Abstract A vibratory conveying apparatus includes a trough operatively associated with a vibratory drive assembly for conveying pieces along the trough. The vibratory drive assembly includes a base member and a vibratory drive mounted to the base member. The trough is operatively associated with the vibratory drive to be driven into vibration substantially longitudinally with respect to the base member. First and second flexure members or bars extend longitudinally of the base member on opposite lateral sides of the base member, the bars connected at base ends to the base member. At least one leaf spring extends laterally across the base member, the leaf spring connected at opposite ends to distal ends of the bars and operatively connected at a center thereof to the trough. The flexure members provide increased flexibility at the leaf spring connections to increase useful spring life.
