Improvements in and relating to Oil and Gas Engines.
-
We, ADOLPHUS BARRON, of Rydal Street Works, Leicester, Engineer, and
JACOB JAMES RIDLEY, of 17, Hughendon Drive, Aylestone Road, Leicester,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention consists of improvements in and relating to oil and gas engines
and has particular reference to the means used for vapourizing the oil and igniting
the vapour in an oil engine and also for igniting the charge in a gas engine.
As will be well understood oil and gas engines are actuated by the explosion
of a mixture of petroleum vapour and air or other suitable explosive mixture
from vapourized liquid hydro-carbon or from gas and the object of this inven-
tion is to produce a motor to be operated by these means.
To carry out the invention we provide a vaporizer consisting of an outer
jacket approximately closed at one end and open at the other, the said jacket
being bolted to the engine cylinder by means of a flange formed thereon, part
of the said jacket projecting inside the combustion chamber.
Inside the said jacket is an inner chamber having an outlet into the cylinder
through the end of the before mentioned jacket and also with another opening
into the cylinder through the top or other desired part of the said jacket.
The igniter consists of a tube placed inside the inner chamber of the vaporizer
and the said tube has carried or suspended therein an igniter of porcelain or any
other suitable substance with which the charge is ignited. Formed with or
attached to the outside of said vaporizer may be a cover of any desired shape
having an opening or openings and tube, by means of which a lamp may be
applied to heat the vaporizer or charge in starting. The oil may be supplied to
the vaporizer under pressure or by gravity.
In working, the piston will move forward and take in a charge of air and at
the same time the oil valve will open to allow a measured charge of oil to enter
the vaporizer, and as the piston returns it will compress the charge which will
be fired by the igniter.
When the speed exceeds the normal rate of running, the governor may hold
open the exhaust and allow the oil valve to remain closed.

Improvements in and relating to Oil and Gas Engines.
We, ADOLPHUS BARRON, of Rydal Street Works-Leicester, Engineer, and
JACOB JAMES RIDLEY, of 55, Chestnut Street, (late of 19, Hughendon Drive,
Price 8d.1

page_text: Aylestone Road,) Leicester, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
This invention consists of improvements in and relating to oil and gas engines
and has particular reference to the means employed for vapourizing the oil and
igniting the vapour in an oil engine and also for igniting the charge in a gas
engine.
As is well understood oil and gas engines are actuated by the explosion of a
mixture of petroleum vapour and air, or other suitable explosive mixture from
vapourized liquid hydrocarbon, or from gas, and the object of this invention is
to form a vapourizer or motor to effect the ignition of the charge. The inven-
tion will be clearly understood by the following further description with reference
to the accompanying drawing only so much of an oil or gas engine being shown
as is necessary to clearly illustrate the invention.
Figure 1 is a central sectional elevation through the rear part of the cylinder
of an oil or gas engine showing our invention applied thereto.
Figure 2 is a cross sectional elevation taken on the line a, b, of Figure 1, and
Figure 3 is a sectional plan taken on the line c, d, of Figure 1.
Figure 4 is a sectional view of the igniter detached, showing how the ignition
tube is supported.
In carrying out this invention as 'applied to an oil engine, the jacket A of the
vapourizer is provided with a flange A having holes A therein. The bolts A
pass through the said holes A2 into the end of the cylinder B to hold the
vapourizer in position.
Inside the said jacket A there is an inner chamber C which may be formed
integrally with the said jacket as shown in the drawing, or bolted thereto in any
convenient way.
The said inner chamber Chas an outlet C₁ communicating with the combustion
chamber or cylinder B through the end of the jacket A and an opening C², by
which oil may be supplied to the vapourizer, opposite to an opening B₁ passing
through the jacket B2 of the cylinder B.
An
(see
The said openings C2 B may be placed in the vertical position shown in
Figure 1, or at an angle as found convenient, and the air valve herein-
after mentioned may also be placed at an angle with the cylinder B.
igniter is fixed in the central rear part of and extends into the chamber
Figures. 1 and 3). The said igniter preferably consists of a porcelain tube D,
through which is passed a bolt 1 the latter being held in position in the ignition
tube or chamber by the nuts F, F. Two asbestos washers G, G, or equivalent
means, are interposed between the nut F" and head 12 of the bolt D₁ and the
ends of the said tube D.
As it is desirable to regulate or control the mixture between the combustion
chamber or cylinder B and the inner chamber C of the vapourizer, we provide
a valve H movable to and fro across the opening C₁ before mentioned to close
the said opening during the compression of the charge, i.e., approximately during
one fourth of the cycle. The mechanism for actuating the said valve H consists
of a cam K fixed on the usual shaft K' of the engine, the said shaft being carried
in brackets, one of which L, is shown in Figures 2 and 3. The said bracket L
is provided with a boss L¹ to which is pivotted by the bolt L2 a bell-crank lever M,
its lower horizontal arm carrying a runner M₁ which rides on the periphery of
the cam. K before mentioned. The upper vertical end of the said lever M bears
against and actuates the end of a bolt N which passes inward and engages the
valve H before mentioned.
The inner end of the bolt N has a T head to pass into T shaped slot formed in
the said valve, this arrangement not only being a convenient means of attach-
ment of the two parts, but also allows. of the expansion and contraction of the
vapourizer.
To secure the return of the valve H after it has been pressed inward by the

page_text: lever M, a coil spring O surrounds part of the rod N and is compressed at each
inward stroke between the collar N and the face P¹ of the recess P2 formed in
the gland l'; but, instead of the said coil spring O, the rod N and lever M may
be jointed together in the well-known way. The gland P passes through the
jacket 12 of the cylinder into the jacket A of the vapourizer and a collar No on
the said rod is shaped to fit the end of the gland at each outward stroke of the
valve, i.e. when a charge has been ignited.
The outward end of the vapourizer is enclosed by a cover Q which may be
hinged at Q to the flange A¹, or bolted to the latter.
An opening R is formed in the said cover (preferably in the position shown
in Figure 1) so that a lamp or any other means may be applied to heat the
vapourizer or charge when starting the engine.
In working, the piston moves forward in the direction of the arrow Figure 1,
and takes in a charge of air through a port 133 and air valve B4 opened by any
desired means, and at the same time the oil valve (not shewn) will open to allow
a charge of oil and also a per centage of air to pass through the openings B¹ C
into the chamber C and cylinder B and as the piston returns it compresses the
charge of air and oil vapour, but the valve H being closed during the return
stroke of the piston, the said- charge does not enter the chamber until the
piston has approximately reached the end of its return stroke when the valve H
opens and allows the charge to enter the chamber C, when it is fired by the
igniter and forms the power for driving forward the piston to complete the
cycle.
The engine as is well understood, may be controlled by a governor which will
allow the oil valve to remain closed when the engine exceeds the normal rate
of running. It will be understood for a gas engine that the jacket A is not
required and that the chamber C is open to the combustion chamber or cylinder
of the engine.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In an explosive vapour engine, a vapourizer consisting of a chamber sur-
rounded by a jacket and provided with an inlet for the admission of the oil, and
an opening connecting the inner chamber with the combustion chamber or.
cylinder substantially as described and illustrated in the accompanying drawing.
2. An igniter for an explosive vapour engine, substantially as described and
illustrated in Figure of the accompanying drawing.
3. In an explosive vapour engine the combination with the vapourizer of an
igniter constructed and operating substantially as described and illustrated in
the accompanying drawing.
4. In an explosive vapour engine, the combination with the vapourizer of a
valve for regulating the mixture constructed and operating in the manner sub-
stantially as described and illustrated in the accompanying drawing.
