' l ly invention relates tol automobiles, ,and

has for its ob'jectto provide a new-and improved device of this 'character in which the various ope'rationsvofy starting and'stoppin'g4 may be' effected with greater facility and without the use of complicated mechanism.

The invention consists in 'the construction described in the accompanying specification and set forth in the claims.

In the drawin s, Figure 1 is a side elevation of an automobie containing my invention. Fig. 2 v4is a similar view showing the `essential features of my invention.

in the drawings, a represents an automobile of conventional form having a metal frame b, as is usual and well known.

c represents the rear or driving wheelLand d the usual front Wheel. The rear or driving wheel d is mounted upon an axle g. This axle is secured to the upright -end of a drop axle-bar e, which is mounted in bearings 2 so I as to rock therein. c The rim h of the rear or ing-rod p to 'an operating-lever'n, fulcrurned at o in the frame of the machine.

Q represents a semicircular rack-bar having teeth which are en aged by a dog (not shown) mounted upon the operating-lever n. A pivoted operating-handle ris connectedto this dog, as will be readily understood.

Mounted in the frame of the machine adjacent the rear wheel is an operatingpulley Z,

grooved on its circumference. `'lhis pulley is'suitably connected. to a motor in any wellknown manner. The particular type of motor', however, forms no part of my invention,

and therefore has not been illustrated. The pulley Zhas also a reduced ortion l', the circumference of which is p ain. A rope or other flexible connection m connects the pulley lwith the rear Wheel, as shown. Mounted in the side bar of the frame is a brake-bar t',

having at the end adjacent the driving-wheel.

This will result in the tightening' of the rope or flexible con- 'wheel and the carriage will move forward. When the operating-lever is in its middle or neutral position, .the driving-wheel will be in the positionshowniin Fig. 1 and the flexible ment of the motor will not be transmitted to the driving-Wheel. quently remain standing. When it is desired to reverse the movement of the carriage and run backward, the operating-lever is 4pulled toward the rear of the carriage, as indicatedl in Fig. 2. This will swing. the axlewheel will move forward intoI engagement with the reduced portion rZ ofthe driving-pulley. The'. pulley, whichis constantly rotating in the direction indicated by the arrow in Fig. 2, will cause the driving-wheel to be turned in a reversed direction, asl indicated brake-bar and brake-shoe are ordinarily held by the latch in the position indicated in Fig. 1. When it lis desired to apply the .brake7 the o erating-lever is moved first to the posithe rear wheel forward into engagement with the brake-shoe. lt will be understood that. beforethe operating-lever can be moved farther to the rear, so as to vbring the driving- Wheel into engagementwith the pulley to v'drivethe carriage backward the-brake'must bereleased. This is accom lished by depressing the foot-lever w and re easin the latch fu,

It will also be understood that by the use of the drop-axles I am enabled to use Wheels of much larger diameter and provide a greater clearance between the carriage-body and the ground.

In an automobile, a frame, a drivingpulley, a driving-Wheel, means for moving the driving-Wheel away from the l'drivingpulley and for moving the driving-Wheel toward the vdriving-pulley into engagement therewith, and a s ring-pressed movable brake in the frame oeated in therpath of movement of the driving-Wheel.

2. In anautomobile!i yaframe, a drivingpulley, a driving-wheel, means for moving the driving-Wheel toward and away from the driving-pulley, a movable brake in the frame located in the path of movement of the wheel,

and means for holding the brake against movement.

3. In an automobile, a frame, a movable brake in the frame, means for holding the brake against movement7 a driving-Wheel movable into engagement with thel brake, means for releasing the brake, and means for returning the brake to normal position when released.y
