COMPLETE SPECIFICATION:
Improvements in Electrical Igniting Devices for Distant Gas
Lamps or Burners.
I, WILHELM KLINGER, of 12, Ritterstrasse, of Berlin, in the Kingdom of Prussia,
German Empire, manager, 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 improvements in electrical devices for simultaneously
igniting the gas of gas-burners located at a distance from such device, my improve-
ments having for their object or possessing the advantages of an increased safety
and certainty in operation, secondly the possibility of simultaneously igniting the
gas-flames of an optional number of burners or lamps, and also to furnish a simple
and economical installation mechanism for the attainment of this object.
In order to make my invention clear, refer to the accompanying drawing, in
which similar letters denote similar parts throughout the several views, and in
which:
Figure 1 illustrates the electromagnet “U”
Figures 2-5 various details, and
Figure 6 a general view of a complete installation.
The principle and main features of my invention consist in the employment of one
flow and return circuit only, by means of which it is possible from one point, to open
the valve or cock belonging to each gas burner, and to ignite the gas issuing
therefrom.
In carrying my invention into effect, my chief aim is to localise the difficulty of
insulating induced currents, for the reason that, when employing an inductorium or
induction coil, the induction currents of which are sent into the circuit, only a small
number of the gas flames can be simultaneously ignited; moreover, a greater length
of spark must be obtained from the induction-coil in proportion to the number of
burners to be simultaneously lighted. Such sparks, however, are only obtained from
currents of high intensity, whereby again, even at considerable expense, it is scarcely
possible to insulate the gas service and lamps from intense currents. I therefore
introduce into a circuit, in which the primary coils p, of an optional number of
induction coils J are situated, an electromagnet U (Figures 1 & 6) the armature A
of said electromagnet U during the passage of the current, through the coils R of
the said electromagnet, actuates the two contact springs ff in such manner, that
an electric current can pass from one spring to the other, which effects a shunt, with
no resistance to the coils R and cause these to lose their current. The armature A
however, after the disappearance of the magnetism in the electromagnet, and in
consequence of the inertia of the same, maintains its movement for a short time,
and by separating the springs f and f¹ opens thus the entire circuit, from which, as
above mentioned, the resistance of the coils R of the electromagnet had been switched
out.
The armature A now returns to its former position and the above mentioned
operations are repeated until the circuit is held closed by means of suitable
contact mechanism.
:

page_text: Each lamp is provided with an induction coil J, the core of which has an opening
or channel to allow of the gas passing to the burner, the said gas channel being in
the direction of the longitudinal axis of the coil.
The secondary winding, s, of the induction coil is connected on the one side with
the metal mantle, and on the other with the wire core of the igniting tube Z, and
insulated from the former by means of glass pearls in any suitable manner, though
not represented in the drawing.
The employment of glass pearls is for the purpose of preventing the springing
over of sparks at incorrect points between the mantle and the said wire core and for
the purpose of rendering the insulation less sensitive to the flame, or being injured
by the same.
Immediately above the electromagnet core is located an armature a movably
arranged between the poles of a permanent electromagnet M, said armature being
polarised by magnetic influence in accordance with the direction of the primary
current flowing round the electromagnet. In accordance therefore with the direc
tion of the current flowing round the electromagnet U the armature a is either
attracted or repelled from one or the other pole of the circular magnet M.
The said armature acts directly upon the valve V, in such manner that the
closing mechanism of the valve is either depressed or lifted, for which purpose the
said closing mechanism of the valve is manufactured of magnetic material, the same
operation can however be mechanically effected by constructing the armature of a
special shape.
The changing of the direction of the current is effected by means of switch
boards.
My improved installation device is operated in the following manner:
By pressure upon the one knob of the double-contact mechanism, or push-button
board D, the electric current of a battery B is sent into the circuit, the current
interrupter U comes into operation, and in the secondary windings s of the various
induction coils J, secondary currents are induced, which produce or send out at the
point F of the igniting tube Z, sparks, the intensity of which can be increased by
the shunting in of a condenser between the points c and c¹ of the apparatus U. At the
same time the valve V is opened, said valve being immediately under the gas nozzle
so that the gas issuing from the same, comes at once direct in contact with, or close
to the igniting flame. If now the second knob of the contact board D be pressed
down, the armature, a, would close the valve V and thus extinguish the flame.
Further the igniting tubes can be horizontally or vertically adjusted by means of
the screws S S¹ S2 thus the spark within the igniting zone can be easily regulated
and caused to long maintain its proper position.
Figure 6 shows various shunting combinations, firstly where in connection with
the double contact board or contact mechanism D¹, only the lamp L¹ is ignited or
extinguished, whereas, secondly, the contact mechanism D³ serves 5 lamps, which
number can, as before mentioned, be optionally increased.
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. A device for the ignition of gas flames of gas burners, gas lamps and the like,
located at a distance from such device, in which, an induction coil J is arranged
within the body of said burner, for the purpose of rendering the otherwise difficult
insulation of the gas tubing unnecessary and of increasing the number of gas flames,
substantially as described.
2. In a device for the ignition of gas flames of gas burners, gas lamps and the
like located at a distance from said device, an electromagnet (p), supplying the
igniting spark, in combination with a gas valve upon each lamp or burner, said
device adapted to be actuated by simply one flow and return current,
substantially as described.
3. A gas valve adapted to be actuated by electricity from a distant point, in

page_text: which the opening or closing mechanism of such valve is adapted to be operated by
an armature (a) of a permanent Electro-magnet (M), said armature being either
polarized by the electromagnet (p), or constructed as an independent electromagnet,
substantially as described.
4. A gas igniting tube (Z) for the installation device of the kind described in the
foregoing specification, said tube being capable of horizontal and vertical adjust-
ment, for the purpose of accurately and easily regulating the igniting sparks in the
proper igniting zone, the metal mantle of such device being adapted to serve as a
conductor, and is insulated from the wire core of the said igniting tube by means
of glass pearls, for the purpose of obviating the springing over of sparks between
the mantle and wire core, excepting at the point where the gas is ignited, and also
to prevent said insulation being injured by the heat of the gas flame, substantially
as described.
