Abstract: A solenoid actuated diverter mechanism including a pivoted arm selectively operable to pass or divert articles moving along a conveyor path. Resilient linkage preloaded by solenoid actuation for swinging the arm into a final "over-center" diverting position yields to intercepting engagement of a passing article occurring before the final diverting position is reached. A spring returns the arm from diverting to passing position upon de-energizing the solenoid. Load reaction on the over-center linkage delays return until completion of any diverting engagement which may have started prior to de-energizing the solenoid.

Abstract: A solenoid actuated retractable stop including a pivoted arm selectively operable to block or pass articles moving along the surface of a roller conveyor characterized by a positive stop linkage adapted to resist impact engagement and cumulative loading of articles travelling on a conveyor including a pivoted mounting for the stop with lever linkage adapted to raise the stop above the conveyor surface level, a positive latch mechanism for holding the lever linkage in the raised stop position, a solenoid adapted to release the latch mechanism so that forward force of an article against the stop will cause it to pivot to a retracted position below the level of the conveyor and remain there during the overpassing of any article load, and a spring return mechanism adapted to raise the stop and reengage the latch upon de-energizing the solenoid subject to completion of any overpassing of any article load.
