A vibratory parts feeder includes a feeder bowl having a plurality of lugs affixed between the bottom wall and the cylindrical outside wall of the feeder bowl. Corresponding to each lug is a fastener that engages the lug through a corresponding opening in a top member, thereby securing the feeder bowl to the top member of the parts feeder. The top member is, in turn, supported by a plurality of drive springs connected between the top member and a base member. The drive springs attach to spring mounting pads incorporated within the top member that are radially outboard of the attached feeder bowl, A plurality of electromagnetic devices are mounted on the base member in cooperating relation with a corresponding plurality of ferrous striker plates attached to the top member for causing the rotation of the top member relative to the base member. The electromagnetic devices operate with the drive springs to induce both axial and rotational movement:, or oscillating motion of the top member, and thereby the feeder bowl, relative to the base member.
