Abstract
701,484. Sifting-apparatus. MARE, E. May 7, 1952, No. 11551/52. Class 117 A shaking screen comprises a screen and frame resiliently and adjustably carried between a plurality of pendent chains, ropes or like flexible supports which are anchored at both ends and an eccentrically weighted driver flywheel attached to the frame by plummer blocks, and driven by an electric .motor through universal couplings so that the screen is given a regular elliptical movement which sieves material on the screen and stratifies material which does not pass through. The anchor points may be adjustable in position and the supports may comprise extensible springs 7 or be themselves of elastic material. The attachment points 6 of the screen frame to the supports may be individually adjustable and the drive shaft 16 splined: to render it telescopic. Shims may be inserted between the screen frame and plummer blocks to vary the angle of the drive shaft relative to the plane of the screen and give the screen a vertical as well as planar vibration. Eccentric weights 13 may be radially adjustable in slots in the flywheel.
