PROVISIONAL SPECIFICATION.
Improvements in Siphon Bottles for Containing Aerated Liquids.
We, JAMES KEMP WELCH, of Parkstone, Weybridge, in the County of Surrey,
Gentleman, and GEORGE BROWNEN, F.C.S. of Althorpe Road, Upper Tooting,
in the County of Surrey, do hereby declare the nature of this invention to be as
follows:-
In the Specification of a former Patent granted to us No. 5192 in the year 1889
we described a siphon bottle having a filling orifice at the bottom and at the top a
head with drawing off appliances. This siphon bottle head was so arranged that
the aerated liquid both in its exit and at other times was guarded from all contact
with metal. These features of our former invention we still retain whilst at the
same time improving the construction of the bottle head and the drawing off
appliances in connection therewith. The bottle head as we now construct it
consists of a glass cylinder with a delivery spout in one piece with it, projecting on
one side. The upper end of the glass cylinder has a screw thread moulded on it
either inside or outside and is closed by a corresponding screw plug cap or stopper
of vulcanite. Within the bottle head a solid disc of glass is contained; it is loose
and serves as a valve, closing against a shoulder within the bottle head and below
the junction with the spout. The vulcanite screw plug cap or stopper holds the
disc in gas tight contact with the shoulder until it is desired to draw off the liquid
and then it is unscrewed until it permits the glass disc to rise from its seat and to
pass above the entrance to the spout. To stop the outflow when desired the
vulcanite plug cap or stopper is screwed inwards until the disc valve is again
brought to its seat. The glass disc might be operated by a lever and spring or
other mechanism in place of a screw.
The glass cylinder forming the bottle head is secured at its lower end to the
siphon bottle by a screw collar of metal which surrounds the head and which
engages with a corresponding metal ring upon the top of the bottle.
Dated this 26th day of May 1893.

Improvements in Siphon Bottles for Containing Aerated Liquids.
We, JAMES KEMP WELCH, of Parkstone, Weybridge, in the County of Surrey,
Gentleman, and GEORGE BROWNEN, F.C.S., of Althorpe Road, Upper Tooting,
in the County of Surrey, 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 :—
In the Specification of a former Patent granted to us No. 5192 in the year 1889
we described a siphon bottle having a filling orifice at the bottom and at the top a
head with drawing off appliances. This siphon bottle head was so arranged that
the aerated liquid both in its exit and at other times was guarded from all contact
with metal. These features of our former invention we still retain whilst at the
same time improving the construction of the bottle head and the drawing off
appliances in connection therewith. The bottle head as we now construct it consists
of a glass cylinder with a delivery spout in one piece with it, projecting ou one side.

page_text: The upper end of the glass cylinder has a screw thread moulded on it either
inside or outside and is closed by a corresponding screw plug cap r stopper of
vulcanite. Within the bottle head a solid disc of glass is contained; it is loose as
serves as a valve, closing against a shoulder within the bottle head and below the
junction with the spout. The vulcanite screw plug cap or stopper holds the disc in
gas tight contact with the shoulder until it is desired to draw off the liquid and
then it is unscrewed until it permits the glass disc to rise from its seat and to pass
above the entrance to the spout. To stop the outflow when desired the vulcanite
plug cap or stopper is screwed inwards until the disc valve is again brought to its
seat. The glass disc might be operated by a lever and spring or other mechanism
in place of a screw.
The glass cylinder forming the bottle head is secured at its lower end to the
siphon bottle by a screw collar of metal which surrounds the head and which
engages with a corresponding metal ring upon the top of the bottle.
The drawings attached to this Specification show a siphon bottle made in
accordance with this invention.
Figure 1 is a section of part of a siphon bottle when the drawing off appliance
is shut.
Figure 2 is a section of the head of a siphon bottle when the drawing off
appliance is open.
A is the bottle head having a delivery spout B and a screw thread C moulded in
it. The screw plug D works in the screw thread C and regulates the movement
of the disc E. When the bottle is closed as is shown in Figure I the screw plug D
keeps the disc E in contact with a washer F¹ on the shoulder F. When it is
desired to open the bottle the screw plug D is unscrewed and the disc E is allowed
to rise into position shown in Figure 2. The screw plug D may be attached to the
disc E if desired.
The glass cylinder forming the bottle head A is secured to the siphon bottle by
a screw collar G which surrounds the head and which engages with the metal
ring H upon the top of the bottle.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is:-
1. The head of a siphon bottle consisting of a cylinder containing a disc which
is kept in contact with a shoulder within the head when the bottle is closed and is
allowed to rise when the bottle is open.
2. The head of a siphon bottle consisting of a cylinder containing a disc which
is kept in contact with a shoulder within the head by means of a screw plug
substantially as described.
3. A siphon bottle substantially as described and shown in the drawings.
