Protractor for calculating miter and bevel angles for installing molding
First Claim
Patent Images
1. 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.

Abstract
Taught herein is a protractor capable of measuring angles within a room and angles related to the intended orientation of molding with respect to the room. Using these angles, the present invention will calculate and display the appropriate angles at which a miter saw must be set to produce mitered joints for the installation of trim and crown molding.
