1, GEORGES DUPONT, of 31, Rue Cavé-Levallois, Perret (Seine), in the Republic
of France, Director of La Société Continentale d'Automobile do hereby declare the.
nature of this invention to be as follows:-
The present invention relates to an improved carburetting apparatus which
enables a perfect carburization of air or any suitable gas to be obtained mechani-
cally.
The invention also enables the carburetting substance to be automatically
admitted into the carburetter, proportionately to the speed of the motor and
the constant level in the carburettor to be dispensed with; it also enables the
substance in the reservoir, always of the same density and richness, to be used
to the last drop.
The carburettor comprises a cylinder or casing divided into two compartments
by a wall or partition, one of these compartments contains the mechanism for
regulating the admission of the substance into the carburizing chamber, which
latter chamber forms the other compartment.
The carburizing chamber is placed in communication with the reservoir con-
taining the carburetting substance, situated above the cylinder by means of a
pipe which is provided with a regulating valve or cock.
The regulation of the supply of the carburetting substance to the carburizing
chamber is effected by a centrifugal governor arranged in the first mentioned com-
partment and mounted on a shaft which passes through the cylinder. This
governor communicates an oscillatory movement to a connecting rod, through a
lever, which rod is connected to the plug of the cock or valve for the admission
of the carburetting substance into the carburizing chamber. In this chamber
the carburization of the air is effected by the energetic mixing of this air and
of the substance introduced therein, by means of two or more wings or vanes fixed
to, the axis of the governor.
The shaft of the governor upon which the said wings or vanes are fixed is
actuated by a pulley, which is suitably operated from the motor.
During the period of suction of the motor, the external air enters the carburizing
chamber by an opening in the casing thereof; this air is agitated by the wings
or vanes and becomes carburetted by mixing with the carburetting substance
entering the inlet tube, in larger or smaller quantities, according to the speed
of the motor, since the latter controls the rotation of the axis of the governor,
and consequently the opening of the feed cock or valve.
The carburetted air, on its exit from the carburizing chamber, enters a second
cylinder, where the gaseous mixture is properly proportioned by placing the said
cylinder in communication with the outside air by means of a tube in which
is arranged a cock for enabling the admission of air to be regulated.
The said cylinder is further provided with a valve which permits of the regula-
tion of the quantity of carburretted mixture admitted to the motor, and therefore
حيم

page_text: regulation of the speed of the said motor. The gaseous mixture is conveyed to
the motor by the tube, after passing through the openings in the regulating
valve.
After the carburettor has been in operation for some time, drops of the car-
buretting substance will probably accumulate in the lower part of the carburetting
chamber and prevent the proper working of the carburettor.
To obviate this inconvenience, the carburettor may be partly surrounded by a
casing, in which the deposit of the substance may accumulate, by dropping through
an aperture arranged for this purpose in the wall of the carburetting chamber.
In this case, the air enters the casing by an opening, arranged in the upper
part thereof, and a partition, conveniently arranged, compels this air to pass
around the carburettor and to take up the substance accumulated in the lower part
of the said casing, before entering the carburetting chamber; thus utilizing the
excess of the carburetting substance.
I do not desire to limit myself to the precise details of construction herein before
described as such details of construction may be varied according to circumstances
and if desired I may dispense with the centrifugal motion.
Moreover it is evident that if found desirable, the external air may be heated
in any suitable manner during its passage into the carburettor, as is done in
.certain carburetting apparatus.

Improvements in Carburetting Apparatus.
I, GEORGES DUPONT, of 31, Rue Cavé Levallois, Perret (Seine), in the Republic
of France, Director of La Société Continentale d' Automobile, 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:-
The present invention relates to an improved carburetting apparatus which
enables a perfect carburization of air or any suitable gas to be obtained mechani-
cally.
The invention also enables the carburetting substance to be automatically
admitted into the carburettor, proportionately to the speed of the motor, and
the constant level in the carburettor to be dispensed with; it also enables the
substance in the reservoir always of the same density and richness to be used
to the last drop.
This invention is illustrated in the accompanying drawing in which:
Figure 1 is a longitudinal diagrammatic section of the carburettor :
Figure 2 is a transverse section on line 2-2 of Figure 1 and
Figure 3 is a section on line 3-3 of Figure 2.
The carburettor comprises a cylinder or casing A, divided into two compart-
ments a and C by a wall or partition I; one of these compartments, viz; a, con-
tains the mechanism for regulating the admission of the substance into the
carburizing chamber C, which latter chamber forms the other compartment.
The carburizing chamber C is placed in communication with the reservoir
containing the carburetting substance, situated above the cylinder A, by means
of a pipe H, which is provided with a regulating valve or cock E.
The regulation of the supply of the carburetting substance, to the carburizing

chamber C is effected by a centrifugal governor R, arranged in the first mentioned
compartment a and mounted on a shaft r which passes through the cylinder A.
This governor communicates an oscillatory movement to a connecting rod F,
through a lever D; said rod F being connected to the plug of the cock or valve E
for the admission of the carburetting substance into the carburizing chamber C.
In this chamber C the carburization of the air is effected by the energetic mixing
of this air and of the substance introduced therein, by means of two or more wings
or vanes M fixed to the axis r of the governor R.
The shaft of the governor R upon which the said wings or vanes M are fixed
is actuated by a pulley G, which is suitably operated from the motor.
'
During the period of suction of the motor, the external air enters the carburizing
chamber C by an opening in the casing J thereof; this air is agitated by the wings
or vanes M, and becomes carburetted, by mixing with the carburetting substance
entering the inlet pipe H in larger or smaller quantities, according to the speed
of the motor, since the latter controls the rotation of the axis r, of the governor
and consequently the opening of the feed cock or valve E.
The carburetted air, on its exit from the carburizing chamber C, enters a second
cylinder L, where the gaseous mixture is properly proportioned by placing the said
cylinder L in communication with the outside air, by means of a tube 0; in which
is arranged a cock o for enabling the admission of air, for the purpose of this
rectification, to be regulated.
The said cylinder L is further provided with a valve cock K which permits
of the regulating of the quantity of carburetted mixture admitted to the motor,
and therefore the regulation of the speed of the said motor. The gaseous mixture
is conveyed to the motor by the tube U, after passing through the openings c and k
in the regulating valve K.
After the carburettor has been in operation for some time, drops of the sub-
stance will probably accumulate in the lower part of the carburetting chamber and
prevent the proper working of the carburettor.
a
To obviate this inconvenience the carburettor may be partly surrounded by
casing T, in which the deposit of the substance may accumulate, by dropping
through an aperture y arranged for this purpose in the wall of the carburetting
chamber C.
In this case, the air enters the casing T by an opening S, arranged in the
upper part thereof and a partitions, conveniently arranged, compels this air to
pass around the carburettor and to take up the substance accumulated in the
lower part of the said casing, before entering the carburetting chamber C by
the opening J; thus utilizing the excess of the carburetting substance.
I do not desire to limit myself to the precise details of construction herein before
described as such details of construction may be varied according to circumstances
and if desired I may dispense with the centrifugal regulator, indeed in cases where
it is desired to operate the tap E by hand, the regulator becomes useless.
Moreover it is evident that if found desirable the external air may be heated
as is done in
in any suitable manner during its passage into the carburettor
certain carburetting apparatus.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is
1. A carburettor comprising a mixing chamber (C) in which the substance
such as air or gas, to be carburetted is introduced automatically these elements
being mixed in the said chamber (C) by means of wings (M) mounted on an
axis (r), to which a rotary motion is given, as described above with reference to
the accompanying drawing.
2. In combination with the carburettor, as described in Claim 1, a casing (T)
intended to receive the excess substance which would accumulate in the mixing
chamber (C), the said casing being arranged in such a manner as to cause the

page_text: excess of substance to be sucked up by the air conveyed into the carburettor, as
above.described with reference to the accompanying drawing.
3. In a carburettor as described in Claims 1 and 2 and analogous carburettors,
a system of regulating the admission of the substance into the carburization
chamber (C), which consists of a centrifugal governor (R) mounted on a shaft (1),
set into motion by the motor; the said governor controlling the plug of the sub-
stance supply cock (E) by levers (D,. F), as described above with reference to the
accompanying drawing.
4. The carburettor substantially as above described with reference to the accom-
panying drawing.
