I, CHARLES THERYC, Engineer, of Rue Nicolas, Marseilles, in the Republic
of France, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved motor device or compound generator and
motor.
In order that the following explanation may be rendered as clear as possible,
a construction of the improved apparatus will be described by way of example.
The compound generator and motor comprises: -
-
1) A compressing cylinder in which the combustion of the explosive mixture
is effected.
2) A reservoir surrounding the compressing cylinder and the driving cylinders,
and in which are stored under pressure the combustion gases as will be explained
further on.
3) Two driving cylinders in which the expansion and work of the gases is
effected.
The apparatus operates in the following manner :-
Under
The piston of the compressor cylinder draws through an automatically acting
valve carburetted air or explosive mixture which it subsequently compresses,
and the explosion of which is effected by an electric or other igniter.
the effect of the expansion and of the strong pressure of the gases subsequent
upon the explosion a differential valve which normally closes communication
between the compressor cylinder and the reservoir which are connected by a
pipe-opens automatically and admits the larger portion of the gases resulting
from the combustion into this reservoir.
The essential function of this valve is to prevent the explosive mixture during
its compression from entering this reservoir and to only admit the same after
its combustion. This valve comprises a pump body connected with the reservoir.
Part of this valve forms a syphon and contains oil, above which is a small
differential piston which actuates the valve by a lever arm held in position by
a balance spring. As the power of this spring is so adjusted as to be greater
than the pressure resulting from the previous compression of the explosive
mixture and smaller than the far more energetic pressure resulting from the
explosion: the valve will counteract and prevent the explosive mixture from
entering the reservoir at the moment of compression, and will only permit the
gases burnt in the explosion, to enter.

page_text: But in proportion as the reservoir fills and arrives at the desired pressure,
this pressure acts upon the liquid, and, consequently, upon the piston in the
syphon which then lifts the lever connected to it and the valve is thus set free,
and, being then only maintained upon its seat by the pressure in the reservoir
exerted through the conduit upon its upper face, it continues to act without
the aid of the lever, and, hence, it follows that the result aimed at is in all cases
attained.
The piston of the compressor cylinder under the impulse of the explosion,
subsequently moves outwards and inwards under the force acquired by the fly
wheels, causing those gases which have not been able to enter the reservoir, to
be expelled.
At the same time, an appropriate quantity of water is injected by a pump
or in any other way through an admission port, and this water becomes vaporised
in contact with the walls of the compressor cylinder while circulating in the
spiral conduit around said cylinder.
This circulation of the water may be prolonged, or be effected in the cylinder
bottom or cover and around the valves.
The steam thus generated passes into the chamber of the differential valve
wherein it is intimately mixed with the gases forced by the explosion and-
while becoming superheated in contact therewith-lowers the temperature of
the said gases to a normal degree.
The mixture resulting therefrom, passes through the conduit into the reservoir
where it is stored, ready to act and to expand alternately in the driving cylinders
by the action of suitable slide valves. It is introduced through a conduit or pipe
which terminates at the top of a second spiral conduit around the compressor
cylinder. This second spiral conduit is provided round the cylinder side by
side with the first-mentioned conduit, and terminates in a distributing chamber,
whence it passes to the slide valves through pipes. The gaseous mixture after
having acted upon the driving pistons passes out through the exhaust pipes.
All parts which are subject to radiation are preferably jacketted or covered
with non-heat-conducting material.
The generating or compressor cylinder may be placed above the driving
cylinder or it may of course, be arranged in any other suitable manner, and,
especially, on one of the sides, according to requirement, while however, sur-
rounding all cylinders with one and the same gas--and steam reservoir.
The economy of this construction lies in the fact that a large portion of the
heat may be utilized, which is set free by the explosion.
(1) By reducing more or less the richness of the explosive mixture, by the
addition of air, and by increasing in proportion, the compression of the mixture
in order to obtain a good combustion.
(2) By producing and superheating steam in a suitable quantity, the action
of which unites and combines with that of the gases, while at the same time
reducing the temperature of the walls and of the apparatus generally to a degree
compatible with the proper working of the constituent parts.

Improvements in or relating to Gas and like Engines and Motors.
I, CHARLES TIERYC, Engineer, of Rue Nicolas, Marseilles, in the Republic
of France, do hereby declare the nature of this invention and in what manner

page_text: by the following statement:-
This invention relates to an improved motor device or compound generator
and motor.
In order that the following explanation may be rendered as clear as possible
a construction of the improved apparatus is represented by way of example in
the accompanying drawing, in which:-
Figure 1 is a vertical section along the axis of the shafts.
Figure 2 is a broken section perpendicular to the axis of the shafts.
Figure 3 is a section in plan, on the line A-B of Figure 1.
Figure 4 is a section in plan on the line C-D of Figure 2.
Figure 5 is a sectional view of the differential valve.
-
The compound generator and motor comprises :-
1) A compressing cylinder a in which the combustion of the explosive mixture
is effected.
2) A reservoir d surrounding the compressing cylinder and the driving
cylinders, and in which are stored under pressure the combustion gases, as will
be explained further on.
3) Two driving cylinders b and c in which the expansion and work of the
gases is effected.
The apparatus operates in the following manner: —
The piston of the compressor cylinder a (Figure 1) draws through an auto-
matically acting valve 3 (Figure 1) carburetted air or explosive mixture which
it subsequently compresses, and the explosion of which is effected by an electric
or other igniter m (Figures 1 and 4). Under the effect of the expansion and
of the strong pressure of the gases subsequent upon the explosion, a differential
valve 5 (Figures 2 and 5)-which normally closes communication between the
compressor cylinder and the reservoir which are connected by a pipe /
(Figure 2) opens automatically and admits the larger portion of the gases
resulting from the combustion, into this reservoir. The essential function of
this valve is to prevent the explosive mixture during its compression from
entering this reservoir d and to only admit the same after its combustion. This
valve which is represented in section (Figure 5) comprises a bent tube 8, 7, 6
connected by. the extension 8 with the reservoir d (Figure 2). The part 7, 6 of
this valve forms a syphon and contains oil, above which is a small differential
piston 6 which actuates the valve 5 by a lever arm » held in position by a balance
spring. As the power of this spring is so adjusted as to be greater than the
pressure resulting from the previous compression of the explosive mixture and
smaller than the far more energetic pressure resulting from the explosion: the
valve 5 in its position indicated in the drawing will counteract and prevent the
explosive mixture from entering the reservoir at the moment of compression,
and will only permit the gases burnt in the explosion to enter.
As the reservoir d becomes charged with the products of combustion a back
pressure on the valve 5 would be created, and would tend to keep the valve
closed against further entry of products of combustion. The device described
above is provided to neutralize or counterbalance this back pressure since it is
evident that whatever pressure exists in the chamber & and tube acts not only
to keep the valve 5 against its seat, but also acts upon the piston 6, through the
interposed fluid, and thus tends to raise the lever and with it the valve 5 from
its seat, the pressure on both sides of the valve being thereby equalized, con-
sequently the spring on the end of the lever will always exert a constant
action upon the valve 5.
The piston of the compressor cylinder a under the impulse of the explosion,
subsequently moves outwards and inwards under the force acquired by the fly
wheels, causing those gases which have not been able to enter the reservoir, to
be expelled.

At the same time an appropriate quantity of water is injected by a pump or
in any other way through an admission port (Figure 2) and this water becomes
vapourised in contact with the walls of the compressor cylinder a while circu-
fating in the spiral conduit 2 around said cylinder.
This circulation of the water may be prolonged or be effected in the cylinder
bottom or cover and around the valves.
The steam thus generated, passes into the chamber of the differential valve 5,
wherein it is intimately mixed with the gases forced by the explosion and-while
becoming superheated in contact therewith-lowers the temperature of the said
gases to a normal degree."
The mixture resulting therefrom, passes through the conduit h (Figure 2) into
the reservoir where it is stored, ready to act and to expand alternately in the
driving cylinders and by the action of suitable slide valves e and f. It is
introduced through a conduit or pipe y which terminates at the top of a second
spiral conduit 1 around the compressor cylinder a. This second spiral conduit
is provided round the cylinder a side by side with the first mentioned conduit 2
and terminates in a distributing chamber 7 whence it passes to the slide valves e
and through pipes 9 and 10 (Figures 3 and 4). The gaseous mixture after
having acted upon the driving pistons b and c passes out through the exhaust
pipes 11 and 12.
All parts which are subject to radiation are preferably jacketted or covered
with non-heat-conducting material which are not represented in the drawings
nor are the safety valves and other accessory parts, in order to simplify the
drawings.
The generating cylinder or compressor which in the example of the drawing
is represented as placed above the driving cylinders may of course be arranged
in any other suitable manner, and especially, on one of the sides, according to
requirements, while however, surrounding all cylinders with one and the same
gas and steam-reservoir.
The economy of this construction lies in the fact that a large portion of the
heat may be utilized, which is set free by the explosion.
1) By reducing more or less the richness of the explosive mixture, by the
addition of air, and by increasing in proportion the compression of the mixture
in order to obtain a good combustion."
2) By producing and superheating steam in a suitable quantity, the action
of which unites and combines with that of the gases, while at the same time
reducing the temperature of the walls and of the apparatus generally to a degree
compatible with the proper working of the constituent parts.
Having now particulary 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. In an explosion engine of the compound generator and motor type,
storing, by the effect of the explosion itself, the larger portion of the gases of
combustion in a reservoir surrounding the apparatus, the said gases of combus-
tion prior to their acting as the driving power-superheating the steam produced
by the injection, around the generator, of a suitable quantity of water, thus
producing a mixture of gas and vapour ready to act and to expand upon the
driving pistons, these means and arrangements permitting of the utilization in
useful work of a large portion of the heat disengaged by the explosion, and of the
reduction of the temperature to a degree compatible with the efficient working
of the constituent parts, substantially as described.
2. A compound generator and motor comprising compressor and driving
cylinders, a reservoir around said cylinders, communications between said reservoir
and cylinders, and valves for opening or closing communication therein,
substantially as and for the purpose described.
3. In a compound generator and motor of the kind described a valve comprising

page_text: a syphon tube, a piston 6, connected to a spring controlled lever n carrying a
valve 5, substantially as described.
4. A compound generator and motor comprising a compressor cylinder a
driving cylinders b and c, and reservoir as d around said cylinders, spiral chambers
as 1 and 2 around the compressor cylinder, valved ports as 3, 4, 5, 9 and 10 and
communicating pipes as y and h substantially as set forth.
5. The complete compound motor and generator substantially as described
or illustrated in the accompanying drawings.
