ABSTRACT:
A cable drum arrangement including a brake drum on a stationary support and a brake shoe on a carrier for the cable drum includes a flyweight and a compression spring radially interposed between flyweight and brake shoe which biases the brake shoe toward the brake drum by centrifugal force generated by the fly-weight while a cable unwinds from the drum. Unwinding of the last layer of cable from the cable drum releases a coupling connecting the drum to the carrier, and the resulting, limited, angular displacement of carrier and cable drum causes a cam to stress the spring and thereby to arrest the carrier. During unwinding, the spring reduces braking stress in the cable by damping radial movement of the flyweight during sudden increases in rotary speed.
