ABSTRACT:
A lehr loader or stacker for use with a conveyor for moving ware serially past the moving apron of a lehr, the loader comprising a frame adjacent the conveyor, and a pair of pusher bars on the frame alongside the conveyor and opposite the lehr apron. The bars are movable alternately transversely across the conveyor to sweep ranks of ware transversely from the conveyor onto the lehr apron for movement thereon through the lehr. The bars are mounted upon the frame for movement through the same general path, each bar being provided by a pair of longitudinally extending bar sections providing a longitudinal space therebetween. The mounting system for each bar includes arms supporting, respectively, the bar sections, one of the arms for each said bar being movable through the space between the bar sections of the other said bar as the bars move through the path.
