Claims. (01. 105-399) The invention relates to the construction of a body for land vehicles of the type used outstandingly for passenger trains but also used in similar form for freight cars, trucks, busses and trailers. More specifically, the invention relates to bodies of the indicated type representing a hollow-section beam structure having a transversely arched roof, the sides of which merge into the side walls.

Still more specifically, the invention relates to a preassembled roof unit and side walls connected in final assembly with each other for forming a body of the above-outlined general type.

Among the objects of the invention are simplification of the construction, reduction of the number of parts required, decrease of weight, and economies in the preassembling of the roof unit and the remainder of the body as Well as in the final assembly of these preassemblies with each other.

In broad scope, the invention contemplates a construction of the transversely arched roof along its lateral margins, and of the upper marginal portions of the side walls, which is such that roof and side walls can be easily connected with each other in final assembly without requiring the connecting tools to enter into the spaces between the roof members. In connection with this feature, the invention further contemplates the equipment of the roof with insulation and other parts and accessories which previously had to be installed, at least to some extent, after connecting roof and side walls.

The above outlined and further objects, advantages and features of the invention will be fully understood from the embodiments illustrated in the attached drawings and described hereinafter.

In the drawings,

Figure 10 is a fragmentary section through the meeting portions of roof and side wall, the section being taken approximately along line l0l 0 of Figure 9 and the outer roof sheathing being omitted.

This application is in part a further development of the disclosure in applicants copending application Serial No. 782,004, entitled Roof and Side Wall Connection for Railway Cars and Similar Vehicles, filed October 24, 1947. The general construction and the procedure of assembly illustrated in Figures 1 to '7 are also dis-v closed in applicants simultaneously filed application Serial No. 38,728, entitled Body for Land Vehicles, Especially Railway Cars, and Method of its Assembly, the claims of which are, however, directed to difierent features than the claims of this application. Certain features of this application are also shown in the simultaneously filed application Serial No. 38,726 of Gladeon M. Barnes, Charles L. Fike and the present inventor, entitled Roof for Land Vehi.- cles, Especially Railway Cars, and Method of Making the Same.

Following a known pattern, the railway car body illustrated in Figures 1 through 7 is built up of the following preassembled units: an underframe unit U, two side wall units S, a vestibule and a non-vestibule end wall unit V and NV, the former combined with end door posts P, and a roof unit R. The underframe unit U and the end wallunits V and NV are merely diagrammatically indicated in the drawing because their construction may be of known design. The underframe unit U may be preassembled with the side wall units S, the posts P and sometimes the end wall units V and NV, to form a larger unit, to which the roof unit R, is then added in final assembly.

Each side wall unit S comprises a plurality of longitudinally spaced vertical posts i5 interconnected by a bottom sill orchard it (Figure '7), a window sill or chord H, a Window header or chord !8, dead light panels is between and below the window openings W, and a shear panel (Figure 2) between bottom sill i tend Window sill H. The upper ends of the posts [5 prior to their connection with the roof project freely beyond the window header l8 and are provided on the inside with gusset plates 2i constituting part of the final assembly means between side wall and roof. The end regions of each side wall unit are provided with vertically reinforced shear webs 22.

The posts I5 are of channel-section and are arranged in pairs so that their open sides face each other. The outer walls 2-3 of the posts are secured by spot welding to the dead lig-ht panels l3, the shear panel 20 and the belt rail 24. The aforesaid gussets 2| are secured by spot welding to the inner walls of the posts. The window sill H and the window header l8 comprise short channel- section members 26 and 21, respectively. The members 1-6 are interconnected on the outside by the dead light panels i9, the belt rail 24, and the members 2"! are connected on the outside by the dead light panels i 9 and on the inside by gusset plates '28, the latter extending between anda short distance beyond two adjacent posts. The dead light panels I!) are supplemented at top and bottom by panel strips 29- and 30 which are secured to the members 26, 2'! and to the dead light panel l9 forming with the latter'the margins of the window openings W.

The underframe structure U comprises a transversely reinforced shear panel 3! and side sills 32 connected in final assembly with the sills iii of the side walls 5, and mostly comprises, in addition, a center sill, cross bearers'and bolster beams which are not shown.

The roof unit R, comprises a continuous upwardly facing channel-section sleeper or chord structuref33 on each side, longitudinally spaced Z 'secti o n carlines 34 having their ends secured in the sleepers 33, a longitudinally corrugated roof skin or sheathing 35 secured to the outer arms 35 of the carlines 34 and, on each side in downward extension of the roof skin, a skirt or letterboard 3'! reinforced along its lower margin by a molding 38. The roofis further reinforced by longitudinalpurlines -39 secured to the carlines 34 and the adjoining portions of; the roof sheathing 35; The lateralside portions 40 (Figure 7) of the roof are strongly arched and, without abrupt change of direction, merge into the side walls and into the nearly horizontal, gently arched middle portion 41 of the roof.

The roof sleepers 33 have an outer wall 42, a bottom wall 43 and an inner wall 44 which is wider than the outer walland reinforced along its upper margin by a beading 45. The letterboard. or skirt 3'! issecured to the outside of sleeper wall 42 and projects upwardly beyond it at 46 so that the top margin of the letterboardis approximately on the same level as the top margin of the inner sleeper wall 44. This upwardly projecting portion $6 of the letterboard is secured by spot welding to the lower marginal portion of the roof sheathing 35 (Figures 3 and 4).

The roof unit U, before its connection with the side walls S, maybe provided with insulation Sinai terial indicated at 41 in Figure '7. This insulation is held in the compartments formed by the carlines 3d, the outer roof sheathing 35 and the sleepers 33, and may extend all the way to the bottom Wall 43 of the latter. As will become apparent later on, the insulation 4? and other equipment and accessories (not shown), which may be preassembled with the roof unit, do not interfere with the making of the final connections between roof and side walls, on account of the novel construction and arrangement of the mating parts and of the final joints.

In final assembly, the roof unit R is slid telescoping-1y over the side wall units S which, as indicated before, previously may have been united with underframe, end walls and posts U, NV, V and P, whereupon the gussets 2! on the posts l5 are secured by plug welding to the inner walls 44 of the roof chords or sleepers 33, and the shirts or letterboards 37 of the roof unit R together with the moldings 38 are secured to. the outer walls 23 of posts i5 and the outer walls of window headers N3 of the side wall units S. For the purpose of making the plug welds, the gussets 2| are provided from the outset with holes lS along their upper margins.

The connection betweenthe upper margins of the gussets 2! and the roof sleepers 33 also can be effected by other means which do not require the entry of tools into the interior of the roof sleepers, a requirement which would prevent the com plete equipment of the roof with insulation. etc. It would also be feasible, without impairing the placing of insulation, etc, to preassemble the gussets with the sleepers and connect them in final assembly with the inner walls of the posts by electric spot welding. However, the illustrated procedure is preferred because it avoids difficulties in regard to lineeup of posts, gussets and carlines which are to be expected when gussets and posts are preassembled with different units.

The spot welding of letterboards 3'! with molding 38 to the outer walls 23 of the posts and to the outside of the window headers 58 can be effected easily by welding tools extending through the window openings Wwithout having the welding tools enter the space of the roof above the roof sleepers.

In the embodiment illustrated in Figures 8 and 9, the roof unit R has on each side, only one side being shown, a sleeper structure 50, transverse carlines 5i, and a roof sheathing 52 ex tended downwardly beyond the sleeper by skirt portion 53 and reinforced by an inner shear panel 54 and by a molding rail 55. The sleeper struc ture 59 comprises an upwardly facing channelsection 56 to the bottom wall 5! of which an angle-section rail 53 is secured by its one arm 59 while its other arm 6! extends downwardly and is arranged in the same plane as the inner wall iii of the channel-section 55. The outer wall 62 of the channel is secured to the panel 54 which, similarly to the letterboard of the previous embodiment, extends at 63 beyond the channel 5%. Secured to the inner wall 6| of channel 56 and arm 60 of angle-section rail 58 is a web 64 which, in addition, is secured to the carlines 5i and balances the upwardly projecting portion 33 of panel 54.

As in the previous embodiment, this roof unit R may be provided with insulation and other accessories and equipment prior to its assembly with the side walls S.

The side wall units S comprise posts 65, the lower portions of which may be interconnected in similar manner as that shown in the previous embodiment. In their upper regions, yet spaced from their upper ends, the posts 65 are interconnected by a window header structure 66 consisting of channel-section members 61 extending from post to post and a continuous inner metal band 68 secured to the inner walls of the posts and to the inner wall 69 of the members 61. Triangular gussets are secured to the inner walls of the posts 65 at the upper ends thereof and have inwardly directed flanges H along their upper margins. The dimensions are such that the posts 65 with gussets ID of the side wall units S fit telescopingly between panels 54 and arms 60 of the roof unit R and that flanges H of gussets 10 present a support for the roof unit R.

For final connection between roof unit R and side walls S, the downwardly depending skirt 53, 54 of the roof unit, together with the molding 55, is secured to the outer walls of posts 65 and header members 61, and the portions of the gussets 10 projecting longitudinally beyond the posts are secured by spot welding at 12 to arms 60 and the lower portions of strips 64 of the roof sleepers 50. Here, as in the preceding embodiment, all these final connections can be made by tools which do not require reaching into the interior of the roof above the bottom wall of the sleepers and consequently require no consideration in providing the roof with insulation, accessories and equipment.

In both embodiments the construction is simplified, as compared with known construc-' tions, inasmuch as there is merely a sleeper construction along the lower margins of the roof rails and as the upper ends of the posts above the window header have no longitudinal connection prior to their assembly with the roof. In the embodiment shown in Figures 1 to '7, the number of elements in the regions where roof and side walls meet is reduced to the very minimum by the omission of the corrugated sheathing of the skirt, by the adaptation of the skirts as letterboards on account of their smooth exposed surfaces, by the ommission of top chords on the side wall units and by the reduction of each roof sleeper to one single element. This simplification is achieved by transferring the functions of the omitted elements to the remaining modified elements.

The illustrated structures consist throughout of sheet metal elements, preferably of austenitic stainless steel of the high tensile variety. In most cases these elements are connected with each other by electric spot or seam welding. These welds are indicated throughout the drawings by small asterisks and, in the case of crosssections, by dots, and require no further description. The departure in the first embodiment from spot welding for the joinder between gussets 2| and sleepers 33, and the importance of such departure, are outlined in the description of Figures 1 to 7.

The invention is not restricted to the illustrated and described embodiments but is subject to further modifications and adaptations which, for instance, may be based on differences in car design and dimensions, available manufacturing facilities, materials to be used and on other factors.
