ABSTRACT:
A cable or other linear length of flexible material, such as high strength wire, is initially wound on a reel, and is unwound by the application of a force, typically a movable object moving downwards through the air under the influence of gravity. The motion of the cable in unwinding from the reel is effectively braked, or slowed, by providing a cable brake system or systems which generate resistance to the unwinding of the cable. One system entails the provision of frictional control means consisting of a soft, tough, material matrix disposed about the reel, so that the cable is imbedded in the matrix. Payout of the cable, as the reel revolves, requires the cable to be torn out of the matrix. The other system entails immersing the reel, and associated cable wound on the reel, in a viscous fluid, so that the unwinding of the cable from the reel causes the reel to turn about its axis in the viscous fluid, thereby producing resistance to motion and a braking action.
