PROVISIONAL SPECIFICATION.
An Improvement in Apparatus Used in the Manufacture of Aërated
Liquids.
HENRY THOMAS COOK of No. 3 Newport Road Northcote, Road Walthamstow
in the County of Essex Carpenter and Joiner do hereby declare the nature of this
invention to be as follows:--
This invention relates to an Automatic Valve for the prevention of Waste of Gas
upon removal or breakage of the bottle.
It consists of a Metal cup with end screwed for connecting to the Machine and a
piston working loosely through the centre having at the back end an india rubber
cushion for the closing of the Gas passage and a central passage for Gas half way
down centre of piston at which point it turns at right angles passing through
the side..
The action of above is as follows.-The bottle of liquid on being placed in the
Machine for Aerating presses down the piston thus leaving an opening for the passage
of Gas. The bottle on being taken out releases the piston and the India rubber
cushion immediately closes the valve by the back pressure of the Gas.

An Improvement in Apparatus Used in the Manufacture of Aerated
Liquids.
I HENRY THOMAS COOK of No. 2 Albert Terrace Westbury Road Walthamstow
in the County of Essex Carpenter and Joiner late of No. 3 Newport Road Northcote
Road Walthamstow in the said County 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 an Automatic Valve for prevention of waste of gas upon
removal or breakage of bottle.
It consists of a metal cup C. with one end screwed for connecting to the machine
and having a piston working loosely through See B this piston is screwed on the
outer end (for connection with a vulcanite valve and soft cushion of rubber upon
which the neck of bottle fits during process of Aerating) on the inside of piston is
a soft rubber washer (See A) which closes valve against passage of gas by shutting on
to the sharp edge of outer cup.
The action is as follows the bottle of liquid on being placed in the Machine for
Aerating presses down the piston (in which position it is shown in sketch) thus
leaving an opening for the passage of gas for half the length of piston round the sides
and for the remainder of the length passing through the centre thence into the bottle
upon taking out the bottle or upon breakage of same the piston is released and is
forced outward by pressure of gas until the rubber washer is pressed against sharp
edge of outer cup when the passage for gas is immediately closed.
Having now described the nature of the said Invention I wish it to be understood
that I do not confine myself to the precise details herein laid down as the same may
be varied without departing from the peculiar character of the Invention but what
is claimed and intended to be protected by the herein-in-part recited Letters
Patent is.
The combination of parts forming the improved valve for the apparatus or machine
for aerating liquids the whole arranged and operating substantially in the manner
and for the purposes hereinbefore described and illustrated in the accompanying
Drawing or any mere modification thereof.
Dated this 11th day of January 1887.
