Patent for a new and improved pipe-wrench. This design consists in "the handle having the integral L-shaped foot at its end forming the rigid jaw of the wrench, said foot or jaw having its inner face curved, so as to receive and provide a bearing for the pipe, and its outer face at right angles to the handle, and said face being serrated, combined with the C-shaped swinging jaw pivoted at one end to the handle by a single bolt, and having its entire inner face serrated from the pivot-point to the outer end, and the teeth along the outer edge of the handle in close proximity to the rigid foot" (lines 12-24).
