Abstract
A measuring device for measuring the arc of an arched window comprising a base; measuring means selectively rotatable relative said base for measuring a distance between said base and said arch at a selected angle.
Claims20
A measuring device for measuring the arc of an arched frame comprising:
- (a) a base having a substantially straight edge;
- (b) measuring means selectively rotatable relative said base for measuring a distance between said base and said arch at a selected angle;
- (c) bracing means slideable substantially parallel to said straight edge for bracing said base relative said arched frame.
A method of measuring an arch comprising:
- (a) releasably securing a base to an inside surface of said arch, said base including a measuring means rotatable relative said base;
- (b) sequentially rotatably displacing said measuring means relative said base for sequentially measuring a distance between said reference point and said arch at said selected positions.
A method of manufacturing a frame for an arched window comprising:
- (a) releasably securing a base to said arch, said base including a measuring means rotatable relative said base;
- (b) sequentially rotatably displacing said measuring means relative said base for sequentially measuring a distance between said reference point and said arch at said selected positions;
- (c) bending a frame to correspond to said measurements to form said arched frame;
- (d) placing said arched frame relative a template for verifying said arched frame.

A template for verifying the formed frame for an arch comprising:
- (a) a flat surface;
- (b) a plurality of radially extending members;
- (c) a plurality of scales associated with said plurality of radially extending members respectively;
- (d) a plurality of measurement recording members slideably securable relative said plurality of radially extending members said plurality of measurement members having an edge for displaying a measurement adjacent said scale, and for contacting said formed frame.
