PROVISIONAL SPECIFICATION.
Improvements in and connected with Syphon Bottles.
I, WILLIAM WALLACE SAVAGE, of 109 St. James's Street, Brighton, in the
County of Sussex, Chemist, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the construction of syphon bottles for containing
aerated waters, and its object is to do away with the present system of forcing the
liquids through the delivery spout, as such a process is objectionable, because of
the difficulty in properly cleansing them, and in order to overcome this difficulty the
syphon bottles are detached from the metal taps during the process of filling, and
will be stored in that condition until required for use, when the metal taps will be
screwed on to the bottle necks.
In carrying out my invention I provide an ordinary syphon having an externally
threaded neck, on which I screw an internally threaded metal tap; in the inside of
the neck, and at the bottom of the neck, I form a circular groove for the purpose
of receiving the flange of the syphon tube and the india rubber or other suitable
washers as hereinafter described.
The syphon tube which extends to near the bottom of the vessel in the usual
way, has a bell shaped top with a flange, which may be made either of glass or
metal; into this bell shaped top I place a glass ball, which when not in use as a
valve, will rest on projections that are placed, so that sufficient spaces are left for
the liquid to flow through.
On the flange of the syphon tube, and also below it, I have a ring made of
india rubber, cork or any other suitable material, and on the top of the flange I
place a similar ring of sufficient thickness having a hole in its centre which will
be closed by the glass ball, being held in position by the pressure of the liquid
within the syphon.
In carrying out my invention I place the flange of the syphon tube and the india
rubber or other suitable washers as described, into the groove in the neck of the
bottle, and this forms an air tight joint capable of resisting any pressure that is
usually applied in the filling of syphons. The metal tap that I use may be almost
of any construction, the only alteration that is necessary is, that the valve stem
below the seating should be tapered and of sufficient length to displace the glass ball
before the operation of screwing on the metal tap is completed, and preferably I
form the tapered valve stem with perforated holes and of such a thickness that the
hole in the top washer is not closed by its insertion but that ample space is left
all round for the liquid to escape.
It will be understood that it would be almost impossible to displace the glass
ball by depressing the lever of the metal tap, therefore it is, that that operation is
performed by the valve stem whilst the tap is being screwed on to the neck of the
syphon bottle.

COMPLETE SPECIFICATION.
Improvements in and connected with Syphon Bottles.
I, WILLIAM WALLACE SAVAGE, of 109 St. James's Street, Brighton, in the
County of Sussex, Chemist, 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 invention relates to the construction of syphon bottles for containing
aerated waters, and its object is to do away with the present system of filling the
bottles by forcing the liquid through the delivery spout, as such a process is
objectionable on account of the difficulty in properly cleansing them, and in order
to overcome this I so construct my syphon bottle that the metal tap is detached
during the process of filling and it is not necessary to apply it until the liquid is
required for use.
In order that my invention may be more readily understood reference is made to
the accompanying drawings which form part of this Specification and in which
Fig. 1 is a sectional view of a syphon shewing my improvements,
Fig. 2 is a section of the neck of the syphon shewing the top of the tube and the
glass ball forced against the ring,
Fig. 3 is a section of the neck of the syphon shewing the external thread for
receiving the metal tap and the internal groove for receiving the flange of the tube
and the india rubber or other rings and washers,
Fig. 4 is a plan of the bottom of syphon shewing the well hole.
In carrying out my invention I provide a syphon bottle having an externally
threaded neck A on which I screw an internally threaded metal tap E, at the
bottom of the neck and on the inside I form a circular groove B to receive the
flange of the syphon tube F and the rings or washers K and L.
The syphon tube F which extends to nearly the bottom of the vessel has a bell
shaped top with a flange made to rest in the groove B, into this bell shaped top I
place a glass ball H which when not in use as a valve will rest on slight projections N
which are placed in such positions as to allow the liquid to flow freely through.
Under the flange of the syphon tube F which rests in the groove B I place a
ring K and over the flange I place a thicker ring or washer L and this forms an
air tight joint capable of resisting any pressure that is usually applied in the filling
of syphons, and in order that the liquid cannot escape through the threaded neck,
place a similar ring on the top of the neck of syphon which is held tightly in
position by the metal tap; these rings may be made of india rubber, india rubber
faced with cork or any other suitable material.
The metal tap that I use may be almost of any construction, the only alteration
that is necessary is, that the valve stem O below the seating P is preferably
tapering and of sufficient length to displace the glass ball before the operation of
screwing on the metal tap is completed, to the bottom of the tapered valve stem is
attached a concave button C made to move freely round, and this coming in contact
first, with the glass ball, prevents the same from being scratched; if the ball should
by any means become scratched or damaged it would be impossible for it to fit
tightly against the ring L.
At the bottom of the syphon bottle and just under the tube I make a slight
hollow or well hole D so that the whole of the liquid can be obtained.
In the working of my invention I fill the syphon bottles in the same manner as
the glass stoppered bottles and the pressure of the liquid within forces the glass
ball against the rubber ring L; when it is required to be opened I take the
metal tap and screw it on to the neck of the syphon and before the operation is
finished the tapered valve stem O as before described will have displaced the glass
ball which cannot be forced back into the same position because the valve stem

page_text: extends below the rubber ring L, sufficient space being left between the valve stem
and the rubber ring L for the liquid to escape.
It will be understood that it would be almost impossible to displace the glass
ball by depressing the lever of the metal tap, therefore it is, that the operation is
performed by the valve stem whilst the metal tap is being screwed on to the neck
of the bottle.
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 I do not
lay any claim to the metal tap or to any modifications or alterations that may be
required to same in order to carry out my invention, but what I do claim is :-
1. The construction of syphon bottles having an externally threaded neck, and a
groove inside the neck, and the well hole at the bottom of syphon for the purposes
hereinbefore described and set forth and fully illustrated in the accompanying
drawings.
2. The employment of a tube in syphon bottles having a bell shaped top,
enclosing a glass ball, the flange on the top of the tube being formed to fit tightly
into the groove in the neck of the syphon by means of india rubber or other rings
for the purposes described and illustrated in the accompanying drawings.
