Application filed February 2, 1912. Serial No. 675.007.

1 '0 all whom it may concern:

Be it known that I, Junie B. CARMER, a citizen of the United States, residing at Wilmington, in.the county f Newcastle and State of Delaware, have invented new and useful Improvements in Foot Structures for Railway-Cars, of which the following is a specification.

The present invention relates to improvements in railway car st 'uctures, and the primary object of the invention is to provide a roof structure therefor which enables a metal roof to be employed that will fulfil the conditions and requirements, the roofing sections, according to the present invention beilig so held or locked. in position that the entrance of water or moisture is effectively prevented although provision is made for such movements as may occur between the roofing sections and their supports and securing means due to the torsional or other strains to which the car is subject although the roofing sections are so held or looked in position that displacement is impossible, the

structure 1"ovided by the presentinvention being relatively strong, inexpensive to manufacture. and capable of easy assembling, no bolts, screws or nails for securing the carlines, car-line support castings, purlins, roofing sheets or running board supports passing through the exterior exposed portion ot' the roof to the interior of the car, thus preventing water or moisture following the bolts, screws or nails into the interior of the car which is a common evil on existing roofs. Moreover, the upturned flanges of the roofing sheets and the downturned flanges of the carlines, with the purlins as the under supports, lock the roofing sheets in position. avoiding puncturing of the sheets or the contact with the exposed surface of the sheet of a separate clump or auxiliary joint cap, thereby permitting free expansion and contraction of the roofing sheets between the flanges and preventing friction and wear of the exterior portions of the sheets \vhich'would result from engagement of the sheets with separate joint caps or running board-supports. These results are obtained by theuse of a combined carline and joint cap, this construction greatlyreducing the number of parts necessary. Moreover, the employment of a casting which is'fastened to the side plate of the car and which supports the respective end of the carline provides a, waterproof joint for the roofing sheets at the caves and drains away water or moisture which might enter the jointbetween the roofing sheets and thus reach the inside of the car. 4

Another object of this invention is to provide simple and improved means for mounting a. running board on the roof of the car, the running board being so supported as to avoid damage to the roof or joints through which water or moisture might enter.

To these and other ends, the invention consists in certain improven'ients, and combinations and arrangements of parts, all as will he hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

In the accompanying drawing :Figure 1 is a top plan view, partly in section, of a portion of an ordinary railway car provided with a roof structure constructed in accordance with one embodiment of my invention; Fig. 2 represents a' transverse section through the upper portion of the car as shown in Fig. 1 and illustrating the roof structure; Fig. 3 is a fragmentary view of one end of the car roof showing a mode of attaching a carline thereto, locking the adjacent roof section thereby, and mounting the running board on the carline; Fig. 4 is a bottom plan view of one of the spacers which are preferably interposed between and connect the carlines; Fig. 5 is anend view of onev of the carlines as viewed from one of the cave of the roof; Fig. 6 represents a section on an enlarged scale' and in the plane of the line 6--6 of Fig. 2; Fig. 7 is a perspective view of one of the saddles or supports for the running board; Fig. 8 is a perspective view, partly broken away, of one end of acarline constructed in accordance with the present invention: Fig. 9 is a perspective 'view of a portion of a metallic roofing section adapted to be used in connection with the present embodiment of the invention; Fig. 10 is a perspective view of a combined carline support and side 7 plate cap adapted to be used in connection with a carline of the construction shown in Fig. 8.

' Similar. parts are designated by the same reference characters in the several views.

The present invention is applicable generally to railway cars of various types and it possesses important advantages over roof structures as commonly used. particularly in that it provides improved means whereby metallic roofing may be employed, avoiding the common defects of corrosion of exposed vsurfaces resulting from wear at the run avoiding .leaka e of water and moisture into the car. carline and roof sheet jbint cap into one unitary structure ,and the employment of the combined carline support and side plate cap renders the above condition possible and greatly simplifies the roof construction.

In the accompanyingdrawin the roof structure is supported by longitu in'al frame members, commonly known as side plates 1, which may be either'of wood or metal, and

end frame members, commonly known as end plates 2, which may be either of woodsuitor metal, these frame members*fbeing1 er of ably supported by underframing eit v wood or metal at thetop andinner side of 95 the siding .3, and the usual fascia boards 4 are shown secured to the upper edges of the siding and exteriorly thereof. Y The roof structure embodies a suitable number of longitudinally spaced carlines 5 which, according to the present invention, are of improved construction, they serve to seal and lock the roofing sections in position, and they are mounted on and secured to' carline supports of improved construction which are attached to the longitudinal frame. members 1. Each carline, according to the present invention, is composed ofsuitable metal and-embodiesa vertical or upright flange or web 6 which ispreferably flat, as

shown, and extends continuously between the carline supports, and a head or cap 7- formedon the upper edge of the flange or web extends continuously from end to end of the carline, this head or cap being formed with a pair of flanges 8 and 9 which serve to seal and lock the adjacent roofing sec--' tions. These flanges are arranged at opposite sides of the flange or web 6 andfdepend or extend downwardly from the head, such' flanges in the preferred form of'the invention extending at divergent angles and in directions downwardly and outwardly to form tapering channels 10 and 11 between them and the respective sides of the interposed web or flange 6. These flanges 8 and 9 are-preferably connected at the end of the carline by a cap 12 which is preferably formed integrally with the flanges, as shown, and these caps serve to close the ends of the channels 10 and 11. A suitable number of support. are mounted on and secured to the longitudinal frame members 1 to receive the ends of the carlines. Each support in the present instance has a flat section 13 to Seat upon the top of the rewhich he combining of the metal through openings'formed in the inner flange for this purpose.

side of the frame member and the outer side of the fascia board 4,'the upper outer it corner of the latter being preferably rabbeted to accommodate the flange 15 as shown in Fig. 2, and each support may be secured in in tie present instan'ce extend 14 for this purpose but these bolts do not extend through the fascia board or siding. The section 15 of the support is formed with an upstanding rib 17 which, when the carline is applied, enters the cavity which is'formed by the head 7, and this rib forms in effect a continuation of the vertical flange or web 6 of the carline,,this flange. or web being preferably interrupted at a point 'where the ends of the flange or Web 6 of the carline. abut against the inner end of the rib 17. The inner side of the support is provided with a socket to receive the flange or web 6 of the carline,/this socket in the present instance embodying which is formed integrally with and projects inwardly from the inner flange 14 of the support and is composed of opposed side members 18 which are connected at the bottom and form a slot or opening 19 between them into which the flange or web 6 of the carline may \be introduced, .and the carline may be fastened or secured in position by extending bolts or rivets through the socket and web, these parts being shown provided with apertures By securing the carline in this manner, spreading of the sides of the car is effectually prevented and collapsing of the sides of the car is also prevented, us

the end of the flange or web 6 of the carline abuts againstthe inner side of the support.

The roofing sections which are preferably of metal are applied in the form of plates which extend transversely across the roof osition by suitable bolts 16- a bracket and each plate occupies the space between I adjacent carlines. In the present instance,

each roofing section 20 has its edge bent vertically at'21 adjacent to the side of the vertical web or flange 6 of the respective carline, and this upturned edge is doubled to form a lip 22 which, when the carline is in position, lies closely against the inner side of thedepending flange 8 or 9 as the case may be. By doublingthe edge of the roofing section in this manner, the edge of the lip 22 possesses a certain degree of yield or resilience which enables it to hear closely and uniformly against vthe inner side of the respective depending flange, thereby producing a liquid and moisture-proof seal at this point and at the same time providing for expansion and contraction of the roofing sheet. The edges of each roofing section atthe caves of the roof may be down- I turned to form lips 23 which overlap the the entrance of water or moisture at these points and securing the sheets in position.

The application of each carline to its respective supports causes the dependingflanges thereon to descend upon the doubled edges of the two adjacent roofing sections, thereby forming joints which not only lock the roofing sections from displacement but also form sealed joints of a character which will prevent the entrance of water or moisture even though the water be driven against the joint with considerable force due to a rapid movement of the car. To prevent water or moisture from entering at the outer edge of the rib 17, it is also prefer able to provide a guard 24-which in the present'instance is formed as a part of and projects outwardly from the flange of the support and has divergent forward and rear edges 25 and26- which are provided with the slots 25 and 26 and secure the correspondingly flanged ends on the adjacent roofing sections, the inclination of the guard insurmg propgr drainage of water and prevent" ing the water from entering the car.

In order to maintain the various carlines in proper spaced relation and also to provide supports beneath the roof to sustain a weight imposed thereon, the carlines are preferably connected "by rigid spacers 'or purlins 29, each spacer in the present instance being composed of-a section of channel iron 30 having the web portion arranged uppermost and the flanges 31 in depending relation, the web portion being cut away for a suitable distance from each end of the channel iron and the flanges thereof are bent in opposite directions and at right angles to the length of the channel iron to formattaching lugs 32 which may be riveted or bolted to the vertical webs or flanges of the adjacent carlines. At each end of the car, the roofing may besecurcd by a car-line 33 wherein the vertical web or flange thereof will be secured to the siding 35 and the end frame member 2 by a suitable number of bolts 36, the depending flange atthe inner side of this carline cooperating with the doubled locking and sealing edge on the end roofing section as shown in Fig. 3, the

end fascia board 34 being rabbeted to ac commodate the vertical web of the carline and secured to the siding beneath the carline. I

The present invention also provides snnple and BflGCblVG means for supporting and securin the running board on the roof of the car, t e running board in the present instanceembodying a longitudinal section 37 and a; transverse section 38 which leads thereto from the ladder at one side of the saddle being thereby centered on the carline and rivets 4:1 serve to secure the saddle firmly to the carline. The opposite edges 42 of the saddle preferably project in opposite directions and provide means for securing the running board thereto, bolts 43 being employed for this purpose in the present instance. The'laterally extending section 38of the running board may be sup ported on the .two end carlines and in this instance the saddles-will be elongated to the proper extent.
