Five years after being granted a patent for the first practical sewing machine, Howe patented his design for a zipper-like garment fastener. However, he never put much effort into marketing this invention, perhaps due to the great success of his sewing machine, and today, credit for the zipper's development is largely given to Whitcomb Judson, who demonstrated his innovative slide-fastener design 42 years later at the World's Columbian Exposition of 1893. How did the zipper get its name? Discuss (http://forum.thefreedictionary.com/postst48526_Elias-Howe-Patents-a-Precursor-to-the-Zipper--1851-.aspx)
