Abstract
In a basket centrifuge, a hollow boss extending downwardly through a hole in the stationary frame cover is secured to the cover, and a shaft extending downwardly through said boss is mounted for rotation in a sleeve secured to the upper portion of the boss, a scraper being carried by the shaft below said boss. Means are mounted on said sleeve for rotating the shaft in opposite directions to swing the scraper toward and from the annular wall of the rotating basket, thereby scraping material deposited centrifugally on said wall. A collar surrounding the shaft below said boss has annular means in sealing engagement with the shaft, and releasable means are provided for urging the collar upwardly in sealing engagement with said boss.
