DEFINITION

Classification: 476/4

Electric or magnetic control:

(under subclass 1) Subject matter wherein said means to change the rotational velocity are actuated by electric or magnetic energy. [figure] [caption] A continuously variable transmission in which power is transferred from an input shaft through gearing to an idler cone, and from the idler cone through gearing to an output shaft. The transmission ratio is a function of the ratio of output power required to the input torque as determined by a torque sensing means. When power from prime mover is applied

through system sensor (13) informs computer of position of tripper (14) in relation to position of tripper (12) in sensor box (23). Computer relates the information to its programmed function and alters the position of an electrical current on control bar (15) to attract magnet (24) located in "handle" of yoke (17) mounted by bearing to the input drive wheels (8) and output drive wheels (20) splined on jack shafts (6) and (16) to move said drive wheels to optimum position along plane of cone (7).
