ABSTRACT:
A fire escape device includes a housing with a reel journalled for rotational movement within the housing. A cable is fixed at one end thereof to the reel and is wound upon the reel with the other end thereof extending through an opening in the housing. The housing can be connected to a fixed position on an elevated structure and a harness which is carried at the free end of the cable is used for supporting a human body. A fluid pump is carried by the housing for pumping fluid from a sump reservoir through an orifice. The rotor of the pump is coupled with the reel for retarding and impeding free rotational movement of the reel so that the cable unwinds at a controlled rate of speed which is in direct proportion to the amount of fluid being pumped through the orifice.
