ABSTRACT:
Apparatus for selectively by-passing, stopping, and releasing loads traveling on a conveyer having a case equipped with a stop arm and a stop lever on a pivotal stop shaft. The stop arm is swung to a stopping position above the conveyer to stop a load by pivotal movement of the stop shaft and stop lever in one direction and is swung to a non-stopping position not above the conveyer by pivotal movement of the stop shaft and stop lever in the other direction. A blocker leg is pivotally mounted at one end on the case and has an outer end engageable with the stop lever. When the stop arm, stop shaft, and stop lever are in their stopping position for the purpose of stopping a load, a spring or power means swings the blocker leg to abut its outer end against the stop lever so that when the load encounters the stop arm, the inertia and momentum forces of stopping the load is borne by the blocker leg and not borne by the spring or power means. This enables the use of a relatively weak spring and power means as the spring and power means are not required to stop and hold the load.
