Thomas Blanchard (inventor)

Thomas Blanchard (June 24, 1788 – April 16, 1864) was an American inventor who lived much of his life in Springfield, Massachusetts, where in 1819, he pioneered the assembly line style of mass production in America, and also invented the first machining lathe for interchangeable parts. Blanchard worked, for much of his career, with the Springfield Armory. In 1825, Blanchard also invented America's first car, which he called a "horseless carriage," powered by steam. During Blanchard's lifetime, he was awarded over twenty-five patents for his creations.
Biography.
Tacks.
He was born in Sutton, Massachusetts. He had a fondness for mechanical employment, and was associated with his brother in the manufacture of tacks by hand. This process was exceedingly slow and tedious, and his first machine, made and patented in 1806, was a mechanical tack-maker, which could fabricate five hundred tacks per minute, each much better than tacks made by hand. He sold the rights to his machine for $5,000.
Machine tools for gun making and pattern copying lathe.
Blanchard then turned his attention to gun barrels, and invented a machine tool that streamlined the process of their manufacture. Hired by the Springfield Armory during its construction, Blanchard finished the machine in 1822. The machine turned and finished gun barrels in a single operation; the octagon portion of the barrel was finished by changing the action of the lathe to vibratory motion. This invention was afterward extended to the turning of all kinds of irregular forms.
He also developed a copying lathe that traced a model to turn gun stocks, producing the desired contour automatically (1818). The copying lathe began being used to make shoe lasts (forms) in the 1850s. By being able to accurately reproduce lasts it was possible to make shoes in standard sizes.
Steam transportation.
Turning his attention to transportation, Blanchard invented a "steam wagon" before the introduction of railroads in the United States, and in 1831 created a powerful upriver steamboat that was used on the Connecticut River and the West, both of which he invented and patented in Springfield, Massachusetts. In 1851, he designed and created a machine that could bend dense and strong wood.
Blanchard also constructed machines for cutting and folding envelopes at a single operation, and several mortising machines.
