Abstract
An instrument for the measurement and verification of linear dimensions includes a body equipped with external and internal feelers, a perch mounted in a slideway in the body and equipped with external and internal feelers cooperating with those of the body, and independent depth gauge mounted in a second slideway of the body, and a feeler rod mounted in a third slideway of the body, and cooperating with a contact piece fastened with an inner face of the external feeler of the perch. A movable member of a measurement transducer is selectively connected to the perch, to the gauge and to the feeler rod by a selective coupling device. In turn, a display device with zeroing control is connected to the measurement transducer. In a single apparatus, the subject instrument is capable of measuring and verifying different linear dimensions, such as for instance, the diameter of a shaft, the depth of a blind hole, the length of a shaft or groove, or any reduction of a diameter of a finished part or a part in the course of manufacturing.
