ABSTRACT:
A tool joint caliper and identifier particularly adapted for use in making up a drill string employed in an oil well drilling operation. The caliper and identifier includes a pair of pivotally connected caliper arms having contact points at an end thereof remote from the pivotal connection for engagement with a pin tool joint or a box tool joint. The other end of each of the arms includes an extension with one extension being in the form of a panel having concentrically spaced arcuate graduated scales thereon together with associated indicia and the other extension includes a pointer having a radially inwardly extending point and a radially outwardly extending point associated with the graduated scales for indicating the diameter of the tool joint and identifying the tool joint engaged by the contact points. Each graduated scale includes two circumferentially spaced arcuate scales with one set of arcuate scales measuring the external diameter of a pin tool joint and identifying the pin tool joint and the other set of arcuate scales measuring the internal diameter of a box tool joint and identifying the box tool joint. The extension having the graduated scales and indicia thereon also includes thread measuring gauges which combined with the caliper and identifier facilitate the making up of a drill string.
