tion of the type referred to which will enable the shingling, or assembling by overlapping, of an n per sheet with a lower sheet to be. accomplis ed in a eedy and convenient manner. Further an more limited objects of the invention will appear hereinafter and will be realized in and through the contruction and arrangement of parts shown in the drawing, wherein Fig. 1 represents a bottom plan view of the overlapping ends of a pair of sheet metal units constructed in'accord-. ance with my invention, certain parts being shown in section; Figs. 2 and 3 are details in perspective of the opposite ends of a sheet, showing the manner in which the ribs are p formed for the purpose of shingling or overlapping; and Fig. 4 a sectional view corresponding to the line H of Fig. 1.

Describing the parts by reference characters, A, A represent generally apair ofsheetmetal units, each consisting of a flat mesheet 1 which has hollow triangular ribs" pressed therefrom, the preferablyextending from oneside onlyof the sheet. Each such rib consists ofa; base 2 and convergent sides 3 which merge at their ends wit the. sheet 1, there being a narrow slot 4 provided at one endof the sheet. The ribs extend continuously across the sheet, in the form shown in Fig. 2, until a short distance before the opposite end of the sheet is reached. Each rib is then narrowed, as shown particularly in Figs. 3 and 4 and at the right of Fig. 1, the amount of the narrowing being suflicient to' enable the narrowed end of the rib to be received within the end of a rib, of the-shape shown in Fig. 2, on another sheet. The sides of the narrowed end of the rib are designated at 3 and the bottom at 2; and the extreme ends of the sides ,3 are tapered toward each other, as shown at 3", with a like' tapering of the outer end 2 of the bottom 2. reduction in the width of the ends of the ribs is attended with a corresponding reduction in the width of the slots between the upper ends of the ribs, the narrowed portions p of the slots being indicated atA and 4". The

portions 3' of the sides are connected with the-mainportioi1s 3 by beveled surfaces 5. With t e parts constructed and arranged as described, two of the sheets A may be assembled quickly and conveniently b inserting the reduced ends 2"-3 of the ribs at one end of a sheet into the open ends 2, 3, of the ribs at the op site and of a like sheet. The ta ering of t e sides 3 and the narrowin o the bottom 2" of the insertable ribs facilitates the assembling o ration; and them- This a clined surfaces 5 provi e a wedge stop which will limit the insertionv of the ribs of one sheet. within those of another and thereby define a uniform amount of overlapping of 3 one sheet with another.

Afurther advantage of this invention is that it enables the sheets to be assembled u ckly at an place and without the necessity for having their bodies in the same plane when' the assembling. operation is started. The sheets thus assembled may be taken to thejob and there applied to the supporting beams or purlins inthe usual manner. 1

Having thus described a, invention, what I claim is 1. A sheet metal foundation for roofin construction, the same comprising a sheet having hollow triangular ribs extending from one side thereof, there being a narrow slot provided between the ,sides of each rib and the body of the sheet, whereby the surface of the sheet opposite the said ribs is a substantially continuous load-carrying surface, the end portions of the ribs at one end of the sheet each having their sides and hottoms of less width than the-body portions of F .such sides and bottom and the ends of such the opposite end of the sheet, whereby the assembling of the said sheet in overlapped relation with a like sheet is facilitated.

2. A sheet metal foundation for roofing construction, the same comprising a metal sheet having hollow ribs extending from one side thereof, there being a narrow slot provided between each of the ribs and thebody opposite the said ribs-is a substantially continuous load-carrying surface, the end portions of the ribs at one end of the sheet diminishing in cross-sectional area toward such end and being provided on each side thereof with a projection constituting a stop to limit the insertion of such reduced ends of the ribs of said sheet into the ribs on the opposite end of a like sheet.

A sheet metal foundation for roofing construction, the same comprising a metal sheet having hollowtriangular ribs extending from one side thereof, there being a narrow slot provided between the sides of each rib and the body of the sheet whereby the surface of the sheet opposite the said ribs is a be secured.
