Aug. M6, 1938.. E. s. COPELAND METAL ROOF JOINT Filed Oct. '7, 1936 2,127,392 Patented Aug. 16, 1938 2,127,392 UNITED STATES PATENT OFFIQE 2,127,392 METAL ROOF JOINT Elisha S. Copeland, Batesburg, S. G. Application October 7, 1936, Serial No. 104,539 1 Claim. This invention relates to metallic roofs of sec tional formation, and has for the primary object the provision of means for joining the sections of the roof together to provide weather or leak proof joints therebetween and which are easy and quick to assemble and will provide drains to said ‘joint and permits the sections to be read ily stacked one upon the other for easy handling 10 and shipping. With these and other objects in view, this in vention consists in certain novel features of con 15 straight edge 1 abuts one of the walls of the rib 5 and the abutting wall of the latter is dis posed substantially straight while its companion wall is disposed at an inclination, as shown at Ill. The ribs 4 and 8 are provided with indenta tions H for the purpose of receiving the pointed 5 ends of nails or like fasteners employed for se curing the sections to the roof construction. After the assembly of the sections, the ribs 5 at spaced intervals are clinched or bent down wardly, as shown at L2, to overlie the straight 10 struction, combination and arrangement of parts edge 1, thereby ?rmly locking the sections to to be hereinafter more fully described and gether. When the ribs of the sections are inter locked, as described, leak-proof joints are pro claimed. For a complete understanding of my inven tion, reference is to be had to the following de scription and accompanying drawing, in which Figure 1 is a fragmentary perspective view il lustrating a metallic roof constructed in accord ance with my invention. Figure 2 is a sectional view taken on the line 2-2 of Figure 1. Figure 3 is a sectional view taken on the line 25 (Cl. 108-18) 3-3 of Figure 1. Figure 4.- is a fragmentary edge view showing one end of one of the sections. Figure 5 is a view similar to Figure 4, showing the opposite end of the section. Referring in detail to the drawing, the nu 30 meral I indicates generally a metallic roof made up of a plurality of overlapping sections 2 each of metallic sheet formation and constructed in accordance with the present invention. Each section 2 has formed along one edge an upstand 35 ing ?ange 3 and spaced ribs G and 5 adjacent thereto. The section 2 adjacent an opposite edge is provided with spaced ribs 6 and a straight edge ‘I. The section 2 between said ribs is provided Vided between said sections which will exclude weather elements and should rain or the like get between the overlapping portions of the joints it will be caught and carried oif by the troughs 9. Before application of the sections to the roof construction they may be stacked one upon the other with the ribs inter?tting so as to facilitate 20 handling and shipment. _ Having described the invention, I claim: A metallic roof construction comprising a plu rality of metallic sheet sections adapted to be laid in overlapping} relation and each section being bent to provide at an underlying edge an upstanding flange and a pair of spaced ribs adjacent thereto, and a second pair of ribs lo cated adjacent the opposite edge of said section, one of the ribs of said ?rst mentioned pair of ribs of the underlying edge having a substantially straight upstanding wall and a wall disposed on an inclination thereto, the other rib of the ?rst mentioned pair of ribs of the underlying‘ edge ?tting into one of the ribs of the second-named 35 pair of ribs of the overlapping edge with the up standing flange engaging tightly against a wall with a reinforcing rib 8. The ribs heretofore of the other rib of said second-mentioned pair 40 referred to are formed in the section by pressing of ribs of the overlapping edge and the other the material of said section and which provides - rib of the ?rst-named pair of ribs of the under~ 40 in an opposite face of the section grooves. lying edge being clinched at spaced intervals The sections 2 are assembled upon a roof con against the overlapping edge with the. non struction, as shown in Figure 1, that is, said sec flanged overlapping edge bearing tightly against 45 tions are arranged in overlapped relation so that the straight wall of the last-named rib thereby one of the ribs 6 receives therein the rib ll of cooperating with the clinched portions in‘ pre- 45 the adjacent section. The other rib 6 receives venting the sections from moving out of over therein the upstanding ?ange 3 cooperating therewith in forming a drain trough 9. The lapping relation. ELISHA S. COPELAND.
