Company, Chicago, 111., a corporation of Illinois Application October 5, 1933, Serial No. 692,229 i 24 Claims. (CI. 20-22) The invention relates to railway rolling stock and more particularly to box car 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 di?iculty 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, will frequently tear off or badly batter the door back stop and sometimes damage the car walls to which 15 the stop is secured. If the stop is secured to the door track, the battering of the door may bend the track out of alignment. Frequently the door itself is injured where the same. contacts with the back stop due largely to the fact that the ” 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 addi 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 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 are 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 fail to function as intended. Also such location of the auxiliary door post mechanism tends to reduce the eifective length of the door opening which can be obtained. One object of the present invention is to pro 45 vide a door and stop arrangement which will avoid the above mentioned difficulties. Brie?y, this object is attained by utilizing the body post at the rear of. the door opening as a stop and pro viding a member on the door for engaging the same to limit the movement of the door. In the usual car construction, the door unit, not be exceeded because of clearance limitations, the inside width of the car is reduced by the thickness of the door unit and the thickness of the post and sometimes the sheathing thereon. It is another object of the present invention to so form the door post and door body that they overlap each other transversely of the car, there by making it possible to increase the inside width of the car. Another object of the invention is to provide 10 coacting door and post main elements of sub stantial thickness which will cooperate to form a secure spark and weather seal. It is further desired to maintain the maximum door opening irrespective of door and post parts provided for 15 the general purposes mentioned above. An additional object of the invention is to pro vide 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 mov able relative to the door and likely to injure the latching mechanism in its usual exposed location. Another 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 independently but in which the operation of un locking 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 which Figure 1 is a vertical transverse section through ' the side sill, ?oor 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 on the line l—-l of Figure 3. Figure 2 is an elevation of the structure shown in Figure 1 looking from the inside of the car. Figure 3 is a horizontal section through the door and door post construction and is taken sub stantially on the line 3—3 of Figure 2. 35 40 . Figure 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 Figure 4. 45 Figure 6 is a section through the right hand or rear door post in Figure 4 and showing the ad jacent portion of the door when in open position. Figures 7,18 and 9 are sections corresponding to Figure 5 but illustrating modi?ed forms of the invention. Figures 1 to 3 inclusive include the upper por whether single or auxiliary door, including its . tion of a car side sill channel I, a car ?oor 2, a front and rear edging members, overlies the door door track Z-bar 3, a threshold plate 4, a side cornice plate Z-bar 5, and a door upper retainer at) posts, the inner face of the door body being out side of the outer face of. the post although the 6. The main door is indicated at "l and the door and post may have supplementary spark auxiliary door at 8. Each of these doors is of and weather sealing elements overlapping each steel construction including Z-bar front and other transversely of the car.

The car framing ‘ - includes the right hand door post I5 and the left hand door post It. Post l5 comprises an angle member lia, a plate I51) and a wooden ?ller lie. The left hand post comprises a similar angle I60, plate lBb and ?ller I60. The wall outer sheet I‘! and the inner sheeting ii! are of ordinary con struction and are secured to the framing in the door past and is disposed so as to abut against offset “id of the main post when the auxiliary door is npened, as indicated in dotted lines, there by transmitting the blow of the door directly to the door post throughout its. length and through the latter to the car framing. This eliminates 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. 10 usual manner. Also the stop ?ange 22 prevents the abutment of 10 _ The auxiliary door post l9 comprises a channel posts I! and I6 and-the resulting tendency to or U-shaped plate Ha, riveted to the front edging twist the auxiliary post on the door, injuring the H of the auxiliary door, and a wooden ?ller lab latter and damaging the latching mechanism. which is bolted to the longer leg of the plate l9a The auxiliary post is secured in door closing 15 and ?lls but a part of the space between the legs position at top and bottom.

When the door is closed, as indicated in full lines in Figure 3, the rear edge of ?ange 15a’. is spaced from the web of the Z-b'ar 9 and a plate 2| secured to Z-bar 9 overlaps the inner face of ?ange l5d to form 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 a 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 Figure 3, the forward edging I0 strikes the offset ?ange lid and the latter serves as a 40 stop for the door extending substantially throughout theheight of the latter and trans mitting the blow from the door directly through the remainder of the post structure and through the latter to the car‘ sill and plate. This elimi 45 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 construc 50 tion described does not reduce the effective width of the main door opening as the front edging I0 moves completely to the rear of the door open ing as determined by plate lib. , The overlapping of the door and post struc 55 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 mini mum which could exist if similar post and door dimensions were used with the door framing over 60 lying the outer face of the post in the usual man ner. Hence, the inside width of the car may be increased proportionately. ' The above described construction and func tion of the right hand’post l5 and associated 65 main door structure applies also to the left hand door post I6 and the associated auxiliary door structure. , 21 which ?ts into a socket in a stop and latching casting 28 seated in the car ?oor. A casting 29 in the auxiliary door post guides the-lower por tion of the latching shaft. Casting 29 also forms a housing for and journals the post supporting roller 2|. When the door is moved to closed position, the lower end of shaft 20 will ride over the threshold plate 4 until the socket casting 28 is reached, when it will automatically drop into position, being supported by the shoulder S on the casting 29 and by the engagement of its upper offset portion 2011 with the ledge 26a on casting 26. At the same time the forward end of hook 24 35 will ride over the upper outer edge of casting 26 and automatically drop into position. 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 ?oor and at 40 the same time dislodge hook 24 to release the upper end of the post. ' This construction provides independent latch ing of the upper and lower ends of the post al though retainlng 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 struc ture for extra wide openings in the car walls and possesses the advantages indicated by the state ment of objects at the beginning of the speci?ca tion. 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 construction may be otherwise modi ?ed. In Figures 4 to 6 the right hand door post 40 corresponds to post l5 previously described but the cooperating rear edging of the door consists of an angle iron 4| and a supplementary sealing element 42. The door panel sheets 43 mount a rear plate 44 which cooperates with element 42 to yieldingly receive the ?ange 400 of the post plate 40a thus forming a sealing structure which 65 may be more desirable. The front or left hand The front edging ll of the auxiliary door 8 is _ post 46 includes a plate 46a terminating in a. provided with a stop plate between Z-bar ?ange pocket 46b facing towards the door opening and 70 and the U-plate I911. The outer o?’set ?ange 22 adapted to receive the ?ange of the door front 70 on this stop plate cooperates with the auxiliary edging 41. A front reinforcing plate 48 extends post plate I911 to form a pocket for receiving and from the door sheets 43 to the outer ?ange of stopping the forward edging III of the main door the front edging 41 and when the door is opened, ‘I. The inner ?ange 23 of the plate on edging H as indicated in Figure 6, the offset portion 48a 75 is spaced a short distance from the auxiliary of this plate strikes against the offset portion 40c 75 2,109,515 ' of the rear post plate which forms a stop for the door as previously described. ‘ opening and the element on the door being adja ~ Figure 5 illustrates the application of a grain door 49 to the post structures, the latter being recessed at their inner corners to accommodate the grain door with the inner face of the latter ?ush with the inner side wall of the car. In the modi?cation illustrated in Figure '7, door posts 50 and 5| are of Z-section with portions 10 of the ?anges nearest the outer face of the 'car bent inwardly, as at 52, the wooden portions 53 of the posts being recessed at their outer oppos ing corners to receive ?anges 52; The door comprises ?at body panel plates 54 15 having a W-shaped front edging 55 and a Z shaped rear edging 56 and transverse reinforce ments 51. The inwardly extending lip 58 on the front edging 55 projects inwardly of the inside cent the front edge of the door so that the door when opened may move to a position to fully clear the door opening. . 3. A construction as speci?ed in claim 1 in 5 which the interengaging elements extend sub stantially throughout the height of the door whereby the shock of arresting the door move ment is distributed over substantially the entire door structure. .40 4. In a railway car, a wall having a door open ing and a post at the rear of said opening, a door having front and rear edglngs, there being a. member on said post cooperating with said door rear edging to form therewith a spark and 15 weather seal when the door is closed and co operating with said front edging to limit the opening movement of the door. 5. In a railway car, a wall having a door open ~ ing and door posts at the front and rear of said 20 20 the inturned ?ange 52 of the front post to limit plane of the door proper so as to abut against the closing movement of the door and to abut against the inturned ?ange 52 of the rear post to limit the opening movement of the door. A spark strip 59 on the front door post 5| co 25 operates with the forward portion of edging 55 to form a front seal, and cooperating strips 60 and 6| on the rear post 50 and the rear door edging 56 cooperate to form a rear seal. The recesses in the outer opposing corners of the posts permit the forward portion of edging 55 to move beyond the limits of the door opening X so that the latter is in no ways restricted by the inter opening, each post including a weather seal ele ment, a sliding door including a body panel over lying the outer faces of said door posts' and also including an inward-projection arranged to abut against said elements as the door is closed or 25 gpened respectively to limit the movements of the Ooh . , 6. In a railway car, a wall having a door open ing and door posts at the front and rear of said opening, each of said posts including a Z-bar with 30 its web disposed transversely of the wall and with the edge portion of its outer ?ange turned in wardly from the outer face of the car wall, a engaging door and post parts. In Figure 8, the front door post plate 65 cor-_ sliding door including a body panel overlying at 35 responds to the plate 46a in Figure 5 but its stop least one of said outer ?anges and also including 35 forming element 65a is modi?ed to accommodate an inward projection arranged to abut against' the transversely disposed ?ange 66 of the angle forming part of the front door edging 61 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 modi?cation in which the 45 spark and weather seal is rendered more effective by utilizing strips of rubber or like packing ma terial 10 and 1| 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 modi?cation a stop element. 12 on the rear door post Z-bar 13 projects outwardly from the side wall into the general plane of the door'fram ing so as to be engaged by the plate 14 corre 55 sponding to the plate 48 previously described. Other modi?cations in different details of con struction may be made without departing from the spirit of the invention and I contemplate the exclusive use of those variations which come within the scope of my claims.
