ABSTRACT:
By mounting a longitudinally extending blade with a mounting block for pivotal movement about an axis perpendicular to the longitudinal axis of the blade, in combination with a distance measuring meter mounted to measuring engagement with the movable blade, a precision squareness measuring gauge assembly is achieved for providing highly accurate measurements of the angular relationship of one surface to a reference surface. In the preferred embodiment, the precision measuring gauge assembly also incorporates pivot limiting means for controlling the arcuate distance through which the blade is able to pivot. In this way, the entire arcuate travel distance of the blade is accurately measured and displayed on the meter, thereby providing a direct accurate measurement of any desired surfaces.
