Manufactured by Bemis & Call Co. - Springfield MA

Bemis' specifications recognize the A.B. Davis combination pipe and nut wrench (no. 94,085), but claim this design as an improvement on Amos Call's Aug. 28, 1866 patent (no. 57,621). This patent was the basis for B&C pipe and nut wrenches for the remainder of the tool's production. The nail-claw feature shown in the patent does not appear on known examples of the wrench. The screw holding the pipe gripping bit was a feature of early production of these tools. It was replaced by a transverse pin, which appears in ad images beginning ca. 1891. Early examples of the B&C Combination cite two patents by date: Aug. 28, 1866 57,621 and Dec. 2, 1873 (this patent). Some examples of the B&C combination also cite the McLaren patent (nos. 59,852 and RE8,064) which also is connected to combination pipe & nut wrenches produced by Tower & Lyon & Union Hardware. W.S. Bemis patents in 1893 (498,204 and 501,860) addressed manufacturing processes and modifications to the pipe gripping aspects of the wrench.

Manufactured by Bemis & Call Hardware and Tool Co. - Springfield MA

Call's patent focuses on the pipe gripping jaw element and the spring which is intended to keep that element in position when the wrench is used on pipe. The patent is essentially an improvement on the Bartholomew and Merrick pipe wrench (patent no. 6,002) manufactured by Bemis & Call. The wrenches were made with either a short adjusting nut (like pat. no. 5,707), or the longer adjusting sleeve (pat. no 23,751). The patent's features were incorporated in the Bemis & Call combination nut and pipe wrench (pat. no. 145,085).
