Abstract

538,430. Turning. SCHWOB, T. Oct. 30, 1939, No. 29007. [Class 83 (iii)] In an automatic lathe the cam shaft controlling the feed of the tools rotates at a constant speed and auxiliary cam shafts rotate intermittently to effect the idle movements at a high speed. The spindle 213 is geared as indicated to a motor 201 geared at 214 to a countershaft 31 that drives the feed cam shaft 15 through spur and worm gearing 217, 221, and drives the auxiliary cam shafts 27<SP>1</SP> and 224 through constantly running clutch parts 261, 26. When an idle movement of the tools, or rotation of the turret, stock feed &c. is to be effected, a tappet wheel 40, Fig. 2, on the shaft 15, by means such as a lever 371 trips a dog 361 allowing a spring 331 to shift the clutch part 25<SP>1</SP> (or 25) into engaged position. At the end of the idle movement the surface 351 causes the clutch to disengage position and a spring block 431 acting on a cam 44<SP>1</SP> brakes the movement. Specifications 537,470, 538,431 and 538,432 are referred to.
