Question

How was safety pin invented

Answer 1

The safety pin is a variation of the regular pin which includes a simple spring mechanism and a clasp. The clasp serves two purposes: to form a closed loop thereby properly fastening the pin to whatever it is applied to, and to cover the end of the pin to protect the user from the sharp point.

The Invention of the Safety Pin

On April 10, 1849, Hunt was granted US patent #6,281 for his safety pin. Hunt's pin was made from one piece of wire, which was coiled into a spring at one end and a separate clasp and point at the other end, allowing the point of the wire to be forced by the spring into the clasp.
