ABSTRACT:
An improved classifying apparatus and assembly for the tensioning of vibratory screens includes a rigid frame, a pair of classifying screens in the frame and means for tensioning the screens. The improvement in the means for tensioning the screens includes a stationary anchor at one end of the screens and elongate rotatable elements adjacent the other ends of the screens. Levers are mounted to the ends of the rotatable elements outside of the frame and a tensioning cable extends between the levers. A tensioning member is positioned in the cable which, when adjusted, rotates the rotatable elements to simultaneously and uniformly adjust the tension on the screens.
