Abstract

26,977. Spencer, C. M. Nov. 23. Lathes.-The work - t u r r e t spindles of a multiple-spindle screw-machine are driven, as shown in Fig. 1, by single helical gearing from the central spindle in such manner that the thrust of the tools is balanced by the end thrust due to the gearing and transmitted to a thrust bearing on the central spindle.
