Improvements in Oil Engines and the like.
I, THOMAS WARSOP of Coniston in the County of Lancashire, Engineer do
hereby declare the nature of this invention to be as follows:-
My improvements comprise a simple and efficient method of vaporising the oil
or other liquid used as the motive force for oil engines and the like; and also a
simple oil lamp for effecting the ignition of the explosive mixture of oil vapour
and air in the motor cylinder.
For this purpose I employ a motor engine-either single or double-acting-
having a cycle of any suitable operation; but preferably one having what is known
as the "Otto" cycle. In connection with the chamber containing the admission
valve to the exploding chamber of the motor cylinder, I have an oil vaporising
chamber, surrounded and heated on the outside by a jacket through which pass
the hot products of combustion exhausted from the motor cylinder. Through the
centre, and from top to bottom of this chamber, I fix a thin tube; within which
burns the lamp for heating the ignition tube to fire the explosive mixture in the
motor cylinder; by this means also the vaporising chamber is heated internally.
Oil in a suitable quantity is admitted into this heated vaporising chamber,
from whence it is drawn by a port or pipe past the air admission valve-where it
is mixed with a suitable supply of air-into the motor cylinder for compression
and explosion in the usual manner.
My improvements in the heating lamp is as follows:-I have an oil reservoir-
fixed at a suitable height above the vaporising chamber, so as to obtain the
requisite fall or head of oil; and from this reservoir depends a pipe fitted with a
controlling tap or valve; and connected at its lower end with a second reservoir
near the level of the motor cylinder. This latter reservoir is filled with small
shot or other suitable material, and from near the bottom of this shot chamber
I have a pipe to convey the oil to a small heating or vaporising chamber placed in
the lamp chimney. The oil is vaporised in this chamber, and passes down from
thence by another pipe leading to the bottom of the lamp chimney, and terminating
in a small burner, where the issuing oil-vapour is burnt, and thus forms the lamp
for heating the ignition tube of the motor cylinder; and for heating the small
chamber wherein oil is vaporised for its own supply.
Before starting the engine, the lamp vaporising chamber is temporarily heated
by burning under it a haud lamp or by other suitable means.

COMPLETE SPECIFICATION.
Improvements in Oil Engines and the like.
I, THOMAS WARSOP of Coniston in the County of Lancashire, 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 :-
My improvements comprise a simple and efficient method of vaporising the oil

page_text: or other liquid used as the motive force for oil engines and the like; and also a
simple oil lamp for effecting the ignition of the explosive mixture of oil vapour and
air in the motor cylinder.
For this purpose I employ a motor engine either single or double-acting, having
a cycle of any suitable operation; but preferably one having what is known as the
"Otto" cycle. In connection with the chamber containing the admission valve
to the exploding chamber of the motor cylinder, I have an oil vaporising chamber,
surrounded and heated on the outside by a jacket through which pass the hot
products of combustion exhausted from the motor cylinder.
Through the centre, and from top to bottom of this chamber, fix a thin tube
within which burns the lamp for heating the ignition tube to fire the explosive
mixture in the motor cylinder; by this means also the vaporising chamber is
heated internally.
Oil in a suitable quantity is admitted into this heated vaporising chamber, from
whence it is drawn by a port or pipe past the air admission valve-where it is
mixed with a suitable supply of air-into the motor cylinder for compression and
explosion in the usual manner.
My improvements in the heating lamp are as follows:-I have an oil reservoir
fixed at a suitable height above the vaporising chamber, so as to obtain the
requisite fall or head of oil; and from this reservoir depends a pipe fitted with a
controlling tap or valve; and connected at its lower end with a second reservoir
near the level of the motor. cylinder. This latter reservoir is filled with small
shot or other suitable material, and from near the bottom of this shot chamber
I have a pipe to convey the oil to a small heating or vaporising chamber placed
in the lamp chimney. The oil is vaporised in this chamber, and passes down from
thence by another pipe leading to the bottom of the lamp chimney, and terminating
in a small burner, where the issuing oil-vapour is burnt, and thus forms the lamp
for heating the ignition tube of the motor cylinder; and for heating the small
chamber wherein oil is vaporised for its own supply.
Before starting the engine, the lamp vaporising chamber is temporarily heated
by burning under it a hand lamp or by other suitable means.
And in order that my said invention may be fully understood and readily carried
out and into effect, I shall now proceed more particularly to describe the same;
and for that purpose shall refer to the several figures on the annexed sheet of
drawings wherein the same letters of reference indicate corresponding parts in all
the figures.
Fig. 1 is a longitudinal sectional elevation of a single cylinder oil motor engine
fitted with my invention.
Fig. 2 is an end elevation of the same engine, partly in section along the
line 1-2 (Fig. 1).
In these views D is the cylinder of a single acting oil engine fitted with the
piston D¹, and turning the crank shaft D' and fly wheel D3 by the connecting
rod D, by the explosion of a suitable mixture of vaporised oil and air in the
exploding or combustion chamber E. A is the admission valve to the combustion
chamber E, and connected to the valve chamber A¹-surrounding valve A-I have
an oil vaporising chamber B having the port P connecting same with the chamber A¹.
Chamber B is surrounded and heated on the outside by the jacket C, along which
pass the heated products of combustion from cylinder Ď, past the exhaust valve G
through chamber or jacket C, and thence away to the atmosphere by exhaust
pipe C F is a thin metal tube passing from top to bottom through the chamber B-
and in some cases lined with asbestos. Lis the lamp for heating the ignition
tube I, which fires the explosive mixture in chamber E and cylinder D; and the
heat from lamp L also heats tube F, and vaporises the oil passing into chamber B
and pocket B of same.
His an oil reservoir, fixed at a suitable height above the chamber B, 80 as to
obtain a sufficient head of oil, fitted with the supply pipe S and controlling tap H.
Pipe S is connected at its lower end with a second reservoir R placed below

page_text: chamber B, and having another supply pipe S¹ to convey the oil therefrom to the
small vaporising chamber M placed in the lamp chimney L¹.
The oil is vaporised in this chamber by the lamp L-the flame from which
impinges on the outside of same-and receives its supply of vaporised oil for
combustion by the pipe S³.
Thus the lamp L vaporises oil in chamber M for its own combustion, heats the
tube F to assist in vaporising the oil for use in the motor cylinder D, and also
heats the ignition tube I for firing the explosive compound in chamber E. For
starting the engine at first-when all is cold-I usually heat the vaporising
chambers B and M, and ignition tube I by holding an ordinary hand lamp in the
lamp chimney L'.
Oil in a suitable quantity is admitted into the chamber B from reservoir H past
the regulating valve H into funnel H³, pipe H, chamber A', and port P; and
after being vaporised in chamber B is drawn back again through port P into
chamber A', where it is mixed with a suitable supply of air; and thence past
admission valve A into the combustion chamber E for compression and explosion
in the ordinary manner.
In some cases I may fill or partially fill reservoir R with small shot or other
suitable material to control the supply of oil, and to prevent back firing and other
eventualities.
The exhaust valve G is opened and closed at the required times by the usual
meaus from the crank shaft D².
In other cases I may form one or more grooves of suitable form on the outside
of tube F to receive the oil and assist the vaporisation thereof; and sometimes
I may use a pump to supply oil to the motor in place of having a fall or head
of oil.
My invention is also applicable to motors having two or more cylinders, and
wherever oil is required to be vaporised for motor or other purposes.
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 :-
1st. In oil motor engines the method of vaporising the oil required for combustion
therein by means of passing the heated products of combustion therefrom around
the vaporising chamber in combination with the heating lamp for effecting ignition
substantially as hereinbefore described and shown in the drawings herewith.
2nd. The construction of an oil motor engine which works by means of oil
vaporised in a chamber by the heated products of combustion passing around this
chamber on leaving the motor, substantially as described herein.
3rd. In oil motor engines the construction of a heating and ignition lamp having
a vaporising chamber supplied by a fall of oil, and from whence oil vapour passes
to feed the heating lamp, which in turn heats the chamber for vaporising oil for
its own combustion, substantially as hereinbefore described and shown in the
drawings herewith.
4th. In oil motor engines the combination of an exhaust heated vaporiser to
supply vaporised oil for combustion in and in combination with an oil motor having
one or more motor cylinders, all for the purposes mentioned and substantially as
set forth herein and shown in the drawings herewith.
5th. In oil motor engines the arrangement and combination of parts as shown
in Figs.
and 2 for the purposes mentioned and substantially as hereinbefore
described and shown in the drawings herewith.
