Improvements in Bottles for Containing Aerated Liquids and in
Apparatus for Filling the same.
1, DAVID GREEN, of 14 Charterhouse Square, in the City of London, Mineral
Water Manufacturer, do hereby declare the nature of this invention to be as
follows:-
:-
According to this invention I provide on the inside of the bottom of the bottle
a valve which is kept closed by the pressure of the liquid inside aided or not by a
spring. The object of this valve is to admit air into the bottle whilst it is being
emptied of the liquid bottled in it or of water which has been introduced for the
purpose of cleaning. It serves also to allow of the escape of air when the bottle
is being filled. In emptying the bottle the valve is raised from its seat by pressing
upon its spindle, which projects outside of the bottle, or it may be by a plunger
passing inwards from the outside. The filling machine is provided with a projection
which similarly opens the valve so that the air can escape through it. In order to
save the gas which passes out with the air a pipe is provided surrounding the
outlet, so that the gas is led to a gasometer from whence it can be pumped back
to the receiver. This pipe may be provided with a cock to the open air, so that
during the first part of the filling the air can be allowed to escape freely, but
usually the small quantity of air contained in the bottle will not be injurious and
it may be allowed to pass with the gas into the gasometer.

COMPLETE SPECIFICATION.
Improvements in Bottles for Containing Aerated Liquids and in
Apparatus for Filling the same.
I, DAVID GREEN of 14 Charterhouse Square in the City of London, Mineral Water
Manufacturer, 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 :-
According to this invention I provide on the inside of the bottom of the bottle a
valve which is kept closed by the pressure of the liquid inside, aided or not by a
spring. The object of this valve is to admit air into the bottle whilst it is being
emptied of the liquid bottled in it or of water which has been introduced for
the purpose of cleaning. It serves also to allow of the escape of air when the
bottle is being filled. In emptying the bottle the valve is raised from its seat by
pressing upon its spindle, which projects outside of the bottle, or it may be by a
plunger passing inwards from the outside. The filling machine is provided with_a
projection which similarly opens the valve so that the air can escape through it.
order to save the gas which passes, out with the air a pipe is provided surrounding
the outlet, so that the gas is led to a gasometer from whence it can be pumped back
to the receiver. This pipe may be provided with a cock to the open air, so that
during the first part of the filling the air can be allowed to escape freely, but usually
the small quantity of air contained in the bottle will not be injurious and it may be
allowed to pass with the gas into the gasometer.
In
In order that my said invention may be more fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation partly in section of a bottle constructed according to
my invention.
°
Figure 2 is an underside view of the same.
Figure 3 is a diagram view of an ordinary soda water bottling machine modified
according to my invention.
The bottle shown in Figure 1 is an ordinary globe-stopper soda water bottle but its
bottom is provided with a valve. This consists of a disc A faced with india rubber B
on the inside of the bottle, the stem C of the disc passing to the outside, and being
secured by a screw nut D. E is a washer of india rubber which serves as a con-
venient form of spring. F F are grooves cut on the outside of the bottom of the
bottle which allow the air readily to pass the washer E.
In Figure 3 the bottle is shown held mouth downwards between the cups G and H
which are of ordinary construction. The cup G however carries a spring plunger J,
which when the bottle is to be filled depressed onto the nut D thus opening the
valve allowing the air to escape from inside 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 what I
claim is
1. Bottles for containing aerated liquids having upon the inside of their bottoms
valves which are kept closed by the pressure of the liquid inside aided or not by
springs.
2. Bottles for containing aerated liquids substantially as described and shown in
the drawings.
3. Filling machines provided with a projection or plunger for opening the valve
substantially as described.
