Improved Mechanism for the Transmission of Motion, Chiefly
Designed for use in connection with Self-propelled Vehicles.
I, EMILE PROSPER LEON MORS, of 48 Rue du Theatre, l'aris, in the Republic of
France, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improved gearing or mechanism for the transmission
of motion by belting, chiefly designed for use in connection with self-propelled
vehicles.
My said invention comprises a special method of mounting pulleys, permitting
of obtaining, with transmission of motion by means of belting, forward and back-
ward motion and all variations in speed.
In order that my said invention inay he clearly understood, I have shown in
the accompanying drawings, in principle, by way of example only, my new
transmission-gear.
Figure 1 shows my improved gearing or mechanism in longitudinal section.
Figure 2 is a transverse section on the line 1-2, Figure 1.
Figure 3 shows the application of my gearing or mechanism to a self-propelled
vehicle.
In these figures, like letters of reference indicate corresponding parts.
My mechanism for the transmission of motion consists, in principle, as
follows:
On the transmission-shaft a is mounted a clutch or disconnecting device com-
prising a friction-cone or male clutch-section b, capable of being displaced along
the said shaft; this clutch-section serves to impart to the shaft a the rotary
motion which it receives from the hollow conical piece or female clutch-section c,
against which it is brought by the action of a spring d.
The female clutch-section c is driven by a special driving mechanism which
communicates rotary motion to it either in one direction or in the other and at
different degrees of speed.
This clutch-section c is mounted on a sleeve e which turns freely on the shaft a;
this sleeve e, on which is loosely mounted a pulley f, is provided at its free end
with a pulley g having internal teeth h.
The shaft a, moreover, bears a second sleeve i also free, on which is keyed a
pulley j, and which carries at its other end two pinions or planet-wheels k, geared
on the one hand with the internal teeth h of the pulley g, and on the other and
with a toothed pinion fixed on a pulley m which is capable of turning freely on
the sleeve i.
The pulley itself bears a brake-drum j, permitting of holding the stud-shafts
hearing the pinions or planet-wheels & stationary in the case of backward motion
of the mechanism.
To these two pairs of pulleys j, m and g, f, correspond two belts n, o, which
pass over two drums keyed on the driving-shaft, and the different positions of

page_text: which are controlled or regulated by two forks P, 9 operated by any suitable
means.
. As an example, I have shown diagrammatically in Figure 3, the application of
my improved gearing to the driving of a self-propelled vehicle.
The shaft r of the motor s bears two drums, t, t of different, diameters, over
which pass the two belts n o.
On the shaft a, which bears my improved transmission-gear, is provided a
differential gear u and to each of its ends is keyed a pulley or a toothed pinion,
these pulleys or pinions v transmitting their motion by means of belts or chains
to pulleys or pinions w rigidly secured to the driving-wheels .
The shaft a bears, in addition to the clutch, a brake y of any desired
construction.
A lever arrangement controlled either by a pedal or in any other suitable
manner, enables the brake y and the clutch-cone 6 to be operated successively, or
if desired, the latter can be operated directly by means of a special lever.
The pulley g can be closed at its open side by a plate or cover z, as shown in
Figure 1, so as to protect the gearing from dust; this arrangement, moreover,
enables the interior of this pulley to be filled with any suitable lubricant for the
purpose of reducing friction as much as possible.
Assuming the apparatus to be thrown out of gear and the belts placed as shown
in Figure 1, my apparatus operates as follows:-
In the case of motion in a backward direction, the brake-drum j is seized so
as to hold stationary the stud-shafts bearing the pinions k; the gear 7 turning in
the same direction as for forward motion, backward motion is imparted to the
crown or internal gear-wheel and consequently to the shaft a; the belt », pass-
ing over the loose pulley f, does not exert any action.
To obtain the slowest speed forwards, the belt is displaced progressively from
m to j; at the moment when the two pulleys m, j are driven at the same speed,
the shaft a receives this same speed; by reason of the slip, the said shaft, before
reaching this speed, passes through all the intermediate speeds between zero and
the speed of the belt.
When it is desired to work at a high speed, the belt is caused to pass from f to g.
In bringing the two belts successively back towards the right, the same phases
are repeated in inverse order.
It must be understood that my improved gearing or mechanism for the trans-
mission of motion can receive any other application and I reserve the right to
modify the form, dimensions and the accessory arrangements thereof according
to different cases.

Improved Mechanism for the Transmission of Motion, Chiefly
Designed for use in connection with Self-propelled Vehicles.
I, EMILE PROSPER LEON MORS, of 48 Rue du Theatre, 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:-
My invention relates to improved gearing
gearing or mechanism for the transmission

page_text: of motion by belting, chiefly designed for use in connection with self-propelled
vehicles.
My said invention comprises a special method of mounting pulleys for the
transmission of motion by means of belting, whereby forward and backward
motion and all variations in speed can be obtained.
In order that my said invention may be clearly understood, I have shown in
the drawing accompanying my Provisional Application, in principle, by way of
example only, my new transmission-gear.
Figure shows my improved gearing or mechanism in longitudinal section.
Figur 2 is a transverse section on the line 1-2, Figure 1.
Figure 3 shows the application of my gearing or mechanism to a self-propelled
vehicle.
In these figures, like letters of reference indicate corresponding parts.
My mechanism for the transmission of motion consists; in principle, as
follows:
On the transmission-shaft a is mounted a clutch or disconnecting device com-
prising a friction cone or male clutch-section b, capable of being displaced along
the said shaft; this clutch-section serves to impart to the shaft the rotary
motion which it receives from the hollow conical piece or female clutch-section
against which it is brought by the action of a spring d.
The female clutch-section c is driven by a special driving mechanism which
cominunicates rotary motion to it either in one direction or in the other and at
different degrees of speed.
This clutch-section c is mounted on a sleeve e which turns freely on the shaft z;
this sleeve c, on which is loosely mounted a pulley f, is provided at its free end
with a pulley g having internal teeth h.
The shaft a, moreover, bears a second sleeve i also free, on which is keyed a
pulley, and which carries at its other end two pinions or planet wheels k, geared
on the one hand with the internal teeth h of the pulley g and on the other hand
with a toothed pinion 7 fixed on a pulley m which is capable of turning freely en
the sleeve i.
The pulley itself bears a brake drum j, whereby the stud-shafts bearing the
pinions or planet-wheels k can be held stationary in the case of backward motion
of the mechanism being desired.
To these two pairs of pulleys j, m and g, f correspond two belts n, o, which
pass over two drums keyed on the driving-shaft, and the different positions of
which are controlled or regulated by two forks p, g operated by any suitable
means.
As an example, I have shown diagrammatically in Figure 3, the application of
my improved gearing to the driving of a self-propelled vehicle.
The shaft r of the motor s bears two drums t, of different, diameters, over
which pass the two belts n 0.
On the shaft a, which hears my improved transmission-gear, is provided a
differential gear u and to each of its ends is keyed a pulley or a toothed pinion v,
these pulleys or pinions v transmitting their motion by means of belts or chains
to pulleys or pinions to rigidly secured to the driving-wheels x.
The shaft bears, in addition to the clutch, a brake y of any desired
construction.
A lever arrangement controlled either by a pedal or in any other suitable
manner, enables the brake y and the clutch-cone b to be operated successively, or
if desired, the latter can be operated directly by means of a special lever.
The pulley 9 can be closed at its open side by a plate or cover z, as shown in
Figure 1, so as to protect the gearing from dust; this arrangement moreover
enables the interior of the pulley to be filled with any suitable lubricant for the
purpose of reducing friction as much as possible.
Assuming the apparatus to be thrown out of gear and the belts placed as shown
in Figure 1, my apparatus operates as follows:-

page_text: In the case of motion in a backward direction, the brake drum j is seized so
as to hold stationary the stud-shafts bearing the pinions &; the gear turning in
the same direction as for forward motion, backward motion is imparted to the
crown or internal gear-wheel and consequently to the shaft a; the belt o, pass-
ing over the loose pulley f, does not exert any action.
To obtain the slowest speed forwards, the belt n is displaced progressively from
m to j; at the moment when the two pulleys m, j are driven at the same speed,
the shaft a receives this same speed; by reason of the slip, the said shaft, before
reaching this speed, passes through all the intermediate speeds between zero and
the speed of the belt.
When it is desired to work at a high speed, the belt o is caused to pass from f to g.
In bringing the two belts successively back towards the right, the same phases
are repeated in inverse order.
It must be understood that my improved gearing or mechanism for the trans-
mission of motion can receive any other application and I reserve the right to
modify the form, dimensions and the accessory arrangements thereof according
to different cases.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed 1 declare that what I
claim is:
The improved mechanism for the transmission of motion by belting, chiefly
designed for use in connection with self-propelled vehicles, and comprising a
transmission-shaft on which is loosely mounted two sleeves one of which carries
at one end a clutch or disconnecting device and at its other end a pulley with
internal teeth, and is also provided with a loose pulley, the other sleeve being pro-
vided at one end with a driving pulley and at the other end with pinions or planet-
wheels geared on the one hand with the internally-toothed pulley and on the other
hand with a toothed pinion formed or fixed on another pulley loosely mounted on
this sleeve, these two groups of pulleys being driven by two belts which receive
their motion from the same driving-shaft, substantially as, and for the purpose
herein before described with reference to the drawings.
