A side beam, at approximately the center of gravity of the basket, is integrated with each of the side walls as well as with the cross beams to provide a unitary, rugged basket capable of vibratory movement on a support frame. A pair of cross shafts extend transversely of the screening basket and project beyond the side walls.

Adjusting mechanism is provided to adjust the relative position of the weights on the shafts to vary the angle of stroke. These weights are arranged to receive auxiliary weights to vary the amplitude of vibratory stroke as well as the shape of the stroke.

Abstract: An improved table feeder type material handling apparatus includes a support table or tray which is moved through forward and return strokes by a dirve assembly to convey ore or other material disposed on the tray in a forward direction relative to the tray. In accordance with a feature of the present invention, the stroke or distance through which the tray is moved can be varied while maintaining the stroke rate substantially constant. To provide this capability, the drive assembly includes a rotatable input member which is connected with the support tray by a linkage. A connection between the linkage and the input member is offset relative to the axis of rotation of the input member. Therefore, when the input member is rotated about its central axis, one end of the linkage is moved along a circular path.
