Abstract
A progressive clutch includes a centrifugal clutch 10 attached to a drive shaft and inserted into a clutch housing assembly 16 to engage with clutch material 28 during low rpm operation. As the rpm of the input drive shaft 2 increases, the centrifugal force on pellets 32 overcomes the force of compression springs 34, and extension springs 40 pull a pin engagement assembly 30 towards the clutch housing assembly 16 thus engaging pins 38 into elongated holes 42 to provide positive drive from the drive shaft 2 to the driven shaft 21.
