ABSTRACT:
An air gage (10) is provided for measuring an otherwise inaccessible right angle opening (12) in a confined spaced in a workpiece (14). An air plug (18) extends axially into the opening (12) and has a central air passage (22) communicating with one or more transverse air passages (24 and 26) directing air outwardly of the plug (18) and against the workpiece (14) in the opening (12). A collar (40) mounted to the plug (18) has an air passage (60) therethrough communicating with the central air passage (22) in the plug (18). The collar (40) has a generally cylindrical cavity (50) forming a socket with an arcuate opening (74) in a cylindrical sidewall (66) subtending a given arc. An extension arm (36) has an inner cylindrical end (52) received in the cylindrical cavity (50), and has a tubular rod (76) extending from the inner cylindrical end (52) outwardly through the arcuate opening (74) in the cylindrical sidewall (66) and movable along the noted arc to articulate and pivot the extension arm (36) by pivoting the inner cylindrical end (52) in the cavity (50) about a pivot axis (42) along the cylindrical axis of the cavity (50), which axis (42) is perpendicular to the axis (20) of axial extension of the plug (18). The extension arm (36) has an internal air passage (38, 78, 64, 62) through the tubular rod (76) and the inner cylindrical end (52) communicating with the air passage (60) in the collar (40). The degree of articulation of the extension arm (36) is determined by the arc subtended by the arcuate opening (74) in the collar (40), which articulation facilitates access to otherwise inaccessible openings in workpieces.
