Abstract
Bearing failure and noise generation problems of prior art, vibratory feeders are eliminated in a construction including a bed (10) having an elongated, generally horizontal feeding or conveying surface (56) having opposed ends (52) and (54). Spaced resilient isolation elements (58) mount the bed (50) above the underlying terrain (68) and a rotatable shaft (74) with an eccentrically mounted weight (56) is journalled to the bed (50) for bi-directional rotation about a generally horizontal axis. A pair of dynamic balancers (82), (84) are connected to the bed, one on each side of the shaft (74) and serve to reduce the vertical component of vibration imparted to the surface (56).
