Abstract
A right angle square includes a right isosceles triangle shaped right angle square with three sides. The three sides comprise a pitch edge, a hypotenuse, and another side. The right angle square also has a closed and arced angular measurement tube extending along a portion of a circumferential arc between the non-hypotenuse sides and the tube contains a fluid and a bubble that moved through the fluid. The right angle square also has a measurement scale. When the pitch edge is aligned against a slope to be measured, the bubble rises to the highest point in the tube, and the bubble is aligned on the measurement scale at a point along the measurement scale corresponding to the slope being measured.
Claims20
A right angle square comprising:
- a right isosceles triangle shaped speed square comprising three sides, the three sides comprising a pitch edge side, a hypotenuse side, and another side;
- a closed and arced angular measurement tube extending along a portion of a circumferential arc between the non-hypotenuse sides, the tube containing a fluid and a bubble that moved through the fluid;
- a tube measurement scale that measures a slope;
- and
- a pitch wheel comprising a rotatable outer wheel and a rotatable inner wheel comprising a bubble level, wherein when any edge is aligned against a slope to be measured and the tube level is set to its level point, an arrow on one of the wheels aligns with a wheel measurement scale on the other one of the wheels corresponding to the slope being measured;
- wherein when the pitch edge is aligned against the slope to be measured, the bubble rises to a highest point in the tube, and the bubble is aligned on the tube measurement scale at a point along the tube measurement scale corresponding to the slope being measured.
A right angle square comprising:
- a right isosceles triangle shaped speed square comprising three sides, the three sides comprising a pitch edge side, a hypotenuse side, and another side;
- a pitch wheel comprising:
- a rotatable inner wheel comprising a tube level;
- and
- a rotatable outer wheel comprising a wheel measurement scale for measuring a slope;
- wherein when any edge is aligned against a slope to be measured and the tube level is set to its level point, an arrow on one of the wheels aligns with a measurement on the wheel measurement scale corresponding to the slope being measured, wherein the wheels rotate about a common center point.
