ABSTRACT:
The subject to this patent application is apparatus for mechanically varying the speed of a disk, such as a floor treating pad (18), mounted for rotation about the axis of elongation (20) of a shaft (38) powered by a fixed speed motor. The pad (18) is supported by a hub (40) disposed axially intermediate a flange member (74) fixedly attached to the shaft (38) and a sheave (66) disposed for rotation about the shaft (38), but at a speed different than that of the shaft (38). The invention includes means for keying the hub (40) to either the flange member (74) or the sheave (66), depending upon the desired speed of operation of the floor treating machine (10) of which the pad (18) is a part.
