Improvements in or applicable to Siphon Bottles and Seltzogenes.
I SAMUEL TAYLOR of Brookfield, Whalley Range Manchester in the County of
Lancaster, 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 :-
This invention relates to siphon bottles and seltzogenes for the storage and
manufacture of aerated liquids, the objects of the invention being to ensure perfect
cleanliness and purity, and to prevent the possibility of the liquid contents
coming into contact with any metallic substance, and thus causing corrosion or
galvanic action, and at the same time to obtain a gas and liquid tight valve and to
cheapen and simplify the manufacture of the heads of such siphon bottles and
seltzogenes.
The nature of my said invention and the manner in which the same is to be
performed will be readily understood on reference to the annexed sheet of drawings
and the following explanation thereof.
Fig. 1 is a front elevation of the upper part of a siphon bottle constructed
according to my invention.
Fig. 2 is a vertical section of the same taken through the centre of the nozzle
and Fig. 3 is also a vertical section but taken at an angle of about forty five degrees
to Fig. 2.
Fig. 4 is a similar view to Fig. 2 of the upper part of a seltzogene constructed
according to the same invention.
I make the removable top or head of the siphon bottle (see Figs. 1, 2 and 3) and
the spout or delivery nozzle both of one piece of moulded glass, and as in the
case of a siphon bottle no provision has to be made for the removal of the top or
head and delivery tube each time that the bottle has to be re-charged, I form the
glass top or head and I connect the same to the siphon bottle as hereinafter
described.
I form the top or head a and the nozzle a¹ of one piece of moulded glass, the
head being externally of cylindrical form, and of about the same diameter as the
mouth of the bottle b, the bore being cylindrical at the top, and coned out gradually
towards the bottom as shown at Figs. 2 and 3 to receive the upper part of a double
coned bush or hollow plug c of india rubber or other suitable substance.
This double coned bush or plug c performs three separate functions. In the
first place its upper surface (which I prefer to make of harder rubber than the
remainder) serves as a seating for the glass valve hereinafter described; secondly it
holds the glass delivery tube d firmly in its place, and thirdly it not only makes
a perfectly gas and liquid tight joint between the tube d and the removable
glass top or head a but also between the latter and the mouth of the bottle b.
The valve e I make of glass or other non-metallic material fitting loosely in the
upper or cylindrical part of the bore of the top or head a so that the valve shall
be able to rise and fall vertically its lower face being made with a central recess,
having a projecting rim all round which latter forms a gas-and-liquid tight joint on
being pressed down on the upper surface of the coned bush or hollow plug c.
Above the glass or other valve e is a disc or diaphragm g of india rubber or
other suitable elastic substance, the outer edge of which is held firmly between the
upper surface of the removable glass top or head a and a cap h hereinafter
described. This elastic disc or diaphragm makes a perfectly gas and liquid tight

page_text: joint above the valve e at the same time that it allows the valve to rise and fall as
required.
:
Above the elastic diaphragm g is a metal or other hard disci against which works
the point of a screw k'which screw passes through the centre, of the cap h and is
provided with a milled bead + or other means whereby it can be turned by hand
so as to screw down the valve e or release the same.
Attached to the cap or cover h by vertical bars is a complete metal ring or
band in placed below the spout or nozzle a' and having its lower part made with a
screw thread on the inside whereby the removable glass top or head a and the cap
or cover can be secured together and at the same time fixed onto the mouth of
the siphon bottle b, by screwing up the threaded ring or nut n which is divided.
vertically into two parts so that it can be placed round the neck of the bottle b
and united in the known manner.
It will be seen that the turning of this threaded ring or nut n not only fixes the
removable glass head a onto the mouth of the bottle but it also draws all the
parts firmly and solidly together thus making all the joints perfectly gas and
liquid tight.
The ring or band m covers the joint between the lower edge of the body a and
the mouth of the siphon bottle b.
In adapting my invention to a seltzogene (see Fig. 4) where it is necessary to
remove the glass top or head a with the delivery tube d each time that the vessel
is to be charged, I preferably make the coned bush or hollow plug c with a flange c+
instead of its lower coned part, and I fix by screwing, or otherwise, to the ring
or band m a cap o of a sufficient diameter to embrace the top 6 of the seltzogene
bottle, and I prefer to make the two halves of the divided ring or nut n with lugs
whereby the two parts can be united by screws p so that they virtually become
one solid ring which always remains on the neck of the bottle and is capable
of being turned round so as to couple the body a and bottle together and
uncouple the same.
The head a is not revolved but merely placed on the top of the bottle neck and
coupled or uncoupled by turning the screwed ring or nut n.
The outside of this ring may be milled or roughened or provided with pro-
jections or otherwise so formed on the exterior that it can readily be turned by
hand.
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 make
no general claim to the manufacture of the tops or heads of syphon bottles or
seltzogenes of moulded glass per se, nor do I claim separately any of the various
parts or details but what I claim is :-
In combination with the glass head of a siphon or seltzogene, a screw-down valve
made of glass or equivalent material provided with an elastic diaphragm and a
metal or other hard disc between the point of the screw and the top of the valve,,
a coned bush of india rubber or other suitable elastic substance so formed and
applied as to act at the same time as a seating to the glass valve, a gas and liquid
tight packing, and a holder for the glass discharge pipe, and a metallic cap or
cage for connecting the parts together and fixing them onto the bottle, all
respectively constructed attached and operating substantially in the manner and
for the purposes hereinbefore described and illustrated by the drawings annexed.
