Abstract: A wrench is disclosed having hinged jaws which may be opened to be placed about an obstructed bolt, ferrule or other threaded connector. Once placed about the connector the jaws of the wrench are closed to provide contact between the interior flats of the wrench and the corresponding flats of the connector. Complemental elements moveable in parallel planes orthogonal to the jaws pivot axis and drive axis project from respective jaws and provide a means for engaging a torque-applying tool. Upon closure of the wrench jaws and elements are brought into register to permit attachment of the tool and thereby lock the hinged jaws of the wrench together.

Abstract: This device is designed to keep fishing lines from tangling and also prevents fish hooks from accidentally becoming embedded in articles, people, upholstery, etcetera. The device utilizes a pair of inner sleeve halves that are of foam rubber form engaging with barbs of fish hooks, and a groove is provided for receiving a fishing pole. The design further includes a pair of outer sleeve halves that are hinged together to enable the device to open and close on the fishing pole, and a fishing line and a leader of a fish hook are held against the pole by the device, the device being held closed on the pole by a pair of attached hook and loop pile fasteners.

Abstract: Roof-mounted devices for providing drainage channels through ice dams that may form on a roof under winter conditions are spaced along the margin of the roof, each device comprising an elongated, heat-collecting metal plate which is installed in a transversely upright position between an adjacent pair of shingles. The plate extends longitudinally in a downward direction along the slope of the roof with its lower end portion projecting clear of the roof. Opposed, major vertical surfaces are thus presented by the plate and are black in color to maximize the collection of solar energy thereby causing a drainage channel to form along the surfaces through dams of ice or snow.
