To all whom, it may concern.-

Be it known that I, \VILLLUL A. Bnnwnu, a citizen of the United States, and a resident of the city of Pittsburgh, in the county of Allegheny and State of lelnisylvania, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification.

This invention relates to outside metal ear roofs and is an improvement on the type of root illustrated in the C. (J. Murphy Patent No. 1,133,193 dated March 30, 19 15. In the above roof, the eaves ends of the transverse seam caps are held in position on the substructure by means of angle clips, which are bolted to the side fascia and bear on top of the seam caps. In actual practice, these bolts sometimes extend through the side plates of the car, thus permitting water to follow the bolts and reach the interior of the car and cause the lading carried therein to become damaged. During the service of the car, these clips are liable to work loose and swing to one side, thus permitting the eaves ends of the transverse seam caps to lift up off the substructure and impair the weather- )rooting qualities of the roof. The saddle bolts also are liable to work loose, thereby causing the ridge ends of the transverse seam caps to become disengaged from the center caps and permit the seam caps to slide co1npletely off the car. There is also a practical diiiiculty in preventing leaks at thejoints be tween the ridge seam cap and the sheet an chor saddle, and at the joints between the center caps and the running board saddles, when the securing bolts at these points become loose, as in the case of shrinking of the sheating and ridge pole. Another cause of leakage at these joints lies in slight variations in the milling of the saddles, in consequence of which said saddles are liable to bear against the bossaround the bolt hole in the ridge cap and center ca and force said caps downwardly instead 0 fitting over said boss properly.

The principal objects of the present invention are to overcome the disadvantages hereinbefore mentioned; to loosely secure the eaves ends of the transverse seam covers 'to the substructure without the use of separate securing clips and thereby eliminate all bolt holesin the side plates; to reduce the'cost of manufacture and application of Specification of Reissued Letters Patent.

In the accompanying drawings, a metal roof embodying my invention is shown applied to the ordinary type of car comprising versely iol plates which straddle theridge of the roof and have upstanding bosses 16 formed therein, which project into similar bosses 17 formed in the roof sheets near their ridge ends. The eaves ends of the roof sheets are loosely secured to the substructure by means of angle flashing strips 18. These flashing strips rest in a rabbet formed in the eaves ends of the roof sheathing and extend from end to end of the car passing beneath the mullions and the transverse seam caps. The

- vertical flange of the flashing strip is nailed or otherwise secured to the side of the car and the portion of the strip resting in the rabbet is doubled-back upon itself, as at 19,

and the eaves ends of the roof sheet are doubled-under, as at 20, and hooked into the doubled-back portion of the'fiashing strip.

The side and ridge margins of the root sheets are flanged up and turned in and down forming hooked flanges 21 and 22.- Inverted channebshaped ridge seam caps 23 straddle the spaced ridge margins of each adjacent pair of root sheets and have their lower side margins flanged inwardly and upwardly forming hooked flanges 24 adapted to interlock with the hooked flanges 22 formed in the ridge margins of each sheet. The side margins of the roof sheet adjacent to the mullions 1 1 are covered by transverse seam caps 25, which are similar in crosssection to the ridge seam caps 23. The transverse seam caps straddle the mullions 14 and the side margins of the adjacent sheets and have inwardly and upwardly eX- tending hooked flanges 26 similar to the flanges 24; of the ridge seam caps adapted to interlock with the hooked flanges 21 formed on the'side margins of the roof sheets. The eaves ends-27 of thetop portions of the transverse seam caps are bent down over the end of the mullions '14 and then turned under the adjacent douhledunder flanges 20 of the roof sheets located on each side of the mulhons. movement of the transverse Due to the relative seam caps with respect to the roof sheets,.there is a possibility of the turned-down portion-27- of the seam cap slipping from beneath the doubled under portion thereby causing the side margins; of these parts to but-t against each other and,dau 1age the cap or sheets. This danger is avo ded b making theturneddown portion 27 of the transverse seamcap w der than the dis- 'cap and reaching clamping nuts the saddle bolts 29' and are- 20 of the root sheets,-

tance between the side margin of the roof sheets when the sheets are shifted in opposite directions. The top portions of the transverse seam caps 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 seam caps and the ridge ends of the transverse seam caps are covered by theyusual pan-shaped four-Way center or corner caps 31 having an opening in each of their four walls to receive the ends of the ridge and transverse seam caps. The extensions 28 at the ridge ends of the transverse seam caps have upstanding corrugations 32 extending cross-Wise of the extensions which are adapted to bear against the under side of the center caps 31 to prevent water being blown under the center the interior of the car. These center caps have center holes in their top walls surrounded by upstanding bosses 33 through which the saddle bolts 29 pass. Running boards 34 are secured'to the running board saddles 30 which rest on the transverse seam caps and are supported on the mullions 14 arranged beneath the transverse seam caps, thus permitting movement of the sheets under the transverse and ridge seam caps. The running board saddles are secured tothe substructure by the saddle bolts 29 which extend down through the roof sheathin and ridge pole and are threaded to within a short distance of their head portions. The under sides of'the running board saddles are recessed to receive the center caps which are secured thereto by means of 85. These clamping nuts are threaded on adapted to bear against the underside of the center cap 31 so as to Zlraw the upstanding flange surrounding thebolt hole in the center caj; up into the under side 'of the running oard saddle thereby preventing leakage at these )oints. The lapped portions 28 at the ridge ends of the transverse caps are offset downwardly to rovide space for the clamping nut 35 whie clamps the center ca to the under side of the running board sa (lle.

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 36 which have their under sides shaped 'to fit the pitch of the roof and are provided with circular recesses 37 adapted to fit over the bosses 17 ot the roof sheets The anchorsaddlcs 36 to the substructure by bolts 38 which extend downwardlythrough bossed-up holes 39 in the top of the ridge seam caps The bolts are threaded 'tl1e' greater portion of their length and the r1dge seam caps are secured to thennder side of the anchor,sad
