Vacuum cleaner tool having a two-position rotary brush

Abstract

A vacuum cleaner tool is provided which comprises a housing and a motor positioned in the housing, the motor having a driving pulley connected to the output thereof. A rotary agitator brush is mounted in the housing and has a portion thereof extending from the housing for contacting a surface to be vacuumed. The brush has an axle which extends therefrom along the axis thereof. A drive belt couples the pulley to the brush and an end cap is mounted on the axle of the brush for mounting the brush in the housing in two positions. The brush extends a smaller distance from the housing in the first of the two positions. The center of the end cap is positioned with respect to the axis of the brush such that when the cap is rotated 180.degree., the brush is shifted between the two positions while the distance from the center of the pulley to the axis of the brush is maintained constant. Further, the brush has first, second, third and fourth axial bores which are aligned with the axis thereof, and the axle is positioned in the first axial bore and extends therefrom. A bearing is fixed to the periphery of the second axial bore for rotatably mounting the brush on the axle. The bearing includes a flange which extends radially from the one end thereof, with the flange being positioned in the third bore. The end cap is mounted on the portion of the axle which extends from the first bore.
