nppH-catio n filed may 29,

My invention relates principally to single course all-steel car roofs andhas for itsprincipal objects" to simplify and cheapen the construction and application thereof to V the framework, and to enable the sheets to accommodate themselves to the distortions of i a the framework incident to service conditions.

The invention consists. in the parts and in the combinations aiid'arlaligements of parts '10 hereinafterdescribed and claimed. In the accompanying drawings, which form part of this specification; and wherein like [symbols refer to like 'parts wherever theyoccur,

The angular side seam .flanges,14c of-the tions 16,. whose surfaces arefsubstantially fiush'with the upper surfaces of said flanges.

'covers,'whicl1 straddle the car-lines and the seam flanges, have a full bearing against the carlines and seam flanges and thus firmly clamp the seam flanges to the earlines.

As shown inthe drawings, the seamcovers D are positively secured to the carlines at the ridge and adjacentto thee'aves, preferably by rivets '17 that pass through sald covers and theraised middle portions 16 oi the oar-lines. The seam covers are turned down at the eaves to cover the ends of adjaoent sheet flanges and have de ending 'entl" flanges 18 that overhang the depending end flanges 12 of the earli nes and are rigidly secured thereto by horizontal rivets 19. As showirin 6, the side marginal portions of the depending. end flangeslS of the seam covers are oiiset outwardly,- as at 20, to aceominodate theadjacent end portions o'lithe dependingeavesflanges'13 ofthe sheets, and are spaced I far enough from said eaves fiaiiges toper nit limited angular adjustment thereotduring' the racking and weaving 0t the ear trainejin service.

The reamin -teale921 extend longitudinally of the car at the rltlge and are preterablyisupp'orte'd on and secured to the lateral top flanges of fZ-shaped r nning-tome saddles 22 whose lateral base flanges rest on the seaiil covers ntl are seeured in position by means .or the'rivets that secure the ridge portionsof said seam oojvers to the 'carlines. Ii desired, the root frame may be further strengthened by securing a ridge pole or along the'ir sides by thefoarlines to which they ai'efirinly elamped. in position to eX- cludethe weather; but th'at'in case of the istortiohotfithe Car frame, the sheets move with th e earlines independently ot the remaihder oft'h'e roof irame and'a-re adapted to accommodate themselves to such distortlon by the flex ng or bendlng of their concav ely curved body portions. It is also noted that the coneave body portions'or" the sheets operate to convey moisture on the seams tothe middle of the sheets, thereby greatly simplifying the problem of 'n'i'aking a water tight seam betweenadjaeent sheets.

It is f noted that the 'coneavely" curving "or bowing of thebodyportions of thesheets enables said body portions to be supported direetlyonthe purlins andside-pl'ates in the plane of the bottoms of the earlines without the use of filler strips or purlins that are offset upwardly between earlines, thereby permitting the use with relatively deep earlines of relatively shallow seam eovers'and roof sheets havingrelatively shallow seam flanges.

th'er advantages of the above roof are its great simplicity and cheapness of constructionfthe faiiility with which it may be applied, and the elimination oi perforations "in 'thesheets @bviously, the hereiribetore described eonstruetion admits of considerable mod fication without departiiilg from thefinvention;
