Complete Specification Left, 10th Apr., 1900-Accepted, 10th Aug., 1900
PROVISIONAL SPECIFICATION.
Improvements in the Ignition Arrangements of Internal Combustion
Motors.
I, WILLIAM EDMUND SIMPSON, of 28, Victoria Street, Westminster, in the
County of London, Engineer, do hereby declare the nature of this invention
to be as follows:-
According to this invention, in one arrangement, an electrical igniter is formed
of a barrel or pipe in communication with the cylinder and having two insulated
plugs each carrying a sparking point, the plugs being preferably arranged
diametrically opposite to each other so that the sparks pass from one to the
other across the barrel. The outer end of the pipe or barrel is closed by a plug
similar to a cock-plug or otherwise moveable so as to allow of immediate access
to and inspection of the sparking points from the outside. An ordinary ignition
tube may be also fitted to the barrel or pipe, so that either tube or electric
ignition may be used, and said tube may be shut off from the cylinder when
required by another plug or cock, or by the one first described, which latter
may also be used for allowing compressed air or vapour to escape from the
cylinder and thus reducing the compression at starting, and also removing
deposits of carbon from the sparking points, while the motor is running.
Dated this 10th day of June 1899.

Applicant.
COMPLETE SPECIFICATION.
Improvements in the Ignition Arrangements of.Internal Combustion
Motors.
I, WILLIAM EDMUND SIMPSON, of 28, Victoria Street, Westminster, in the
County of London, Engineer, 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:-
This invention relates to ignition arrangements for internal combustion motors,
and has for its object to render the sparking points capable of being readily
inspected and cleaned.
The invention is illustrated in the accompanying drawing, which represents a
longitudinal section of an igniter.
According to the invention, in one arrangement an electrical igniter is formed
of a barrel or pipe a in communication with the cylinder, and having two insu-

page_text: lating plugs b, b, each carrying a sparking point, the plugs b, b being preferably
arranged diametrically opposite to each other so that the sparks pass from one
to the other across the barrel a. The outer end d of the pipe or barrel a is
closed by a plug e similar to a cock-plug or otherwise movable so as to allow
of immediate access to an inspection of the sparking points from the outside.
An ordinary ignition tube may also be fitted to the barrel or pipe a, so that
either tube or electric ignition may be used, and said tube may be shut off from
the cylinder when required by another plug or cock, or by the one e first described,
which latter may also be used for allowing compressed air or vapour to escape
from the cylinder and thus reducing the compression at starting, and also
removing deposits of carbon from the sparking points, while the motor is
running. For this latter purpose the passage f is preferably restricted near the
sparking points at f' so as to obtain greater velocity of the gases in their
passage between them.
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 a motor in which electric spark ignition is employed, a movable cock
or valve so arranged in relation to the sparking plug or plugs as to enable the
sparking points to be readily inspected.
2. In a motor in which electric spark ignition is employed, means for cleaning
the sparking points substantially as herembefore described.
