DEFINITION

Classification: 475/198

VARIABLE SPEED OR DIRECTION TRANSMISSION COMBINED WITH DIFFERENTIAL:

(under the class definition) Subject matter wherein a differential transmission* is associated with another transmission capable of speed ratio* change or capable of reversing the direction of relative rotation between input and output shafts of said other transmission.
