ABSTRACT:
This specification describes a portable manually operated rescue and lowering device. It consists of a coaster-brake bicycle hub with its flanges extended enough to form a drum to accommodate about 40 meters of fine aircraft cable. To permit hand operation a novel brake securing and releasing lever replaces the standard bicycle sprocket. This modified assembly is mounted into a rigid frame so that the free end of the cable proceeds up away from the hub to be secured to a building part or object within the building. A fastener for hooking onto a sling is hung from the frame by means of a cable--the length of which is correct for holding a user within easy reach of the brake securing and releasing lever. With this lever, the operator can cause the cable to unwind quickly or slowly or to brake to a complete halt. To prevent the cable from accidentally unwinding constant counterclockwise tension is provided to the lever by two springs. The object of this invention is to provide a simpler, easier to operate device by means of which persons or objects can be manually lowered to safety in an emergency such as from a burning building. Another object is to make this device easily affordable, lighter and so compact that it might soon come into general use.
