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.

Abstract: A method and apparatus for evacuating and transferring liquid waste comprising a pump assembly that is connected to a holding tank and to a liquid container; the pump assembly being mounted on a wall and elevated above the holding tank; the pump assembly including a flexible hose detachably mounted on one end to said pump assembly and which is adapted to be connected at a second end to an aperture in the container, the aperture in the container being connected to a suction mechanism extending to the bottom of the container to permit the pump assembly to drain substantially all of the liquid waste from the liquid container and into the holding tank.

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.

Abstract: Tree climbing apparatus includes a seat, a rope supporting the seat and a cleat. One end of the rope supports the seat, a standing portion of the rope extends upwardly from the seat; the rope passes over a branch, and a running portion extends downwardly and through a uni-directional cleat; a a link supports the seat from the cleat. The cleat is laterally removable from the running portion, for replacement by a latching rope extending from the seat to the suspension rope running portion.
