This patent was cited as prior art in patent no. 2,555,395.
The drawings and specifications cover a wide variety of instances of the general principles claimed, indicating contemplation of potential competition with "Stillson," "Trimo" and G.T.D. "Little Giant" and other similar pipe wrenches already in the market. Compare this patent to Walworth's WALCO pipe wrench based on patent nos. 1,711,083, 1,862,001 and 1,862,002.
