Thomas BlanchardDied 16 Apr 1864 at age 75 (born 24 Jun 1788).American inventor who made major contributions to the development of machine tools. He invented a number of machines before he created the famous lathe that bears his name. At age 13, he developing an apple-paring machine. While employed by his brother in the monotonous job of making tacks, which all had to be headed by hand, Blanchard came up with a machine for mass-producting the tacks. He went into the armory business, for which he developed a specialized lathe which could turn irregularly shaped parts, such as gunstocks. Blanchard's profile lathe also revolutionized other industries that manufactured standardized, asymmetrical items, such as axe handles, shoe lasts, and wheel-spokes. |
