ABSTRACT:
A fire escape device is disclosed for use in lowering persons from high-rise structures. The device comprises a frame having a spool rotatably mounted thereon, with a cable being wound around the spool. There is a first sprocket wheel fixed to the spool and a second sprocket wheel disposed on a fluid pump adjacent the spool. The first sprocket rotates as the cable is dispensed from the spool, thereby driving the small sprocket wheel on the fluid pump. The small sprocket wheel is provided with means for moving fluid through a fluid circuit in which a pressure compensated flow control valve is disposed for maintaining a constant speed of revolution of the spool independently of the weight of a person being lowered to the ground by the cable being unwound from the spool. In some embodiments a fluid reservoir is provided in the fluid reservoir for cushioning shock waves and breaking up bubbles. A rescue collar attached to the cable can be stored in a box around the frame, the box having a trap door in the bottom through which the collar falls when a rip cord is pulled.
