Standardized arched jamb assembly and method

A method for constructing an arched jamb assembly, said method comprising the steps of:

• (a) making an angled end cut at each of a pair of opposite ends of an arched jamb member such that an apex is formed by the angled cut that protrudes outwardly from the respective one of the opposite ends of the arched jamb member;
• (b) making an angled notch cut in an inner corner of each of the upper end portions of a pair of upright jamb members such that the angular configurations of the angled end cuts and angled notch cuts are substantially the same;
• and
• (c) placing the arched jamb member on the upper end portions of the upright jamb members such that the angled end cuts of the arched jamb member meet and interface with the angled notch cuts of the upright jamb members so as to assemble the arched jamb member with the upright jamb members to form an arched jamb assembly for defining a wall opening.

A standardized arched jamb assembly for framing a wall opening, comprising:

• an arched jamb member having a pair of opposite ends and first angled 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, a curved upper face and a curved lower face of predetermined curvature and radius of curvature, the arched jamb member being of predetermined width between said front and rear faces;
• a pair of opposite upright jamb members for installing on opposite sides of the wall opening, the upright jamb members having an inner face, opposite front and rear faces and being of predetermined width between said front and rear faces substantially matching the width of the arched jamb member, each upright jamb member having an upper end portion 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 for framing a wall opening, such that the opposite front and rear faces of said arched jamb member are substantially flush with the opposite front and rear faces of said upright jamb members;
• and
• said first angled cuts of said arched jamb member for interfacing with said second angled cuts of said upright jamb members and said second angled cuts of said upright jamb members each being comprised of 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.

A method of making an arched jamb assembly, comprising the steps of:

• making a first angled end cut at each of a pair of opposite ends of an arched jamb member, each first angled end cut having only three perpendicular sides formed in a single cutting step, the three perpendicular sides comprising a first, generally vertical side extending from an upper face of the arched jamb member, a second, generally horizontal side extending generally horizontally inwardly from the first side, and a third, generally vertical side extending from the second side;
• making a second angled notch cut at an inner corner of an upper end of each of a pair of upright jamb members, the angled notch cut having only two perpendicular sides and the angular configuration of the angled notch cut being substantially the same as the angular configuration of the first and second sides of the first angled end cut;
• placing the upright jamb members at opposite sides of a wall opening such that the second angled notch cuts face inwardly and towards one another;
• placing the arched jamb member to extend between the upper ends of the upright jamb members with the first and second sides of the angled end cuts of the arched jamb member engaging and interfacing with the angled notch cuts of the upright jamb members and the third side of each angled end cut acting as a stop against an inner face of the respective upright jamb member.
