ABSTRACT:
A vibratory apparatus is provided with an improved structure for varying the lead angle and the amount of the vibratory force by angularly and radially positioning a movable weight relative to a fixed eccentric weight. The apparatus comprises a plate supporting the fixed eccentric weight on the shaft in one of several positions with a line through the center of gravity of the fixed weight and the axis of the shaft forming a base line. The movable weight is carried by a cylinder attached to the plate so that the longitudinal axis of the cylinder passes through the axis of the shaft at an angle to the base line. The movable weight in the cylinder is movable from a position on one side of the axis of rotation to a second position on the opposite side of the axis of rotation, the movement being linear and radially across the axis of rotation. The resultant of the forces generated by the fixed weight and by the movable weight upon rotation of the apparatus will determine the lead angle and the amount of the vibratory force.
