Provides for adjusting wrenches by aligning two matching "half-wards" and inserting a locking pin or key. The "half-wards" are spaced differently on the two mating segments forming the wrench, the spacing designed to result in openings corresponding to standard sizes. The principle was refined and provides the adjusting means for the combination nut and pipe wrench in GB-190814296.

Abstract: The primary object of this invention is to provide a simple and highly efficient scraper for removing mud, dirt, gravel, etc., from the periphery of a wheel or roll of a road- roller. And further objects are to secure a uniform pressure of the scraper against the roll; to enable this pressure to be readily increased or lessened; and to enable the blade to be held out of contact with the roll without having to be removed from the machine. Claim: A scraper comprising a fixedly-supported shaft, a scraper blade, a support therefor journaled on said shaft, a plate spring slidably secured to the scraper blade, a collar loosely-fitted on said shaft, and to which said spring is secured, and means for adjustably holding said collar.
