.~ Control by direction of rotation of shaft or spindle
DEFINITION
Classification: 200/61.39
(under subclass 52) Apparatus in which a circuit is made or broken in response to a mere change in direction of rotation (not to angular acceleration or deceleration) of a shaft, the manner of making or breaking the circuit consequent upon rotation of the shaft in one direction differing from that corresponding to rotation in the opposite direction.
(1) Note. Although it is a form of acceleration, the change in direction of rotation involved in a shaft's going from rest to rotation in either direction is considered a mere change of direction for this subclass.
(2) Note. The difference in function, dependent upon direction of rotation, may comprise the closing of alternative circuits, for instance; or by way of additional example, the making of a circuit corresponding with rotation of a shaft in one direction and the breaking of such circuit upon rotation in the opposite direction.
