In 1896, the first U.S. patent for a hookless fastener based on a slider was issued to Whitcomb L. Judsen of Chicago Illinois (No. 557,207). It was designed for fastening shoes, whereby two metal chains were fastened together by the movement of a slider. He held a previous patent (No. 504,038 issued 29 Aug 1893) for a hookless fastening design for shoes, which used a clasp locker and unlocker.
