Blanchard lathe
(gcide) | 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.
