A tripping and re-cocking mechanism ( 202 ) is applied to an apparatus ( 200 ) by which a shifted apparatus ( 200 ) is re-positioned for operation after having shifted from its operational mode. A pivot mount ( 205 ) of a second-class lever ( 204 ) is connected to a member or casting ( 209 ) of apparatus ( 200 ). At the point of resistance of lever ( 204 ) a roller bearing ( 215 ) cooperates with, by latching onto a platform ( 217 ), the platform ( 217 ) on a standard ( 221 ) that is part of apparatus ( 200 ), to cock mechanism ( 202 ) so that apparatus ( 200 ) is returned to its operational position. The shaft ( 228 ) of an energized solenoid ( 227 ) releases roller bearing ( 215 ) from its latched seat on platform ( 217 ) in the operation of apparatus ( 200 ) thereby shifting it to a non-operational position. Arm ( 232 ) re-cocks mechanism ( 202 ) to shift apparatus ( 200 ) again into its operational position.
