The distributing device of the improved engine which forms the subject of the
said invention comprises a cam upon which moves a roller attached to a rod. This
rod is fixed at its lower part to a stirrup which moves the valve for admitting the
mixture to the discharged valve. Upon the said rod is provided the axis of a
pendulum which regulates the velocity of the engine. When the piston sucks, the
above mentioned cam presents to the roller a receding part, the rod slides and
bears upon the admission valve which allows the mixture to pass.
piston has arrived at the end of the stroke the roller passes upon a concentric
part of the cam until it encounters a nose-shaped part which raises it together
with the said rod and stirrup. The latter then moves the discharge valve, and
the products of the combustion which has taken place in the cylinder escape into
the atmosphere. As the engine continues to rotate the aforesaid roller passes
upon a concentric part of the cam and is then at rest.

I provide the aforesaid pendulum with a projection which strikes against an
arm when the said rod rises in order to actuate the discharge valve, and causes the
pendulum to oscillate more or less strongly. As the suction takes place imme-
diately after the discharge the roller descends into a recessed part of the cam,
the said rod and pendulum descend likewise, the former opening the valve for the
passage of the mixture and the latter the valve for the passage of the gas, if the
oscillation has not been too strong and the pendulum arrives in time.
the engine operates too quickly the thrust of the said arm against the projection
on the pendulum is stronger and the oscillation greater, and when the above-
mentioned rod descends again the pendulum not having had time to move back
towards the gas valve, passes to one side instead of opening this valve. Only air
is therefore introduced into the cylinder and no motive power is produced. A
spring which is put under more or less tension by means of an adjusting screw
enables the amplitude of the oscillations and consequently the velocity of the
engine to be regulated.

COMPLETE SPECIFICATION.
Improvements in Gas and other Motive-power Engines.
I, LEON LOBET, of 204 Rue Dailly, Brussels, in the Kingdom of Belgium,
Architect, 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 :-
My invention relates to gas and other motive-power engines.
My said invention is illustrated in the accompanying drawings in which,
Figure 1 is a side elevation of my improved engine and
Figure 2 is a vertical section of the same.
The distributing device of the improved engine which forms the subject of the
said invention comprises a cam A upon which moves a roller attached to a rod C.

page_text: This rod C is fixed at its lower part to a stirrup D which moves the valve E for
admitting the mixture to the discharge valve F. Upon the said rod C is provided
at G the axis of a pendulum H which regulates the velocity of the engine. When
the piston moves up the above mentioned cam A presents to the roller Ba
receding part A' the rod slides and bears upon the admission valve E which
allows the mixture to pass. When the piston has arrived at the end of the
stroke the roller B passes upon a concentric part of the cam A until it encounters
a nose-shaped part A2 which raises it together with the said rod C and stirrup D.
The latter then moves the discharge valve, and the products of the combustion
which has taken place in the cylinder escape into the atmosphere. As the engine
continues to rotate the aforesaid roller B passes upon a concentric part of the cam
and is then at rest.
I provide the aforesaid pendulum H with a projection I Figure 2 which strikes
against an arm J when the said rod C rises in order to actuate the discharge
valve, and causes the pendulum to oscillate more or less strongly. As the suction
takes place immediately after the discharge the roller descends into a recessed
part of the cam, the said rod C and pendulum descend likewise, the former opening
the valve for the passage of the mixture and the latter the valve K for the
passage of the gas, if the oscillation has not been too strong and the pendulum
arrives in time. If the engine operates too quickly the thrust of the said arm J
against the projection on the pendulum is stronger and the oscillation greater, and
when the above-mentioned rod C descends again, the pendulum, not having had
time to move back towards the gas valve, passes to one side instead of opening
this valve. Only air is therefore introduced into the cylinder and no motive
power is produced. A spring L which is put under more or less tension by means
of an adjusting screw M enables the amplitude of the oscillations and consequently
the velocity of the engine to be regulated.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First. The improved gas or other motive power engine provided with a distri-
buting device consisting of a cam upon which moves a roller attached to a rod
which at its lower part forms a stirrup, which moves the inlet valves for the
mixing and also the outlet valves, the said rod being provided with a pendulum
for regulating the velocity of the engine all, as hereinbefore described and repre-
sented in the drawings.
Second. The general arrangement of the engine herein before described combined
with the distributing device, substantially as specified and as shown in the
accompanying drawings.
