ABSTRACT:
A machine tool dial assembly to enable readings indicative of the linear displacement of a machine element to be taken simultaneously in Metric and English units of measurement. The English dial is driven directly by the feed screw shaft and rotates in unison therewith. The Metric dial is mounted adjacent to and coaxially with the English dial and driven by means of the feed screw shaft through a gearing arrangement having an appropriate conversion ratio and comprising externally toothed driving and driven gears and a pinion gear in intermeshing engagement therewith. The dials are frictionally adjustable independently of the gearing arrangement and feed screw shaft by virtue of spring-biased friction shoes in contact with the inner surfaces of the dials.
