1. A vibratory conveyor apparatus comprising:

  • an elongated conveyor bed; and

    a vibratory conveyor drive attached to said conveyor bed for inducing vibratory motion in said conveyor bed for thereby effecting conveyance of articles in a conveying direction along said bed,said vibrating drive comprising a frame, first and second pairs of counter-rotating drive shafts rotatably mounted on said frame, and means for rotatably driving said drive shafts,said vibrating drive further including first and second eccentric weight sets, said first weight set including at least one eccentric weight mounted on each of said first pair of drive shafts for rotation therewith, and said second weight set including at least one eccentric weight mounted on each of said second pairs of drive shafts for rotation therewith,said first eccentric weight set being eccentrically mounted to induce first reciprocable vibratory forces in opposite directions along a first line and having a first maximum value, and said second eccentric weight set being eccentrically mounted to induce second reciprocable vibratory forces in opposite directions along a second line and having a second maximum value, said first and second maximum values being out-of-phase by an acute angle of rotation of one member of said first pair of counter-rotating drive shafts.
