Improvements in Gas and Water Taps.
ALBERT WILFRED COTTON, General Theatrical Manager, HowARD TALBOT,
Professor of Music, both of 3, Welbeck Mansions, Welbeck Street, London, W.,
do hereby declare the nature of this invention to be as follows:-
A patent safety gas or water cock which it is impossible to turn on accidentally
& which is calculated to reduce waste of gas & water, also to reduce the risk of
gas explosions to a minimum. The tap is made in the form of any common
tap now in use but is fitted with a small spring & turns on an inclined plane
ending in a small notch into which a small tooth attatched to the tap is pulled
by aforementioned spring when the tap is turned off the result being that the
tap automatically locks itself. This tooth firmly fixes the tap so that it cannot
be turned on until the tooth is released by a slight pull of the tap.

ALBERT WILFRED COTTON, Theatrical Manager, HOWARD TALBOT, Professor of
Music, both of 3, Welbeck Mansions, Welbeck Street, London, W., do hereby
declare the nature of this invention. and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement;
-
This cock consists of three parts viz.:-body, stop plug, and improved
mechanism for locking plug. The stop plug may be of any form and has a
square or other suitable hole drilled throughout its length, in which fits a square
or other suitable shank with tap for turning on and off. This shank is free to
move up and down without affecting stop plug but when turned it also turns
stop plug. Gases or liquids travel round plug as shewn at a-b. On the opposite
end of shank to tap there is a drilled and tapped hole for small split pin. This
split pin holds a spring of suitable pattern against end of plug. A cap fits over
all working parts to keep them free from dust, and the like. Under the tap
end of shank is a small pin which engages with small slot in body of tap to
automatically lock the tap when it is turned off. A slight pull on tap frees the
pin from slot and tap can be turned on. The automatic locking of the tap

Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is:-
(1)-Automatic locking of gas and liquid cocks in ordinary use which obviates
all possibility of any accidental turning on of said cocks.
(2) Permanent locking of gas and liquid cocks which prevents any
unauthorised use of gases or liquids for the tapping of which said cocks are used.
