Improvements in Petroleum Engines.
I JAMES FIELDS WEATHERLEY of the Borough of Saint Ives in the County
of Huntingdon Solicitor do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in petroleum engines whereby I obtain
two impulses at every revolution of crank shaft when running at full power
together with economy in working and prevention of leakage of noxious vapours.
The pistons cranks and connecting rods work in sealed chambers attached to the
cylinder castings the air contained in the said chambers being affected by the
movements of the pistons.
•
The pistons are connected to the cranks by rods in the usual way and are open
at the outer ends to the sealed chambers. The pistons are packed at both ends,
one end of each acts as an air pump and the other end compresses the charges and
receives the force of the explosions.
Another double walled chamber or vaporiser is attached to the cylinder castings
in a suitable position and is connected at one end by two separate passages or
portways having valves therein, with the two motor cylinders respectively, these
valves are worked by levers and cams or other suitable means from the crank
shaft.
The petroleum is contained in a tank placed in the bed of the engine and is kept
under pressure, the air for this purpose being supplied by a pump worked from the
main shaft by an eccentric in the ordinary way. The oil with a certain proportion
of air is forced from the tank through pipes to spraymakers attached to the
vaporiser and broken up into minute particles.
Air is first admitted to the motor cylinders through two separate passages or
portways respectively connecting them with the sealed chambers respectively, these
two last mentioned passages or portways being uncovered respectively by the
pistons on nearing the ends of their respective acting strokes and covered again
respectively shortly after their respective return strokes are commenced. The oil
and air which has been admitted to the vaporiser passes therefrom through the
passages or portways with valves therein, as the latter are respectively opened, to
the motor cylinders respectively and there mix with the air supplied from the
sealed chambers.
In this engine which may be vertical or otherwise the cylinders are respectively
closed at one end by a suitable cover to which is attached the exhaust valve for
each worked from the main shaft by cams and levers or eccentrics. The other
ends of the cylinders respectively open into casings forming the sealed chambers
within each of which is a crank working in suitable bearings in one or both walls
of the respective casings. The ends of the cylinders which are closed are those in
which the charges are received compressed ignited and expanded. The other ends.:
opening into the casings act as punips and supply air from valves in the casings as
before mentioned.
There are valves in the spraymakers worked from the shaft by cams and levers,
these valves are acted upon by the governors which may be centrifugal, or hit and...
miss pendulum, when the speed requires reducing.

being carried through and around between the outer and inner walls of the

Improvements in Petroleum Engines.
·I, James Fields Weatherley, Borough of St. Ives, County of Huntingdon
Solicitor, 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 improvements in petroleum engines whereby I obtain
two impulses at every revolution of the crank shaft when running at full power
together with economy in working & prevention of leakage of noxious vapour.
The piston cranks & connecting rods work in sealed chambers attached to the
cylinder castings the air contained in the said chambers being affected by the
movements of the pistons. The pistons are connected to the crank by rods in
the usual way & are open at the outer ends to the sealed chambers. The pistons
are parted at both ends one end of each acts as an air pump & the other end
compresses the charges & receives the force of the explosions. Another double
walled chamber or vaporiser is attached to the cylinder casings in a suitable
position & is connected at one end by two separate passage or portways having
valves therein with the two motor cylinders respectively these valves are worked
by levers & cams from the crank shaft.
The petroleum is contained in a tank placed in the bed of the engine & is kept
under pressure, the air for this purpose being supplied by a pump worked from the
main shaft by an eccentric in the ordinary way. The oil with a certain proportion
of air is forced from the tank through a pipe to spraymakers attached to the.
bottom of the vaporiser & broken up into minute particles.
Air is first admitted to the motor cylinder through two separate passages or
portways respectively connecting them with the sealed chambers respectively.
These two last mentioned passages or portways being uncovered respectively by
the pistons on nearing the ends of their respective acting strokes & covered!
again respectively shortly after their respective return strokes are respectively
commenced.
The oil & air which has been admitted to the vaporiser passes therefrom through
the passages or portways with valves therein on the latter are respectively opened
to the motor cylinders respectively & there mixes with the air. supplied from the
sealed chamber. In this engine which may be vertical or otherwise the cylinders
are, respectively closed at one end with a suitable cover in which is placed the
exhaust valve worked from the main shaft by cams & levers or eccentrics.
J
The other end of the cylinders respectively open into casings forming the sealed
chambers within each of which is a crank working in suitable bearings in one or
both walls of the respective casings. The ends of the cylinders which are closed
with covers are those in which the charges are received, compressed, ignited, &
expanded. The other ends opening into the casings act as pumps & supply air

reducing. The vaporiser is at first heated by burning a jet of oil & air from the
spraymaker or spraymakers or if preferred a separate lamp may be used. After
the engine has commenced running the vaporiser is kept sufficiently hot by the-
whole or a portion of the exhaust products as may be found necessary being carried
through & round between the outer & inner walls of the vaporiser before being
discharged into the atmosphere. The charges are fired by hot tubes or if preferred
by an electric spark.
Other
This engine can if necessary be made to run in either direction.
modifactions of petroleum motors may be constructed to work on the principles of
this invention as herein before set forth.
In order that my invention may be fully understood I will now refer to the
annexed drawings in which:
:-
Figure 1. is a sectional side elevation of my invention.
a & a' are two cylinders which are supplied with explosive oil vapour from the-
double vaporiser c that is the inuer vaporiser d supplies the cylinder a & the outer
one c supplies the cylinder a¹, e & e¹ are sealed chambers in which air is compressed
upon the forward stroke of the piston caused by the explosion of the oil vapour-
& air behind same.
This compressed air is admitted at or about the end of the forward stroke of the
piston for fat the points g & g' by means of the pipes & h¹ so as to clear the
products of combustion from the cylinders a & a¹ & at the same time providing a
certain amount of air which is compressed & mixed with the charge & fired as
usual by suitable means at k & k¹.
By this means two impulses are given to the crank shaft i. at each revolution of
same the products of combustion are caused to heat the vaporisers & pass to same
through the pipes & & thence to the outlets 1 & m. If desired I may dispense.
with one of the exhaust pipes such as k & allow the products of combustion to pass.
into the air direct from one of the cylinders thus using the exhaust from one.
cylinder only to heat the vaporiser by passing around same.
It will be seen that any well known & convenient form of valves & connections
may be employed to carry out the cycles described. The oil is carried in a tank in
the bed plate o which communicates with the vaporisers by means of the pipes p & p³.
for the oil & g & g' for the air. The air may be compressed in the tank by means
of the hand pump when starting the engine said pump being connected when,
required to the engine so as to be operated by same.
A suitable aperture closed by a door or cover may be provided on the sealed
chamber so that the cranks may be adjusted & lubricated when required.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is :-
1. The improved oil engine or motor all in combination substantially as
described.
2. In oil engines the improved vaporiser substantially as described & shown.
herein.
