ABSTRACT:
Device for measuring an angle defined by two adjacent planes. The invention defines a pair of independent parallelogram units each hinged at their respective corners and each carrying an angle sensing unit at a first respective end thereof. The second respective ends of said parallelogram units are connected to an indicating device for responding to the relative position of said parallelogram units. One of the parallelogram units is secured to an angle sensing unit and an indicating device through spherical pivot bearings. Thus, the angle between said sensing units is reflected in and indicated by said indicator regardless of translational position changes between the two planes in the orthogonally related z and x directions.
