(Cl. Ilm-404) This invention relates to improvements in house car construction. Many thousands of house cars rendered unsuit able for use by present day requirements are owned by the railroads. 5 Of these cars a large number have side wall constructions in which the sheathing, posts and braces and side sills are of wood. The underframes of these cars are, how ever, of metallic construction and where these 10 underframes are still serviceable it is evident economy to again place them in service if possible. To this end there has been submitted to the rail roads a scheme of conversion by means of which modern metallic house cars are obtained. re employing the existing satisfactory underframes of the old wooden box cars. ' The scheme of conversion contemplates neces sarily the attainment of modern house cars ca pable of carrying heavy loads. y The accomplish 20 ment of this purpose presents a diñicult problem in many instances and particularly so in the class of wooden cars wherein the underframe embodies center and intermediate metallic sills and in which the conversion to metallic house cars 25 would leave the underframe without side sills. Moreover, since the car side walls of the con verted metallic walls function as girders they would impress stresses upon side sills which the old side sills could not satisfactorily carry. These 30 considerations, together with the further factor that conversion must be met with as little varia tion as possible in the existing members whichl are to be reused, render the problem confronting applicant particularly acute. . It is, therefore, the object of this invention to 35 overcome the obstacles above noted and to pro vide for the conversion of cars of the character described to metallic‘cars having the requisite capacity and strength demanded of modern rail 40 way house cars. ' With this object in View and others which will become clear as the description of the invention proceeds, this invention embodies the novel struc ture and combination of parts hereinafter de 45 scribed and particularly pointed out and de iined in the appended claims. In the drawings forming part of this speclñca tion: ' Figure 1 is a partial elevation of a railway 50 house car embodying the invention. ~ Figure 2 is a horizontal section taken on line 2-2 of Figure 1, omitting a showing of the inter , mediate posts and sheathing on one side of the 55 car. The floor boards are omitted from this view in order to better show the car underframe con struction. - Figure 3 is a vertical section taken on line 3-3 of Figure 1. Figure 4 is a vertical section taken on line 4-4 5 of Figure 1. . Figure 5 is a vertical section taken on line 5-5 of Figure 1. Referring to the drawings in which a pre ferred embodiment 'of the invention is illustrated, 10 a railway house car designated bythe numeral III is partially illustrated. A portion of the car side wall construction extending from an end of the car and partly into the door opening II is indi cated at I2. It will be understood that the re 15 maining portion of the car side wall I2 is comple mentary to that portion and that the car side wall on the other side of the car is similar in construction. Each side wall, which is preferably constructed as a. unit for application to the underframe of the car hereinafter referred to, comprises door posts, one of which is indicated at I3 and spaced intermediate side posts I4. The door posts I3 will, of course, define the vertical boundaries of the door opening II in each side of the car. The door and intermediate posts are secured at their upper portions to the depending leg I5 of a side plate I6 which extends continuously from end to end of the car. The side plate I6,'which is 30 Z-shaped in section, is disposed with its web I1 arranged horizontally and its inner leg I8 extend ing upwardly and providing a means for attach ment oi the ends of the car roof, designated gen erally by the numeral I9. A reinforcing chan- 35 nel member 20 is secured to the upwardly ex tending leg I8 of the side plate by means of rivets 2I passing through the web 22 of the reinforcing member. The intermediate posts and the door posts are secured to the reinforcing channel mem- 40 ber, this securement in the instance of the inter mediate posts I4 being effected by means of rivets 23 passing through the ñange 24 of said posts and the web 22 of the reinforcing channel member as well as through a filler plate 25 disposed be- 45 tween said post flange and said web of the channel member. At their lower portions the door posts are secured to a channel shaped mem ber 26 by means of angle clips fastened to Ian inwardly extending iiange 21 of said post as by 50 means of rivets 28 and to the web of the chan nel member 26 by means of rivets 29. Each of the intermediate posts is secured to the channel member 26 by means of a bracket member 30 disposed below the lower end of the post and pro- 55 2 11,108,809 vided with flanges 3| arranged on opposite sides of the web 32 of said post and secured thereto as by means of rivets 33. The bracket 30 is also secured to the web of the channel member 26 as by means of rivets 34. Metallic sheathing is incorporated in the side wall constructions and extends from each door post to the'corresponding end of the car. This sheathing preferably embodies a plurality of metallic sheets 35 which extend between the posts and have their adjacent margins overlapped upon and secured to the intermediate posts |4, as indi cated at 36. At their upper margins the sheets 35 are secured to the depending leg |5 of the side 15 plate I6 while at their lower margins said sheets are secured to the channel members 26 by means of angular metallic connecting members 31. Each member 31 is preferably Z-shaped in section to provide an outer upstanding flange 36 riveted 20 along the lower margins of the metallic sheets, as indicated at 39. The web 40 of the Z-shaped con necting members extends inwardly from said up per flange and from this web there depends a vertical flange 4| by means of which the connect ing member is secured to the channel member 26, the rivets 34 being utilized to this end. It will be apparent that the web 40 of the connecting mem ber will be coped in order to permit the projec tion of the flanges 3| of the attaching brackets 30 30 through said webs for the securement of said flanges to the lower portions of the intermediate posts. The construction above described which, as re ferred to, may be constructed as a unit,_ may then 35 be applied to the underframe end of a car which is to be converted, or of a new car. This applica tion is effected by the securement of the channel member 26 to the ends of the cross members of said underframe hereinafter described so that 40 the channel members are then impressed with the function of side sills in the completed car con struction. It will be apparent that in such con struction the side plates, side sills and posts con stitute girders on each side ofthe car capable of 45 carrying stresses imposed upon the underframe of the car. Under these stresses the posts func tion as tension members, the side plate as a com pression member and the side sill as a tension member. 50 , The underframe to which the side wall con struction is applied embodies a center sill 42 and spaced intermediate sills 43. The center sill com prises, briefly, spaced vertical plate members, one of which is indicated at 44, an outer angle mem 55 ber 45 secured to the upper margin of each of intermediate sills and the crossbearers is not necessary and will not be given inasmuch as the structure of these parts is well known. In addition to the foregoing parts of the under frame the latter comprises bolsters, one of which is designated at 55 and end sills, one of which is indicated at 56. These parts are of a well-known type and need not here be described in greater detail. ' As hereinabove stated in the application of the car side wall to the underframe, above referred> to, the channel member 26 is secured to the ends io of the cross bearers and bolsters. This secure ment is effected in the case of the crossbearers by means of rivets 51 which are driven through 15 the web of the channel member 26 and through openings existing in fianges 56 formed on the crossbearers. Similarly, the channel member 26 is secured to the ends of the holsters 55 as by means of rivets 59 extending through the web of the channel member 26 and through existing openings provided in a flange 66 of each of the crossbearers. It will be apparent from the fore going that in the instance of a converted ho'use car the existing structure is utilized without modi 25 fication. The rivets 59 utilized in the securement of the channel member 26 to the ends of the bolsters 55 are employed to fasten to said bolsters bracket members 6| which constitute the connect ing and attaching brackets between the lower 30 ends of the intermediate side posts disposed op posite the bolsters and the car underframe. Each of the brackets 6| is supported upon a plate con struction designated 62 extending outwardly from the ends of the holsters 55. 35 Within the door opening, the extent of which is defined by the door posts I3 and at the points in alinement with these posts, the ch'annel shaped member 26 is reinforced in such a manner as to carry directly the stresses imposed thereon to the 40 intermediate side sills. It is apparent that within the door opening the channel members 26 act as beams and that they do not have the advantage of the intermediate posts in assisting them in carrying the stresses imposed upon said members. 45 The preferred reinforcement for the channel members 26 in the door opening of the car side Walls takes the form of a strut or compression member 63, preferably channel shaped in cross section, as indicated in Figure 1 of the drawings. 50 The strut 63 is bent at its ends so as to provide an attaching portion 64 at its upper end, by means of which said strut is secured to the lower in turned flange 65 of the channel member. At its lower end the attaching portion of the strut 63 55 is designated by the numeral 64-A and this at taching portion is secured to the lower end of the intermediate sill 5| as by means of rivets 66. the plate members and angle members 46 ar ranged in spaced back to back relationship be tween which is received the lower portion of the plate member 44. The angle members 46 are 'I‘he intermediate sill 5| being a vertical mem 60 secured to this lower portion of said plate mem ber. A flanged diaphragm 41 extends between ber, it is desirable that the 'stresses imposed there 60 and is secured to the plate members 44 as by on be vertical stresses. Inasmuch as the strut 63 is arranged at an angle to the intermediate means of rivets 46. A cover plate 49 is secured to it will be apparent that said strut under load the diaphragm 41 and extends across the angle sill, imposed upon the channel 26 will tend to trans-A 65 member 45 to which it is additionally secured as mit a compressive stress to the intermediate side 85 by rivets 56. sill. To offset this compressive stress and to in Each of the intermediate sills 43 comprises a sure that the intermediate side sill will be sub plate member 5| to the upper margin of which jected to tension rather than compression, a an outwardly disposed angle member 52 is se 70 cured. A similarly disposedangle member 53 is brace 61 is utilized. This brace-is provided with a lower angular portion 66 secured to the lower 70 secured to the lower margin of the plate mem part of the intermediate sill in alinement with ber 5|. Crossbearers, designated as a whole by the brace 63 by means of the rivets 66 securing the reference numeral 54, extend from the center the latter brace to the intermediate sill. An sill outwardly beyond the intermediate sills 43. angular attaching portion 66 is formed at the 75 A more elaborate description of the center and upper end of the brace 61 by means of which 3 2, 108,309 said brace is attached to the center sill 42 by means of the rivets 50. By virtue of the con _struction` just described which, as hereinabove indicated, will be- utilized opposite each of the door posts and intermediate said door posts as required, it will be clear that the channel mem ber 26 which serves as a side sill for the car will be capable of acting as a beam and successfully resisting stresses imposedthereon by means of 10 heavy loads trucked across the sill and into the car. These loads often reach a magnitude of wardly and secured to said intermediate sills below said cross bearers, compression members secured to said intermediate sills below said cross bearers extending inwardly and upwardly and se cured -to the upper portion of said center sill, said compression members >carrying the horizontal component of the stresses imposed thereon to said center sill whereby said intermediate sill is subjected to the vertical component of said stresses and metallic side walls comprising inter I10 mediate and door posts,'side plates and metallic sheathing, said posts being rigidly secured to said side sills and side plates, said sheathing being construction of the car side wall between each secured to said posts, side sills and sideplates. 2.

' v . With particular reference to Figures 2 and 5 compression members secured to the lower por of the drawings it will be observed that a strap 30 member 69 connects the channel member 26 with the intermediate sill opposite each of the inter mediate side posts where said posts are spaced from a cross member. These strap members con stitute tension members. One end of each of the strap members is riveted to the angle member 52 of the adjacent intermediate sill. For the at 35 tachment of the strap member 69 to the channel side sill 26 the following construction is utilized. The bracket member 3l! is provided with a hori zontal ilange 10 which extends through an open ing 1I formed in the web of the channel side sill. 40 'I'his ilange 10 is secured to a strap member 69 as by means of rivets 12. It will be clear from the foregoing construction that any tendency of the tions of said intermediate sills extending inwardly and upwardly and secured to the upper portion of said center sill fortransmitting the horizontal component of said stresses to said center sill, tension members connecting said side sills and intermediate sills, and metallic side Walls com prising intermediate and door posts, side plates and metallic sheathing, said posts being rigidly secured to said side sills and side plates, said 35 sheathing being secured to said posts, side sills and side plates. 3. A metallic railway houser car converted from a house car having originally wooden side Walls and metallic underframe including a center and 40 intermediate sills and cross members, said con verted car comprising said original sills and cross channel side sill 26 to rotate about its upper por- ' members, metallic side sills secured to the ends tion will be resisted by means of the strap mem ber 69 which will be placed under tension and this stress will be carried directly to the adjacent intermediate sill. _ . It is clear from the foregoing description that the invention successfully provides for the con 50 version of an old wooden sheathed car into a modern metal sheathed car, although it is to be understood that the instant invention may be uti lized as readily in new car construction. It will, thus, be-apparent from the foregoing 55 detailed description of the instant invention that the objects thereof areiachieved by the disclosed construction. However, it is not intended that the invention be limited to the details of the structure illustrated and described, it being ap 60 parent that numerous changes and modifications of theœ precise details will be manifest to those skilled in the art.
