spacmtllus formed .are arranged niullions or bziittens 14, the Width of the mullions b.- ing less than the space between the roof sheets. These mullions are arranged transversely of the car and extend from the eaves towithin a short distance of the ridge on each side of the car. n

` Each' Y pair of oppositelyI4 disposed roof sheets is pivotally mounted on the roof substructure by means of sheet metal anchor plates 15 which straddle the ridge of the roof and have upstanding bosses 16 formed therein, which project into similar bosses '17. formed in the roof sheets nearr their ridge ends. The eaves ends of the roof sheetsare loosely secured to the substructure by means of angle flashingstrips 18. These flashing strips rest in a rabbet formed inthe strip. 3o

eaves end of the roof sheathing and extend fromend toV end of the cai' passing beneatl-- the Inullions and the transverse seam capsA inverted channel `shaped 'ridge' seam caps 23 straddle the spaced ridge margins of each adjacent pair of roof sheets and have their lower .side margins flanged-inwardly'and upwardly forming hooked flanges 24 adapted te interlock with the hooked flanges 22 formed in the ridge margins of each' sheet. The side margins of the roof sheet adjacent t0 the mullions 14 are covered by transverse seam caps 25, which are similar in cross-sec` tion to the ridge seam caps 23.- Tlie transverse seam 'caps straddle the' mullions 14 and the side margins of the adjacent sheets and have inwardly and upwardly extending hooked flanges i2G similar to the'flanges 24 of the ridge seai'n'caps adapted to interlock with" the hooked flanges'21- formed on the *side margins of' thereof sheets. rThe eaves ends 27`of' the top portions of' the transverse seam caps are bent down over the end of' the mullions 14 andthen turned under the adjacent doubled-under flanges 2010i the roof sheets located on each side of' the mullions. Due to the relative movement of the transverse seam caps with respect to the roof sheets, there is a possibility o t' the turneddown' portion27 of the`se'am. cap slipping" from beneath the doubled-underportion 20 of the roof sheets', thereby causing the side margins of these' partsto abut against each other and dainagethe cap. or sheets. This danger is avoidedv by making the turned! down portion 27 of the transverse seam cap wider thanv the distance between the side margin of the roofsheetswhen the sheets are shifted in opposite directions; The top portions of the transverse seamcaps have extensions 28 which lap at the ridge and are perforated to receive the saddle bolts 29 of" the running board saddle 30.

The ends of the ridge seanicaps and the covered by the vusual pan-shaped four way center or corner caps 31 having an opening .infeach of their four walls to receive the ends ofthe ridge and transverse seam caps. The .eX-tensions 28 at the ridge ends of the transv erse seam caps have upstanding corrugations 32 extendin cross-wise of the extensions which are a apted t0 bear against the -under side' of the center caps 31 to prevent water being blown under the center cap and reaching the interior of the car. These een ter caps have center holes in their top walls surrounded by -upstanding bosses 33 through which thesaddle bolts 29 pass.v Running boards 34 are securedto the'running board .saddles 30 which rest on the transverse seam caps and are supported on the inullions 14 arranged beneath the transverseseain caps, thus ermitting movement of the sheets under t ie transverse and ridge seam caps. The

running board saddles are. secured to the sub` structure by the saddle bolts 29 which extend 'down through the roof sheathing and ridge pole and are threaded to wit short distanceof their head portions. The under sides of' the running board saddles are recessed to receive the center caps which are secured thereto byineans of clampin nuts 35. These clampingnuts are threa ed on the .saddle bolts 29 and are adapted to bear `against the under side of' the center cap vridge ends of the transverse seam caps are l f 3l so as to draw thev upstanding flange surrounding the bolt hole in the center cap up into the underside of the runningl board saddle thereby preventing leakage at these points. The lapped portions 29 at the ridge ends of the transverse cans are oset.downwardly to provide space for the clamping nut 35 which clamps the center cap to the under side of the running board saddle.

The bosses 17 in the roof sheets are held down on the bosses 16 in the anchor plate 15 ,by means of intermediate running board saddles or anchor saddles 36fwhich have their under sides shaped to fit the p'itch of the roof and. are provided with circular recesses 37 adapted to. fit over the bosses 17 of the roof sheets. The anchor saddles 36 straddle the ridge seam covers Iand are secured to the substructure by bolts 38 which exten-d down- .wardly tlirouglrbossed-up holes 39 in the top of' the ridge .seam caps. The bolts are.

threaded `the greater portion of their length andthe ridgeseam caps are ,secured to the under side of' the anchor saddles by clamping lnuts 40, the tightening of which causes the By the arrangement described', the ridge 5 seain caps and center caps can be clamped iirinly to their respective saddles and a tight water proof ]oint between these nieinbers obtained'irrespective of slightI variations in the milling ofthe saddles. This arrangement l also perinits the ridge seain cap and centery dies to the car. l

l'ne turning of the eaves ends of the transverse seam under the eaves ends of the root` sheets, ywhich in turn are loosely held down at the eaves by the eaves flashing strips,l

eliminates the use of all clips and bolts, and overcomes the diiiicnlty formerly encoiin tered in applying these clips to ears having nieta-iside plates. rlhis turning under of the eaves ends of the transverse searn caps also permits the sheets and caps to shift in opposite directions Within certain limits without becoming disengaged 'from each other. The transverse seain caps are held in position on i the ear by ineens of the saddle bolts 29 which pass thron'ghvthe lappedridge ends of the seam caps. i
