  • Patent number: 4408505
    Abstract: A multipurpose ratcheting wrench is disclosed for turning components such as fire hydrant valve stems and the like. The wrench includes a lever which defines cam surfaces between the distended ends thereof. A gripping head is movably coupled to the lever adjacent the cam surfaces for receiving the component to be turned therethrough and for automatically closing toward the cam surfaces so as to engage the component therebetween. As the lever is rotated, the cam surface is pressured into communication with the component to be turned and therefore increase the grip of the wrench thereon. Two separate cam surfaces are provided, one which is adjacent to the gripping head when in the opening mode, and another cam surface which is adjacent to the gripping head located in the closing mode. A spinning handle is provided at the opposite end of the lever and is oriented generally parallel with the axis of rotation of the component being rotated.
