PROVISIONAL SPECIFICATION.
An Improved Petroleum Motor.
I, THOMAS RICHARD SHILLITO of 89 Chancery Lane in the County of
Middlesex, Engineer and Patent Agent do hereby declare the nature of this
invention, a communication to me from abroad by Otto Ludwig Phillipp Swiderski
and Emil Capitaine, of Leipzig-Plagwitz in the German Empire Engineers, to be
as follows:
This invention relates to petroleum motors of a kind in which the vaporiser is in
constant open communication with the cylinder space and in which the air for
combustion does not pass through the vaporiser.
The invention consists, firstly, in an arrangement by which both the petroleum
and air is passed through a single inlet valve, the petroleum taking its way through
a vaporiser heated to a comparatively moderate temperature, the air on the other
hand passing direct into the combustion chamber or cylinder; and secondly, in an
arrangement by which any suitable quantity of air may be passed with the
petroleum through the vaporiser for the purpose of more conveniently driving the
motor as well as for preventing premature ignition of the petroleum in or at
the vaporiser.
The vaporiser is in the form of a bent open tube one end of which projects into
the combustion chamber and delivers the petroleum vapour thereinto in the same
direction as the entering air, the petroleum being conducted by a separate tube to
the inlet valve through which it passes direct into and through the vaporiser at the
time the inlet valve is opened by the suction of the piston. The vapour generated
in the vaporiser takes its way together with the air for combustion downwards to
the cylinder.
The admission of petroleum or of this with a governed quantity of air pust the
inlet valve is brought about by lessening the dimensions of the air passage between
the inlet and outlet of the vaporiser.
The ignition of the combustible gaseous mixture is not effected by any particular
igniting arrangement or by contact with hot surfaces but rather by compression in
the manner of the motors known as the "Capitaine" petroleum motors.

1, THOMAS RICHARD SHILLITO of 89 Chancery Lane in the County of
Middlesex, Engineer and Patent Agent, do hereby declare the nature of this
invention, a communication to me from abroad by Otto Ludwig Phillipp Swiderski
and Emil Capitaine of Leipzig-Plagwitz in the German Empire, Engineers, 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 petroleum motors of a kind in which the vaporiser is in
constant open communication with the cylinder space and in which the air for
combustion does not pass through the vaporiser.
The invention consists, firstly, in an arrangement by which both the petroleum
and air is passed through a single inlet valve the petroleum however taking its
way through a vaporiser heated to a comparatively moderate temperature, the

and secondly in an arrangement by which any suitable quantity of air may be
passed with the petroleum through the vaporiser for the purpose of more con-
veniently starting or driving the motor as well as for preventing premature
ignition of the petroleum in or at the vaporiser.
In the accompanying drawing the invention is shewn applied to the end of the
cylinder of a motor, A being the cylinder, B the cooled combustion space or
chamber, C the vaporiser, D the inlet valve, E the outlet valve aperture.
The vaporiser is in the form of a bent tube, one arm c of which projects
into the combustion chamber and by its outlet c' delivers the petroleum vapour
in the same direction as the entering air. The petroleum is conducted by a
tube i to the inlet valve past which it passes into the vaporiser at y at the time
the inlet valve is opened by the suction of the piston (not shewn) of the motor.
The vapour generated in the vaporiser takes its way along arm c, out at c¹ and
then passes towards the cylinder with the air for combustion as shewn by the
arrows. The peculiar feed to the vaporiser is obtained by narrowing the air
passage at o between the inlet and outlet of the vaporiser.
The ignition of the combustible gaseous mixture is not effected by any particular
igniting arrangement or by contact with hot surfaces but rather by compression as
in the case of the motors known as the "Capitaine" petroleum motors.
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 :
In a petroleum motor the suction past valve D of the petroleum into the
vaporiser simultaneously with the separate passage past the same valve and through
a narrowed passage o of the air for combustion which mixes with the petroleum
vapour from the vaporiser, substantially as described and shewn.
