Description:
Diagonal screw adjusts the opening of two open end jaws.

Updated by Baxter's July 17, 1883 patent (no. 281,431). J. Ashton Greene's Feb. 19, 1884 patent (no. D14,756) is a design enhancement that coincides with the wrench being produced by Greene, Tweed & Co. of New York -- they had registered "labels" for both forms of Baxter wrenches at the U.S. Patent Office in March, 1883.

George C. Taft's Dec. 14, 1869 patent no. 97,988 presents an alternative screw arrangement for a diagonal adjusting "S" wrench.
