ABSTRACT:
A measuring tool for use particularly in carpentry combines the features of a square, a level and a bevel tool into a single device. The measuring tool includes a clevis-like handle which supports a slide rule at one end, and a pitch slide which can be adjustably positioned within the handle for limiting pivotal movement of the slide rule with respect to the handle. The angular orientation of the slide rule can be fixed with respect to the handle when the slide rule is engaged by the pitch slide, and a carriage bolt is tightened to squeeze the slide rule between a pair of handle bracket members. Several linear and angular measurement scales are provided the slide rule, and a level vial is attached to the handle.
