An early device superficially similar to the zipper, "an Automatic, Continuous Clothing Closure", was patented in the United States by Elias Howe in 1851. Unlike the zipper, Howe's invention had no slider; instead a series of clasps slid freely along both edges to be joined, with each clasp holding the two sides together at whichever pair of points along them it was located. The clasps were joined together by a string, which, when pulled taut, caused the clasps to be evenly spaced along the closure, thus holding the two edges together. Pulling in the other direction caused the clasps to become bunched up at one end, by which means the device was opened.

The true zipper was the product of a series of incremental improvements over more than twenty years, by inventors and engineers associated with a sequence of companies that were the progenitors of Talon, Inc. This process began with a version called the "clasp locker", invented by Whitcomb L. Judson of Chicago (previously of Minneapo ...more

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.'

Forty-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 o ...more
