PROVISIONAL SPECIFICATION.
Improvements in Means or Apparatus for Charging Liquids with
Gases.
I, VICTOR ERNEST JULES DURAFORT, fils, of 162, Boulevard Voltaire, Paris, in
the Republic of France, Engineer, do hereby declare the nature of my invention
to be as follows:-
This invention relates to means or apparatus for charging liquids with gases
and is especially applicable to the charging of water in bottles or gasogenes with
carbonic acid gas in which connection I will describe it as from this its general
nature and application will be understood.
According to my invention I provide a reservoir of steel or the like, having
screwed on its upper end a cap for allowing the introduction of a steel capsule,
provided with a valve and containing the compressed or liquified carbonic acid.
The said capsule is placed in a carrier, a screw rod passes through the cap
and is provided with a milled head or other means for turning it its lower end
bearing on a diaphragm the underside of which comes against the aforesaid valve
of the capsule so that by turning said rod the valve can be opened and the gas
be liberated from the capsule to pass through perforations in the carrier and
thence into the reservoir which is provided at its lower end with a regulator for
controlling the pressure of the gas. This may be of any suitable kind for
example the gas may pass by passages to an inner chamber where it exerts
pressure on a diaphragm so as to act on a differential piston which bears against
a second diaphragm.
If the pressure transmitted by the piston be greater than the resistance of a
spring which may be adjusted for any desired pressure and acts upon a valve,
the said valve is raised and blocks the orifice of the passage by which the gas
enters. A cock closes the exit orifice for the gas, adjacent to which a safety
valve is provided.
A strong tube connects the reservoir to the bottle or syphon, which latter is
provided with a plug which can be secured thereon or therein and is provided
with a small valve closed by a spring. The said plug carries at its upper part
a resilient ring inserted in a screw block and it has a groove for receiving the
side lugs of a cap piece in which is a sleeve terminating in a seating which a
spring keeps against the aforesaid resilient ring. The said sleeve and the lower
end of the reservoir for gas are provided with means for attaching the connecting
tube.
When it is desired to saturate the liquid in a bottle or syphon with gas a
capsule containing the gas is placed in the carrier contained in the reservoir, the
cap is screwed on and then by forcing down the screw rod the gas is liberated
from the capsule and passes out into the reservoir. The liquid to be gasified is
put in the bottle or syphon. the cap is secured to the plug in the neck of the
bottle or syphon and the tube is connected and the cock leading from the base

page_text: of the reservoir is opened. The gas passes through the tube from the reservoir
and entering the bottle or syphon is absorbed by the liquid. In the case of a
bottle it should be held upside down but with a syphon the gas passes down into
the liquid by the ordinary tube to which it is led by a, channel leading down
from the special cap or head piece. The bottle or syphon should then be sharply
shaken.
The gas contained in the reservoir is thus withdrawn in succession until the
liquid in the bottle or syphon is sufficiently charged with gas.

Improvements in Means or Apparatus for Charging Liquids with
Gases,
I, VICTOR ERNEST JULES DURAFORT, fils, of 162, Boulevard Voltaire, Paris, in
the Republic of France, 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:-
This invention relates to means or apparatus for charging liquids with gases
and is especially applicable to the charging of water in bottles or gasogenes with
carbonic acid gas in which connection I will describe it as from this its general
nature and application will be understood.
I will describe the invention referring to the accompanying drawings. Figure 1
shews in vertical section my invention applied to a bottle. and Figure 2 shews
the invention in elevation partly in section applied to a syphon.
According to my invention I provide a reservoir 1 of steel or the like having
screwed on its upper end a removeable cap 2 for allowing the introduction of a
steel capsule 3 provided with a valve 4 and containing the compressed or liquified
carbonic acid.
The said capsule is placed in a carrier 5. A screw rod 6 passes through the
cap 2 and is provided with a milled head 7 or other means for turning it, its lower
end bearing on a diaphragm 8, the underside of which comes against the afore-
said valve 4 of the capsule, so that by turning the said rod the valve can be
opened and the gas be liberated from the capsule to pass through perforations 5*
in the carrier and thence into the said reservoir 1 which is provided at its lower
end with a regulator for controlling the pressure of the gas. This may be of
any suitable kind. In the arrangement shewn for example in the drawing, the
gas passes by passages 9 and 10 to an inner chamber 11, where it exerts pressure
on a diaphragm 12 so as to act on a differential piston 13 which bears against a
second diaphragm 14.
If the pressure transmitted by the piston 13 be greater than the resistance of
a spring 15 which may be adjusted for any desired pressure and acts upon a
valve 16, the said valve is raised and blocks the orifice 17 of the passage 9 by
which the gas enters. A cock 18. closes the exit orifice for the gas, adjacent to
which a safety valve 19 is provided.
A strong tube 20 connects the reservoir 1 to the bottle or syphon, which latter
is provided with a cap or head piece comprising a plug 21 which can be secured
thereon or therein and is provided with a small valve 22 closed by a spring 23.
The said plug 21 carries at its upper part a resilient ring 24 inserted in a screw
block 25 and a groove 26 for receiving the side lugs 27 of a cap piece 28 thus

page_text: making a bayonet joint for example, in which is a sleeve 29 terminating in a
seating 30, which a spring 31 keeps against the aforesaid resilient ring 24. The
said sleeve and the lower end of the reservoir for gas are provided with means
for attaching the connecting tube.
When it is desired to saturate the liquid in a bottle or syphon with gas a
capsule 3 containing the gas is placed in the carrier 5 contained in the reservoir 1,
the cap 2 is screwed on and then by forcing down the screw rod 6 the gas is
liberated from the capsule and passes out into the reservoir. The liquid to be
gasified is put in the bottle or syphon the cap 28 is secured to the plug 21 in
the neck of the bottle or syphon and the tube is connected and the cock 18 leading
from the base of the reservoir is opened.
The gas passes through the tube 20 from the reservoir and entering the bottle
or syphon by the valve 22 is absorbed by the liquid. In the case of a bottle,
it should be held upside down but with a syphon the gas passes down into the
liquid by the ordinary tube 33 to which it is led by a channel 32 leading down
from the aforesaid cap or head piece. The bottle or syphon should then be sharply
shaken. The gas contained in the reservoir is thus withdrawn in succession until
the liquid in the bottle or syphon is sufficiently charged with gas.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. Apparatus for charging liquids with gases comprising a reservoir for pro-
viding compressed or liquified gas at a predetermined pressure contained in a
capsule, and a cap or head piece connected to the said reservoir by a tube for
obtaining the absorption of the gas from the reservoir by the liquid contained
in the bottle or syphon substantially as hereinbefore described.
2. In apparatus as claimed in the preceding claiming clause, a reservoir for
supplying gas at a predetermined pressure provided at its upper end with a carrier
for a capsule, and at its lower end with a regulator for controlling the pressure
of the gas with a safety valve and exit cock, the cap of the reservoir being pro-
vided with a screw rod for opening, by the application of pressure on a diaphragm,
the valve of the capsule, substantially as hereinbefore described and illustrated
in the accompanying drawings.
3. In apparatus as claimed in the first claiming clause, a head piece for the
bottle or syphon, comprising a plug, provided with a spring valve and a cap
connected thereto a spring in the said cap acting on a sleeve having a seating
which the spring keeps against a resilient ring fixed in the plug substantially as
herein before described and shewn in the accompanying drawings.
