The present invention has been illustrated Y in connection with a car having a main door and a supplementary door in the side wall thereof. When a door openin ofordinary width .is required the main oor only is opened', the .supplementary door remaining in fixed position. Thesupplementary door may be provided with a movable door jamb, said door jamb being fixed to or detached from saidsupplementarydoor, as preferred.A VVhen'a doorway of extraordinary width is required the main door, the supplementary door and said door jamb are moved doorway.

Referring first to Figures land 2, the car wall is indicated by the numeral 1, the side plate is indicated by the numeral 2, and the side sill 'isindicated b the numeral 3. The door jambs 1-4' de 'ne a wide doorway,

intermediate of the width of which is thel movable door jamb 5, which may be moved longitudinally of the car when it is desired to provide an unobstructed doorway of rel .atively great width. Movable door jambe door. These doors may be top hung or bottom hung, the manner .of hanging being independent of the p resent invention. According to the illustrated embodimentof the 0 present' invention,- thev supplementary door 7 is secured to the movable jamb 5. Said movable jamb in the illustrated embodiment compr1ses an angle 8 of structural steel, the

reentrant angle of which may receive a tim-V ber 9, constituting a nailing strip to which boards may be conveniently nailed when it is .desired-to use the car for the carryingv of grain or other lading in relatively small particles. From an inspection of Figure 2 it will bev noted that the movable jamb 5 is provided with a Z-bar 10 forming a pocket for receiving the edgeo'fthe main door 6. Arranged adjacent to the right-hand jamb 4 is a Z-bar 11 provided with an angle 12 having a flange for receiving a hooked over edge portion of the main door 6. The main door 6 fm'ay be provided with the hingedv member 14 for engagement with the hasp 14 carried by the movable jamb 5. The slidable retaining member 14 is adapted to securely hold the hinged portion 14 in locking relationship with the hasp 14.

Steel doors have been provided in the past, but in `vso far asv applicants are aware saidl doors' have not been entirely satisfactory. Steel doors have been provided made of members which may be fabricated only under rather special conditions, so that repairs have be'en very costly. According to the ypresent invention, each door is provided at itsv margins with rolled structural steel shapes whlch are purchasable in the open market. Said marginal members are -very sturdy and are positioned to take the worst of the shocks encountered in service. Conout of clos-ing relationship with thel nected to said marginal members are a-plurality of steel members, all of which may be swedged and machined when cold, so that l `right-hand margin of the door 6 as said door is viewed in Figure 4 is defined by the W-bar 18. It will be noted that one leg, indicated by the numeral'19, of the W-bar 18 is swedged inwardly forthe purposeof providing'a hook which is adapted to -fit over the angle 12 carried by the stationary door j amb 4. The

structural steel. members 15', 16, 17 and 18 are riveted together to provide a rectangular frame, said members having-certain of their flanges crimped slightly at the corners of said frame to permit said structural steel members to present plane surfaces on both sides of said frame. v

Referring to Figure 8, it will be noted that the structural steel member 16 has lriveted theretothe swedged steel member 20. A

Having in mind that the right-hand sideof each of Figures 7 and 8 indicates the outside of the car, while the' left-hand side of each of saidl figures indicates the insideof the car, it will be noted that the swedged steel member 20 is positioned relative to the` structural steel member 16 so as to shed rain and other forms of precipitation. Said swedged steel member 2O is bent inwardly toward theA rear of the door, that is-toward the interior of the car, and provides a flange 21, which flange 21 extends substantial parallel with the planes provided by ther inner and outer sides of the frame provided by the structural steel members 1-5, 16, 17

`and 18. Said flange 21 is secured to the panel 22, which panel is positioned on the inner side of the flange 21. The swedged steel member 2O is located midway of the width of the door, but stops short of the corners of said door. Gussets 23-23 are provided at the two corners, which have overlapping relationshipv with`the swedged steel member 20. Said gussets 23-23 areA also swedged to provide flanges 24-24 located in substantially the same plane-as the flangel l21, overlapping flanges ,being 'crimped to y Apermit the positioning of flanges 21 and 24-24 in substantially the same plane. Said gussets are also riveted to theinner side of the frame provided by the structural steel members 15, 16, 17 and18.l

Located below the panel 22 is the channel member 25. .Said channelA 25 has the upper mamie flange 26 secured to the-inner side of thel as indicated by the numeral 28, which flange 28 is riveted to the outerl surface of the panel 27. Located at the lower edge of the panel 27 is the .channel 29, which has the upper flange 30 secured to the inner surface of panel 27, being located between said panel 27 and the panel 31. The lower flange 32 of the channel 29 is secured to the outer ysurface of the panel 31. The lower edge of the panel 31 has Secured theretothe swedged steel member 33, which swedged steel member 33 has the flange 34 located'on theinner surface of the panel 31. Said swedged steel member 33 is riveted to the structural steel member 17.

Arranged at the two sides of the door 6 are the two gusset plates 35-35, which have overlapping relationship with the gussets 2323 and the channel member 25. f Said ygussetsb35--35 conform in'cross section at their extremities tovsaid gussets23-23 and channel member 25 and are'riveted to same as well as being riveted to the panels 22 and 27l and to the rolled structural `steel members Positioned at the two ends ol the panels 27 and 31 are the gusset plates 36-36, `having extremities conforming to the corresponding portions of the gussetplates 35--35 and to thekchannel 29. Said gussets 36--36 are 4riveted to the panels 27 and 31, the channel 29 the side structural steel members 15 and 18 and to lower corresponding gusset plates y 23-23, which are identical in shape withv the upper gusset plates 23-23 referred lto above.l Said lower corner gusset plates 23- 23 are riveted to theswedved steel member 33, said lower cornergussett" plates an'd lsaid member 33 beingriveted to the remainder of lthe door to providey a solid job. -It will l .be noted that the lower structural steel member 17 is cut away to provide space for rollers `37-37, which may be rotatably mounted in any preferred way. The pockets in rear of the gusset- s 23, 35 and'36 along the side margins of the door are closed by the plates 3838. rIhe pockets in rear of the steel members 2O4 and 33 and j their adjoining'gussets23 are closed by other plates 38-38. Said members 38-38 may be crimped attheir overlappedgend portions, whereby` the greater extent ofsaid members 38 along the four margins of the door may lie in engagement with the structural steel shapes 15, 16, 17 and 18.

The description of door 6 which appears above will be sufficient for an understanding of the construction of door 7. The invention is not limitedto constructions having a pair of doors on each side of the car, but is :equally applicable to single doors.

ra .rectangular frame made up of It will be noted that the-inside of each of the doors issubstantially flat, fthe overlap between adjoining panels and wtheir,`

strengthening members necessitating onlya slight divergence vfrom a perfectlyl flat conu dition. The outside of the door with its reinforcing channelsl ,presents4 a workmanlike appearance, and great strength is had'pe i unit 'of Weight byreason of the box girders provided by the members20 andf 33, the

channels -25 and 29 and the Vgussets 23,254

and 36, together withfthe backing members jacent to theltwo side margins offthe door are identical 1in shape and therefore interchangeable. Thematte'r of manufacture and repair is therefore greatly simplified.

It will) be noted that starting from'the top of each?Y of the doors theparts -are soy 'overlapped that the members closest to the top ofthe car are lapped on the outside of the member next adjoining at a lower level.
