A Means for Automatically Regulating the Supply of Gas to the
Burners of Gas Stoves and other Gas Heating Apparatus.
CALEB JONATHAN SPARROW 32 Hampstead Road London N.W. Hatter JOHN:
OSGERBY 69 Prince of Wales Road, N.W. Gas Engineer do hereby declare the nature
of this invention to be as follows:-
-
An improvement in burners for automatically shutting off and restoring the supply
of gas to all kinds of Gas stoves, atmospheric or otherwise, and all kinds of gas
heating apparatus. The principle involved is an arrangement of a spring or springs
under or above one or any number of gas burners which are connected with valves,
which shut off the supply of gas, when the spring is released by the removal of the
article being heated from the burner or stove, and when replaced restores the supply
of Gas to the burner which ignites by the light from the adjoining burner, or by a
pilot light fixed inside the stove.

CALEB JONATHAN SPARROW 32 Hampstead Road London N.W. Hatter JOHN
OSGERBY 69 Prince of Wales Road N.W. Gas Engineer 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:—
An improvement in burners for automatically shutting off and restoring the supply
of gas to all kinds of gas stoves atmospheric or otherwise, and all kinds of gas heating
apparatus. The principle involved is an arrangement of a spring or springs under or
above one or any number of gas burners which are connected with valves, which
shut off the supply of gas, when the spring is released by the removal of the article
being heated from the burner or stove and when replaced restores the supply of gas
to the burner, which ignites by the light from the adjoining burner or burners or by
a pilot light fixed inside the stove at any part of the burner.
The valves herein before refered to may be placed in a vertical position instead of
revolving as shown in drawings.
An ordinary cock or valve is used to regulate pressure in the supply of gas before
or after entering our valve or cock.
If we want the burners to keep alight after the removal of the article being heated
we keep them down by a hook pin or stop.
The springs may be either spiral, or vertical, and used under the burner or as
shown in the drawing.
By refering to the drawing it will be seen that the gas enters at a a portion of
.which passes by the small hole. b. to the pilot light, p. the gas also passes the slot C
and smaller slots s to the nipple n where it mixes with the atmospheric air at the
opening m then passing into the tube I which can be made any shape burns at the
holes e.
Upon the tube we fix a platform, gallery, support, or use stops, for whatever
kind or shape of article to be inale hot, not shewn in the drawings.
It will be seen by placing any article upon the above mentioned platform it will by
its weight turn the cock with its tube 7, operating on the spring and put the
apparatus in the position shown in Fig. 1 parallel with the pilot light allowing the
gas to pass by the slots into the tube through the holes e and immediately igniting.
And on removal off the article will spring back and shut off the gas.

Fig. 3 shews it at A.
Having now particularly described the nature of our said invention and in what
manner the same is to be performed we declare that what we claim is
The arrangement of the slot or slots in combination with the springs & apparatus
as herein before described and shown in drawings and substantially in the manner sot
forth.
