Description: |
| Abstract:
The end in view in this invention is to so construct a micrometer gage that the index sleeve may be comparatively short say one inch long, more or less and be used to indicate correctly on a gage of any desired size and length of screw, and it consists in making the screw movable and adjustable in the sleeve.
Claim:
A micrometer-gage having, in combination, a frame, A, provided with a graduated fixed screw-nut, E, a revolving measuring-screw, B, and a graduated sleeve, D, said sleeve being shorter than the measuring capacity of the gage, and arranged to be changed and fastened to different parts of the screw and pass to and fro over the screw-nut E.
