Abstract
A hand operated apparatus is disclosed for controlling, hauling in, paying out or securing a line. The apparatus includes rope engaging cammed surfaces eccentrically mounted for rotation that permit the line to move in one direction but prevents it from moving in the other direction unless lever means, acting against a spring bias, rotate the cam surfaces away from contact with the line permitting the line to run freely through the apparatus. A fail safe position is provided in that if the lever is clutched too tightly, it will over-travel the line releasing position and engage the line on a second surface of the cam. As an added feature a mechanism is provided for automatically engaging and disengaging the device from the bite of a line.
