Abstract: An improved circular sorter includes an integral, rotatable, circular ring on which tiltable tray carriages are mounted. The ring is driven by a peripheral drive to convey the tiltable trays past loading stations, where articles are placed thereon, and then to sort locations where articles are selectively discharged by tray tilting, to either the inside or outside of the ring. Both loading and sort locations can be disposed interiorly or exteriorly of the ring. Yieldable rollers support the ring and operatively accommodate variations in vertical disposition, while a combination of fixed and yieldable rollers guide the ring in a horizontal path and accommodate ring pitch inaccuracies.
