Embodiment Construction

[0031] For a better understanding of the invention and its operation, turning now to the drawings, FIG. 1 demonstrates preferred measuring device 10 seen in perspective fashion having base 11, level 12 and protractor 13. As shown in FIGS. 1, 2, and 7, slot 24 is defined by level 12 to accommodate protractor 13. Protractor 13 is rigidly mounted within base 11 such as by pins, frictionally fitting therein or with conventional glues or adhesives. Level 12 is also mounted to base 11 by hinge 15. Window 16 within level 12 is preferably formed from a transparent rigid plastic material such as a clear polycarbonate or polyacrylate and is affixed to level 12 as seen in FIGS. 1, 3, and 4. Window 16 includes aperture 17 through which threaded locking member 18 is positioned. Locking member 18 passes through window aperture 17 of window 16 and slot 19 of protractor 13 whereby, effectively bolt nut 14, as seen in FIG. 2, is used to tighten threaded member 18 in place. Locking member 18 can be m...

Abstract

A measuring device is provided for carpenters, roofers and other tradesmen. The device is made of relatively lightweight plastic and has a variety of uses. The elongated base is rectangular in cross-section and includes a scale for measuring distances along one side. Pivotally affixed to the base is a level which can be locked against a protractor (also affixed to the base) at any angle between zero and ninety degrees (0°-90°). Roof pitches, gradients and other angles can be determined or set in a simple, easy to learn manner. In addition, a guide is provided which can be releasably attached to the measuring device for use in combination therewith for precise repeated markings on lumber pieces or boards for forming stair stringers and the like.
