resilient means generally denoted as the numberal 26 such as a plurality of coil springs providing for unrestrained motion of the housing 12 except for the dampening provided by the resilient means 26 the housing 12 can be slightly declined from the upstream housing end 18 to the downstream housing end 20 such that the housing longitudinal axis 28 is declined to improve the flow of media and workpieces along the length of the elongated housing 12 from the upstream housing end 18 toward the downstream housing end 20 to the outlet 20 vibratory generating means generally denoted as the numeral 30 is structurally associated with the housing 12 for generating a vibratory force and imparting the vibrating force to the housing 12 to vibrate the workpieces and media in the housing 12 with continued reference to fig1 and 2 the vibratory generating means 30 is mounted to one side of the housing 12 by a bracket 32 further the vibrating generating means 30 comprises a first eccentric rotatable weight 34 and a second eccentric rotatable weight 36 both operatively associated with a drive motor 38 so that the first and second weights counter rotate that is as seen in fig2 the first eccentric weight 34 is rotated in a counter clockwise direction and the second eccentric weight 36 is rotated in a clockwise direction the first.
