Abstract
An automatic variable speed centrifugal clutch with 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. Slide rails slidably inserted through slide rail holes in the clutch drum and spacer, and connected at their ends to the clutch plate and spindle flange rotationally interlock the clutch assembly yet allow for longitudinal displacement of the clutch drum and spacer means relative to the spindle flange. 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.
