Abstract
A spring clutch where an input shaft and output shaft are connected and disconnected with each other through a coil spring. The coil spring is secured at one end to the output shaft and is freely disposed over the input shaft at its other end. A centrifugally responsive pawl is mounted to engage the coil spring at the end disposed about the input shaft when said input shaft is rotated at or above a predetermined speed to cause said coil to be wound and tightened about the coil spring, thereby connecting the input and output shaft.
