Improvements in Apparatus for Manufacturing and Retaining
Aerated Liquids.
I, SAMSON BARNETT, of 1 Courtnay Terrace, West Brighton, do hereby declare
the nature of this invention to be as follows:-
This invention relates to the manufacture of aerated liquids by the addition to the
liquid of compressed and preferably liquefied carbonic acid gas.
For this purpose I form in the stopper of the bottle which is to contain the aerated
liquid a small chamber provided with a valve opening into the bottle and actuated
from the outside.
The bottle is filled with water or other liquid and the chamber in the stopper
with carbonic acid, the stopper is then secured in the bottle by screwing or otherwise-
and the valve is opened allowing the carbonic acid to escape into the bottle and.
impregnate the liquid.
Dated this 29th day of May 1896.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Manufacturing and Retaining
Aerated Liquids.
I, SAMSON BARNETT, of 1 Courtnay Terrace, West Brighton, 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 the manufacture of aerated liquids by the addition to the.
liquid of compressed and preferably liquefied carbonic acid gas.
For this purpose I form in the stopper of the bottle which is to contain the aerated
liquid a small chamber provided with a valve opening into the bottle and actuated
from the outside.
The bottle is filled with water or other liquid and the chamber in the stopper with.
carbonic acid, the stopper is then secured in the bottle by screwing or otherwise and
the valve is opened allowing the carbonic acid to escape into the bottle and impregnate.
the liquid.
Figure 1 shows a bottle fitted with a stopper made in accordance with this.
invention, the stopper a being in section and the chamber 6 in elevation. Figure 2
is a section of the chamber and Figure 3 an elevation of the stopper a.
In this arrangement the chamber 6 has a perforated screw stem b' screwing into
the stopper, its end coming against a seat at the bottom of the hollow in the stopper
thus making a gas tight joint. a' is an opening through the end of the stopper, and.
a is a screw thread on it. c is a packing ring.
To fill the chamber the stopper is screwed by the screw a² into the nozzle of the
compressed gas reservoir, the vessel b is then slightly unscrewed to uncover the.

page_text: opening at its end and allow it to fill and is then screwed home again. The charged
stopper is inserted into a bottle containing water or other liquid and the vessel b is
again slightly unscrewed to allow the gas to pass out at the end of its stem through
the opening a' into the liquid.
Other forms of valves and stoppers may be employed and the vessel b may be made
in one piece' with the stopper.
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. The combination of a stopper, a chamber in the stopper, a valve opening from
the chamber into the bottle, and means for operating the valve from the outside.
2. Apparatus for manufacturing and retaining, aerated liquids substantially as
described and shown in the drawings.
