Abstract
281,202. Borel, M. A., (Assignee of Challet, E.). June 11, 1927, [Convention date]. Linear - dimension gauges: - Comprises a method of trueing the measuring jaws of sliding calliper gauges having four jaws, b<1> b<2>, c<1> c<1> and consists in providing a centering hole d<1> d<2> at each end of the bar a the axes of these holes being on a line parallel to or coinciding with the axis of the bar, centering the callipers on these holes in a grinding machine and grinding up the first pair of jaws, then turning the callipers through 180‹ and grinding up the second pair of jaws.
