PROVISIONAL SPECIFICATION.
Improvements in Electrical Ignition Apparatus for Gas Burners.
I, RIDLEY JAMES URQUHART, of 57, Barton Arcade, Manchester, in the County of
Lancaster, Consulting Engineer and Patent Agent, do hereby declare the nature of
this invention, which has been communicated to me by the Actiengesellschaft for
Fabrikation von Broncewaaren und Zinkguss, vorm J. C. Spinn & Sohn, of
Wasserthorstrasse 9, Manufacturers, and Stanislaus Johann von Romocki, of
Krausenstrasse 76, Engineer, both of Berlin, in the German Empire, to be as
follows:-
This invention relates to apparatus for igniting gas flames by means of an electric
spark or a wire raised to incandescence and consists in an improved arrangement for
closing or opening the electric circuit by turning the cock of the burner and thus
producing the said spark or incandescence, and in improvements in the arrangement
or mounting of the induction bobbin used in connection with such electric igniting
apparatus.
In applying this invention to existing gas burners, a clip is fixed upon the plug of
the cock and has a segment formed on it. To the casing of the cock or the burner
tube a second clip is attached. with a layer of insulating material between the clip
and other parts. This clip has a tubular lug formed in it, in which a pin under
spring pressure can slide, the pin projecting into the path of the segment on the
plug.
Above the cock an ignition bobbin preferably placed into a case surrounding the
burner tube is arranged with the required sparking points or incandescent wire,
and electrical connections in the manner known or used for electrical gas igniting
apparatus, and the opening of the cock brings the pin and segment into contact or
out of contact as may be required to close or open the electric circuit and produce the
spark or incandescence.
In new cocks the contact segment is formed directly on the plug or fixed
thereto.
The ignition bobbin arranged in a casing below the burner is insulated from the
latter by being surrounded by paraffin or other insulating material ran into the
casing in a molten state. The casing itself is preferably made of two cups or saucers
fitting upon each other. If these are made of paper or other insulating material,
the filling with paraffin greatly increases the strength of the casing.

I, RIDLEY JAMES URQUHART, of 57, Barton Arcade, Manchester, in the County of
Lancaster, Consulting Engineer and Patent Agent, do hereby declare the nature
of this invention, which has been communicated to me by the Actiengesellschaft
fur Fabrikation von Bronce waaren und Zinkguss, vorm J. C. Spinn & Sohn, of
Wasserthorstrasse 9, Manufacturers, and Stanislaus Johann von Romocki, of
Krausenstrasse 76, Engineer, both of Berlin in the German Empire, to be as
follows:-
This invention relates to apparatus for igniting gas flames by means of an electric
spark or a wire raised to incandescence and consists in an improved arrangement
for closing and opening the electric circuit by turning the cock of the burner and
thus producing the said spark or incandescence. On the drawing appended here-
unto the improved arrangement for closing or opening the electric circuit is
represented in elevation.
In applying this invention to existing gas burners, a clip C is fixed upon the
plug B of the cock and has a segment c formed on it. To the casing of the cock
or the burner tube a second clip D is attached with a layer of insulating material
between the clip and other parts. This clip has a tubular lug formed in it, in
which a pin d under spring pressure can slide, the pin projecting into the path of
the segment c on the plug.
Above the cock an ignition bobbin preferably placed into a casing A surrounding
the burner tube is arranged with the required sparking points or incandescent wire,
and electrical connections in the manner known or used for electrical gas igniting
apparatus, and the opening of the cock by means of the handle b brings the
segment c into sliding contact with the pin d and past the same when the cock is
fully opened, as is required to close and re-open the electric circuit and produce the
sparks or incandescence.
In new cocks the contact segment c may be formed directly on the plug as part
thereof or fixed thereto in any convenient way.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that
what I claim is :-
The combination with a gas burner cock of a segment or equivalent surface
attached to the plug of the cock and arranged in such a manner that when the cock
is opened said surface makes a sliding contact and closes the circuit of an electrical
ignition apparatus arranged on the burner so as to ignite the gas, substantially as
herein before described and illustrated by the drawing.
