  • Patent number: 5113726
    Abstract: A utility tool (10) for gripping a pipe nut and rotating the pipe nut about a pipe. The utility tool (10) includes a pair of cooperating jaw members (20 and 34) pivotally connected at one end (26 and 42) such that the jaw members (20 and 34) may be opened to receive a pipe nut (130) and closed to grip the pipe nut (130). A fixing device (54) is connected to the jaw members (20 and 24) such that the jaw members (20 and 24) may be selectively fixed in the closed position. A lever (14) is included to apply torque to the pipe nut (130) thereby causing the pipe nut (130) to revolve about a pipe (132). A ratchet (18) is included to connect the lever (14) to the jaw members (20 and 34) such that the lever (14) may be selectively engaged and removed and such that the lever (14) may move freely about the jaw members (20 and 34) in a selected direction (136) and in the opposite direction (134) the lever (14) may engage the jaw members (20 and 34) in order to rotate the pipe nut (130).
