Abstract: A safety governor operable on failure of the primary governor to arrest operation of the motor with which it is associated. An annular spring-washer, that includes weights supported peripherally distributed about its face, is secured to the drive spindle proximately displaced opposite inlet air passages to the motor. In response to centrifugal forces of rotation, the weights bend or deflect the spring-washer in an axial direction increasingly toward the inlet air passages until, at a predetermined overspeed, passage closure is effected interrupting air supply to the motor.
