Improvements in or applicable to Oil Motor Engines,
I, WALTER JAMES BATES, of the Firm of W. J. Bates and Company, of Victoria
ron Works, Denton, in the County of Lancaster, Engineers and Ironfounders,
o hereby declare the nature of the said invention, to be as follows:--
My invention relates to arrangements and combinations for supplying the oil
o be vapourised, and in vapourising it by the exhaust products of combustion
from the cylinder of the engine, using a lamp for vapourising only at starting
the engine.
My invention consists in combinations and arrangements in which pumps com-
monly used are dispensed with for supplying the oil to the cylinder of the engine
and also in which the lamp commonly used is dispensed with for vapourising
the oil except at starting, and until a moderate load has been put on the engine,
using instead the heated products of combustion from the engine.
The arrangements and apparatus are applied to the outer end of the cylinder
of the engine, which is arranged with an ordinary cone lifting valve closed by
a spring for opening and closing the outlet from the cylinder for the exhaust
products of combustion, such exhaust valve being actuated by a cam or tappet,
and lever in the usual manner.
Above the .exhaust valve chamber, there is another chamber which together
with the exhaust chamber forms the chamber for vapourising the oil, and at the
upper end and closing that end of the vapourising chamber, there is a cone valve
on a spindle opening inwards to the vapourising chamber (which valve will be
hereinafter termed the air and oil valve) as it closes the lower end of a small
chamber into which air can enter to mix with the oil or its vapour, and also
into which the oil can enter through a small hole, which small hole communicates
by a pipe bent into a vertical position with a cistern for oil below it.
The lower end of this oil pipe is screwed into a part in which a ball or other
suitable valve is arranged, so that oil drawn from the oil cistern into the pipe
will be prevented by the ball or other valve from returning to the cistern,
thereby doing away with such an uncertain and regular supply such as is
0 given by a gravity feed, as the cistern containing the oil is below the cylinder.
At the upper part of this vertical pipe, a cone valve is arranged, the opening
and closing of which is regulated by a screw so that by means of this valve the
supply of oil may be adjusted to the requirements of the engine.
Upon the outer end of the spindie of the oil and air valve a spring is arranged
35 to hold up the valve against its seating with sufficient force, but it opens to the
suction of the piston of the engine when the oil and air are to pass into th
cylinder.
There is or may be a dish round the air and oil valve spindle below the poin
where the oil enters the chamber which catches the oil and it spreads over th
40 bottom of the dish and passes through small holes which thus distributes th
oil in the air and oil chamber.
The heated products of combustion in passing out from the cylinder com

the suction of the piston of the engine takes place a partial vacuum is formed
which draws oil from the cistern up the vertical pipe and past the regulating
valve to the air and oil chamber.
At the upper end of the pipe for the oil supply, there is a cavity or cup
through which a little oil may be supplied to be vapourised before starting the
engine.
Alongside and connected direct to the vapouriser is a common iron ignition
tube under which the starting lamp is placed this heats the tube at the same
time as the vapouriser, and ensues the certain firing of the first vapourised
charges of oil.
The oil is timed by an ordinary mushroom valve which is actuated by the
governor, which ensues the oil being supplied in exact proportion to the amount
of work taken from the engine.
If the oil timing or regulating valve is not opened by the action of the
governor, then the suction only acts on the air valve, thereby missing an
explosion as required.
When started the lamp is dispensed with, as then the heated exhaust products
from the cylinder are sufficient after the engine has started.

improvements in or applicable to Oil Motor Engines.
I, WALTER JAMES BATES, of the Firm of W. J. Bates and Company, of Victoria
Iron Works, Denton, in the County of Lancaster, Engineers and Ironfounders,
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 invention relates to arrangements and combinations for supplying the oil
to be vapourised, and in vapourising it by the exhaust products of combustion
from the cylinder of the engine, using a lamp for vapourising only at starting
the engine.
My invention consists in combinations, and arrangements in which pumps com-
monly used are dispensed with for supplying the oil to the cylinder of the engine
and also in which the lamp commonly used is dispensed with for vapourising
the oil except at starting, and until a moderate load has been put on the engine,
using instead the heated products of combustion from the engine.
The arrangements and apparatus are applied to the outer end of the cylinder
of the engine, which is arranged with an ordinary cone lifting valve closed by
a spring for opening and closing the outlet from the cylinder for the exhaust
products of combustion, such exhaust valve being actuated by a cam or tappet,
and lever in the usual manner.
Above the exhaust valve chamber, and on one side of it, there is another
chamber which together with the exhaust chamber forms the chamber for
vapourising the oil, and at the upper end and closing that end of the vapourising
chamber, there is a cone valve on a spindle opening inwards to the vapourising
chamber (which valve will be hereinafter termed the air and oil valve) as it
closes the lower end of a small chamber into which air can enter to mix with
the oil or its vapour, and also into which the oil can enter through a small hole,

hich small hole communicates by a pipe bent into a vertical position
stern for oil below it.
The lower end of this oil pipe is secured into a part in which a ball or other
uitable valve is arranged, so that oil drawn from the oil cistern into the pipe
ill be prevented by the ball or other valve from returning to the cistern,
hereby doing away with such an uncertain and irregular supply such as is
iven by a gravity feed, as the cistern containing the oil is below the cylinder.
At the upper part of this vertical pipe, a cone valve is arranged, the opening
nd closing of which is regulated by a screw so that by means of this valve the
upply of oil may be adjusted to the requirements of the engine.
Upon the outer end of the spindle of the oil and air valve a spring is arranged
to hold up the valve against its seating with sufficient force, but it opens to the
suction of the piston of the engine when the oil and air are to pass into the
cylinder.
There is or may be a dish round the air and oil valve spindle below the point
where the oil enters the chamber which catches the oil and it spreads. over the
bottom of the dish and passes through small holes which thus distributes the
oil in the air and oil chamber.
The heated products of combustion in passing out from the cylinder come
into the vapourising chamber and heat it so that the oil is vapourised, and when
the suction of the piston of the engine takes place a partial vacuum is formed
which draws oil from the cistern up the vertical pipe and past the regulating
valve to the air and oil chamber.
At the upper end of the pipe for the oil supply, there is a cavity or cup
through which a little oil may be supplied to be vapourised before starting the
engine.
Alongside and connected direct to the vapouriser is a common iron ignition
tube under which the starting lamp is placed this heats the tube at the same
time as the vapouriser, and ensues the certain firing of the first vapourised
charges of oil.
When started the lamp is dispensed with, as then the heated exhaust products
from the cylinder are sufficient after the engine has started.

a, in dotted line represents part of the engine cylinder, from the end of which
there is a passage a¹, going through the exhaust valve chamber b, and to th
50 vapourising chamber c.
bis
The exhaust valve chamber has a seating formed in its lower side for a con
valve b¹, opening inwards, this valve (see Fig. 1) being upon the upper end o
a stem, passing through a hole and boss on the lower side of the exhaus
valve chamber, which guides its vertical opening and closing movements.
A disc 63, is secured on the lower part of the stem of the valve and betwee
this disc and the boss on the casting, a helical spring b, is arranged, which wi
act to close the valve after it has been lifted.

page_text: From the underside of the cone valve there is a passage 6, which forms the
outlet for the exhaust products from the engine cylinder a.
The upper side of the cavity for the exhaust valve is closed by a lid 66, secured
by screws thereto, which thus gives ready access to the exhaust valve.
The exhaust valve is lifted or opened by a lever , having its fulcrum on a
stud d', in a bracket or arm, from the exterior of the casting, one end of
the lever comes under the end of the stem 2, of the exhaust valve, and the other
end carries an anti-friction bowl 3, which is acted upon by a cam or tappet, "d",
on a side shaft, arranged and driven by the engine in any ordinary, manner.
On the upper side of this lever d, there is a projection, upwards having
notch in it on one side.
As shown in Fig. 1, the notch is clear of the lower end of the vertical arm
of a bell crank lever, having its fulcrum on a stud 8, in a flanged, from
the cylinder or a bracket therefrom. But the other horizontal arm of the bell
crank lever is connected with the lower end of a rod ³, by adjusting screw
nuts, this rod being connected with and actuated by any usual and ordinary
centrifugal governor driven by the engine, so that when the speed of rotation
has increased above the point fixed upon, the rod d, will ascend and cause the
end of the vertical arm of the bell crank lever d, to come towards the pro-
jection d, and catch upon the notch upon its side, when the cam acts to open
the exhaust valve 1 by this means the lever d, is prevented from making its
return movement and thus the exhaust valve is held open on one or more rotations
of the engine.
But when the speed of the engine diminishes, the governor will act upon the
bell crank lever d, to withdraw its end away from the notch when the cam
acts upon the lever d, when at its greatest distance from the bowl .
e, is an ordinary ignition tube screwed into the lower end of the oil vapourising
chamber c. This chamber is heated only by a lamp placed under it at the starting
of the engine.
The part, having the air and oil valve is secured by flanges and bolts or
screws to the upper part of the oil vapourising chamber c.
The lower end of this part c¹, has a seating formed on it for a cone valve ²,
on the lower end of a stem c³; passing and guided through a hole in a boss on
the upper side of the part c¹. At the upper end of the stem e, of the valve a
disc is secured; and also free to rotate upon the stem a sleeve c, is arranged,
the exterior boss part of which is screw threaded, and upon which a disc c6, can
screw up and down.
This disc 6, is the abutment for the upper end of a helical spring c', the other
end of which rests against the part e, from which the boss extends.
It is by this arrangement that the tension of the spring c, acting to close the
valve 2, can be regulated to suit the vacuum and the oil supply required.
There are a number of side passages or holes, through the sides of the
part c¹, which allow air to enter to mix with the oil vapour. If desired these
holes may be made with plugs so that one or more may be stopped to adjust
the supply of air.
At one side of the part, there is a hole and boss for the oil supply pipe f
which may pass upwards from the oil supply cistern f¹, as shown in Figs. 1
and 5.
This oil supply pipe is made with a coil f, either in the position shown or
higher up the oil supply pipe.
The lower end of the oil supply pipe screws into a lid or cover ³, (see Fig. 4)
which has a boss on its lower side that fits air tight into a recess in a plate f*,
below and can be secured thereto by screws.
In the recess a seating is formed for a ball valve, by preference, the inlet fö,
to this ball valve being on the under side of the lower plate f, which is
arranged to stand a little above the bottom of the oil supply cistern f¹, to give
free admission to the oil from the cistern to the valve.

page_text: Fig. 6, shows on an enlarged scale a junction elbow at the upper part of the
il supply pipe f, coming between the vertical (f) and horizontal (F) parts of
he pipe.
In this elbow g, there is a seating formed for a cone valve y', with a three
winged stem to guide it in its movements in opening and closing. The extent
screw, which can
to which the valve shall open is regulated by a set
locked by a screw nut g³, when adjusted.
be
There is an annular cavity ca, in the top of the part c', round its upward boss,
into which oil is poured for starting the engine, and it flows from this cavity
through a small hole cb, into the chamber of the valve for oil and air, when it
gets vapourised and is drawn into the cylinder as its first explosive charge on
starting.
When the speed of the engine increases enough to move the bell crank lever dễ,
to the extent fixed upon, it acts to prevent the exhaust valve 6', from closing,
and this admits air through the exhaust valve, and then as there is no vacuum
or one not sufficient to open the oil and air valve ², against the tension of its
spring e, no oil and air is supplied, and an explosion is missed and the engine
then passes through one Otto cycle of suction, compression, explosion and
exhaustion without oil or air and explosion.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The supplying of oil to an oil motor engine from a cistern by means of
the vacuum tormed in the engine cylinder during its suction stroke substantially
as herein before described and illustrated by the drawings.
2. The vapourising of the oil supplied by the heat from the exhaust products
which fill the oil vapourising chamber before leaving at the outlet for exhaust
substantially as hereinbefore described and illustrated by the drawings.
3. The combination and arrangement of the oil and air valve, with the oil
supply cistern and exhaust valve substantially as herein before described and
illustrated by the drawings.

4. The combination of the mechanism referred to in Claim 3 with
regulating the supply of oil by the suction of the vacuum, substantially as herein-
before described and illustrated by Fig. 6, of the drawings.
5 5. The combination and arrangement of mechanism for actuating the exhaust
valve and controlling it by a governor, the supplying of the oil and air by the
