728,898. Shoots. LIPE-ROLLWAY CORPORATION. July 31, 1951, No. 18085/51. Class 78 (1). [Also in Group XXII] Means for delivering stock bars B to the hollow spindle of an automatic lathe (see Group XXII), comprise a transversely movable trough 12 which is intermittently positioned below a shoot 14 to receive a new bar. As the trough is moved, a rack bar 45, attached thereto, turns a spindle 50 carrying an elongated pinion 50A engaged by rock-bars 43, 44. The bars 43, 44 serve to release the bars singly. The trough is moved automatically by a pneumatic piston 40. The machine may be controlled pneumatically, hydraulically or electrically.
