PROVISIONAL SPECIFICATION.
Improvements in Portable Petroleum or Liquid Fuel Engines.
We, THOMAS BELL and JOHN RICHARDSON, both of the firm of Robey and
Company, Globe Works, Lincoln, in the County of Lincoln, Engineers, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to an improvement in the arrangement and construction of
portable petroleum engines, and its object is to combine the water tank and oil
reservoir in a more sightly and convenient manner than hitherto.
In carrying our invention into effect we construct a cylindrical reservoir to
contain water and petroleum, and we mount this reservoir upon wheels. Upon the
upper part of the reservoir we mount the engine.
In carrying the invention into practice we construct a cylindrical reservoir which
we divide into two parts. The larger division contains cooling water which is
pumped through the water jacket of the engine by a suitable pump. The smaller
division contains petroleum or other liquid fuel which is pumped into the
combustion chamber. To prevent any possibility of the oil or petroleum contained
in the oil division from becoming admixed with water leaking from the water
division we prefer to arrange a double partition with a space open to the atmosphere
between so that leakage from either division escapes.
Sometimes we dispense with the double partition and insert in the oil division a
petroleum tank from which we pump the hydrocarbon to feed the engine.
Suitable inlet and outlet arrangements are provided for petroleum and water,
and when we use the separate petroleum tank we provide a door to the oil division
to obtain ready access to the said tank.
The cylindrical reservoir is made sufficiently strong to carry the engine and it is
mounted on four wheels, and supplied with horse trams and other gear in a manner
similar to portable steam engines.

COMPLETE SPECIFICATION.
Improvements in Portable Petroleum or Liquid Fuel Engines.
We, THOMAS BELL and JOHN RICHARDSON, both of the firm of Robey and
Company, Globe Works, Lincoln, 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 :-
Our invention relates to an improvement in the arrangement and construction of
portable petroleum engines, and its object is to combine the water tank and oil
reservoir in a more sightly and convenient manner than hitherto.
Referring to the two accompanying sheets of drawings, Figures 1 and 2 (Sheet 1)
show one mode of carrying the invention into effect, while Figures 3, 4, and 5
(Sheet 2) show a modification.
Figure is an external elevation of an engine arranged according to our
invention.
Figure 2 is a longitudinal section showing another arrangement of oil reservoir.
Figure 3 is an external elevation of a portable petroleum engine to which our
invention is applied.

page_text: Figure 4 is an end elevation corresponding to Figure 3, and
Figure 5 is a plan corresponding to Figure 3.
In carrying our invention into effect we construct a cylindrical reservoir A to
contain water and petroleum, and we mount this reservoir upon wheels G, F. Upon
the upper part of the reservoir we mount the engine D.
We construct a cylindrical reservoir A divided into two parts B and C. The
larger division B contains cooling water which is pumped through the water jacket
of the engine by a suitable pump as D. The smaller division C contains petroleum
or other liquid fuel which is pumped into the combustion chamber, which chamber
is partly indicated at E. To prevent any possibility of the oil or petroleum,
contained in the oil division from becoming admixed with water leaking from the
water division we prefer to arrange a double partition C₁ B¹ with a space open to
the atmosphere between so that leakage from either division escapes.
Sometimes we dispense with the double partition and insert in the oil division C
a petroleum tank as C² (see Figure 2) from which we pump the hydrocarbon to feed
the engine.
Suitable inlet and outlet arrangements are provided for petroleum and water, and
when we use the separate petroleum tank C2 we provide a door as C³ to the oil
division to obtain ready access to the said tank.
The cylindrical reservoir A is made sufficiently strong to carry the engine and it
is mounted on four wheels, and supplied with horse trams and other gear in a
manner similar to portable steam engines.
Figures 3, 4 and 5 show a modification of the hereinbefore described arrangements
and here the greater part of the vessel A is used to contain water while the
petroleum vessel C is bolted on below the cylindrical vessel A.
Similar letters are used to indicate similar parts as at Figures 1 and 2.
The exhaust gases are discharged up the chimney L.
The water circulating pump is shown at D, and the oil pump at M, both pumps
being driven from the shaft N as is usual with "Otto" cycle engines.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is-
1. A portable petroleum engine in which the engine is mounted on a cylindrical
reservoir, which reservoir is divided to contain water and petroleum or other liquid
fuel and is mounted on wheels, substantially as hereinbefore described and illustrated
in the drawings annexed.
2. The arrangements of portable petroleum engines as illustrated at Figures 1, 2,
3, 4, 5 and 6 of the accompanying drawings and hereinbefore described.
Dated this 4th day of January 1893.
