Application ied Jury 31, 1912. serial No. 712,423.

` more particularly to outside metal roofs.

It has for its principal objects to improve .upon the construction and arrangement of the roof and of the fastening means for the roofing sheets in thepregion of the eaves; to provide vfor considerable radial movement of the roof in order to compensate for the weaving and rackin motion of the car body and thereby preven the concentration of stresses which tend to tear the sheets; to provide for mounting the securing clips or hood castings on top of the roof entirely within the side lines of the car body and without perforating the roofing sheets proper; to obviate the necessity for providing a fascia or protective molding along the sides of the car body at the eaves; and

i to attain certain other advantages which will hereinafter more fully appear.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings which form part of the specification and wherein like symbols refer to like parts wherever they occur z-Figure 1 is a fragmentary view, showing in elevation, a portion of a car body in the region of the eaves and also adjacent to a roof seam; Fig. 2 is a vertical section taken on or about the line 2 2, of Fig. l; Fig. 3 is a vertical section taken on or about the line 3-3, of Fig. 1; Fig. 4 is a fragmentary perspective view of the portions of two roofing sheets adjacent to the eaves margins and side seam, and also showing the coperating dashing sheets and joint shield; Fig. 5 is a pers ective view of a hood casting detached; ig. 6 is a fragmentary view, in section, showing how the flanged perforations in the ashing sheets cooperate with the flanged bolt holes in the hood casting; Fig. 7 is a View similar o Fig. 2 showing a modification of the roofing and flashing sheets; Fig. 8 is a perspective view of the flashing sheet of the structure shown in Fig. 7; and Fig. 9 is a perspective view of the flashing joint shield.

The wooden substructure of Ythe roof comprises a side plate 1 to which the side sheathing 2 is secured, and a supplemental plate or filler 3 which is inserted between the top of the side plate proper and wooden sheathing 4 of the roof, and extends over the side sheathingr 2 so aspto be fiush with the outer face of the latter. The Wooden roof sheathing is rabbeted or grooved for a considerable distance inward from the eaves to accommodate the rebent marginal portions of the metal roofing sheets and cooperating portions of the eaves flashing in order to allow the end portions of the roofing sheets to lie in the same plane as the body portions, which latter rest on the wooden sheathing, as will be hereinafter more fully set forth.

Referring now more particularly to the structure shown in Figs. 1 to 4, inclusive, the metal roofing sheets 5 are shown connected by high seams (i made by overlapping rebent marginal portions of the sheets. The eaves ends of the sheets are turned under, and the doubled under portions coperate with the turned' over inner marginal portions 8 of flashing sheets 9.

The flashing sheets 9 rest on cutaway or rabbcted portions of the wooden sheathing et and they are turned down over the eaves,

the turned down portions 10 being nailed or otherwise fastened to the side sheathing Q. These flashing sheets, as shown in Figs. l and el, are made to abut at their ends, ang adjacent to the joints they are corrugate or provided with pressed-up hollow ribs 11 which extend crosswise of their middle lengths. These hollow ribs stiffen the flashing and also support the end portions 7 fof the roofing sheets proper. Under the flashings, et each joint, is placed a shield 12 whose inner and two side margins 13 are flanged up slightly, and whose outer end portion 14 is turned down`over the eaves and nailed or otherwise secured to the side of the car. This shield is preferably of such width that its side fianges 13 lie under the hollow ribs or corrugations 11; and its length is such that the inner end flange lies beyond the inner end of the iashing.

Securing clips or hood castings 15 are mounted on the roof at the eaves corners of the roof sheets to co erate with the end portions of the raised si e seams thereof. The hood portion of each casting is arranged so as to straddlo the seam and cover its open end, and `is normally out of Contact therewith on all sides. The side dangesl of the securing clips are preferably concaveconvex in cross section, and are normally 1n Contact with the roofing sheets on oppositesides of the seam. The hood casting has a flat baseor supporting rplate 1T which rests iatwise on top of the eaves flashing. This base portion 17 is pierced with tWo tapered holesv 18 through which lag screws or bolts 19 are inserted into the wooden substructure of the roof. As shown in the drawings, the

lag screws are passed through the Wooden sheathing i and into the supplemental side L plate 3. The holes 18 are smallest at the top, and there are flanges surrounding their tops. To'strengthen the hood casting the vside anges 16 are extended outward beyond are'less liable to side sera e.

*the* hood portion and are turned down where they join the base or. supporting portion 17,

forming end wallsv 16?. The perforations in the dashing sheets 9 and joint shield 12 are :danged upward, forming sloping walls 20 which-project into the tapered perforations 18 in the hood casting base and pre- 1 vent waterrom penetrating the root covering by following the-lag screws or bolts which fasten the hood casting upon the By placingthe hood casting on top of the roof,ventirely within the side lines oit l"the car body as shown, the fascia or eaves molding' may be eliminated as there are no `tor movement to compensate for the weavlis .Inaynct be used, as desired.

lZlhe dashing ing and racking of the ear body.

'ln the structure shown inlFigs. l to 4, inclusive, the corrugations or ribs il, extend from the inner margins of the dashing sheets 9 entirely to the eaves, but in the modication illustrated in Figs. 7 and .8,

thecorrugations or ribs lla entend only for 'a distance 'suiiiwcient to support the rebent ends ot the rooting sheets., the portion of the tias-hing adjacent to the eaves being lett dat kto receive the base portion 1'? of the hood casting. this mcdication, the dashing sheets are made 'te overlap at their ,james that the eorrugations il ci' the adj canning tit the one within the other. 'L'n this construction' the shield 122 or Henares, it is preferable to provide it as shown irji Fig.

95 iliustrated in liigs. Tand d is' mereiy angeli' upward along its inner nlE vbeing rebent; and,

lieu of rebending, a supplemental dashing strip 22 is nailed along the Wooden roof sheathing adjacent to the rabbet so as to overhang the rebends 7 of the roofing sheets.

Obviously, the structure admits of considerable modification without departing from the invention. Therefore, l dov not wish to be limited to the specific construction and arrangement shown.
