An Improved Electric Gas Igniting and Extinguisning Apparatus.
I, ALFRED CZARNIKOW, of 7, Kreuzberg Strasse, Berlin, in the Kingdom of
russia, Manufacturer, do bereby declare the nature of this invention and in what
anner the same is to be performed, to be particularly described and ascertained
and by the following statement :-
The present invention relates to an electric gas igniting apparatus with two
urrent circuits of which the one serves for igniting and the other for extin--
uishing the light.
Referring to the acccompanying drawings
Figure I shows a side view.
Figure II a front view.
Figure III a vertical section and
Figure IV the circuit diagram.
In the circuit A is interposed an electromagnet E and in the circuit a an
electromagnet e. The magnet E is secured to the carrier plate b closing the
switching apparatus upwards whilst the magnet e is fixed to the bearer d attached
to the lower plate c. The latter bears also the armature f of the electromagnet E.
articulated at the point d. The armature f is formed in horse-shoe shape for
the purpose of admitting the gas pipe g through it, and possesses on its under
side a projection h, which can engage behind the armature i of the electromagnet e
(which armature is articulated at ) whenever the armature is attracted by its
magnet. A set screw k is fixed in the armature i which acts through an elastic
cover drawn for the purpose of making gas-tight over the gas pipe upon the
valve m provided with a packing disc n and presses the same upon its seat so
that the gas is prevented from passing out of the channel o through the valve
chamber p into the channel 9. If in this position of the various parts the
circuit A be closed by means of the contact A', the armature f is attracted by
the electromagnet E so that the projection of the armature i is released and the
valve m opened under the influence of the spring r, the gas can then flow into the
burner. A rods is raised by means of the armature f which rod is usually held
down by means of the spring s'. The rods is interpolated like the second rod t in
the current circuit A (Figure IV) and rests by means of a bar u upon a bar v of
the rod t. When the rods is raised the pegs u and are separated from each
other so that a contact-break spark is caused by means of which the gas flowing
out of the tube w can be ignited. By means of this jet so ignited the gas flowing
out of the main burner is then ignited. If the ignition does not immediately result
at the first spark the armature falls in consequence of the interruption of the
current and the rods returns under the influence of the spring & to its normal
position. By the touching of the pieces u and the current circuit again closes.
In consequence of this the armature fis again attracted, the bar a raised and again

a contact-breaking spark caused between u and v.
until the gas is ignited by the sparks which rapidly follow each other whereon the
current is interrupted by opening the contact A'. The separate parts have then
assumed the position indicated in Figure III because the armature i during the

so that the electromagnet e attracts the armature i. This latter catches in con-
sequence of the sloping surfaces behind the projection h and is held by the same

valve m is pressed upon its seat by means of the set screw k and in this manner
the gas is shut off. As shewn in Figure III the switching mechanism proper is
protected by an envelope z, this latter possesses an opening through which the
set screw can be adjusted from the outside. The bars arranged upon the
carrying plate b to prevent the rod s from turning by means of a little peg a fixed
on the same, whilst the envelope y conducts the bar's in the longitudinal direction.
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. An electric gas igniter with two separate current circuits in which by closing
one current circuit the armature of an electromagnet f is attracted, which by
opening a contact (u v) causes sparking and simultaneously releases the armature i
(hitherto held fast by a projection ) of an electromagnet interpolated in the
second current circuit, in consequence of which the valve m held closed by the
armature i automatically opens under the pressure of a spring, whilst the extin-
guishing of the flame is effected upon the closing of the second current circuit by
the armature i pressing the valve m again upon its seat.
2. In the arrangement set forth in Claim 1 the arrangement of a set screw kin
the body of the armature i (which armature has the purpose of effecting the
closing of the valve); the set screw being accessible through an opening 2 of the
cover z and having the purpose of regulating or adjusting the admission of gas by
varying the size of the opening between the valve m and the channels v and q.
3. In the arrangement set forth in Claim 1 the arrangement of the valve in a
chamber closed to the outside by means of an elastic envelope whereby the
armature i acts through the envelope by means of a set screw upon the valve.
