PROVISIONAL SPECIFICATION.
Improvements in or connected with Gasogenes or the like
for Preventing Bursting thereof.
I, FREDERICK THOMAS SNOW of the firm of Trew and Snow of 26 Basinghall Street
in the City of London Merchants do hereby declare the nature of this Invention (which
has been communicated to me from abroad by William Henry Foster of 100 Golden
Grove Terrace Darlington Road Darlington Sydney in the Colony of New South
Wales Ironmonger) to be as follows:-
:-
The object of this Invention is to provide gasogenes or the like such as bottles for
containing aërated waters with means whereby the bursting thereof is prevented.
For this purpose there is fitted to the gasogene or the like a valve of metal or
other suitable material. It consists of an outside collar attachable to the gasogene
or bottle in which collar a valve is placed so that it rests on a seat beneath. This
valve is preferably provided with wings or guides which enter slots in the interior of
the aforesaid collar or equivalent means for guiding the valve may be employed.
A spiral spring is placed on the valve and then a cap is secured on to the aforesaid
collar, which keeps the spring down and causes it to press the valve down to
its seat.
The valve has a fitting by which the usual syphon is secured to it.
The spring is tested to resist a lower pressure than that which would burst
the gasogene or the like and therefore on excess of pressure occurring surplus gas
can escape whilst sufficient gas for withdrawal of liquid by the syphon is retained
by the spring re-seating the valve when the dangerous pressure is reduced.

Improvements in or connected with Gasogenes or the like for
Preventing Bursting thereof.
I FREDERICK THOMAS SNOW of the firm of Trew & Snow of 26 Basinghall Street
in the City of London Merchants do hereby declare the nature of this invention
(which has been communicated to me from abroad by William Henry Foster of
100 Golden Grove Terrace Darlington Road Darlington Sydney in the Colony of
New South Wales Ironmonger) and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
The object of this Invention is to provide gasogenes or the like such as bottles
for containing aërated waters or liquids with means whereby the bursting thereof is
prevented. For this purpose there is fitted to the gasogene or the like a valve of
metal or other suitable material. It consists of an outside collar attachable to the
a seat
gasogene or bottle in which collar a valve is placed so that it rests on
beneath. This valve is preferably provided with wings or guides which enter slots
in the interior of the aforesaid collar or equivalent means for guiding the valve may
be employed. A spring is placed on the valve and then a cap is secured onto the
aforesaid collar which keeps the spring down and causes it to press the valve down to
its seat.
The valve has a fitting by which the usual syphon is secured to it.
The spring is tested to resist a lower pressure than that which would burst the
gasogene or the like and therefore on excess of pressure occurring surplus gas can
escape whilst sufficient gas for withdrawal of liquid by the syphon is retained by the
spring re-seating the valve when the dangerous pressure is reduced.

page_text: And in order that the said invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the accom-
panying drawings.
The drawings show the application of the invention to a gasogene from which its
analogous applications will also be understood.
Figure 1 is a vertical section of so much of a gasogene as is necessary to
illustrate this invention and Figures 2 and 3 are respectively an elevation and a plan
of the valve separately.
C
A is the upper part of the body of the gasogene to which is secured the collar B
by screwing it onto the ring a so that the packing c is forced onto the edge of the neck of
the gasogene to make a tight closure. The collar B is formed with a seat b on which
rests the ring d on the valve D) which is constituted by a cylinder with a flange as
shewn. On the flange, projections d² are formed which enter guides 62 in the upper
part of the collar B. Into the upper part of this valve the descending tube G and
outlet valve H (which may be of the ordinary or any suitable kind) are secured as
shewn. A spring E is placed on the upper side of the flange of the valve and is
confined by a cap piece screwed onto the upper end of the collar B.
When the pressure inside the gasogene exceeds that which the spring E can resist
the valve lifts and the gas escapes past the valve into the space above it and thence
passes through the space at for through a special orifice made
n the cap
piece and when the pressure is relieved the valve D is returned to its seat b
by the spring E.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In gasogenes or vessels for containing aërated waters or liquids a valve pressed
down with a pressure less than the bursting pressure of the gasogene or vessel so that
on a certain internal pressure being exceeded the valve opens to relieve the pressure
substantially as hereinbefore described.
2. In combination with the closure or drawing off device of a gasogene or the like
a valve pressed down to its seat by a spring so as to retain the gasogene or the like
closed until a given pressure is exceeded and then to automatically open to relieve
the pressure until the pressure is again reduced to the normal substantially as herein-
before described.
3. The combination of parts constituting the safety or relief device for gasogenes
or the like as hereinbefore described and illustrated by the accompanying
drawings.
