  • Patent number: 6705458
    Abstract: A gate (50) for a vibratory conveyor (10) is provided. The conveyor includes a conveyor bed (26) that has a surface portion defining an aperture (52). The gate includes a cover plate (54) which is in contact with the conveyor bed and arranged for movement between a first position covering a first portion of the aperture and a second position covering a second portion of the aperture (e.g., between an open position and a closed position). The gate further includes a loading system (57, 72) coupled to the cover plate to exert a force urging the cover plate into contact with the surface portion of the conveyor bed. The gate still further includes a carriage assembly (55) coupled to the loading system for moving the cover plate between the first and second positions. Material conveyed on the conveyor bed can fall through the uncovered portion of the aperture to be thereby diverted from the conveyor bed.
