Figure 9 is an enlar ed vertical section view taken len hwise 0 one of the l wedge pockets, hereina i ures 10 and 11 are elevational and vertical sectional views, respectively, of the locking mechanism for the auxiliary door. Figure '9 12 is a view similar to Figure 3, illustrating Other objects of the invention will more igure 45 6 is an enlarged horizontal sectional view r referred to. Figanother embodiment of my improvements. Figure 13 is an outside elevational view of the front lower corner of the door illustratedin Figure 12. And Figure 14 is a vertical sectional view-corresponding to the sect ion line 1414 of Figure 13. Referrm ,first to the construction illustrated in igures 1 to 11 inclusive, 20 indicates the usual side plate of a box car, 21 the side facia board, 22 the door lintel, 23 the floor boards, 24 the threshold plate, 25 a car side sill, 26 a supporting block for extended floor boards and 27 one of the door posts or jams, the one at the rear edge of the auxiliary door, it being understood that there will be a similar post at the opposite side of the large door opening.

In the arrangement shown, two sliding outside doors are employed, one which may be termed the main door and designated iary door, which is indicated by the reference character B. In the form shown in Figures 1 to 11, the doors are of the top hung type,

each preferably being provided with a pair of roller carrying brackets 28 -28, each bracket having a roller'29 which rides upon a Z-bar track 30, the brackets being so formed that they clear the outermost flange of the track and the door having its upper edge extending inside of the outermost trackflange, so as to thereby prevent the door from moving outwardl' with respect to the track. The main door is composed of sheet metal throughout, the same preferably being formed with vertical and horizontal corrugations and multiple-ply edges, as described in in Patent No. 1,315,537. The secondary door is also formed of sheet metal of a construction similar, ingreater-part, to the main door A, but a p the side wall of the car and having a double beveled or cam surface 35. The rear lower corner of the door B preferably has secured thereto a double-wedge casting of the form best indicated in Fi re 7 and referenced 36 'so that the same wi l wedge against the respective guide brackets carried by the car body. At the front lower cornersjl'of'each of the doors A and B, that is, the two meeting corners as illustrated in Figure 1, each door is preferably rovided with a 'single wedge bracket 37 of t he type indicated in Figure 8. When the two doors A and B are closed, as

shown in Figure 1, the respective brackets 37 of sheet metal panels suitably united along sheet of the door, the latter being then corru their meeting edges and forming the mam gated so as to provide a rear'vertical ed e corrugation 38, a lower horizontally exten ing corrugation 39, a partial vertical corrugation 40 at'the front edge of the door, and a series of horizontally extending corrugations 41 within the three-edge corrugations referred to the corrugations 41 merging at their ends with the vertical corru ations 38 and 40. At

the bottom of the door a plate 42 is riveted or otherwise rigidly secured to the main sheet,

said plate 42 bridging the corrugation 39 as shown in Figure 3 and providing a'doubleply lower edge. imilarly anotherstri 43 is employed at the rear edge of the door on the inner side of the main sheet, the strip 43 bridging the verticalcorrugation 38- and rive eted to themain sheet on opposite sides of the .8 said corrugation 38, said strip 43'being pref- .3

erably extended at its rear edge and bent to hook-shape as indicated at 44, 'so as to engage over the projecting ed e 45 of 'a wear plate 46 applied to the exposed faces of the post 27.

this manner, a spark and weather seal is obtained for the rear edge of the door B. At the front edge of-the door B, a special construction 'of great strength is employed. The same comprises the extended flange 40 of the partial corrugation 40, made b the main sheet ofthe door, aisecond strip 4 and v a section 48 of angle bar, as best 'shown in m Figure 2. The angle bar 48 has an outer relatively narrow flange 49 extending parallel to the side wall of the car and to which is riveted or otherwise rigidly secured, the extension 40?. The angle section 48 has an elongated leg 50 extended transversel of the caran'dto which one ed eof the str1p 47 is riveted or otherwise rigi y secured, as mdicated at 51, it bein observedithat the other edge of the strip'4 is secured to the'main sheet of the door at a point inwardly of the corrugation 40, as indicated at 52 and that the strip 47 is extended angularly inwardly from the main plane' of the door. As best shown in Figures 3 and 4, the flange 49 of the- .aalgle section 48 extends for the full height of the door B, but the leg 50 terminates a short distance below the lintel and a short distance above the threshold. The lower horizontal wedge pocket castin strip 42 and the upper corresponding strip 142, which bridges the top. horizontal edge corrugation 139, are extended, as indicated at 53 in FigureQ, and-thence bent at-right angles, as indicated at 54 and angle section 48.

t0 the 2 'ZVVith the construction described, it be sist bending from thrusts imparted parallel to the side wall of the ear-and race the member '48 a ainst rotation aboutits longitudinal axis, an also to resist bending or exerted inwardly against the door It'w'ill be noted also that the double-ply edge overhangs the front edge of the main door A and is therebyadapted to provide a weather or spark sealatlthe meetingfedges of the two doors. I elongated le 50 of the angle section The 48' provides a suite. le support for a heavy wood nailing block 55, which may be bolted to'the angle section, the inner faceofthe n'ailing-block '55 bein in line with the inner face of the post 27 re the auxiliary door B is not required and-when it maybe left for a considerable time in its closed position, the door'Bmaybe "locked in such closed position and boards nailed to the post 27 and the nailing block 55 to continue the inner-sheathing 56'of thecar. f To revent ,thefront ed le oi theilo'orf rom in spr outwa emp oy t e following fixtu l efi. Partial? countersunk within the lintel and partia y countersunk withinthe threshold and anchored by bolts 57 -.'-57 are wedged pocket castings designated generally by the reference character C. Each C, as best shown in Figures 3', 4, 5 and 9, as a vertically extending loop-shaped flange 58 with a-tapered en.- trance, each loop being opened toward the post 27. 'Cooperable with the. loop-wedging with brackets 60-60 secured to the top and flanges 58' are heavy lugs 59 formed integral bottom, respectively, ofthe angle section 48. With this construction, the front edge of the door B is properlyrg-uided as the door is moved to its closed position and, wzhenthe lugs 59 are properly wedged Within thefiamges 58, outward movement or springing .cfthe front edge of the door B is 1prevented.

To lock the door B hits 0- osed position, I employ the following means, as best illustrated in Figures 2, lOand 11. Extending horizontally through the post 27 is a long arm .61 of 'a U-shaped bolt, the short arm 62 thereof being extended back partially into the post 27 and leaving the loop proper 63 of the bolt spaced away from the face of the post. On the lower or elongated arm 61 of the U-bolt, is pivoted a lock lever 64 having an offset handle (Sh/and 'an arcuate projection 66 of T cross; stion. The projection 66 is adapted to swing within a corresponds ingly T-slotted casting 67, mounted within one of the horizontal corrugations 41 of the door B so as to lie totally outside of the inner main plane of the door, as best illustrated in Figure 11. When the lever 64 is in-the posi-- tion shown in Figure 11, it is evident that the door B will be prevented from movement in an opening direction and also, when the lever 64: is moved from engagement with the cooperating member 67 of the door, the latter may be moved to its open position without any interference. To hold thelever 64 in its locked position, the lever is provided with a short arm above its pivotal point, to which is pivotally connected a hook latch 69 adapted to take over the short arm 62 of the U-bolt, as shown best in Figure 11. The lever 64 is released by disengaging the latch 69 from the U-bolt as will be understood by those skilled in the art.

Referring next to the construction illustrated in Figures 12, 13 and'14. The structural features of the doors are substantially the same as those illustrated in the figures previously described, except for the s ecific differences hereinafter described. 11 the arran'gement shown in Fi ures 12 to 14, the door is of thevso-called ottom hung type with the supporting rollers 129 ridin upon a channel shaped track 130 supporte from suitable brackets secured to the side sill. The top edge of the door is guided beneath a longitudinally extending, approximately Z-sec- 'tioned stri 70, secured to'the outer de end- .ing flange 71 of. a Z-bar 72. Along the ower edge of the door, is provided a Z-bar 73 having depending flange 7 4 engaging'behind the channel track 130 so as to revent the bottom edge 'of the door from ing sprung outwardly. v To adequately support;each of therollers 129 on a sheet metal door of the preferred type, I employ the following arrangement.

t each corner where a roller is rovided, a

portion 75 of the mainv sheet 0 the door, which would ordinarily form a continuation of the lower horizontal edge corru 'ation 76 is extended vertically in line with most plane of the door and spaced from the re-inforcing strip 77, which is secured to the bottom edge of the door, as best shown-in Figure 1-1. To brace the vertical portion 75 of the sheet metal, I secure beneath. it, an extra strip 78 having flanges 9 at each end-secared to the strip 77 andja vertical longitudi 'na'lly extending -'seetion .80, immediately beneath the plate portion 75. The extra plate 78 and p0rtion"7 jam in turn braced or reinthe outer-- :i a M t 1 1M1 9 ends is supported by the three plates 81, 75 and 80 at one of its ends and "by the strip 77 and Z-bar 73 at its other end, said journal 70 82 having the roller 129 rotatably mounted thereon. With this arrangement, I provide the necessary strength against crushing or collapse of the parts from vertical loads or thrusts and also againstlateral thrusts while maintaining the weight at a minimum.

I have herein shown and described what I now consider the preferred manner of carrying indentations, said door including portions diverging outwardly, and a member having a portion arranged substantially normal to the main plane of said door and connecting with the spaced end portions of said diverging portions to provide one edge thereof of approximately triangular tubular cross-section.
