The patent has a number of features; the angle adjustment between the head and handle, the screw adjustment of the jaw, and the interchangeable nut and pipe gripping faces for the movable jaw.

The wrench was produced without the interchangeable nut and pipe jaw faces.

The ATCO attribution for the second manufacturer is taken from Ken Cope's "American Wrench Makers 1830-1930." The tools are marked "ANY ANGLE WRENCH PAT NOV 1916 LIMA O."

The patent is a simplification of Bovee's Sept. 5, 1911 patent (no. 1,002,215).
