MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 788,852, dated May 2, 1905.

Application filed December 22, 1902. Serial Nv 136,203.

To all whom, it may concern:

Be it known that I, HENRY SnoHAUD, a citizen of the French Republic, residing at Gentilly, Seine, France, have invented certain new and useful Improvements in and Relating to Motor-Vehicles, of which the following is a specification.

This invention has for its object a device which permits of effecting by means of a single appliance changes of direction and velocity, throwing into and out of gear the braking, and also the regulation of motor-vehicles. The combination constituted by this device renders unnecessary all the individual 5 parts hitherto employed for operating the different mechanism, leaves the hands of the driver at liberty, and renders it possible for complete novices to drive motor-vehicles.

The invention is illustrated in the accompanying drawings, in which--- Figure 1 is a general view of a motor-vehicle provided with the device which forms the subject of this invention. Fig. 2 is a corresponding plan view, but with the motorcover removed. Fig. 3 is a vertical section on the axis of the device. Fig. 4 is a side elevation, upon a smaller scale, corresponding to Fig. 3 and also a section through this figure on the line A B C D. Fig. 5 is an elevation,

3 upon a larger scale, of the steering-pinion and rack. Fig. 6 is a plan view of the upper hand-whcelfot' Fig. 3. Fig. 7 is an elevation of the sector r, Fig. 3; and Fig. 8, a plan view 01 the same.

The device consists, Figs. 3 and 4, of a ground outer tube a, which is brazed at its lower portion to a cage or casingc and is carried by a pivot b. A tube d, arranged within the first, in which it rotates with easy friction, is rigidly connected at its lower portion with a pinion e and at its upper portion with a half hand-wheel f, carrying a disk 9, provided with an aperture to permit of thepassage of a tube it, provided at its lower extremity with a bearing surface for the spiral springy', the upper extremity of which bears against the disk 9. The tube 7 is fixed to a disk 7;, provided with pins Z, which pass through apertures formed in the half handwheel f and of which the lower extremities 5 enter cavities formed in a sleeve m exterior to the tube a and rigid with the lower half a of the hand-wheel. One of the arms of the hand-wheel member f is provided with an opening 0, Figs. 3 and 6, serving for the passage of a small bent lever 79, articulated upon this arm and furnished with a spring. This lever passes through a correspondingopening formed in the lower half 21. of the hand-wheel. The sleeve mmay engage with the teeth of the notched sector 1*, Figs. 3, 7, 8, mounted upon suitable rods s, Fig. 4, rising from the floor t of the vehicle and supporting the pivot Z). This sector is in two parts, arranged endwise in the same horizontal plane, between 5 which parts the tube a is able to move. It carries upon its upper edges notches formed upon a circumference described by elements of a circle corresponding to the lower circular section of the sleeve m. 7

The cage 0 supports a gear-wheel a, mounted upon a shaft w, connected by a universal joint 10 to a grooved shaft 11:, provided with a toothed wheel engaging with a circular rack of the steering-gear, Figs. 2, 4, and 5. A screw-threaded rod 1, Figs. 3 and 4, carrying a hand-wheel 2, passes with slight friction through the disk and engages in an elongated nut 3, formed at the extremity of a rod 4, terminatingiu a fork 5, articulated in a slotted arm 6, mounted at. the extremity of a shaft 7, connected by a universal joint 8 to a square shaft 9, arranged within a universal joint 10,

v in which it is adapted to slide, but which it carries with itin its movement oi. rotation in 5 a similar manner to the device of the shaft This shaft 9 is connected by a rod 10, Fig. l,

to the regulating parts 10. The cage 0 terminates in a fork 11, which connects the tube a by the intermediary of a rod 12 to the lever 9 13 of the speed-changing mechanism inclosed in the cage 26, Fig. 1, and the lever 46 of the brake 45.

The sector 7, Figs. 7 and 8, comprises a certain number 01 notches-ten, for examplewhich when the motor is in the explosion phase correspond the first notch I to the position brake applied and motor thrown out of gear-that is to say, running free; the sec- 1 ond II to brake released, the motor remaining out of gear; the third III, the fourth IV, fifth V, sixth VI to engagement with the low speed with a complete or progressive variation of advance for the ignition. enth VII, eighth VIII, ninth IX, and tenth X correspond to engagement with the high speed with variation for the advance of the ignition.

In explaining the operation we may assume the vehicle to be at a standstill and ready to start. The tube a occupies its rearmost position, its sleeve m being engaged in the notch I of the sector 7, Fig. 1, this notch corresponding to brake applied and motor out of gear. In

Y order to start the vehicle, the brake is released.

To effect this, the two hand-wheels f n are grasped by the hand and tightened in endeavoring to cause them to approach each other. The half hand-wheel n is raised. At the same time it releases the sleeve m. from the notch I. The hand-wheel and the tube a, are pressed in the direction indicated by the arrow A, Fig. 1, until the sleeve on is opposite the notch II. At this moment the hand-wheel n is abandoned and the sleeve m is drawn into the notch D D by the spring j, which acts by the intermediary of the pins Z. The tube a has oscillated around the pivots 7), and its lower fork 11 has exerted a thrust upon the rod 12, which, actuating the lever 46, has effected the release of the brake 45. By means of asimilar operation the sleeve m and the tube (a are pressed upon the notch III, which corresponds to the low speed. The oscillation of the tube a presses the rod 12 in the direction of the arrow 12. The lever 13 rocks around its pivot 14 and actuates the transmission-gear 26. If it is desired to steer at the same time, it is only necessary to rotate the hand-wheel f a in one direction or the other. This rotation causes that of the tube 6, which, by the intermediary of the toothed Wheels 6 and u, will act upon the shaft w, upon the toothed wheel y, and the circular rack 2, connected to the broken steering-levers, Fig. 2. If it is desired to act upon the regulating mechanism, the hand-wheel 2 is rotated in the proper direction, thus causing the slotted arm 6 to rise or descend. This arm actuates the shaft 9, which itself controls, by means of the rod 10, the regulating part 10. In the example cited the shaft 9 permits of acting upon the mechanism for regulating the advance of the ignition or the admission of the spirit, when the motor medium is a hydrocarbon, it is equally well adapted, if the motor is operated by steam, to open or close the admission-valve. If the motor is electric, it permits of establishing or interrupting the current. When it is desired to apply the brake,

the sleeve m is brought into the notch V by acting upon the tube in the reverse direction to that indicated by the arrow A. Traction is thus exerted on the rod 12 and the lever 46,

The sevand the brake is applied. There is thus obtained, by means of a continuous forward movement of the tube a, starting and proi gressive acceleration of velocity, and by the l reverse movement the velocity is progressively diminished and disengagement and stop page are effected. This arrangement is especially applicable to motor-vehicles, but is also adapted to stationary andotherengines in which it is desired to produce simultaneously changes of speed, of steering, and of direction of rotation.

The spring may be replaced by an elastic member interposed between the two handwheels f and n. The bent bolt or lever 99 serves to maintain the hand-wheel nraised when in certain cases it is not desired to engage the sleeve m in the notches of the sector '2'.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, what I claim is mounted to swing, means for transmittingthe swinging movement thereof, a tube arranged to turn in the swinging tube, means for transmitting the turning movement of said tube, a rod extended through the tube and movable longitudinally, and means for transmitting said longitudinal movement of the rod.
