METALLIC ROOFING.

- it appertains to'make and use the same.

This invention comprises certain improvements and novel features which are applicable more especially to roofing, but may be also applied in certain cases to walling and ceilir g and structural purposes generally.

The advantages incidental to my improvements, as hereinafter described, are that the several parts constituting the roof, walls, or

ceilings and other structural purposes can be fitted together by mutual interlocking, it only being necessary to secure certain parts, such as the principals,-rafters, or ridge-plates, by nails or the like means, the whole forming when put together a reliable weathertight and water-tight 'structural arrange;

' ment for roofing and other structural purposes and also to prevent or cure damp walls. Having thus indicated the .nature and utility of my invention, in order that it may be clearly understood and readily carried into effect I will proceed to further describe the same, and for that purpose shall refer to the accompanying drawings, in which Figure l is a plan view of a hipped roof embodying my improvements, corresponding to which Fig. 2 1s an elevation. Figs. 3, 4, and 5 -are detail views drawn to an enlarged scale, Figs. 3 and 4 being sections taken'on lines at as and y y, respectively, of Fig. 1, the former showing a ridge or hip principal or hip main rafter with sheathing or binder and the latter bringing into view two principals or main rafters with the intervening interlocked panels or tiles on principal or main rafter running in line with gable-wall. Fig. 5 is a plan view, and Fig. 6 a corresponding sectional view, of a convenient form of overlap between an upper and lower panel or tile, showing the means for preventing stormwater penetrating between the laps. Fig. 7 is a plan view, and Fig. 8 a corresponding side view, of one of the corner-plates for securing additional rotection to the structure. As shown in tfie drawings, I provide as principals or main rafters sheet-iron or rolled girders a of an approxnnate H-sectio'n, it being desirable in this case, as shown in Fig. 4, to have the under side flange of greater width than the upper or top side flange, where fasteners, such as nails or screws, have to be used. A sheathing b, with scroll-shaped dependent extensions 6 6 forming an intervening flat or raised flange-cover, is threaded along the full length of the upper flange of each principal or main rafter a, the scroll extensions first forming insets, with the intervening flange-cover adaptedto embrace the edges of the upper flange of the rolled girders 0r principals, while the parts of each scroll below the insets are curved or coiled to form troughs 1) b the curved edge being coiled over far enough to afford a means of interlock to the edges of panels 0, with similarlycurved edges 0 c to embrace and hook over them. Sheathed principals thus designed are pitched at any suitable distances apart so that the panels or tiles 0, of sheet-iron or any other suitable material, including copper, zinc, or lead, can be inserted between the principals with their inset edges threaded into and interlocked by the scrolled edges b b of the aforesaid sheathing.

Referring more particularly to Fig. 3, in order to further secure such roofing from dislocation by wind-pressure or otherwise the outer edges of the panels are coiled inwardly the following manner: A curved-over upper or outwardly, as required, for interlocking in edge e on the panel hooks into a corresponding inwardly-curved edge I) of a ridge or hip plate 12, which bridges over to similarly hook into the panel on the other side of the roof or hip, so that the strains from the two panels or tiles 0 c on opposite sides of the roof balance or neutralize each other. The ridge or hip plate b takes the form of a triangle in section, the plate meeting along the bottom from either side and after forming right and left hand recesses for interlocking each side returning to form the top plate of the roof, to which it is secured by any suitable means. In order to strengthen such a ridge-plate, an H-bar is threaded into it.

Where the panels or tiles abut against gable ends or walls, as shown in Fig. 4, a continuation of the web to form a wall-plate a takes the place of the lower flange of the principal a, which wall-plate (1 extends down the face of the wall for fastening, the inner side and sheathing taking the form of a scroll pendent, as before, for interlocking with the panel or tile edge Fig. 4 also presents in sectional view an intermediate principal or main rafter a, sheathing b, and anels c, all

interlocked inv the manner herelnbefore de' scribed. I r

Where panels or tiles overlap, as shown in Figs. and 6, it is desirable to run a corrugation e along the edge of the underlapping panel, the corrugation extending upwardly in a manner adapted to form an overlap-joint, so that water must ascend an incline in forc ing a passage through the overlap. Furthermore, the edge of the underlapping panel is turned over at e for further protection, as

chimney-stack a water and weather tight connection is effected by means of theflashing h, as shown in Figs. 1 and 2.

Itwill be readily seen from the foregoing description, taken in connection with the accompanying drawings, that the aforesaid methodsof construction may be considerably Varied in both the general arrangement and 'in detail to adapt my improvements to differently-shaped roofs, or my said invention can with slight modifications be readily adapted .in certain cases to other structural purposes including walling and ceilings as well as for roofing.

Having thus described the scope, extent,

and object of my invention and the manner of performing the same, I wish it to be understood that the method or principle ofinterlocking the several parts to make up a roof or other structural arrangement is not new. I therefore make no claim to such method or principle otherwise than as embodied in and carried into practice by my improvements as above'specified,

Having thus described my invention, what I desire to claim and secure by Letters Patent of the United States is 1.. A metallic roof composed of-principals ormain rafters consisting of girders substantially H-shaped in cross-section, of sheathing provided with dependent extensions terminating in scroll shapes adapted to he slipped over said principals, and panels or tiles, having upturned edges adapted to fit over the scroll-shaped edges of, the sheathing, substantially as described.

2. A metallic roofing consisting of principals or main rafters made substantially H- shaped in cross-section, with sheathing provided with dependent extensions, scrollshaped at their lower edges, and interlocking panels, the upper edge of the upper row of panels being provided with scroll-shaped extensions adapted to engage with the scrollshaped portions of the sheathing, and the overlapping part of the panels being provided with an upwardly-extending corrugation, substantially as described.

In testimony whereof I afi iX mysignature in presence of two witnesses.
