both outlet pipes having a valve or valves at
each end for making connection with filling or bottling machines, safety valves
on said chambers and means for ascertaining the pressure of the gas and the
level of the liquor in each chamber substantially as described and shown.
