Improvements in Electrical Apparatus for Igniting Gas Burners from
a Distance.
I, CARL BOLLÉ, of 57, Barton Arcade, Manchester, in the County of Lancaster,
Consulting Engineer, do hereby declare the nature of this invention, which has
been communicated to me by Carl Fitzlaff, of Berlin, in the German Empire,
Erector, to be as follows:-
This invention relates to electrical apparatus for igniting gas burners from a
distance and consists in the hereinafter described improvements in such appa-
ratus, the objects of the invention being to assure increased certainty of ignition
on the one hand and certainty of extinction on the other hand.
For the purposes of this invention a cock is arranged in the gas supply pipe
as usual, the turning of which in one or the other direction opens or closes the
gas outlet to the burner. On the plug of the cock a crankpin is arranged the
pushing of which to one side or the other turns the plug into its opening or
closing position. This movement of the crank pin is effected by a slotted lever
or its equivalent engaging the pin, which lever is attached to the armatures
of two electro magnets placed one on each side of the cock, the armatures being
iulcrumed on a stud below the rock.
On one, say the right hand side, the induction bobbin for the electro-magnet
which effects the ignition, hereinafter called the ignition bobbin, is placed with
its axis in a vertical position, and on the left hand side the electro-magnet
effecting the extinction, hereinafter called the extinction bobbin. These are
connected with separate leads for the electric current in such a manner, that
in closing the circuit by means of an ignition button at any distance from the
burner a current is sent through the ignition bobbin, and by closing the circuit
by means of another contact, the extinction button, a current is sent through
the extinction bobbin, the bobbins being of the same size.
The armature of the extinction bobbin and the core of the bobbin are so
arranged that they are nearer to each other than the core and armature of the
ignition bobbin so that a current which can only excite the extinction bobbin
sufficiently to lift its armature and move the gas cock into its closed position.
does not suffice to lift the ignition armature and open the cock. In addition io
this the ignition armature is further loaded by an iguiting rod under spring
pressure, which it must lift in order to produce the sparking for lighting the gas.
The ignition magnet thus has to perform much more work, so that if the current
sent through the leads from a distance is sufficiently strong to open the cock
and light the gas. it is certain to be strong enough also to effect the closing.
To light the gas burner. for instance for an incandescent gas lamp, a pilot
jet is arranged at its side, which is first lit by electric sparks and then lights the
main burner. For this purpose a bypass is arranged above the cock leading to a
vertical tube, which is in conductive connection with the ignition bobbin, and
armed at its upper end with a strip of platinum. Inside the tube and suitably
insulated from it, an igniting contact rod is arranged, which at its upper end
is armed with a platinum point ordinarily resting upon the strip of platinum!

and at its lower end is at such distance from the ignition armature, that the
latter has to lift the igniting rod before opening the cock. When a current sent
through the ignition bobbin can do this, the platinum strip and point are thus
separated and the sparks between them light the pilot jet, which in its turn lights
the main burner. If the current is insufficient to do this the cock remains closed, 5
while if it is sufficient to do so, and if the force required for lifting
the igniting rod is greater that that required for turning the cock, the
current will have also sufficient strength to close the cock when the extinction
bobbin is excited by pushing down the extinction button. A spring is arranged
for pressing the igniting rod downwards, by means of which the force required 1
for lifting it can be adjusted so as to meet the above requirements.
Improvements in Electrical Apparatus for Igniting Gas Burners from
a Distance.
I, CARL BOLLÉ, of 57, Barton Arcade, Manchester, in the County of Lancaster,
Consulting Engineer, do hereby declare the nature of this invention, which has
been communicated to me by Carl Fitzlaff, of Berlin, in the German Empire,
Erector, 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 electrical apparatus for igniting gas burners from a
distance and consists in the hereinafter described improvements in such appa-
ratus, the objects of the invention being to assure increased certainty of ignition
on the one hand and certainty of extinction on the other hand.
On the drawing appended hereunto the improvements are shewn applied to an
incandescent gas burner, Figures 1 and 2 showing a front and side elevation,
Figure 3 a cross section along line X X and Figure 4 a cross-section along
line of Figure 1.
For the purposes of this invention a cock B, is arranged in the gas supply
pipe A, as usual, the turning of which in one or the other direction opens or closes
the gas outlet to the burner. On the plug of the cock a crankpin C is arranged
the pushing of which to one side or the other turns the plug into its opening
or closing position. This movement of the crank pin C is effected by the
armatures,, of two electro magnets placed one on each side of the cock, the
armatures being fulerumed on studs below the cock.
On one, say the right hand side, the induction bobbin % of the electro magnet
which effects the ignition, hereinafter called the ignition bobbin, is placed with
its axis in a vertical position, and on the left hand side the bobbin L of the
electro magnet effecting the extinction, hereinafter called the extinction bobbin.
These are connected with separate leads for the electric current in such a manner
that in closing the circuit by means of an ignition button at any distance from
the burner a current is sent through the ignition bobbin Z, and by closing the
circuit by means of another contact the extinction button, a current is sent through
the extinction bobbin L, the bobbins being of the same size or power.
When the armature is attracted by the core of the ignition bobbin %, an
arm fixed on it moves the crank pin C to the left and opens the gas cock,
a slot being provided in the plate holding the cock B in its place for the
pin C to work through. When the circuit is broken and the armature Z released,
the arm & returns to its original position, leaving the pin C at the left end

page_text: of the slot c. When the bobbin L is excited to extinguish the light,
the armature is attracted and an arm e fixed on it moves the pin C to the right
and closes the cock, the pin remaining in the position shown on the drawing
when the armature is released by reteasing the extinction button.
The armature of the extinction bobbin Land the core of the bobbin are so
arranged that they are nearer to each other than the core and armature z of the
ignition bobbin %, so that a current which can only excite the extinction
bobbin L sufficiently to lift its armature, and move the gas cock into its closed
position, does not suffice to lift the ignition armature and open the cock. In
addition to this the ignition armature is further loaded by an igniting rod f
under spring pressure, which it must lift in order to produce the sparking for
lighting the gas. The ignition magnet thus has to perform much more work, so
that if the current sent through the leads from a distance is sufficiently strong
to open the cock and light the gas, it is certain to be strong enough also to effect
the closing.
i
To light the gas burner, for instance of an incandescent gas lamp, a pilot jet
is arranged at its side, which is first lit by electric sparks and then lights the
main burner. For this purpose a bypass is arranged above the cock, in the
part A of the pipe A leading through a tube a to a vertical tube F which extends
above the burner tube provided with air inlets in the known manner.
opening the cock B, the gas will flow more rapidly through the bypass to the top
of the tube F than the mixture of air and gas will pass through the burner tube
of the burner.
On
The ignition tube F is in conductive connection with the bobbin L and armed
at its top end with a small strip of platinum p, while inside the tube and
suitably insulated from it a movable contact rod f. is arranged carrying at its
upper end a platinum point p', which ordinarily rests upon the strip, in which
position the lower end of the rod f is at such a distance from the armature z of
the ignition bobbin %, that the armature has to lift the contact rod f before
opening the cock B. This rod is in conductive connection with the ignition
bobbin Z, as indicated by the stroke and dot lines on the drawings. When the
current is sent through the ignition bobbin Z, it has not only to lift the armature=
and to turn the cock thereby but has also to lift the contact rod f, loaded by a
spring h, and if able to do so a spark will pass from the point to the strip p
and ignite the gas passing out of the tube I, the flame then igniting the gas
issuing from the burner tube r. If the current is not sufficiently strong to do so,
the cock remains closed, while if it can do so, especially when the power required
for lifting the contact rod is greater than that required for turning the cock, then
the battery will also possess sufficient strength of current to lift the armature
of the extinction bobbin L when the extinction button is pressed, and thus to
close the gas cock. The lift of the contact rod f is so small that during the whole
time the ignition button is pressed down and current sent through the ignition
bobbin, a continuous sparking takes place between the platinum points and pl.
When the gas cock is to be closed, the extinction button is pressed down and the
current sent through the extinction bobbin L. As the distance of the armature
from the core of the extinction bobbin L is for instance only half the distance of
the armature from the ignition bobbin Z, half the strength of current required
for opening the cock would suffice for closing the same, but as the ignition
armature has further also to lift the contact rod f, a still less strength will
suffice, so that when the gas has been ignited, even if the battery is nearly
exhausted, there will remain a sufficient remnant of electrical force to close the
open cock again.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is:-
1 In alcotrical annarains for iœniting ons lights from a distance the arrange,

page_text: ment of two separately excitable equal hobbins for the ignition and extinction
of the gas respectively, of which the ignition bobbin has to perform more work
than the extinction bobbin, in consequence of having to attract the armature to a
greater distance than that of the armature of the extinction bobbin and also to
lift a spring loaded contact and sparking rod, in order that a current capable of
effecting the opening of the gas cock will also effect the closing of the same with
certainty, substantially as hereinbefore described.
2. The arrangement or construction of electrical apparatus for igniting gas
from a distance substantially as herein before described and illustrated by the
drawings.
