I FREDERICK FOSTER of Niagara Works Eagle Wharf Road Hoxton in the County
of Middlesex Engineer do hereby declare the nature of this invention to be as
follows:
This invention relates to a modification of the machine the subject of Letters
Patent granted to me dated 23rd May 1882 and numbered 2426.
According to this invention I provide a condenser mounted on a frame at the base
of which on one side is fitted a rotary pump for elevating the liquid to be aërated.
On the opposite side is an attachment capable of receiving a portable iron vessel
containing compressed carbonic acid gas and at an intermediate point a band wheel
fitted with a handle for driving turns upon a stud and communicates motion by means
of a band to the fan with which the liquid within the condenser may be agitated as
required. By the use of the portable vessels containing compressed carbonic acid
gas I am able to dispense with all those parts of the patented machine referred to
which are required for generating and storing the gas and for delivering the gas in
a compressed form to the condenser containing the liquid to be aërated and I am
enabled to dispel the atmospheric air by first charging the liquid with gas and then
reducing the pressure by allowing some of the gas to escape carrying with it the
atmospheric air. I then charge the liquid with gas to the required bottling pressure.
Hitherto I have withdrawn the air by means of a pump before charging the liquid
with carbonic acid gas. The whole of the operations required for the aërating process
are controlled by the rotary pump, the hand wheel and an arrangement of cocks all
placed at a convenient height for easy manipulation while the condenser is mounted
at such a height as to increase the rate of flow for the liquid to the bottling machine
on the gravitation arrangement described in my former specification of Patent above

page_text: In order to utilise the carbonic acid gas left in the condenser when the liquid has
been withdrawn for bottling I set the agitator in motion while a fresh charge of
liquid is being pumped into the condenser. By this means the surplus gas remain-
ing in the condenser is partly absorbed by the fresh charge of liquid introduced.
The compressed carbonic acid gas may be fed to the condenser by turning on the
outlet cock from the portable iron vessel containing the gas, at intervals as required
to maintain the required pressure for bottling at a uniform pressure. Or this object
may be more accurately attained by fitting the portable iron vessel with a pressure
reducing valve by means of which any required pressure in the condenser may be
maintained automatically.

page_text: I FREDERICK FOSTER of Niagara Works Eagle Wharf Road Hoxton in the
County of Middlesex Engineer do hereby declare the nature of this invention and in
what manner the same is to be perforined, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a modification of the machine the subject of Letters
Patent granted to me dated 23 May 1882 and numbered 2426.
According to this invention I provide a condenser mounted on a frame at the
base of which is an attachment capable of receiving a portable iron vossol containing
compressed carbonic acid gas and at an intermediate point a band wheel fitted with a
handle for driving turns upon a stud and communicates motion by means of a band
to the fan with which the liquid within the condenser may be agitated as required.
By the use of the portable vessels containing compressed carbonic acid gas I am
able to dispense with all those parts of the patented machine referred to which are
required for generating and storing the gas and for delivering the gas in a com-
pressed form to the condenser containing the liquid to be aërated and I am enabled
to dispel the atmospheric air by first charging the liquid with gas and then reducing
the pressure by allowing some of the gas to escape carrying with it the atmospheric
air. I then charge the liquid with gas to the required bottling pressure. Hitherto I
have withdrawn the air by means of a pump before charging the liquid with carbonic
acid gas.
The whole of the operations required for the aërating process are controlled by a
rotary pump, (which may be of the usual form employed as racking pumps) the hand
wheel for operating the agitator, and an arrangement of cocks all placed at a
convenient height for easy manipulation while the condenser is mounted at such a
height as to increase the rate of flow for the liquid to the bottling machine on the
gravitation arrangement described in my former Specification of Patent above
referred to.
In order to utilise the carbonic acid gas left in the condenser when the liquid has
been withdrawn for bottling I set the agitator in motion while a fresh charge of
liquid is being pumped into the condenser. By this means the surplus gas remaining
in the condenser is partly absorbed by the fresh charge of liquid introduced.
The compressed carbonic acid gas may be fed to the condenser by turning on the
outlet cock from the portable iron vessel containing the gas at intervals as required to
maintain the required pressure for bottling. Or this object may be more accurately

of which any required pressure in the condenser may be maintained automatically.
In the accompanying drawing A represents the condenser B B the attachment for
receiving the portable iron vessel containing compressed carbonic acid gas. O is the
hand wheel by means of which the agitator D is put in motion when required.
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
The process of aerating liquids substantially as herein before described by means of
the combination of parts constituting the machine as herein before described and
illustrated by the accompanying drawing.
