Abstract: An accessory (10) for a tilt tray sorter comprises a frame (11) and is adapted to be suspended by a fixture (12) from a transport mechanism of the type usually associated with conventional parcel sorting equipment. The frame (11) carries two or more tilting trays (14) which are attached by pivots (15) to the frame (11). Each of the tilting trays (14) has associated with it, a tilting mechanism (16) which includes a pair of parallel rods (17) suspended below each tray. In addition, a bracket (18) is provided above each tray (14). The bracket carries a cam (19). The cam (19) pivots an upper axis (20). The side of the cam which faces the tray (14) carries a stub (21). The stub (21) is received between the parallel rods (17). Thus, as the cam (19) pivots and returns to its rest position, the tray (14) is displaced from a level position to a tipped position and back again.
