In automatic loading from gravity conveyor to the ele-vator it is important that the push-bar take a positionsquarely behind each box. Various types of selective de-vices are used to accomplish this. Spring pieces placedat the foot through which the box passes serve the doublepurpose of starting the box properly up the center of theelevator runway and, for fairly uniform sizes, they holdback any box that has not been securely caught by thepush-bar.
