Universal geometrical measuring instrument
Abstract
Abstract A UNIVERSAL GEOMETRICAL MEASURING INSTRUMENT OF THE BEAM-TRAMMEL TYPE ADAPTABLE TO FORM OPPOSED CONTACT SURFACES OF VARIOUS CONFIGURATIONS TO INDICATE DIMENSIONAL DISTANCES BETWEEN SIMILAR OPPOSED SURFACES OF A VARIETY OF CONFIGURATIONS FORMED ON A WORKPIECE TO BE MEASURED. THE MEASURING INSTRUMENT INCLUDES A SCALE OR BEAM HAVING A PAIR OF TRAMMEL BLOCKS RELEASABLY SECURED THERETO AND SLIDABLE THEREALONG. EACH TRAMMEL BLOCK INCLUDES MEANS FORMING AT LEAST A PAIR OF APERTURES, WITH ONE APERTURE OF THE PAIR DISPOSED NORMAL TO THE OTHER APERTURE, AND MEANS ENGAGEABLE WITH THE APERTURES FORMING CONTACT SURFACES, INDICATING POINTS AND SCRIBES TO MEASURE DIMENSIONAL DISTANCES OF SURFACES HAVING A VARIETY OF CONFIGURATIONS, FOR EXAMPLE CYLINDRICAL SURFACES, UNDERCUT GROOVE PORTIONS, THREADS, SLOTS AND PARALLEL SURFACES. ALSO, MEANS ARE PROVIDED FOR CLAMPING TWO OR MORE SCALES IN A SERIES ARRANGEMENT TO PROVIDE AN EXTENDED SCALE TO FACILITATE MEASURING EXCEPTIONALLY LARGE WORKPIECES.
