A New or Improved Mechanism for Transmitting Power in
Auto-cars or Horseless Carriages.
I, HIPPOLYTE LEPAPE of 23 Rue Montaigne Paris, France, Civil Engineer
do hereby declare the nature of this invention to be as follows:-
My invention has for its object a new or improved mechanism applied to auto-
cars for transmitting power by means of gearings, this transmission being effected
by toothed pinions revolving like satellites around the axle of driving wheels,
this satellite movement allowing the coupling and uncoupling of a friction
pulley transmitting the power from the motor to the driving wheels in the required
direction and at the necessary speed.
The gearing being so arranged as to press the friction pulley forcibly and
gradually against a friction disc acting as a fly-wheel actuated by the motor when
the auto-car is moving iu a forward direction.
In order that my invention may be more clearly understood reference is made to
the annexed drawing in which :-
Fig. 1 is an elevation of my gearing mechanism.
Fig. 2 is a plan view of the same.
In these figures the same letters of reference indicate corresponding parts.
My transmitting mechanism is supplied with a toothed wheel furnished with
either interior or exterior cogs or with a lantern wheel A held in any convenient
way to each of the driving wheels B of the auto-car, this lantern or other wheel A
being actuated by toothed pinions C keyed on the shaft D.
This shaft D is supplied with a differential motion in case the two driving
wheels should be actuated by the motor. The said shaft D is held by two bearings E
jointed according to Cardan's system, fixed on oscillating arms H secured on the
axle of the driving wheels A. Between the arms H the shaft D has a polygonal
section or is supplied with a long cotter or projection thus allowing the friction
pulley the hub of which has a similar section to be placed freely on the shaft
the object of this disposition being to unite intimately the shaft and the pulley
in the rotatory motion and moreover to allow the pulley to slide from left to right
without the rotation being interrupted.
In this way a transmitting mechanism capable of revolving around the axle of
driving wheels is obtained and consequently the distance between the centres of the
gearings of the driving wheels and the centres of the pinions keyed on the shaft of
the friction pulley is invariable and moreover the gearing is never uncoupled.
The friction may thus be coupled or uncoupled at will and the speed or direction
may be changed by displacing the friction relatively to the centre of the rotating
friction disc N of the motor.

Auto-cars or Horseless Carriages.
I, HIPPOLYTE LEPAPE of 23, Rue Montaigne, Paris, France Civil 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 :--
My invention has for its object a new or improved mechanism applied to
auto-cars for transmitting power by means of gearings, this transmission being
effected by toothed pinions revolving like satellites around the axle of driving
wheels this satellite movement allowing the coupling and uncoupling of a friction
pulley transmitting the power from the motor to the driving wheels in the required
direction and at the necessary speed.
The gearing being so arranged as to press the friction pulley forcibly anl
gradually against a friction disc acting as a fly-wheel actuated by the motor when
the auto-car is moving in a forward direction.
In order that my invention may be more clearly understood reference is made to
the annexed drawing in which :-
Fig. 1 is an elevation of my gearing mechanism.
Fig. 2 a plan view of the same.
Fig. 3 is an enlarged view of a section of the friction disc and friction
pulley and
Fig. 4 a bottom view on a large scale of the friction disc.
In all these figures the same letters of reference indicate corresponding parts.
My transmitting mechanism is supplied with a toothed-wheel furnished with
either interior or exterior cogs, or with a lantern wheel A held in any convenient
way to each of the driving wheels B of the auto-car, this lantern or other wheel A
being actuated by toothed pinions C keyed on the shaft D.
The shaft D is supplied with a differential motion in case the two driving wheels
should be actuated by the motor. The said shaft D is held by two bearings E
jointed according to Cardan's system fixed on oscillating arms H secured on the
axle L of the driving-wheels B. Between the arms H the shaft D has a polygonal
section or is supplied with a long cotter or projection thus allowing the friction
pulley M the bub of which has a similar section to be placed freely on the shaft
the object of this disposition being to unite intimately the shaft and the pulley M
in the direction of the rotatory movement and moreover to allow the pulley to
slide from left to right without the rotatory movement being interrupted.
In this way a transmitting mechanism capable of revolving around the axle of
driving wheels is obtained and consequently the distance between the centres of the
gearings of the driving-wheels and the centres of the pinions keyed on the shaft of
the friction pulley is invariable and moreover the gearing is never uncoupled.
The friction pulley may thus be coupled or uncoupled at will and the speed or
direction may be changed by displacing it by a fork P relatively to the centre of
the rotating friction disc N of the motor.
This movement must be preceded by a lowering of the shaft D carrying the
pulley, which lowering may be produced by any lever whatever.
It the shaft of the friction pulley is made to rise until the pulley is applied on
the fly-wheel or friction-disc N this shaft will begin to turn and consequently
the pinions C will rise in the lantern-wheels thus increasing the pressure between the
friction pulley and the fly-wheel or friction-dise until the starting of the driving
wheel has been effected, that is the pressure will be in proportion to the resistance

between the fly-wheel and the friction pulley.
This friction pulley M receives its movement from the fly-wheel N of the motor.
This fly-wheel has concentric circular grooves with angular sections in which the
friction-pulley M may engage, this friction pulley having an elastic band and being
of conical shape, thus allowing the necessary alteration of shape to fit exactly in
the said grooves, the angles of which are not all like one another.
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 auto-cars or horseless carriages a transmission by friction comprising a
motive fly-wheel grooved or otherwise, actioning at will a friction pulley conical.
or otherwise turning with it a polygonal shaft over which it can slide lengthwise.
thus obtaining according to the position relatively to the centre of the fly-wheel.
different changes of rapidity and direction.
2. The transmission by gearing to the driving wheels by means of a shaft.
mounted on two brackets oscillating around the axle of driving wheels, this shaft
having at its extremeties a pinion gearing with a lantern wheel mounted on the
driving wheel this disposition preventing all ungearing of the pinion and its wheel
while permitting the oscillation of the shaft and consequently the coupling and
uncoupling.
3. The oscillating shaft allowing the coupling of the friction pulley mounted in:
said shaft with the motive fly-wheel and moreover the gearing of pinions in lantern-
wheels taking place in the required direction to permit the pinion from the first
movement to increase the pressure to such a degree as to prevent all sliding between.
the friction-pulley and its motive fly-wheel.
