An Improvement in Gas and other Taps or Cooks for Preventing
Leakage.
CHARLES KING 58 Ashmead Road St. John's, London S.E. Commercial
Manager for R. & H. Green Ld. Engineers and Ship Builders Blackwall,
London do hereby declare the nature of this invention to be as follows:-
The principal parts of this invention are a spring a peg or spigot a groove for
the peg to work in, and a hole into which the peg will fall. The groove is made
in the plug of the tap and a hole made in the groove. The peg is fixed upon the
spring and the end of the spring is fixed upon the body of the tap. The peg
remains by pressure of the spring in the groove and prevents the plug from falling
out when loose, and when the tap is turned off the peg falls into the hole and the
tap cannot be turned on again unless the spring is released. The spring is made
of steel or brass or other suitable material. The spring and peg may be made
separate so that they may be fitted to already existing taps, or the spring may be
made with the hole in it and the peg fixed upon the plug instead.
This invention is specially suited to gas taps but is also applicable to all taps of
other description. By additional holes in the plug or additional spigots or pegs
this tap or cock can be regulated as required when in use.

COMPLETE SPECIFICATION.
An Improvement in Gas and other Taps or Cocks for Preventing
Leakage.
I CHARLES KING of 58 Ashmead Road, St. John's, London, S.E. Commercial
Manager for R. & H. Green Ld. Engineers and Ship Builders, Blackwall,
London, 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 improvement in gas and other taps or cocks for
preventing leakage.
The principal parts of this invention are:-A spring, a peg or spigot, a groove
for the peg to work in, and a hole into which the peg will fall. The groove is made
in the plug of the tap and a hole made in the groove. The peg is fixed upon the
spring and the end of the spring is fixed upon the body of the tap. The peg
remains, by pressure of the spring, in the groove and prevents the plug from
falling out when loose and when the tap is turned off the peg falls into the hole
aud the tap cannot be turned on again uuless the spring is released. The spring is
made of steel or brass or other suitable material. The spring and peg may be

page_text: made separate so that they may be fitted to already existing taps, or the spring
may be made with the hole in it and the peg fixed upon the plug instead.
This invention is specially suited to gas taps but is also applicable to all taps of
other description.
By additional holes in the plug or additional spigots or pegs this tap or cock
can be set or regulated as required when in use.
This invention will be clearly understood by reference to the annexed drawings.
Figure 1 side view of tap A with the plug B turned off.
Figure 2 end partly in section with plug B turned a quarter round or "on" the
plug B being locked by my improved appliance C which slips into a hole D at
either end or other parts of a groove E formed within the rim F of the tap body A
by the spring G.
Figure 3, indicates how by finger pressure the fastening device C can be released
to enable the plug B to be turned.
Figures 4 and 5 show an outside catch fastener C bearing upon a rin flange H
the body A having holes for the point to enter for locking the plug as in the first
described method."
Figures 6 and 7 show a drawback bolt kind of fastener C arranged within a
thimble I screwed to the body A of the tap the spring G of the bolt C when the
handle is released forcing the bolt home into a hole in the plug to lock it, either on
or off, the action of the spring causing a click to be heard when the bolt reaches a
hole provided at the end or other part of the groove or of the race on or in which
the fastener may travel.
The fastening device is s arranged in relation to a groove or rim that the plug
cannot accidently be disconnected or released from the tap.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed declare that what I
claim is :-
An improved gas cock with locking device for automatically locking the plug
when turned open or off or otherwise if so arranged and which device riding in a
groove or on a flange and provided with holes for preventing the cock plug from
falling out or from being accidentally turned on or turned too far when shutting
off the gas, as set forth and as represented by the annexed drawings.
