Claim 9

A building panel for exterior and interior wall and roof surfaces, comprising: an elongated body formed of relatively thin, hardboard material, having upper and lower edges, a molded outer face adapted for exposure to the weather, and a back face opposite said outer face and having a contour generally matching that of said outer face; said body including a lower edge portion extending along a lower edge of said panel integrally joining an intermedia facia portion spaced outwardly of said lower edge; an elongated fastener receiving strip integrally joining an upper edge of said intermediate facia portion and including a plurality of longitudinally spaced apart, integrally molded fastener receiving depressions projecting inwardly from the intersecting surface of said outer face immediately adjacent an edge of said depressions, each of said depressions having an inwardly sloping wall surface with a depth greater than the nominal thickness of said panel between said outer face and said back face, said depressions aligned in a row on said strip between said upper and lower edge of said panel, said strip having a machined back surface comprising a portion of said panel back face formed by machining after said depressions have been formed in said panel, said machined bakc surface having a generally planar face intersecting said sloping wall surface of said depressions thereby forming an open slot for receiving a fastener extending completely through said panel between said outer and back faces thereof; an upper edge portion joining an upper edge of said fastener receiving strip adapted to underlie a lower edge portion of a panel laid up in a next higher course; a joining strip on said back face adjacent a lower segment of said intermediate facia portion, said joining strip adapted to provide an interlocking relation with said upper edge portion of at least one panel in adjacent lower course; and stop means on said joining strip for self-alignment of said panel with said one panel in an adjacent lower course when said panels are installed in interlocking relation.

Claim 10

The building panel of claim 7 wherein said stop means includes an elongated rib projecting from said joining strip toward said back face of said intermediate facia position for engagement with said upper edge of said one panel.

Claim 11

The building panel of claim 8 wherein said rib has a relatively small transverse cross-section and is shearable from said joining strip to permit relative sliding movement between said panels while in said interlocking relation.

Claim 12

A panel adapted to be attached to a supporting structure with at least one fastener extending through the thickness of said panel; a depression molded into one face of said panel having a plurality of wall surfaces extending inwardly and sloping toward the opposite face, at least a portion of said wall surfaces having a depth greater than the normal thickness of said panel measured at an area immediately adjacent said depression directly between said opposite faces, a machined surface formed on said molded depressions having a generally planar surface intersecting said wall surface of said depression thereby forming an open slot extending completely through the thickness of said panel for receiving a fastener, said plurality of wall surfaces disposed on opposite sides of said slot sloping inwardly of adjacent flanking portions of said outer face toward one another toward said back face.

Claim 13
