Description:

Claim:

This invention relates in general to machine tools and in particular to means for indicating precisely the positions of machine tool elements which are movable in opposite directions. While the invention will find advantageous application on a variety of machine tools, it is especially useful with very large machines which previously presented difficulties and inconvenience to an operator in observing the movable part he was positioning while staying in touch with his controls and position indicating dials.
