Abstract: A mounting means for supporting and positioning the elongated brush roll of a suction cleaner in the suction chamber or nozzle of the cleaner so that the brush roll may be rapidly and easily mounted in or removed from the suction chamber. Guide and bearing surfaces are defined on a plurality of bosses on the portion of each side wall of the cleaner base which defines the suction chamber, and the external surfaces on a hexagonal boss at each end of the brush roll coact with the guide surfaces on the bosses to guide the direction of movement of the brush roll during installation and removal thereof from the suction chamber and with the bearing surfaces on the bosses to locate the brush roll in its operating position in the suction chamber. The guide surfaces are inclined toward the rear of the cleaner base so that the brush roll is held in its operating position in the suction chamber solely by the tension of the brush roll drive belt.

Abstract: A cylindrical brush, turnable about a horizontal axis in a housing, has hollow end portions extending along said axis. An arrangement for adjusting the brush relative to said housing and for removing it therefrom, is mounted in said hollow end portions of the brush. The adjusting arrangement comprises a pair of eccentrics respectively arranged in the hollow end portions of the brush, and having end portions normally arranged in openings in adjacent side walls of said housing.
