CENTRIFUGAL FREE-WEIGHT FRICTION CLUTCH MECHANISM

Drum 1 is keyed to the driven shaft and rotates about fixed axis A. Spider 4 with pins 3 is keyed to the driving shaft and rotates about axis A. Weights 2 slide freely along pins 3 of spider 4. When the driving shaft reaches a definite speed, weights 2 are pressed against the drum by centrifugal force and rotate the driven shaft.
