Safety pin patent application drawing 1849
WebOct 19, 2024 · This problem was solved by the American mechanic Walter Hunt, in 1849. Hunt patented the safety pin, which he called a dress pin. The design was ingenious because the pin was constructed from a single measure of wire. Hunt used brass, coiled it at the center and formed a clasp on one end, shielding the wearer. WebHunt quickly became embroiled in this when he attempted to advance his claims on the design. Unfortunately, Hunt's designs were found to have several faults and flaws and Howe was awarded the patent for the improved machine. But it was Hunt's invention of the safety pin that really shows just how bad he was at thinking ahead.
