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 inven-
tion to be as follows:-
:-
This invention consists in apparatus enabling liquids contained in syphon bottles,
and other like receptacles, to be charged with carbonic acid or other gas, without
the aid of special installations, by means of small tubes or cartridges filled with com-
pressed or liquefied carbonic acid, or other gas, which is to be dissolved in the liquid
to be gasified or aërated.
The characteristic of the apparatus is the facility with which the small recipient
or cartridge can be replaced, when empty.
According to this invention, the head of the syphon bottle, or the like, is pro-
vided with a metallic tube or chamber, which is open at its upper end and may be
prolonged at its lower end so as to dip into the water, or other liquid, contained in
the syphon; and into this tube or chamber the holder or cartridge containing the
compressed or liquefied gas is placed, said holder or cartridge being of such a size
as to leave a space between itself and the interior of the tube or chamber.
The holder or cartridge consists of a strong tube furnished with a ball, or other
suitable, valve which is kept normally closed by the internal pressure of the
compressed or liquefied gas contained in the said cartridge.
This holder or cartridge is placed within the before mentioned tube or chamber,
through an opening formed in the head of the syphon which is hermetically closed
by a screwed cover or stopper. Through this cover or stopper passes a headed
screw which terminates just above the valve of the cartridge, so that by operating said
screw the valve is opened and the compressed or liquefied gas is allowed to gradually
escape from the cartridge and to enter the liquid in the syphon, and which liquid
when saturated with the gas can be drawn off through a tube communicating with
the tap or cock of the syphon-bottle, or the like.
When the cartridge is empty, it is only necessary to unscrew the cover or stopper,
on the head of the syphon bottle, then remove the cartridge and insert a fresh one
in its place.
Instead of the tube or chamber extending into the liquid, it may be located in a
globular chamber arranged at the upper part of the head of the syphon, and said
chamber be provided with a passage or conduit leading into the bottle, and through
this passage or conduit the gas passes into the liquid to be saturated.

Improvements in Seltzogenes and like Apparatus.
I, ERNEST DE PASS, of 78, Fleet Street, in the City of London, Fellow of
10 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

page_text: is to say :-
This invention consists in apparatus enabling liquids contained in syphon bottles,
and other like receptacles, to be charged with carbonic acid or other gas, without
the aid of special installations, by means of small tubes or cartridges filled with
compressed or liquefied carbonic acid or other gas, which is to be dissolved in the
liquid to be gasified or aërated.
:
The characteristic of the apparatus is the facility with which the small recipient
or cartridge, when empty, can be replaced by a filled one.
According to this invention, the head of the syphon bottle, or the like, is provided
with a metallic tube or chamber which is open at its upper end and may be pro-
longed at its lower end, so as to dip into the water, or other liquid, contained in the
syphon; and into this tube or chamber the holder or cartridge, containing the
compressed or liquefied gas, is placed, said holder or cartridge being of such a size
as to leave a space between itself and the interior of the tube or chamber.
The holder or cartridge consists of a strong tube furnished with a ball or other
suitable valve, which is kept normally closed by the internal pressure of the
compressed or liquefied gas contained in the said cartridge.
This holder or cartridge is placed within the before mentioned tube or chamber
through an opening formed in the head of the syphon which is hermetically closed
by a screwed cover or stopper. Through this cover or stopper passes a headed
screw which terminates just above the valve of the cartridge, so that by operating
said screw the valve is opened and the compressed or liquefied gas is allowed to
gradually escape from the cartridge and to enter the liquid in the syphon, and
which liquid, when saturated with the gas, can be drawn off through a tube com-
municating with the tap or cock of the syphon bottle, or the like.
When the cartridge is empty it is only necessary to unscrew the cover or stopper
on the head of the syphon bottle, then remove the cartridge and insert a fresh one
in its place.
And in order that the invention may be readily understood I will proceed to
describe the same fully with reference to the annexed drawings.
Referring to Fig. 1, the apparatus here shown in vertical section, through its
axis, represents a syphon head, which is fixed upon the neck of a thick glass or other
receptacle 2, by being screwed to an inner or fixed ring 3, 3, formed in two parts
and having a rubber washer 4 interposed to ensure tightness. This is a usual mode
of fixing, upon which the invention does not bear, but is ouly mentioned by way of
example, as any other suitable means for the same purpose may be employed.
1 is the bead of the syphon which is provided with a tap or cock 5, for drawing
off the gaseous liquid which has been forced, by pressure, into a tube 6, said tube
being connected at its lower part to a glass tube 7. This arrangement is thus
firmly secured to the syphon bottle or vessel 2, which is filled with liquid by
unscrewing the screw cap or stopper 8 which is furnished with an elastic
washer 9.
Into this cap or stopper is screwed a metal tube 10, terminating at bottom in a
dip tube 11. In the tube 10 is located the cartridge or gas receptacle, sufficient
space being left to allow free passage to the gas, for instance, compressed or liquefied
carbonic acid gas.
:
The cartridge consists of a strong metal tube 12, closed at its lower end, and
provided at its upper with a narrow orifice which is kept closed by a ball 13, or
by any suitable valve which is kept applied against its seat by the internal pressure.
The closing of this cartridge is therefore the more airtight as the pressure of the
compressed or liquefied gas is the stronger.
Above the orifice of the tube 12 is arranged a screw threaded rod 14 which can
be raised, or lowered, by turning the milled button 15. The screwed portion of
this rod traverses a nut 16 which compresses a rubber sleeve 17 through which the
rod passes tight and easy. All issue is therefore closed to the gas, whatever may
be the position of the rod.

page_text: This apparatus works as follows:-It being supposed, for instance, to be applied
to the manufacture of seltzer water.
The bottle being filled with water up to the height of the glass tube 11, and the
receptacle 12 with liquid carbonic acid, the milled button 15 is turned in the
required. direction so as to cause the rod or valve 14 to descend. This latter
slightly pushes down the ball 13 and allows the carbonic acid gas, which fills the
tube 10, as well as the tube 11, to escape gradually and to pass out through the
lower orifice of this tube so as to bubble up into the water where it is immediately
dissolved. The gas then escapes moderately from the cartridge wherein it is
compressed, and without shock. In this way, by being able to regulate the escape
of the gas, any danger which may arise from a too sudden opening of the cartridge
is avoided. If needed, the syphon may be shaken to hasten the saturation and it will
be sufficient to gradually open the tap 5 to allow the gaseous liquid to flow out of
the apparatus.
When the apparatus is empty, it is quite easy to renew the operation; this can
be effected by unscrewing the screw-cap or stopper 8, removing it, and also by
unscrewing therefrom the tube 10, into which a fresh cartridge of compressed gas is
introduced. This advantage of being able to readily remove and replace the cartridge
is an essential feature of the invention, as it does not exist in other apparatus as
heretofore constructed.
To reduce the size and weight of the syphon head, the apparatus may also be
constructed as shown in Figs. 2 to 5, in which the same numerals of reference
represent corresponding parts, or perform the same office, as those in Fig. 1.
two
Referring to Fig. 2, this shows, in vertical axial section, an apparatus which is
only a variant in form of that previously described. By arranging the
tubes 11 and 7 concentrically, as shown in the said figure, a syphon head is obtained
which may be adapted to vessels having a smaller or narrow neck, while the height
and the capacity of the liquid carbonic acid cartridge 12, may be increased, and
hence its duration of service.
The ball 13, shown in Fig. 1, may also be replaced by a stem valve designated
by the same numeral as in Fig. 2. For convenience of transport, of the syphons,
by hand, it is advantageous to cast a small handle 18 on the syphon head.
The working of this apparatus is absolutely identical with that previously
described. The gascons carbonic acid which escapes from the cartridge fills the
free space in the tube 10, and enters the water through the tube 11. When the
tap 5 is opened the liquid is forced out by the pressure in the annular space between
the tubes 11 and 7, and flows out after having filled the space 6.
Referring to Figs. 3 to 5, these show respectively in vertical axial sections on
perpendicular planes and in horizontal transverse section on the line A, B, of Fig. 4,
apparatus of this system applied to an ordinary syphon head.
In this case the size of the liquid carbonic acid cartridge 12 is greatly reduced,
so that without increasing excessively the size of the head, the cartridge may be
placed into the spherical space or cylindro-spherical space 10. The gaseous
carbonic acid after having escaped from the cartridge, through the small valve 13,
enters the water in the syphon through the small passage 11 (formed in the metal
of the head at the time of casting) and through the usual glass tube 7 which
likewise allows passage to the gaseous water forced out by pressure, when the
lever 19 is depressed to remove the valve 20 from its seat, against which it is kept
normally pressed by the coiled spring 21 and by the internal pressure of the gas.
This apparatus is used in exactly the same manner as the preceding ones.
When the liquid carbonic acid cartridge is empty, it is only necessary to unscrew
the upper hemisphere of the chamber 10, to withdraw it, and to insert a filled
cartridge.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim :-
An annaratus for the direct saturation of gaseous liquids consisting substantially

page_text: of a syphon head fixed permanently on the bottle and closed at its upper part by a
"screw cap or stopper carrying a tube into which is introduced a removable and
readily replaceable receptacle or cartridge containing compressed or liquified gas
which is to be gradually emitted through an indicator dip tube, by means of a
screw threaded rod fixed in the cap or stopper above the opening of the receptacle
-or gas cartridge.
