Abstract

A vibrating screen apparatus having plural unbalanced shaft assemblies to impart vibratory movement to a screen. Each screen assembly has a gear hub to which a pair of eccentric weights are secured in flanking relationship. The shaft assemblies are drivingly connected to one another by an arrangement including an annular gear mounted on the gear hub. The annular gear has such a special relationship to the weights and gear hub, that the act of clamping the weights in place on the gear hub simultaneously clamps the annular gear in place.
