Improvements in Motors Worked by Petroleum or other Liquid
Hydrocarbon.
1, EMILE DELAHAYE, of 21 Boulevard Poissonneire, Paris, in the Republic of
France, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to motors working by petroleum or other liquid hydrocarbon
for propelling carriages, boats or other vehicles.
The motor made according to this mvention is formed with two parallel cylinders
which may be placed horizontally or vertically as desired and the pistons of the
cylinders are connected by connecting rods to cranks set at 180° apart or
diametrically opposite. A supply and an exhaust valve are provided for each
cylinder, each operating independently of the other and each being rendered easy
of access by a removeable plug provided for each valve.
The cylinders are provided with a jacket for the circulation of water for cooling
the said cylinders during work and a second jacket for heating the an to be
carburetted. The said cylinders are connected to brackets preferably of stamped
irou o cast steel for example carrying the bearings of the crank shaft. Two arms
which may be of forged iron and are provided with bearings for the shaft attach
the motor to the fame of the vehicle to which it is to be adapted. A casing
formed of a removeable thin metal plate surrounds and closes in the mechanism to
protect it from dust and it may form a reservoir for lubricating oil.
The air to be carburetted is first heated by passing through the jacket of the
cylinders and enters the upper part of the carburetter and after becoming
car buretted therein it leaves the carburette and passes to the cylinders by the
inlet valves theicto.
The hydrocarbon is automatically supplied to the carburetter by a float valve
adjusted so that when the level of the liquid in the carburetter tends to fall below
a predetermined height a fresh supply of oil enters by the valve. A constant
level of the oil and a means for regulating the proportion of gas and air forming
the explosive mixture are thus obtained.
The mixture then passes through the inlet valves and is compressed, ignited (for
example by an electric spark) and after having performed its work is expelled
through the exhaust valves which are raised from their seats by means of levers
operated by cans ou a hollow shaft which is rotated by a shaft and key so as to be
moveable transversely in either direction by a lever operated by the conductor and
provided with cams to determine the exact point at which the exhaust valves are
opened and closed. The same shaft also carries cams for effecting the starting of
the motor. These cams when they actuate the escape valves allow some of the
explosive mixture to escape without compressing it with the result that there is no
difficulty in starting the flywheel and that at the end of two or three turns a good
start is obtained.
The said shaft also carries a double cam with three stops for producing the
spark for lighting in each cylinder. The first step of the cam is for effecting the
lighting of the charge and for starting the motor the two others being for causing
ignition during the normal working of the motor but with different leads which
impart different speed and powder to the apparatus so that the conductor can, when

page_text: he desires, change the driving power of his motoi. The ignition may be produced
by an electric spark, or by a flame and an ignition tube or by any other suitable
meaus.
In an apparatus constructed according to my invention I secure maximum strength
with minimum weight and the parts can moreover be readily removed and replaced
in repairing or for other purpose.

Improvements in Motors Worked by Petroleum or other Liquid
Hydrocarbon.
I, EMILE DELAHAYE, of 21 Boulevard Poissonnière, Paris, in the Republic of
France, 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:-
My invention relates to motors working by petroleum or other hydrocarbon for
propelling caringes, boats, or other vehicles.
In the accompanying drawings a motor with its carbunetter constructed according
to my invention is shewn in elevation in Figure 1 and in plan in Figure 2;
Figure 3 shews the supply and exhaust valves in section, Figure 4 shews in
elevation part in section the means employed for operating the exhaust valves.
Figure 5 is a part plan thereof and Figure 6 shews the carburetter in section. The
motor made according to this invention is formed with two parallel cylinders which
may be placed horizontally or vertically as desired and the pistons of the cylinders
are connected by connecting rods to cranks set at 180° apart or diametrically
opposite. A supply valve a and an exhaust valve bare provided for each cylinder,
cach operating independently of the other aud each being rendered easy of access
by a removeable plug provided for each valve as shewn at in Figure 3.
"
The cylinders are provided with a Jacket c for the cuculation of water for
cooling the said cylinders during work and a second jacket d for heating the air
to be carburetted. The said cylinders are connected to brackets preferably of
stamped non o cast steel for for example carrying the bearings of the crank shaft.
Two arms e which may be of forged iron and are provided with bearings for the
shaft and blocks fattach the motor to the frame of the vehicle to which it is to be
adapted. A casing g formed of a removeable thin metal plate sumounds and
closes in the mechanism to protect it from dust and it may form a resei von for
lubricating oil
The air to be carburetted is first heated by passing through the jacket d of the
cylinder and enters the upper part of the carburetter haud after becoming
carburetted therein it leaves the carburetter by the exit and passes by the pipe a¹
and the inlet-valves a to the cylinders.
The hydrocarbon is automatically supplied to the carburetter by a float valve k
adjusted so that when the level of the liquid in the carburetter tends to fall below
a predetermined height a fresh supply of oil enteis by the valve; a constant level
of the oil and a meaus for regulating the proportion of gas and air fouming the
, explosive mixture are thus obtained.
The mixture passes through the inlet valves a as aforesaid and is compressed,
ignited (for example by an electric spark) and after having performed its work 18
expelled through the exhaust valves & which are raised from their seats by means
of levers L operated by cams q on a hollow shaft m (Figure 5) which 18 rotated by
a shaft n and key o so as to be moveable transversely in either direction by a lever p

page_text: (Figures 1 and 2) operated by the conductor. The cams y determine the exact
point at which the exhaust valves are opened and closed. The same shaft also
carries cams for effecting the starting of the motor. These cams when they
actuate the escape valves allow some of the explosive mixture to escape without
compressing it with the result that there is no difficulty in starting the flywheel V
(Figure 2) and that at the end of two or three turns a good start is obtained.
The said shaft also carries a double cam S with three steps for producing the
spark for lighting in each cylinder. The first step of the cam is for effecting the
lighting of the charge and for starting the motor, the two others being for causing
ignition during the normal working of the motor but with different leads which
impart different speed and power to the apparatus so that the conductor can, when
he desires, change the driving power of his motor. The ignition may be produced
by an electric spark, or by a flame and an ignition tube or by any other suitable
means,
In an apparatus constructed according to my invention I secure maximum
strength with minimum weight and the parts can moreover be readily removed and
replaced in repairing or for other purposes.
Having now particularly described and ascertained the nature of this inven--
tion and in what manner the same is to be performed I declare that what I
claim is
-
1. In motors of the kind specified setting the connecting rods at 180° apart so as
to secure a complete equilibrium between the moving parts and avoid vibrations
caused by the rotation of the said parts as described.
2. In motors of the kind specified the arrangement of the supply and exhaust
valves so as to enable them to be easily and readily inspected and cleaned and to
be separately removed if required substantially as described.
3. In motors of the hind specified a jacket d surrounding the cylinders for the
circulation of the air for carburation which becomes heated by contact with
the said cylinders and assists in effecting a further cooling already started by the
ci culation of water in another Jacket e substantially as herein before described with
reference to the drawings.
4. In motors of the kind specified brackets constituting frames or supports for
the motor shaft in combination with a removable metal casing enclosing the same
and preserving the mechanism from dust substantially as described.
5. The carburetter A with automatic regulating device substantially as herein-
before described and shewn in Figure 6.
6. The arrangement of a hollow or intermediate shaft combining rotary and
rectilinear movements so as to regulate thereby
(a) The escape of the gases
(b) Their compression and
(c) The ignition of the explosive mixture in any desired proportions-
substantially as herein before described.
7. The general construction, arrangement and combination of parts constituting
the improved hydrocarbon motor substantially as herein before described and.
illustrated in the accompanying drawings.
Dated this 19th day of June 1896.
