Description: |
| "This invention relates to surface indicators and more especially to that class thereof which are employed to determine the 'true-running' condition of a piece of work in a lathe, grinding machine, or other machine tool, in order to enable the workman to center the same properly, or to determine its eccentricity or deviation from a true circular on the line of its contact with its device. My invention has for one of its objects the provision of an instrument of this class which may be secured in a tool-post of a lathe, and the working parts of which are normally protected by being contained within the interior of the stem of the device..."The inventor would go on to co-found the Brink & Cotton Mfg. Co., of Bridge which made vises and clamps among its products. |
