The subject of this invention is a gage for taking accurate internal measurements. The invention relates, first, to constructing a micrometer-gage with a handle or holding pieces of wood or other material which is a poor conductor of heat, so that the heat from the hand may not be communicated to the metal of which the gage is composed; and, further, to connecting the handle or holding-pieces to the body of the gage by pins or fastenings of a material non-conductive of heat, as hereinafter explained. The invention further relates to means for adjusting the nut or screw socket on the micrometer-screw, so as to adapt the latter to work and measure with great accuracy, and to take up or compensate for any wear between the parts; also, to provisions for readily fixing the gage at any measurement to which it may be set. To these ends I construct the screw socket with a transverse slit extending on both sides of the micrometer-screw, and the set screws by which the screw-socket is adjusted to the said micrometer-Screw, and I provide, in addition to said set-screws, by which the parts are-kept in the required adjustment to adapt them to work accurately together, a locking screw, by which, without interfering with the set-screws, the nut or screw-socket may, when desired, be clamped upon the micrometer-screw, so as to lock the same and prevent its motion, and thus retain the gage at any adjustment to which it may be set. The invention further relates to the provision of screw-legs of different lengths, constituting the measuring-foot of the gage, interchangeable and adjustable for the purpose of accurately setting the instrument at a determinate gage length while the micrometer-screw is at zero, and in connection therewith set-screws for fixing the said adjustable foot-screws at the required adjustment. |
