"Improvements in Oil-Motors."
We, ISAAC CORDINGLEY, THOMAS WILLIAM CORDINGLEY, and JOHN SMITH,
Engineers; of Carlshalton in the County of Surrey, do hereby declare the nature of
this invention to be as follows:
Our invention relates to the cooling of the cylinder with an air-jacket and by
the same process preparing the air and oil for said motors for giving a ready and
spontaneous ignition, and consists in first drawing cold air through the said
jacket by suction of the piston, or forcing said air through by a fan-like action
taken off the rotary motion of the fly-wheel, thus keeping the cylinder cool and by
the same process heating the air which is used for motive power, and further, by
this said' method, fully preparing the air for readily mixing with the air and oil
that have been previously drawn in by the usual valves or methods, and giving a
maximum explosive effect by spontaneous ignition, thus making our vaporiser
direct acting without the intervention of tubes, oil-pumps, timing valves or con-
tinuous light from any lamp.
According to our invention air is drawn through the jacket at the first out-
stroke, by the methods above described, and on and around the explosion chamber
and through the main air-valve into the motor cylinder. At the same time a small
quantity of air and oil is drawn through a passage in the valve-block and over the
explosion chamber into the hot chamber (which is heated by a lamp at starting
only) and from there into the motor cylinder, there mixing with the main air
which has been heated and prepared as aforesaid.
The first instroke compresses this diluted and now highly explosive mixture into
the explosion chamber and hot chamber, which last-named chamber becomes, by
the above method, a vaporiser and spontaneous igniter, the next or second out-
stroke as a result being explosion plus expansion, while the second in-stroke is
for exhaust in the usual form.

We, ISAAC CORDINGLEY, THOMAS WILLIAM CORDINGLEY and JOIN SMITH,
Engineers, of Carshalton, in the County of Surrey, 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:-
Our invention relates to improvements in oil motors and has for object to provide
means for cooling the cylinders and for giving the maximum effective explosions
by spontaneous ignition.

page_text: And in order that our invention may be fully understood we will describe same
with reference to the accompanying drawings and letters and figures of reference
marked thereon, 'that is to say:
Fig. 1 is a cross sectional elevation, and
Fig: 2 a sectional plan of an oil motor Cylinder provided with our improvements.
This our invention consists essentially in drawing cold air through the cylinder
jacket by suction of the piston when on its out stroke or forcing said air through
by a fan like action taken off the rotary motion of the flywheel thus keeping the
cylinder cool without water, and by this process heating the air which is used
for the motor power and fully preparing the air for ready mixing with the air and
oil that have been previously drawn in by the usual motliod and giving a maximum
explosive effect by spontaneous ignition, thus making our vaporizer direct acting
without the aid of tubes, oil pumps, timing valves, or even a continuous light from a
lamp.
The operation is as follows:-
By either of the methods above mentioned air is drawn into the jacket at the
first outstroke of the piston at hole, a circulating. through jacket & around the
cylinder e then through outlets d into jacket e ovdi the explosion chamber c', and
through the main air valve f into motor cylinder.
At the same time a small quantity of air and oil is drawn from over explosion
chamber at g turough passage h in valve block thence through the oil and air
mixing valve i into the hot chamber & which is heated by a lamp at starting only
for a few minutes and from there into motor cylinder there mixing with main air,
which has been heated and prepared as aforesaid.
The first instroke of piston compresses this diluted and highly explosive mixture.
into the explosion chamber e and hot chamber which last named chamber
becomes by the above method a vaporizer and spontaneous igniter.
The second outstroke of piston is the explosion plus expansion, and the second-
justroke is used for exhaust in the usual form, in the drawings showing exhaust
valve, and m the oil pipo.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:..
In oil motors the method of, and means for cooling the cylinder and giving the
maximum effective explosions by spontaneous ignition substantially as herein-
before described and shewn.
