Improvements in Syphons and Seltzogenes for Aerated Waters.
We THE GLASS LINED SYPHON COMPANY LIMITED, of Netherton Road,
Woodberry Town, in the County of Middlesex, Syphon & Seltzogene Manufac-
turers and HENRY JAMES NICOLE of the same place Manager for the said
Company do hereby declare the nature of this invention to be as follows:-
This invention has reference to improvements in the manufacture of syphons and
seltzogenes with glass linings to all the metallic parts, so that the aerated water is
prevented from contact with and consequent corrosion of the internal metal and
further to make the lining of the spout, of the body of the tap, of the valve
chamber and the dependent tube all of one piece and of glass. Or the dependent
tube may be separate and fitted by washer to the valve chamber.
The valve we prepare from india rubber deprived of evil taste and shaped
preferably as an elongated ball.
The glass lining we find it convenient to form of a tube of glass, shaped to the
interior of the spout desired and this we join into one with a tube which is to
form the lining of the body and having its bore at about a right angle to that of
the spout where it enters this body tube and the body tube is joined into one with
the valve chamber by blowing by which means also the valve chamber has also
been formed from the upper part of the tube.
The combined lining of glass thus formed is then laid in a suitable mould, say of
iron or other metal, and the metal or alloy, preferably tin to form the body of the
tap or head of the syphon seltzogene is cast thereon.

COMPLETE SPECIFICATION.
Improvements in Syphons and Seltzogenes for Aerated Waters.
We THE GLASS LINED SYPHON COMPANY LIMITED of Netherton Road,
Woodberry Town, in the County of Middlesex, Syphon and Seltzogene Manu-
facturers and HENRY JAMES NICOLE of the same place, Manager for the said
Company, 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 :-
This invention relates to improvements in syphons and seltzogenes for containing
acrated waters, in which the parts which come in contact with the aërated waters
are made of glass and non-metallic materials, and the object of the invention is to
line the composition, vulcanite or metallic parts of the head, tap or attachment to
the bottle which contains the parts which control the outflow of the aërated waters,
with glass in as nearly as possible, or convenient, one piece so as to reduce to a
minimum those parts which require to be packed.
We attain these objects by the mechanism illustrated in the accompanying
drawings, in which:
Fig. 1 is a vertical section through the middle of a syphon head attached to a
bottle, of which bottle the greater portion is omitted from the drawing it being of
ordinary construction.
Fig. 2 is an external view of the portion of a syphon shown by Fig. 1.

page_text: Fig. 3 shows separately the glass lining of the head or tap formed in one piece
with the syphon tube..
Fig. 4 is an exterior view of Fig. 3.
Fig. 5 shows separately the same lining as is shown by Fig. 3 with the exception
that the syphon tube is not formed in one piece with the glass of the head lining
but is butted against the trumpet mouth thereof, the ordinary packing serving to
prevent escape of gas or liquid.
Fig. 6 shows another form of lip to the mouth of the glass lining spout; i.e. a
bell-mouth or widened end to protect the metal from drip or this may be recurved
still more.
a indicates the glass lining of the head or tap parts of the syphon or
parts adjoining and coöperating a being that part lying within the spout or
delivery tube; that part lying within the neck or tube above the valve, and a³
that part that forms the trumpet mouthed seating for the valve ball b, and a
that part of the glass which either in one piece, or separately from the lining,
forms the syphon tube or eduction pipe for the water from the bottle, when by
the opening of the valve the internal pressure forces the water up that tube and
out by the spout a¹.
bis a stem which may be of bone or other suitable material furnished with a
knob at its lower end, here shown connected by screwing thereto. This stem
passes through a packing piece c, which resting on the upper edge of the part a²
of the glass lining prevents egress of liquid at that part.
On the upper end of this stem bis applied, say by screwing, a button 63, but
the form of this may be varied according to the form of the part of the lever d
which presses it down when pressure is applied to the end thereof d². d is the
fulcrum end of said lever which takes a bearing in a recess in the wall of the head.
e is the metal covering of the head, which metal is cast on the glass lining, leaving
the space e¹ in which is located the spiral spring, which spring rests on the
packing piece e as an abutment and presses up against the button so as to cause
the stem normally to keep the valve drawn tightly to its seating a³, e² is a slot
in the metal wall in which the lever a works.
g is a screw metal cap applied over the top of the hollow part e¹.
. is the portion of the ordinary glass syphon bottle to which the metal e is
connected in usual manner, here shown as by screwing, to a metal bushing i
correspondingly threaded, and cemented itself to the bottle.
Consequent upon the metallic or other parts of the head liable, by contact, to
foul the waters being isolated from the contained liquids, solvent action thereupon
is prevented, and danger of poisoning or contamination is avoided
We are aware that it has long ago been proposed to line syphons or seltzogenes
with porcelain and also with glass but such plans as have been published have
not been practically effectual, or have not been economically useful, and capable of
commercial utilisation.
The glass has been proposed to be used in pieces butted together, but contamina-
tion has still eventually resulted, whilst by our improvements this has been entirely
avoided.
The improved lining glass parts may be and are manufactured from tubing by
the aid of heat and the blow-pipe.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a head for a vessel containing aërated water a glass lining in one piece on
to which the head is applied by casting.
2. In a vessel for containing aerated water such as is known as a “ syphon,”
a head having a glass lining in one piece, in combination with a containing
bottle, and means for connecting the head thereto, and valve apparatus packed
suitably to control egress of the contained water.
3. A bead, valve apparatus and packings, and a containing bottle for aërated

page_text: water, in combination with a glass lining for said head, in one piece with the syphon
tube through which the aerated water finds its means of egress.
4. In a vessel for containing aerated water, a.head, valve apparatus and packings
therefor, in combination with a glass lining in one piece, said head being arranged
with the material of the shell thereof non-accessible to the contained water, as and
for the purposes set forth.
5. The various arrangements or combinations of parts of glass lined syphon
heads or seltzogene heads substantially as herein described and shown in the
drawings.
