Improvements in Motor or Horseless Road Carriages.
We CHARLES GAUTIER, and HAVIER WEHRLE, Engineers both of
135 Boulevard Haiessmann 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
ho particularly described and ascertained in and by the following statement :-
This invention for improvements in motor or horseloss road carriages has for its
main object to provide means whereby the motive power is transmitted to the
wheels of the carriage without the aid of chains or belts aud also to provide for
variation of speed of the carriage.
There is a considerable object in avoiding power transmission by chains or belts
in autocars as the latter are cumbersone and the former are noisy and neither of
them allow any inclination of the wheels.
In the accompanying sheet of illustrative drawings:-Fig. 1 is a sectional plan of
power transmitting mechanism arranged and constructed according to this invention
aud Fig. 2 is a detail view.
The cylinder shown in longitudinal section, is divided into two symmetrical
parts 1-1 in each of which a piston 2, 3 actuates by means of a double throw
orank 5, 6 a shaft 4. The shaft 4 carries a pinion 7 which is adapted to gear with
one or the other of two bevel spur wheels 12, 13 mounted to rotate on a socket 9
keyed to the shaft 8. The socket 9 is capable of longitudinal movement on the
shaft 8 and is pressed into the position shown by a spring z and is provided with
teeth or projections 10-11 which euter corresponding recesses in the bevel
wheels 12-13 thereby locking either of them to the shaft 8 as forward or backward
motion is desired. The movement of the shaft 8 is transferred to the shaft 14 by
means of gear wheels A. B. C. D. E. F. which are similarly keyed to the respective
shafts.
When it is desired to put the carriage in motion the engagement of the driving
shaft with the axle of the vehicle is effected by a special apparatus arranged as
follows.
A
On the shaft 14 is keyed piece 15 in two parts, between which a ring 24
(Fig. 2), having a rectangular section and divided into two segments jointed to the
axis 16, can open out. A rod g the two extremities of whichi threaded to the
right and to the left each entor into one of the segments of the ring, as shown
by (Fig. 2), carries rigidly secured to it a pinion 17 which is made to rotate by
sliding the rack 18 on the shaft 14 when the pinion rotates. the rod 9 which by
reason of its double thread forces the ring 24 to open or to close. In opening ít
comes into contact with the sleeve 19 aud carries it with it by friction.
The extension of the sleeve 19 carries a pinion 20 gearing with a toothed wheel 21
which finally transmits the power by means of a link joint 22 to the axle tree 23 of
the wheel.
The socket 9 permits of a change of speed by means of a single lever jointed on
the lugs of a ring fixed at a and by the intermediation of toothed wheels A B C
keyed on the shaft 14, and other wheels DEF keyed on the socket. Moving the
latter on the shaft ongagos successively by means of the lever, the wheels E. B. D. C.
thus obtaining change of speed.
The link joint has for its object to enable the usual inclination to be given to the
wheels. The car brake is applied on the sleeve 19.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The apparatus substantially as described with reference to the drawings and
in particular the novel application of the link joint enabling chains to be omitted
and inclination to be given to the wheels.
2. The system of alterution of direction of travel and speed and the system of
engagement the whole actuated by the same lever.
