Abstract
An assembly for lowering a person to safety from a building under a descent operation that is controlled by the person without requiring such person to manipulate a hand operated device, such as a lever. The assembly includes a rope which is connected to a storage drum via guide rollers and which passes through a gap defined by a cam element. The cam element is biased to rotate, and when in a first position jams the rope element against further movement off of the storage drum. The cam element automatically moves into the first position and is moved out of that position when the person jumps upwardly.
