This invention relates to side door construction utilized upon freight cars and concerns itself primarily with the auxiliary door of the double door construction of automobile freight cars and, more particularly, with the post structure employed upon such auxiliary doors.

It is an object of this invention to providea side door for freight cars having a jamb or post mounted for swinging movement thereon.

A further object is the provision of a side door having a post swingingly mounted adjacent the forward edge of said door and adapted to lock said door in closed position.

Another object is the provision of a car side door provided with a swinging post adapted for engagement with upper and lower portions of said car whereby said post serves both as a tie and as a strut for said car ina predetermined position of the door.

An object, also, is the provision of a car side door having a post releasably mounted for swinging movement thereon.-

It is a further object of this invention toprovide a side door having secured thereto a post or jamb which is readily removable from the door,

'whereby said door may be removed from the car without the necessity of removal of the supporting track for said door.

A further object is the provision of a side door having a swinging post, brackets being secured to said door andsaid post, respectively, for supporting the post upon the door, said brackets serving to limit the angular displacement of said post. A further object is the provision of a post mounted upon a side door for swinging movement in a plane parallel to the door, the post in its projected or operative position securing the door against transverse and longitudinal movements relative to the car. 7

Another object is the provision of a swinging post for side doors serving to reinforce said doors against bulging stresses.

Further objects will become apparent as the description of the invention proceeds.

Figure 16 is a side elevation of a part of the mounting shown in Figure 11 which is secured to the door.

Figure 17 is a front elevation of the structure shown in Figure 16. 35 In loading automobiles or other bulky lading into railway freight cars the sides of these cars are provided with openings which are exceptionally wide and which are covered by means of two sliding doors, these doors in their opening move- 40 ment traveling in opposite directions. The exceptional width of door opening leaves quite a large unsupported span substantially in the center of the sides of the cars. In order to reinforce the sides of the cars in the door open- 45 ings reinforcing posts or jambs have been utilized, which posts or jambs are customarily applied to one of the double door, usually designated the auxiliary or supplemental door. In the closed position of this door the post or jamb is 5 interlocked with the, sub-structure and superstructure of the car in order to tie these parts together to prevent their spreading when the car is subjected to impact and, furthermore, to serve as a strut to avoid relative movement of these parts toward each other. The jambs or posts heretofore employed have been of two kinds, namely, jambs which have been rigidly secured to the supplemental door for movement therewith and those which are capable of movement independently of the supplemental door. The latter type of jamb or post, because of its loss from the car, has proved unsuccessful. The post or jamb which is secured to the door for movement therewith has in the main been satisfactory for the purpose indicated above and, also, for relieving the supplemental door to which the post or jamb is secured from stresses tending to bulge said door outwardly. With the latter type of post or jamb, however, it has been found to be impossible to remove the supplemental door from the car side or to remove the post or jamb from the door without first taking off the track upon which the door is supported or removing the supporting hangers or the top retainer customarily employed with said door. According to the instant invention there is provided a jamb or post construction for the supplemental door of a double door freight car capable of serving both as a strut and as a tie for said door, which is readily applicable and releasable from the door, which serves as a reinforcement for the door against bulging stresses and which, upon removal from the door, permits said door to be slid off the track without disturbing the track or fixtures applied to the car and to the door with the exception of the stops for the door.

Referring to the embodiment of the invention illustrated in Figures 1 to 10, inclusive, there is disclosed a railway house car I!) having exceptionally large door openings provided in the sides thereof, each of which openings is adapted to be closed by a plurality of sliding doors consisting of a main door II and an auxiliary door l2. As illustrated in the drawings these doors preferably are formed of metal and are provided with a plurality of corrugations I3 and I4, although it is to be understood that the invention is applicable to doors of construction other than that shown. Each of the doors is provided with a plurality of hangers I5 adapted'to support the door for sliding movement upon a track 6. The upper margin of the door is retained against outward movement from the car by means of a retaining bar 11.

The jamb or post I8 of the instant invention is mounted upon the auxiliary door l2 adjacent the forward edge thereof. Mounting of said jamb or post is effected by means of a bracket member i9 secured to the jamb and cooperating with a bracket member 26 fastened to the door 12. The bracket member l9 comprises a base portion 2| by which the bracket is adapted to be secured to the jamb and the projecting hollow boss 22. The bracket member 26 secured to the door is provided with flanges 23 by means of which said bracket is secured to the door and with a projecting hollow lug 24 adapted to be'received within the hollow boss 22 provided on the jamb racket member. Extending preferably at right angles from the lug 24 provided on the door bracket member is a. lobe 25 adapted in the operative assembly of the two bracket members to be positioned within the hollow boss 22 formed on the jamb bracket member. An extension 26 is provided on the bracket member l9, this extension in the projected position of the jamb when the supplemental door is closed having overlapping relationship with the bracket member 29 secured to the door. It will be observed plane after the jamb bracket member and the door bracket member have been secured in proper position engagement between the boss 22 and lug 24 may readily be effected. After such engagement the jamb may be locked in position upon the door by rotation of said jamb through an angle of ninety degrees so that it assumes a substantially vertical position. Disengagementof-the bracket members, and consequently of the jamb from the door, will then be avoided because of the engagement of the lobe 25 within the boss 25 provided on the jambbracket member. As a further'protective measure it is preferred that a rivet 28 passing through the jamb, the door and the boss and'lug provided on the bracket members be employed to prevent disengagement of the jamb from the door; It will be apparent, furthermore, from a consideration of Figures 1 and 6 of the drawings that the jamb may readily be rotated in a counterclockwise direction as viewed in Figure'l but that its rotation in a clockwise direction will be resisted by engagement of the projection 26formed'on the jamb bracket member and the bracket member secured to the door.

In order to lock the jamb and consequently the door to which it is applied in closed position keepers 29 and 30 are provided. The keeper 2!! is secured to the car above the jamb'while the keeper 30 is secured to the car below the jamb. The keeper29 is provided with a base or attaching portion 31 from which 'depends'a portion having a latch receiving recess 32. The latch receiving recess is open at one end as indicated at 33 and the opposite end thereof is provided'with 4 Extending inwardly in horizontally posiclosed by means of a wall fl at its opposite end.

Inwardly directed flanges 4| and 42 extend into the latch receiving recess 38. The lower keeper 30 is provided additionally witha bolt receiving recess 43 which is approached by means of an inclined wall 44.

Thejamb i8 .ispreferably provided at its, upper and lower ends with latches. 45 and 46, respectiveiy. Each of these latches is provided with an enlarged head asindicated at ,4? and 48 which. in the projected position of the jamb, are adapted to beseat d Within the latch receiving recess of their respective keepers in overlapping relationship with the inwardly directed flanges provided on said keepers. The-lower end of the jamb is additionallyprovided with a locking bolt 49 mounted upon the jamb by means of a'bracket member 59 within which the bolt is capable of reciprocable movement. The lower end of the locking bolt in the projected position of th'ejamb is adapted to be received within the bolt receiving recess 43 provided in the lower keeper 3%).

It will be apparent from the foregoing detailed description that when the supplemental door is in its closed position and the jamb or post mounted upon said door is in the projected or looking position that said jamb through the latches 45.

and 56 will have locking engagement with the keepers 29 and 38 mounted, respectively, above and below said jamb. In such locking engagement the enlarged head portions on the latches 45 and 46 will lie in overlapping relationship with the inwardly directed flanges provided on the keepers. Additionally, the locking bolt 48 will assume its projected position and lie within the bolt receiving recess 43 provided in the lower keeper. It is evident that the supplemental door is incapable of movement either longitudinally or transversely of the car. Moreover, the overlapping relationship of the enlarged heads provided on the latch members secured to the jamb and the inwardly directed flanges provided on the keepers will tie' together the upper and lower parts of the car within the door opening and the jamb, which is clearly illustrated as a sturdy member, will resist tendency of the upper and lower parts of the car at the door opening from approaching each other. It is also clear that the pressure of lading within the car against the jamb will be resisted by the jamb without transmitting said pressure to the door. In order to release the door for sliding movement toward its open position the locking bolt 59 is retracted and the jamb or post is swung in a counter-clock- Wise direction as viewed in Figure 1 until said jamb clears the keepers. The supplemental door may then be moved to its open position. In such position the jamb will assume its normal vertical position. In the closing movement of the supplemental door the jamb will again be swung to the position indicated in Figure l and the door moved to its closed position. The jamb is then swung to vertical position, whereby the latches provided on the jamb will operatively engage the keepers provided on the car. During this swinging movement of the jamb the lock bolt 49 will engage the inclined wall 44 provided on the lower keeper and will automatically be raised so that when the jamb takes its final closing position said locking bolt will drop into the bolt receiving recess 43.

In Figures 11 to 17, inclusive, of the drawings there is disclosed a further embodiment of another preferred form of the instant invention. The jamb or post I8 is provided with a bracket member secured thereto-through the flanges 52. The bracket member 5| is provided with a base portion 53 from which extends a cylindrical boss 54, the end of which is preferably formed with an angular extension 55. Secured to the door exteriorly thereof is a bracket member 56 having the attaching flanges 51' from which extends a hollow housing member 58. In the mounting of the jamb or post l8 upon the supplemental door [2 disclosed in Figure 13 of the drawings the cylindrical boss 5i formed on the jamb bracket member 5| extends through the door and within the hollow housing member 58 formed on the bracket member 56. Engagement between the bracket members is effected when the jamb is in substantially horizontal position so that registry between the flange 55 provided on the boss 54 with the recess in the housing member 58 is had. The jamb is then rotated through an angle of ninety degrees until it assumes a substantially vertical position whereupon the flange 55 will extend across the recess provided in the housing member 58 and engage the wall thereof so as to prevent release of the jamb from the door. This fact is clearly illustrated in Figure 12 of the drawings. It is preferred, in order to avoid accidental disengagement of the jamb from the door, to employ a rivet 59 extending through the door, the jamb and the bracket members as clearly shown in Figure 13 of the drawings. It will be clear that the jamb is mounted upon the door in the instant embodiment of the invention for swinging movement relative thereto. The construction of the jamb may be similar and its locking engagement with the door the same as in the first embodiment of the invention disclosed. In the embodiment of the invention considered, however, it will be apparent that by taking out the rivet 59 and disengaging the jamb from the door the rear or inward surface of the door is substantially plane so that no obstacle is presented upon the door which may engage the rear door post 69 in the opening sliding movement of the door. In View of this fact the door in such sliding movement may be disengaged from the 5 car without the necessity of removing the door or car fixtures.

It is apparent that numerous modifications and changes may be effected in the embodiments of the invention disclosed without departing from o the spirit thereof. It is intended, consequently, that all such modifications and changes be comprehend-ed within the invention, which is to be limited only by the scope of the appended claims.
