CAR noon Application inea Aprn as,

This invention relates to improvements in car. doors.

As is well known to those skilled inthe art, there are many railroad officials who ,pref fer box car doors of the iiush type on Ythe grounds that the same provide for better protection against the weather and also better' protection against theft or unauthorizedV access to the interior of the car. It is alsowell known to those skilled inthe art that there is a general tendency to provide rrelatively large, wide door openings in box cars in order to increase the usefulness of the car-z for carrying different types of freight, particularly automobiles, which necessitate door openings of much greater width than the usual door opening of a box car.- Coupled with the demand for wider door openings, which involvethe use of auxiliary and main doors, and the desire on the part of many railroad oilicials for doors of the flush type, is the increasing demand fordoors of the socalled sheet metal type which provide greater strength and cost appreciably less to maintain. f

One object of my invention, therefore, is

.to provide a door arrangement particularly adapted for box cars, which will efficiently and economically meet all of the requisites hereinbefore indicated and, more specifically to providera double, all metal, flush door arrangement. l Another object of my invention is to provide an improved sheet metal type of door particularly adapted `for Hush mounting wherein tained.

Another object Vof my invention is to provide a door arrangement particularly adapted forboX cars wherein is employed an auX- ihary door forobtaimng greater width of door opening-when required, in combination with a `flush main door, with provisions for obtaining satisfactory sealingy against weather and theft.

Other and more specific objects of my invention will more clearly appear from the claims hereinafter followln the drawingsrforming a part of 'this great strength and rigidity are obl 192s. serial No. 272,038.

specification, Fig. l is a side elevationalview of a portion of a box car showing myimy' provements in connection therewith. Fig." 2 isavertical, sectional view, parts` being brokenaway, corresponding to the section line 2-2 of Fig. V1, the scale of Fig. ,2 being appreciably greater thanthat of Fig. 1. Fig. 3 is a horizontal sectional view correspond:V- ingto `the line 3-.3 of Fig. l, the scale being larger than that of Fig. 1 and parts being broken away in order to accommodate the ligure on the sheet. Figs. l and 5 are detail,

vertical sectional views corresponding to the section lines 4-4 and 55 of Fig. 3. VAfind Figs. 6, 7 and 8 vare viewssimilar to Fig. 3 showing three modified forms ofthe forward edge of the auxiliary door. A 1 Y lin said drawings Yand referring first to the construction illustrated in Figs. 1 to 5, inclusive, the side wall of the car isind-icated at 10 land the wide door opening thereof is defined by a threshold 11, lintel 12, and posts 13 and 14. Referring to Fig. 2, the threshold is'shown protected by a sheet metal plate 15 and the threshold vis recessed er rabbeted as indicated at 16 to permit of the flush positioning of the doors. Similarly, the posts'13 and 14 are protected by plate covers l? and L18 and are also cut back or rabbeted as indicated generally by the reference character Al and the main door by thereference character B. The detail construction of these doors will be described hereinafter. Each is mounted for flush positioning when over the door opening and to this end, lower track- 23 is employed, with which the door A is associated, and a corresponding upper track 24. These` tracks, both of whichare shown as `are employed, the auxiliary door being`indicomprised of Z-bars, have a straight section parallel withthe side wallof the car,` as best indicated in Fig. 3 and then an inwardly inclined portion, onlyone Vof which is indicated at 123, for the lower track. Cooperable i with the lower track are two hanger brackets along the rear edge of the door A and, at its upper end, is pivotally associated with a roller hanger bracket 29, the roller 39 of which rides upon the upper track'2-l. A second roller hanger bracket 3l is liziedly se.-

cnred to the upper righthand corner of theV door A, as best shown inllig. l. f -Asindicated in Fig. 2, the hanger brackets'are all so formed as to have a channel formation enibracing the depending flangesof the bottoni 'and top tracksrespectively.y The door Bis correspondinglymounted on similar lower andupper tracks 2n3randi22-/ll and is provided with an upper fixed roller bracket 231i,

affixed lower hanger bracket 225an operating shaft 22'?, the latter having a hanger bracket 226 pivotally secured to its lower end, and a correspondingrolle'r bracket 229 pivotally connected thereto at its upper end.

The means specifically` shown and above described for supporting the doors 'and adapting the latter for flush positioning, may be varied without departure from myinvention, the particular nieans shown being of lwell known form and b ing somewhat similar to those disclosedin my. prior Patent 1,395,- 080, of @ctober 25, i921. As either door A or-B approaches its closed position, the forwardredge thereof will be moved inwardly to the flush position, due to the inclination of the tracks'and, after the door has been adif'anced in a closing direction to the full e5;- tent, the voperating shaft 2i' or 2227, as the case may be, is then actuated and the corresponding 4rear edge of the door forced-in-A wardly to the flush position.

Referring to the'inain door B, the saine is comprised *principally*A of sheet metal and may be constituted of a single sheet or preferably made in three panels arranged horizontally one above the other. The inetalsheets are provided with outwardly erteiidedvertical edge vcorrugations 32 and 33 and between therlatter and merging at 'their ends therewithA are a plurality of horizontally extending and outwardly disposed corrugations 3fl.

uThe vertical corrugations32 and are so positioned with respect to the front and rear edges of the door proper as to leave flat marqv np L' I i. f..

gins @o and eo respectively, the latter being somewhat 'wider than theformer, in order to accommodate the bearing bracketsA for the operating shaft.

vAs shown'best in Fig.l3', the verticall corrugations are braced 'bymeans of bridging strips37 and 33, the former preferably having its outer end bent back :so as to envelop the'corresponding marginal portion 35, the

'tivev corrugations. lhas'flat marginal portions on all four edges terasse bridging strips being riveted or spot welded to the main sheets of the door on opposite respectively, over which ar-e applied the corresponding bridging strips 334 and 43a, respectively, as shown in Fig. 2, said bridging strips being also'rivetedor spot welded" to the main sheets above and below their respecln this manner, the door and each,v marginal portion -consists of two or more plies of sheet metal, thus providing a door of: relatively great strength per unit of weight and one well adapted to resist'stresses occurring. in. any direction. Further, it will be. noted that the edges ofthe door, although consistingof two or more plies of metal, are of comparatively small over-all thickness, thus requiring. only 'relatively shallow recessing or rabbeting of the meinbersdeining the door opening. y Y

The auxiliary-door A Vis constructed the saine as the door B throughout the niain body portion tlier-eofand alongtlie top, bottom and rear edges. A different construction is necessarily employed at the forward edge of the auxiliaryvdoor A, the details thereof being! shown in Fig. 3. At its forward edge, the door. A, instead of having a vertical corrugation with a flatinarginal portion therebeyond, has the sheet inclined outwardly, as indicated at 39, to a plane preferably corresponding to theplane definedl by the outermost portions of the strengthening corrugat'ions or .indentations The sheet metal is then extendedV as'indicated at 40 in a plane parallel with the main plane of the sheet. SelCured to this forward edge portion of th-e auxiliary door and on the inner side thereof is a preferably rolled metal post lll. The latter is of generally channel cross section-and has a long flange l2 on the side adj acentthe doorl and a second flange43 on the side remote from and the-bottoni section at 45. The latter'is riveted, spot welded or otherwise rigidly secured to the flat marginal portion 40 of the door and the flange 4l is similarly rigidly securedtothe sheets Vcomprising the door A -in thefinain plane of the latter and at point-s inwardly of the inclined section 39. As jwill -be clear from an inspection of Fig. 3, an inwardly facing channel lor recess is thus pro- 4vided at the forward edge ofthe door A for the reception of the wood post or nailing post 46, which is suitablysecured within the metal `post ,4l by any' suitable means* such as bolts and thus adapting the wood posts for renewal. --The sheetmetal sections 39 and 40 and the sections Ll2 and lll of the post, together" iX Loca 'ciA constitute a tubular arrangement which ini- -parts great strength and rigidity to-the forward edge. of the auxiliary door'and one well adapted to resist either twisting or distortion from bendingin any direction. f i

The outermost iange43 isso extended as to overlap to an appreciable distance, the inner face of the forward edge of the main door B `and together with an angular strip 47 whichisriveted or otherwise securedtoxthe post 41, constitutes aguide and recess for the multiple-ply forward edge of the door B and also constitutes a weatherv seal therefor. In `this connection', it will be noted thatthe g vertical edge corrugation 32 of the door B forms a bafll-e for rain orthe like when the car is traveling toward the right, i as viewed Vin Fig. 3 and, similarly, when the car is traveling to the left, the forward edge portion of the auxiliary door A, and more particularly theinclined portion 39, and metalp'ost 41, provide a similar baille, thus minimizing the amount Vof rain, snowor dirt that may be driven into the sealing joint between the twodoors. Y

In addition tohavingth-e forward edge of the auxiliary door A moved inwardly through the tracks and hangers, it is important that said forward edge be rigidly held .against lateral movement when the oor occupies a closed position. For this'k purpose, I secure to the threshold, a plate 48 which is provided on the upper face thereof with a groove `49 having a relatively wide entrance vopening or '5 mouth 50, the groove then beingV inclined away from the side wall of the car for a` considerable distance and having a iinalportion 51 which is parallel to the side wall'of the car. Cooperable with the-cam plate'48" is a ucasting 52 applied to the bottom yofthe wood post 46, said plate52 having a rounded down` Vwardly projecting stud 53 adapted to enter the groove 49, as best shown in Figs. 3 and 4. Although I have ldescribed the details Vas f,- applied to the lower end of the .wood post 46,

only, :it will. be'understood` that a duplicateV arrangement is employed at the top thereof. Vith the arrangement described, as the forward 'edge ofthe doorA approaches final position, the upper and lower studs 53 enter their respective cam slots 49 and the forward edge of the `door is camed inwardly and then locked against lateralmov-ement when the studs enter the straight portions 51 of the slots.V Itwill also be understood that the slots 49 serve to positively limit the movement of the door A in aclosingdirection and further, when the rear edge of the door A is thrown inwardly to Hush position, as shown LinFig. 3, the door is positivelylocked against movement horizontally until the rear edgeis i again i thrown out by the i operating shaft. 1

Referring to the-modification illustrated inrFig. 6, the main. door isy of the same construction asthat previously described; The

auxiliary door has the sheet metal thereof outi wardly inclined at its'forward edge, as indicated at 139 and thenceextendsparallel to the side wall, as indicated at 140. kA, somewhatisimilar channel shaped vmetal post 141 flat marginalportion 140 of the door'proper.

-Inthisinstanca however, the iange 142 of the postis not extended over the inner face of the mainlportions of the sheet-s but is Vleft in line therewith and an additional plate is einployed, the saine being riveted or spot welded is employed, riveted or spot welded to the g to the flat main portions'of the sheets and'also to the flange 142 of the channel post. The weathersealing strip 147 cooperates with the other extended flange 143 of the post, to prowith the modification of F ig. 3.

Referring next to the modication `shown in Fig. 7, the main door B remains the `saine and the auxiliary door has a similar outwardly sloping'sectioii 239v terminating in a flat marginal portion y240. In this construction, the post member is preferably comprised of two Z-sect-ion elements 2 41 and 341, the saine having theirflanges 245 landj345 overlapped and secured togetherfand'also securedito the flat marginal portion 240. The member 241 hasone of its flanges elongated, as `indicated at 242, the same being riveted or spot welded to the main flat portions ofthe door sheets.

Infthe modification' shown Vin Fig.'l 3, the auxiliary door preferably hasV the same Out'- -wardly'sloping section 339 flat marginal portion 340, to which is'rigidly "secured a special section 70, they samehaving an elongated flange 71 overlying and rigidly secured to the main flat portions of the sheets; a transversey Y ly extending web 7 2.- and a` Vnarrower outer v flange 7 3, the latter being riveted or Votherwise rigidly secured to the flat marginal portion 340. Said flange 73 is preferably flared out- Y wardly, as indicated at 74, to form-a guidel for 77 thereof, being secured to the member 70' at the corner thereof. A third'flange 7 8 of the member extends transversely inwardly and provides a backing for the wood post 346. The yfourthV flange 79 of said member 7 5 exy tends parallel ,withl the side wall ofthe car and,in conjunction with said flange 7 3 forms va pocket or recess for the reception Vof the forward end of the main doorB and also a weather 'seal at `the-meeting edges of the two doors.

I have herein shown and described what I now consider the preferred manner of carryc. est) ing out my invention, but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto. i
