2,iO9,515 3 of the rear post plate which forms a stop for the door as previously described. Figure 5 illustrates the application of a grain door 49 to the post structures, the latter being recessed at their innet corners to accommodate the grain door with the inner face of the latter flush vp'-th the inner side wall of the car. In the modiflcation illustrated in Fig-ure 71 door posts 50 and 51 are of Z-section with portions 10 of the flanges nearest the outer face of the car bent inwardly, as at 52, the wooden portions 53 of the posts being recessed at their outer opposing comers to'receive flanges 52. The door comprises flat body panel plates 54 15 having a W-shaped front edging 55 and a zshaped rear edging 56 and transverse reinforcements 57. The inwardly extending lip 58 on the front edging 55 projects inwardly of the inside plane of the door proper so as to abut against 20 the inturned flange 52 of the front post to Iiinit the closing movement of the door and to abut against the inturned flange 52 of the rear post to limit the opening movement of the door. A spark strip 59 on the front door post 5 I co25 operates with the forward portion of edging 55 to form a front seal, and cooperating strips 60 and 61 on the rear post 50 and the rear door edging 56 cooper4te to form a rear seal. The recesses in the outer opposing corners of the posts so permit the forward portion of edging 55 to move beyond the hmits of the door opening X so that the latter i.s in nG ways restricted by the interengaging door and post parts. In Figure 8, the front door post plate 65 cor-. 35 responds to the plate 46a in Mgure 5 but its stop forming element 65a is modifled tG accommodate the transversely disposed flange 66 of the angle forn-i.ing part of the front door edging 67 to form the stop element on the door. The rear post 40 plate 68 includes an offset portion 69 acting as a spark strip member and also as a stop for the projecting element 66 on the front of the door when the latter is opened. Figure 9 illustrates a modification in which the 45 spark and weather seal is rendered more effective by utilizing strips of rubber or like packing rnaterial 70 and 71 between metal portions of the door and post. This need not interfere with the use of the door rear post as a door stop and the 50 provision of a stop engaging element on the door. In this modification a stop element 72 on the rear door post Z-bar 73 projects outwardly from the side wall into the general plane of the door framing so as to be engaged by the plate 74 corre55 sponding to the plate 48 previously described. Other modifications in different details of construction may be made witbout departing from the spirit of the invention and I conteml)late the exclusive use of those variations which come 60 within the scope of my claims. claim, 1.

Company, Chleaco, ID., a corporation of IDinois Application October 5, 24 Claims. The invention relates to railway rolling stock and moreparticularly to box r-ar sliding doors and associated structure, although not limited exclusively to the same. It is a common practice to attach a relatively small door stop to a car side wall for the rear edge of the door to strike when it is opened. The railroads have considerable difficulty in maintaining these backstops. If the door Is not 10 properly secured in the closed position, especially if it is of the free rolling type, door movement during switching operations, for example, willfrequently tear off or badly batter the door back stop and sometimes damage the car walls to which is the stop is secured. If the stop is secured to the door track, the batteri@ of the door may bend the track out of alignment. F'requently the door itself is injured where the same contacts with the back stop due largely to the fact that the 20 blow from the back stop is concentrated on a small 'area of the door edge. In connection with extra wide doors of the type commonly used in "automobile" cars, it is customary to provide an auxiliary door in addi25 tion to the ordinary door, the auxiliary door having a post mounted thereon which may be locked to the car framing when the auxiliary door is in closed position. This auxiliary door post then becomes the front door post for the 30 ordinary door which may be-shut to close the remainder of the door opening. When the auxiliary door is opened, the objectionable fea tures referred to in the preceding paragraph ar; not only present but are likely to be accentuated 35 because of the increased weight of the door due to its carrying the auxiliary post. Frequently the auxiliary post locking mechanism is so located that when the auxiliary door is opened the mechanism is positioned to be injured by 40 the auxiliary door rear post on the body framing if the door stops referred to faU to function as intended. Also such location of the auxiliary door post mechanism tends to reduce the effective length of the door opening which can be obtained. 45 one object of the present invention is to provide a door and stop arrangement which will avoid the above mentioned difficulties. Briefly, this object is attained by utilizing the body post at the rear of the door opening as a stop and pror,o viding a member on the door for engaging the same to limit the moveinent of the door. In the usual car construction, the door unit, whether single or auxiliary door, including its front and rear edging members, overlies the door ..5 posts, the inner face of the door body being outside of the outer face of the post although the door and post may have supplementary spark and weather sealing elements overlapping each other transversely of the car. Since the over all Go width of the car, i. e., through the doors, can1933, Serial No. 692,229 (Cl. 20-22) not be exceeded because of clearance liinitations, the inside width of the car Is reduced by the thicknes s of the door unit and the thickness of the post and sometimes the sheathing thereon. It is another object of the present invention to 5 so form the door post and door body that they overlap each other transversely of the car, thereby making it possible to Increase the inside width of the car. Anoth er object of the invention is to provide 10 coacting door and post main elements of substantial thickness which will cooperate to form a secure spark and weather seal. It is further desired to maintain the maximum door opening irrespect ive of door and post parts provided for 1.5 the general purposes mentioned above. An additional object of the invention is to provide a novel mounting of the latching mechanism for an auxiliary door post so that the same will be protected from the auxiliary door rear post 20 and from shifting lading or other objects movable relative to the door and likely to injure the latching mechanism in its usual exposed location. Anoth er object is the provision of an improved latching device having a limited number of parts 25 and serving to lock the post at top and bottom independ ently but in which the operation of unlocking one latch will also unlock the other latch. Other incidental objects will be referred to in the following description of the structure shown 30 on the accompanying drawings, in whichMgur e 1 Is a vertical transverse section through the side sill, floor and side plate of a car at the door opening and showing the front edge of an auxiliary door and post, the section being taken 35 on the line 1-1 of Figure 3. Flgure 2 is an elevation of the structure shown in Flgure I looking from the inside of the car. Flgure 3 is a horizontal section through the door and door post construction and is taken sub- 40 stantially on the line 3-3 of Mgure 2. Mgur e 4 is an outside elevation of a portion of a car side structure including a single door. Figure 5 is a horizontal section on the line 5-5 of Mgure 4. 45 Mgur e 6 is a section through the 'right hand or rear door post in Figure 4 and showing the adjacent portion of the door when in open position. Mgur es 7, 8 and 9 are sections corresponding to Mgure 5 but Illustrating modified forms of 50 the invention. Fligur es I to 3 inclusive include the upper por- tion of a car side sill channel 1, a car floor 2, a door track Z-bar 3, a threshold plate 4, a side cornice plate Z-bar 5, and a door upper retainer 55 S. The main door is indicated at 7 and the auxiliary door at S. Fach of these doors is of st@el construction including Z-bar front and rear edging members 9, 10, 11 and 12 and panel sheets- 13 and 14 dished between the planes of (10

2 2,109,515 the Z-bar flanges which define the outer and Inner faces of the door bodies. The car franiing Includes the right hand door post 15 and the left band door post I S. Post 15 comprises an angle member I 5a, a plate I Sb and a wooden fuler I Se. The left hand post comprises a similar angle 16a, plate 16b and filler 16c. 'Me wall outer sheet 17 and the inner sheating I 8 are of ordinary construction and are secured to the framing in the 10 usual manrier. The auxiliary door post i 9 comprises a channel or U-shaped plate i 9a, riveted to the front edging I I of the auxiliary door, and a wooden fwer 19b whieb Is bolted to the longer leg of the plate 19a jr, and fllls but a part of the space between the legs of the plate 19a, leaving a substantial space withIn which the latching and uniatclilng bar 20 may be mounted. Plate 15b of the main door post extends out20 wardly beyond the outer face of the side wall . of the car to the inner face of the door and then is bent to parallel the car side and terminates l.n an offset flange 15d which projects Into the space between the inner and outer faces of the 26 door body. When the door Is closed, as indicated in full lines in Flgure 3, the rear edge of flange 15d is spaced from the web of the Z-bar 9 and a plat,e 21 secured to Z-bar 9 overlaps the inner face of flange I Sd to forin a sliding and yielding 30 contact of greater or less extent depending upon variations in the manufacture of the door and post and wall structure. Irrespective of such variations, the contact will be sufficient to insure 9, seal against weather, sparks, dirt, etc., and 35 without limiting the closing movement of the door. When the door is opened, as indicated In dotted lines In Flgure 3, the forward edging I 0 str4kes the offset flange 15d and the latter serves as a 40 stop fbr the door extending substantially throughout the, height of the latter and transmitting the blow from the door directly through the remainder of the post structure and through the latter to the car sill and plate. This elizni4r) nates the necessity of providing the usual car stops with possible damage to the car wall or door structure due to the bumping of such stops by the sliding door or to the failure of such stops altogether. It will be noted that the construc50 tion described does not reduce the effective width of the main door opening as the front edging 10 moves completely to the rear of the door opening as determined by plate i5b. The overlapping of the door 'and post strlic,5,5 ture, transversely of the car, makes it possible to reduce the over all distance, from the inside of the car to the outside of the door, below the minimum which could exist If similar post and door dimensions were used with the door framing over60 lying the outer face of the post in the usual manner. Hence, the Inside width of the car may be increased proportionat6ly. ' The above described construction and fimetion of the right hand post 15 and associated 6,5 main door structure applies also to the left hand door post 16 and the associated auxiliary door structure. The front edging I I of the auxiliary door It Is provided with a stop plate between Z-bar flange 70 and the U-plate 19a. The outer offset flange 22 on this stop plate cooperates with the auxiliary ,post plate 19a to forin a pocket for receiving and stopping the forward edging ID of the main door 7. 'Me inner flange 23 of the plate on edging I I 75 is spaced a short distance from the auxfliary door past and is disposed so as to abut against offset 16d of the main post when the auxiliary door is bpened, as indicated In dotted lines, thereby transmitting the blow of the door directly to the door post throughout It& length and through the latter to the car framihg. 'Mis eliniinates the necessity of providing a door stop on the side wall for the auxiliary door and the disadvantages arising from the use of the ordinary door stop. Also the stop flange 23 prevents the abutment of 1( posts 19 and 16 and the resulting tendency to twist the auxiliary post on the door, Injuring the latter and damaging the latching mechanism. The auxihary post is secured In door closing position at toP and bottom. A hook 24 is pivoted 15 to a housing and stop casting 25 secured to the side plate 5 and drops Into a hollow casting 26 @eated in the auxuiary door post and projecting above the top of the latter and engaging stop casting 25 to Iiinit the movement of the door. 20 The latching bolt 20 heis a squared lower portion 27 which fits Into a socket In a stop and latching -casting 28 seated in the car floor. A casting 29 in the auxillary door post guides the - lower portion of the latching shaft. Casting 29 also forms 26 a housing for and journals the post supporting roller 3 1. When the door ig moved to closed position, the lower end of shaft 20 will ride over the threshold !)late 4 until the socket -casting 28 is reached, 30 when it wili automatically drop into position, being supported by the shoulder S on the casting 29 and by the engagement of its upper offset portion 20a with the -ledge 26a on casting 26. At the same time the forward end of hook 24 35 will ride over the upper Guter edge of casting 26 and automatically drop into i3osition. When the door is to be opened, the latching shaft 20 may be dislodged by the handle 30. This'will free the interengaging elements at, the floor and at 40 the same time dislodge hook 24 to release the upper end of the post. This construction provides independent latchIng of the upper and lower ends of the post although retaining the desirable feature of a single 45 operation for unlatching both ends of the post when the door is to be opened. The construction described above provides a simple, economical and effective arrangement of door and post structure for extra wide openings in the car walls and 50 possesses the advantages Indicated by the statement of objects at the beginning of the speciflcation. However, many of the desirable features may be embodied in a single door construction as illustrated on the other drawings, and the post 55 and door constructiorl may be otherwise modified. In Flgures 4 to 6 the right hand door post 40 corresponds to post 15 previously described but the cooperating rear edging of the door consists 60 of an angle Iron 41 and a supplementary sealing element 42. Me door panel sheets 43 mount a rear plate 44 which cooperates with element 42 to yieldingly receive the flange 40c of the post plate 40a thus forming a sealing structure wlilch 65 may be more desirable. The front or left hand post 46 includes a plate 46a termihating in a pocket 46b facing towards the door opening and adapted to receive the flange of the door front 70 edging 47. A front reinforcing plate 48 extends from the door sheets 43 tG the outer flange of the front edging 47 and when the door is opened, as indicated In Figure 6, the offset portion 48a of this plate strikes against the offset portion 40c 75
