PROVISIONAL SPECIFICATION.
Self Starting Mechanism for Hydro Carbon Engines.
We HERBERT AKROYD STUART, of Bletchley Iron Works, Bletchley, in the
County of Buckinghamshire Mechanical Engineer and CHARLES RICHARD
BINNEY, of 5 Hackney Road, London, Consulting Engineer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to mechanism for starting hydro carbon engines but it is
more particularly adapted to start an engine as described in the Specification of
the Letters Patent No. 15994 and granted to Herbert Akroyd Stuart & Charles
Richard Binney and dated 8th October 1890 or with an engine having an automatic
igniting arrangement, or one using a heated vaporiser or cartridge.
We will describe the improved mechanism as applicable to the above referred to
engine.
Preferably a hand pump is employed to compress air in a receptacle or chamber,
suitably arranged about the engine-to the desired pressure-then supposing the
vaporiser to be heated ready for starting the engine, a supply of petroleum oil
is injected with the oil pump by hand into the vaporiser, the position of the
engine crank having a little lead or advance on its third or working stroke of the
cycle.
When the desired compression of the air and vapor is attained ignition takes
place by contact with the heated walls of the vaporiser; the piston is forced
forward by the explosion or expansion of the heated gases; on the return stroke
the products of combustion are ejected from the cylinder and the engine then works
on its usual cycle.
In some instances the supply of compressed air for starting the engine may be
produced by a pump actuated by the engine during motion as described in the
Letters Patent No. 15319, dated Nov. 24th 1886 and granted to Herbert Akroyd
Stuart and Charles Richard Binney.
Dated Oth day of December 1892.

COMPLETE SPECIFICATION.
Self Starting Mechanism for Hydro Carbon Engines.
HERBERT AKROYD STUART, Bletchley Iron Works, Bletchley in the County
of Buckinghamshire, Mechanical Engineer, and CHARLES RICHARD BINNEY
5 Hackney Road in the County of Middlesex Consulting Engineer, 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 :-
This invention relates to mechanism for starting hydro carbon engines, but it is
more particularly adapted to start an engine as described in the Specification of the
Letters Patent No. 15994 and granted to Herbert Akroyd Stuart, and Charles
Richard Binney and dated in the year 1890, or with an engine having an automatic
igniting arrangement, or one using a heated vapourizer or cartridge.
We will describe the improved mechanism as applicable to the above referred to
engine.
Preferably a hand pump is employed to compress air into a receptacle or
chamber, suitably arranged about the engine, to the desired pressure; then

page_text: supposing the vapourizer to be heated ready for starting the engine, a supply of
oil is injected with the oil pump by hand into the vapourizer; the position of
the engine crank having a little lead or advance on its third or working stroke
of the cycle.
When the desired compression of the air and vapour is attained, ignition takes
place by contact with the heated walls of the vaporiser, the piston is forced
forward by the explosion, or expansion of the heated gases. On the return stroke
the products of combustion are ejected from the cylinder, and the engine then
works on its usual cycle.
In some instances the supply of compressed air for starting the engine, may be
produced by a pump actuated by the engine during motion as described in the
Letters Patent No. 15,319, dated Nov. 24th 1886 and granted to Herbert Akroyd
Stuart, and Charles Richard Binney.
In order that our said invention may be more fully understood, annexed hereto
is a sheet of drawings wherein Fig. 1 is a longitudinal part section of the improved
mechanism; and Fig. 2 is end view of same, similar letters refer to similar parts in
all figures.
A is the cylinder. B is the piston or trunk suitably connected with the crank of
the engine by the rod C. D is the vaporiser or cartridge communicating with the
cylinder A.
In starting the engine, the hand pump E is actuated from the handle F so as to
accumulate or compress atmospheric air or other fluid into the receptacle G.
Preferably a check or other suitable valve I is conveniently arranged between the
said receptacle and the vaporiser, to prevent the explosive mixture communicating
with the receptacle G. A suitable gauge or indicator may be affixed to the
receptacle G so as to indicate the pressure contained therein.
To start the engine oil is injected from the oil pump or its equivalent through
the pipe H. into the vaporiser or cartridge D which has been previously heated;
oil vapour or gas is generated, and by opening the valve K the compressed
atmospheric air or other fluid from the receptacle G expands or escapes and mixes
with the vapour in the vaporiser or cartridge D. until an explosive mixture is
produced by which means the piston or trunk is propelled forward, producing the
revolution of the engine; the products of combustion are discharged on the return
stroke, and the engine subsequently follows on its usual cycle.
Having thus particularly described and ascertained the nature of our said inven-
tion we now declare that what we claim is :-
1. The construction and arrangement of the apparatus for compressing air to be
used substantially as set forth and for the purpose herein described.
2. The mode of admixture of this compressed air at the proper time, with oil
injected into the heated vaporiser by which an explosion is caused.
3. The combination of these arrangements with an oil engine in such a manner
as to start the engine easily and quickly substantially as set forth and described
herein.
Dated this 30th day of August 1893.
