7 claims.

railroads of the types commonly known as double sheath steel underframe box .cars and single sheath box cars. All of these cars are provided with a substantial metal underframe including channel side sills and sheet metal ends and which are in sound condition and suitable-for carrying present day loads. the majority of instances are in bad condition with the wood sheathing shrunkand otherwise impaired due to the driving of nails therethrough for the purposeof fastening lading or abuse resulting from the use of pinch bars in forcing the side doors into closed position. Practically al1- of said cars are also so designed as to afford only aproximately 8', 6" of inside width, which is less than that now recommended under the present A. R. A. rules.

Railroad oflicals are, therefore, confronted with a serious problem in determining whether or not to try to keep in repair said present wood sheathed cars by renewing the wood sheathing with the attendant' expense and frequently rejcurring repair bills sure to follow or to provid'ean all metal car with steel sheathing possessing greater strength,` rigidity and freedom from leakage 'in line with the constantly increasing demand for all metal cars on account of their greater durability, strength and lesser A wood sheathed house cars while reutilizing the voriginal steel underframes and sheet metal ends so as to provide. a more durable and eiiicient car better adapted to present day conditions.

-Another object of the invention is to provide,

Y in a repair constructionfforwood sheathed house cars, a .metal side wall construction that` may Abe lccmbined with the 'original steel underframe inreplacement of the original wood sheathed walls, in such manner as to V,obtain agreater inside width without necessitating'any change or relocation of the side sills of the underframe.

More specically, objects of the invention are The side walls, however, in

to provide allmetal side wall repair constructions of the type indicated in the two preceding objects of invention which may be assembled as a unit at the manufacturing plant and applied to the original car underframesthere or at shops of the railroad car owners and to so arrange and construct the unit repair side walls that, in the a minimum number of new rivet holes will be required in the side sills to eiect the attachment.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawings forming a part of this specication, Figure 1 is a side elevational view of approximately one half of a box or house car showing one embodiment of the improvements incorporated therein and as specifically applied to aA house car of original wood, double sheathed type. In this view, certain portions are broken out in order to better accommodate the g-ure on the sheet. Figure 2 is an enlarged, vertical, sectional view, parts being broken away, corresponding to the section line 2-2 of Figure 1. Figure 3 is a horizontal, enlarged, detail sectional view, corresponding to the section line 3-3 of Figure 1. AFigures 4 5 and 6l are vertical sectional views attachment thereof to the original underframes,

similarto the lower portion of Figure 2 and illustrating three different modifications in the repair side wall constructions and attachments to the side sills. Figure 7 is a front, elevational view of the arrangement shown in Figure 6, the latter sectional view corresponding to the section line 6 6 of Figure 7. Figure 8 is a View similar to Figures 4, 5 and 6, illustrating a' still further embodiment of the invention.

' Figure 9l is a vertical sectional view illustrative of the present construction of many thousands of single sheathv wood box cars now owned by the railroads. Figure 10 is a. similar, vertical, sectional view taken through the sidewall of the same type of car as converted to include one formvof the present improvements. And Figure 11 is a side elevational view of the construction at the lower end of the side wall arrangement shown in Figure 10.

In said drawings, only approximately one half of a side of ,a car has been illustrated in-Figure 1,

but 'as will be understood by those skilled in the art, the remaining portion of the same side of the car will be complementary of that'illustrated and the 'opposite side of the-car will be a duplicate-thereof.

Referring iirst to the construction illustrated in Figures 1, 2 and 3, one of the channel side sills of the steel underframe of the original car is indicated at I and one of the original metal end walls is indicated at I I. The wood double sheathed cars, in their original condition (not illustrated) are provided with wood side posts, outer wood sheathing, inner wood lining and Wood side plates. In carrying out the present invention, all of these parts are dispensed with except that the inner wood lining is either replaced or a new one substituted therefor.

In carrying out the repair construction, a plurality of intermediate Z-bar side posts I2 are ern` ployed arranged as best illustrated in Figure 3, that is, with the webs of the Z-bar posts extending perpendicular tothe plane of the side wall. At their upper ends, the posts I2 are attached to a new Z-bar side plate I3, the web of which is disposed horizontally as indicated at II3, the outer flange depending, as indicated at 2I3, and the innerflange extended upwardly as indicated at 3I3. The attachment between each post I2 and side plate is preferably effected by two angle clips III-I4 each of which has one flange thereof riveted to the web of the post and its other ange riveted to the web of the side plate, one clip being disposed on each side of the side post web.

At their bottom ends, each post I2 isrigidly supported and connected to the side sill In, by the following arrangement. In line with each post is provided a bracket I5, preferably nin the form of a casting. Saidbracket is formed with two oppositely extending inner flanges I5a-I5a' which are directly riveted to the web of .the side sill'fIll. The bracket I5 is additionally formed with an outwardly extended, centrally disposed vertical ange I5b alined with the web of the post I2. Connection between the post andbracket is effected through the medium of two vertically extending plates I 6--I6, each of which is con' nected to the web of' the post and the bracket ange I5b by a plurality of rivets I'I, as shown. As clear from Figures 1 and 3, said rivets I'I are in double shear. With the construction so far described, it will be seen that the number of new rivet holes required in each side sill is kept to'a minimum, the same corresponding to only those rivets requiredsfor attaching the brackets I5.

The door posts, one of which is indicated at I8, will also preferably be of Z-bar type but with the web. thereof arranged parallel to the plane of the side wall. Attachment at the lower end with the side sill is effected preferably through a plurality of angle plates ISI-I9 and 20, the former being rivetedK to the inturned iiange of the Z and side sill and the plate 20 to the side sill and out-turned flange of the Z post. At its upper end, each door post I8 will be attached to the side plate, which extends continuously from end to end of the car,` in the same manner as'the intermediate posts I2, that is, 4by angle plates or clips I4I4.

The new metal sheathing which replaces the original'wood sheathing, preferably consists of a plurality of rectangular panels 2I and 2|. and, together, completing the closure from each door post to the corresponding corner of the car. The end panel 2 Ia will be lapped under the usual vertical side flange III of the end wall and the connection reinforced by an interior plate 22, all the parts being suitably rigidly connected by the vertical series of rivets 23-23. The panel 2I adjacent the door opening has its adjacent vertical edge lapped over the web of the door post I4 and riveted thereto by the vertical series Of rivets 24.

The panels are preferably lapped in line with the outer flange of each intermediate post I2, as best shown in Figure 3, and the lapped flanges riveted to the post flange as by the vertical series of rivets 25. Along their upper edges, the sheet metal panels 2I-2Ia are lapped under the depending ange 2I3 of the side plate and riveted thereto by the horizontal series of rivets 26.

'The lower edges of the sheathing panels are connected to the side sill of the vunderframe by a v,longitudinally extending, preferably formed angle plate 2l best shown in Figure 2, said plate 2'I extending from door post I8 to the corresponding end of the car. Said angle plate 21 has an outer upstanding flange lapped under the lower margins of the sheet metal panels and connected thereto by a horizontally extending series of rivets 28. The other horizontal and wider flange of theangle plate 21 is extended inwardly beneath the lower ends of the posts vI2 and supported on the upper ange 29l of the side sill and riveted thereto as by the horizontally extending series of rivets 30. Where the angle plate 2'I passes beneath each post I2, the angle plate 21 will be suitably notched out, as indicated at 3 I, to accommodate the post and bracket connecting plates I6. Further, each post I2 will be notched out or coped, as indicated at 32 in Figure 2, so as to clear the upstanding flange of the bottom angle plate 2'I and thus avoid the necessity of offsetting the outer ange of the post I2, which would otherwise be necessary in order to maintain the sheathing in the one vertical plane.

The inner wood lining 40 is applied to the inner sides of the posts and the means of attaching the same in place is afforded by vertical nailing strips 33 which are supported from the panel sheets by angle plates 34-34 riveted thereto, the nailing strips in turn being bolted to the plates 34 as by the bolts 35. Preferably, the lining will termi nate somewhat above the floor 36 and shedding cleats 31 interposed near the floor line between the 'several pairs of posts.

In carrying out the invention, the repair side wall may be shipped knocked down and the parts applied in any desired manner but, preferably, the improved repair side wall will be fabricated and shipped as a unit, that is, with the side plate I3, posts I2, door posts I8, sheathing panels, the two lower angle plates 21 at opposite sides of the door opening, and brackets I5 all riveted and connected together so that the unit may be applied directly to the underframe of the original car 'after the latter has had all of its superstructure, with the exception of the end walls, removed. As will be understood, the necessary additional rivet holes will have been provided in the side flanges of the end walls for the end panels and in the side sills for connection of plates 21, door posts and post attaching brackets I5.

When the car is converted in themanner described, it is evident that the side walls become true load-carrying girders with tension exerted between the posts and the side sills. By providing the direct type of connection described between the bottoms of the posts and the side sills through the brackets I5 and plates IG, these tension stresses are very eectively resisted in direct vertical pulls, without imposing any appreciable stresses in the bottom angle plates 2l. Attention is also directed to the fact that corrosion will be effectively resisted along the lover edge of the side wall by the relatively thick 0r heavy bottom plates 2'I.l Any moisture that may prevented from coming in contact with the relatively thin side wall sheathing by the upstanding flanges lof the plates 21, thus insuring longer life of the all metal side wall arrangement.

Referring next to the construction in Figure 4,`

the side sill I is there shown as having a post attaching casting I I riveted to the sill as in the case to the Vplane of the side sill and' adapted to be riveted to the inner ange of the post I I2 by the series of rivets I I1. The bottom attaching member |21 is similar to the plate 21 of the rst described form and is secured to the top flange of the sill in the same manner as by the rivets |30. In the Figure 4 construction, the post I I2 is not coped at its bottom but, on the contrary. the outer flange of the Z is laterally inwardly offset as indicated at I I2a and is connected to the upstanding fiange of the bott/om plate |21 and lower edge of the sheathing by the rivet |28. The remainder of the side Wall construction with respect to the attachment of the posts and sheathing to the side plate may be of the same character as that previously described.

In the Figure 4 construction, it will be noted that the inner wood lining |40 is located farther out from the center line of the car than the lining 40 of the first described construction, thusproviding for a greater inside width of the/car when this is desired. As will be understood, the posts and lining of the rst described form might also be set`outwardly', if desired, to accomplish the same result. y

In the Figure 5 arrangement, the post attaching bracket or casting 2I5 is, also secured to the side sill III vbut in thissinstancethe attaching bracket is provided with a pair of upstanding flanges 2|6 arranged perpendicular to the. plane of the side wall and adapted to straddle and embrace the web of the post 2 I2 to which it is riveted as by the rivets 2|1. Inth'e Figure 5 arrangement, the plate or bottom attaching member 221 is generally similar to'the bottom plates 21 and |21, previously described, but is providedl with an additional upwardly offset 'section 4I. In some instances, it is desirable to use thinner floor boards than those originally used on the car and as shown in Figures 2 and 4, for instance, without materially changing the height of the floor from the rails.. With the Figure 5 construction of plate 221, the floor boards 23B may be' of lesser thickness to accomplish the result indicated, the same being supported above the side sills by utilizing the integrally formed offset 4| referred to. In both of the Figures 4 and- 5 constructions, it will be understood that the plates |21 and 221 are suitably apertured for passage therethrough of the bracket flanges IIB and 2I6 respectively, and

further, each of the brackets |I5 `and 2|5 is formed with'horizontal supporting anges riveted to the horizontal legs of the plates |21 and 221 as by the rivets 42-42.

Referring next to the construction illustrated in Figures 6 and 1, the attachment for the lower end of each of the posts 3I2 is effected through a specially formed attaching bracket or casting 3I5 riveted as before to the side sill I0, as indicated. In this arrangement, the attaching bracket is formed with a narrow shoulder or'ledge 3I5 flush with the upper flange of the side sill and an upwardly extending section 3|5b outwardly thereof. AThe side wall bottom attaching member 321 is formed to correspond with the contour of the bracket 3 I 5 and may be said to be of approximately W-shape. The bracket 3|5 is provided with a pair of upstanding integral flanges 3|6 similar to those of the'bracket shown in Figure 5 and which are secured to the web of the Z bar post 3 I 2 in the same manner. In the Figures 6 and '1 construction, the outer flange of the post 3I2 is coped, asindicated at 332 to clear the upstanding outer flange of the bottom connecting plate 321. With the W type of plate 321, it will be seen that the lapped joint, between the sheathing and upstanding flange of the plate 321 is located above the level of the flooring 336 so that there is even less danger of corroding the sheathing than in the previously described forms since it is practically impossible for any moisture to reach the sheathing from the inside of the car.

Referring next to the modification shown in Figure 8, the attaching bracket or casting 4|5 is similar to that of Figure 5 and attached to the Z-bar post 4| 2 in the same manner. The post in this instance is shown coped as indicated at 432. In this construction, the bottom member 421 of the side wall structure is of angular cross section and eachwill extend from door post to corner post as in the case of the previously described forms. The plate 421, however, is not extended over or connected to the side sill I0 but has the inner edge of its bottom horizontal flangev located somewhat outside of the plane of the' side sill web. The plate 421 is connected tothe brackets 4|5 by rivets 442, as clearly shown;

To provide suitable attachment for the floor boards 43B, a separate longitudinally extending plate 44| is employed, the same being riveted to the upper flange of the side sill and extended inwardly thereof and towhi'ch the boards may be attached as by the bolts 443. The outer edges j of the floor boards-are supported on the bottom flange ofthe plate 42,1 arid, as will be apparent,

the oor boards close the gap otherwise existing between the plate 421 and the side sill.

-Referring next to the construction shown in Figures 9, 10 and 11, wherein is illustrated the Vmanner of carrying cut the improvements with respect to a single wood sheathed box car. As indicated in Figure 9, the standard steel underframe single sheathed wood box car is usually provided with channel side sills I IIi; specially formed'angle side plates 50, outside pressed side posts 5|; flooring .52; and heavy wood sheathing 53. As customary, the upper ends of the posts 5| are flattened out and riveted to the side plate,

as indicated at 54, and the lower ends are similarly flattened out and 'riveted' to the side sill, as indicated at 55. The posts 5| are usually of U or bathtub section. having a maximum depth throughout their intermediate portions and tapering inwardly and upwardly and inwardly and downwardly at the tops and bottoms respectively, as'shown. Said standard single sheathed cars are generaly constructed with an inside width of 8', 6", and with .8', 9" over the side sills. The

4side sill spacing is somewhat greater than that wherein are employed Z-bar posts 5l2 located outwardly of the plane of the side sills and rigidly secured to the latter by attaching brackets or castings 5|5, similar in all substantialrespects to that type of attaching bracket illustrated in Figure 11 although, as will be understood, the attaching brackets may be modified tonconformy with those shown in any of the other gures previously described. The posts 5|2 are so located that, when the inner Wood lining 540 is applied. thereto, an inside width of 8', 91/8" will be obtained as indicated in Figure 10, thus materiallyincreasing the inside width over the original 8', 6", to conform to present recommended practice. New Z-bar side plates 513 will preferably be employed and, further, the same will be located somewhat higher than that of the original side plates Ellas indicated in Figure 10 so as toobtain an increase in the inside height of the oar. Connection between each side plate and the respective side posts 5I2 is obtained in the same manner as heretofore described, that is, by angle clips or plates 5|4.` The metal sheathing 52| is riveted to the outer flanges of the posts and to the depending flange of the side plate in the same man- -ner as rst described.

The bottom member or plate 521 of the side wall structure is preferably -in the form of anv angle, as shown, and with its upstanding flange riveted to the lower edge of the sheathing and `its horizontal iiange supported on and riveted to the bracket castings 5I5. In the constructionl shown, the posts 5|2 have their outer flanges inwardly offset, as indicated at 5|2a, to accommodate the upstanding flange of the connecting plate 521 and to which it is riveted although, as will be understood, the posts may be coped in a manner similar to that illustrated in Fig- `ures 2, 6 and 8. The two upstanding flanges 515 of the attaching casting are riveted to the web of the respective post, as by the rivets 5I1 which,-

as apparent from Figure 11, are thereby placed in double shear. The horizontal flangesof the bracket casting are riveted to the angle plate 521 as by the rivets 542. In the construction described, no direct connection is effected between the bottom plate 521 and the side sill but in CGI order-to provide means for attaching the ooring 536,Y a separate longitudinally extending plate 54| is employed, riveted to the side sill and connectedl by bolts to the flooring in the same manner` as previously described for the Figure 8 construction.

From the construction just described, it is evident that the single sheathed type of cars may not only be converted to an all steel car but the inside width and the inside height, when desired,

may be increased without in any way disturbing shipped as a complete side. unit of the car for' attachment to the originaliunderframe and car ends. It will also be noted that, in all car constructions, only a minimum number of new rivet holes is required to be made in the original side' sills for the attachment of the post brackets only, there being no direct connection between any of the bottom plates and the webs of thel side sills. l
