Improvements in or connected with Oil Engines and Means for
Atomizing the Oil Supply thereto.
We, WILLIAM THOMAS BELL, of "Mulgrave," St. Catherines, Lincoln, and
AMOS WARREN, of 168, West Parade, Lincoln, both in the County of Lincoln,
Engineers, do hereby declare the nature of this invention to be as follows:-
The object of this invention is the improvement of the methods of working oil
engines by means of atomizing the oil in the interior of the engine, and consists:
1. In the use or employment of an auxiliary cylinder either fixed or capable
of being easily removed from the power cylinder.
2. The use or employment of an atomizer of star shape or other suitable form
as an addition to the power cylinder, said star shaped atomizer acting at the same
time as igniter for the explosion charge.
To effect this, an auxiliary cylinder is provided at the end of the engine cylin-
der, or in any other convenient position and either fixed or so arranged that it
can be removed with ease for cleaning or other purposes.
At the end of this cylinder nearest the piston, the atomizer is placed consisting
of a star shaped piece of cast iron, or other metal, of which the outer diameter
is the same as the internal diameter of the auxiliary cylinder but this can be varied
at will.
At the opposite end of the auxiliary cylinder to the atomizer is placed an oil
injection nozzle to which oil is supplied under pressure from a pump or other
sources. The oil on being admitted at pressure from the nozzle dashes against the
central part of the atomizer and is split up. The auxiliary cylinder is thus filled
with oil very finely atomized and the amount of heat generated by the working
of the engine is sufficient to effectually vaporise the oil even if of high specific
gravity. The auxiliary cylinder forms thus a supply of vaporised oil for admit-
tance to the working cylinder, air being admitted to this latter cylinder in the
usual manner and the products of combustion exhausted in the same way.
The action of the engine is as follows:-On the outstroke of the engine, air
is drawn in to the working cylinder through the air valve, and at the same time
the vaporised oil rushes through the openings of the star shaped atomizer and
mixes with the air to form an explosive mixture. On the instroke of the piston,
this charge is compressed and at the right moment exploded by contact with the
heated points of the atomizer, the explosion generating sufficient heat to bring
these points to the necessary temperature.

We, WILLIAM THOMAS BELL, of Mulgrave," St. Catherines, Lincoln, and
AMOS WARREN, of 168, West Parade, Lincoln, both in the County of Lincoln,
Engineers, 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:
The object of this invention is the improvement of the methods of working oil
engines by means of atomizing the oil in the interior of the engine, and consists:
1. In the use or employment of an auxiliary cylinder either fixed or capable
of being easily removed from the power cylinder.
2. The use or employment of an atomizer of star shape or other suitable form

To effect this, an auxiliary cylinder is provided at the end of the engine cylin-
der, or in any other convenient position and either fixed or so arranged that it
can be removed with ease for cleaning or other purposes.
At the end of this cylinder nearest the piston, the atomizer is placed consisting
of a star shaped piece of cast iron, or other metal, of which the outer diameter
is the same as the internal diameter of the auxiliary cylinder but this can be varied
at will.
At the opposite end of the auxiliary cylinder to the atomizer is placed an oil
injection nozzle, to which oil is supplied under pressure from a pump or other
sources.
The oil on being admitted at pressure from the nozzle dashes against the cen-
tral part of the atomizer and is split up. The auxiliary cylinder is thus filled
with oil very finely atomized, and the amount of heat generated by the working
of the engine is sufficient to effectually vaporise the oil, even if of high specific
gravity.
The auxiliary cylinder forms thus a supply of vaporised oil for admittance
to the working cylinder, air being admitted to this latter cylinder in the usual
manner and the products of combustion exhausted in the same way.
The action of the engine is as follows:-On the outstroke of the engine, air
is drawn into the working cylinder through the air valve, and at the same time

On the instroke of the piston, this charge is compressed and at the right moment

ating sufficient heat to bring these points to the necessary temperature.
Our invention will be understood from the annexed drawings.

Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is: -
1. Providing an oil engine with an auxiliary cylinder C and an oil atomizer A
of star shape with openings H within the cover B of the main or power cylin-
der I, as specified.
2. In an oil engine, the combination of an auxiliary cylinder C surrounded by
an exhaust cylinder E, an oil atomizer A with openings H between same and
the power cylinder I, the parts being in relation to each other in the manner
shown at Figure 7 of the drawings annexed.
