IMPROVEMENTS-IN-GAS STOVES
Year: 1885

page_text: I WILLIAM MOFFATT of Millfield Terrace Hexham in the county of Northum
berland, Ironfounder, do hereby declare the nature of my said invention for
"IMPROVEMENTS-IN-GAS STOVES"-to be as follows:-
This invention relates to certain improvements in or applicable to gas stoves
the object being to construct a gas stove or an appliance applicable to gas stoves by
which said stoves can be automatically lighted and extinguished and which may
be either a separate appliance or form part of the gas stove.
+
In carrying the invention into effect I proceed as follows:-In the centre, at
one side, or any part of the stove as may be convenient I place a small button or.
projection (or the stove or part of the stove itself may answer as the projection)
which button projects above the level of or forms part of the usual resting place
for cooking utensils, which said button is connected by a rod to an arm, which is
attached to a valve, or tap, and further by a connecting rod, or link, to a weight
or spring arranged below; there is also placed a tap on the gas tube and a pilot
light from the gas. tube extending into the space wherein the combustion is
destined to take place.
The action of the device is as follows:-
When the gas supply tap is turned on or opened, the gas flows along the tube
and is ignited at the pilot light. When a pan or kettle is placed on the stove, the
weight of the same presses the projection first described downwards which thereby
works the arm and opens the burner valve or tap thus automatically lighting the
main flame of the gas stove. Upon removing the pan or kettle the weight or
spring closes the valve or tap and automatically extinguishes the main flame
of the stove and leaves but the pilot light burning.
I wish it to be understood that my invention may be performed or carried into
practical effect by various mechanical means and I seek to claim an automatic
self lighting and extinguishing gas stove, or appliance for that purpose adaptable
to gas stoves already in use.

page_text: I WILLIAM MOFFATT of Millfield Terrace, Hexham in the county of Northum-
berland 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 :-
This invention relates to certain improvements in or applicable to gas stoves
the object being to construct a gas stove or an appliance applicable to gas stoves by
which such stoves can be automatically lighted and extinguished and which may
be either a separate appliance or form part of the gas stove.
In carrying the invention into effect I proceed as follows:-
In the centre, at one side, or any part of the stove as may be convenient I place
a button or projection (or any free acting part of the stove itself may answer as
the projection) which button projects above the level of or forms part of the usual
resting place for cooking utensils which said button is connected by a rod to an
arm which is attached to a valve or tap and further by a connecting rod or link
to a weight which may form part of the stove, or spring arranged below, there is
also placed a tap on the gas tube and a pilot light from the gas tube extending
into the space wherein the combustion is destined to take place.
In the drawings annexed hereto Fig. 1 is a cross section of a gas stove stand
fitted according to this invention and Fig. 2 is a plan view.
a is projecting free acting button or part of the stove, connected by a rod to an
arm or lever b connected to tap or valve c. The arm 6 is at its opposite end
connected by rod or link to a weight d or it may be a spring to act as counter-
poise, e is the gas tube with tap or valve f. g is a pilot light fitted on the gas
supply side of valve c. h is the discharge nozzle supplying the gas into the
perforated burner tube i.
The action of the device is as follows:-
When the gas supply tap f is turned on or opened the gas flows along the tube e
and is ignited at the pilot light g. When a pan or kettle is placed on the stove
the weight of the same depresses the projection a which thereby works the arm b
and opens the burner valve or tap c and the main flame of the gas stove will be
automatically lighted by pilot light g. Upon removing the pan or kettle the
weight or spring d will act to close the valve or tap and automatically extinguish
the main flame of the stove thus leaving but the pilot light burning.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it to be

page_text: understood that my invention may be performed or carried into practical effect
by various mechanical means operating substantially as set forth and I claim,
Firstly. An automatic self lighting and extinguishing gas stove or appliance for
that purpose adaptable to gas stoves already in use as and for the purpose herein
set forth.
Secondly. The combination of parts forming a gas stove constructed and opera-
ting as herein set forth and shown by the drawings.
