Abstract
20,681. Herbert, A., and Wright, I. H. Oct. 1. Feed-motions ; gearing, driving.-The slides of machine tools are actuated by gearing modified to prevent back-lash. A rack A is fixed to the toolslide, and a second rack C is connected to the slide by a spring D. A worm N gears with the two halves L, M of a worm-wheel, one half L being attached to a spindle K carrying a pinion H gearing with the rack A, and the other half M being attached to a sleeve J. To the sleeve J is fixed a pinion G gearing with a pinion F, which in turn gears with the rack C. The pinion F may be omitted. A spring R and thrust bearings P may be provided to prevent longitudinal slackness in the worm.
