The Sharps Rifle Company failed in 1870, and the Weed Sewing Machine Company took over its factory. The invention of a new type of sewing machine led to a new application of mass production after the principles of interchangeability were applied to clocks and guns. The Weed Company played a major role in making Hartford one of three machine tool centers in New England and even outranked the Colt Armory in nearby Coltsville in size. Weed eventually became the birthplace of both the bicycle and automobile industries in Hartford.
