ABSTRACT:
A tool for forming a controlled bend in a wire to be positioned around a terminal screw or post. The tool has a wire bending head at one end of a shaft which has a handle at the opposite end, the wire bending head including a post coaxial with the shaft and an arcuate flange outwardly of the shaft. A second flange is spaced from the first flange, and the two flanges provide stops. The end of a wire is placed adjacent to the post and is inserted between the flanges; in an alternate embodiment, there is a single flange with a transverse opening in which the end of the wire is placed. The tool is rotated while the wire is held, or the wire may be moved with or without tool rotation, so that the wire is bent around the post. Bending continues until the wire engages a second stop, which is located to position the two legs of the bent wire in a desired relative position, which may be substantially parallel. A generally S-profile wire pusher element having a transverse annular element is provided for assisting in bending stiff wire. The tool may have coplanar blades for turning a screw.
