A plurality of drive cams each sliding up and down on its own drive shaft, and each having a helical slot on its outer surface, rotate as the shafts are rotated. Trunions extending from the trays engage the helical grooves in the cams, and they, along with the tray to which they are connected, move up or down as the cams rotate. The sorter has improved capacity while yet permitting access between trays. It is simple and positive in operation and provides sorting action in both the upward and downward movement of the cams on the driveshafts. | |
