Abstract

Angular displacement indicia marks are imprinted on each section at its juncture with an adjoining section to visually indicate the degree of angular displacement between adjacent sections.
Claims6
A level/protractor tool comprising a first section, said first section housing a first spirit vial means for providing a visual indication of a level plane relative to a reference surface, and a second section pivotally connected to said first section for relative angular displacement therebetween, said second section housing a second spirit vial means for providing visual indication of a level plane relative to a reference surface, indicia marks imprinted on said first and second sections for providing a visual indication of angular displacement between said first and second sections, said first section including a frame portion and an integral cross member positioned substantially perpendicular to said frame portion, said cross member housing a third spirit vial means positioned at substantially a right angle relative to said first and second spirit vial means, said third spirit vial means for providing a visual indication of a level plane relative to a reference surface, said frame portion pivotally connected to said second section by a pivot pin.
