Abstract
In a sifting machine having a driven vibratory screen assembly comprising a so-called sifting basket of which a screen forms the base, the screen is releasably located by a plurality of spaced bars which extend across the screen and project at their ends through side walls of the basket. The projecting end portions of the bars are bolted to external supports on the side walls, and the bars carry spring-loaded plungers which press the frame of the screen against internal ledges on the side walls.
