Overlapping rings are supported by spiders one above the other, from a central shaft, andhave beater arms projecting towards the shaft; 20, and rotated with it. The upper end of theshaft is fitted eccentrically into the disc, 11, sothatas the latter is rotated the agitator is swung. alternate rings ax-e rotated. The material to betreated is fed into the top of the hollow spaceenclosed by the rings and passes downwards,to a supporting plate below, from which it isdischarged by a scraper.—W. H. C.
