DEFINITION

Classification: 192/30

(under the class definition) Power-transmitting devices operating by friction or by interlocking for securing driving continuity as between two shafts or a pulley and a shaft or other driving and driven parts.

(1) Note. Class 464, in subclasses 30+, has overload release couplings wherein relative rotation between coupled members continues so long as an overload condition occurs. The line between Class 464, subclasses 30+, and Class 192, subclasses 56.1+, is that Class 464 takes structure wherein relatively rotatable surfaces move with respect to each other during an overload condition; but drive through such surfaces is automatically reestablished, without an additional operation, upon correction of the overload condition. Class 192, subclasses 56.1+, requires a further operation, in addition to correcting the overload condition, to reestablish the drive; such further operation being, for example, operator

assisted reengagement or reduction in rotational speed of a power input member.
