Manufactured by ROXBY WRENCH CO. - Boston MA
Assigned to Trimont Manufacturing Company - Roxbury MA

The basic principle in this patent is side lugs to prevent lateral movement of the adjustable jaw. The drawings show a pipe wrench modification of the TRIMO nut wrench of the period; the specifications state the configuration would apply to pipe or nut wrenches. Kenerson's Jan. 4, 1927 patent 1,613,229 shows a further refinement of the "extended length frame with side lugs" for a pipe wrench in the drawings, although that patent is for the "nut guards." Trimont's "ROXBY" "Pat Apld For" pipe wrench of the late 1920s appears to incorporate features from these patents. A ROXBY image in a 1928 TRIMONT catalog appears to show a January 1926 patent date.
