page_text: The operation of the apparatus hereinbefore described is as follows.
The vaporiser C, Fig. I is heated by a lamp or fire until it is able to ignite the
mixture of air and petroleum or lighter oils or coal gas.
The piston A. Fig. 1 is shewn at the end of the cylinder B. Fig 1., and is close
to the vaporiser. The oil or gas is admitted, in certain proportions, to the vaporiser
by the action of levers which move the cocks or valves marked D. The levers are
actuated by cams on the crank or intermediate shafts.
The air to form the explosive mixture is admitted, under pressure and in certain
proportions, to the vaporiser by the cocks or valves marked E, E and G which
are opened by levers actuated by cams from the crank shaft or an intermediate
shaft. The cock or valve E', for the admission of air, is a supplementary cock or
valve, and is intended to be used only when it is found that cock E is inadequate to
supply a sufficient quantity of air such as would be needed when the engine was
required for heavy work.
The entrance or admission of oil or gas and air is almost simultaneous. The
valves or cocks D are opened first, admitting oil or gas; the valves or
cocks E and E', admitting air, are opened immediately after to force or press the
oil or gas forward into the vaporiser. An explosion takes place at once on the
entrance of oil and air into the vaporiser, as the action of the compressed air in
forcing the oil forward pulverizes the oil and renders its vaporisation instantaneous.
The piston is moved forward to the other end of the cylinder. The exhaust
valve is then opened, and, on the return of the piston to the end of the cylinder
and vaporiser, the products of combustion are driven out through the exhaust port L.
Fig. 1.
The piston, having made an outward and inward stroke and the crank-shaft one
revolution, the operation of admitting oil or gas and air at the proper moment and
in proper quantities is again performed, as herein previously explained. An explo
sion is thus obtained at each revolution and so on continuously. The oil or gas
may be further regulated by the piston valve G which is again actuated by levers
from the crank-shaft.
The air is heated in a receiver by a lamp or fire; or, by the exhaust pipe as
shewn at N. Fig. 2, so that on its admission with the oil to the vaporiser, an
explosion may be certain to take place at once. The oil is also heated before
admission to the vaporiser either by a lamp, or by the heat from the exhaust pipe
as shewn at O Fig. 2. The oil is also admitted under pressure.
The pressure of the air is obtained by an air pump, worked by the engine from
the crank shaft, or otherwise, pumping air into a receiver U, Fig. 4. The pressure
given to the oil may be by means of a pump, or by elevating the oil tank so as to
obtain pressure.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1st. The improved arrangement and construction of the vaporiser C and
cylinder B combined substantially as herein described and shewn on the accom-
panying drawings Fig. 1 and 3.
2nd. The improved arrangement whereby, in conjunction with cocks D, E, E and G,
oil or gas and air are sent direct into the vaporiser and cylinder, substantially as
herein described and shewn on the accompanying drawings, Fig. 1 and 3.
3rd. The arrangement, herein described, whereby an explosion takes place at
each revolution of the crank shaft and every double stroke of the piston.
