PROVISIONAL SPECIFICATION.
Improvements in Engines Worked by the Heavier Hydrocarbons.
JOHN HENRY KNIGHT of Barfield Farnham in the County of Surrey,
Engineer and Landowner do hereby declare the nature of this invention to be as
follows:-
In Patent 2783 of A.D. 1887 which was granted to me for a similar purpose
there is shewn a vaporiser for hydrocarbon or oil engines. My improvement
consists in obtaining greater efficiency and at the same time simplifying the con-
struction, and consists in making the vaporiser in one casting of either iron, steel,
copper, brass, or any suitable metal, and bolt such casting on to the end of the
cylinder. The annular space surrounding the combustion chamber, and between
the inner and outer walls being cored out grids, corrugations cast therein reach
from the inner to the outer walls thus strengthening the casting and adding to the
heating surface for warming the air and vaporising the oil.
The oil and air pass around the combustion space of the cylinder and its after.
end before entering the cylinder.
The after end of the vaporiser is closed with a door or cover which can be
removed for cleaning out the interior of the vaporiser.
The vaporiser may be either cylindrical, square or any other shape.
A flue or chimney may be made passing through the vaporiser to more readily
heat it for starting the engine, and regulating the heat of the vaporiser.
Another improvement is as follows:-
Occasionally oil is found to sweat through the vaporiser or the vaporiser is found
to leak at some joint, this causes a disagreeable smell; to avoid this I enclose the
vaporiser in a casing and take the air supply to the vaporiser or engine from this
casing, by this means the vapour is consumed and the disagreeable smell is
obviated.

COMPLETE SPECIFICATION.
Improvements in Engines Worked by the Heavier Hydrocarbons.
I JOHN HENRY KNIGHT of Barfield Farnham Surrey Engineer and Landowner
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 :-
In Patent 2783 of A.D. 1887 which was granted to me for a similar purpose,
there is shewn a vaporiser for hydrocarbon or oil engines, that is engines burning
in the cylinder the vapour of the heavy hydrocarbons, such as kerosine and other
lamp oils, commonly known as paraffin oils.
My improvement consists in obtaining greater efficiency and at the same time
simplifying the construction and consists in making the vaporiser in one casting
stamping or forging preferably a casting in any suitable metal iron, copper, or
brass &c. and to bolt such vaporiser onto the end of the cylinder.
The space surrounding the combustion chamber being cored out, some of the
grids or parts of them reach from the inner to the outer walls and strengthen the
casting, and as shewn in above named Patent add to the heating surface for
evaporating the oil.
The oil and air pass round the combustion space in an annular channel and
across its after end thus the air is heated and the oil vaporised before entering the
avlinder
