ltpnlication filed October 14, 1924. Serial No. 743,550.

This invention relates in general to improvements in freight car roofs and more particularly to improvements in car roofs of the type generally designated as outside metal roofs, which outside metal roof covers the inner wooden roof sheathing of the car.

Objects of the invention are the provision of a roof construction which will effectively resist the tendency of movement of the roof structure so that a metallic roof may be ap plied and held thereon in such a manner that the roof sheets will not move or float thereon with attendant chafing of the light gauge metallic parts; the provision on such a roof construction of roof sheets extending); from caves to caves and having side flanges engaging an anchor arranged at each. eaves end of the side flanges so that the anchors hold the roof sheets down on the roof structure, said side flanges and anchors heing enclosed hy side seam caps; the provision of such a car roof construction. permitting), slight movement of the metallic roof sheets should there be any movement of the wooden roof sheathing; the provision of such a roof which is simple to manufacture at a reasonable cost and which can be applied without the necessity of. specially skilled workmen and which when so applied will he Weathertia'ht and not require frequent re pair and replacement; and such other ob 'jects and advantages of the invention as may be found to obtain in the structure hereinafter set forth and claiitned.

Referring to the drawings, the upper part of the car-body, which the supporting; frame worlr for the roof, consists of wooden side plates 10 having their top surface curved, and in the present instance, wooden purlins 11 and wooden ridge pole 12. Secured to the outer face of the side plate is the wooden side sheathinr, 13, the top surface of which is flush with the top surface of the side plate. Secured on the side sheath ing at the eaves edges of the roof are the Wooden side fascia 14:, the top surface of which is flush with the top surface of the side sheathing. The inside Wooden roof sheathing 1.5, consists of wooden roof boards 16, extending diagonally across the car, as shown more particularly in Fig. 1, and curved to conform to the desired curvature of the roof. These roof hoards 16 are each provided with a slot or groove ll" in one side edge and a tongue 18 in the other so that when laid on a car the tongue engages in the slot of the next adjacent board so that when the matched boards are in place they tend to hold each other from movement and rigidity the roof structln'e a unit. llhe shorter boards at each end of. the car are secured to the side plates and end plates 19, and the longer ones are secured at each extremity to the oppositely disposed side plates by suitable fastenings such as by nails 21.

The diagonal arrangement of the roof hoards when matched as described in a struc ture of arched configuration, and secured at the ends, as above described results in a structure which so effectively braces the car that the weaving and other n'ic-veinents of the car are negligible and the construction provides a very substantial rigid roof.

Metallic roofsheets 22, of light gauge metal, formed to conform to the curvature of the roof, are secured on the Wooden roof. These sheets extend from eaves to eaves and are flanged at each side to provide flanges 23, which extend clear across the car, consisting of an upwardly extending and inwardly inclined portion 2 1- rebent at 25 to provide adepending flange 26 spaced from the main body 27 of the roof sheet and also spaced from the upwardly projecting portion 2a. The eaves edges of the wooden roof sheathing are gained out at 28 to receive a metallic flashing 29 having at its inner edge an upwardly projecting outwardly rebent portion 30, the upper surface 31 of which is in a plane beneath the plane of the top surface 32' of the inside wooden roof sheathing. The outer edge of the flashing is bent downwardly at 33 to enclose the edges of the roof sheathing and is then bent outwardly at 3st over the top surface of the side fascia and terminates in a depending iange 35 secured to the outer surface of the side fascia. The eaves edges of the roof sheets are flanged downwardly and outwardly at 35, and terminate in an outwardly pressed longitudinally extending rigidifying head 37 which is spaced from the portion 34. of the flashing. The side flanges of the roof sheets stop hort of the eaves edge of the roof sheets as indicated at 38 (Fig. to facilitate application of the roof sheets.

An anchor is secured at each eaves edge of the car between each two. adjacent roof sheets, said anchor consisting of two horizontal base portions 39 that are secured to the car by'nails 39 or othersuitable means. The base portions are pressed upwardly at '40 to form a bearing for the adjacent side edges of the roof sheets, and these portions 40 are bent upwardly to form vertical contacting members 41 having outwardly extending oppositely disposed horizontal holding down portions l2 connected by a curved top 43. The portions 42 engage over the side flanges of adjacent roof sheets where the flanges are rebent at 25 and hold the roof sheets, at the eaves, down on the wooden inside roof. Y Thesides of adjacent roof sheets are enclosed by two side seam cap 46, which are tubular in cross-section and have curved sides 47 bent inwardly at 4:8 and terminating in upwardly extending flanges d9 which engage in the space between the portions 2% and 26 of the side flanges of adjacent roof sheets, more clearly shown in Fig; 6.

- The eaves ends of the side seam caps are 7 closed by folding'the top portion down at 51 and folding the sides laterally as at 52 over the part 51. At the ridge ends the sides of the cap are cut away and the top continued to form extensions that are lapped one over the other as indi -ated at 55 and the lapped extensions are capped by an inverted U-shaped cap 56 having lateral flanges 57 extending transversely of the car. The lapped ridge ends of the side seam caps are secured together and to the inside wooden roof by a bolt 58 that passes through apertures in the cap 55, lapped extensions 55, the wooden inside roof sheathing and the ridge pole. At its upper end, the bolt tie passes through an aperture in the running board saddle 55) to secure the saddle to the roof. The saddles support the usual running boards 60 and are channeled at (31 on their under side to fit over the side seam caps hereinabove described. The side flanges of the roof sheets are cut away at 51' and the remaining portions pressed to form offsets (32 to permit easy passage of the bolts 58 between adjacent roof sheets.

At each end of the car, wooden inullions are provided, said niullions being enclosed by mullion caps having a depending flange 63 secured to the end of the car and having an inner side flange 65 similar to one llange of the side seam caps herein-above described. The caves ends of the mullion caps are closed by 21 depending flange 67.

One way o t assembling the metallic rool' onto the inside wooden roof sheathing is to first tilt the n'iullion cap (38 and end roof sheet (59 so that their side flanges may be interlocked and then lay them down on the roof, then raise the right-hand side of roof sheet 69 and nail the anchors in place, then tap the anchors on the side toward the roof sheet (59 and lay the roof sheet down so that the top 25 of the side flange rests under the holding down portion 42. Then tap the anchors on the other side and lay the next sheet on the car so that the portion 25 of that sheet fits under the portion 42 and so continue throughout the length of the Then the side seam caps are slid on the adjacent side flanges in the direction of the ridge until the extensions 55 are lapped. Then apply the cap 57 and the running board saddle 59. After the saddles are applied then the bolt 58 is passed through the saddle 59, cap 57, lapped extensions 55, roof sheathing 15, and. ridge pole 12 and secured, preferably by a washer and a nut 72, to the lower face of the ridge pole.
