  • Patent number: 3985050
    Abstract: A pivoted jaw pipe wrench having a three-arm lever which translates the swinging motion of the wrench handle to one of the two jaws for pipe-engaging purposes and is characterized by the fact that it is in the form of a laminated structure, thereby allowing it to be made thinner than the three-arm levers of previously designed similar wrenches but without sacrificing strength and consequent resistance to rupture. The space which is saved by the relative thinness of the three-arm lever allows a lever-reinforcing shroud on the wrench body to lie alongside of the lever for reinforcing purposes, the movable lever and its associated fixed shroud presenting a lever arrangement which substantially equals the transverse width of conventional one-piece cast three-arm levers for the same purpose.
