I, ERNEST EDOUARD COUTURIER, of 95, Boulevard Beaumarchais, Paris, in the
Republic of France, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to certain improvements in gas and petroleum motors.
One of the principal of these improvements consists in the employment, for
petroleum or gas motors, of two cylinders arranged end to end. Each of these
cylinders is double acting, that is to say the explosions take place alternately
upon each of the faces of the piston in each cylinder successively, in the same
manner as in a double acting steam engine, with cylinders arranged tandem
fashion operating one after the other, that is to say each cylinder furnishes its
two driving efforts successively during every alternate revolution only. The two
cylinders are thus alternating with regard one to the other.
This mounting tandem fashion of cylinders for petroleum land gas motors
is only rendered possible by the use of a special joint arranged between the two
cylinders, and this forms one of the characteristic features of the invention.
This joint is formed by a socket through which passes the rod common to the
two pistons. This socket is formed or provided with two discs or plates which
form the adjacent ends of the two cylinders. The rod common to both cylinders
which slides in the socket is provided at its middle point with a metal segment
or packing ring which forms a joint and ensures absolute tightness between the
two cylinders. The rod thus acts in the socket as a full piston in a cylinder, and
as the segment is always displaced to an equal degree at each stroke of the piston,
it is apparent that absolute tightness is ensured.
A single shaft driven by bevel pinions acts upon the distributing mechanism
of the two cylinders by means of cams acting laterally upon the exhaust valves.
The admission valves, as in all motors of this kind, are automatic in their action.
By the employment of the arrangement which has just been described, the
following advantages are obtained.
The cylinders being double acting and alternating it follows that the ordinary
cycle of four operations of an explosion motor are simultaneous, that is to say
each explosion is accompanied by a suction, a compression and a discharge. In
other words the explosion takes place at each extreme point of the stroke, which
gives two impulsions for each revolution, whilst in motors as hitherto constructed
only one impulsion per revolution has been obtained by employing two single
acting cylinders. As a consequence of obtaining two impulsions per revolution,
the bore of the cylinders may be reduced, the expansion increased beyond the
usual limits and the number of revolutions per minute in a three horse-power

The carburetter enables the quantity of liquid utilized at each suction to be

It consists essentially of a closed vessel within which two valves the seats of
which are oppositely arranged, are rigidly fixed upon the same stem in such a
manner that one is slightly open whilst the other is closed. The vessel, the
capacity of which may be varied as desired as it is made in two parts screwed
one within the other is provided with an aperture through which enters atmos-
pheric air under the influence of the suction produced in the lower pipe. The
air acts on the valve which opens to allow it to pass, the air then carrying with
it all the liquid contained in the vessel, because the upper valve is closed whilst
the lower valve is open.
As soon as the suction is at an end, the lower valve closes as does also the air
valve the upper valve on the contrary opens thereby allowing the liquid which
enters through the upper pipe, to fill the vessel.
The liquid carried along by the air whilst suction is taking place, falls upon
the small metal cone below the lower valve where the pulverisation is effected,
and where volatilisation is completed owing to the action of the air.
The governor acts on the valve spindle preventing the upper and lower valves
from rising, thus stopping the flow of the liquid and reducing the speed of the
motor.
The advantages of my carburetting apparatus are as follows:-
The liquid to be carburetted is isolated from the supply at each suction and it
is completely volatilised.
The carburetter producing, as is well known, a fall in the temperature of the
liquid, it is advantageous to cut off or isolate in uniform quantities the liquid
necessary at each suction.
With my carburetter the liquid is absolutely under control, the quantity having
once been regulated remains invariably the same for each suction, which is not
the case with other systems.
As the governor acts upon the supply of the liquid, it follows that when it
acts and cuts off this latter, atmospheric air only is sucked into the motor thereby
assisting to cool it.

I, ERNEST EDOUARD COUTURIER, of 95, Boulevard Beaumarchais, Paris, in the 50
Republic of France, Manufacturer, do hereby declare the nature of this invention

page_text: 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 certain improvements in gas and petroleum motors.
In order that my invention may be readily and clearly understood, I have repre-
sented, in the accompanying drawings, the different constituent parts of a
petroleum motor provided with the said improvements, the figures of the said
drawings being hereinafter referred to.
As shown in Figure 1, one of the principal of the aforesaid improvements con-
sists in the employment, for petroleum or gas motors, of two cylinders A and B
arranged end to end. Each of these cylinders is double acting, that is to say,
the ignition of the explosive mixture takes place alternately upon each of the
faces of the piston in each cylinder successively, in the same manner as in a double
acting steam-engine, with cylinders arranged tandem fashion operating one after
the other, that is to say, each. cylinder furnishes its two driving efforts succes-
sively during every alternate revolution only. The two cylinders are thus alter-
nating with regard one to the other.
This tandem arrangement of the cylinders of petroleum and gas motors is only
rendered possible by the use of a special joint or connection arranged between
the two cylinders, and this forms one of the characteristic features of the inven-
tion.
This joint or connection as represented in Figure 2 of the drawing, is formed
by a socket C through which passes the piston rod D common to the two
pistons E and F. This socket C is formed or provided with two discs or plates A¹
and B one of which A¹ forms the end of the cylinder A whilst the other B¹ forms
the end of the cylinder B. The piston rod I common to both cylinders which
slides in the socket C is provided at its middle point with a metal packing ring c
which forms a joint and ensures absolute tightness between the two cylinders.
The rod D thus acts in the socket C as a full piston in a cylinder and as the
packing ring is always displaced to an equal degree at each stroke of the piston,
it is apparent that absolute tightness is ensured.
A single shaft driven by bevel pinions acts upon the distributing mechanism
of the two cylinders by means of cams acting laterally upon the exhaust valves.
The admission valves, as in all motors of this kind, are automatic in their action.
By the employment of the arrangement which has just been described, the
following advantages are obtained.
The cylinders being double acting and alternating, it follows that the ordinary
cycle of four operations of an explosion motor are simultaneous, that is to say
each explosion is accompanied by a suction, a compression and a discharge. In
other words, the explosion takes place at each extreme point of the stroke, which
gives two impulsions for each revolution, whilst in motors as hitherto constructed
only one impulsion per revolution has been obtained by employing two single acting
cylinders. As a consequence of obtaining two impulsions per revolution, the
bore of the cylinders may be reduced the expansion increased beyond the usual
limits and the number of revolutions per minute in a three horse power motor
which is from 700 to 800 may be reduced to from 200 to 300. As a result of
this it is possible to dispense with water cooling devices, simple wings or
ribs G surrounding the cylinders being all that is necessary for cooling them.
As shown in Figure 3. The ignition is effected electrically by means of a
special porcelain candle H carrying the two poles I and J of a magnetic current.
These two poles I and J, which are normally in contact, are only separated
one from the other at the desired moment by a tappet upon the piston itself, which
thus causes the passage, always at the same moment, of the electric spark
required to produce the explosion. The height of the pole I may be varied by
means of a screw thread, thereby enabling the moment of separation to be
advanced or retarded at will, and consequently a variation of the ignition.
The carburetter, which is shown in Figure 4, enables the quantity of liquid
utilised at each suction to be proportioned regularly and in a constant manner.

page_text: It consists essentially of a closed vessel K within which two valves L and M,
the seats of which are oppositely arranged, are rigidly fixed upon the same stem N
in such a manner that one is slightly open whilst the other is closed. The
vessel K, the capacity of which may be varied as desired as it is made in two
parts screwed one within the other, is provided with an aperture through
which enters atmospheric air under the influence of the suction produced in the
pipe P. The air acts on the valve O' which opens to allow it to pass, the air then
carrying with it all the liquid contained in the vessel K because the valve L is
closed whilst the valve M is open.
As soon as the suction is at an end, the valve M closes as does also the valve O¹;
the valve L on the contrary opens thereby allowing the liquid which enters
through the pipe Q to fill the vessel K,
The liquid carried along by the air whilst suction is taking place, falls upon
the small metal cone where the pulverisation is effected, and where volatilisation
is completed owing to the action of the air. The governor acts at R, preventing
the valves L and M from rising, thus stopping the flow of the liquid and reducing
the speed of the motor.
The advantages of my carburetting apparatus are as follows:-
The liquid to be carburetted is isolated from the supply at each suction, and
it is completely volatilised.
The carburetter producing, as is well known, a fall in the temperature of the
liquid, it is advantageous to cut off or isolate in uniform quantities the liquid
necessary at each suction.
With my carburetter the liquid is absolutely under control, the quantity
having once been regulated remains invariably the same for each suction, which
is not the case with other systems.
As the governor acts upon the supply of the liquid, it follows that when it
acts and cuts off this latter, atmospheric air only is sucked into the motor thereby
assisting to cool it.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. A petroleum or gas motor having two cylinders arranged end to end, operating
alternately with regard one to the other, which comprises between the two
cylinders a joint formed by a socket or joint C rigidly connected with the oppo-
site ends of the cylinders and through which passes the rod 1 common to the
two cylinders carrying at its middle point a segment forming a joint within
the socket C and ensuring tightness between the two cylinders; the ignition of the
gaseous mixture being always effected at the same point by means of the two
poles of a magnetic current which are normally in contact and which are
separated in order to produce the electric spark by means of a tappet upon the
piston itself.
2. In combination with the petroleum motor above described and claimed, a
carburetter formed by a chamber of variable capacity provided with two
oppositely seated valves, rigidly fixed upon their stem in such a manner that one
is slightly open when the other is closed, the suction forcing the external air to
enter the chamber having variable capacity and to leave the same carrying with
it the whole of the hydrocarbon within such chamber as above specified.
