Abstract: An automatic gage measuring machine comprises a carrousel ring for storing and delivering standard gages and gages to be tested and comprising a flat circular ring mounted for rotation about a vertical axis. The carrousel ring is driven intermittently. The gages are measured by at a measuring station including two sensing members having probes movable along a vertical axis for contact with opposed sides of a gage. A pair of gages are transferred from the carrousel ring to the measuring axis on a gage support plate by first and second carriages mounted for movement in mutually perpendicular directions. A microprocessor synchronizes and controls movements of the various moving parts, controls the sensing members and stores the measurements.
