PROVISIONAL SPECIFICATION.
Improvements in or connected with Vaporizers of Oil and other
similar Engines.
I, JOHN STRINGER HINCHLIFFE of Monk Street, Wakefield, in the County of
York, Engineer, do hereby declare the nature of this invention, to be as follows
.
The object of my invention is to construct vaporisers for oil and other similar
engines in a simple and efficient manner; and vaporisers so constructed are als
applicable to existing gas engines when it is desired to convert same into oil
engines.
According to my invention, I construct the vaporiser in a cylindrical form having
a flanged base for connecting same to the engine. An ignition tube, which may
be of the ordinary description, passes up through the centre of the cylindrical case;
and an opening at the base of the said case formed to provide air to the ignition
tube, the upper portion of the case being open to admit of a through passage of
air. A jacket, which is formed on the casing, rises spirally until it meets with a
passage leading to the feeding valve of the engine situated at the lower part of tho
cylindrical case; and an inlet valve which may suitably be of the mushroom type,
is provided at the base of the jacket for the admission of air. At the upper enu
of the jacket an inlet is provided for the admission of oil to be vaporised, and these
air and oil valves may be actuated by any suitable means in order to regulate the
supply to the exact amounts required.
The heat from the flame employed to heat the ignition tube, heats the cylindrical
case, and on the suction, caused by the action of the piston, taking place, air and oil in
the required quantities are admitted to the jacket. As the oil is admitted it comes
in contact with the jet of air admitted at the lower end of the jacket, which action
combined with the heat of the jacket stratifies and vaporises the oil. The vapour
thus formed ascends in the spiral chamber, where it becomes superheated, and it
then passes down through the passage to the combustion chamber where it mixes
with a supply of air which is admitted through a valve at the required time, and
the explosive mixture thus formed is then ignited by the ignition tube in the
ordinary way.

the same is to be performed to be particularly described and ascertained in and by

CULTY CLU
In order that my invention may be clearly understood. I will proceed to describe
same with reference to the accompanying drawings in which similar letters refer to
like parts in all the figures.
Figure 1, is an end elevation partly in section, showing my invention applied to
an engine and Figure 2 is a longitudinal section of same.
i
Figure 3, is a sectional end elevation, and Figure 4 is a longitudinal view partly
in section, of a slight modification of my invention.
According to my invention, the vaporizer which is of cylindrical form is
constructed in two parts A, and B, which are bolted or otherwise secured together
through their flanges A, B, and 21 flange C is provided on the part B of the
vaporizer for the purpose of attaching same to the engine. D is the ignition tube,
which passes up through the centre of the cylindrical case, and the base of the
vaporizer is open to allow of the through passage of a current of air for the flame
of the combustion tube. E is a jacket which rises in a spiral form round the
vaporizer, and in the base of the said jacket I provide a series of partitions or
walls F which prevent the flowing of liquid along the base of the jacket E. Gis
an inlet which is connected with the oil tube H, which latter is connected with
an oil pump or other suitable supply, which feeds oil to the jacket E at the
required time. J, J, are valves for supplying air to the jacket when the pressure
within same is below that of the atmosphere and the direction of these air inlets
is such as to cause the air and the oil to come into contact with each other as they
enter the jacket E. K is a passage which connects the interior of the jacket
with the feeding valve L of the engine, which latter admits the explosive mixture
to the cylinder at the required time at the same time preventing the force of the
explosion being felt at the jacket E.
The heat from the flame employed to heat the ignition tube D, heats the interior
of the vaporizer A, B, and on the engine piston moving forward, the suction so
caused draws air through the valves J, the valve L having been opened by a hit
and mis device or other mechanical gearing, whilst at the same time a given quantity
of oil is admitted to the jacket E by means of the oil supply pipe H. As the oil is
admitted it comes into contact with the jets of air, which action combined with the
heat of the jacket stratifies and vaporizes the oil. The vapour thus formed
ascends in the jacket E where it becomes superheated, and it is drawn down through
the passage K and valve L to the combustion chamber, where it mixes with a
supply of air which is admitted through a valve at the required time, and the
explosive mixture thus formed is ignited by the ignition tube in the ordinary way.
When the suction takes place in the vaporizer, the partitions F prevent any liquid
oil which may be in the base of the jacket, from being drawn up along the base of
the jacket into the passage K, as the said oil is forced to rise in a form of vapour
in order to reach the passage K.
In the modification shown at Figures 3 and 4, the ignition tube is shown in a
horizontal position, and this adaption is particularly suitable for small engines.
At Figure 5 the air valve J is shown in section, and the upper surface of the said
valve is provided with a perforated cover J, for the purpose of keeping the said
valve free from dust. If desired the whole of the vaporizer A, B, may be covered
with a casing for the purpose of retaining the heat, and also for protecting the
vaporizer from contact with foreign substances. By disconnecting the flange C
from the engine, and attaching a gas connection, the engine may be readily converted
into a gas engine.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I claim is
1. In an apparatus for supplying an engine with vaporized oil mixed with air, the
jucket E havino suitable oil and air inlets” substantially as set forth.

page_text: 2. In an apparatus for supplying an engine with vaporized oil mixed with air,
the jacket E having partitions F at the base of same, the oil inlet G, the air inlet
valves J, J, and the passage K, all arranged substantially as and for the purposes
set forth.
3. The vaporizer constructed in two parts A and B, which are secured together
