What fasenter did whitcomb judson patent in 1893?

In 1893, Whitcomb Judson patented the "clasp locker," which is an early version of the zipper. His invention was designed to provide a more convenient and efficient way to fasten shoes compared to traditional methods like laces or buttons. Although it was not commercially successful at the time, the concept later evolved into the modern zipper we know today. Judson's work laid the groundwork for future advancements in fastening technology.
