Nov. 17, 1964 R. A. DOMAR SHEET METAL SIDING Filed June 16, 1961 P b i INVgVTOR.

0 cr' 077107 BY /7 afi ys United States Patent 3,157,003 SHEET METAL SIDING Robert A. Domar, Carpentersville, Ill., assignor to US.

Aluminum Siding Corp., Franklin Park, Ill., :1 corporation of Illinois Filed June 16, 1961, Ser. No. 117,757 1 Claim. (Cl. 50-230) Another object of my invention is the provision of an improved siding panel having novel longitudinally extending flanges arranged to cooperate with complementary flanges of adjacent panels to afford a sealing interlock between the adjacent panels.

Other and further objects and advantages of my invention will become apparent from the following description when the same is considered in connection with the accompanying drawings, in which FIG. 1 is a fragmentary perspective view showing the siding panels of my invention as installed on a building wall surface;

FIG. 2 is a vertical end view on an enlarged scale, showing adjacent panels mounted on a wall surface and showing the cooperating flanges of adjacent panels in assembled relation;

FIG. 3 is a fragmentary cross-sectional view taken through the upper portion of one of the siding panels;

FIG. 4 is a view similar to FIG. 3 taken through the lower portion of a siding panel,

FIG. 5 is a view looking in the direction of the arrows 55 of FIG. 4.

Referring to the drawings, the clapboard siding panel of my invention is formed of suitable sheet metal such as aluminum or other non-corrosive metal and includes a planar body portion 10, the upper marginal edge portion 11 of which is formed as illustrated in FIGS. 2 and 3 of the drawings. Said marginal edge portion includes a nailing strip 12 adapted to lie substantially flat against a supporting surface 13 and to be secured to said surface as by nails. Integral with the lower edge of the nailing strip 12 is a composite flange comprising a relatively flat portion 14 inclined downwardly and outwardly relative to the nailing strip. The portion 14 is connected integrally with a reversely bent inner portion 16 having a bead 17 formed intermediately thereof and extending longitudinally of said panel. The portion 18 connecting portions 14 and 17 is substantially semicircular in cross-section. The top of the inner portion 16 is flat and is integrally connected with the planar portion 10 by an arcuate portion 19.

The lower marginal edge portion 21 of each panel is formed substantially as shown in FIGS. 2 and 4 and includes an inwardly directed horizontal flange portion 22 connected by an arcuate portion 23 to the planar portion 10. Said arcuate portion is disposed below the plane of the horizontal flange portion 22 and affords a trough for the collection of moisture or condensate. At uniformly spaced intervals the metal is pierced to provide weep holes 24 for drainage of the condensate. The horizontal flange portion 22 is connected with an upwardly and forwardly bent portion 26 by an arcuate portion 27 with the portion 26 terminating in a strip 28 bent substantially at a right angle to the plane of said forwardly bent portion 26.

3,157,003 Patented Nov. 17, 1964 The present invention is concerned with. the joining of overlapping siding panels, as above described, so as to provide an interlocking of adjacent cooperating marginal edge portions to alford a weather-tight connection between them.

Referring to FIGS. 1 and 2, the siding panels of my invention are attached to a wall surface 13 by starting at the bottom and working upwardly. Before attaching the lower-most siding panel a starting strip 29 is first attached along the bottom of the wall surface, said strip having along its upper marginal edge a formation corresponding to the upper edge portion 11 of a siding panel, as hereinabove described. The lowermost siding panel is then applied by inter-engaging the lower edge portion 21 thereof with the flanged formation 11 of the starting strip 29 in the manner illustrated in FIGS. 1 and 2. The nailing strip 12 of said panel is then secured to a supporting surface 13 as by nails.

It will be apparent by reference to FIG. 2 that the flanged formation of portion 11 affords an outwardly flaring throat or opening to receive the companion flanged portion 21 of the adjacent siding panel. The bead 17, however, is so positioned in relation to the planar portion 10 and in relation to the portions 26 and 28 of the lower marginal edge portion 21 as to resist the entrance of said portions into the area inwardly of the bead 17. However, in assembling two adjacent siding panels, it is required to flex the portions 14 and 16 slightly when inserting the portions 26 and 28. After the connecting corner of portions 26 and 28 passes the bead 17, the portions 14 and 16 tend to return to their normal position. Thus, the cooperating portions of adjacent panels are resiliently engaged along three separate lines of contact effecting a substantially water-tight seal between them. For example, a line of contact A is established between portion 26 and bead 17. A second line of contact B is established between the arcuate portion 27 and the face of the planar portion 10 and a third line of contact C between the arcuate portion 18 and the horizontal flange portion 22.

As will be apparent successive panels are applied to a supporting wall surface in the manner hereinabove de scribed until the entire surface is fully covered.

Various changes coming within the spirit of my invention may suggest themselves to those skilled in the art; hence, I do not wish to be limited to the specific embodiments shown and described or uses mentioned, but intend the same to be merely exemplary, the scope of my invention being limited only by the appended claim.

I claim:

A siding for a building structure comprising a plurality of elongated sheet metal panels interengaged to form a continuous siding, each of said panels having a planar body portion and having along the upper marginal edge portion a nailing strip, an outwardly and downwardly inclined composite flange portion between said nailing strip and planar body portion and formed by an upper relatively flat portion inclined downwardly and outwardly from said nailing strip and an integral inner portion bent reversely from the lower margin of said flat portion on a rounded substantially semicircular edge and presenting a Hat inclined section in abutting contact with said flat portion adjacent to the upper margin thereof whereat the composite flange may flex, a protruding head on said inner portion having a maximum displacement from said fiat portion between the upper and lower margins thereof, the lower longitudinal marginal edge portion of said panel being formed to provide an inwardly directed substantially horizontal flange, there being an integral longitudinally extending trough formation disposed below the plane of said flange and connecting said planar body portion and said horizontal flange, said trough formation having a series of spaced apertures therein, said horizontal flange having an end portion longitudinally bent first upwardly and outwardly and then upwardly and inwardly to form an inwardly directed longitudinally extending rib at said horizontal flange and an outwardly directed longitudinally extending rib thereabove, the horizontal flange of one panel being adapted to resiliently' interengage with the composite flange portion of an adjacent panel and aflording substantial resilient sealing along multiple longitudinal areas of contact, one of said areas of contact formed between said last-mentioned rib and the composite flange portion above said protruding head in consequence of the springing of said last-mentioned rib into the restricted space defined by said bead and planar body portion, a second area of contact formed between said first rib and planar body portion, and a third area of contact formed between the lowermost rounded edge of the composite flange portion and the upper surface of said horizontal flange.
