Elias Howe, who invented the sewing machine received a patent in 1851 for an 'Automatic, Continuous Clothing Closure.' Perhaps it was the success of the sewing machine, which caused Elias not to pursue marketing his clothing closure. As a result, Howe missed his chance to become the recognized 'Father of the Zip.' \n\nForty-four years later, Mr. Whitcomb Judson (who also invented the 'Pneumatic Street Railway') marketed a 'Clasp Locker' a device similar to the 1851 Howe patent. Being first to market gave Whitcomb the credit of being the 'Inventor of the Zipper', However, his 1893 patent did not use the word zipper. The Chicago inventor's 'Clasp Locker' was a complicated hook-and-eye shoe fastener. Together with businessman Colonel Lewis Walker, Whitcomb launched the Universal Fastener Company to manufacture the new device. The clasp locker had its public debut at the 1893 Chicago World's Fair and met with little commercial success.
