ABSTRACT:
An instrument can simultaneous measure a diameter of and a lateral distance along a workpiece. The instrument employs a first member having a longitudinal axis. The instrument also has a pincer device mounted on the first member to reciprocate along the longitudinal axis. This pincer device has a pair of arms mounted in a pincer-like fashion to enable measuring the diameter and the lateral distance along the workpiece. Also included is measurement system having a first and second mechanism. The first mechanism is coupled to the pincer device for providing in response to lateral translation of the pincer device relative to the first member a first readout corresponding to the lateral distance along the workpiece. The second mechanism is coupled to the pincer device for providing in response to angular displacement of the arms, a second readout corresponding to the diameter of a portion of the workpiece.
