  • Patent number: 5127507
    Abstract: An offset assembly (20) for a gravity-conveyor chute (10) includes offset upstream and downstream tubes (18 and 22) which are hingedly attached one to the other, with an upstream end opening (66) of the offset downstream tube being significantly larger than outer dimensions of a downstream end (44) of the offset upstream tube. The offset upstream and downstream tubes are rectangular in cross section with each including hinge mounts which extend laterally, outwardly, from outside surfaces of panels thereof. The downstream end of the offset upstream tube terminates in a plane which forms an angle with an axis of elongation of the offset upstream tube. The offset upstream tube has a side opening with a ledge and a door thereat.

  • Patent number: 5090546
    Abstract: A gravity conveyor chute section (10) includes a door/ledge assembly (20), having a ledge (30) which is hingedly attached to a sidewall (12) of the chute section below a side opening (16) into the chute section and first and second side supports (56, 58), which extend from side edges (32, 34) of the ledge to the chute sidewall beyond side edges (36, 38) of a front panel (18). The ledge can be moved to a laterally-extending position for forming a ledge below the side opening and to a closed position for closing the side opening. When the ledge is moved to the closed position, the side supports move along side panels (22, 24) of the sidewall beyond the first and second side edges of the front panel. A door (68) is hingedly mounted on the ledge for being selectively rotated to the laterally-extending position with the ledge and to a closed position with or without the ledge.
