Abstract
A high rise fire escape mechanism uses a flat cable having notches to lower the victim. The cable is wound around a notched sprocket mounted inside a housing on a first axle. A second axle and an escapement mechanism mesh with the first axle to mechanically control the rate of descent of a victim to about four (4) feet per second.
