a tool for gauging the height of some point on a piece of work, above a surface plate or machine table; it consists of a base supporting a pivoted column, to which a scriber is slidably clamped

This device is used to lay out lines at a set of height from the base for testing the accuracy of plane surfaces drawing a horizontal line directly on the object at any height.
