ABSTRACT:
A variable centrifugal brake comprises a driven shaft carrying a disc with centrifugally-acting bob weights which bear against an axially displaceable bush, which in turn bears against a forked lever assembly, in turn bearing against a further lever carrying a friction lining engaging the periphery of the disc. The brake may be used in an exercise machine having a drum around which a pull cord is wound and a transmission for transmitting drive from the drum to the shaft of the brake.
