I, ARTHUR BERRIMAN 1 Morice Street Devonport Wholesale Confectioner do
hereby declare the nature of my invention for PREVENTING THE ESCAPE OF GAS
WHEN TAPS ARE LEFT ACCIDENTALLY OPEN to be as follows:-
An apparatus for preventing the escape of gas by means of the expansion &
contraction of atmospheric Air or Gas, consisting of a Tube with a Hollow Vessel at
one end and a flexible Bag or Box at the other end, working on a Pivot and fixed
over the Gas Bracket, so that the Hollow Vessel is suspended over the Gas Jet and
the flexible Bag or Box immediately underneath a fixed plate, a lever is attached to
this end of the tube which works a valve to shut the gas off or on.
I claim that when the Gas is not burning this apparatus will shut the Gas off and
prevent any escape, should the tap be left open.

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 :-
An apparatus for preventing the escape of Gas, worked by means of the expansion
and contraction of Atmospheric Air, or any kind of Gas or Liquid consisting of a
vessel (No. 1) connected by a Tube (No. 2) with another vessel (No. 3) one
portion of which is pliable or flexible. These are filled with Atmospheric Air, or any
kind of Gas or Liquid, and are fixed near a Gas light, so that the vessel (No. 1) is
over the Gas burner-A valve (No. 4) is fixed behind or below the burner. This
valve is regulated by the action of the pliable or flexible portion of the vessel
(No. 3) by means of a lever attached to the pliable or flexible portion of the vessel
(No. 3) with or without a spring.
When the Gas is burning the contents of the two vessels and the tube become
heated, and expanded and cause the pliable or flexible portion of the vessel (No. 3)
to project or to expand, which keeps open the valve (No. 4) and allows the Gas to
pass through it to the burner.
When the Gas is extinguished from any cause whatever, the contents of the
vessels and the tube cool and contract, and the pliable or flexible portion of the
vessel (No. 3) resumes its former shape and position, and thereby closes the valve
(No. 4) which shuts off the Gas from the burner, and prevents any escape should the
tap be left open.
In order to light the Gas, the valve (No. 4) must be opened and kept open until
the contents of the apparatus become sufficiently expanded to keep it open.
I wish it to be understood that I do not confine myself to any particular form or
shape of the apparatus herein described, as such may be modified without departing
from the essential features of my Invention.

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is
(1) As my Invention, the application and use of the expansion and contraction of
Atmospheric Air or any kind of Gas or Liquid, as a motive power to work an
apparatus for preventing the escape of Gas when Taps are left accidentally open.
(2) The application and use, (to contain the Air, Gases, or Liquids, by which the
motive power is obtained) of air tight Tubes or Vessels, one portion of which is
pliable or flexible or elastic, and by the action of which, the valve is opened or closed,
which turns on, or shuts off the Gas.
