Our invention relates to railway cars and more particularly to gondola cars of the type in which the ends thereof are in the form of doors arranged to be swung inwardly and downwardly at right angles to their normal positions to permit of the loading of material of greater length than the car.

A principal object of the invention is to provide improved mechanism for maintaining these doors, which are commonly known in the art as drop end doors, in a substantially upright or closed position.

Another object of the invention is to provide simple and rugged means for preventing spreading of the side walls of the car.

A primary feature of the invention consists in equipping the car with a plurality of brackets, one of which is mounted on an upper' corner of the door and the other on an adjacent portion of the adjoining side wall of the car, one of the brackets having movably mounted thereon a member adapted to cooperate with the other bracket to maintain the door in closed position.

Another feature of the invention consists in arranging the movable locking member so that it will be disposed betweenone side of the drop end door and the adjacent side wall of the car.

Another feature of the invention consists in associating with the movable member means for looking it in operative position.

A further feature of the invention resides in forming the bracket members with portions adapted to be brought into interlocking relation to prevent spreading of the side walls of the car.

A still further feature of the invention consists in arranging the corner posts of the car so as to limit outward movement of the drop end doors.

Other and more specific features of the invention residing in advantageous forms, combinations and relations of parts will hereinafter appear and be pointed out in the claims.

Figure 15 is a side elevational view of the bracket illustrated in Figure 13 as viewed from the left-hand side thereof.

Figure 16 is a diagrammatic end view of the gondola car.

While the drawings illustrate in detail only a portion of the side wall of the car adjacent the end of the latter and the adjacent portion of the co-acting drop end door it is to be understood that the construction is duplicated at the opposite end and the opposite side of the car, that is, the mechanism illustrated in detail for maintaining the end door in closed position is one of the two employed for each door.

Referring more particularly to the drawings l-I indicates the side walls of the car and 2 one of the drop end doors which is hingedly connected along its lower edge to the car body in any suitable manner (not shown) so as to swing inwardly at substantially right angles to its normal upright position to permit the loading of material of greater length than the car.

While the door may be constructed in any convenient manner and of any desired material the one chosen for purposes of illustration is of sheet metal having inwardly projecting top and side marginal flanges 3 and 4, respectively. Likewise, the side walls of the car, although wooden ones have been illustrated, may be formed of any suitable material. Extending along the upper edges of the side walls are top rails 5, each of which may advantageously be formed with a substantially horizontally disposed leg or flange 6 and a substantially vertically disposed leg or flange l.

The outer edge of the horizontal flange 6 may, if desired, be formed with a rigidifying rib or head 8.

At their ends the side walls are preferably reinforced by a plurality of angularly shaped members 9 and I 0, respectively. The angle member 9 is formed with a leg or flange, I I which projects outwardly from the wall and with a flange or leg I2 which overlaps the outer side of the latter and the depending leg I of the side top rail, being preferably secured to the latter by rivets I 3. The angle member ID, which may be considered as a corner post, is formed with flanges or legs I4 and I5, respectively, the former being overlappingly secured to the leg I2 of the angle member 9 by one of the rivets I3 and one or more additional rivets I 6 and the latter being arranged to overlapthe outer face of the end door so as to limit outward movement of the latter when supported in upright or closed position.

Movably mounted on the side wall in overlapping relation to the inner face thereof and operablein a plane substantially parallel therewith is a member I'I adapted to be disposed in the path of inward movement of the end door. This member is preferably formed with a plate portion having spaced flanges or ribs I8 and I9 projecting laterally from its outer face for respectively coopcrating with the door to maintain the latter in partially closed and fully closed positions. To strengthen the flanges I8 and I9 and to rigidify the member I! the marginal edges of the latter may be provided with reinforcing flanges 20 and 2I, respectively, which preferably decrease in width from the flanges to the inner end of the member. The flanges I8 and I9 may be further strengthened by the rib I8 which may conveniently connect the upper portion of the flange I8 and the lower portion of the flange I9.

Each side of the door adjacent the upper portion thereof is provided with a ledge or shoulder 22 for cooperating with the flanges I8 and I9, respectively, of the movable member IT. This ledge 22 may be conveniently formed integral with a bracket 23, which is preferably of cast metal and has a plurality of plate- like portions 24 and 25 respectively secured by rivets 26 and 21 to the top and side marginal flanges 3 and 4 of the door. In order to rigidly tie these portions of the bracket together the latter is also fashioned with a portion 28 which overlaps the outer face of the main body portion of the door. The portion of the flange 4 to which the bracket is secured is offset inwardly to provide a recess 25, so that the ledge 22 and the adjoining parts of the bracket will not prevent inward movement of the door and free movement of the locking member between the side of the door and the adjacent portion of the side Wall. It will be appreciated that, in addition to serving as means for cooperating with the movable member to maintain the door in closed position, the bracket also serves to reinforce and strengthen that portion of the door to which it is attached.

Mounted upon the side wall of the car is a bracket member 29 having angularly disposed plate- like portions 38 and 3|, which respectively overlap the upper surface of the horizontal flange of the side top rail and the inner surface of the depending or vertical leg of the top rail. The portion 39 may be conveniently secured to the top rail by rivets 32 while the portion 3I is secured thereto by the rivets I3 and an additional rivet 33. Projecting laterally from the portion 3| of the bracket and preferably formed integrally therewith is a trunnion 34 affording a pivotal support for the movable member IT. A washer 35 may be conveniently employed for preventing the member I? from accidentally slipping off of the trunnion, the washer being held in place by the attaching rivet 33.

As the side walls of the car tend to spread due to lateral forces exerted by granular and other lading which may be carried in the car when the door is in closed position, it is desirable to provide means for interlocking the side walls and door to insure proper cooperation of the locking members I! with their cooperating ledges 22. For this purpose the bracket 29 may advantageously be provided with a hood or inwardly projecting portion 38 which terminates in a downwardly extending lug or projection 37 adapted to engage the inner face of an upwardly extending lug or projection 38 integrally formed with the bracket 23'. It will be observed that the hood portions of the brackets close the spaces between the side walls and the side edges of the door and that they also overlie the major portions of the locking members I! thereby protecting them from injury. Since the side walls may spread when the doors are in open position, that is, when they are in overlapping relation with the floor of the car, the cooperating surfaces of the lugs 31 and 38 are respectively fashioned with beveled or inclined surfaces 39 adapted to coact with each other as the door is being moved toward closed position to draw the side walls inwardly whereby proper engagement of the lugs 31 and 38 is assured. If desired the lug 38 may be reinforced at its inner end by a triangularly shaped rib or flange 40 and in order to strengthen and rigidify the inwardly projecting portion 36 of the bracket 39 it may be conveniently connected to the horizontal portion 30 of the bracket by a plurality of ribs or flanges 4I. perceived that not only is simple and rugged means provided for preventing spreading of the side walls of the car and consequently accidental disengagement of the locking members I! from their cooperating ledges 22 by lateral movement of the locking members but means is also provided for drawing the side walls inwardly to insure proper cooperation of the various parts of the mechanism. The means for drawing the side walls inwardly, however, forms no part of this joint invention and it is fully described and claimed in the William E. Wine patent Number 1,853,248, dated April 12, 1932.

In order that the movable member I! may be conveniently operated from the outside of the car to permit the end door to swing inwardly, its free end projects outwardly as at 42 beyond the end of the car through a slot 43 formed in the upper portion of the leg I5 of the corner post ID. This outwardly projecting portion 42 of the member I! also affords a convenient means which may be engaged by a suitable keeper, such as the cam 44, for maintaining the member in operative position and thereby preventing it from moving accidentally to inoperative position. The cam may be conveniently pivotally mounted upon a trunnion 45 which projects outwardly from the end wall 48 of the bracket 29. By mounting the cam in this manner it may operate in a plane normal to the plane of operation of the member I I and engage the upper edge of the member which may be reinforced by a flange 2U constituting a prolongation of the flange 28. Washers 41 may be interposed between the cam and a rivet 48 which extends through an aperture 48' Thus it will be 40 in the trunnion 4G for preventing the cam from accidentally slipping off its trunnion.

The end wall 46 of the bracket 29 is formed with a depending portion 49 having an aperture 5B for receiving a rivet 5| to rigidly attach the bracket to the upper portion of the slotted leg l5 of the corner post. In this manner it will be perceived that outward bending of the slotted portion of leg i5 is effectively prevented. It should be noted that the portion of the corner post secured to the bracket 29 is offset, as at 52, to accommodate the portion 28 of the bracket 23 which overlaps the main body portion of the door.

Considerable difficulty is often experienced in causing drop end doors to assume a fully upright or closed position, due to distortion and def ormation thereof and also due to the lodgement of small pieces of lading between the door and the overlapping leg of the corner post. To minimize this difficulty the bracket 29 is formed with suitable means affording a fulcrum for a removable lever 53 which may be employed to obtain sufficient mechanical advantage for forcing the door into fully closed position. This fulcrum means may comprise an aperture 54 formed in the portion 3! of the bracket 29 which overlaps the inner face of the side wall of the car. The lower portion of the aperture is preferably bounded by an outwardly projecting flange 55 to provide sufficient purchase for the lever. This flange may be extended, as at 56, to form an abutment adapted to engage the underside of the pivoted member ll to maintain or support it in an elevated position when not in operative cooperation with the door.

When the door is moved from its lowered or open position to its upright or closed position the lugs 38 on the brackets 23 at the upper corners of the door are brought into engagement with the lugs 31 of the brackets 29 on the side walls. In this manner spreading of the walls will be prevented when the door is in closed position and it is to be noted that should slight separating or spreading of the upper portions of the side walls occur while the door is in open position, the co -action of the bevelled faces 39 upon initial engagement of the lugs 31 and 38 will bring the side walls back into their normal positions. About the time the lugs engage each other the ledge 22 on the door engages the bottom edge of the pivoted member H, which theretofore has been supported in an elevated position by the stop 56, causing the same to rotate upwardly until the ledge comes opposite the flange l8 at which time the member will gravitate downwardly bringing the flange into engagement with the ledge to maintain the door in a partially closed position. Continued movlement of the door will again cause the member to rotate up wardly due to the co-action between the flange l8 and the ledge until the latter is opposite the flange [9 at which time the member will again move downwardly under the influence of gravity whereby the ledge and flange l9 cooperate to maintain the door in fully closed position. Of course, should difficulty be encountered in moving the door to fully upright position the removable lever 53, heretofore described, may be employed. After the flange l9 engages the ledge 22 the cam 44 may be rotated into engagement with the outer end of the member I! to prevent accidental unlocking movement of the latter. The extreme outer end of the member I! may be fashioned with an upwardly projecting lug 51 so that in the event of undue wear between the cam and its pivotal support disengagement of the member and cam by accidental movement of the latter in the direction of its pivotal axis is prevented.

To permit the door to be swung inwardly to occupy a position at substantially right angles to its upright position the cam 44 is rotated in a counter-clockwise direction, as viewed in Figure 2, and the member I! moved upwardly out of engagement with the shoulder 22. It will of course be appreciated that should difiiculty be encountered in effecting rotation of the movable member I! either to move it into or out of engagement with the shoulder 22 the outwardly projecting end of the member affords a convenient means which may be struck by a hammer, crow bar or the like. In order that it will not be necessary for the operator to maintain the cam in an elevated position to prevent it from interfering with free pivotal movement of the member II, the cam is fashioned with an elongated portion 58 adapted to contact with a side of the member after the cam has been rotated in a counter-clockwise direction out of engagement with the latter.

From the foregoing it will be perceived that simple, rugged and reliable means has been provided, which in addition to preventing spreading of the side walls of the car, serves to maintain the drop end door in an upright position.
