Appliance for Igniting and Extinguishing the Flames of Gas Burners.
I, OLIVER IMRAY, of Birkbeck Bank Chambers, Southampton Buildings, Chancery
Lane, in the County of London, Chartered Patent Agent. do hereby declare the
nature of this invention (as communicated to me from abroad by Industriewerke
Kaiserslautern Metall-und Porzellan Fabrikation, Gesellschaft mit beschränkter
Haftung, of Kaiserslautern, Bavaria, in the German Empire, Manufacturers)
to be as follows:-
This invention relates to an appliance for igniting and extinguishing gas
flames from a distance, which I will describe with reference to the accompanying
drawings in which Fig. 1 shews a vertical section and Fig. 2 a plan with the
top cover removed.
Upon the gas pipe is fixed by means of the nozzle ba hermetically closed
casing a, which is always filled with gas, that can flow through an opening c into
a small tube attached thereto leading to an igniting gas jet.
The ignition may however also be effected by an electric current or other
known means. In the casing a is contained an electro magnet d in front of
which is the armature f pivotted at one end. This armature is held away from
the electro magnet by a spring m when no current is passing. The closing
of the gas supply to the burner which is screwed to the nozzle i, is effected by a
toothed wheel g having small holes / arranged in a concentric circle, the number of
which holes is half that of the teeth of the wheel. The latter rotates upon a pin
screwed to a piece n arranged below the nozzle band having one or more small
channels formed through it.
The armature has pivotted to it a pawl k which is kept by a spring in gear
with the wheel g. At each closing of the electric circuit the armature f in being
attracted effects the partial rotation of the wheel g through a distance equal to
one tooth, in such manner that by the one such motion the holes h of the wheel
are brought over the holes of n, so that gas can then pass through the latter
to the burner so as to be ignited by the igniting flame while on the next motion
of the wheel the holes are closed by the body of the wheel y, whose holes are
then in an intermediate position, and consequently the gas supply is cut off and
the flame is extinguished. The construction shewn is advantageous on account
of its compact form, but it may be modified in such manner that the ratchet
wheel is not situated between the limbs of the electromagnet but below the
same, in which case the electromagnet would be situated with its axis parallel
to the axis of the gas conduit in the closed casing. This arrangement would
however make the casing comparatively high and therefore not so convenient for
introducing it betwen the gas pipe and the burner, as the construction shewn.
As the entire mechanism is contained in a hermetically closed casing, no
escape of unburnt gas can take place into the room should the mechanism get
out of order, as in the event of the burner flame not being lit all the gas entering
D... 01

page_text: the casing must issue through the small hole e and pipe leading to the continuously
burning lighting flame, where it is consequently burnt.
The appliance can be readily adapted to all existing gas burners, and is more
particularly adapted for use in shop windows, halls staircases, saloons and
offices, but can also be employed with advantage in dwelling rooms.

I, OLIVER IMRAY, of Birkbeck Bank Chambers, Southampton Buildings, Chancery
Lane, in the County of London, Chartered Patent Agent, do hereby declare the
nature of this invention (as communicated to me from abroad by Industriewerke
Kaiserslautern Metall-und Porzellan Fabrikation, Gesellschaft mit beschränkter

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 appliance for admitting and cutting off the gas
supply to gas burners from a distance, which I will describe with reference to the
drawings accompanying my Provisional Specification in which Fig. 1 shews a
vertical section and Fig. 2 a plan with the top_cover removed.
Upon the gas pipe is fixed by means of the nozzle a hermetically closed
casing a, which is always filled with gas, that can flow through an opening c into
a small tube attached thereto leading to an igniting gas jet.
The ignition may however also be effected by an electric current or other
known means. In the casing a is contained an electro magnet d in front of
which is the armature f pivoted at one end. This armature is held away from
the electro magnet by a spring m when no current is passing. The closing
of the gas supply to the burner which is screwed to the nozzle b, is effected by a
toothed wheel 9 having small holes h arranged in a circle concentric with the
wheel the number of which holes is half that of the teeth of the wheel The
latter rotates upon a pin serewed to a piece n arranged below the nozzle b and
having one or more small channels formed through it.
The armature f has pivoted to it a pawl k which is kept by a spring o in gear
with the wheel g. At each closing of the electric circuit the armature f in being
attracted effects the partial rotation of the wheel g through a distance equal to
one tooth, in such manner that by the one such motion the holes h of the wheel
are brought over the holes 7 of n, so that gas can then pass through the latter
to the burner so as to be ignited by the igniting flame while on the next motion
of the wheel the holes are closed by the body of the wheel g, whose holes are
then in an intermediate position, and consequently the gas supply is cut off and
the flame is extinguished. The construction shewn is advantageous on account
of its compact form, but it may be modified in such manner that the ratchet
wheel is not situated between the limbs of the electromagnet but below the
same, in which case the electromagnet would be situated with its axis parallel
to the axis of the gas conduit in the closed casing. This arrangement would
however make the casing comparatively high and therefore not so convenient for
introducing it between the gas pipe and the burner, as the construction shewn.
As the entire mechanism is contained in a hermetically closed casing, no
escape of unburnt gas can take place into the room should the mechanism get

the casing must issue through the small hole c and pipe leading to the continuously
burning lighting flame, where it is consequently burnt.
The appliance can be readily adapted to all existing gas burners, and is more
particularly adapted for use in shop windows, halls, staircases, saloons and
offices, but can also be employed with advantage in dwelling rooms.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. An appliance for admitting and cutting off the gas supply to gas burners
consisting of a closed casing into which the gas supply passes on its way to the
burner and which contains an electromagnet whose armature at each closure of
an electric circuit is made to effect the step by step rotation of a disc having a
number of holes in its periphery so anranged in connection with an outlet leading
to the burner that in one position of the disc a hole therein uncovers the said outlet
while on the next following closing of the circuit the disc is turned into a position
in which it closes the said outlet, substantially as described.
2. An appliance for admitting and cutting off the gas supply to gas burners
combined and operating as herein described with reference to the accompanying
drawings.
