Improvements in or Appertaining to Bottles, Syphons, Gazogenes,
and other Receptacles for Aerated and other Liquids and Gases,
and in the Means for Hermetically Closing the same and
Withdrawing their Contents.
I WILLIAM PURVIS WILSON of 6 Westminster Chambers, Victoria Street, in the
City of Westminster, Engineer do hereby declare the nature of this invention to
be as follows:
This invention has for its chief object a simple and effective arrangement for
hermetically closing the mouths or outlets of bottles, syphons, gazogenes and other
receptacles whilst permitting their contents to be either wholly withdrawn without
waste, or only partially withdrawn at intervals, and preserving the remaining contents
from deterioration.
I obtain this result by the employment of tubular or of solid adjustable plug
stoppers in combination with valves of spherical or other form either attached to
or separate from the stopper which serves to control the valve. The said valve and
stopper are by preference so disposed as to he always covered or sealed by the liquid
in the bottle or other receptacle so that by a slight movement of the stopper without
withdrawing it from the neck of the receptacle the contained liquid mixed with
the gas is at once discharged in lieu of a portion of the fixed air being allowed to
escape on opening the bottle before the liquid is poured out as is the case with
ordinary aërated water bottles.
By ensuring the discharge of the liquid in company with the gas without any
previous loss of I obtain improved hygienic results from the fact of the tempera-
ture of the liquid being lowered at the moment of its discharge by the expansion
of the gas with which it is saturated.
I employ a special form of neck for the reception of the aforesaid valve and
stopper which neck is formed with internal valve seats suited to the kind of valve
employed said valve being operated upon by a slight rotary movement of the
stopper inside the neck, the stopper being provided with screw threads or with snugs
working along inclined projections formed inside the neck the said snugs being

page_text: entered through slots in the said inclined projections so that the stopper will always
he retained in the neck. Or if desired the stopper may act upon the valve by direct
pressure provision being made for the entire removal of the valve and stopper
when necessary for cleaning or filling the bottles or receptacles.
In carrying out this part of my invention I construct a valve seat in the neck of the
bottle or vessel so arranged as either to permit of the valve being opened by being
moved inwards or outwards under the action of the stopper, the internal pressure
in the receptacle keeping the valve closed in most cases. The heads of the stoppers
may be enlarged and packed underneath with rubber packing, or rubber packing may
be placed inside the neck at the inner end of the stopper. In some cases the head of
the stopper may be in the form of a cap fitting the outside of the neck which may
be provided. with external screw threads or with inclined surfaces to enable the
stopper to be moved inwards or outwards either by turning the same or by direct
pressure as preferred.
The before mentioned arrangements for withdrawing the contents of receptacles
are specially applicable to syphons and gazogenes of various forms and enable me to
adopt certain novel constructions of such receptacles which are specially suitable
for the preservation of the liquid contained therein. For example according to
one arrangement I enclose the powder chamber within which the gas is generated,
inside the body of the main vessel itself which contains the liquid to be aërated
the said powder chamber being provided with a neck which is permanently united to
the neck of the main vessel and is formed with the requisite valve seat or seats
to accomodate the valve and if desired to receive the actuating stopper; the valve in
the neck of the internally disposed powder chamber is intended more particularly for
facilitating the charging of the vessel for which purpose the actuating stopper may be
dispensed with, but if desired the valve may be so arranged as to be utilised for
drawing off the contents from the top of the Gazogene but I prefer to apply
a separate arrangement of valve and stopper for the withdrawal of the contents of the
main vessel, fitted into a socket formed on the outer surface of the said vessel
in any convenient position. I thus avoid the use of costly and objectionable metal
mounts and syphon tubes in vessels of this description. In syphons and vessels that
are charged direct with liquids under pressure I apply my aforesaid valve and stopper
to a socket or neck of the required construction formed in any convenient part of the
outer surface of the vessel by preference at or near the bottom thereof-I also
propose to apply my aforesaid arrangement of valve and actuating stopper to
closed vessels for containing beer, wines or other liquids in which case I apply
the draw off arrangement to the base of the vessel. The liquid can be drawn off
centrally through the stopper itself when a tubular stopper is employed, or it may be
drawn off by a lateral discharge tube or nozzle connected with the valve chamber
when using a solid stopper.

I WILLIAM PURVIS WILSON of 6 Westminster Chambers, Victoria Street in the
City of Westminster Engineer do hereby declare the nature of the said invention
and in what, manner the same is to be performed to be particularly described and
ascertained in and by the following statement thereof :-
23
::
This Invention relates to a simple and economical combined closing and draw off
arrangement applicable to hottles and other receptacles whether for containing still
liquids or intended to be charged direct with liquids or gases under pressure (such for
example as are commonly known as "Syphons") also to receptacles generating their
Own gas such as "Gazogenes Seltzogenes and the like whereby the costly and
objectionable metal mounts and syphon discharge tubes hitherto required in
Gazogenes" and "Syphons can be superseded whilst facility is afforded for either
wholly withdrawing the contents of the bottle or other receptacle at once without
waste or for only partially withdrawing the same at intervals as required for con-
sumpton at the option of the user preserving in the latter case the remaining contents
from deterioration.
::
::
Also to certain further improvements partly applicable to Gazogenes fitted or not
with my combined closing and draw off arrangement and partly applicable to air
tight closed receptacles for liquids generally when fitted with my combined closing
and draw off arrangement whereby the construction of Gazogenes is further simplified
and a better preservation of the contents of the air tight closed receptacles is effected
by ensuring that the neck or discharge orifice shall always remain sealed by the
enclosed liquid when the contents are being wholly or partially drawn off or the
receptacle is in use.
My improved combined closing and draw off arrangement consists according to one
modification of a peculiar hollow or tubular valve-actuating discharge stopper or
mouthpiece screwed in or otherwise engaged with the neck of the receptacle and so
formed as to bear at its inner end upon the outer portion of an internal loose valve
for the special purpose of opening the same by forcing it from its seat which is
elastic or flexible and is independent of the hollow stopper it being fitted into an
annular groove in the neck of the receptacle by preference at a distance from the
inner end of the female screw therein. The loose valve is maintained closed against
its seat in the usual way by the internal pressure but is opened by screwing inwards
the said mouthpiece and immediately closes again when the mouthpiece is turned in
the reverse direction-According to another modification the valve is attached to or
formed on the inner end of the tubular stopper itself, in this modification the seat may
be elastic or flexible and fitted as previously described into an annular groove in the

page_text: neck of the receptacle or it may be rigid and moulded or formed in one with the
interior of the neck in which latter case I prefer that the valve be wholly or partially
covered with flexible or clastic material. The valve is closed by screwing inwards
the tubular discharge stopper or mouthpiece and opened by turning the said stopper
in the reverse direction, or the valvular orifice may be closed by the internal pressure
forcing the flexible valve scat outwards against the valve.
When a loose valve is employed it may be prevented from falling into the body of
the receptacle hy a removeable cage of wire metal strips or other suitable material
fitted into the neck of the receptacle, this cage is obviously applicable to most.
internally stoppered bottles and obviates the necessity for contracting the lower part
of the neck. The discharge orifice with its valve and tubular discharge stopper or
mouthpiece should be so situate on the receptacle as that the valve shall always be
covered or sealed by the contained liquid when the contents are being drawn off or the
vessel is in use. In this condition a slight inward or outward movement as the case
may be of the tubular stopper produced by turning it more or less in the neck of
the receptacle will effect the opening of the valve and the whole or any portion of the
contained liquid will be discharged through the tubular stopper simultaneously with
the gas or fixed air in lieu of a portion of the fixed air under pressure being allowed
to escape before the liquid is poured out as is the case with the modes heretofore
proposed of opening bottles containing liquids under pressure. By thus ensuring the
simultaneous discharge of the liquid and gas I obtain improved hygienic results by the
lowering of the temperature of the liquid jet at the moment of the discharge produced
by the expansion therein of the gas or fixed air with which it is impregnated. The
hereinbefore described valve-actuating hollow mouthpiece or stopper is free to be
turned by hand more or less in either direction in the neck of the receptacle without
being withdrawn therefrom except for cleaning or filling.
Fig. 1 is an elevation of a well known make of aërated water bottle with the upper
part of the neck in section shewing the application thereto of our form of combined
closing and draw off arrangement.
a is the neck of the bottle or receptacle formed with internal screw threads and an
annular groove at a short distance beyond the female screw to receive an elastic or
flexible annular valve seat c against the underside of which the loose or spherical
valve d is maintained closed by the internal pressure in the bottle as is well under-
stoode is my peculiar hollow or tubular valve-actuating screwed stopper or mouth-
piece hereinafter called the " stopper" which engages with screw threads formed
inside the neck of the bottle and being tubular affords a passage for the discharge of
the contents when the valve is opened by being forced from its seat by the inward
screwing of the said stopper. The lower end of this. stopper is by preference of
smaller diameter than the opening in the valve seat and is of a somewhat conical
form and projects sufficiently beyond the screwed part-to bear upon the upper or outer
surface of the valve d when the latter is in its closed position as shewn in the drawing.
is a central discharge passage or thoroughfare passing through the stopper and
opening through the sides of the inner conical end thereof by lateral orifices above
the valve seat so that when the bottle is held in an inverted position and the valve dis
opened which is effected by screwing the stopper e inwards more or less the liquids
and gas will escape together through the central passage as indicated by the arrows
the flow being regulated or shut off entirely by a slight turn of the stopper in the
proper direction inside the neck of the bottle but without removing it therefrom.
g is an enlarged head formed upon the said stopper to facilitate the turning of the
same. is a rubber or other suitable packing ring underneath the head used in
conjunction or not with a second packing ring round the inner end of the screwed
part of the stopper as a preventive of leakage between the stopper and the neck of
the bottle The packing ring should be sufficiently compressible to allow the stopper
to be screwed in far enough to open the valve d. k is a projecting discharge lip
formed on the head of the stopper to improve the jet and prevent drip.
Fig. 2 is a vertical section of a slightly modified arrangement wherein the lower
end of the stopper is so formed as to completely fill or close the opening in the

page_text: annular valve scat e by the time the stopper has been screwed inwards sumciently to
open the loose valve d thereby preventing all access of the liquid between the stopper
and the neck of the bottle and obviating the necessity for the packing rings h and i
shewn in fig. 1. The central discharge thoroughfare in this stopper is continued by
one or more apertures direct through to the inner end of the stopper in lieu of
branching out by lateral passages above the valve seat as in Fig. 1.
of
Fig. 3 is a vertical section of a similar arrangement to fig. 1 with this exception
that the stopper e is formed with a cap el having internal screw threads made therein
engaging with corresponding screw threads formed on the exterior of the neck
the bottle in lieu of in the interior thereof. The lower end of this stopper may also
be made similar to that in Fig. 2.
Fig. 1 is a vertical section of another modification and Fig. 5 is a separate detail in
vertical section of the neck of the bottle shewn in Fig. 4 with the stopper removed.
In these figures the screw threads on the stopper and inside the necks respectively
are replaced by projecting snugs (Fig. 4) on the stopper and two or more internal
projecting ledges m (fig. 5) inside the neck of the bottle these ledges being each
inclined on the underside and made to extend say about half way round the neck.
Or this arrangement may be reversed by forming the snugs in the interior of the neck
and the inclined ledges on the stopper.
In the modification shewn in elevation and partial section at fig. 6 the snugs are
formed inside a cap el made in one with the stopper and engaging with corresponding
inclined ledges m formed round the outside of the neck. This arrangement may also
be reversed by forming the snugs on the outside of the bottle and the inclines in the
interior of the cap e¹. In some cases I make the inclined ledges m each with its
shallowest part at its two extremities and its deepest part in the middle as shewn in
fig. 5. so that the stopper after it has been inserted can be turned in either direction
about a quarter of a revolution in order to effect the opening of the valve by pressing
it from its seat. Or if preferred the underside of each of the said ledges towards its
shallowest end may be in a plane perpendicular to the axis of the neck for a short
distance or say one quarter of the circle from which point they gradually incline
inwards or downwards till they reach their greatest depth at the opposite extremity of
the ledge as shewn in Fig. 6. In all cases a free space must be left between the
contiguous ends of the inclined ledges m for the entrance of the snugs thus when
the stopper is first pushed into the bottle the snugs pass just below the shallow ends of
their respective ledges and by turning the stopper slightly it will be locked inside the
neck but by continuing the rotation of the stopper till the snugs enter upon the
inclined portion of the ledge shewn in fig. 6 the stopper will be moved inwards more
or less and will eventually open the valve d by pushing it away from its seat as
already described.
When a loose internal or ball valve is to be used in connection with the neck of a
bottle not made with the well known contraction shewn at n in fig. 1 a removeable
cage o may be provided as shewn applied to a bottle neck in fig. 7 to catch the said
valve when it is forced from its seat. This cage may consist of two wires crossing
each other and soldered together in the middle or of a thin sheet of metal stamped out
in the form of a cross the wires or the metal strips as the case may be being curved
upwards and bent outwards at their extremities so as to form catches which spring
into the annular groove or recess containing the valve seat c said groove thus
holding the cage o as well as the valve seat in position. This cage is equally
applicable to the discharge nozzles of gazogenes and of other closed receptacles fitted
with my combined closing and draw off arrangement as shewn in figs. 9, 10, 11
and 12 hereinafter more fully referred to and can be readily removed along with the
valve seat to facilitate the cleaning of the vessel and replaced again.
Fig. 8 is a vertical section of a further modification of my combined closing and
draw off arrangement. The valve d is formed in one with or is attached to the inner
end of the stopper e in lieu of being loose or detached therefrom as in all the arrange-
ments hereinbefore described. In this modification when used with liquids or gases
under pressure the annular valve seat e should be flexible and project far enough

page_text: inside the neck to present a sufficient area for the internal pressure to act upon to
enable it to be deflected outwards and maintained closed against the valve d. The
stopper may be connected to the neck of the receptacle by any of the methods
herein before described-When applied to receptacles for containing what are commonly
known as "still liquids a rigid valve seat may be employed and the closure would
then be effected by screwing home against. its seat the valve portion d which in
that case should be composed of or wholly or partially covered with rubber or other
yielding material.
My further improvements in Gazogenes and other air tight closed vessels consist as
regards Gazogenes in enclosing the chamber for containing the gas generating
powders inside the main receptacle which contains the liquid to be aërated also in
providing bottles, gazogenes and closed receptacles for liquids generally when fitted
with my combined closing and draw off arrangement with trunnions so placed that
when suspended between suitable standards or supports the bottle gazogene or other
receptacle shall hang in an inverted position or with its discharge nozzle downwards
thus effecting the better preservation of the contained liquid by ensuring the seating
or covering of the discharge valve whilst enabling the receptacle to be swung to any
suitable angle for bringing the nozzle conveniently over the edge of the glass into
which the contents are to be drawn off.
Fig. 9 is a vertical section of a gazogene fitted with one of my combined closing
and draw off arrangements and further constructed in accordance with my invention."
con-
is the receptacle of spherical cylindrical or other form for containing the liquid to
be aërated. is the chamber for the reception of the gas generating powders which
chamber is enclosed inside the receptacle p, it is formed with a nozzle projecting
through the side of pand is fitted with a suitable valve and seat through which the
gas generating powders are introduced. s is a separate nozzle formed on the
receptacle p through which the liquid to be aërated is introduced into and the aerated
liquid is drawn off from the said receptacle said nozzle being provided with any of
the improved combined closing and draw off arrangements hereinbefore described. In
constructing this Gazogene the powder chamber with its nozzler may be made in
one piece of glass separate from the body of the receptacle and fused worked or
welded inside the receptacle p whilst both the parts are in a sufficiently heated
condition to become effectually and permanently united together as will be readily
understood by a glass worker. t is a tubular continuation of the chamber
stituting a deep pocket closed at its lower end and extending nearly to the bottom of
the receptacle p but opening at its upper end into the chamber 7. is a tube also
opening at its upper end into the chamber whilst its lower end opens direct into the
lower part of the receptacle the said parts & and t¹ being by preference made in one
with the powder chamber and nozzler. In an annular groove or recess formed
inside the nozzle there is fitted a rubber or other elastic or flexible valve seat
against the underside of which a conical or other valve u is maintained by the internal
pressure so soon as sufficient gas has been generated as hereinafter described. A
wire or other handle attached to the valve u facilitates the opening of the same
when introducing the gas generating powders. To facilitate the reversing of the
position of the receptacle p for the purpose of charging it and in order to support it
when ready for use with its discharging nozzle downwards to ensure the sealing of
the discharge valve and tubular stopper and thereby effect the better preservation of
the liquid provide such receptacle with trunnions as shewn dotted at w thereby
enabling the receptacle to be suspended between convenient standards not shewn in
fig. 9 but shewn dotted in fig. 10. It may also be provided with the usual supporting
feet or stands on opposite sides of the vessel at any convenient angle upon one
or other of which feet the gazogene may be stood as required when lifted out of its
supporting standards. When the receptacle is to be charged with the liquid to be
aerated it is to be reversed for the time being so as to bring the nozzle s to the top,
the loose valve d then falls into the cage o the stopper e is removed and a suitable 5
filler is introduced through the nozzle s so as to direct the liquid into the body of the
receptacle p which is to be nearly filled leaving the usual gas space above it whilst

page_text: the confined air escapes through the same nozzle. The stopper e is then replaced and
the receptacle is reversed to the position shewn in fig. 9 the orifice in the stopper
being kept closed by the finger during the reversing of the receptacle or until the
valved has closed against its seat again. The valve in the nozzle which is thus
brought upwards is now pushed inwards and sideways so as to close the mouth of the
tube whilst leaving the mouth of the pocket t open for the reception of the gas
generating powders which are also introduced into the chamber through a filler and
descend into the pocket a little water being then added in order to start the
generation of the gas. The operator now brings the valve u against its seat as shewn
in fig. 9 where it is held closed by the pressure of the gas in the chamber The
gas as it is generated passes as shewn by the small arrows down the tube t to the
bottom of the receptacle and rises through the liquid thereby impregnating the same.
The liquid when thoroughly impregnated can be drawn off at will in any desired
quantities by turning more or less the tubular stopper in the nozzles as already
explained. In order to admit of a glass being conveniently placed under the mouth
of the discharge nozzle the receptacle p may be stood with its foot upon a separate
pedestal or support of convenient height but when supported by the trunnions won
standards facility is afforded for swinging or turning the receptacle to any desired
angle so as to bring the nozzle s well over the glass or receiving vessel.
Fig. 10 is a vertical section of a modified form of my improved Gazogene wherein
the nozzle is dispensed with and one and the same valvular nozzles serves for the
charging of the powder chamber the filling of the receptacle p with liquid and the
withdrawal of its contents the apparatus being shewn in the position for being
charged.
7
In this arrangement I have also shewn the receptacle pas suspended by trunnions w
in standards or supports y indicated in dotted lines but broken away at the bottom-
The powder chamber is formed in one with the deep pocket and tube t' as in
fig. 9 and
similarly contained inside the main receptacle p but is here represented
as worked or welded into the base or foot -The receptacle p is charged with the.
liquid to be aërated by a filler inserted through the nozzles and passed outside the
tube the loose valve d being dropped to one side in the removeable cage o as shewn
in dotted lines to allow of the passage of the filler. The powders are introduced
through a filler inserted into the open mouth of the tube t¹ and fall into the chamber
at the bottom. The vessel is then turned over in the direction of the arrow upon the
trunnions the height of the standards or supports y being by preference such as to
admit of the placing of a glass or receiving vessel beneath the draw off nozzle s when
in its reversed position for discharging the contents. The reversing of the receptacle p
causes a portion of the contained liquid to flow along the tube and to mix with the
gas generating powder which in the act of turning falls into the pocket t. The gas
thus generated escapes down the now inverted tube to the lower part of the receptacle
and rises up through and impregnates the liquid. If desired a separate discharge tube
bent to any convenient form may be combined with and fitted fluid tight into the
tubular stopper but in such a manner as to allow of the free turning of the stopper
inside the neck or nozzle of the receptacle round the said discharge tube whereby
facility is afforded for placing the discharge nozzle with its valve and tubular stopper
in any position on the receptacle p that will ensure the sealing of the nozzle during
the withdrawal of the contents whilst at the same time affording space for the con-
venient placing of a glass or other receiver beneath the outlet of the said discharge tube.
Fig. 11 is an elevation and partial vertical section of an air tight closed receptacle
of cheap and simple construction fulfilling all the requirements of the more costly
and complicated "Syphon vessels" hitherto employed but without the objectionable
metal mounts and internal syphon or draw off tubes usually required in vessels of that
class.
Fig. 12 is a similar view of a like receptacle of slightly modified form.
p is a closed receptacle of glass porcelain or other suitable material having
supporting feet or stands and formed at the bottom and top thereof respectively
which serve also in some cases as handles-The said receptacle is further provided

page_text: with trunnions w formed either on the opposite sides of the top foot or stand ¹(see
Fig. 11) or on the sides of the receptacle itself (see Fig. 12). At or near the bottom
of the receptacle there is also formed in one therewith a draw off and charging neck
or nozzle s fitted with any one or other of my herein before described combined closing
and draw off arrangements, that shewn in Figs. 11 and 12 being the same arrange-
ment as Fig. 1-The said neck or nozzle s may either be formed on one side of the
receptacle at any convenient angle (see Fig. 11) or it may be formed so as to
project perpendicularly from the bottom of the receptacle (see Fig. 12) is the
removeable cage (hereinbefore described with reference to Fig. 7) for preventing the
loose valved from entering the body of the receptacle when reversed for being filled ;
although I prefer to use the cage o the mouth of the neck or nozzle may be contracted
at its inner end for the same purpose as is well understood. When being charged
with liquid the receptacle p is stood upon the foot a¹ so as to present the nozzles
upwards but when charged and in use it is stood upon the foot or feet or which I
prefer is suspended by the trunnions in standards or supports with its nozzle down-
wards as described in reference to my improved Gazogenes the receptacle being thus
free to be tilted to any convenient angle on its trunnions when in use for the accomo-
dation of a glass under the mouth of the stopper. If preferred the receptacle p
may he stood upon a separate raised support or stand when in use for the more
convenient accomodation of a glass under the discharge orifice. These receptacles
may be used for either aerated or still liquids but in the latter case they should be
fitted with the draw off arrangement shewn at fig. 8. I may also provide ordinary or
other bottles when fitted with my combined closing and draw off arrangement with
trunnions was shewn dotted in fig. 1 for the purpose already described. My improved
Gazogenes and other receptacles for liquids under pressure will be provided with the
usual protecting guards or cages of cane or wire work if found requisite as is well
understood.
In order that my improved combined closing and draw off arrangement may be
readily applied to the plain necks of ordinary bottles Syphon-vessels and the like I
combine the same with metal mounts adapted to be cemented or otherwise fixed to the
neck of the receptacle as shewn in figs. 13 and 14 where A is the metal mount formed
with a socket B fitting onto the plain neck C. In fig. 13 the female screwed part of
the metal mount which receives the valve-actuating hollow stopper or mouthpiece e is
above the neck and in fig. 14 it is enclosed inside the same.
I am aware that prior to my invention it has been proposed to employ in combi-
nation with the neck of a bottle a screwed hollow mouthpiece or stopper with or
without an enlarged head, an elastic valve seat, pressed against a ledge or shoulder in
the neck by the inner end of the said mouthpiece and a loose spherical valve main-
tained close by the internal pressure but the said mouthpiece was not adapted for
acting directly upon and opening the valve by forcing it from its seat. The said
arrangement differs materially from mine both in the construction and arrangement of
its parts and in its mode of action. To open the bottle it was necessary first to get
rid of the internal pressure on the loose valve by allowing the gas to escape before
any liquid could be poured out and hence it was not adapted for permitting of the
simultaneous discharge of the gas and liquid nor for the withdrawal of portions of
the contents at intervals whilst preserving the remainder and therefore I lay no claim
to such an arrangement neither do I claim as forming part of my invention a screwed
hollow or tubular discharge stopper or mouthpiece formed with an enlarged head
when not so made as to operate directly upon the internal valve.
To enable a bottle maker to produce the form of neck required for my aforesaid
combined closing and draw off arrangement I will here describe a special tool suitable
for that purpose which I have claimed in the Complete Specification accompanying my
application for Letters Patent lodged on the same date as that of the filing of this
Specification. This tool is so arranged as to form the annular groove for the valve
seat and the female screw inside the neck at one and the same operation leaving a
plain space between the inner end of the female screw and the outer side of the groove
by preference of the same diameter of bore as the part below the groove as shewn.

elevation and partial section of the tongs employed. Figure 16 is a longitudinal
section of the operating end of the tool looking at right angles to Figure 15 and
Figure 17 is a transverse section taken along the line 1-2 in figure 16 looking
towards the end of the bottle neck. 1 is a hollow plug or mandrel fixed to the plate
and carrying an additional separate loose collar 3 having a male screw thread
corresponding to the female screw to be produced inside the neck. This collar turns
freely round the plug 1 and has a flange which connects it to the plate 2 in which it
also turns when not locked or fixed by the action of the tongs as hereinafter explained-
44 are two arms carrying dogs 55 and hinged at 6 6 to the ends of the hollow plug.
These dogs play in and out through openings in the sides of the plug near its inner
end. Along one side of the plug works a slide 7 provided with a feather 8 which
locks the collar 3 to the plug by entering between pins or stops in a circular recess 9
in the end of the collar. Wedge pieces 11 and 12 are formed on the two ends
respectively of the slide 7-13 are the dies for shaping the outside of the neck
carried as usual on the free ends of the legs 14-15 is the central rod U shaped at
the end and fixed to the plate 2. 16 is a slotted bent lever connecting the slide 7 with
the legs in such manner that when the dies 13 are opened the slide 7 will be forced
inwards thereby locking the screwed collar on the plug by the entrance of the
feather 8 between any two of the pins or stops in the circular recess in the collar.
The same movement causes the dogs 5 to withdraw inside the plug by the entrance of
the wedge piece 11 between the tail ends of the arms 4-In this condition the tool is
ready for application. A ring of molten glass is placed round the neck of the bottle
and the plug and screwed collar introduced therein-The dies 13 are then closed upon
the molten glass which movement causes the dogs 5 to be forced outwards as shewn
in the drawing by the action of the wedge piece 12 the same movement releasing the
collar 3 and allowing it to revolve freely round the plug along with the bottle the
protruding dogs 5 remaining stationary during the revolution of the bottle and conse-
quently producing an annular groove inside the neck. When the dies 13 are opened
preparatory to releasing the bottle the tool resumes its original condition that is to say
the screwed collar is locked and the dogs withdrawn inwards to allow the bottle neck
to be unscrewed by its rotary motion.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. A combined closing and draw off arrangement for bottles gazogenes and other
closed receptacles wherein a rotary tubular discharge stopper or mouthpiece connected
by screw threads or their equivalent with the neck or nozzle of the receptacle is
caused to bear directly against the outer surface of an internal loose valve which is
opened or forced inwards from its seat by turning the said stopper or mouthpiece in
one direction and closed by the internal pressure in the receptacle when the mouth-
piece is turned in the reverse direction as hereinbefore described and illustrated by
figs. 1 to 6 of the drawings annexed.
2. The combination with the neck or nozzle of a bottle or other closed receptacle
provided with an internal loose valve of an inner removeable cage for preventing the
entrance of the loose valve into the body of the receptacle as herein before described
and illustrated by Fig. 7 of the drawings annexed.
3. In a combined closing and draw off arrangement for bottles gazogenes and other
closed receptacles a rotary screwed stopper or mouthpiece acting at its inner end as a
valve against a valve seat inside the neck and formed with a discharge outlet commu-
nicating by lateral orifices with the outerside of the said valve seat as hereinbefore
described and illustrated by fig. 8 of the drawings annexed.
4. Forming the necks or nozzles of bottles and other receptacles to which the
aforesaid closing and draw off arrangements are to be applied with an intermediate
plain portion between the inner end of the female screw which receives the tubular
stopper or mouthpiece and the outerside of the annular groove which receives the
internal valve seat as specified.
