Blanchard lathe \Blan"chard lathe\ [After Thomas Blanchard,
   American inventor.] (Mach.)
   A kind of wood-turning lathe for making noncircular and
   irregular forms, as felloes, gun stocks, lasts, spokes, etc.,
   after a given pattern. The pattern and work rotate on
   parallel spindles in the same direction with the same speed,
   and the work is shaped by a rapidly rotating cutter whose
   position is varied by the pattern acting as a cam upon a
   follower wheel traversing slowly along the pattern.
