Description: |
| This invention refers to measuring-gages of the kind in which one of two parallel measuring-legs is attached to a flat bar and the other to a slide adapted to be displaced along said bar. My improvements in measuring-gages of said kind relate to the means for securing the slide in position, and consist in letting the guide-flanges of the slide or suitable portions of said flanges project over the rear side of the flat bar and in connecting said flanges or portions by a screw or screwed spindle and nut in such a manner that the flanges of the slide may be drawn against and pressed upon the edge surfaces of the flat bar, so as thereby to secure the slide with its leg in position. The purpose of said improvements is to prevent said edge surfaces from being injured by the fastening-screw, as is the case in the measuring slide-gages at present employed, and to provide a somewhat extended pressing surface not on one side or edge only, but on both of them.
One of these calipers showed up on E-Bay from a seller in Germany. It was marked with the patent date and the word "Columbus". |
