Improvements in Electric Apparatus for Lighting and Extinguishing
Gus Jets.
I, GOTTFRIED FERDINAND KRIEGER, of No. 71 Annenstrasse, Kiel, in the German
Empire, Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an electric gas-lighter for gas burners, especially those of
the incandescent type, and belongs to that class of electric gas-lighting or gas-igniting
devices which enable the igniting and extinguishing of the said gas burner or gas
burners to be effected from a distant station. The object of my invention is to procure
a simple, cheap and reliable igniting and extinguishing device; and with this end in
view my invention consists in certain novel features of construction and combinations
of parts as will be hereinafter described.
To the gas supply pipe carrying in the usual manner the ordinary burner tube of
an incandescent lamp, is attached by any suitable means, e.g., by a circular plate or
the like, an electro magnet having its coils connected with suitable circuit wires
leading from a central station to the said incandescent lamp. Above the said electro
magnet is arranged a suitable spring actuated armature lever. This armature lever is
pivotted to the gas supply pipe and has on its free end a moveably fixed upright arm
which engages a slotted disc on the projecting extremity of the rotary gas-cock
mounted in the gas supply pipe. The diametrical slot of the said disc attached to the
gas-cock, has on either of its ends a suitable enlargement or recess, the purpose of
which will be described further on. Suitable stop devices may be provided in order
to limit the rotary motion of the gas-cock according to its opened or closed positions,
respectively.
A small auxiliary burner tube which receives gas from the gas-supply pipe at a
place below the gas-cock, is kept constantly burning to ignite the main burner as soon
as the gas-cock has been opened.
The electro magnet and the other appliances for operating the gas-cock may be
enclosed in a suitable removable casing.
When the electric circuit is closed at the said distant station, the armature lever will
be attracted by the energized electro magnet. By this movement of the armature
lever, its arm engaging one of the said recesses of the slotted disc, is moved upward
and thereby rotates the gas-cock to a certain extent, limited by one of the above
mentioned stop devices, in order to open the gas cock for supplying gas to the burner
which will be ignited by the pilot flame of the auxiliary burner.
When the circuit is broken, the armature lever is moved back by its spring. To
prevent back motion of the gas cock when its operating arın is retracted by the
returning armature lever, the said operating arm is adapted to slide along in the slot
of the disc and to move from one of its recesses into the other. In this position, the
operating arm is adapted to rotate the gas cock in the opposite direction, and to cut'
off the gas supply to the burner as soon as, by closure of the circuit, the armature
lever is again attracted by the electro magnet.
After the circuit has been opened again, the operating arm of the gas cock, slides
again along in the slot of the said disc fixed to the gas cock, and moves into the recess
at the other end of the slot; in which position the operating arm is adapted to open
the gas cock in the manner above described.

page_text: From the above it will be clearly understood that the igniting as well as the
extinguishing of the burner may be effected from a distant station by simply closing,
each time, a circuit in which the said electro magnet operating the opening and closing
appliances of the gas supply is enclosed.
In some cases it may be desirable to dispense with the constantly burning pilot
flame and to ignite the burner by means of a small platinum wire. This may be
accomplished by arranging above an auxiliary-gas-jet tube, a platinum wire carried by
suitable supports which are enclosed in the circuit so that the current having passed
the electro magnet flows through the supports and platinum wire in order to heat the
latter so that it may ignite the gas escaping from the auxiliary tube. In this case the
auxiliary gas tube extends from the main gas supply pipe at a point above
the gas-cock.

Improvements in Electric Apparatus for Lighting and Extinguishing
Gas Jets.
I, GOTTFRIED FERDINAND KRIEGER, of No. 71 Annenstrasse, Kiel, in the German
Empire, Mechanical 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 an electric gas-lighting and extinguishing apparatns for
gas burners, especially those of the incandescent type, and belongs to that class of
electric gas-lighting or gas igniting devices which enables the igniting and
extinguishing of the said gas burner or gas burners to be effected from a distant
station. The object of my invention is to procure a simple, cheap and reliable
igniting and extinguishing device; and with this end in view my invention consists
in certain novel features of construction and combinations of parts as will be herein-
after described.
. I attain this object by the mechanism illustrated in the accompanying drawing, in
which
Figures 1 and 2, are two side elevations of a Bunsen burner of the incandescent
type provided with my improved lighting and extinguishing apparatus arranged in a
position at right angles to one another;
Figure 3, is a horizontal section on the line I-I, Figure 1;
Figures 4-6, are detailed views in enlarged scale, showing the connection of the
gas cock with the armature lever through a link, and
Figure 7 is a modification.
J
To the gas supply pipe a, carrying in the usual manner the ordinary burner tube b
of an incandescent lamp, is attached by any suitable means, e.g., a plate or disc c, an
electromagnet d having its coils connected through the conducting wires e with a
central station, where the electric circuit may be closed or broken. Above the electric
magnet d is arranged a suitable armature which is pivotally connected by means of
a bifurcated double-armed lever f¹ to the gas supply pipe a. A spring f' attached to
the armature tends to withdraw the latter from the pole of the electro-magnet. The
free ends of the bifurcated levers f¹ are connected on the other side of the gas supply
pipe with a traverse carrying a link 9 which is adapted to longitudinally slide upon
the traverse. This link engages with a stud g at its upper end a slotted disc hon
the projecting extremity of the gas cock i. The diametrical slot of the disc h has

page_text: on either of its ends a suitable enlargement or recess 2, the purpose of which will be
described hereinafter. A projecting stud of the cock i and suitable stops n of the
gas supply pipe are provided in order to limit the rotary motion of the gas-cock
according to its opened or closed position, respectively.
A small auxiliary burner tube o which receives gas from a branch o¹ of the gas
supply pipe at a place below the gas cock, is kept constantly burning to ignite the
main burner as soon as the gas cock has been opened. The quantity of gas
conducted to the auxiliary burner tube may be controlled by means of a small.
Screw o
The electro magnet as well as the other appliances for operating the gas-cock may
be enclosed in a suitable casing, which is shifted over from above and carried by a
plate c¹ provided for this purpose. A suitable guard may be arranged in front of the
disc h of the gas-cock i.
l
The operation of the apparatus will then be as follows:-
When the electric circuit is closed at the distant central station, the armature
lever f,,,, will be attracted by the energized electro magnet d. By this
movement of the armature lever, the upper end of the link 9 9' engaging the lowest of
the recesses h³, Figure 4, of the slotted disc h h is moved upward and thereby rotates
the gas-cock i from the closed position, Figures 1-4, into the open position, Figure 5,
limited by the stop device in. The gas thus admitted to pass the gas-cock i for
supplying the burner 6 will be ignited by the pilot flame of the auxiliary burner
tube o.
When the circuit is broken after the ignition of the flame the armature lever is
moved back into its position of rest by its spring f³. To prevent back motion of the
open gas-cock i when its operating arm or link g is retracted by the returning
armature lever, the link g is adapted to slide along in the slot h' of the disc h with its
stud g' from the upper extreme position, Figure 5, to the lowest, Figure 6. In this
position the link g is adapted to rotate the gas cock in the opposite direction and to
cut off the gas supply to the burner as soon as, by closure of the circuit, the armature
lever is again attracted by the electro-magnet d. The rotary movement of the gas-cock
is limited by a second stop n as above mentioned.
After the circuit has been opened again, the operating link y of the gas cock slides
again with its stud g¹ in the slot ' of the disc h and moves downward to the recess h
at the other end of the slot; the parts are then returned from the open position,
Figure 6, into the closed position, Figure 4.
From the above it will be clearly understood that the igniting as well as the
extinguishing of the burner may be effected from a distant station by simply closing,
each time, a circuit in which the electro-magnet d is enclosed.
When it is desired to dispense with the constantly burning bye flame, an
arrangement, as illustrated in Figure 7, may be used to ignite the said flame by
means of a small platinum wire stretched above an auxiliary gas-jet tube 9. The
platinum wire is carried by suitable supports s which are enclosed in the circuit so
that the current having passed the coils of the electro-magnet flows through the
supports and platinum wire r in order to heat the latter so that it may ignite the gas
escaping from the tube q. In this case the auxiliary gas tube extends from a
branch g of the main gas supply pipe a, at a point above the gas-cock i. A set-
screw q is designed for controlling the quantity of gas required for feeding the pilot
flame.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with the main burner, the igniter burner, gas passages leading
thereto respectively, and a normally closed valve in the main burner gas passages, of
an electro-magnet in a suitable electric circuit, an armature held normally retracted
from its magnet, an armature lever, and a link connected thero with provided with a

page_text: stud working in a diagonal groove in the end of the valve stem, for the purpose set
*forth.
2. The combination with the main burner, the igniter burner, gas passages leading
thereto respectively, and a normally closed valve in the main burner gas passages, of
an electro-magnet in a suitable electric circuit, an armature held normally retracted
from its magnet, an armature lever and a link connected therewith and provided with
a stud working in a diagonal groove in the end of the valve stem, said groove having
at each end a lateral recess, for the purpose set forth.
3. The combination with the main burner, the igniter burner, gas passages leading
thereto respectively, and a normally closed valve in the main burner gas passages, of
an electro-magnet in a suitable electric circuit, an armature held normally retracted
from its magnet, an armature lever, a link connected therewith and provided with a
stud working in a diagonal groove in the end of the valve stem, said groove having at
each end a lateral recess, stops on the valve stem, and fixed stops co-operating therewith
to limit the rotation of said stem in one or the other direction, for the purpose set
forth.
