Improved Method of and Apparatus for Aerating Liquids and
Bottling same.
I JOHN MALCOLM MACDONALD of 12, Hillside Wimbledon in the County of
Surrey Engineer do hereby declare the nature of this invention to be as follows:-
The object of this invention is a method of and apparatus for aerating and
bottling liquids at one operation and at the same time keeping up the supply of the
liquid to be aerated and dispensing with the use of a pump and snifter or their
equivalents such liquids being aerated by means of compressed gases.
It is well known by ordinary methods the bottle used to contain aerated liquids
at the moment of filling is full of atmospheric air and therefore it has been necessary
to employ a device called a snifter to allow the escape of this air when it has
become so compressed in the bottle by the pressure of the aerated water and. the
gas in the process of bottling as not to allow any more water to enter until it is
allowed to escape by means of the snifter aforesaid. It is also well known that by
actuating the snifter not only is the air allowed to escape but also a large proportion
of the gas, and thus not only is the gas wasted but the pressure that should remain
in the bottle is lowered. It is therefore obvious if bottles could be charged without
containing any atmospheric air that a highly carbonated water could be produced
at a much lower pressure thus effecting a great economy in gas and bottles.
I therefore according to one part of this invention get rid of the atmospheric
air in the bottles by filling the said bottles in the first instance with the liquid to be
aerated which liquid is discharged into the saturator and saturated with gas and
returned to the bottle fully aerated without either gas or the liquid to be impregnated
therewith coming into contact with atmospheric air at all.
A convenient method of carrying out this invention is by means of an apparatus
I constructed substantially as follows:-
I construct a cylindrical vessel of copper and gun metal or of other suitable
materials fitted with trunnions rotating in suitable bearings. This vessel I.call the
saturator.
I
On the circumference of the saturator I place one or more valve or .valves.
(though I prefer never to use less than two valves) each communicating with a
bottling apparatus arranged to fill either stoppered or corked bottles or suitable
syphons. When more than one valve bottle and bottling apparatus are used. these
valves and bottling apparatus radiate from the centre of the saturator and are
constructed as follows for stoppered bottles such as those known as "codds."
attach to each valve a nozzle fitted with indiarubber or other suitable washer
against which the neck of the bottle is pressed by means of a suitable bottle holding
device the valves being so arranged that the liquid to be aerated is discharged when
the bottle is at the top of the machine and the aerated liquid is admitted to each
bottle when it arrives on rotation of the saturator at the point where the liquid by
its gravity will flow into the bottle. Each valve is fitted with suitable mechanism
to lift the ball to allow the liquid from the bottle to freely enter the saturator when
required.
The interior of the saturator is so arranged in compartments comprising a number
of perforated diaphragms through which the liquid to be aerated passes in a finely
divided state (so as to present the greatest surface of liquid to the action of the
gas) to the bottom of the saturator ready for filling into the bottle.
The gas to aerate the liquid is admitted to the container from the gas tube or
bottle by means of a pipe connected to one of the trunnions on which the container

be mounted a suitable gas regulator to control the pressure of the gas supplied to
the saturator.

COMPLETE SPECIFICATION.
Improved Method of and Apparatus for Aerating Liquids and
Bottling same.
I, JOHN MALCOLM MACDONALD of Wimbledon in the County of Surrey
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 :-
The object of this invention is a method of and apparatus for aerating and
bottling liquids at one operation and at the same time keeping up the supply of the
liquid to be aerated and dispensing with the use of a pump and snifter or their
equivalents such liquids being aerated by means of compressed gases.
It is well known by ordinary methods the bottle used to contain aerated liquids
at the moment of filling is full of atmospheric air and therefore it has been necessary
to employ a device called a snifter to allow the escape of this air when it has
become so compressed in the bottle by the pressure of the aerated water and the
gas in the process of bottling as not to allow any more water to enter until it is
allowed to escape by means of the snifter aforesaid." It is also well known that by
actuating the snifter not only is the air allowed to escape but also a large proportion
of gas, and thus not only is the gas wasted but the pressure that should remain in
the bottle is lowered. It is therefore obvious if bottles could be charged without
containing any atmospheric air that a highly carbonated water could be produced
at a much lower pressure thus effecting a great economy in gas and bottles. I
therefore according to one part of this invention get rid of the atmospheric air in
the bottles by filling the said bottles in the first instance with liquid to be aerated,
which liquid is discharged into the saturator and saturated with gas and returned
to the bottle fully aerated without either gas or the liquid to be impregnated
therewith coming into contact with atmospheric air at all.
A convenient method of carrying out this invention is by means of an apparatus
constructed substantially as follows:-1 construct a cylindrical vessel of copper or
gun metal or of other suitable materials fitted with trunnions rotating in suitable
bearings, this vessel I call the saturator, on the circumference of the saturator I
place one or more valve or valves (though I prefer never to use less than two
valves) each communicating with a bottling apparatus arranged to fill cither
stoppered or corked bottles, or suitable syphons.
When more than one valve bottle and bottling apparatus are used these valves
and bottling apparatus radiate from the centre of the saturator and are constructed
as follows for stoppered bottles such as those known as codds " I attach to each
valve a nozzle fitted with indiarubber or other suitable washer against which the
neck of the bottle is pressed by means of a suitable bottle holding device the valves
being so arranged that the liquid to be aerated is discharged when the bottle is at
the top of the machine and the aerated liquid is admitted to each bottle when it
arrives on rotation of the saturator at the point where the liquid by its gravity will
flow into the bottle. Each valve is fitted with suitable mechanism to lift the ball
to allow the liquid from the bottle to freely enter the saturator when required.
The interior of the saturator is so arranged in compartments comprising a number
of perforated diaphragms through which the liquid to be aerated passes in a finely
divided state (so as to present the greatest surface of liquid to the action of the
gas) to the bottom of the saturator ready for filling into the bottle.

page_text: The gas to aerate the liquid is admitted to the container from the gas tube or
bottle by means of a pipe connected to one of the trunnions on which the container
rotates such trunnion being made hollow for this purpose, and on this pipe may be
mounted a suitable gas regulator to control the pressure of the gas supplied to the
saturator.
And in order that my said invention may be better understood I will proceed to
explain the same with reference to the accompanying sheet of drawings in which
a is the cylinder of copper or other suitable material containing one or more
longitudinal diaphragms (not shewn) the cylinder a is provided with dished
ends b. b. of gun metal or other suitable material provided with trunnions c. c
rotating in bearings el e' in the standards f. f' :-g. is the bed plate:-h. h. tubes of
compressed gas: i clip for supporting same: k. gas inlet pipe: 7. pressure gauge:

means of the spring t.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is:
The hereinbefore described improved method of and apparatus for aerating
liquids and bottling the same by first filling the bottles to be used in such bottling
process with the liquid to be aerated then allowing such liquid to enter the apparatus
to be acrated and subsequently causing the liquid when so acrated to return to the
bottles all substantially as described and represented in the drawing.
