PROVISIONAL SPECIFICATION.
Improvements in Motor or Horseless Carriages.
I, EMILE ROGER, Engineer, of 15 Rue des Halles, Paris, in the Republic of
France, do hereby declare the nature of this invention to be as follows:-
This invention for improvements in motor or horseless carriages, has for its
principal object to automatically stop the motor when the driver either designedly
or accidentally leaves his seat, and consists in a spring seat for the conductor
connected to a valve or switch controlling the supply of motive fluid to the motor
or the circuit of the igniting device of the gas motor in such manner that when
the weight of the conductor is on the seat the valve is opened or the circuit closed
and when the conductor is off his seat, the seat rises to close the valve or open
the circuit and that the conductor can independently control the motor.
In one arrangement of mechanism for carrying out this invention, the admission
valve is connected to a spring tending to open the same and can be closed by
means of a connection to the conductors seat that can also be retained in any
intermediate position.
This connection is also arranged to be operated on in a direction to close the
valve by means of a strong spring lever that is operated to leave the said connection
free by the weight of the conductor on the seat.
In another arrangement an electric contact closed by the weight of the
conductor is arranged in the circuit to the electric igniting device of the engine.
If desired both arrangements may be fitted to ensure greater safety.

Improvements in Motor or Horseless Carriages.
I, EMILE ROGER, Engineer, of 15 Rue des Halles, Paris, in the Republic of
France, 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:-
This invention for improvements in motor or horseless carriages, has for its
principal object to automatically stop the motor when the driver either
designedly or accidentally leaves his seat, and consists in a spring seat for the
conductor connected to a valve or switch controlling the supply of motive
fluid to the motor or the circuit of the igniting device of the gas motor in such
manner that when the weight of the conductor is on the seat the valve is opened
or the circuit closed and when the conductor is off his seat the seat rises to
close the valve or open the circuit and that the conductor can independently control
the motor.
In one arrangement of mechanism for carrying out this invention, the admission
valve is connected to a spring tending to open the same and can be closed by means

page_text: of a connection to the conductors seat that can also be retained in any intermediate
position. This connection is also arranged to be operated on in a direction to
cluse the valve by means of a strong spring lever that is operated to leave the
said connection free by the weight of the conductor on the seat.
In another arrangement an electric contact closed by the weight of the conductor
is arranged in the circuit to the electric igniting device of the engine.
If desired both arrangements may be fitted to ensure greater safety.
In the accompanying drawings:
Fig. 1 shows a mechanism by which the admission valve P, which admits the
working fluid into the engine, is closed on taking the position P when the driver
is no longer seated on the seat S, and in consequence the latter no longer rests on
the head A of the rod T jointed to the end of the lever formed by the two right-
angled arms L, F, oscillating about the shaft O on which is also fixed a lever I at
the extremity of which is a helical spring R acting in the contrary direction to the
weaker spring R
The bent arm F bears against a stud a fitted on the rod C terminating in a
manipulating knob B and sliding through a socket D in which a hole is bored
allowing a stop pin B' attached to a chain to pass through. The rod C is provided
underneath with notches which can engage or hook into other notches cut in the
opening through which this rod passes.
The parts being in the position indicated it may be seen that by drawing out
the knob B in the direction of the arrow, the valve P may be more or less closed
and the rod C fixed in the desired position by means of the stop pin B₁ passing
through the socket D and one of the holes o, of the rod. The quantity of the working
fluid passing into the cylinder may thus be diminished. The driver can in this
manner regulate the speed of the carriage.
But if it be supposed that the conductor falls from his soat then the first
spring R reacts on the lever l and turns the shaft O, the arm F of which forces
the pin a forward and moves the rod C in the direction of the arrow, when the
valve P will assume the position P, cutting off the passage of the working fluid
which in this case is explosive carburetted air. The return movement will take
place even if the pin B is engaged in the socket D, if the latter is not fixed to
the carriage but simply rests on the surface of the front board. It will be under-
stood that the notches at the bottom of the opening through which the rod C
passes and those effected at the bottom of this rod, are arranged in such manner
as to allow the movement of the rod C following the direction of the arrow under
the preponderant action of the spring R relieved of the weight of the driver.
In internal combustion engines where the gaseous mixture is exploded by an
electric spark a modified arrangement shown by Fig. 2 may be employed, in which
the seat weighed down by the driver maintains the continuity of the circuit
through the spring acting as a contact. On the contrary the circuit is broken
when the driver moves from the seat S, as the spring » rises and does not maintain
the contact necessary for the passage of the electric current.
The two methods which have just been specified may furthermore be both
applied at the same time to ensure greater safety when gas or petroleum motors
are in question. In the modified arrangement shown by Fig. 2, the circuit may
be also broken at the driver's will by the manipulation of the small screw knob b
which may make or break the contact by means of a spring r¹.
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:
1. In automobile carriages for roads actuated by gas or petroleum motors,
the arrangement shown by Fig. 1 arranged in such manner that the weight of
the conductor ceasing to act on a spring R, the latter moves, in the direction
of the arrow f, a rod C drawn in the opposite direction by another spring R'
of less strength, and closes the valve P which shuts off the supply of gas to

page_text: the cylinder, the mechanism when the driver is seated allowing of the regulation
or stoppage of the engine.
2. In automobile carriages for roads actuated by gas or petroleum motors,
the arrangement shown by Fig. 2 arranged in such manner that by the weight
of the driver, a spring r up to that time forming a contact for the passage of the
electric current, rises and cuts the circuit thus preveuting the production of
the spark which would inflame the explosive mixture, this same circuit may
furthermore be broken at the will of the conductor by means of the small knob b
and the spring r¹.
3. In automobile carriages for roads actuated by gas or petroleum motors, the
arrangements indicated in Figs. 1 and 2 both applied at the same time for greater
safety, on the same carriage in order to stop the movement of the motor as soon
as the driver leaves his usual position on the seat, and this without in any way
impeding the action of the parts which regulate the action of the engine or cause
its stoppage by the will and in the presence on his seat of the driver.
