A stationary shaft supports a fluid-tight rotatable drum which receives an elongated flexible restraining member. The shaft has a threaded portion which receives an actuating nut connected to rotate with the drum through a detent mechanism. Spaced compression springs extend axially between the nut and a stack of interfitting annular brake disks and brake plates, with the disks splined to the shaft and the plates rotatable with the drum. The stack is immersed in an oil-shear cooling fluid that contacts the drum, and the nut and springs are effective to compress the stack with increasing force in response to rotation of the drum for progressively increasing the resistance torque on the drum as the restraining member is pulled from the drum. The detent mechanism limits the compression force on the stack and the tension force on the restraining member while the drum continues to rotate.
