Abstract: A pulley on an output shaft of an engine is coupled via a belt to a drive pulley which is mechanically coupled to the drive wheels of a vehicle. The tension of the belt is controllable by forward movement of a control lever from a neutral position; the control lever being arranged to shift the drive pulley relative to the output shaft pulley. The controlled variations in the tension of the belt caused by movement of the control lever produces a controlled degree of mechanical coupling between the output shaft pulley and the drive pulley to control the forward speed of the vehicle. A friction surface, provided on a circumferential periphery of the drive pulley, is capable, upon reverse movement of the control lever from the neutral position, of directly engaging with the output shaft pulley to cause reverse movement of the vehicle.

Abstract: An apparatus for dispensing a predetermined number of golf balls has a hopper for storing golf balls, a receptacle for retaining the predetermined number of golf balls in position for dispensing, and a structure for guiding and conveying the golf balls from the hopper to the receptacle. Such structure includes a passageway and a wheel having a resilient outer circumferential surface defined by a plurality of substantially radially extending bristles thereon. The receptacle has an openable and closable gate at one end thereof through which the predetermined number of golf balls therein are dispensed. Structure is also provided for rotating the wheel to fill the receptacle until the predetermined number of golf balls are filled therein after the gate is closed after discharge of the golf balls therefrom.
