ABSTRACT:
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.
