488,280	Dec. 20, 1892	Micrometer Gage	Joseph P. Lavigne	New Haven, CT	Earle & Seymour - patent attorneys Joseph P. Lavigne owned the Lavigne Micrometer Co. of New Haven, CT. This invention relates to an improvement in that class of calipers or gages which are adapted to be set or to measure with the greatest accuracy, and commonly called "micrometer gages" or "calipers," the object of the invention being to adapt the gage to be readily adjusted to units of measurement, but with positive accuracy.
488,281	Dec. 20, 1892	Micrometer Gage	Joseph P. Lavigne	New Haven, CT	This invention relates to an improvement in that class of gages of caliper-like character which are adapted to close and accurate measurement, commonly called "micrometer gages," and particularly to that class in which a longitudinal screw-spindle having a predetermined thread, say forty to the inch is arranged in bearings so that by rotation it will be moved longitudinally according to the extent of its thread toward and from a fixed point in the same gage, and so that an article placed between the end of the screw-spindle and the said fixed point, the screw-spindle may be moved up to the opposite side of the said article, and there brought to a stand, the space between the end of the screw-spindle and the said fixed point will correspond to the distance between the two bearing points on the article so standing between the end of the screw-spindle and the said fixed point. Combined with the screw-spindle of a predetermined thread, a stationary scale is arranged, graduated longitudinally according to the thread of the screw-spindle, and upon the screw is a rotating head, which running along said scale serves as an indicator on the scale, and this head being cylindrical, has a predetermined graduation upon its periphery, say divisions of twenty-fifths, which graduations in connection with said scale will indicate in thousandths the exact distance between the point of the screw-spindle and the fixed point in the gage. This is a common and well known construction of gage. Gages of this character are usually made with but a single space for measurement, consequently if the screw-spindle happen to be withdrawn to the fullest extent so as to make that space its maximum length, and the measurement required is much less than that space, then the screw-spindle must be run toward the fixed point accordingly, and vice-versa. For illustration, if the gage be adapted for two inch measurement, and the screw-spindle be near the open extreme, and the length to be measured is less than one inch, then the movement of the screw-spindle must be one fall inch plus the extent of movement to bring it to a bearing upon the article to be measured within the next inch. Again, if the gage be closed, that is the end of the screw-spindle against the fixed point of the gage, and more than one inch is required, then the longitudinal movement of the screw-spindle must be made one full inch plus the additional movement required for the gage to embrace the article. The object of this invention is to combine in one gage two spaces within one of which one end of the screw-spindle will operate, and in the other space the other end of the screw spindle will operate, one space being twice as great as the other, and so that should the article to be gaged be greater than that of the smaller space, the measurement may be made in the broader space with but a slight longitudinal movement of the screw-spindle, and vice-versa, and by which in many cases a very much less longitudinal movement of the screw So will be required than in the usual construction of this class of micrometer-gages, and which have but a single measuring space, and in such a gage the invention consists. In the illustration a gage is shown in which the two spaces for convenience are made the one to represent one inch opening and the other two inches.
508,952	Nov. 21, 1893	Micrometer Gage	Joseph P. Lavigne	New Haven, CT	Joseph P. Lavigne owned the Lavigne Micrometer Co. of New Haven, CT. My invention relates to an improvement in that class of micrometer gages in which the measuring of inches is done by a set of movable pieces differentiated in length by inches, and adapted to be interchanged with each other, and in which the measuring of fractions of inches is done by a measuring-screw, the object being to produce a simple, convenient and durable instrument having its movable pieces applied to the outside of its beam. With these ends in view my invention consists in a micrometer gage having a movable jaw and a fixed jaw, means for measuring fractions of inches, and a series of measuring sleeves differentiated in length by inches, and adapted to be interchanged with each other to determine the position of the movable jaw with respect to the fixed jaw.
510,688	Dec. 12, 1893	Micrometer Gage	Joseph P. Lavigne	New Haven, CT	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.
