ABSTRACT:
An apparatus which automatically prevents the rotation of a rotary blade or the like when a power plant is operating at idling speed and which drivingly engages the rotary blade when the power plant is driven at a predetermined speed which is greater than idling speed. The apparatus includes a housing having a generally frusto-conical portion and a brake shoe which engages a fixed brake band under spring pressure when the power plant is at idling speed and a plurality of weights which move outwardly by centrifugal action into engagement with the housing to move the housing away from the brake shoe and provide a drive connection to a rotary blade when the speed of rotation of the power plant is increased a predetermined amount.
