Abstract
Abstract An arrangement for reducing the size of an opening on the bottom face of an evaporator cabinet adapted to be mounted on the top of a furnace, the filler arrangement comprising one or more channelshaped members which include one leg portion interengaging with a flanged border of the opening, a web which includes end portions overlapping the face of the wall containing the opening, and another leg portion including bendable tab means at the ends thereof bendable to a position to clear the opening for insertion, and then adapted to be bent back into their original planes for engagement with the distal edges of the flange means around the opening. The number of filler panels to be used in the arrangement is dictated by the reduction to be effected and may include one or two to reduce the length of the opening in increments, and an additional one or two extending transversely to the first two to reduce the width of the opening in increments.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
148 words
An insertable filler arrangement for reducing the size of a quadrilateral opening in a wall of a cabinet, the perimeter of the opening being framed by inwardly-directed flange means, said arrangement comprising: at least one filler panel of generally channel-shape in cross section and including a web and opposite edge legs; one of said legs including means for engaging distal edge portions of said framing flange means extending along one side of said opening; said web including end portions seating, upon installation of said filler plane, on the outer face of said wall on portions thereof bordering said opening along thE two sides of said opening adjacent said one side; the other of said legs including tab means at the opposite ends thereof movable, after insertion of said filler panel, to positions to engage distal edges of said framing flange means along said two sides of said opening.
Claim 2
Dependent Claim
148 words
An insertable filler arrangement for reducing the size of a quadrilateral opening in a wall of a cabinet, the perimeter of the opening being framed by inwardly-directed flange means, said arrangement comprising: at least one filler panel of generally channel-shape in cross section and including a web and opposite edge legs; one of said legs including means for engaging distal edge portions of said framing flange means extending along one side of said opening; said web including end portions seating, upon installation of said filler plane, on the outer face of said wall on portions thereof bordering said opening along thE two sides of said opening adjacent said one side; the other of said legs including tab means at the opposite ends thereof movable, after insertion of said filler panel, to positions to engage distal edges of said framing flange means along said two sides of said opening.
Claim 3
Dependent Claim
40 words
An arrangement according to claim 1 including: a second filler panel of the same construction a said one filler panel installed in said opening in mirror image relation to said one panel along the side thereof opposite said one side.
Claim 4
Dependent Claim
109 words
An arrangement according to claim 2 including: a third filler panel having its length in its installed position generally parallel to one of said two sides, said third filler panel being of generally channel-shape in cross section and having a web and opposite edge legs, one of said legs of said third panel including means for engaging distal edge portions of said framing flange means extending along one of said two sides of said opening, and the other of said legs including tab means at the opposite ends thereof movable to a position to engage distal edges of said other legs of said one and said second filler panels.
Claim 5
Dependent Claim
60 words
An arrangement according to claim 1 wherein: said one leg of said filler panel includes an outwardly directed flange extending along at least a portion of said leg length, said last-named flange including discrete tab portions at the ends thereof, said tab portions being adapted to be bent to a position behind said framing flange means for locking engagement therewith.
Claim 6
Dependent Claim
88 words
An arrangement according to claim 3 wherein: each of said other legs of said one and said second filler panels has a depth in excess of the depth of said framing flange means; and said opposite end tab means on said others of said legs are spaced from said web a distance to locate the edges of said tab means facing said web means in engagement with the distal edge of said framing flange means when said planar end portions of said web are in said seated position.
Claim 7
Dependent Claim
31 words
An arrangement according to claim 5 wherein: said others of said legs of said one and said second filler panels include notches to receive said tab means of said third panel.
Claim 8
Dependent Claim
170 words
An insertable filler arrangement for reducing the size of a quadrilateral opening in the wall of a cabinet, the perimeter of the opening being framed by inwardly-directed flange means, said arrangement comprising: at least one filler panel of generally channel shape in cross section and including a web and opposite edge legs; said leg on one edge including means for engaging with said perimeter flange means along one side of said opening to prevent displacement of said panel both sideways and outwardly of said opening; said leg on the opposite edge including deformable tab means at the opposite ends for engaging with said perimeter flange means extending along the two sides of the opening adjacent said one side to prevent displacement of said panel outwardly of said opening; and said web including opposite end portions seating upon the outer face of said wall on portions thereof bordering said opening along the two sides of said opening adjacent said one side to prevent displacement of said panel inwardly into said opening.
