Abstract

486,332. Lathes. WICKMAN. A. C. Jan. 28, 1937, No. 2486. [Class 83 (iii)] A lathe headstock comprises the combination of a spindle a, which is both rotatable and axially slidable and is adapted to carry the workpiece, another rotatable and axially slidable spindle i, having a screw-thread or equivalent connection with a normally stationary part w of the headstock, a undirectional clutch x for transmitting' rotary motion from the second to the first spindle, means for transmitting axial motion from the second to the first spindle, means for driving the second spindle at a rate appropriate to a thread-milling operation and means for driving the first spindle at a rate appropriate to a normal turning operation. A driving shaft e transmits motion either to a belt-pulley d or to a shaft n through bevel wheels q, p, according to the position of a hand lever t operating simultaneously clutches g, h, and r, s. The belt pulley d drives the spindle a for normal turning operations while the shaft n drives, through worm gearing m, the spindle i at a much slower speed, the shaft n may also be rotated by a, handwheel o. The spindles i and a are connected together for axial movement by the thrust bearings 3 and with the drive to the spindle i engaged the threaded portion v keyed thereto rotates in the nut w, which is held stationary, and the axial movement necessary for a thread milling operation takes place. The nut w may be rotated to adjust the axial position of the spindles prior to a working operation. The apparatus is described as applicable to performing a, facing operation on the end of the nose of a shell and screw thread milling the interior of the nose.
