Improvements in and relating to Gas and Petroleum Motors.
We, HENRI FRÉDÉRIC MONIN and GERASIME GUSTAVE PEROT, both of
69 Rue de Paris St. Denis Seine in the Republic of France, Manufacturers, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in gas and petroleum or other inflammable:
fluid motors.
The improvements more especially relate to the method of igniting the explosive
mixture and to the carburetor employed when hydrocarbons are used.
.
The said improvements are intended to facilitate the application of gas or
petroleum motors (especially petroleum motors) to vehicles and more particularly
to light vehicles such as tricycles for example.
The ignition chamber is located at the extremity of the cylinder near the rear.
end and communicating with the said cylinder by means of the orifices. We provide
an inlet valve for the admission of the air and gas which arrive through pipes cr.
passages and an escape valve which is actuated by an eccentric mounted upon
an intermediate shaft to which motion is transmitted in any suitable manner from
the motor shaft in the relation of two to one. This escape valve communicates.
with an orifice which opens either into the atmosphere or into any suitable
receptacle.
A spindle is arranged within the ignition chamber and upon such spindle a small
cam is provided. This spindle is actuated by the intermediate shaft by means of
an endless chain passing round wheels which are keyed.or fixed upon the said
spindle and upon the intermediate shaft respectively. Such actuation may however
be effected in any other suitable manner, the essential point being to impart rotary
movement to the cam.
Opposite this cam is arranged a small blade spring traversing a sheath or casing
which is suitably insulated from metallic contact; the cam comes into contact
with the blade on each revolution of the former.
The cam is electrically connected with one of the poles of a primary or secondary
battery or of any other source of electricity, whilst the insulated blade is connected
with the other pole. The sparks which are produced upon contact taking place
between the said cam and blade are sparks due to extra-current and not to
induction.
When the electric circuit is closed by the contact of the cam with the flexible
blade the current passes into a series of bobbins or solenoids of wires which are.
covered with some material offering resistance to the least leakage; these
bobbins are arranged one after another around a common core which is composed
of a large number of soft iron wires annealed in a special manner and which
serve to prevent any remanence or residual charge. Between each of the
bobbins or solenoids washers or partitions of some suitable insulating material
are arranged.
When the circuit is closed the current passes into the solenoids above referred
to and maguetises their common core, which, owing to its construction, is magnetised
and demagnetised very rapidly; when the circuit is broken, that is to say when
there is no longer contact between the cam and the blade, as a consequence of the
demagnetisation of the wires composing the common core of the solenoids, an
i

page_text: extra-current is produced which causes to pass between the cam and the blade a
spark of sufficient power to effect the ignition of gaseous mixtures even when these
latter are very poor.
These extra-current sparks ignite the explosive mixture drawn into the chamber
by the piston. As will be seen the sparks are produced in the body of the
mixture itself.
The ignited mixture passes from the chamber to the cylinder
through the openings.
When hydrocarbons are employed instead of gas, the carburetted air is caused
to enter through either one of the pipes or passages; all that is required to effect
this is a set of suitable cocks.
The carburetted air employed is produced by means of a device consisting of a
vessel or receptacle in which passes a pipe for the admission of the air, the lower
extremity of such pipe being closed and furnished with tubes of spiral form which
may be arranged in or at one or several layers or levels. The ends of these tubes
are open and they are in communication with the interior of the pipe; they are
immersed in the hydrocarbon which is introduced through an opening capable of
being hermetically closed.
Owing to the suction of the motor the air issuing from the tubes traverses the.
liquid mass whilst receiving a gyratory motion which effects a thorough stirring of
the said mass and ensures carburation taking place. The air after becoming
carburetted in this manner passes along the pipe which conducts it to the motor.
At the upper part of the receptacle a diaphragm is provided in order to prevent
any of the liquid from being carried away, whilst leaving the carburetted air
free to escape through the annular orifice which is left around the pipe.
It will of course be understood that both our method of effecting ignition
and the carburator itself are susceptible of application to all kinds of explosion
motors, and that we may also form their constituent parts of any appropriate
forms and dimensions, and likewise make use of any suitable substance for that
purpose.

We, HENRI FREDERIC MONIN and GERASIME GUSTAVE PEROT, both in
the Republic of France, do hereby declare the nature of this invention and in what
manner the same is to be perforined, to be particularly described and ascertained
in and by the following statement:-
This invention relates to improvements in gas and petroleum or other inflammable
fluid motors.
The improvements more especially relate to the method of igniting the explosive
mixture and to the carburetor employed when hydrocarbons are used.
The said improvements are intended to facilitate the application of gas or
petroleum motors (especially petroleum motors) to vehicles and more particularly
to light vehicles such as tricycles for example.
In order that the nature of these improvements may be readily understood
we will now describe the same with reference to the accompanying drawing in
which:
Figure 1 is a side elevation.of a motor of the four cycle type provided with our
improved igniting device.

page_text: Figure 2 is a section, drawn to a larger scale, taken on the line 2-2 of Fig.
and illustrating more particularly the method of ignition.
Figure 3 is another section taken upon the line 3-3 of Fig. 2..
Figure 4 is a vertical section through the carburetor, and
Figure 5 is a horizontal section taken on the line 5-5 of Fig. 4.
In the Figures 1, 2 and 3 A is an ignition chamber located at the extremity of
the cylinder B near the breech C and communicating with the said cylinder by
means of the orifices o, o¹; D is the inlet valve for the admission of the air and gas
which arrive through pipes or passages a and b respectively; E is the escape valve"
which is actuated by an excentric c mounted upon an intermediate shaft d to which
motion is transmitted in any suitable manner from the motor shaft F in the relation.
of two to one. This escape valve communicates with an orifice a which opens.
either into the atmosphere or into any suitable receptacle.
is a spindle arranged within the ignition chamber and upon such spindle a small
cam fis provided. This spindle is actanted by the intermediate shaft d by means.
of an endless chain G passing round wheels 9 and gl which are keyed or fixed upon.
the said spindle e and upon the intermediate shaft d respectively. Such actuation
may however be effected in any other suitable manner, the essential point being to..
impart rotary movement to the cam f.

Opposite this eam is arranged a small blade spring & traversing a sheath or
casing i which is suitably insulated from metallic contact; the cam f comes into
contact with the blade on each revolution of the former.
The cam is electrically connected with one of the poles of a primary or
secondary battery or of any other source of electricity, whilst the insulated
blade is connected with the other pole. The sparks which are produced upon.
contact taking place between the said cam and blade are sparks due to extra-
current and not to induction.
When the electric circuit is closed by the contact of the cam with the flexible:
blade the current passes into a series of bobbins or solenoids of wires which are
covered with some material offering resistance to the least leakage; these bobbins."
are arranged one after another around a common core which is composed of a.
large number of soft iron wires annealed in a special manner and which serve
to prevent any remanence or residual charge. Between each of the bobbins.
or solenoids washers or partitions of some suitable insulating material are
arranged.
When the circuit is closed the current passes into the solenoids above referred
to and magnetises their common core, which, owing to its construction, is magnetized.
and demagnetised very rapidly; when the circuit is broken, that is to say when
there is no longer contact between the cam fand the blade h, as a consequence of
the demagnetisation of the wires composing the common core of the solenoids, an
extra-current is produced which causes to pass between the cam f and the blade
a spark of sufficient power to effect the ignition of gaseous mixtures even when.
these latter are very poor.
These extra-current sparks ignite the explosive mixture drawn into the
chamber A by the piston. As will be seen the sparks are produced in the body
of the mixture itself. The ignited mixture passes from the chamber A to the-
cylinder B through the openings o, o¹.
When hydrocarbons are employed instead of gas, the carburetted air is caused to.
enter through either one of the pipes or passages a and 6; all that is required to
effect this is a set of suitable cocks.
The carburetted air employed is produced by meaus of a device represented in
Figs. 4 and 5 of the drawings.
Into a vessel or receptacle G passes a pipe H for the admission of the air, the
lower extremity of such pipe being closed and furnished with tubes j of spiral form
which may be arranged in or at one or several layers or levels. The ends of these
tubes are open and they are in communication with the interior of the pipe H ;.

page_text: they are immersed in the hydrocarbon which is introduced through an opening k
capable of being hermetically closed.
Owing to the suction of the motor the air issuing from the tubes j traverses the
liquid mass whilst receiving a gyratory motion which effects a thorough stirring of
the said mass and ensures carburation taking place. The air after becoming
carburetted in this manner passes along the pipe which conducts it to the
motor. At the upper part of the receptacle G a diaphragm I is provided in
order to prevent any of the liquid from being carried away, whilst leaving the
carburetted air free to, escape through the annular orifice which is left around
the pipe H.
It will of course be understood that both our method of effecting ignition
and the carburetor itself are capable of being applied to all kinds of explosion
motors, and that we may also form their constituent parts of any appropriate
forms and dimensions, and likewise make use of any suitable substance for that
purpose.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In gas or petroleum motors, the method of ignition by means of extra-current
sparks produced between a cam and an insulated flexible blade, all located in an
ignition chamber, the electric current being obtained from any suitable source and
passing, in order to produce this result, through a series of bobbins or solenoids
arranged side by side upon a single or common core formed from a large number of
annealed soft-iron wires, and separated by a partition of any appropriate insulating
material, all as above specified with reference to the drawings.
2. The arrangement of this igniting device in an ignition chamber, in combination
with a chain or other transmitting mechanism actuated from the motor shaft or
from an intermediate shaft, and with suction and escape valves arranged upon the
said chamber as above specified.
3. The special arrangement of the carburetor described with reference to
Figs. 4 and 5 of the drawing.
4. The improved gas or petroleum motor substantially as herein described with
reference to Figs. 1, 2 and 3 of the drawing.
