PROVISIONAL SPECIFICATION.
Improvements in Semi-portable Petroleum or Liquid Fuel Engines.
We, THOMAS BELL and JOHN RICHARDSON, both 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 improved construction and arrangement of semi-
portable petroleum engines, and its object is to combine the water tank, oil reservoir
and exhaust chamber with the engine in a more convenient and effective manner
than hitherto.
In carrying our invention into effect we construct a cylindrical reservoir which
we devide into three parts, one division serves to contain water for cooling purposes,
one serves to contain oil or an oil reservoir, and one serves to silence the exhaust as
discharged from the engine. We mount this cylindrical reservoir above the engine
bed upon suitable stools or castings, and the petroleum engine occupies the space
under the said reservoir in a manner similar to the well known "under type" steam
engine.
The engine cylinder and bed is preferably bolted to a separate bed plate which
carries the reservoir, but this bed plate and the engine bed may be cast in one, if
desired.
The exhaust pipe from the petroleum engine cylinder is preferably carried through
the bed plate and then through one of the castings or supports carrying the cylin-
drical reservoir. This casting may be made hollow to conceal the pipe.
The air inlet may be either taken from the engine bed or from an air inlet
chamber also forming part of or contained within the reservoir, and it may be taken
from an air chamber adjoining the exhaust chamber when it is desired to heat the
air to assist in vaporizing the oil.
The exhaust gases are preferably discharged by a chimney or funnel from the
exhaust chamber.
"
In this manner we construct an "under type" semi-portable petroleum engine
which resembles very closely in outward appearance the well known "under type
steam engine.
Louvres or perforated plates may be applied within the exhaust or silencing
chamber.
With the herein before described arrangement of reservoir above the engine no
circulating pump is required to cause the water to flow through the water jacket as
the said flow or circulation will occur by convection.
Sometimes we place lime or other suitable material in the exhaust chamber.upon
trays or otherwise so disposed as to give a large absorbing surface in order to
absorb the noxious gases from the exhaust and so do away with any objectionable
smell.

Improvements in Semi-portable Petroleum or Liquid Fuel Engines.
We, THOMAS BELL and JOHN RICHARDSON, both 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 improved construction and arrangement of semi-
portable petroleum engines and its object is to combine the water tank, oil reservoir
and exhaust chamber with the engine in a more convenient and effective manner
than hitherto.
Referring to the accompanying sheet of drawings:
:-
Figure 1 is a side elevation, Figure 2 a plan and Figure 3 an end elevation of an
engine constructed in accordance with our invention.
In carrying our invention into effect we construct a cylindrical reservoir A which
we divide into three parts, and sometimes into two parts A and B'; one division A
serves to contain water for cooling purposes, one serves to contain oil or an oil
reservoir, and one B serves to silence the exhaust as discharged from the engine.
In the illustrations shown wo place an oil reservoir in the engine bed but we some-
times divide the cylindrical chamber A into two parts one of which contains oil or
an oil reservoir. We mount this cylindrical reservoir A B above the engine bed F
upon suitable stools or castings and the petroleum engine C occupies the
under the said reservoir in a manner similar to the well known "under type" steam
engines.
space
The engine cylinder and bed is preferably bolted to a separate bed plate F which
carries the reservoir A B but this bed plate and the engine bed may be cast in one
if desired.
The exhaust pipe from the petroleum engine cylinder is preferably carried through
the bed plate and then through one of the castings or supports carrying cylindrical
reservoir. This casting may be made hollow to conceal the pipe. In Figures 12
and 3 the exhaust pipe is shown at E and it passes into the exhaust chamber B as
indicated.
The air inlet may be either taken from the engine bed or from an air inlet
chamber also forming part of or contained within the reservoir and it may be taken
from an air chamber adjoining the exhaust chamber when it is desired to heat the
air to assist in vaporizing the oil.
The exhaust gases are preferably discharged by a chimney or funnel G from the
exhaust chamber. In this manner we construct an "under type" semi-portable
petroleum engine which resembles very closely in outward appearance the well
known "under type" steam engine.
Louvres or perforated plates may be applied within the exhaust or silencing
chamber.
With the herein before described arrangement of reservoir above the engine no
circulating pump is required to cause the water to flow through the water jacket as
the said flow, or circulation will occur by convection. The wide branch connec-
tion D is arranged to carry the reservoir A and also to pass the water circulating
pipes.
"Sometimes we place lime or other suitable material in the exhaust chamber upon
trays or otherwise so disposed as to give a large absorbing surface in order to
absorb the noxious gases from the exhaust and so do away with any objectionable
smell.
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 :-
