ABSTRACT:
An indicating instrument, particularly for indicating small displacements of a feeler for use in locating the precise position of notches in a program strip to set up a machine tool. The instrument has a lever arm fixed with respect to the feeler and an abutment member moved by the lever arm to give mechanical movement magnification, the degree of magnification being different for different ranges of movement so that the instrument is most sensitive at a predetermined zone of feeler movement, thereby allowing a condensed indicator scale.
