Abstract
A rope controller constructed without a spring or any other resilient means for controlling movement of a rope having a standing end and a free end. The rope controller is cam actuated and includes a housed cam which is journaled for movement toward and away from a clamping portion of the housing and is responsive to movement of a rope in either direction. The cam is activated to prevent movement of the standing end of the rope by tensioning the standing end of the rope. The cam is deactivated to permit movement of the free end of the rope by tensioning the free end of the rope. The cam is deactivated to permit movement of the rope in either direction by manually depressing an extension of the cam.
