RE: "textile wrenches"
They were "textile wrenches" because they were used in the textile mills of New England. The looms and other machines in the mills used
square nuts, and the 22½° offset on each end apparently lent itself well to their use on the square nuts used on the machinery. The Williams Company made many of them stamped with the names of the textile (or other) mills in which they were used.
