COMPLETE SPECIFICATION.
An Ignition Apparatus for Gas, Petroleum, Oil, or Combustible-
vapour Motor Engines.
I, HERBERT SUMNER of 58 Wilford Grove, Nottingham, late of Kilmarnock N.B.
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 use and application of a travelling incandescent, coiled, or porous piece of
platinum, or other suitable metal, with or without flame, for the purpose of igniting
the charge, in gas, petroleum, oil, or combustible-vapour motor engines.
In a hollow cylindrical rod, I arrange and secure, a coiled, or porous piece of
platinum, on a central holder, opposite small circular openings on each side of the
hollow rod, so that a jet of gas, or Bunsen mixture, can be directed through the
said openings, on to the coil, or porous platinum, for the purpose of keeping it
incandescent.
This hollow rod carrying the incandescent platinum, is made to pass through a cell
or chamber in communication with the motor cylinder, by suitable stuffing boxes,
packed with asbestos, metallic, or other suitable packing, and at the proper moment
for the ignition of the charge in the motor cylinder, is actuated by a cam, eccentric,
or other suitable motion, wrought by the motor. It is also provided with a hood, or
shield which surrounds the small openings through the rod when the latter is at rest,
and having corresponding openings on each side, and through which the gas or
mixture is blown by a suitable nozzle, this shield is to prevent draughts of air from
cooling down the platinum, or diverting the gas jet.
For the purpose of making this my invention more clearly understood, I refer to
the drawings appended, and in which are shown, the different parts of the apparatus
in position, as described :-A being the hollow rod, B the holder carrying the
platinum C. D is the cell or chamber in communication with the motor cylinder.
E. F. are stuffing boxes. G the hood or shield. H the nozzle to direct the gas on to
the platinum through the openings J. J.
The ignition rod can be wrought from either end, or in any position, vertical,
angular, or horizontal, and can also be used as a starter by moving the rod by hand
to give
the first ignitions after the motor cylinder has been charged with combustible
mixture.

page_text: 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. The use and application of a hollow cylindrical rod, carrying a piece of incan-
descent platinum, passing through a chamber in communication with a motor cylinder
for igniting the charge therein.
2. The use of the above apparatus as a starter for motors.
