Description: |
| The patent presents two alternate head structures; one where the overall angle of the head is adjustable in relation to the handle, and the other with the head fixed to the handle. Both structures have a fixed jaw with one sloping & toothed face for use as a pipe wrench and a flat face at right angle to the movable jaw for nut wrench purposes. Both structures have a movable jaw which can be set to bear either against flat nut wrench face or sloping pipe wrench face. Only the "fixed head" variant shown here was produced.
A similar reversible jaw appears in the January 19, 1897 Canfield patent (no. 575,592). |
