Metric Dial Device for Machine Tools

This modification of dial calibration provides a dual-measurement device that allows economical metric conversion for production machine tools of the type which normally require only setup adjustment settings.

The regular rotary dial element 10 carries inch graduations about the periphery, which are normally aligned with a stationary reference mark. To provide for metric adjustment, a disk 12 is fitted in a stationary position behind the rotary dial element 10 with radially posed metric divisions marked thereon in accordance with the lead screw pitch, as for example a segment may be adapted for a 1 or 2 millimeter advance.

In operation, the disk 12 remains stationary and to make metric adjustments, the advancement of a given inch graduation mark on dial element 10 is noted on the metric scale. The disk size and graduated segment may be adapted to all kinds of equipment.
