Patent ID: 7574813

Claim:
A protractor for assistance in miter and bevel angle calculations for joining molding comprising: two arms, each having a longitudinal axis, a proximal end, and a distal end, joined by a pivot means at their proximal ends and each having a means of attaching a specimen of molding at their distal ends; wherein the pivot means has a means of measuring the angle between the two arms; wherein each arm has a means of rotating about its longitudinal axis to change each arm's angular relation between its respective proximal and distal ends; wherein the means of rotating has a means of measuring the angular relation; wherein the means of measuring the angle between the two arms and the means of measuring the angular relation are in communication with a logic unit; and wherein the logic unit is in communication with a display means that communicates the protractor's measurements and miter and bevel angle calculations to a user of the protractor.
