ABSTRACT:
An apparatus is provided for letting a person down from a substantial height. The invention includes: a rotatably mounted reel for retaining an elongate extension member adapted to be connected to the person to be let down; a brake for reducing the rate of rotation of the reel, the brake including a brake drum and a pair of brake shoes mounted to rotate with the reel; a governor including a pair of radially inwardly articulated flyweights extending between the brake shoes, the articulation permitting the flyweights to be displaced radially outwardly as the rate of rotation of the brake shoes and the reel increase, to displace the brake shoes radially outwardly whereby the pressure of the brake shoes against the brake drum and the resulting brake is increased as the rate of rotation of the reel increases; and a crank mounted to the apparatus for permitting the reel to be rewound onto the reel.
