ABSTRACT:
An automatic variable speed centrifugal clutch belt tightening assembly is characterized by even transmission of rotational drive to a pair of belts and includes a rotating spindle and clutch plate having an adjustable centrifugally operable belt tightening mechanism. The belt tightening mechanism includes a clutch drum and a spacer which define recesses for receiving the belts to be driven. The spacer is mounted on the spindle by a bearing assembly affording free rotational and limited longitudinal movement relative to the spindle. As the spindle rotates, the clutch drum presses the spacer against a flange of the spindle to evenly drive the belts while compensating for differences in belt size.
