  • Serial release mechanism and drainage monitor embodying the same
    Patent number: 4309913
    Abstract: A serial release mechanism, a serial release method, and a discharge monitor including the mechanism, which mechanism includes first and subsequent actuators slidable in a frame between working and withdrawn positions, springs urging the subsequent actuators into their working positions, latch tabs carried by the subsequent actuators and triggers resiliently pivoted to the frame for releasably retaining the subsequent actuators in their withdrawn positions, a shaft of noncircular cross section and a plurality of saddles for releasing the triggers of the subsequent actuators and having operating fingers and being rotatable with the shaft and slidable therealong between first positions in which they are aligned with the triggers and second positions in which they are not so aligned, saddle springs resiliently urging the saddles along the shaft into their second positions, and shifter springs carried by the actuators and the frame, and effective when any actuator is in working position to displace the succeeding
