摘要：A measuring instrument for measuring the distance from a hole, drilled at theintersection of a rib and a stringer, to the adjacent flange of the rib includes two armsprojecting laterally out from the side of the instrument and forward to engage theflange. The arms are geared together at their inner ends within the body of the
instrument to insure that the angles of both arms relative to the longitudinal axis of thebody are equal to each other so that the longitudinal axis of the instrument in useremains perpendicular to the face of the flange. A spring loaded conical hole-centeringprobe protruding from the bottom face of the instrument fits into and centers itself inthe hole and establishes a reference from which the flange is measured. A stylus, slidablymounted in the instrument and protruding from the front end thereof, contacts the faceof the flange. A linear measuring gauge measures the position of the stylus in theinstrument to provide an accurate measure of the distance of the flange to the hole in adirection perpendicular to the flange.
