ABSTRACT:
This invention relates generally to mobile carpentry and drafting devices and, more particularly, to an integral combination type device which is capable of performing multiple geometry measuring functions within a single instrument. The invention relates specifically to a unique combination of independent carpentry functions into a single device to replace separate tools heretofore required to perform individual functions. The Squareangle may be used to check surfaces for plumb and levelness; check inside and outside squareness; find the center of a circle, square, or octagon; mark 45.degree. and right angles; scribe lines; measure distance; and perform other geometry and drafting functions without the aid of additional devices.
