` 11 Claims. (Cl. 10S-5.4)

My invention relates to metal car roofs. One of its principal objectsis to conform the upper surface of the roof as closely as practicable to the established tunnel clearance outline and at the same time make the roof as .thin as practicable so as to give the car a maximum loading capacity. Another principal object is to adapt the carline spacing to suit the requirements of the lading. Another object is to provide for the use of separate carline members in lieu of an integral'or continuous carline. Another object is to facilitate the work of building and assembling the car roof and to provide for the use of preassembled units Winch may be designed to better advantage than roofs `wherein the sheets and carlines are con-` tinuous from side plate to side plate of the car. The invention consists in the construction hereinafter described and claimed and particularly in the parts hereinafter described and claimed.

Fig. 11 is a section similar to Fig. 5 through the eaves portion of the modified roof construction;

Fig. 12 is a section similar to Fig. 6 through said modified roof construction. The present roof comprises series of units made up of sheets and carline members, which units are united together and to the side plates of the car. There are two types of units hereinafter :referred to as the side units A and the ridge units B, respectively. As shown in Fig. 1,l there are four side units and two ridge units, each roof unit extending one-half the length of the roof.

Each of the side units A comprises a roof sheet I with one or more carline members 2 secured to the under side thereof, as by welding. The eaves 5 end of the roof sheet'of each side unit and its carline members are anged downwardly, as at 3,.and secured i'latwise, as by rivets 4, to the outer face of an upstanding leg of a side plate 5 of the car. As shown in Fig. 9, the remote ends 1o of/adjacent side sheets are flanged downwardly' and secured flatwise, as by rivets E, to the outer facesof the end plates 'I of the car. As shown in Fig. 7, the adjacent margins of adjacent side sheets I are secured together and to the adjacent 15 carline members 2 of one ofl said sheets, preferably by welds 8. The inner end margin of the roof sheet of each side unit isbent downwardly to form a downturned fiange Sadapted to be secured to. the longitudinal ,margin of an adjacent ridge 20 unit B.

The roof sheetv I0 of each ridge unit B is a flat rectangular horizontally disposed sheet with downturned flanges I I 'along its longitudinal margins. `Each ridge sheet I0 has one or more 25 carline members yI2 secured to the undersidel thereof, as by welding. Adjacent margins of adjacent ridge sheets I Il are secured together and lto the adjacent carline member I2 of one sheet, preferably by a transverse weld I3 that joins the 30 side sheet welds 8 to form a continuous transverse weld. The remote ends of adjacent ridge sheets are flanged downwardly and secured by 'the rows of rivets 6 to the end plates of the car.

The longitudinal anges II of the ridge sheets 35 I0 abut atwise against the downturned anges 9 of the side sheets I and are secured thereto preferably by longitudinal, lines of welds I4 and I5`at the top and bottom thereof, thereby forming rigid longitudinal seams that function as 40 purlines. l,

The carline members I2 illustrated iny Fig. 8 are channel-shaped and extend, transversely of the car, from one longitudinal downturned flange II of the ridge sheet I0 to the other longitudinal 45 downturned iiange II thereof. Such carline member is welded to the under side of the ridge roof sheet by welds I6 that extend transversely of the roof and its ends are secured to the 50 anges II by vertical lines of welds I1. 'Ihe carline members 2 ofthe side sheets I are similarly welded, as at I8 and I9, at their tops and inner ends, respectively. Obviously, the carline members may be of any other4 suitable cross- 55 sectional shape, or in the form of ribs pressed in the roof sheets.

The units hereinbefore described may be made of various sizes and may include one "or more v carline members for each unit, as determined by convenience of manufacture, shipment and assembly. In their assembled relation, the carline members of transversely alined units may be disposed either in alineme'nt with one another, as shown in Fig. 1, or offset longitudinally of the car, as shown in Fig. 2. Incase of such offsetting, it is preferable, as shown in Fig. 12, to incorporate a reinforcing member 20 in the longitudinal seams between the ridge sheets and the side sheets in order to coordinate the side carline members and theridge carline members into a simple beam or structure with ends resting on the side plates, as when the carline members are alined.

The runningboard 2l consists of a plurality olf spaced parallel boards that rest atwise upon the top of the ridge sheet with the spaces between said boards lled with a waterproof compound 22. The running board is' secured to the roof preferably lby inverted channel shaped straps 23 that straddle said board and have outstanding 'base flanges that are welded vto the tops of the ridge sheets. As shown in Fig. 7, the top of the running board is channeled, as at 24, from side to side to bring the tops of the straps flush with the upper surface of the running board.

By making the ridge units separate from the side units, the designer is aiorded great latitide in the shape and dimensions of the carline members ofthe different units as wellas in the spac.-

ing of such carline members. Thus, although it is customary to increase the depth of carlines from eaves to ridge, it is practicable in my construction to'avoid such increase of depth and to make the lower face of the carline member of the r ge unit horizontal' and parallel with the horizontal roof sheet. In fact, by using carlines of suitable cross-section and in sufcient number, it is practicable to make a roof of less depth at the ridge than has heretofore been practicable with inside carlines.

It is noted that the ridge' sheets l are flat and horizontal and that the running board 2| is secured fiatwise thereon. By this arrangement, the ridge sheets may be placed at such position that the upper surface of the running board lies immediately below the established clearance line for clearance outline C; and, as shown in Fig. 4, the

side sheets may extend from this point to the side plate in two straight reachesl with a break be- .tween them to correspond with the established clearance outline. yThus, the cl'ose approxima- -tion of the upper surface of the roof to the clearance outline from side plate to side plate, coupled with the thinness `or small depth of the roof structure, especially when the carline members are spaced to accommodate special lading, increase the capacity of they car and make it practicable to utilize the full capacity of the car for lading. As shown in Fig. .10, the side sheets may extend in single straight stretches from the ridge sheets to the side plates, thereby eliminating press work in the manufacture of such sheets.

n It is an advantage of my construction that the same side sheets may be used with ridge sheets of different widths so as to meet the requirements of cars of different widths. Y

It is noted as a great advantage of my invention that'it permits the ridge carline members to be spaced at such distances apart as may be best adapted for the lading.
