`, understood that the invention is not limited tothe exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art- In said drawings: Figure 1 is a side elevational view of approximatelyr one half of a box car constructed in accordance with this invention. Fig. 2 is a vertical longitudinal sectional view showing the inner face of the side wall illustrated in Fig. l. Fig. 3 is a transvers'evertical sectional view.` .the left handfside'of said figure showing a section taken at the side door and the right hand side of said figure showing a section taken at a point intermediate the side door and end of the car.' Fig. 4 is an enlarged fragmentary elevational -view illustrating the details of construction at the lower corner of onef'of the side doors. Fi 5 is a t e lane vertical sectional view taken on the plane 4, being also an enlargement of the sectlon shown at the lower left hand corner of Fig. 3, for better illustratin the construction at the side door. Fig-g is a detail sectional view similar to that shown in Fig. 6," but being substantially an enlargement of the section shown atthe lower right hand corner of Fig. 3, for better illustrating the construction between the side doors and the car ends.

The object of this invention is to provide a light, but substantial, all-metal, car wall and to soidesign the same. tha-t it may be manufactured at a less cost than Walls of the same capacity heretofore built.

To this end the invention comprises a-reinforcing member for the wall, said reinforcing memberextending continuously be,-

portions fixed to the side plate and to the sheathing plates and posts in such manner as to permit of the omission of some of the sheathing plates and posts, for forming'the door opening without materially affecting the weight sustaining capacity of the wall, said sheathin plates serving as splice plates for' connecting said remforcing member to said posts.

It further providesthat the floor sheets be connected with the side connecting member and with adjacent portions of the sheathing plates in such manner as to au posite end ,ment the weight sustaining capacity of said wall members.

Itfurther provides that the floor plates, at the door openings, be so formed and connected to the side connectin member and to the intermediate portion oy the continuous reinforcing member, above referred to, as to reinforce said members, and at the same time provide 'an ,appropriate door sill covering said members.

Referring to the drawings in which is illustrated the preferred embodiment of the invention, the numeral 1 indicates the center sills, 2 the cross bearers and 2 the holsters of the underframe structure.

The o posite side walls of the car being identicalp one only will be described in detail and the description thereof. will obviously apply to both.

The si e connecting member comprises a vertically disposed plate 3,v extending lengthwise of the car having its upper edge substantially in the plane of the under-surface of the floor plates 4, and a reinforcing angle 5 disposed with one of its flanges upstanding and fixed 'to .the inner surface of the plate 3, and withits other flange projecting inwardly at the; lower edge of said Ifirst mentioned flange and in the plane of the lower edge of theplate 3. The comound side connecting member. thus formed 1s of L-shape in cross section havin its shorter yleg projecting inwardly an longer leg upstanding.

The floor plates 4 exten'd from side to side of the ,car resting upon the upper-surfaces of the center sills 1 and transverse members 2 and 2, and'has its opposite longitudinal edges flanged downwardly, as at 6, and fixed lto the ,inner surface of the plate 3 ofthe itsl to said `iside plate and side connecting member along the upper edge thereof, throughout. the length of the car, except as follows: Adjacenteach ofthe side posts 7, the Hange 6,- and apart of the horizontal portion of the oor plate, is cutforming a recess 8, adaptedto receive the posts; at the side door the Hoor plate is extended across the upper edge of the plate 3, of the sideeonnecting member as at 9, and is 'anged downwardly across the `outersurface of said plate, as at 10, said down-v turned ange having its lower edge'in the i same plane with the loweredge of the plate 3. The flange l0 extends longitudinally of the car from one of the door posts to thev other. The flange 6 is cut away adjacent the j door posts, as at 6a for the passage of a tension member as`16 hereinafter described.

The posts 7 may be of any desired cross section, but are illustrated as comprising vrolled angles having one of their lianges as 7a fixed, by its iiat outer surface, to the v inner face of the plate l3 andhaving its other flange 7b extending inwardly. The

lowerends of each ofthe yposts are oset as at 11 for accommodating the upstanding flange of the reinforcing angle 5 of the side connecting member, and said offset portions are ixed to said angle by through rivets, as at 12. a

The transverse members 2` of the under-l frame are preferably secured to the posts 7, as at 13, said posts serving as angle brackets for connecting said transverse members ,to

'the side connecting member.

The sheathing plate or plates `as* 'are securely riveted directly to the 'outer faces of the flangesa of the posts 7, having their lower longitudinal edges oset at the upper edge of the plate 3 and'lapping theouter face of said plate and being riveted thereto p by through rivets some of which extend through the upstanding flange of the angle 5, others through said flange andthrough `the posts 7 and others through the flange 6 of the floor plate. The upper longitudinal edge of the sheathing plate 14 ,is ixed to the inner vertical surface of the side plate 15.

A continuous .tension bar as 16 extendsthe angle 5.

from the side plate., atv one of the transom posts 7c, above the car bolster, at one end of the car, to the side plate. at a correspondinglocation near the oppositeend of the car, having its intermediate :portion depressed and extending beneath the floor plate at the door opening. The tensionvbar 16' is preferably of uniform cross section having one of its flat faces resting against the inner-sur face of the sheathing plates and being fixed thereto throughout its length, except atthe door where said sheathing vplates are omitted. At this point the tension bar engages the inner alined surface of the plate 3 of thev side connecting member 2 and is xed thereto.

At Toppositewsides offthe door openings the end portions of the tension bar extend diagonally upwardto the iside plate, said diagonally' disposed yportions intersecting the posts 7 -and said posts'being formed with suitable recesses 16,a Fig. 3 adapted to a`c commodate said tension bar so asl to provide plates 14. The s connecting plates rigidly 'connecting said tension bar to said. osts.' Likewise. at the ends of'thevtension arthei'plates 14 being fixed to the posts v7and to the side plate, and'to the tension. bar, form gusset plates rigidly connecting the ends ofthe tension bar tothe side plate and to said posts 7. Supplemental gusset plates 17 are fixed to the ends of the tension bar, and to the adjacent posts,` and ttl-theA side plate. r[he sheathing .plates serve also as means for con;v ne'cting the posts.7,j7,fthe side plate and the side cnnecting member.

d Supporting braces or `tension members as 18 extend' from adjacent the upper ends of the tension bar 16 downwardly to the ends of the car for supporting the end sills, said braces beingfixed to the sheathing plates, and to the side plate, and to the supplemental gussetvv plates, similarly as are the earning 'pines mlbein 'exea te the posts 7 and to' the tension ar, form van evenv surface for the attachment of the sheathing endsv of thebar 16, said gusset forming a v bond' between the adjacent ends of said bar 16 and v'braces '18 for equalizing theirvv respective stresses upon the upper ends of the posts 7d. The side plate 15 yextending be- Atween Eandbeing lixed to the adjacent ends of the bar lvand braces 18 and to the posts, serve 'as means for reinforcing the connection between said-bar and braces and said osts. l 1

rlheposts 7 at opposite sides of vthe door are offset at their lower ends at the floor `level to accommodate the bar 16, and to form a shoulder as 19 under which the bar is arranged to engage. Owing to the greater thickness of the tension member 16,' a filler block 20 is interposed between the lower end ofthe post and the'upstanding` flange of lt will be noted that the downeturned flange .of the floor sheet 4, being disposed flanges of the floor sheets, and by the lower portions of the sheathing plates. @bviously the roof structure, forming no particular part of this invention, but beingxed to the Vertical posts fixed to door opening side plate, adds materially to the strength of said side plate as a compression member.
