Abstract

A device for checking dimensions of machine parts or the like, consisting of a dual inter-dependent keyed linear structures having inter-connected operating elements to maintain the unique multiple gage stack feature of my U.S. Pat. No. 3,180,029 with the use of much smaller gage blocks, to accommodate an extra large micrometer thimble graduated about its circumference to one hundred thousandths in ten thousandths of an inch, permitting when the micrometer screw thread is 10 threads to an inch to obtain a reading within one turn of the thimble when the one hundred thousandths gage blocks are utilized and within ten turns when the one inch gage blocks are used. A scriber setting mechanism is incorporated to allow the setting of a scriber, that is secured in a standard height gage, to a required height by utilizing the spring loaded scriber setting arms instead of the spring loaded dial indicator point that would be held in another standard height gage. Although the gage stack and scriber setting unit is extended the micrometer thimble remains within easy reach for comfortable manipulation.
