PROVISIONAL SPECIFICATION.
Improved Mechanism for Transmitting Motion, especially applicable
to Self-propelling Vehicles.
I, GEORGES DELANNOY, of 1, Rue Nationale, Beauvois, Nord, France,
Manufacturer, do hereby declare the nature of this invention to be as follows:
It is desirable that self-propelling vehicles be provided with means to enable the
speed at which they travel to be varied at will. Arrangements have been heretofore
employed for this purpose, but have all possessed serious drawbacks. Thus, the
speed of the motor itself has been varied; or gearing has been employed that has
always been difficult and intricate of operation; or friction-discs have been
employed which have not given a satisfactory result.
Now, the mechanism according to this invention for transmitting motion enables
the motion of the motor to be easily converted into any speed required on the road,
ranging from nil to the desired maximum speed.
The mechanism is based essentially on the use of an oscillating part which
through a connecting rod, receives the motion of the motor and transmits the
same through the medium of a block arranged to be adjusted by sliding in the
oscillating part and of a connecting rod, or of its equivalent, to any suitable
positive driving-mechanism mounted on the shaft that it is desired to drive.
An arrangement of mechanism according to this invention that is suitable for
rotating the driving-axle of a self-propelling vehicle comprises a shaft (hereinafter
referred to as the driving-shaft) that receives directly from the propelling motor a
continuous rotary motion has keyed upon it a crank that operates the oscillating
part by means of a connecting rod. The said oscillating part carries a block
which is capable of being adjusted in the said part in the direction of the length
thereof, and is connected by means of a rod to a positive driving-mechanism of any
suitable kind, which, at each stroke made in one direction, causes the shaft to be
driven to rotate to a certain extent.
When the sliding block is very near to the centre of oscillation of the said
oscillating part the amplitude of its movement is nil, or nearly nil; whereas this
amplitude is greatest when the sliding block is at the opposite end of the
oscillating part. It will be seen that it is possible, by bringing the sliding block,
by any suitable means, into intermediate positions of its course, to effect at will
greater or less angular displacements of the driving-arrangement and to obtain, as
a consequence, all possible speeds between zero and the maximum speed determined
by the arrangement of the parts. It will be understood, moreover, that according
to the amplitude of the angular displacement of the driving-arrangement, the speed
of the driving-shaft might be reduced by employing two, three, or even a greater
number of groups of oscillating parts, cranks, and driving-arrangements, the cranks
being keyed on the driving-shaft at angles suitably arranged for this purpose.
In an arrangement for the transmission of motion based on the same principle
and more particularly designed with a view to the transmission of the motion of
the motor to the driven shaft or to the driving axle, in a self-propelling vehicle
operated by a petroleum, gasoline, steam, or other motor, the oscillating part
receives its to-and-fro motion from the piston of the motor preferably directly;
but it may be otherwise and the oscillating part may, as in the arrangement
herein before described, receive its motion from a shaft that is given a circular
motion by the motor.

the oscillating part, in such a manner that the antifriction-roller can be made to
occupy all of the intermediate positions between those nearest to and farthest from
the centre of oscillation of the oscillating part.
In order to displace the sliding block and the antifriction-roller along the guide-
way or slot, I employ an arrangement comprising a screw on which is mounted a
pinion that gears into another pinion on a shaft that carries a toothed wheel in
engagement with another toothed wheel mounted on a shaft capable of being
rotated by the conductor or other person on the vehicle, the arrangement being
such that by imparting a rotary movement to the latter shaft by any suitable
means the antifriction-roller can be caused (both during working and otherwise) to
occupy all the positions desired in a guide groove or slot formed to receive it in
the arm of a piece that constitutes the principal part of a positive arrangement of
any suitable kind arranged to engage in one direction with the shaft to be driven
and to remain idle on this shaft in the other direction, communicating consequently
to this shaft the movement that is transmitted to the said principal part by means
of the sliding block and anti-friction roller. The oscillating part is or may be so
arranged with regard to the said principal part that the nearer the anti-friction
roller be brought, in the oscillating part to the centre of oscillation, the smaller
will be the angle of oscillation produced by the said oscillating part in the said
principal part and consequently, the less will be the angular movement imparted
to the shaft to be driven. If the antifriction-roller coincide exactly with the
centre of oscillation, the movement of the oscillating part will not have any action
on the said principal part and, consequently, the shaft to be driven will be allowed
to remain at rest.

Improved Mechanism for Transmitting Motion, especially applicable
to Self-propelling Vehicles.
I, GEORGES DELANNOY, of 1 Rue Nationale, Beauvois, Nord, France,
Manufacturer, 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 :-
It is desirable that self propelling vehicles be provided with means to enable the
speed at which they travel to be varied at will. Arrangements have been hitherto
employed for this purpose, but have all possessed serious drawbacks. Thus, the
speed of the motor itself has been varied; or gearing has been employed that has
always been difficult and intricate of operation; or friction-disks have been
employed which have not given a satisfactory result.
Now, the mechanism according to this invention for transmitting motion enables
.the motion of the motor to be easily converted into any speed required on the road,
ranging from nil to the desired maximum speed.
The mechanism is based essentially on the use of an oscillating part, which I will
call a “link” and which, through a connecting rod, receives the motion of the
motor and transmits the same through the medium of a block arranged to be
adjusted by sliding in the link and of a connecting rod or its equivalent, to any
suitable positive driving-mechanism mounted on the shaft that it is desired
to drive.

page_text: In the annexed two sheets of drawings
Fig. 1. is a diagram showing the application of the principle of my improved
mechanism in actuating the driving axle of a self-propelling vehicle.
Fig. 2. is a diagram showing the general arrangement of the improved mechanism.
as constructed under my invention.
Fig. 3. cn a larger scale, is a front view of the link shown in Fig. 2.
Fig. 4. is a vertical section on the line 4 -4 of Fig. 3.
Referring to Fig. 1, a designates a shaft which receives continuous rotary.
motion directly from any suitable motor not shown. The crank 6 upon the shaft a
imparts a to and fro motion to the link c by means of the connecting rod d. The
link c, which is pivotted at e, carries a block f which is capable of being adjusted.
in the direction of the length of the link and is connected by means of a rod g to w
positive driving mechanism of any suitable kind which, at each stroke of the rod g
in the direction of the arrow, causes a shaft i which is the driven shaft to rotate to
a certain extent.
When the block f occupies a position f¹ very near the centre of oscillation e
of the said link c, the amplitude of its movement is nil or nearly nil, whereas this
amplitude is greatest when the sliding block assumes the position f at the
opposite end of the link c. It will be seen that it is possible, by bringing the
sliding block by any suitable means into intermediate positions of its course,
to effect at will a greater or less angular displacement of the driving arrangement h
and to obtain, as a consequence, all possible speeds between zero and the maximum
speed determined by the arrangement of the parts. It will be understood, more-
over, that according to the amplitude of the angular displacement of the driving
arrangement h, the speed of the driving shaft a can be reduced by employing two,.
three or more group of links, cranks and driving arrangements, the cranks b being
keyed on the driving shaft a at angles suitably arranged for this purpose.
Referring to Figs. 2, 3 & 4, I have shown an arrangement for the transmission
of power based on the same principle and more particularly designed with a view
to the transmission of the motion of the motor to the driving shaft or to the
driving axle, in a self-propelling vehicle operated by a petroleum, gasoline, steam
or other motor.
In this arrangement, the link c receives its to and fro motion from the piston of
the motor, preferably directly; but it might be otherwise and the link may as in
the arrangement referred to in Fig. 1, receive its motion from a shaft that is given
a circular motion by the motor.
In the said Fig. 2, 3 & 4, I have used the same reference letters for designating
the same parts as those shown in Fig. 1. c is the link pivotted at e and to which
an oscillating movement is imparted by a connecting rod d, which is shown in
dotted lines and as broken off. An anti-friction roller o (Fig. 4) is mounted
loosely on an axis connected with the sliding block f which is capable of being
displaced in a guide-way or slot formed in the link c in such a manner that the
anti-friction roller o can be made to occupy, within the guide-way of the link, alt
the intermediate positions between the extreme positions o and o¹.
In order to displace the sliding block f and the anti-friction roller o along the
guide-way or slot of the link c, I employ the arrangement shown in Figs. 3 and 4.
Upon the screw p is mounted a pinion q that gears into another pinion 7 on a
shaft s.
The said shaft carries a tooth-wheel (not shown) in engagement with
On rotating the shaft u by
another tooth wheel t (Fig. 2) mounted on a shaft u.
O any suitable means, the conductor or other person on the vehicle can cause the
roller o (both during working and otherwise) to occupy all the positions desired in
a guide groove (Fig. 2) formed to receive it in the arm of a piece w that
constitutes the principal part of the positive arrangement of any suitable kind
arranged to engage in one direction with the shaft i to be driven and to remain idle
5 on said shaft in the other direction, communicating consequently to the shaft i the
movement that is transmitted from the linke to the piece w by means of the sliding
block and anti-friction roller o. The link c may oscillate from a to ¹ under the

page_text: action of the connecting rod d. If the roller o be supposed at the bottom of the
guide-way (in the position shown at o' Fig. 4) the link c will move the transmitting
mechanism from the position z to the position z¹. It is evident that the nearer
the anti-friction roller o be brought in the link c to the centre of oscillation e,
the smaller will be the angle of oscillation z', i, and consequently less will be the
angular movement imparted to the shaft i. If the anti-friction roller o coincide
exactly with the centre of oscillation e, the movement of the link c will not have any
action on the piece w and consequently the shaft i to be driven will be allowed to
remain at rest.
The link c may have connected to it a connecting rod g (one end of which only
is shown in Fig. 2.) which may be necessary in a self-propelling vehicle for instance
in actuating a pump or any other device.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. The herein before described construction of mechanism for transmitting
motion, especially applicable to self-propelling vehicles, substantially as set forth
and illustrated in Figs. 1, 2, 3 & 4 of the drawings.
