Description:
Adjusting nut with interrupted threads can slide freely on the main shank, or adjust a partial turn when engaged with the threads on the shank. A spring-tensioned lever with projection acts to hold the adjustment. Teeth on the exterior of the adjusting nut have a "one-way" bevel so the nut can be tightened while the lever is pressing against it.

Produced as a nut wrench, pipe wrench, and combination pipe and nut wrench by the Adjustable Wrench and Specialty Mfg. Co. which formed at Oshkosh, WI and moved to Harvard, IL.
