Improvements in Motor-driving Arrangements for Lathes

7055. Barrow, J. April 4. Lathes.-In order that the spindle and the first and other motion shafts of a lathe may be easily accessible for the adjustment of their bearings or for their removal, the electric driving-motor F is arranged at the rear of the lathe, being carried on a stool formed on or bolted to the headstock base P, or arranged on an extended transverse shaft C, to which it is connected by a flanged coupling. This shaft passes beneath the lathe spindle D, and to admit of endways movement, it is provided with a pinion G narrower in face than the pinion H on the shaft J with which it meshes. Both shafts are carried in bearings formed by a bracket N bolted to the standard 0 and to the caps Q, R, the other end of the shaft J being carried in a similar bearing secured to a similar pedestal T and having a cap U, while the usual shaft S is carried in an aperture in the bracket. The bevel pinion on the shaft J gears with a bevel-wheel on the shaft M, on which also is a pinion V meshing with the wheel B on the faceplate or chuck A. The speed may be varied by the use of pinions upon the shafts M, S.
