Description:

The pivoting handle adjusts the sliding jaw by a curved gear-tooth segment engaging rack teeth on the bar of the jaw. The combination includes wire cutter, fold-out punch and chisel in the end of the handle, a screwdriver on the end of the lever handle, and insertable pipe jaw face. The basic wrench is a modification of Huston's Oct. 21, 1890 patent (no. 439,071).
