PROVISIONAL SPECIFICATION.
An Electric Lighting Apparatus to be used in connection with Gas
Burners.
I, LEO ELIASSON, of 6 Square du Roule, Paris, in the Republic of France,
Merchant, do hereby declare the nature of this invention to be as follows :-
The present invention has for its object an electric lighter for gas burners
specially applicable for gas burners of the Auer and analogous types.
This lighter enables a gas burner to be instantaneously lighted and extinguished
at a distance as is the case with electric lamps.
Each gas burner is provided with its lighter and this lighter is comprised in a
circuit, such as an electric bell circuit.
Of course the same electric circuit may govern any number of lighters.
The apparatus is composed of a tube tapped at the bottom. to receive the gas
tubing and threaded at its upper part for the purpose of having a burner screwed
on it.
The lower portion of this tube is internally narrowed and is pierced horizontally
with a conical opening to receive a plug.
A small channel in the conical opening communicates with an auxiliary burner
consisting of a vertical tube with numerous perforations.
The conical plug is pierced with a hole.
The stem of this plug. has a ratchet wheel fixed upon it and at its end is a thumb
piece for turning the plug by hand it necessary.
Fixed upon the tube is a frame which also carries the bobbin of an electro magnet,
the armature is hinged to another part of the frame.
This armature is kept raised by means of a spring and abuts against a stop ring
op the tube.
A pawl or driver is hinged to the armature and engages with the
teeth of the above mentioned ratchet wheel.
Near the auxiliary burner an igniter formed of a platinum wire is arranged it
becomes incandescent on the passage of the current.
When it is wished to light the gas, a button placed anywhere in the circuit is
pressed. The current passes, the platinum wire becomes incandescent and the
armature is attracted to the bobbin.
The ratchet on the armature causes the plug to turn through an arc of 45°.
Gas thereupon passes into the auxiliary burner by the hole in the plug and the
channel in the conical opening into which the plug is fitted. The gas ignites on
contact with the incandescent wire. By pressing the button a second time the
armature which has been again litted by its spring again descends and causes the
plug to complete the quarter turn.
The gas then passes to the burner and ignites by contact with the flame of
auxiliary burner into which the gas then ceases to enter.
If it be wished to decrease the intensity of the flame, the button is again pressed,
the armature is again attracted, the plug is again moved and the gas is turned
down..
Another pressure on the button causes the gas to be turned off.
The apparatus is then in position to recommence its cycle of operations.
The main burner may be lighted directly by means of the incandescent wire but
I prefer the arrangement described

page_text: I may also light several burners by means of a single auxiliary burner suitably
placed.
In certain cases it is advantageous to substitute for the electro magnet two
solenoids which alternately actuate the plug of the gas cock
The armature when attracted by one of the solenoids opens the passage for the
gas and lights the burner; and when the armature is moved by the other solenoid
it closes the passage to the gas and puts out the light.

An Electric Lighting Apparatus to be used in connection with Gas
Burners.
I, LEO ELIASSON, of 6 Square du Roule, Paris, in the Republic of France,
Merchant, 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 :-
'
The present invention has for its object an electric lighter for gas burners
specially applicable for gas burners of the Auer and analogous types.
This lighter enables a gas burner to be instantaneously lighted and extinguished
at a distance as is the case with electric lamps.
Each gas burner is provided with its lighter and this lighter is comprised in a
circuit, such as an electric bell circuit.
Of course the same electric circuit may govern any number of lighters.
My apparatus is represented by the drawings annexed.
Figure 1 is a front elevation, and shows the lighter full size. Figure 2 is a side
view.
Figure 3 is a section on the line a, a, in Figure 1.
Figure 4 shows the key and plug of the cock.
Figure 5 shows four different positions of the key.
The apparatus is composed of a tube a tapped at the bottom to receive the gas
tubing and threaded at its upper part for the purpose of having a burner screwed
on it.
The lower portion of this tube is internally narrowed at a¹ and is pierced
horizontally with a conical opening a² to receive a plug b.
A small channel as in the conical opening communicates with an auxiliary burner
consisting of a vertical tube c in which are numerous perforations.
The conical plug b is pierced with a hole b'.
The stem of this plug has a ratchet wheel
fixed upon it and at its end is a
thumb piece for turning the plug by hand if necessary.
Fixed upon the tube a is a frame d which also carries the bobbin e of an electro
magnet, the armature fis hinged to another part of the frame.
This armature is kept raised by means of a spring f' and abuts against a stop
ring'g on the tube. A pawl or driver is hinged to the armature and engages
with the teeth of the above mentioned ratchet wheel.
h' is a spring which holds the pawl or driver in engagement with the teeth of
the ratchet.
Near the auxiliary burner at i an iguiter formed of a platinum wire j is arranged,
it becomes incandescent on the passage of the current.
When it is wished to light the gas, a button placed anywhere in the circuit is
pressed. The current passes, the platinum wire ; becomes incandescent and the
amature is attracted to the bobbin.

page_text: The ratchet and the pawl or driver on the armature cause the plug to turn
through an arc of 45° from the position marked No. 1 in Figure 5 which is "tap
closed" to the position shown at Figure 2. The hole b¹ in the plug is sufficiently
large to overlap in this position both the gas inlet and the entrance to the channel a*.
Gas thereupon passes into the auxiliary burner c by the half open hole 6¹ in the
plug and the channel a³ in the conical opening into which the plug is fitted. The
gas ignites on contact with the incandescent wire j. By pressing the button a
second time the armature f which has been again lifted by its spring again
descends and causes the plug to complete the quarter turn which brings it to the
position No. 3.
The gas then passes to the burner and ignites by contact with the flame of
auxiliary burner into which the gas then ceases to enter.
If it be wished to decrease the intensity of the flame, the button is again
pressed, the armature is again attracted, the plug is again moved to the position
No. 4 and the gas is turned down.
Another pressure on the button causes the gas to be turned off and brings the
plug to the position No. 1.
The apparatus is then in position to recommence its cycle of operations.
A small spring not shown in the drawings may be provided to give greater precision
to the movements of the plug to the four positions indicated by Figure 5.
The main burner may be lighted directly by means of the incandescent wire but
I prefer the arrangement described.
I may also light several burners by means of a single auxiliary burner suitably
placed.
In certain cases it is advantageous to substitute for the electro magnet two
solenoids which alternately actuate the plug of the gas cock.
The armature when attracted by one of the solenoids opens the passage for the
gas and lights the burner, and when the armature is moved by the other solenoid it
closes the passage to the gas and puts out the light.
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. In an electric lighter substantially as described, a plug or key actuated by a
ratchet and pawl receiving movement from the armature of an electro-magnet to
open and close the gas supply.
2. In an electric lighter substantially as described an electric igniter operating
in conjunction with an auxiliary burner or perforated lighting tube which latter
may serve one or more burners.
3. An electric lighter substantially as described and illustrated by the annexed
drawings.
