COMPLETE SPECIFICATION.
Ignition- and Gas-generating-body for Explosive Engines Rendered
Incandescent by an Electric Current.
I, ANTON NIEMCZIK of 5 Wiesenstrasse, Leipzig-Eutritzsch, Germany,
Manufacturer, 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:-
The object of the present invention is a body rendered incandescent either
continuously or intermittently by an electric current, and which may be used in
petroleum engines for generating gas from petroleum, and for the subsequent
ignition of the mixture.
The great advantage of this kind of ignition- and gas-generating body is that it
renders an open flame entirely unnecessary and thus the motor may be used also in
places where combustible or explosive gases may be present.
On the accompanying drawing
Fig. 1 is a longitudinal section of the part in question of a petroleum engine.
Figs. 2 and 3 are longitudinal sections of petroleum engines in which the
incandescent body is arranged somewhat differently.
Fig. 1 shews one of the ordinary petroleum engines in which the petroleum is
injected through the tube b and the air let in through the valve v.
gauze z.
In the wall of the cylinder are the two poles of the current conductor i i, well
packed and insulated, connected inside of the cylinder with each other by wire
Both poles are in connection with a dynamo machine, driven by the
motor itself. In consequence, the thin wire gauze z, serving as resistance, becomes
heated and serves for ignition of the mixture of air and petroleum, just in the
same way as the ignition tubes till now in use, heated by an exterior flame, and
which also in petroleum engines perform both functions.
In Fig. 2 the incandescent body z is in the form of a peculiar conical wire spiral.
This form of the incandescent body z is also retained in Fig. 3; but here a cover k,
made of fire-proof non-conducting material, for instance porcelain, is placed around
the incandescent body for its preservation. The cover provided with holes o is
heated by the incandescent body the functions of which, generation of gas from
the petroleum and the subsequent ignition of the mixture, are then also taken
up by it.
The arrangement admits of an easy starting of the machine, if a secondary or
primary battery is in readiness for supplying the current.
With small dynamo
machines the necessary current for starting the incandescence can also be easily
produced directly.
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:
1. An incandescent body z, for generation of gas and subsequent ignition of the
mixture, in petroleum engines, kept continuously or intermittently incandescent by
an electric comment

page_text: 2. An incandescent body as claimed in Claim 1, which for the purpose of greater
durability is provided with a cover k. made of fire-proof non-conducting material,
as described.
