A Device to be Employed in connection with Gas-producers and Gas
Engines to Regulate the Motive Charge Drawn into the Engine.
I, MAURICE TAYLOR, of 16, Rue de la Grange Bateliére, Paris, in the Republic
of France, Engineer, do hereby declare the nature of my invention to be as
follows:
Four-phase "cycle" engines are recognised as being more advantageous than
other motors as they, amongst other advantages, are economical. of fuel, their
cost is small, and they occupy but a small space.
On the other hand gas producers generating poor gases, which operate below
atmospheric pressure, are in every respect superior to gas producers operating
under pressure, being more simple and safer, in addition to which they may be
cleansed whilst in operation and require no gasometer. Also, the composition of
the gases is uniform, whereby regularity in the operation of the engine is ensured.
Hitherto, it has been impossible to couple a four phase cycle gas engine with a
gas producer, from which the gases are drawn by the engine as the operating
piston employed in drawing in the gas has to draw in at the same time the air
necessary for the combustion of such gases. The composition of the explosive
mixture is a matter that requires careful attention, even where both the gas and
air are under a constant pressure. But where the pressure of the air only is constant
while the pressure of the gas varies, owing to the varying resistances it encounters
on its way to through and from the gas producer, the composition of the mixture
of air and gas constantly varies and prevents the proper operation of the engine.
The object of this invention is to provide means to overcome these objections
and means according to this invention are hereinafter described.
An apparatus according to this invention consists of a receiver or chamber
communicating through a pipe with the air suction valve of an engine or motor.
This chamber is provided with an air-inlet cock which can be opened more or
less by means of a lever controlled by a link and by a bellows or flexible bag,
one side of which is fixed, while the other is moveable. A pipe, leading from the
gas producer, opens into the said bellows, while another pipe connects the said
bellows with the gas inlet valve of the motor engine.
A counter weight is provided for the purpose of maintaining the bellows in an
elongated condition whilst only a minimum resistance is offered to the gas
proceeding from the gas producer, i.e., whilst the furnace and the purifying
chambers are at the maximum degree of cleanness.
The lever hereinbefore referred to is connected to a cock which turns with
slight friction so that it may follow the oscillating movements of the lever; the
size of the orifice or port of the said cock being such that, when the motor is
in normal operation, the bellows being elongated to the full extent and the cock
full on, the said cock still sufficiently contracts or throttles the air-inlet of the

page_text: chamber to reduce the pressure of the air, contained in such chamber, to a
degree somewhat below that of the pressure existing in the bellows, all this
taking place when the gas meets with a minimum resistance on its way from the
gas producer and purifying chambers.
The motor being thus in normal operation, and the bellows and the air-chamber
or reservoir having been properly regulated, air and gas in suitable proportions
are drawn in by the working piston, they being proportioned by their respective
inlets admitting them into the motor, by means, for instance, of cocks such as
are commonly used, the proportions, in the several positions of the piston, being
the same as would prevail were the piston to draw in compressed gas and air at
the atmospheric pressure, since poor" gases though below atmospheric pressure,
will, when drawn in, attain a pressure somewhat in excess of that of the air
contained in the reservoir. This will be the condition as long as the resistances
in the gas producer do not increase but when they do increase the pressure in the
gas passages and bellows will diminish, and the said bellows will collapse, its
moveable side coming near to its rigid side. During this movement of the
bellows, the cock, through the agency of the link and lever before described, will
close in proportion to the contraction of the bellows, so that the pressure in the air
chamber will be maintained below the pressure of the gases. The gases and air
will, therefore, in this case also, enter the engine cylinder in the same proportions,
and the operation of the engine will proceed without undergoing any alteration
by reason of any difference in the pressure of the gases drawn in.

A Device to be Employed in connection with Gas-producers and Gas
Engines to Regulate the Motive Charge Drawn into the Engine.
I, MAURICE TAYLOR, of 16, Rue de la Grange Bateliére, 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:-
Four-phase "cycle" engines are recognized as being more advantageous than
other motors as they, amongst other advantages, are economical of fuel, their
cost is small, and they occupy but a small space.
On the other hand gas producers generating poor gases which operate below
atmospheric pressure, are in every respect superior to gas producers operating
under pressure, being more simple and safer, in addition to which they may be
cleansed whilst in operation and require no gasometer. Also, the composition of
the gases is uniform, whereby regularity in the operation of the engine is ensured.
Hitherto, it has been impossible to couple a four phase cycle gas engine with a
gas producer, from which the gases are drawn by the engine as the operating
piston employed in drawing in the gas has to draw in at the same time the air
necessary for the combustion of such gases. The composition of the explosive
mixture is a matter that requires careful attention, even where both the gas and
air are under a constant pressure. But where the pressure of the air only is constant,
while the pressure of the gas varies, owing to the varying resistances it encounters

page_text: on its way to through and from the gas producer, the composition of the mixture
of air and gas constantly varies and prevents the proper operation of the engine.
The object of this invention is to provide means to overcome these objections
and means according to this invention are hereinafter described and illustrated
in vertical section in the accompanying drawing.
The apparatus consists of a receiver or chamber a communicating through a
pipe with the air suction valve of an engine or motor. This chamber a is
provided with an air-inlet cock c, which can be opened more or less by means of
a lever d controlled by a link e and by a bellows or flexible bag f, one side, g, of
which is fixed, while the other, h, is moveable. A pipe i, leading from the gas
producer, opens into the said bellows, while a pipe k connects the said bellows with
the gas inlet valve of the motor engine.
A counter-weight m is provided for the purpose of maintaining the bellows f in
an elongated condition whilst only a minimum resistance is offered to the gas
proceeding from the gas producer, .e. whilst the furnace and the purifying
chambers are at the maximum degree of cleanliness.
The cock turns with slight friction so that it may follow the oscillating
movements of the lever d; the size of the orifice or port of the said cock being
such that, when the motor is in normal operation,-the bellows being elongated
to the full extent and the cock c full on, the said cock still sufficiently contracts
or throttles the air-inlet of the chamber a to reduce the pressure of the air,
contained in such chamber, to a degree somewhat below that of the pressure
existing in the bellows f; all this taking place when the gas meets with a
minimum resistance on its way from the gas producer and purifying chambers.
The motor being thus in normal operation, and the bellows f and the air-
chamber or reservoir having been properly regulated, air and gas in suitable
proportions are drawn in by the working piston; they being proportioned by
their respective inlets admitting them into the motor, by means, for instance, of
cocks such as are commonly used, the proportions, in the several positions of
the piston, being the same as would prevail were the piston to draw in compressed
gas and air at the atmospheric pressure, since " poor" gases, though below
atmospheric pressure, will, when drawn in, attain a pressure somewhat in
excess of the air contained in the reservoir a. This will be the condition as long
as the resistances in the gas producer do not increase, but when they do increase,
the pressure in the gas passages, and bellows f, will diminish, and the said
bellows will collapse, its moveable side h coming nearer to its rigid side 9. During
this movement of the bellows, the cock c, through the agency of the link e, and
lever d, will close in proportion to the contraction of the bellows f, so that the
pressure in the air chamber a will be maintained below the pressure of the
gases. The gases and air will, therefore, in this case also, enter the engine
cylinder in the same proportions, and the operation of the engine will proceed
without undergoing any alteration by reason of any difference in the pressure of
the gases drawn in.
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
1 claim is:
1. For gas engines which draw in by their working pistons both gas producer
gases and the air required for their combustion, the employment of means whereby
the air is always at a pressure below that of the gas-producer gases, substantially
as hereinabove described and illustrated in the accompanying drawings.
2. For gas engines which draw in by their working pistons both gas producer
gases and the air required for their combustion; means for regulating the pressure
of the air, by means of variations in the pressure of the gases supplied by the gas
producer, substantially as hereinabove described and illustrated in the accom-
panying drawings.
3 For gas engines which draw in by their working piston both gas producer

page_text: gases and the air required for their combustion, the arrangement in the path of
the said gas-producer gases of a bellows or flexible bag the deformations whereof,
due to variations in the pressure of the said gas-producer gases, are utilised to
regulate the orifice admitting air into the air reservoir at low pressure, sub-
stantially as hereinabove described and illustrated in the acompanying drawings.
