Abstract

21,308. Crell, O. Sept. 17. Turning nuts. - A four-spindle work-turret hollow-spindle lathe for turning nuts from bar stock is arranged to produce four nuts for each rotation of the turret. Stock is fed twice during such rotation, and the feed and chuck members are operated by interconnected levers from the cam shaft. At position 1, Fig. 2, stock is fed against a stop 40, pivoted at 41 and cam-operated at 42. A facing-tool 51 and parting-tool 57 for position 2 are carried by a cross-slide and corresponding tools for positions 3 and 4 are carried by the slide 46 operated by a cam lever with adjustable fulcrum 56. Parting-tools for positions 1 and 3 are carried by a lever rest pivoted about the axis of the turret and cam-operated at 67. The stop 44 for position 3 is pivoted at 45 and adjustably connected at 48 to the slide 46. The lathe may be arranged to produce more intricate work by disconnecting the feed or like mechanism for position 3 and by replacing the parting-tools 57, 59, 60 and the stop 44 by other tools.
