2 Claims.

This invention relatesto roofs for railway cars and more particularly to the roof construction and mechanism for securing the roof on the car.

One of the principal objects of the invention is the provision of a new and improved roof construction comprising a plurality of sheet metal plates having the carlines integral with the plates, together with reinforcing members for the carlines, the parts being so constructed and arranged as to form aroof that is cambered transversely of the car and that is adequately reinforced when in position on the car.

Another object of the invention is the provision of new and improved means forattaching a prefabricated roof structure in position on the longitudinal and transverse framing members of a railway car.

A further object of the invention is the provision of a new and improved car roof construction built up from sheet metal plates and that is comparatively inexpensive to fabricate, is light in weight and has a maximum resistance to stresses and distortion.

i Other and further objects and advantages of the invention willappear from the following devscription taken ,in connection with the accom- Y panying drawings, in which Fig. 1 is a top ,plan view of acar embodying the invention, with parts. broken away and parts in section;

Fig. 2 is a side elevation of the car showing the roof in position thereon, shown more or less diagrammatically and with parts broken away;

Fig. 3 is an end elevation of the upper portion of a car with the improved roof thereon;

Fig. 4 is an. exploded View in perspective of portions of the side wallsand the roof structure in position before being attached.

Fig. 5 is a fragmentary View showing a perspective of a portion of the roof structure and side frameor side plate member to which it is attached;

Fig. 6 is a vertical cross section of a portion of the roof and associated parts;

Fig. 7 is a longitudinal section of a portion of the roof and associated parts; n

Figs. 8, 9, 10 and 11 are views similar to Fig. v6, but showing modified forms of the means for attaching the roof to the side plates and side posts; and

Fig. 12 is a section on the line |2|2 of Fig. 1.

In the construction of the conventional railway car, the roof structure is built into the car as the structure is being fabricated. The roof in the conventional type of car comprises roof sheet or sheets and Vvcarlines that are Yseparate and are attached separately with the result that the fabricated structure is heavy, contains a-n unnecessary vamount of material and requires a considerable amount of time and labor in its construction.

The present invention seek-s to ysimplify the construction, lightenthe Weight', strengthen the structure, and materially reduce the cost of producing the fabricated unit.

Referring now to the drawings, the reference character designates generally a railway car having the under framing 2 supported by the trucks 3, Figs. land 2, the side walls 4, end walls 5, flooring 6. and roof section l.

In the construction of the car, the end and side walls, together with the corresponding sills and side plates are fabricated separately on horizontal sections by stretching the sheathing and welding together the frame and sheathing, after which these parts Vare assembled, as will presently appear.

The side wall or outer sheathing ll'of the car comprises a plurality of vertically extending strips or plates of sheet metal |3|,A see Figs. l and 12, welded together inY such a manner that Vthe outer surface of the side Wall will be smooth. The side posts are made integralwith the sheet metal strips, as shown more' clearly in Fig. 12. As shown, each sheet |3`| except the end sheets, has one edge'bent to Z-shape to form a side post 14|. The side post |4| 'is o-iset inwardly from the body of the sheet '|31 as at |38 to 'form a shallow recess for the reception lof the free edge of the adjacent plate. The recess is of such a depth that -when the straight edge of the adjacent plate is welded in position in the recess, the outer surfaces will be smooth or flush. The posts I4| are each preferably provided vwith a reinforcing angle lbar |42 which is nestedy in the inner angle of the side post and is welded thereto.

' The upper edge of the sheathing at each side of thecar, as well as the upper ends of the side posts MI, are rigidly attached to the inner r`side of the side plate |32, as by being welded thereto. The side plate |32 is angular, being roughly 4channel form with a downwardly extending flange |35.

The'channel portion ofthe plate .faces .outwardly Y and is provided with a vertical'web portionl |60 and with .an outwardly extending upper .flange |36, as shown more clearly in Fig.{6r of the drawings. Y l n f The top end plate 83 to which the end sheathing is attached is angular in cross section having the vertical portion |00, Fig. 7, the horizontal portion 95, seated on the end posts 8|, and an outwardly oiset vertical portion or flange I I. The upper edge is flanged outwardly as at ||0. Suitable gussets of any appropriate form are provided between'the vertical portion |00 and horizontal portion 95 of the end plate. In the form of the construction shown, gussets ||2 are preferably located above the intermediate end posts 8I. These gussets are U-shape in cross section and are triangular in side elevation and have their bases substantially the same width as the horizontal portion 95V of the end plate to which they are rigidly connected as by being welded thereto. The upper end or flange of the end plate extends horizontally over the upp er narrow end of the gusset plates and is welded Y thereto as shown in Fig. 7 of the drawings.

The roof construction comprises a plurality of carlines |62, Figs. 4 and 7, and a roof member |63. The roof member |63 comprises a plurality of sheet metal plates |64, Figs. 1, land 7, that extend transversely of the car and are connected together in a manner similar to the plates forming the outer sheathing at the sides of the car. In the form of the construction shown, however, these plates merely overlap, as shown in Fig. 7. Except at the ends of the car, each plate |64 has one of its side edges bent downwardly, as at |65, and flanged horizontally, as at 300 to form inte-V gral carlines angular in cross section as shown in Fig. 7. These roof sheets and integral carlines are so constructed that, when assembled, the roof isV cambered on its upper surface.

The depth of the vertical portion |65, Fig. 4, of each carline gradually decreases toward vits ends to partially compensate for the cambering of the roof so that the under surfaces of the carlines will be more nearly in a horizontal plane. YAs a result of this construction, the ilange portion 300 of each carline will be considerably widened at its ends, `as indicated at |66 in Fig. 7. This widened portion may be partially removed,

as shown in Fig. 7, or may be entirely removed, if.

desired.

The carlines are preferably reinforced by angle bars |61 which rest on the ilanges 300 of the carlines and are rigidlyY connected to both the vertical and horizontal portions of the respective carlines. The Vcarlines are of such length that vthey are positioned between the vertical portions '|60, Fig. 6 of the side plates |32 and are rigidly attached thereto as will presently appear. The sheets |64 extend over the outer flange |36 of the side' plates A|32 as shown more clearly in Fig. 6 Yof the drawings and are rigidly attached thereto. The carlines are further secured to the vertical .portion |60, Fig. 6 of the side plate by angle bars l|68 which extend across beneathrthe carline and the extension |66 as shown in Fig. 7 and are welded to the lower edge of the carlines and to lwith the adjacent sheet in the same mannerY as the sheetV forming the side wall and integral side posts described above and shown in Fig. 12.

The front and rear ends of the roofV member l |63 are extended forwardly and rearwardly over the upper flange I0 of the end plates 83 as shown "in lig.v 7, andare welded'thereto.

.bent inwardly beneath the carline SuitableV means are provided for rigidly attaching the side plate |32 to the side wall of the car. As shown in Fig. 6, the upper edges of the, side walls or sheathing 4 of the car lap the inner surface ofthe depending ilange |35 of the side plate and are welded thereto. In addition to this, the inner flange 2|4 of the reinforcing member |42 is extended upwardly alongside the web portion |60 of the side plate |32 and is rigidly connected thereto as by being welded.

In Figs. 8, 9, 10 and 11 are shown modified forms of attaching the roof to the side plate.

, In Fig. 10, a separate bracket 2|5 is employed, the upper end of which is bent inwardly to extend beneath the carline |62 and the body portion of which extends downwardly along the inner surface of the side plate |32 and downwardly along the inner surface of the side post |4| and is welded to the carline,- the side plate and the side post for holding the parts in assembled relation.

In Fig. 1l, the inner flange 2|0 of the side post 4| is extended upwardly along the inner face of the web portion |60 of the side plate |32 and is welded thereon. A separate bracket 2|6, bent to form an angle, has one flange beneath and secured to the carline |62 and its downwardly Yextending portion is in contact with the web portion |.60and welded thereto.

Y This is a division of our application Serial No. 133,632 filed on March 29, 1937.

It is thought from the foregoing, v taken in .connection with the accompanying drawings,

that the construction of ourdevice will be apparent to those skilled in the art and. that changes in size, shape, proportion or details may be made `without departing from the spirit and scope of .of the car and having the sheet metal extending over said flanges and rigidly connected thereto, one flange ofeach of said side posts extending upwardly across said side plate and bent to Vextend beneath the adjacent carline and rigidly connected to said plate and carline.

2. In a railway car having side posts at opposite sides of the car each including a web portion extending transversely ofthe car and a ange Aextending longitudinally ofthe car, siderplates supported by said side posts, said side platesv each having an outwardly extending flange at its upper 1 edge, said side posts each having a vertically disposed angle bar with one flange rigidly connectedto the'post web AandV the otherilange to the post flange for reinforcing the same, a roof unit supported on said side posts, said unit comprsing roof sheets Welded together and having integral carlines abutting said side plates at the sides of the car, said roof sheets extending outwardly over the anges of said side plates and rigidly connected therewith, said reinforcing bars for said side posts having iiange portions extending upwardly across said side plates and bent to extend beneath said carlines and rigidly connected to said Carlines and side plates.
