Description: |
| Joseph P. Lavigne owned the Lavigne Micrometer Co. of New Haven, CT.
My invention consists of a micrometer gage having a beam and two measuring jaws, one of which is movable, and two or more movable measuring pieces differentiated in length, adapted to be applied to the exterior of the beam, and cooperating with the said movable jaw to determine the position thereof with respect to the other jaw. My invention further consists in a micrometer gage having a longitudinally grooved beam, furnished at one end with a fixed jaw, a movable jaw mounted on the said beam, means for measuring fractions of inches carried by the said movable jaw, and a series of movable measuring pieces adapted to fit into the groove in the beam, differentiated in length by inches, and designed to be interchanged to determine the separation of the fixed and movable jaws.
