Of thiskind is A, in which the piece a to becut is moved longitudinally throughthe holder h, and at the same time isrotated so that the tool c in its revolu-tions may cut the spiral groove shownat a. 679. B is a fluting lathe in whicha pair of cutters revolve in a planeoblique with the line of motion of thebaluster. The latter is moved longi-tudinally by the rack and pinion e g,and rotated by the wheel and piniorhi; the cutters m m rotating in par-allel planes cut two grooves at MOTION AND CONTROLLING DEVICES, ETC. 257
