Patent ID: 6918189

Claim:
A combination layout tool comprising a triangular shaped member having three side edges that intersect at opposite ends to form three angle corners, one of said side edges extending between two of said corners having a notch in said one side edge that is closer to one of said two corners than the other of said two corners, and a plurality of laterally spaced apart elongated incremental angle slots in said member adjacent the side edge of said member opposite said one corner that extend in a direction in radial alignment with said notch in said one side edge, said member having two 67½° angle corners and one 45° angle corner, said one side edge extending between said 45° angle corner and one of said 67½° angle corners, and said notch in said one side edge being closer to said one 67½° angle corner than the intersection of a line extending perpendicular from the other of said 67½° angle corners with said one side edge.
