Electrical Ignition Apparatus.
Year: 1899

We, FRANZ KÜPPER, Crefelder Strasse 13, and ANSBERT EMIL VORREITER,
Wilhelm Strasse 77-1, both of Aachen, Germany, do hereby declare the nature
of this invention to be as follows:-
This invention relates to an apparatus for igniting explosives or combustible
materials by means of an electric spark. The apparatus is designed to be
directly attached to the chamber or vessel containing the material to be ignited.
Thus when used for an explosion motor it is screwed into the wall or cover of
the cylinder.
This apparatus is an improvement on the forms of igniter hitherto used by
reason of its simplicity of construction and consequent certainty of action; for
the three principal parts of the inductor igniters hitherto in use (namely, coils
igniting leads and the actual igniter) are reduced to a single apparatus igniting
leads being eliminated.
The apparatus is supplied at the right moment with an electric current from
a suitable external source by a contact maker or the current source may be
contained in the apparatus itself if the casing is made of sufficient dimensions.
The drawing shews a section of one form of the apparatus in
which a is a primary coil of stout wire and a secondary coil of
fine wire, both being wound on a bobbins which is surrounded by the
condenser c.
The bobbins has an iron core d and is contained in an iron case e
which is split at several places in its periphery in order to avoid Foucault
currents.
The binding screw & passes through the wall of the casing and is insu-
lated therefrom. To it is attached one end of the primary coil a the other end
being fastened to the casing e. One end of the secondary coil b is also attached
to the casing, while the other end is connected directly or through a spring f

Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. An electrical ignition apparatus in which the inductor generating the high
tension electricity and the spark-gap are united without leads, the inductor being
contained in a casing attached to the chamber in which the ignition is to be
effected, substantially as described.
2. An electrical ignition apparatus constructed and operating as herein
described.
