PROVISIONAL SPECIFICATION.
Improvements in or connected with the Manufacture of Syphons
and Seltzogenes, or parts thereof, for Aërated Waters."
I, HENRY LOUIS PHILLIPS of No. 57 Moorgate Street, in the City of London,
Gentleman do, hereby declare the nature of this invention to be as follows:-
:-
My present invention relates to improvements in or connected with the manu-
facture of syphons seltzogenes and the like, or parts thereof, for aerated waters.
As is well known, syphons of the kind above referred to, consist of two separate
principal portions, cit., the vase or body made of thick glass for containing the
carbonated liquid, and the head-portion made from metal, and attached to the neck
of the vase, such head-portion having a nozzle or opening through which the
syphon is filled and emptied under pressure; a lever which operates an internal
valve to open, and close the nozzle or opening; and such head-portion also
containing the springs valves, washers, and other necessary parts.
Hitherto, the heads of all such syphons have been made, or cast from metal
(generally lead or an alloy thereof) but the chemical reaction of mineralised or
acidulated waters upon such metal, has been long recognized by medical inen as
injurious to health. I am aware that efforts have been made to overcome that
objection by lining the metal syphon-head, or those parts thereof which necessarily
come in contact with the carbonated liquid, with pieces of comparatively thin glass
tubing; but such separate pieces have either .to be first carefully put together or
have to be joined or blown together by means of fire, and then the metal alloy
which forms the syphon-head is melted and cast over the thin glass tubing. This
process is found to be slow, troublesome, and expensive, owing to the care required
in putting the various parts together in the first instance, and to the considerable
amount of glass tubing which is destroyed during the risky operation of covering
it with the hot metal.
My novel invention has for its object the forming the solid head of the syphon
for the purposes set forth, entirely from glass, so that the carbonated liquid in its
passage into and out of the syphon cannot be poisoned or contaminated by contact
with any metal whatsoever. By my novel device I not only dispense with the use
of metal in the construction of the syphon head; but by the means hereinafter set
forth I materially lessen the cost of its manufacture, and at the same time produce
a perfectly unobjectionable article.
In its external form, my improved syphon is similar to those in general use; but
I preferably make the separate head portion thereof entirely from plastic glass by
pressure as hereinafter appears. It is provided with a suitable nozzle for filling
and discharging the syphon, and in the interior of the head I place controlling
valves and other parts which I sometimes prefer to make of glass, and such valves
are operated by means of a lever made of any suitable substance.
I construct my improved glass syphon-head with two central internal vertical
chambers communicating with each other, the upper one being the smaller, and the
lower one devised to communicate with the nozzle opening aforesaid, and also with
the interior of the vase or body portion which holds the carbonated liquid. A
glass pipe or syphon tube of the size required passes from the interior of the
syphon-head to nearly the bottom of the vase, and in such tube is placed a glass
rod extending to its lower end. Such rod will be formed with an enlarged end
portion upon which will be fitted an india rubber ring. The lower end of the tube
will have a bell mouth, against the inside part of which the rubber ring will press,
and thus make a joint to prevent the liquid rising in the syphon tube, except when
such rod (and the valve attached) is depressed by the lever aforesaid. The upper
end of the syphon-tube is formed with a bell mouth or an outwardly turned flange,

page_text: and by means of suitable washers, an air tight joint is made between such tube, the
mouth of the vase, and the interior of the syphon-head.
The upper end of the glass valve rod is carried into the smaller or upper chamber,
and is provided' with a head round the underside of which is fitted a rubber or
other washer. Such washer is about the same diameter as the upper part of the
larger chamber against which it is devised to fit, and thereby serves (in addition to
acting as a spring; as is hereafter described) to prevent the aerated liquid from
penetrating into the upper chamber, and escaping past the inner end of the lever
when the syphon is being filled or emptied.
To prevent the washer described from falling from its proper position, I place in
the lower chamber a short cylinder (such as a short piece of suitable glass tube)
which has its upper end flanged or enlarged to the size of the diameter of the
chamber. Its lower end is also similarly enlarged but is also made with wave-
shaped or other shaped openings in its edge for the purpose below described. The
edge rests on the inside of the bell mouth at the upper end of the syphon tube and
the cylinder is of such length, that when in position, its upper end will press against
the washer and hold it up in place.
When the glass valve-rod is depressed by means of the lever, the centre of the
washer (which in such case acts as a spring) will also be depressed, the valve at the
bottom will be opened, and thus the liquid will be discharged. When the pressure
upon the lever is removed, the spring washer will rise, and so lift the glass rod and
thus close the valve.
The short cylinder, or piece of glass tube, will be of such external diameter as to
allow of an annular space between it and the wall of the chamber. The nozzle
opening will communicate with such space. The wave-shaped edge of the short
cylinder will allow of the free passage of the liquid into the annular space.
The upper chamber through a lateral opening or slot made in it, will receive the
end of the lever which end will be placed in a recess formed therein. The lever, on
its underside, will have a curved portion devised to rest upon a short distance piece,
of glass or other suitable substance. The lever may if desired be made of celluloid,
horn, bone, or other unobjectionable substance, less liable to fracture than glass.
In some cases the loose distance piece may be dispensed with; and the curved part
of the lever then brought directly upon the end of the glass rod. Sometimes in the
upper chamber I use a metal spring in place of rubber.
Sometimes also, instead of a long rod, I prefer to use a short glass rod and then
to place the valve in the syphon head instead of at the bottom of the syphon tube.
The syphon tube in such case, will be adapted accordingly, and if necessary, F
employ extra washers to carry out such arrangement.
I sometimes make the short cylindrical piece above described, without a wave-
shaped edge portion, and to permit of the free passage of the liquid I prefer to
make one or more holes through its side. It may be made also of other form.
I sometimes use other springs and valves than those herein described. Sometimes
also, I employ split washers for the purposes set forth, and sometimes I make them
of glass or other suitable substance.
I can attach my novel glass head portion to the vase in the manner generally
adopted; but I sometimes prefer to form a screwthread in the lower part of my
glass syphon-head devised to operate upon a corresponding screwthread formed
upon the neck of the vase or upon a screwthreaded separate collar made from
celluloid, horn bone or other substance, such collar. being devised to come under au
annular projection on the neck of the vase, and being in-halves, is kept together
and in place, by the head being screwed upon it.
ว
The glass nozzle may be sometimes protected by an external metal collar or band
of any size. This may be fitted into a depression formed on the nozzle. The
nozzle may also be formed separately and fixed to the head by screwing it thereto.
Sometimes I protect the glass nozzles with sleeves, or covers of cheap material such
as thick paper, cardboard or other suitable material or substance so as to prevent
breakage during transport or use.
:

page_text: Sometimes parts of the internal glass fittings may if preferred be united. together
by heat, in the manner understood by glass workers.
The mould and press in which my solid glass syphon head above set forth.is,
formed, may be: thus devised..
I take a suitable horizontal iron table or plate (preferably mounted on 'standards)
and on its upper side but near to one of its ends, fix an arched framework, having
a vertical central slide formed on it and on which slide a carriage is adapted to
travel in a vertical direction, and to such carriage is fixed the part hereinafter
described as the "pressure plunger." The vertical motion of the said. sliding;
carriage may be obtained by any of the methods adopted in connection with
glass-pressing devices.
On the upper side of the table (which is made level for that purpose) I fix two
dovetail vees or slide guides in the direction of its length such guides being a
suitable distance apart and extending under the above mentioned. framework and
slide carrying the "pressure plunger."
On the upper side of a rectangular iron box or saddle piece, which is arranged.
to slide steadily between the before mentioned guides; I fix an iron plate which
forms the foundation plate of the mould. Such plate has a central circular raised
portion, the edges of which are somewhat undercut or bevilled; and in the centre.
of. this circular part is a hole which is screwthreaded to the same diameter and
pitch of screw as the screwthread intended to be formed in the opening in the:
underside of my glass syphon-head. The lower part of the screwed hole in the
underside of the foundation plate is made large in order to receive a collar which
is upon a plunger hereinafter described, and fits the said hole.
The upper side of the circular raised part of the foundation plate will be
the underside, or bottom of that part of the mould, which shapes my improved.
syphon-head.
That part of the iron mould proper which will give the external shape to my
glass syphon-head is formed in halves, and adapted to open laterally upon a vertical-
hinge pin, one. end of which I prefer. to. fix in the before mentioned. foundation
plate.
The internal part of the mould is of the same shape as the exterior of the
syphon head to be formed therein by pressure, and its open lower-part is devised
to close tightly round and upon the circular raised and undercut. part of the
foundation plate, so that the mould may be kept central with such raised part.
Suitable catches are provided to keep the mould firmly closed whilst
in use.
7
Through one side of the foundation plate, a long metal plunger is devised to
pass at a suitable angle into the glass pressed into that cavity in the mould which
will shape the nozzle of the syphon head for the purpose of forming the longi-
tudinal aperture in the said nozzle, and at the opposite side of the, said mould
another plunger will be devised to pass into the glass pressed into the upper-part
of the head mould in order to form the slot or opening in the syphon head which,
will receive the end of the lever which operates the syphon valve.
Both plungers are operated by means of a suitable arrangement of levers or
other devices.
The vertical internal chambers in my improved syphon-head are forined by
means of an iron plunger, or core, of the same shape as such intended chambers!
and devised to work upward into the mould, through the central opening in the
circular raised part of the foundation plate. The screwthread on the plunger-is
continued a sufficient. distance above the top of the circular. raised part of the
foundation plate in. order to form the screwthread. in the inside of the glass
syphon-hend.
:
. ▸
The lower part of the plunger is provided with a collar, which fits into the
chambered opening in the underside of the foundation plate, and so regulates the
height.to. which the top of the plunger is intended to be raised in the mould.
'
In order to give the plunger the necessary rotative movement so as to enable

page_text: the screwed part upon it to be withdrawn from the plastic glass in the mould, I fit
upon the end of the plunger and below the collar, a bevelled or other suitable
cog-wheel, and to such wheel, I gear another which is fixed upon a shaft fitted with
a suitable hand wheel or crank, and by such means the plunger can be manipulated
as may be desired.
The extreme lower end of the plunger may also be steadied by means of a
bracket on the sliding saddle piece.
The top of the mould will be left open for the purpose of feeding the mould
with the hot plastic glass from the furnace and the "pressure plunger" herein-
before described will be devised to slide comfortably in such opening. Its lower
end will obviously be of such shape as will give the desired shape to the top of the
glass syphon head to be formed by pressure as set forth.
In operating the above described mould, it will be first drawn to the front of the
table and away from the " pressure plunger." The various plungers having been
placed in their respective proper positions, the mould is then closed and locked,
and its open upper part having been filled with the requisite quantity of molten
glass, the mould is immediately pushed back so as to come under the arched
framework and against a suitable stop, and the "pressure plunger" is then forced
down upon the molten. glass by which means it is evenly pressed and distributed
over the inside of the mould and round the plungers. Such plungers are then
immediately withdrawn and the mould can then be opened and the pressed glass
syphon-head removed therefrom as soon as the glass is sufficiently set.
Instead of the mould being open at the top and filled with molten glass upon
which the "pressure plunger" will operate as set forth, I sometimes prefer to close
the top of the mould leaving only a small aperture therein. I then fix an iron
reservoir to hold the molten glass over the top of the mould, which will have an
aperture devised to go over the small aperture formed in the top of the mould.
The "pressure plunger" will be arranged to press upon the mass of glass in the
reservoir and force sufficient of it through the apertures into the mould. When
sufficiently set, the glass head-piece will be broken off at the glass connecting piece
or "feeder" which filled the feeding hole or aperture.
In some cases I prefer to form the nozzle portion of my glass syphon head
separately and then fix it to the head by screwing or otherwise. In such case I
form the nozzle in a separate mould by pressure as above set forth.

COMPLETE SPECIFICATION.
Improvements in or connected with the Manufacture of Syphons
and Seltzogenes, or parts thereof, for Aërated Waters.
I, HENRY LOUIS PHILLIPS of 57 Moorgate Street in the City or London
Gentleman 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':―
My present invention relates to improvements in or connected with the manu-
facture of syphons, seltzogenes and the like, or parts thereof adapted for aërated
waters.
As is well known the vessels called syphons of tlie kind above referred to, cousist
of two separate principal portions, that is to say a body portion made of thick
glass for containing the carbonated liquid (generally called the vase or container)
and a head-portion made from metal and attached by screwing to the neck of the
vase such.head-portion having a nozzle opening through which under considerable
pressure the syphon is filled and emptied; a lever which operates an internal valve
devised to open and close the syphon-tube; and such head-portion also containing a
spring, washer, and other:necessary. parts...

page_text: Hitherto the heads of all such syphons have been made or cast from metal
(generally lead or an alloy thereof) but the chemical reaction of carbonated or
acidulated waters upon such metal has been long recognized by medical men as
injurious to health. I am aware that efforts have been made to overcome that
objection by lining the metal syphon head, or such parts thereof as necessarily
come in contact with the carbonated liquid, with pieces of comparatively thin glass
tubing; but such separate pieces have to be first carefully put together and joined
by means of the application of fire and skilled labour, and the metal alloy which
forms the syphon-head is then melted and cast over the thin glass tubing. Apart
from the cost of the metal, this process is found to be slow, troublesome, and
expensive, owing to the care required in putting the various parts together in the
first instance, and to the considerable amount of glass tubing destroyed during the
operation of covering it with the hot metal.
My present novel invention has for its main object the forming the head-piece of
the syphon for the purposes set forth, entirely from glass, so that the carbonated
liquid in its passage through such glass head-piece into and out of the syphon or
vase, cannot be poisoned or contaminated by contact with any metal whatsoever.
By such novel device, I not only dispense with the use of metal in the construction
of the syphon head; but by the means hereinafter set forth and shown, I materially
lessen the cost of its manufacture, and at the same time produce a perfectly
unobjectionable article..
Into the interior of my novel glass syphon-head (which head is formed from
plastic glass by moulding and pressing, substantially as hereinafter illustrated) I
insert fit and arrange certain novel devices hereinafter fully described, which form
part of my present novel invention, and as will be seen hereafter, the central interior
portion of my improved syphon-head is suitably shaped or chambered, so as to
receive such devices.
I will now proceed to describe the features and method of constructing my
improved glass syphon-head, as well as the several parts or devices to be employed
in combination therewith. In order that such description may be more clearly
understood, I have hereto appended five sheets of drawings forming part of my
Specification to which I refer.
Figures 1. 2. 3. 4. 5 and 6 of such drawings are vertical sections through my
improved syphon-head and show various methods of constructing and combining the
separate internal parts of the same.
.
Figures 7 to 18 inclusive show details of separate parts.
Figures 4 and 19 show the ordinary screwed ring generally employed for attaching
the syphon-head to the vase.
Figure 4 shows a method of securing a syphon-head to the vase A. when neither
the head piece nor the neck of the vase have screwthreads formed in their substance.
In such figure, is shown the neck of the vase, such neck being plain, but having an
external circumferential bead thereon, the syphon-head is also provided with a
similar bead round its lower end. I then take a metal ring (formed in halves, such
as that of which Figure 19 is an illustration) with an outside screwthread, and.
place it round-the neck of the vase below the bead formed thereon. I then provide
an internally screw-threaded collar of greater but sufficient depth than that of the
ring and screw it over the parts of the screwed ring placed in position as aforesaid,
and so hold them together. I then take another ring formed in two halves, similar
to that placed round the neck of the vase and place such half portions in position
above the bead formed on the head, and then, whilst holding them together in place,
I screw such syphon-head by means of its screwed ring, down into the upper part
of the deep internally screwed outside collar already upon the neck of the vase, as
tightly as possible. When such method of fastening is employed, it obviously alters
the external shape of the head-piece and therefore I prefer to have the vase so
shaped above the bead described with a raised cylindrical portion set back from the
projecting bead, the upper part of which portion forms the seating on which the
washer arrangement is placed. Figure 4 shows such construction by which

page_text: means the chambers and are kept of the same height as the like chambers
shown in other figures and therefore available for the same separate parts.
Figure, 20 shows a glass syphon-head in vertical section as it leaves the mould
hereinafter, described, and before fitting up the interior. chambers and with any
of the separate parts herein mentioned; but I do not restrict myself to the precise
forms of such chambers as therein shown, nor to the external form of the top or
body portion of the syphon-head.
:
Figures 23 to 28 inclusive show the mould for forming the syphon-head, and also
the sliding carriage, pressure plunger and gearing immediately connected with the
operating the mould.
All the above figures are described as hereinafter appears.
The same letters of reference indicate corresponding parts in the various figures
of the drawings. The vase or body portion (as forming part of a complete syphon)
is shown at A in Figure 1 of the drawings.
Figure 1 of the drawings is a vertical section through the centre of the syphon.
(consisting of the vase or body portion, and the head portion) and shows one:
method of construction as follows:
The vase or body portion A, as shown in such figure, is provided at its upper
end, with an external screwthreaded neck i; upon which I prefer to place. a thin
correspondingly screwthreaded band, made from celluloid, pressed horn, or from
any other suitable substance or composition, so as to act as a suitable antifriction
medium between such screw on the neck of the glass vase and a corresponding
screw intended.to be formed in the lower opening of the glass syphon-head B to be
screwed thereto as hereinafter appears, and shown separately in Figure 20 of the
.drawings.
In Figures 1, 2, 3, 5 and 6, I show the neck of the vase and the syphon-head as
provided with screwthreads for the purposes set forth; but I sometimes prefer to
make the neck of the vase with simply a bead round it but the syphon-head
having a screw as commonly used, and shown in Figure 4, where they are held
together. by means of the ring shown therein, and separately in Figure 19..
fitted or
Figure 9
The syphon-head B is formed of glass pressed or moulded into shape when hot
and plastic by means of a press and suitable mould as hereinafter described. The
glass syphon-head is provided with a projecting nozzle or spout k of any desired
shape but having a central aperture; communicating with a chamber / formed in
the centre of the head B. Such chamber communicates by means of a glass
syphon tube with the interior of the vase containing the carbonated liquid.
Passing vertically downward through the chamber, and also through the glass
syphon tube c (which is of the diameter required and extends from the interior of
the syphon head to nearly the bottom of the vase) is a long glass rod a which
reaches nearly to the bottom of the tube. Such glass rod a, at its lower end is
preferably formed. with an enlarged portion and in a groove round it,
sprung an india-rubber' ring shown in section at g to act as a valve.
shows such glass rod a separately, and Figure 8 shows the syphon tube c separately.
The lower end of the tube is furnished with a flanged or bell shaped mouth, as
- shown at h, and the rubber ring ground the end of the glass rod.a is devised to
press, against the inside portion of such flanged mouth and thus form a joint, and so
prevent the liquid rising in the syphon tube e except when the glass rod and the
valve attached thereto are depressed by the lever C aforesaid. The upper end of
the syphon tube is also formed with an outwardly turned flange cand by means of
two suitable, washers (such as may, be made from sheet india rubber) placed over
and under such flange as shown at f, a suitable,soft elastic and air-tight seating will
be provided for the underside of the flange of the syphon tube upon the mouth of
the vase,,while, its, upper side will be also protected from injury, as shown in the
figure..
The upper.end portion of the glass valve rod'a is carried through the chamber!
formed in the syphon-head, into a smaller or upper chamber shown at ', and such
end is formed with an enlarged portion or head a round the underside of which is

page_text: nitted a sumciently thick rubber or other suitable washer e Such washer 13-
intended to be about the same diameter as the upper part of the larger or lower.
chamber against. which upper part it is devised to fit, and thus arranged, it serves
(in addition to acting as a spring in manner hereinafter described) to prevent the
liquid from penetrating into the upper chamber and escaping past the inuer end.
of the lever C when the syphon is being filled or emptied.
In order to support the rubber washer e in its proper position immediately under
the head a' of the glass valve rod as described, I place in the lower chamber / a.
somewhat short cylindrical piece, preferably of glass (such for instance as a short
piece of suitable glass tube) and shown at d (such short length of glass or other
tube is also shown separately both in plan and section in Figure 10). The upper-
end of such cylindrical piece d, if made from glass tubing after being sufficiently
heated,. is, by means of a suitable tool opened out or enlarged, as shown in
Figure 10, to the size of the diameter of the chamber 1, and its lower end is also
similarly enlarged, but has, in addition, a sufficient number of wave-shaped openings
formed in its edge portion as also shown in Figure 10 for the purpose hereinafter
described. Such wave-shaped end portion of the cylindrical piece is devised to
rest as shown, upon the inside part of the bell shaped portion formed at the upper
end of the syphon tube c, and it will be made of such length that when placed!
in position in the chamber its upper end will press sufficiently hard against the-
underside of the rubber washer e and thus hold it up in place as and for the
purposes set forth. To assist in preventing the rubber washer from being pulled
away from its place, the outer circumference of the roof or upper part of the-
chamber may be recessed or grooved as shown in some of the figures of the-
drawings and the edge of the washer will be then forced into such groove by
the end pressure of the cylindrical piece d.
.
When, and for such period, as the glass valve-rod a is kept depressed by means-
of the lever.C, the valve at the bottom of the tube will be opened and the liquid
rise and be discharged. When the pressure upon the lever is removed the-
washer e which also acts as a spring, will immediately rebound, and lift the glass.
roda and thus close the valve g, the pressure of the liquid contents upon the
valve further assisting to make the joint tight.
1
The body of the cylindrical piece d described, will be formed of such external
diameter that when inserted into the chamber it will leave an annular space-
between it and the wall of the chamber as shown in the figure. The external
opening in the nozzle is devised to open into and communicate with the chamber-
or such annular space therein. The wave-shaped edge of the short cylindrical
piece d is intended to allow of the free passage of the liquid from the syphon-tube.
into such chamber or annular space in the following manner:
When the valve g is opened, owing to the depression of the glass valve-rod
through pressure upon the lever by the operator as above set forth, the liquid will
rise through the syphon tube c flow round the base of the cylindrical piece d, and
by means of the wave-shaped, openings in the edge thereof, will enter the annular-
shaped portion of the chamber and thence be discharged through the nozzle
opening.
°
'
It will be evident that as the edge of the lower end of the cylindrical piece d'
is wave-shaped, it can only touch the syphon-tube in parts of, and not at the whole
of its circumference, therefore, in discharging the syphon the passage of the
liquid from the inside to the outside the piece d is not impeded. I do not.
restrict myself to such wave-shaped form of the edge. In some cases as when
required to keep in place a washer or the like in a syphon-head, and to save the
trouble of forming an annular recess to hold it therein, I also employ a cylindrical
piece (such as glass tube) which when inserted in place its lower end will rest upon
the rubber washer, such cylindrical piece being shown in Figure 15* of the drawing..
The description herein refers to the method of discharging liquid from the vessel
which will be filled in the usual manner.
One end passes.
The lever by which the valve rod is depressed is shown at C.

page_text: through a lateral opening m made in the upper part of the syphon-head which
opening communicates with the upper chamber l'. Such end crosses that chamber
and is supported in a recess formed in the opposite wall as shown. That portion
of the lever which remains in the chamber is curved at its underside as shown,
and such curved part is devised to rest upon the surface of a short piece n
(preferably made from a piece of glass rod) which serves as a distance piece between
the top of the glass valve-rod a, and the curved underside portion of the lever C.
The piece n may if desired be also made from celluloid, bone, horn, or other
unobjectionable substances.
The lateral opening m in the syphon-head is formed up to the point where it
opens into the chamber, just so much deeper than the depth of the deepest part of
the lever which passes through it, as will enable the lever to be therein freely
inserted and also allow of space for being sufficiently depressed by the hand of
the operator for the purposes set forth.
In some cases, I prefer to dispense with the short distance piece n, and I then
bring the curved part of the lever directly upon the end a¹ of the glass rod, and
thus correspondingly reduce the height of the syphon-head B or increase the length
of the rod. My object in keeping the upper chamber / somewhat high is to allow
of the same pattern and size of syphon-head shown in Figure 1, to be used, if
desired, with an ordinary metal spiral spring as and for the purpose shown in
section in Figures 5 and 6 of the drawings.
The enlarged portion a' at the upper end of the glass valve-rod, is made of such
size as to pass freely through the interior of the cylindrical piece d when fitting
the various parts together. The flange or bell-mouth shaped portion at the lower
end of the syphon tube e must also be made sufficiently small as to allow of it
being passed through the mouth of the vase A.
In putting together the various parts which constitute my novel invention, the
glass valve-rod a (having first had the india-rubber ring 7 stretched upon its lower
enlarged end b) is pushed through the syphon tube c, from its lower end h, and
when the upper end of the rod a has come through the flanged upper end of the
syphon tube, the short cylindrical piece d is slipped over it with its wave-shaped
edge portion next to the mouth of the syphon tube c, and then the india-rubber
washere is sprung over and upon the end a' of the glass valve-rod. The glass
syphon tube c is then dropped into place in the vase A the lower of the two rubber
rings or washers f, having been first placed upon the mouth of the vase.
The upper of the two elastic washers having been placed on the flanged top
of the syphon tube, and the circular distance piece n having been inserted into its
place in the chamber of my novel syphon head B (into which the lever C is already
inserted in the manner herein described and shown and the thin screw threaded
ring being in position) the head piece B will be dropped over the screw threaded
neck of the vase A and screwed tightly thereto, and thereby bind the various
parts firmly together.
It will be noticed that the lever C is prevented from falling out of the opening m
(when the internal parts are in position as described above) by means of the small
raised part on the upper side of the lever being caused to press against the side
of the chamber immediately above the place where the passage m opens into the
chamber.
The various flanges, enlarged portions, and the like, to be formed on the tubes,
valve-rods and other portions made of glass as herein described and shown will be
readily formed by means of the application of heat and such tools and appliances
as may be used by glass workers.
In some instances instead of placing the valve g at the bottom of the syphon-tube
as described, I prefer to place it in the syphon-head, and Figure 2 of the drawings
shows such alternative method of construction. In such case the vase A and the
glass head-piece B are of the same shape already shown in Figure 1; but the
syphon tube c in Figure 2 is left plain at its lower end as shown separately in
Figure 12 of the drawings.

page_text: Instead of only two rubber washers (as shown at in Figure 1) I; in this
alternative form, prefer to employ three, of suitable thickness (placed as shown at f
in Figure 2).
Resting upon the central rubber washer f placed on the top of the flange cof
the syphon tube, is a conical disc-shapedi piece o (shown separately' in Figure 1·1).
Such piece is preferably made from glass and forms a' seating; against the under-
side of which the rubber valve'g on the bottom of the valve rod a is devised to
press. The glass valve rod'a, and its upper part' a! (shown also in Figure 13) will
be similar in form with that shown in Figure'l except that it' will be very much
shorter. The action will of course be the same, that is to say, when the short
valve rod a is depressed by means of the hand' lever Cas already described, the
liquid in the syphon will risc.in the tube c go past the valve, packing g, through the
central' opening in the glass disco; through the wave shaped edge portion of
the piece already described; and then be discharged through the nozzle as shown
in Figure 1. The cylindrical piece d' is already shown in Figure 10 of the
drawings.
: :
A slight modification of the method of construction above described and illustrated
in Figure 2, is shown in Figure 6' of the drawings, wherein,, instead of forming
the seating for the rubber valve g upon or in the separate piece o and shown fitted
in Figure 2, the lower part of the already described cylindrical piece'd is: so much
expanded or made of a bell-month shape as to form a seating against' which the
valve will be devised to press; but instead of such edge being made of a waved-
shape (as shown in Figures 1, 2, and '10) it is formed witli a plain edge as shown
separately at Figure 7, and to prevent leakage past the edge of its mouth the upper'
of the two rubber washers is devised to press against the bell-shaped edge and
thus make a tight joint'as sliown in Figure 6 of the drawings.
To allow the liquid which rises in the interior of the cylindrical piece d (when
the valve roda is depressed by the lever as already described) to find its way, to.
the annular chamber and then through the nozzle opening, I make one or more
circular openings of sufficient size in any desired manner through the sides of the
pieced in any parallel part of its length, such openings furnishing the necessary.
means of communication between the inside and the outside of the said! pièce as
shown in plan and section in Figure 7.
The upper part of the valve rod a in Figure 6, instead of terminating immediately
above the spring washer'e as already described is sometimes continued a sufficient
distance upward (as therein shown) and terminates in a small enlarged portion'a
upon which the curved underside of the lever C is devised to rest: Roind the
upper part of the rod a a spiral spring q is fitted' as shown, its interior diameter
being greater than the diameter of the enlargement a' in order that it may be.
freely passed over it. Such spiral spring is intended' to keep the valve packing
ring g more tightly pressed. against. its seating; but in order to enable it' to lift or
press upward on the valve rod a, a collar or washer which may be made in, two
parts, is fitted upon the rod 'a; close under the head a' and against such collar the
upper end of the spring will press, whilst its: lower end will rest on a similar/
collar or washers which is pressed against the upper part of the chamber I by 'the
rubber packing disc e which holds it in its place, and thus prevents the liquid from:
reaching the spring. The lower washer will be made of the same diameter as:
the top of the chamber. The valve and. short glass rod are shown separately in!
Figure 16 of the drawings with the Halves of the split' collars rand's at some
distance from the side thereof:
"
The collars and's are shown more fully in Figure 18 of the drawings and again
in a modified form in Figure. 17, where instead of the collar being in two pieces it'
is shown in one piece, with a slot' or opening cut' through from one side to the
central'hole; so that it may be easily slipped over" the glass rod a. Such collars:
may be made from bone or other suitable substance. I do not however confine
myself to the particular shapes shown, as they may if desired be made in one
piece, and the valve-rod a may have the enlargement a" attached to it by screwing'
B

page_text: or otherwise, in which case it may be made. sufficiently large to act in place of the
collar 7.
Another modification of the method of constructing my improved syphon is
shown in Figure 5 of the drawings by which it will be seen the construction is
similar to that shown in Figure 6 except that the glass rod a instead of being
short (with the valve 9 contained in the syphon-head) is carried down to the
bottom of the syphon tube c, and the valve fitted at that point as already shown in
Figure 1 and such tube c and long rod a being shown in Figures 8 and 9 respectively
of the drawings. Figures 17 and 18 also show the upper part of the valve rod a
required for this purpose, the spring and other internal parts of the head including
the pieced being the same as already described and shown in Figure 6 of the
drawing.
Sometimes instead of a metal spring as shown at 7 in Figures 5 and 6, I employ
a short cylindrical block of india rubber, as a spring. It will have a central hole
devised to receive the upper end of the rod a and its lower end will rest upon the
washer and its upper end will press against the washer which supports the
head a¹ of the rod a. Figure 22 shows the application of the rubber spring at q
which is shown separately at Figure 21 of the drawings.
Figure 3 of the drawing is the same as Figure 5; but does not show the valve
rod a, the spring 9 or the collars and s, in position nor the lever C; but the
piece d shown in Figure 3 can be used in the construction of the syphon head
shown in Figures 1 and 2 (in place of the piece d. shown in those last mentioned
figures) if desired. Figure 3 shows at the nozzle collar or ring hereinafter
described.
Figure 4 of the drawing shows a syphon-head B, but with a. differently shaped
cylindrical piece d. The piece,d in such illustration is quite straight, and to effect
the required communication between its inside and the nozzle a hole is made
through its side to come opposite the upper end of the nozzle opening. The piece
is shown more clearly in Figure 15 of the drawings. Figure 4 also shows a method
of attaching the head B to the vase A referred to below.
The method of attaching the head B to the neck of the vase A shown in Figure 4
is the same as that generally employed with syphons, that is to say, the upper or
neck portion of the vase A instead of being formed with a screw thread has only a
plain collar or bead formed round it as shown, and found the neck of the vase, and
immediately under such collar is fitted an externally screw threaded collar or ring u
(shown also in Figure 19). Such collar is made in halves so as to enable it to be
placed round the neck of the vase and under the collar, and it may be of any suitable
substance such as metal, horn, celluloid, and the like, and it is kept together and in
place, by the head B being screwed down over it, the screw in the inside of such
head being devised to fit the screw thread formed on the outside of the collar or
ring.described.
:
It will be evident that in forming a glass syphon-head by means of moulding and
pressing, that the plunger of the mould which is devised to form, internal chambers
(such as 1 and 2) must be. of taper shape so as to be capable of being withdrawn
from the plastic glass, hence necessitating gradual diminution of the diameters of the
several chambers as shown and therefore rendering it impossible to form grooves or
ledges therein. The several separate parts described to be placed therein must be
inserted from the lower open end, and to provide the necessary internal circular
ledge or artificial contraction by which the working internal parts are, held up in
their respective proper positions, I employ the cylindrical piece which is shown at d
in several of the figures of the drawings and separately in Figures 7, 10, 14, and 15
and insert the same into an inner chamber as already described and shown.
I sometimes in addition use such piece as a suitable valve seating as shown in
Figures 6 and 22. The figures of such piece d are only given by way of illustration
in the drawings therefore so long as such objects or any of them are achieved with--
out interfering with other requirements the form of such piece may be varied as
desired, and therefore in referring in this Specification to such piece d it is to be

page_text: understood that unless the particular form of the said piece d is described, that any
other form whatsoever which answers the purpose intended may be used without
departing from the scope of my present invention.
The glass nozzle may be protected by an external metal collar or band of any
desired width and shape, and such collar may be fitted into a circumferential
depression of corresponding width formed on the nozzle as shown in dotted lines at t
in Figure 3.
The collar may sometimes be made as a thimble having an opening in its end,
and so attached as to protect the point of the nozzle. Sometimes I protect the
glass nozzles with sleeves or covers of cheap material or substance such as thick
paper, cardboard, millboard or the like to prevent it being damaged during transport
or use. Such covers may be devised to protect the head as well as the nozzle, and.
I generally prefer to form such protection covers of any shape by stamping them
by means of dies or tools operated by a suitable press from thin sheet metal, or
metal plate, such as ordinary tinned iron or steel plate. They may be made to fit
the glass syphon-head and protect if desired the lever as well as the nozzle ; but I.
do not give any drawings in illustration thereof as suitable shapes will readily
suggest themselves.
I do not confine myself to having the internal parts as shown herein made in
separate parts as described, as it is quite possible to join some of them together,
(such for instance, the syphon-tube c, and the piece d in Figures 1, 3, 4, 5 and 6) by
the application of heat, and suitable glass workers tools; or the three separate
pieces c, d, and o in Figure 2 may be joined together, or either of them as desired.
The piece n also may be joined to the knob a' or it may be formed in one piece with.
it, without departing from the spirit of my invention.
The drawings annexed hereto, as well as the several figures thereof, are not to be;
taken as exhaustive of the different combinations which may be made of the various
parts of my novel invention, but only as illustrative thereof. For instance, the
arrangement of the short valve-rod a with the piece n, and the rubber washer e as
shown in Figure 2, may be used in combination with the valve g, the cylindrical
piece d, and the syphon tube e as shown in Figure 6 of the drawing.
The nozzle shown in some of the figures of the drawings may be made shorter
and of a shape different to that shown.
It being impossible to describe all the combinations which may be made,
and claimed, by interchanging and combining the various separate parts herein
described with each other, I will only give one form illustrative of what I
consider to be a generally useful combination of parts for the purposes set
forth. Such a combination is illustrated in Figure 22 of the drawings, wherein
I show the glass syphon head B with nozzle opening j, lever opening m lever C
rubber spring washers r and s, washer e, cylindrical piece d short rod a having
enlarged portion a¹ and rubber valve upon its enlarged lower portion b, two
washers syphon tube c and flange c', all of which parts are combined with a vase,
the neck portion only of which is shown marked A in the figure.

As my novel method for making syphon-heads from hot molten glass by pressure,
requires to be accomplished with the utmost speed, I have devised a special form of
mould and plunger therefor, so that the external and internal portions as well as the
required openings in the syphon-head may be formed practically simultaneously,
such mould with novel devices to operate the same are described below and
illustrated in the several figures on Sheets 4 and 5 of the drawings. Like letters of
reference relating to such mould and devices are used in different views of the same
parts shown on such two sheets. The drawings of the mould and parts described
are given only by way of illustration of my invention.
I will first describe the form of press employed to press the plastic glass in the
mould. Upon the surface of a sufficiently thick and smooth horizontal iron plate
of rectangular shape and preferably mounted upon standards (so as to form a flat
and rigid iron table) but near to one of its ends, I fix an arched framework, having
:

page_text: a vertical central slide formed upon it, in or upon which a. carriage is devised to
travel in a vertical direction but none of such parts are shown in the figures
being already well known to glass workers. To such carriage is fixed by bolts or
otherwise that part herein described as the pressure plunger and shown.at A.in
Figure 23 of the drawing, such pressure plunger. being suitably shaped at its
lower end so as to enter into the upper part of the mould J, press the plastic
glass therein, and complete the formation of the syphon-head. The vertical.
motion of such sliding carriage will be obtained by any of the methods usually
adopted in connection with glass-pressing devices.
Figure 23 is a representation of a vertical transverse section through the centre
line of the mould; and of a saddle-piece which is hereafter described and it shows
the various plungers applicable to any method of working such mould.. The
figure also illustrates devices for automatically controlling, the plungers and
locking of the mould (with the exception of the withdrawal of the plunger 0)
and such devices are hereinafter set forth. I will now however first proceed to
describe the ordinary method of operating the mould manually. Such figures of
reference in Figure 23-as are not referred to in the following description of the
manual method of operating the mould and its plungers are to be taken as not
belonging to such description, but belonging to the description which hereinafter
refers to the automatic method.
.
To the surface of the table above mentioned I secure by bolts an iron
rectangular plate B of suitable thickness, upon which in the direction of its length.
I fix two dovetail vees, or slide guides C such guides being placed parallel to each
other a suitable distance apart, and extending from one end of the table to the
other or thereabouts and passing under the above mentioned framework and the
slide which carries the pressure plunger.
On the upper side of a rectangular iron saddle piece shown at D devised to
slide steadily between the aforesaid guides C I fix by means of bolts an iron
plate E which will form the foundation plate of the mould. Such plate has a
central circular raised portion F the edges of which raised portion are somewhat
undercut or bevilled for the purpose below, set forth and in its centre is a sufficiently
large circular opening having a screw thread formed therein of the same size and
pitch of thread as that which (by means of the screw threaded iron plunger H
described below and devised to operate therein) is intended to be formed in the
opening in the lower part of my glass syphon head hereinbefore described. Such
screw thread will be made to extend about half-way through the thickness of the
foundation plate E.
The lower part of the partly screwthreaded opening in the foundation plate E
is made plain and somewhat large for the purpose of receiving a collar G formed
upon the plunger H. and devised to operate in.such.opening..
1.
:
The surface of the circular raised portion F of the foundation plate will form
the bottom portion of my glass syphon-head the shape of which will be that of
the space in the figure of the mould left white and shown at I in the drawing.
That part of the inould J which will give the greater portion of the external
shape to my syphon head is formed preferably in two portions, and devised to be
attached to, and to open. laterally upon a vertical hinge K, the pin L of which
hinge, fix firmly in the foundation plate E as shown in the drawing. The
junction line of the two halves of the mould will extend through the centre of the
nozzle. My object in bolting the halves of the mould to a separate portion which
forms the hinge is to facilitate the letting together of the faces of the mould as the
edges of the opening may become burnt away or worn.
The internal part of the mould is so formed as to give. the greater portion of the
desired external shape of the glass syphon head to be formed therein, by pressure,
and the lower part of such mould is adapted to close tightly upon and round the
circular raised and undercut part F. of the foundation plate, and so keep the mould
central with the said raised part.

page_text: a surcatore eaten or locking Dar M is provided to keep the mould firmly closed,
whilst the plastic glass is in it, and pressure is being applied thereto by means of
the pressure plunger A.
Through one side of the foundation plate a long metal plunger N is devised to-
operate at a suitable angle and to enter into that part of the cavity of the mould
which shapes the nozzle of the syphon-head, for the purpose of forming the
longitudinal aperture therein by which the syphon is filled and emptied. "That.
part of the surface of the foundation plate through which the plunger N passes,.
is preferably so formed as to be at right angles with the plunger, and the mould is.
correspondingly shaped to fit it, so as to make a good joint. At the opposite side.
of the said mould, another plunger will be devised to operate and to enter the
upper part of the cavity in the mould, where it is desired to form the slot or
opening in the glass syphon-head which receives the end of the lever. Such
plunger owing to its relative position with that of the nozzle is devised to pass
freely through the hinge piece K and mould J, but that part of the passage which
is formed in the hinge-piece K and wall of the mould J, is formed as to one half
of it, in one half-portion of K and J, and as to the other half of it in, the other
half-portion of K and J. The, back of the hinge-piece K is suitably channelled*
or widened out, so as to prevent it from pressing or binding upon the plunger O.
when the mould is opened.
Figure 28 is a small plan showing the two halves of the mould J partly open,.
and the position of the passage in dotted lines. K shows the hinge-portion with
bolts, and the passage through it in dotted lines, and also the channelled or
widened out portion. L shows the pin with the passage in dotted lines through it,.
to receive the plunger which is shown in position at 8. The notched locking-bar
is shown at M on the right hand half of Figure 28, and the pin, over which it.
locks, is shown on the left hand half of the same figure.
Continuing my reference to Figure 23 it will be seen that the two vertical
internal chambers of my improved syphon-head are formed by means of the upper
end of the lower plunger H, which will be of the same shape as such chambers, and
sufficiently taper so as to be readily withdrawn from the plastic glass after pressure.
The plunger H is devised to work upward the required distance through the central
opening in the circular raised part F of the foundation plate described. In order
to form a screw thread in the lower part of the central opening in the glass syphou-
head as described herein, a screwthread of the required shape and pitch of thread
is formed or cut upon the lower part of the plunger H and is of such length as to
extend a short but sufficient distance above the surface of the circular raised part.
of the foundation plate when the plunger is fixed in position to receive the plastic.
glass about to be pressed.
The lower part of the plunger is provided with a collar G devised to fit into au
opening formed in the underside of the foundation plate E, by which means the
height to which the top of the plunger is intended to be raised in the mould may
be regulated. As the plastic glass will be pressed round the screwthread formed
upon the plunger when in the mould, such plunger must rotate so as to enable its.
screwthreaded part to be disengaged and withdrawn from the plastic glass. For
such purpose I place underneath the top portion of the saddle piece 1) a toothed
bevelled wheel P through which the lower end of the plunger H will slide freely,
but in which it is prevented from rotating by means of a feather or key (shown at
in Figure 27). The bevelled wheel P is retained in its proper position by the
plate secured by screws to the saddle piece D. The lower end of the plunger H
is kept steady by a bracket W fastened to the saddle piece. To such wheel P,
I gear another bevelled toothed wheel which is fixed on the end portion of a shaft
the axis of which is parallel with the two slides C. Such shaft is supported on
brackets bolted to the saddle piece and its outer end is fitted with a hand-wheel or
cranked handle. By turning such wheel or handle, the operator can cause the
plunger H to enter or withdraw from the mould as desired.
The nozzle plunger N will be pivoted at its outer end below the foundation plate

page_text: to a lever, one end of which lever may be fastened to a suitable bracket fixed
on the side of the saddle piece D and the other end be provided with a suitable
handle and a catch for retaining the lever in any desired position.
The plunger O will be operated by means of a lever to which its outer end is
pivoted centrally or thereabouts and the lower end of the lever will be pivoted to a
bracket fixed on the side of the saddle piece D below the plunger O. The upper
end of the lever will be fitted with a handle, and a suitable catch will be placed on
it for retaining it in any position desired.
The top of the mould will be left open for the purpose of feeding it with the hot
plastic glass from the furnace, and the pressure plunger A herein before described,
will be devised to slide freely up and down in such opening. The lower end of the
plunger which comes in contact with the glass, will obviously be of such shape as
will give any desired shape or finish to the top of the syphon-head to be formed by
pressure in the mould as set forth.
The levers, wheels, or other means for manually working the plungers H, N
and are not shown in the drawings, except the wheel P which operates the
plunger H.
In manually operating the above described mould, it will, with the saddle-piece D,
attached, be first drawn away from the pressure plunger A (which will be lifted for
such purpose) to the front part of the table already described, and the several other
plungers above set forth, will, by means of the levers and hand wheel, or cranked
handle, be then placed in their respective proper positions and there secured and
the mould closed and locked, preferably by means of the locking bar shown in the
drawing. A sufficient quantity of hot molten glass from the furnace will be placed
through the top opening into the mould which will be then immediately pushed
back against a suitable stop on the surface of plate B, so as to come into
proper position under the arched framework, and the, slide, which carries the
pressure plunger.
The pressure plunger which will be operated in the manner customary with glass
workers, will then be forced down through such open part of the mould upon the
molten glass, which will be thus evenly pressed and distributed over the inside of
the mould, and round about the other several plungers. All the plungers will be
then withdrawn the mould be opened; and the glass syphon head be removed
therefrom and annealed in the customary manner.
The foregoing description relates to working the mould and plungers manually;
but as workmen are sometimes careless, and it is necessary to commence removing
the plungers from the newly-pressed head-picce, before the glass shall have
contracted on the plungers and thus become "crizzled " I prefer to operate some
of the plungers by means of mechanical devices which are mainly automatic in
their action (and also illustrated in Figure 23) which I will now proceed to
describe.
To the toothed bevelled wheel P already described above, I gear another toothed
bevelled wheel which is shown at Q in Figure 23. Such wheel is fixed to, or is in
one piece with a pinion R, which rotates upon a stud S, fastened by bolts to the
inside of the sliding saddle piece D. The pinion R will be geared with a toothed
rack T, of a length sufficient to give the required number of revolutions to the
train of wheels already described, and through it, to the plunger H, when the
saddle piece D, and the parts attached thereto, are moved along the plate B. The
rack T is fixed down in a shallow groove formed in the surface of the rectangular
plate B, by means of screws or bolts, and has a slight amount of end movement
allowed it (for which object the screws which hold it down pass through slots) and
the object of such end movement will be hereafter described.
The nozzle plunger N, does not rotate, but is caused to slide in either direction
by means of the following device. The lower portion of such plunger is screw-
threaded for a sufficient part of its length, as shown in Figure 23 and slides in and
out of a tubular bracket X. The plunger is prevented from rotating by means of
a long slot made along the bracket and a pin fixed at the end of the plunger which

page_text: operates therein as shown at Y. The screwthreaded portion of the plunger N
slides freely into the foundation plate E as shown and placed upon the screw-
threaded part of the plunger, and between the edge of the foundation plate and a
bracket Z is an internally screwthreaded bevelled toothed wheel a which when
caused to rotate as hereinafter appears, will by means of its internal screwthread
acting upon the screwthreaded part of the plunger (which as seen is prevented from
turning) cause the smooth end of the plunger to slide into or out of the mould
according to the direction in which the wheel a is rotated. The bracket Z is
devised to keep such wheel in its proper position against the foundation plate,
when the wheel is being turned to force such sliding plunger into the mould. I
prefer to recess both the foundation plate and the bracket so as to receive projecting
bosses formed on the wheel and so assist in keeping it steady.
The wheel a is caused to rotate in the following manner. Upon a stud screwed
in the side of the saddlepiece D is pivoted a bevelled toothed wheel c which gears
with the wheel a. Against the side of the wheel c is attached a pinion d which
gears with a toothed rack e. Such rack is screwed down in a shallow groove
formed in the surface of the slide C but in such manner as to permit of the
rack having a slight amount of end movement, and therefore the screws will be
passed through slots.
By means of such rack and the bevelled wheels connected therewith the
required movement will be given to the plunger N when the saddle picce D is-
moved along the table.
The upper end of the plunger N is accurately shaped so as to butt closely against
the side of the plunger H.
The racks T and are allowed the slight amount of end movement set forth in
order that after wear and tear of the working parts, they may be from time to time
set forward to compensate therefor.
The plunger O is operated in the following manner. The outer end of the
plunger is connected by means of a short link f to the upper end of a lever g
which is pivoted at between two strong brackets the lower end of the lever
works between those brackets and projects below them for a short but sufficient
distance. The inner edge of the lever is provided with a strong spring j the free
end of which presses against the side of the saddle-piece d and therefore tends to
keep the plunger O constantly in its inner working position.
Along the surface of, and for the greater part of the length of that slide C
which is next the lever is formed a raised ledge and the space between its
inner side, and the side of the saddle piece D, will be such as to just admit the
lower end of the lever when the upper end of such lever is pulled away by
the workman from the mould the required distance to withdraw the plunger O.
At a point in the length of the straight piece & corresponding with the position
which the end of the lever g is in, when the mould is directly under the
plunger A, I make a notch or recess into which the end of the lever g will be
forced by the spring j, at the same time that the upper end of the lever forces
the plunger O into the hollow part of the mould, and then through an opening
formed in the top of the plunger H as shown in the figure. A suitable ring or
handle for operating the lever g by the workman is shown at l.
Owing to the special construction of the end of the lever y as set forth, the
workman is compelled to withdraw the plunger O from the mould by means of
the ring in order to release the lower end of the lever g from the recess in
the piece and thereby enable him to bring the mould to the front of the
table, and in so doing operate the trains of wheels devised to withdraw the
plungers N and H:
The position of the lever when its lower end is disengaged from the notch in
the straight piece is shown in dotted lines in the figure, in which position the
mould will be free to move as set forth.
My reason for devising that the lever shall lock the mould in position until
such time as the plunger O shall have been withdrawn from it, is in order that

page_text: the workman shall not (by forgetting to first remove such plunger,, and inad-
vertently trying to draw the mould to the front of the table and so rotating
the plunger H) cause the plunger O to be bent or damaged at that point where it
passes through the top of the plunger H.

In my description of the mould above given I have described the bottom central
plunger Has having a screwthread formed thereon so as to form a screwthread in
the opening of the glass syphon-head for the purposes set forth; but if it should
be desired to form a plain instead of a screwthreaded headpiece, I make that part
of such plunger which projects into the mould of a plain circular form; but having
a sufficient portion of its lower part screwthreaded (and devised to operate in a
screwthread formed in the lower part of the mould) so as to enable the plunger H
by rotating it, to be operated better than if it were drawn out of the glass by a
straight pull.

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Clain In the construction of syphons, seltzogenes and like vessels for the
purposes described the novel method of avoiding metallic contamination of the
liquid by forming the separate head-piece of the vessel from plastic glass by means
of moulding and pressing devices adapted to form the exterior and interior shapes
required (including nozzle, lever. and bottom openings) substantially as hereinabove
set forth and a method of forming a glass head-piece illustrated by a suitable
device shown in Figures 23, 24, 25, 26, 27 and 28 of the drawings.
Claim 2. In the manufacture of syphons, seltzogenes and the like for the
purposes set forth the method of avoiding metallic contamination of the liquid by
forming the separate head-piece therefor from pressed and moulded glass, such
head-piece being formed with nozzle, lever and bottom openings and with one or
more internal chambers (devised to receive hold or support.a valve-rod carrying a
valve, a valve.seating, washers and other parts or connections) and such head-piece
being devised to fasten upon the neck of the vase or container by any suitable
means substantially as described herein and illustrated by a head-piece shown in
section in Figure 20 (and some other figures of the drawings) in which B is the
glass head-piece, & nozzle, j.nozzle opening, m' lever opening, internal chamber,
Z¹ upper chamber; such head-piece being also shown with a screw-threaded
.opening.
