ABSTRACT:
A safety device for preventing injuries to a worker as a result of a fall includes a housing which is intended to be supported at an elevated position where the worker is working and a cable which is adapted to be connected to a harness or belt worn by the worker. The housing includes a spring driven drum therein which normally keeps the cable wound thereon but which allows the same to be withdrawn slowly from the housing as more cable is needed by the worker. A centrifugally operated brake senses an initial quick withdrawal of the cable from the housing which results from the worker falling and stops further withdrawal therefrom to thereby prevent the worker from falling further. A hand operated winch mechanism carried by the housing allows a fellow worker to raise the fallen worker to safety.
