Description: |
| Earle & Seymour - patent attorneys
Joseph P. Lavigne owned the Lavigne Micrometer Co. of New Haven, CT.
My invention relates to an improved micrometer gage, adapted for inside as well as for outside measuring, of the type of instrument in which the measuring of inches is done by a set of movable gages, differentiated in length by inches, and the measuring of fractions of inches by a screw, the object being to produce a simple, convenient and durable instrument, operating with a very high degree of precision, and covering a wide range of measuring work. With these ends in view, my invention consists in the combination, in a micrometer gage, with the beam thereof, of mechanism applied thereto and located partly within the same for measuring fractions of inches, and two measuring jaws, one of which is connected within the beam with the said mechanism, and adjusted on the beam thereby, the outer ends of the said jaws being constructed and adapted for inside and outside measurements, being thereto made narrow, and carrying in themselves no measuring mechanism. My invention further consists in the combination with such a device as described, of movable gages, differentiated in length by inches, and applied to the beam of the instrument so as to determine the position of the other jaw thereof thereon in accordance with their relative arrangement.
