The Clasp Locker was actually a complicated "Hook and eye shoe fastner and his patent in 1893 didn't even use the word zipper.

"Whitcomb L. Judson invented the zipper and YKK is the Japanese company that makes them.
Whitcomb L. Judson was a lover of gadgets and machines and the idea for his "clasp locker" came from when a friend had a stiff back from trying to fasten his shoes. Judson's clasp locker was used mostly on mailbags, tobacco pouches and shoes. However, his design, like most first inventions needed to be fine-tuned.
A more practical version came on the scene in 1913 when a Swedish-born engineer, Gideon Sundback revised Judson's idea and made his with metal teeth instead of a hook and eye design. In 1917, Sundback patented his "separable fastener."
The name changed again when the B. F. Goodrich Co. used it in rubber boots, galoshes, and called it the "zipper" because the boots could be fastened with one hand."
and what did we prove?
nothing.
