Abstract
An angle measuring tool for us in combination with a standard framing square. A saddle protractor having a plurality of alignment tabs is engaged with a standard framing square by placing the saddle protractor in fact to face contact with the framing square and in alignment with the alignment tabs. Various incremental indicia on both sides of the saddle protractor depict angular measurements as measured from a pivot point on the saddle protractor. Other alignment tabs and pivot points on the saddle protractor also allow the saddle protractor to be used as a miter layout device to scribe various cutting angles on material having angular cuts.
Claims25
An angle measuring tool, comprising:
- a flat member having a top surface and a bottom surface, the flat member having the shape of a right triangle having a hypotenuse and two adjacent sides;
- a first plurality of marking indicia on the top surface;
- a second plurality of marking indicia on the bottom surface;
- a third plurality of marking indicia on the top surface;
- and
- a plurality of alignment tabs protruding upward from the top surface, the plurality of alignment tabs being generally perpendicular to the top surface, the plurality of alignment tabs also being spaced a distance apart such as to accommodate a standard framing square.
A method of measuring angles comprising the steps of:
- placing a framing square onto an angle measuring tool having a plurality of angular marking indicia and a plurality of alignment tabs to align the framing square with the angle measuring tool;
- and
- using the angle measuring tool in conjunction with the framing square to measure angles from one of either an apex of a right triangular corner of a triangular orifice within the angle measuring tool or a right triangular outside corner of the angle measuring tool.
An angle measuring tool, comprising:
- a right-triangular shaped flat member having a hypotenuse side, an exterior right triangle corner, and a flat surface;
- a right triangular orifice, the right triangular orifice having a hypotenuse side and an interior right triangle corner, the right triangle orifice being located within the interior of the angle measuring tool such that the hypotenuse side of the right triangular orifice is parallel to the hypotenuse side of the flat member and the right triangle orifice being centered on the flat member;
- means for measuring angles from about 0 degrees to about 90 degrees as measured from the exterior right triangle corner of the flat member;
- and
- means for measuring angles from about 0 degrees to about 90 degrees as measured from the interior right triangle corner of the right triangular orifice.
