, line 11-11 of Fig. 10; Fig. 19. is a detail To all whom it may concern.'

Be it known that LWVILLrAM AA.. BREWER, a citizen of the United States, and a. resi-- dent oit the city of Pittsburgh, in the county of Allegheny and State of- Pennsylvania, have invented a new and useful improvement in Car-Roofs, of which the following is a specilication. g

This linvention relates to car roofs and m re particularly to outside vmetal roofs.

t has for its principal objects to produce an' improved'roof comprising a plurality of metal sheetsmovably mounted on the substructure andijhaving their marginal portions arranged to coperate with holldvv,

. metal seam caps so as to provide flexible waterproof seam joints; to ,v provide novel means for securing the seam caps to the substructure; to Iprovide an improved support for theirunning board saddles in vconjunction with the seam caps; and vto attain certain 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 this specification and wherein like symbols refer. to like parts whereverA they occur,-Figure 1 y isa fragmentary side elevation of the top portion of a car, showing a seam cap and cooperating p0rtions of roof sheets embodying the invention; Fig. 2 is a section, on an enlarged scale, through a seam cap and adjoining portions of two roof sheets; Fig. 3 is a top plan view of the end portion of a seam cap detached( Fig. 4 is a section onlor about the line 4 4 of Fig. l; Fig. 5 is a trans verse section through the roof in the region of the ridge pole, the seam cap and runir ing board saddle being shown partly in section and partly yin elevation; Fig. 6 is a section through the seam cap and securing clip for the running board saddledetached; Fig. 7 is an' inverted view of one ofthe securing members for the seam cap; Fig. 8 isa section on a line 8 8 of Fig. 7; Fig. 9 is a section through the roof in `they region of the cuves. showing a modification ofthe seam cap and roof sheets; Fig. 10 is a transverse section through the roof in the region of the ridge pole, showing the seam cap illustrated in Fig. 9; Fig. 11 is a section on the Spe'cication of Letters Patent.

View of the securing member for the seam cap shown in Fig. 9; Fig. 1,3 is a section through the eaves portion of the roof, lshowing the seam cap and securing member therefor in section and also showing a further modification of the roof sheets; Fig. 14 isA a section through the seam cap and adjoining portionsv of' two roof sheets, showing a modification of the marginal formation ofthe roof sheets; Fig. 15 is an end view of a roofing sheet as illustrated in Fig. 9; and Fig. 16 is. an end view ofthe roofing sheet shownin Fig. 13.

, The roof sheets 1 are'movably mounted on the wooden sheathing 2 of the substrrcture. The substructure may comprise any suitable framing. As shown in the drawings, the framing includes side plates 3 and a ridge pole 4. The carlines or transverse frame members are omitted, as t ey form no part of the present invention. The side sheathing '5 is fastened to the side lates, and over this sheathing is placed IBF molding or fascia 6 for protecting the roof covering in case the car side scrapes"; The roof sh ets 1, as shown, extend transversely all e way across the car and terminate at or near the eaves, and the sheets may be adapted; either for a peaked roof, as shown, or a curved arched or radial roof, as desired.'l The ends of the sheets may be turned down over the eaves, or as shown in Figs. 1 and 4, the ends of the sheets may be 1 turned back under the body and spaced e usual eavesI eaves flashing strips 9 whose outer marginal portions are turned down 'against the side of the car, as at 10, and nailed thereto.

ln Fig. 9 the eaves flashing 9a has a rebent inner marginal portion 8, the arrangement being similar to the flashing 9 except that said flashing 9a and its rebent portion 8a is narrower. In both cases, the flashing rests on a rabloeted portion of the roof sheathing 2. The rootl sheets 1 shown in Fig. 9 merely have their end portions offset downward so as to provide a lip 11 which rests on said flashing 9a between the eaves and the rebent portion 8a. A still further modification is shown in Fig. 13. The eaves.

latter terminates approximately flush with the outer face of the side plate 3. The top edges of the side sheathing 5 and the eaves molding 6 terminate on a line with the top of the side plate. The ends ofthe roof sheets are flexible, and are bent down and out, as at 12, so as to provide a springy lip which rests on the flashing between the eaves andthe end of the roof sheathing.

The side marginal portions of the roof sheets 1 are turned back over the body portion and may be either' flanged upward as at 13, as shown more clearly in Figs. 2, 11 and 15, wherein the flange comprises the two thicknesses of the metal pressed close together, or said two upstanding thicknesses of metal may be spread apart to provide a hollow upstanding rib 13 whose outer wall is vertical and inner wall is inclined as shown more clearly in Figs. 14 and 16. The extreme marginal portion 111 of the turned over portion of the roof sheet is bent upward and back over said turned over portion at an inclination, as shown by full lines in Figs. 15 and 16 and by dotted lines in Figs. 2, 11 and 14, before the sheets are applied to the roof. These marginal flanges 14E are adapted to be bent down upon horizontal flanges 15 extending from the lower edges of the side walls 16 of seam caps 17 which hold the roof sheets down and c0- 'operate with the marginal portions of the sheets to make waterproof seams. The normal distance between the edge of the flanges 14 before they are bent down and the flanges flanges 14 and the flanges 13 or ribs 13EL is y such that the flanges 14 will still overlap the flanges 15 of the seani cap if the roof sheet is moved until the flange 13 comes in Contact with the adjacent-side wall 416 of the seam cap. This arr-.ngement allows considerable movement of he roof sheets to compensate for the'weaving and racking motion of the car substructure without nullifying the waterproof qualities of the seams.

The seam caps, like the rof sheets, extend continuously across the car. They may be pressed out of a single sheet of metal. As shown in Figs. 1 to 6, inclusive, the seam caps are of inverted channelshape, having plain flat top walls and straight vertical side walls with marginal flanges. The ends of the seam caps are formed by slitting the upper corners and turning the side wall portions inward so as to overlap each other, and then turning the top wall down over 'said inturned side wall portions and riveting the parts together, as at 18. The downturned top wall is extended down beyond the end of the roof sheathing and into the rabbeted portion of the eaves molding or deeper than the cap shown in Figs. 1 to 6 inclusive. So, too, the end formation of the seam cap is somewhat different. Instead of slitting the cap and making the folds as shown in Figs. 1 to 6, inclusive, the metal is crimped and die-shaped, as at 20, the end of the seam cap extending down below the eaves, as at 19.

The seam caps are supported on the roof sheathing by brackets or clips having key slots for the reception of fastening bolts which are secured through the substructure. As shown in Figs. 1 to 8, inclusive, the seam caps are secured to U-shaped sheet metal clips 21 having marginal flanges 22 which are riveted to the top wall 17 of the seam cap. These clips are provided with key slots 23 having enlargements 24 which are counterparts of the heads of fastening bolts 25, so that said bolts may be inserted in said slots by first passing the head of the bolt edgewise through the enlargement 24 and then turning the body of the bolt into the slot 23. After the bolts have been placed in the clips they are dropped down through holes provided therefor in the sheathing and-side plates and ridge pole, and at any other point on the substructure where the securing clips happen to be placed. In practice, three of the clips are ordinarily provided for each seam cap, one being located at the ridge and the two others -over the side plates. In some cases, h0w-` ever, more of the clips may be used at intervals throughout the length of the seam The 'supporting brackets Q1 shown in figs. 9 to 13, inclusive. may be of 1nalle able castings. They have plate portions 22 which are riveted to the top wall of the seam cap and a bottom plate portion provided with a slot 23 adapted to receive the fastening bolt 25.

In the case of a peaked roof, there is obviously a special supporting'bracket or clip provided at the ridge so as to correspond to the inclination of the roof on opposite sides of the ridge. As shown in Fig. 5, the sheet lnetal clip 21 is identical With the clips over the side plates except that the flanges 22 are intacte as to retain the roofing sheets yet the fastening is somewhat flexible and the roofing sheets are permitted considerable movement to compensate for the Weaving and racking of the car. The peculiar seam arrangementy afforded by the cooperating flanges or

ribs

13 or 13, Aas the case may be, and the down-turned flanges or ,lips 14 Which overhang the llanges 15 of the seam caps, makes it practically impossible for Water to percolate or be driven in under the seam'cap. Any Water which may enter under the flange or lip 14 Will be readily conducted ofl through the space between the end of the flange 15 of the seam cap and the bend at the base of the flange 14; and should any Water be driven With such force that it will get under the flange 15 of the seam cap, it will be conducted oil through the space between the llange 1.3 or rib 13a, as the case may be, and side Wall 16 of the seam cap, as thev area is considerably greater than, the opening through which the Water enters.

The running board saddles 26 are sup ported on the seam caps by ltshaped metal clips 27. rlhe side portions of these clips are perforated, as at 28, to receive bolts 29 which are passed through horizontal holesl in the running board saddles. rlhe bottom portions of the clips rest flatvvise on the seam caps-and are fastened by rivets 30. The same rivets may also be used to tasten supporting clips 31 located under the seam caps and resting on the root sheathing` 2. The supporting .clips 31, as shown in Figs. 5 and 6, are of' inverted Ushape and have marginal flanges 32 which rest flatvvise on the roof sheathing. 'By this arrangement, the running boardfsaddles have a firm sup port and the seam caps are prevented from being crushed in, Without taking 'from the desired flexibility of the roof structure.

Obviously, the construction and arrangement of the several parts admits of considerable modification Without departing.

from the invention. Therefore, l do not Wish to be limited to the specific construction and arrangement shovvh.
