Standardized arched jamb assembly and method

A standardized arched jamb assembly for defining a wall Opening, comprising:

• (a) an arched jamb member having a pair of opposite ends and angled end cuts made on said opposite ends, said arched jamb member also having opposite front and rear faces facing in opposite directions from a wall opening when installed in said opening, and having a predetermined curvature and radius of curvature, the arched jamb member having a curved upper edge and a curved lower edge and being of predetermined thickness between said front and rear faces;
• (b) a pair of opposite upright jamb members for installing on opposite sides of the wall opening, the upright jamb members having opposite front and rear faces and being of predetermined thickness substantially matching the thickness of the arched jamb member, and each upright jamb member having an upper end portion with an angled notch cut made therein at an inner corner of said upper end portion such that said angled notch cuts of said upright jamb members generally face toward one another and meet and interface with said angled end cuts on said opposite ends of said arched jamb member so as to assemble said arched jamb member with said upright jamb members to form an arched jamb assembly for framing a wall opening, such that the opposite faces of the arched jamb member are substantially flush with the opposite faces of the upright jamb members, said angled end cuts of said arched jamb member and said angled notch cuts of said upright jamb members have only two sides and are of substantially identical standard angular configurations irrespective of variations in the radius of curvature of said arched jamb member provided to define wall openings of different widths between said upright jamb members.

An arched wall opening assembly, comprising:

• a wall having opposite outer faces and an opening;
• the opening having an upper arched end and opposite sides;
• an arched jamb member extending across and defining the upper arched end of said wall opening, the arched jamb member having a pair of opposite ends and first angled cuts made on said opposite ends, said arched jamb member being of predetermined curvature and radius of curvature and having a curved upper edge and a curved lower edge;
• and
• a pair of opposite upright jamb members extending along and defining opposite sides of said wall opening, the upright jamb members having upper end portions and second angled cuts made at said upper end portions which meet and interface with said first angled cuts on said opposite ends of said arched jamb member so as to assemble said arched jamb member with said upright jamb members to form an arched jamb assembly defining said wall opening, said first and second angled cuts of said arched jamb member and upright jamb members being comprised of only two sides and having substantially identical standard angular configurations irrespective of variations in the radius of curvature of said arched jamb member provided to define wall openings of different widths between said upright jamb members.
