PROVISIONAL SPECIFICATION.
Improvements in Hydro Carbon Engines.
JAMES ARTHUR DRAKE No. 3 Wellington Place Woodbridge Road Guildford
Surrey do hereby declare the nature of this invention to be as follows:-
This invention relates to liquid hydro carbon engines of the two or three cycle,
and comprises improvements in the arrangement of the vapouriser at the end of the
cylinder of vertical or horizontal engines, regulating the supply of air through the
vapouriser, placing the vapouriser inside the cylinder instead of outside, mode of
heating the vapouriser for starting using the exhaust pipe as a chimney to carry
off the products of combustion from the starting lamp by keeping the exhaust valve
open, regulating the heat of the vapouriser with water circulation &c.
The vapouriser is formed on the inside of the back cylinder cover, and is also a
part of the same and made smaller in diameter than the inside of the combustion
chamber of the cylinder, and fitted with a valve opening into the cylinder for the
admission of the air & vapour controlled by mechanism. The air is admitted
through the top cover and regulated by a valve to the bottom or over the top of
the vapouriser as required. The heating of the vapouriser for starting is effected
through a hole cast in the side of the combustion chamber opposite the exhaust
valve, a lamp is placed into this hole the flame of which passes round the vapouriser
inside the combustion chamber and through the exhaust valve to the atmosphere.
A groove
cast round the central portion of the vapouriser cover and connected
by an inlet and outlet pipe fitted with a stop cock to the cylinder jacket for
regulating the temperature of the vapouriser by a large or small supply of water.
At the bottom of the vapouriser inside the combustion chamber of the cylinder a
pipe is inserted for draining off any surplus oil that may accumulate at the bottom
of the vapouriser.

COMPLETE SPECIFICATION.
Improvements in Hydro Carbon Engines.
I, JAMES ARTHUR DRAKE 63 Woodbridge Road Guildford 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 liquid hydro carbon engines of the two or three cycle
and comprises improvements in the arrangement of the vaporiser at the end of the
cylinder of vertical or horizontal engines, regulating the supply of air through the
vaporiser, placing the vaporiser inside the cylinder instead of outside; mode of
heating the vaporiser for starting; using the exhaust pipe as a chimney to carry
off the products of combustion from the starting lamp by keeping the exhaust valve
open. Regulating the heat of the vaporiser with water circulation.
The vaporiser is formed on the inside of the back cylinder cover, and is also a
part of the same and made smaller in diameter than the inside of the combustion
chamber of the cylinder, fitted with a valve opening into the cylinder for the
admission of the air and vapour controlled by mechanism. The air is admitted
through the top cover and regulated by a valve to the bottom, or over the top of

page_text: the vaporiser as required. The heating of the vaporiser for starting is effected
through a hole cast in the side of the combustion chamber opposite the exhaust
valve, a lamp is placed into this hole, the flame of which passes round the vaporiser,
inside the combustion chamber-and through the exhaust valve to the atmosphere.
A groove is cast round the central portion of the vaporiser cover and connected by
an inlet and outlet pipe to the cylinder jacket fitted with a stop cock for regulating
the temperature of the vaporiser by a large or small supply of water.
bottom of the vaporiser inside the combustion chamber of the cylinder, a pipe is
inserted for draining off any surplus oil that may accumulate at the bottom of the
vaporiser.
Referring to the annexed drawings
:-
At the
Figure 1 sectional side elevation through a cylinder according to my invention.
Figure 2 sectional side elevation at right angles to that of Figure. 1.
Referring to Figures 1 & 2 a is the cylinder in which the piston b moves; the
vaporiser.c projects into the combustion chamber as shown & forms the cover of
the cylinder a.
d. is an aperture in which a lamp e is placed when it is desired to
start the engine. This aperture being normally closed by a suitable cover. fis
the tube for supplying the oil to the vaporiser. The required amount of air enters
by the apertures g in the tube or sheath h, the supply to the combustion chamber
being regulated by the valve i consisting of a sliding tube having apertures j,
corresponding with apertures in the tube or sheath h. This tube i may be
operated by the rod & lock nut m, so as to raise or lower the tube i & thus open or
close the apertures k & j. is a tube for draining off any surplus oil that may
collect in the vaporiser being closed by auy convenient arrangement such as a táp
or cock.
o is a water space or jacket running round the vaporiser c as shown &
having convenient supply and exit pipes p & g. is a small cock or tap
communicating with the water space o, for the purpose of allowing air to enter same
when it is desired to withdraw the water, from same by opening a tap or cock at a
lower level. s is the water space surrounding the cylinder a. Any well known
arrangement of igniting may be employed.

The working is as follows:-When it is desired to start the engine the lamp or
burner e is inserted in the aperture d & the vaporiser is thus heated the fumes
passing out through the exhaust port t-which is opened for this purpose.
When the vaporiser has been sufficiently heated the lamp or burner c is with-
drawn & the aperture d closed by a suitable cover or lid & the oil vapour & air
may then be ignited in the ordinary manner. u is the valve which. regulates the
admission of the mixed air & oil vapour to the combustion chamber v. The valve u
& exhaust valve w, are connected to and operated by the engine in the ordinary
manner.
12.
By this arrangement and construction of vaporiser the oil is not burnt when the
engine is at work owing to the circulating water keeping the vaporiser at the
desired temperature; and when starting a saving of time is effected as the vaporiser
can be readily heated to the desired temperature, before the oil is admitted; and
the smell which is caused by the imperfect vaporisation of oil when an engine is
started with a cold vaporiser is thus avoided.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
.
1
1. The combined construction & arrangement of the various parts substantially
as described and illustrated.
2. In oil engines of the class herein described, a vaporiser formed upon or
integral with the cylinder cover & projecting into the combustion chamber, showing
a valve communicating with the combustion chamber, & provided with a water
space or jacket, a tap or cock communicating with the upper part of said water
space & the outer air to facilitate the emptying of the water space a sheath
surrounding the oil tube projecting into the vaporiser at one end, the other having

page_text: apertures for the admission of air, a perforated tube sliding in said sheath operated
by a rod and nut or such convenient means; the sheath having perforations corre
sponding to those in the sliding tube aforesaid for the purpose of regulating the
supply of air, an aperture in the combustion chamber or cylinder, closed when
desired by a suitable cap or cover, for the purpose of inserting a lamp or burner -
for heating said vaporiser when desired, all in combination & substantially as
described and illustrated.
