Improvements in Means for Use in Effecting the Aeration of Liquids
in Bottles, or like Receptacles, and for Retaining the said Liquids
in, and Discharging them from, the said Bottles, or Receptacles.
We, AERATORS LIMITED, of Broad Street Avenue, in the City of London, and
KENNETH SUTHERLAND MURRAY, of 17, Bedford Court Mansions, in the County
of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the class of bottles, or receptacles, for aerated
liquids, commonly known as syphon bottles, or seltzogenes, from which the
aërated liquid is forced, in quantity as required, by the pressure of the gas in the
bottle, or receptacle; and the said invention has for its principal object to
provide improved means whereby the aëration of liquids in such bottles, or
receptacles, can be effected by liberating gas from a capsule, or container, in
which it is confined under pressure; the said capsule, or container, being, with
great facility, placed in, and removed from, a holder carried by the syphon-
head. The draw-off valve, and the holder for the capsule, or container, of com-
pressed gas, and also the means by which it is pierced, or opened, are carried by
a part capable of sliding vertically in the syphon-head, and pressed downwards
by a spring, so that the draw-off valve is normally pressed to its seat but acts
as a safety-valve to relieve excessive pressure in the bottle, or receptacle.
The liquid is aërated by piercing, or opening, the capsule, or container, of
compressed gas, placed in the holder carried by the said sliding part; the gas
passing through passages (and also through a non-return valve if desired), in
the said sliding part, and down a tube. carried by the syphon-head and descend-
ing as usual to near the bottom of the bottle, or receptacle, but preferably having
the opening at its lower end provided with a ball, or other valve which closes
the said opening when the gas passes from the capsule, or container, and down
the said tube, so that the said gas is caused to issue through a small opening or
openings in the said tube, above the valve, in such direction as to facilitate its
absorption by the liquid in the bottle, 01' receptacle; whilst when
the liquid is withdrawn, it lifts the valve and passes freely up the tube and through
the draw-off valve and out at the nozzle.
After the liquid has been aërated, a handle or device can be operated to move the
said sliding part upwards in the syphon-head and open the draw off valve so
that aerated liquid is discharged at the nozzle.
The following are constructions according to my invention. The syphon head
can be secured to the top of the bottle, or receptacle, in the ordinary, or any suit-
able way which will form a good joint. A web is formed across the lower part of
the interior of the syphon-head, and in this web is a hole, around the upper edge
of which a valve seating is formed. Above this web is a cylindrical chamber.
from the lower part of which is carried the spout, through which the aërated
liquid is discharged. Above the said chamber a continuation is formed, closed at

page_text: the top by a cover, and with a gap at one, or both, sides, sufficient to allow of the
passage of the capsule, or container, of compressed gas. In the said chamber and
continuation is placed the aforesaid sliding part the lower portion of which com-
prises a piston, fitting into the said chamber, and with its lower end reduced, and
having, secured, to it, the draw-off valve, containing clastic material to press
against the valve seat. Inside the piston is a web with an opening through it,
and into the space above this is inserted a small block carrying the steel pin, by
means of which the capsule, or container, is pierced. The block is pierced
vertically by holes which communicate with a horizontal passage which com-
municates with the hole in the web in the piston so that the gas discharged from
the capsule, or container passes therethrough, and through the space below the
web, and through an opening in the draw-off valve into the descending tube and
thence into the liquid in the bottle. A flexible seating is provided into which
the neck end of the capsule, or container, fits to prevent the upward escape of gas-
when the said capsule, or container, is pierced. This seating is preferably re-
inforced by a steel thimble. A check valve (pressed upwards by a spring) can
be placed within the space below the web in the piston to prevent the gas, or
aerated liquid from passing upwards through the hole in the said web if the capsule
or container, be removed after aëration. The upper portion of the sliding part
has an opening at one side, or at both sides, to allow of the capsule, or container,
being placed in position, and removed sideways. The said sliding part can be
moved up and down in the syphon head but is prevented from turning therein
which can be effected by making portions of square, or equivalent form. A joint
may be formed between the lower part of the unreduced part of the piston and the
upper part of the valve by inserting an elastic ring in the space between them.
A spring presses upon the top of the sliding part to keep the draw-off valve
normally to its seat, but yet to allow the said draw-off valve to act as a safety-
valve by rising from its seat to allow of escape of gas by the spout, on any undue
rise of pressure in the bottle or receptacle. Through a plain opening in the
cover on the top of the continuation of the cylindrical chamber of the syphon head
a spindle, is passed the bottom portion of which is screwed through an internal
screw in the head of the sliding part so as to bear on the capsule or container
when put in place. The upper end of the spindle has a lever-handle centered to
it by a pin.
At the bottom end of the tube which descends into the bottle or receptacle is
secured a small valve chamber with an opening at bottom, over which a ball, or
other retention, valve seats itself; above this are small holes directed upwards.
The valve closes the first named opening when the pressure is downwards and
causes the gas to pass upwards through the small holes above so that the gas is
ejected very efficiently into the liquid. The valve rises to allow the liquid being
withdrawn to pass freely into the tube.
The action of the apparatus is as follows:-
Liquid having been introduced into the bottle or receptacle to the requisite
level and the syphon-head secured firmly in place, a capsule, or container of
compressed carbonic acid, or other gas is inserted sideways into place above the
piercing pin the draw off valve being held down upon its seating by the pressure
of the spring. The spindle is then rotated and thus screwed down in the head of
the sliding part so as to press the capsule, or container, onto the pin which pierces
the said capsule or container and the gas is discharged therefrom and passes
through the passages into the tube and thence into the liquid in the bottle or
receptacle. The downward movement of the spindle brings the lever-handle
against a bead on the cover at the top of the continuation of the cylindrical
chamber of the syphon head and when it is desired to withdraw aërated liquid
from the bottle or receptacle, the outer end of the said lever handle is pressed down
(the bead acting as a fulcrum therefor) and the sliding part is thus raised and
the draw-off valve lifted from its seat, and aërated liquid is forced up the tube
and escapes past the said valve and through the spout being prevented by the

page_text: retention valve from escaping through the passages above it in the sliding part,
if the capsule, or container, has been removed after aëration.
If a capsule, or container, be used which is provided with a valve to be opened
by pressure instead of by piercing, the pin is without a pointed end. The spindle
carrying the lever handle, instead of passing through a cover, may be screwed
directly into the top of the sliding part, and the spring may act between a flange
plate in the syphon-head, and a flange on the sliding part. Or the sliding part
may be continued up through the aforesaid cover, and the receptacle for the
capsule, or container, of compressed gas, be at top and a cap be screwed down onto
the top of the said part to effect the piercing the pin being in the upper portion
of the sliding part and the opening for the passage of gas being continued through
the prolongation of the said sliding part between the said pin and the retention.
valve. The draw-off lever-handle in this case is forked so that the prongs of the
fork lie on each side of the sliding part and when the outer end of the said
lever is depressed lift it by bearing on a flange on the sliding part, rounded pro-
jections on the forks of the lever handle engaging in recesses in the 'cover so
as to act as fulera.
The retention valve may be in a chamber above the lever handle instead of in
a lower chamber and instead of the part carrying the spout being secured directly
to the bottle, or receptacle, it can be secured to a shell or casing which is secured
to the bottle or receptacle there being sufficient space between the part carrying
the spout and the shell or casing to allow of liquid introduced by the inlet open-
ing passing into the bottle or receptacle so that liquid can be introduced without
moving the syphon head or any part except a screw cap which closes the inlet
opening the said cap having a leather or other joint to give a tight closure. The
said inlet may be directed upwards for filling whilst the bottle or receptacle is
standing on its base but in order to insure that the bottle or receptacle shall
only be filled to the requisite level the said inlet may be directed out horizontally,
so that the bottle, or receptacle, is placed on its side to be filled and the liquid
will overflow at the inlet when the requisite quantity has been introduced.
The part which carries the capsule or container and the perforating device may
be made separable so that on being removed it can be used for charging any
number of bottles or containers. The part for carrying the capsule or container
and the perforating device when the liquid in the bottle or receptacle is to be
charged with gas is screwed on and when charging has been effected the said part
is removed and a duct cap is screwed on in its place.

Improvements in Means for Use in Effecting the Aeration of Liquids
in Bottles, or like Receptacles, and for Retaining the said Liquids
in, and Discharging them from, the said Bottles, or Receptacles.
We, AERATORS LIMITED, of Broad Street Avenue, in the City of London, and
KENNETH SUTHERLAND MURRAY, of 17, Bedford Court Mansions, in the County
of London, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascer
tained in and by the following statement:-
This invention relates to the class of bottles, or receptacles, for aërated

page_text: liquids, commonly known as syphon bottles, or seltzogenes, from which the
aerated liquid is forced, in quantity as required, by the pressure of the gas in the
bottle, or receptacle; and the said invention has for its principal object to
provide improved means whereby the aëration of liquids in such bottles, or
receptacles, can be effected by liberating gas from a capsule, or container, in
which it is confined under pressure; the said capsule, or container, being, with
great facility, placed in, and removed from, a holder carried by the syphon-
Lead.
The draw-off valve, and the holder for the capsule, or container, of compressed
gas, (including in that term liquified gas) and also the means by which it is
pierced, or opened, are carried by a part capable of sliding vertically in the
syphon-head, and pressed downwards by a spring, so that the draw-off valve is
normally pressed to its seat but acts as a safety-valve to relieve excessive pressure
in the bottle, or receptacle.
The liquid is aërated by piercing, or opening, the capsule, or container, of
compressed gas, placed in the holder carried by the said sliding part; the gas
passing through passages (and also through a non-return valve if desired), in
the said sliding part, and down a tube, carried by the syphon-head and descend-
ing as usual to near the bottom of the bottle, or receptacle, but preferably having
the opening at its lower end provided with a ball, or other valve which closes
the said opening when the gas passes from the capsule, or container, and down
the said tube, so that the said gas is caused to issue through a small opening or
openings in the said tube, above the valve, in such direction as to facilitate its
absorption by the liquid in the bottle, or receptacle; whilst, when
the liquid is withdrawn, it lifts the valve and passes freely up the tube and through
the draw-off valve and out at the nozzle.
After the liquid has been aërated, a handle or device, can be operated to move the
said sliding part upwards in the syphon-head and open the draw off valve so
that aërated liquid is discharged at the nozzle.
In the accompanying drawings are illustrated arrangements according to this
invention.
Figure 1 is a vertical section, and Figure 2 is a side elevation, of an arrange-
ment according to this invention, wherein the capsule, or container, of com-
pressed, gas can be placed in position, and removed, without removing any part
of the apparatus for the purpose. Figure 3 is a vertical section of a modification
of the arrangement; and Figure 4 shews an arrangement in which the capsule,
or container, of compressed gas is introduced into a chamber above the draw-off
handle. Figures 5 and 6 shew an arrangement wherein the capsule holder and
perforator can be removed after aëration and Figure 5 shews also a filling
arrangement, and Figure 7 shews a similar filling arrangement applied to the
device represented in Figs. 1 and 2. In Figures 1, 2, 4, 5 and 6, the capsule,
or container, is presumed to require to be perforated to liberate the gas, and in
Figure 3 the capsule, or container, is presumed to be provided with a valve
requiring to be pushed inwards to liberate the gas. The syphon-head can be
secured to the top of the bottle, or receptacle, in the ordinary, or any suitable,
way which will form a good joint. Referring first to Figures 1 and 2; a web a,
is formed across the lower part of the interior of the syphon-head, and in this
web is a hole a², around the upper edge of which a valve seating is formed.
Above this web is a cylindrical chamber a, from the lower part of which is
carried the spout at, through which the aërated liquid is discharged. Above
the chamber ³, a continuation a³, is formed, closed at the top by the cover a,
and with a gap at one side, or opposite sides, sufficient to allow of the passage of
the capsule, or container, B, of compressed gas. C is a sliding part the lower
portion of which comprises a piston c, fitting into the cylindrical chamber a³,
and with its lower end reduced, and having, secured to it, the draw-off valve D,
containing elastic material d, to press against the valve-seat around the open-
ing a². Inside the piston c, is a web ², with an opening c³, through it, and

page_text: into the space above this is inserted a small block e, carrying the steel pin E,
by means of which the capsule, or container, B, is pierced. The block e, is
pierced vertically by holes e, which communicate with a horizontal passage e³,
which communicates with the hole, so that the gas discharged from the capsule,
or container, B. passes therethrough, and through the space below the web ²,
and through the opening 2, in the valve D, into the tube A, and thence into
the liquid in the bottle. G is a flexible seating into which the neck end of
the capsule, or container, B, fits to prevent the upward escape of gas when the
said capsule, or container, is pierced. A check valve F, (pressed upwards by a
spring ) can be placed within the space below the web, to prevent the gas, or
aerated liquid, from passing upwards through the hole c, if the capsule, or
container, be removed after aëration, or if it does not make a tight joint. The
upper portion of the part C, slides in the part a, of the syphon-head, the said
parte, having an opening at one side, or at opposite sides, to allow of the cap-
sule, or container, B, being placed in position, and removed, sideways. The
part C, can be moved up and down in the syphon head but is prevented from
turning therein which can be effected by making the parts a and c of square,
or equivalent form. A joint may be formed between the lower part of the
unreduced part of the piston and the upper part of the valve D, by inserting an
elastic ring in the space between them as shewn at h.
A spring presses upon the top of the sliding part C, to keep the draw-off
valve D normally to its seat, but yet to allow the said draw-off valve to act as
a safety-valve, by rising from its seat to allow of escape of gas by the spout a',
on any undue rise of pressure in the bottle, or receptacle. Through a plain
opening in the cover a, a spindle I is passed the bottom portion of which is
screwed through an internal screw in the head of the part ct. The upper end
of the spindle I, has a lever-handle i, centered to it by a pin .
At the bottom end of the tube A, is secured a small valve-chamber J, with an
opening, at bottom, over which a ball, or other retention, valve, ², seats
itself; are small holes directed upwards. The valve closes the opening j,
when the pressure is downwards and causes the gas to pass upwards through the
small holes, so that the gas is ejected very efficiently into the liquid. The
valve, rises to allow the liquid being withdrawn to pass freely into the tube A.
The action of the apparatus is as follows:-
Liquid having been introduced into the bottle, or receptacle, to the requisite
level and the syphon-head secured firmly in place, a capsule, or container, B, of
compressed carbonic acid, or other gas, is inserted sideways into place above
the piercing pin E, as shewn in Figure 1; the valve D, being held down upon
its seating by the pressure of the spring C. The spindle I is then rotated and
thus screwed down in the head of the part et so as to press the capsule, or con-
tainer, B, onto the pin E, which pierces the said capsule, or container, and, on
turning the spindle I slightly back, the gas is discharged therefrom and passes
through the passages e², e³, 3, and a into the tube A, and thence by the holes
into the liquid in the bottle, or receptacle. The downward movement of the
spindle I, brings the lever-handle against the bead a, on the cover a, and,
when it is desired to withdraw aërated liquid from the bottle, or receptacle, the
outer end of the said lever-handle is pressed down (the bead a acting as a
fulcrum therefor) and the sliding part C is thus raised, and the valve D lifted
from its seat, and aërated liquid is forced up the tube A and escapes past the
valve D, and through the spout, being prevented by the retention valve F
from escaping through the passage c³, if the capsule, or container, B, has been
removed after aëration or if it does not make a tight joint.
Figure 3 represents a modification wherein a cylindrical capsule, or con-
tainer, B, is used which is provided with a valve to be opened by pressure
instead of by piercing, and the pin E is therefore without a pointed end. The
parts which correspond with those shewn in Figures 1 and 2 are marked with
the same letters of reference and the foregoing description applies to them

page_text: also, except that the spindle I, instead of passing through a cover a, is screwed
directly into the top of the part and is removed for the insertion of the cap-
sule B, and the spring acts between a flange plate secured between the
portions of the part, and a flange. The upper portion of the parts and a
are made of hexagonal or other non-circular shape to prevent the sliding part C
turning in the syphon-head.
In Figure 4 is shewn a modification in which also the parts which correspond
with those shewn in the preceding figures are marked with the same letters of
reference the foregoing description of Figures 1 and 2 applying to them also.
In this arrangement however the sliding part C is continued up through the
cover, and the receptacle for the capsule, or container, of compressed gas is
at top and a cap K is screwed down onto the top of the said part C to effect
the piercing, the pin E being in the upper portion of the sliding part C and the
opening being continued through the prolongation of the said sliding part C
between the said pin and the retention valve F. The draw-off lever handle is forked
so that the prongs of the fork (one of which is shewn at ) lie on each side of the
sliding part C, and, when the outer end of the said lever is depressed, lift it by
bearing on the flanged part above them, the rounded projections engaging in
recesses in the cover a acting as fulcra. The clastic joint G has a metal thimble,
in it containing elastic material to make a tight joint when pressed up by the gas.
Figure shews the invention as applied to a syphon-head in which provision
is made for introducing the liquid without removing any part of the said head
except a cap covering the inlet for liquid. The parts which correspond with
those shewn in the preceding figures are marked with the same letters of reference.
The valve F is shewn in a chamber above the lever handle instead of in a
lower chamber, and instead of the part carrying the spout at being secured
directly to the bottle, or receptacle, it is secured to a shell or casing M which
is. secured to the bottle or receptacle, there being sufficient space between the
part carrying the spout at and the shell or casing M to allow of liquid intro-
duced by the inlet opening m passing into the bottle or receptacle. The open-
ing at m is covered by a screw-cap m² with a leather or other joint to give a
tight closure. In full lines the inlet m is shewn directed upwards for filling
whilst the bottle or receptacle is standing on its base but in order to insure
that the bottle or receptacle shall only be filled to the requisite level the said
inlet m may be directed out horizontally, as indicated by dotted lines, so that
the bottle, or receptacle, is placed on its side to be filled and the liquid will
overflow at the inlet when the requisite quantity has been introduced. The said
arrangement for filling can be applied to either of the arrangements shewn in
the other figures, for instance in Figure 7 it is shewn applied to the construction
of syphon-head represented in Figures 1 and 2, m indicating the inlet and m
a screw plug or stopper which, in this example, is used in the place of the
cap m² shewn in Figure 5. Figure 5 also shews an arrangement wherein the
part (Figure 6) which carries the capsule or container B and the perforating
device E is made separable so that on being removed it can be used for charging
any number of bottles or receptacles. The part for carrying the capsule or
container B and the perforating device E (Figure 6), when the liquid in the
bottle or receptacle is to be charged with gas, is screwed on in place of the
dust cap n (Figure 5) which is removed for the purpose. When charging has
been effected the part shewn in Figure 6 is removed and the dust cap n is
screwed in place. In order to prevent the necessity for turning back the
handle or its equivalent to allow the gas to pass out of the capsule or container
the pin E may have a perforation through it.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
1. The combination with a syphon-head of a sliding part which comprises, or

page_text: carries, the draw-off valve; a holder for the capsule, or container, of compressed
gas; and a device for releasing the gas therefrom; and a passage for the escape
of the released gas into the liquid to be aërated; substantially as hereinbefore
described.
2. The combination with a syphon-head of a sliding part which comprises, or
carries, the draw-off valve; a holder for the capsule, or container, of com
pressed gas and a device for releasing the gas therefrom; and a passage for the
escape of the released gas into the liquid to be aërated; and a retention valve
to prevent return of gas, or liquid, by the said passage; substantially as herein.
before described.
3. The combination with a syphon-head of a sliding part which comprises, or
