Abstract

915,282. Automatic lathes. BECHLER, A. March 21, 1961 [April 6, 1960], No. 10259/61. Class 83 (3). Automatic lathe work-transfer mechanism is arranged for feeding partly-finished workpieces 33, Fig. 1, from a channel member 26 to an automatic lathe chuck 3, Fig. 4. The lathe headstock 1 is provided with a pivoted transfer arm 8 which is moved by rack and lever mechanism 12a, 12, respectively, from a cam 11 on the main cam-shaft 10. An adjacent cam 16 moves the transfer arm axially along its pivot 5 through levers 17, 19. The channel member 26 is hand-loaded and the workpieces are spaced apart by fingers 28 on a bar 27 which may be oscillated by the transfer arm to disengage the workpieces. When the transfer arm is in position to pick up a new workpiece it is moved to the right, Fig. 1, so that a set-screw 32a pushes on the end of the channel member and slides it along against a spring 31. The workpiece is picked up in the end of the arm and the transfer arm rotates a small amount away from the lathe spindle (broken lines, Fig. 4) so that a lug 8d on the transfer arm engages a screw 30 on a part 29 of the bar 27 to rock it and free the workpieces from fingers 28. The transfer arm and channel member now move to the left, Fig. 1, bringing a new workpiece into position for the next transfer operation.
