Improvements in Seltzogenes and like Apparatus.
I, ERNEST DE PASS, of 78, Fleet Street, in the City of London, Fellow of
the Chartered Institute of Patent Agents, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in seltzogenes and like apparatus, and
has reference more particularly to apparatus of the kind described in the
Specification of former British Letters Patent granted to me, No. 509, dated the
10th January 1893, that is to say, apparatus for the direct aeration of liquids
contained in syphons or other vessels, by means of cartridges of compressed or
liquefied carbonic acid inserted into the syphon heads and opened by suitable
means to allow of the discharge of the gaseous contents into the liquid to be
aerated or gasified.
According to the present invention, the holder or cartridge is made wider, and
not so high as in the said former patent, and the valve is placed at the lower part
thereof. This cartridge rests upon a rubber washer and is covered by a screw
cap, and the opening of the valve is effected by screwing down this cap. In the
outlet passage for the gaseous carbonic acid, is interposed a wire gauze or
perforated iron plate to retard the flow of the gas. The tube for conducting the
gas into the water is of aluminium, and is arranged concentrically within the tube
through which the aerated liquid flows to the tap, this latter tube being held by
an indiarubber ring or washer, in a china or other lining for preventing contact
between the liquid and the metal syphon head. Surrounding these tubes, is a
filling tube of comparatively large diameter, which is secured by an elastic collar
in the fitting which receives the syphon bead proper. The length of this filling
tube is so adjusted that the bottle can only be filled about two thirds, thus leaving
ample space for the gas above the liquid. But instead of a filling tube, the
apparatus may be filled by means of a funnel having a nozzle of the same width as
the aforesaid filling tube.
To avoid too sudden or dangerously rapid disengagement of the gas the cartridge
may be closed at its lower part by a hollow screw plug having a capillary
perforation for the escape of the gas. In the bore of the plug, are arranged two
superposed discs, one of pewter, the other of tinned sheet iron. These rest upon a
pin fixed in a perforated disc at the upper end of the tube through which the gas
enters the liquid. By pressing the cartridge downward the discs allow the gas to
pass. This downward pressure is effected by a screw having a large milled head
and acting, through a plug and interposed washer, on the said cartridge. Too
great forcing down is prevented by a shoulder or ledge on the cartridge abutting
against a corresponding shoulder or ledge in the syphon head; and to avoid
crushing the cartridge the screw for forcing it down is made of such a length as
will only permit of the proper amount of movement.
This invention may he applied for aerating or gasifying liquids in ordinary
bottles, jars, flasks, and other receptacles. To this end, a hollow plug of metal,
earthenware, ebonite, glass, or other suitable material is fixed, after the manner of
an ordinary cork, in the mouth of the vessel. It is held tight by an india rubber-
sleeve, or otherwise, and the syphon head is screwed into it. This head is not

page_text: provided with a draw-off tap, or with tubes entering the liquid, but in other
respects it resembles that last described. The bore of the plug is closed by a
spring controlled valve which opens to allow the gas to pass, but closes to prevent
liquid entering the plug. The gas is liberated by depressing the cartridge as
before, and the liquid is saturated by shaking the vessel. To withdraw the liquid,
the plug and head are removed from the vessel and the liquid is simply poured out
instead of being syphoned off.

Improvements in Seltzogenes and like Apparatus.
I, ERNEST DE PASS, of 78 Fleet Street, in the City of London, Fellow of
the Chartered Institute of Patent Agents, 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, reference being had
to the accompanying drawings and to the letters and figures marked thereon, that
is to say:
This invention relates to improvements in seltzogenes, and like apparatus, and has
reference more particularly to apparatus of the kind described in the Specification
of former British Letters Patent, No. 509, granted to me and dated 10th January
1893, that is to say apparatus for the direct aeration of liquids contained in
syphons, or other vessels, by means of cartridges of compressed or liquefied
carbonic acid inserted into the syphon heads and opened by suitable means to allow
the discharge of the gaseous contents into the liquid to be aerated or gasified.
And in order that said improvements may be readily understood, I will proceed
to describe the same by aid of the accompanying drawings, in which :
Fig. 1 is a vertical section shewing the upper part of a seltzogene having one
form of the improved apparatus applied thereto.
Fig. 2 is also a vertical section shewing a modification in the construction of the
syphon head, and designed to prevent too sudden disengagement of the gas and
danger of bursting the syphon."
Fig. 3 illustrates the application of the invention to the gasification or aeration
of liquids contained in bottles, jars, flasks, and other receptacles having ordinary
necks.
Referring more particularly to the arrangement shewn in Fig. 1, the holder or
cartridge 12 is made wider and not so high as in the said former patent, and the
valve 13 (the stem of which only is shewn in the figure, and which opens inwards)
is placed at the lower part thereof. This cartridge rests upon a rubber washer 20
and is covered or protected by a screw cap 14, the opening of the valve being
effected by screwing down this cap. In the outlet passage for the gaseous carbonic
acid, a wire gauze, or perforated iron plate, 21 is interposed to retard the flow of
the gas. The tube 11 for conducting the gas into the water is of aluminium, and
is arranged concentrically within the tube 7, through which the gasified or aerated
liquid flows to the valve or tap 5, this latter tube being held by an india-rubber
ring or washer 22 in a china or other lining 23, for preventing contact between the
liquid and the metal syphon bead. Surrounding these tubes is a filling tube 24, of
large diameter, which is secured by an elastic collar 25 in the fitting which receives
the syphon head proper. The length of this filling tube is so adjusted that the
bottle can only be filled about two-thirds, the filling being stopped when the
bottom of the tube is reached, thus leaving ample space for the gas above
the liquid.
Instead, however, of employing a filling tube, the apparatus may be filled by
means of a funnel having a nozzle of the same width as the aforesaid filling tube.

page_text: In the arrangement shewn in Fig. 2, the holder or cartridge 12, is closed at its
lower part by a hollow screw plug 121 having a capillary perforation 13 for the
escape of the gas. In the bore of the plug, are arranged two superposed discs 13¹,
one of pewter the other of tinned sheet iron. These rest upon the point of a steel
pin 14, fixed in a perforated disc at the upper end of the tube through which the
gas enters the liquid, but as it can only escape by traversing the extremely small
passage 13, there is no fear of explosion due to a rapid disengagement of gas, no
matter how clumsly the operator may be. By pressing the cartridge downward
on the pin, the discs are perforated, and then by relieving the pressure, the discs
allow the gas to pass. This downward pressure is effected by a screw 15, having
a large milled head and acting through & plug 14, and interposed washer 15' on
the said cartridge. A shoulder or ledge 12" on the cartridge, abutting against a
corresponding shoulder or ledge 1' in the syphon head, prevents the said cartridge
being forced down too far, and the orifice 13 being damaged against the pin 14',
while, to avoid crushing the cartridge, the screw 15 for forcing it down, is made of
such a length as will only permit of the proper amount of movement.
In applying the improvements to aerating or gasifying liquids in bottles, jars,
flasks, and other receptacles having ordinary necks, as shewn in Fig. 3, a hollow
plug 3, of metal, earthenware, ebonite, glass, cork, or other suitable material, is
fixed, after the manner of an ordinary cork, in the mouth of the vessel, being, if
necessary, held tight by an india rubber ring or sleeve 9, or otherwise, and the
syphon head screwed into it. This head is not provided with a draw-off tap, or
with tubes entering the liquid, but in other respects it resembles that last described.
The bore 11 of the plug is closed by a ball valve 13 kept normally on its seat by
a spring 26 which opens to allow the gas to pass, but closes to prevent liquid
entering the plug. The gas is liberated by depressing the cartridge, as before,
and the liquid is saturated by shaking the vessel. To withdraw the liquid, the
plug and head are removed from the vessel and the liquid is simply poured out
instead of being syphoned off.
The same apparatus can be used for several bottles, by placing therein a filled
cartridge; or in case the bottles containing the liquid to be aerated or gasified is
very large, the aeration or gasification can be effected in several successive
operations.
Having now particularly described and ascertained the nature of the inven-
tion and in what manner the same may be performed, I declare that what I
claim is:
1. A seltzogene, or like apparatus, of the kind described, having its holder or
cartridge provided with a valve at the lower part thereof, and having a screw cap,
or a screw, for acting on the upper part of said holder or cartridge, substantially
as described.
2. In a seltzogene of the kind above referred to, the arrangement of a capillary
passage, such as 13, in the valve, to prevent bursting of the syphon owing to too
sudden disengagement of the gas, substantially as described with reference to
Fig. 2 of the drawings.
3. The arrangement for gasifying or aerating liquids contained in bottles, jars,
flasks, and other receptacles having ordinary necks, substantially as described
with reference to Fig. 3 of the drawings.
4. The improvements in seltzogenes and like apparatus, substantially as herein-
before described and as shewn in the accompanying drawings.
