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.
