DEFINITION

Classification: 192/48.8

(under subclass 48.1) Device wherein the clutch-assemblages are provided with more than two shafts for input or output of torque, in any combination of one (or more) input shaft (s) plus two (or more) output shafts, or of two (or more) output shafts plus one (or more) output shaft (s).

(1) Note. For the purposes of this and indented subclasses, a shaft is a rotating member that transmits torque; thus a gear, pulley, drum, hub, etc., is equivalent to a shaft. An input shaft is such a member that is rotated by a source of power external to the device, and an output shaft is such a member that (a) is rotated by the claimed device AND (b) rotates a torque-using mechanism external to the claimed device. Thus, if there are rotating members that transmit torque between the input and output shafts within the device they are not counted in the number "three or more" required for these subclasses.
