ABSTRACT:
A centrifugal braking device of compact design uses at least one centrifugal body pivotally connected to a sprocket to shift from a rest position to a stop position to brake movement of a rotary shaft under certain conditions. Thus, depending upon the rotary speed and/or acceleration of the rotary shaft, the centrifugal body will pivotally shift from a rest position to a stop position to prevent rotation of the shaft. A substantially stationary annular member disposed concentrically around the hub of the sprocket has an inner bore which defines a stop for the centrifugal body when said body is shifted outwardly. Said outer bore also defines a cam surface to aid displacement of the centrifugal body from the stop position to the rest position when the shaft is rotated in a specified direction.
