54 Claims.

My invention relates to railway cars and more particularly to that type commonly known as drop end door gondola cars. As is well known the ends, hereinafter called doors, of this type of car are movably mounted so that they may be disposed either in overlapping relation with the floor of the car to permit the loading of material of greater length than the car or in substantially upright positions to perform the normal functions of. car ends. When the end doors overlap the floor of the car they are considered as being in open position and when they are disposed substantially upright they are considered as being in closed position.

The principal object of the invention is to provide improved means for maintaining the doors in closed position.

Another object of the invention is to provide improved means for movably associating the doors with the car.

A further object of the invention is to provide means for drawing the side walls of the car inwardly as the doors assume closed position.

A still further object of the invention is to provide means affording a fulcrum whereby a removable lever may be used to force the door towards closed position and to draw the side walls of the car inwardly.

A still further object of the invention is to provide an improved corner post particularly applicable to this type of car.

A primary feature of the invention consists in forming the side walls of the car with rigid portions adapted to cooperate with means rigid with the door for pivotally associating the door with the car.

Another feature of the invention consists in providing the door with members adjacent the side edges thereof adapted to cooperate with means secured to the side walls of the car for pivotally associating the door with the latter, said means being so formed as to permit withdrawal of the door from the car.

A still further feature of the invention resides in providing a drop end door gondola car with corner posts having portions rigidly secured to the horizontal and vertical legs of the adjacent side top rails.

A still further feature of the invention resides in integrally forming the corner posts with improved means adapted to interlock with the door when the latter is in closed position to prevent spreading of the car sides.

A still further feature of the invention consists in providing the car with a plurality of pairs of members, one member of each pair being provided with a beveled surface cooperable with the other member of its pair whereby when the door is moved toward closed position said pairs of members are adapted to draw the side walls inwardly.

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.

Figures 10, 11, and 12 are enlarged sectional views taken respectively on lines III-Ill, III I, and l2-I2, Figure 1.

Figures 13 and 14 are elevational views of the corner post.

Figure 15 is a fragmentary longitudinal sectional view of the car showing the door in open position.

Figures 16, 17, and 18 are horizontal sectional views of one of the corner posts and adjacent portions of the end door, showing the latter in different positions of closure.

While the drawings illustrate in detail the construction of the ,car adjacent only one corner thereof it is to be understood that the construction is duplicated at each corner and that the mechanism illustrated for maintaining the door in closed position is only one of the two employed for each door.

Referring more particularly to the drawings I indicates one of theside walls of the car which in the present embodiment of the invention convertical flange 5, the latter being rigidly securedto the longitudinally extending plate 3 in overlapping relation to its inner face.

, Secured to the bottom plank or board of the car siding by a suitable means, such as bolts 1, is a longitudinally extending angle-shaped member having a vertical flange 6 overlapping the outer face of the siding, and a horizontal flange 3 which extends inwardly and underlies the floor 9 of the car which, like the car sides, may also be of wood. Extending beneath this angle-shaped member is a channel member ID having a substantially vertical web II and upper and lower inwardly projecting flanges I2 and I3, respectively, the former being rigidly secured to the flange 8 of the angle member. Thus, each side sill of the car is formed of two parts, namely, the angle-shaped member which preferably terminates inwardly of the end walls of the car and the channel-shaped member which preferably projects a short distance beyond the latter.

The wooden floor 9 may conveniently rest upon a top cover plate l4 of the car center sill which, in addition to this plate, is formed by spaced longitudinally extending beams I5. The center sill, like the channel-shaped member of the side sill, projects beyond the end Walls of the car and the projecting ends of these sills are connected by an end sill I6 which is preferably of angleshape and has an upwardly projecting substantially vertical flange l1 and an outwardly projecting substantially horizontal flange l9. The flange l8 rests upon the upper flange |2 of the channel member l and upon the top cover plate l4, being secured to the flange by rivets I9 and to the plate by rivets 20.

Secured to the side wall of the car is a corner post 2| which may advantageously be of T-shape, the stem of which extends longitudinally of the car while the flange thereof extends transversely.

The stem is formed with relatively

offset portions

22 and 23 connected by a preferably horizontal portion 24, the upper surface of which is in the plane of the upper surface of the top board of the siding. The lower portion 22 of the stem of the corner post overlaps the outer face of the siding and is secured thereto by a plurality of bolts 25. This portion of the stem of the corner post also overlaps the outer faces of the vertical flange 6 of the angle member and the web ll of the channel, being secured to these parts by

rivets

26 and 21, respectively. The upper portion 23 of the stem overlaps the irmer faces of the metal plate 3 and of the depending or vertical flange of the side top rail. To properly space the plate 3 from adjacent portions of the stem 23 the latter is integrally formed with a plurality of outwardly projecting bosses 28 which abut the inner face of the plate and are provided with apertures for receiving connecting rivets 29. Furthermore, the portion of the stem 23 immediately adjacent the flange 5 of the top rail is formed with bosses 30 which abut the inner face of the latter. These bosses are likewise formed with apertures to receive rivets 3| for connecting the corner post and top rail.

One portion of the flange of the T-shaped corner post projects inwardly from the stem thereof while the other portion of the flange projects outwardly from the stem, these portions being respectively designated by the

reference numerals

32 and 33. The outwardly projecting portion 33 extends slightly beyond the outer edge of the side top rail and its marginal edge is preferably provided with an inwardly projecting rigidifying bead or rib 34. Adjacent the top of the corner post the rib 34 decreases in width, as at 35, to form a relatively thin flange 36 which overlaps the outer end of the horizontal flange 4 of the top rail. Adjacent its lower end the outwardly projecting portion 33 preferably decreases in width to .a point adjacent the lower end of the corner post.

The inwardly projecting portion 32 of the flange of the corner post is adapted to overlap the outer face of the drop end door 31 and forms means for limiting outward movement of the door. To rigidify this portion of the flange it may be advantageously integrally connected to the stern by a plurality of substantially triangularly shaped ribs or flanges 38. As the wooden siding extends to substantially the portion 32 of the corner post, the boards constituting the siding are gained out or cut away to permit the flanges 38 to extend therebeyond. Above the wooden siding the inwardly projecting portion 32 of the flange is integrally connected to the stem of the corner post by a rib or flange 28 of somewhat less depth than the flanges 38. To further rigidity the corner construction of the car and in particular the inwardly projecting portion 32 of the flange of the corner post a plurality of angle shaped members 39 may be conveniently employed. These angle members are disposed on opposite sides of the reinforcing ribs 38 and each is fashioned with a leg or flange 40 overlappingly secured to the inner face of the wooden siding by the bolts 25 and with a leg or flange 4| overlappingly secured by rivets 42 to the inner face of the flange portion 32 of the corner post. Thus the flanges 4| of the angle members are interposed between the corner posts and door and are adapted to engage the outer face of the latter when it is in closed position. The inwardly projecting portion 32 of the flange extends somewhat beyond the inner edges of the flanges 4| of theangle members 39 and is preferably integrally formed with an inturned rigidifying rib or flange 43 which terminates substantially in the plane of the inner faces of the flanges 4| and is adapted to contact with the outer face of the door. As shown in Figures and 11 the

flanges

38 and 38 are formed with extensions 44 which are formed integrally with the inturned flange 43.

For a purpose that will hereinafter appear, the lower portion of the inwardly projecting portion 32 of the flange of the corner post is enlarged as at 45. This portion is disposed between the door and the upwardly projecting vertical flange ll of the end sill, being rigidly secured to the latter by a plurality of rivets 46. Where the flange I! of the end sill overlaps the corner post it is offset outwardly as at Il Although the stem of the corner post extends downwardly beyond the end sill for attachment to the channel member of the side sill the inwardly projecting portion 32 of the flange terminates adjacent the lower edge of the end sill.

At the upper end of the corner post the stem and outwardly projecting portion 33 of the flange are integrally connected by a substantially horizontal portion 41 which overlaps the upper face flange thereof.

of the horizontal flange or leg 4 of the side top rail and is rigidly secured thereto by a plurality of rivets 48. The inwardly projecting portion 32 of the flange is also integrally connected to the stem by a portion 48 and in order to reinforce the

portions

41 and 49 they may be formed with a plurality of upwardly extending ribs 58. From the foregoing it will be readily apparent that a corner post constructed in accordance with the foregoing description will, when applied to the car in the manner described, adequately and efficiently reinforce and rigidify the end portions of the side walls of the car.

While the drop end door 31 may be made of any desired material it is preferably fashioned from sheet metal and is integrally formed along its side and top edges with inwardly projecting marginal flanges 5| and 52, respectively. The upper edge of the door may be reinforced by an angle-shaped member 53 having a flange 54 secured by rivets 55 to the top flange 52 of the door and a flange 56 disposed in a plane spaced inwardly from and substantially parallel with the plane of the door. This top reinforcing member and the side marginal flanges 5| extend inwardly equal distances from the door so that when the door is in open position they may engage the floor of the car to support the door in a substantially horizontal plane. The lower portion of the door is also provided with a reinforcing member 51 which mayadvantageously be a bulb angle. One flange or leg 58 of this angle extends inwardly from the door for the same distance as the top reinforcing member and side flanges of the door so that it may also engage the floor of the car when the door is in open position. The other leg or flange 59 of the member 51 extends downwardly from the flange 58 in a plane parallel with that of the door, being secured to the inner face of the latter by rivets 60. The free edge of this last-named flange preferably extends beyond the bottom edge of the door and is enlarged to form the bulb 6|. The inwardly projecting flange 58 may advantageously be rigidly connected to adjacent portions of the side flanges 5| of the door by angle brackets 52. One leg of each angle bracket is secured to the inner face of the adjacent side flange by rivets 63 while the other leg thereof is secured to the lower face of the flange 58 by rivets 64. In this manner a very rigid door structure is produced and one which when in open position is supported on the floor of the car in a substantially horizontal plane so that material resting thereon will not tend to warp and distort it.

For movably associating the end door with the car the lower reinforcing member 51 is rigidly provided with means which preferably projects beyond adjacent portions of the side edges of the door. In the present embodiment of the invention this means is formed integral with the reinforcing member and comprises the bulb portion 6| which constitute trunnions 85. Although any suitable means may be rigidly secured to the side walls or floor of the car for cooperating with the trunnions 65 it is preferred to integrally form the lower portion of each corner post with a wall 86 spaced inwardly from and substantially parallel with the inwardly projecting portion 32 of the Thus the wall 86 and the adjacent portion of the flange of the corner post form a housing or slot into which the adjacent trunnion of the door may extend. The wall 68 and the adjacent portion of the flange 32 are preferably integrally connected by a portion 81 which extends parallel with and inwardly of the stem of the corner post and constitutes the end wall of the housing whereby substantial movement of the door transversely of the car is prevented. At its upper portion the wall 61 may advantageously be integrally connected to the stem of the corner post by a substantially horizontal portion 68.

To support the lower corners of the door when it is disposed in closed position each corner post may be formed with a horizontally disposed portion 69 upon which the associated trunnion of the door is adapted to rest. This portion 69 extends between the inwardly projecting portion 32 of the flange of the corner post and the wall 86 and serves to connect the lower portions of the latter and the wall 61 to the flange. The horizontal portion 89 is preferably provided with downwardly projecting extensions 18 and H, the latter constituting a continuation of the wall 61, which terminate at the lower edge of the inwardly projecting portion 32 of the corner post and engage the upper surface of the inwardly projecting horizontal flange 8 of the angle member of the side sill. At its central portion the lower edge of the door rests upon and is supported by a bracket 12 which forms a part of the car floor and has lateral extensions 13 secured by rivets 14 to the center sill of the car. The main portion 15 of the bracket which extends transversely of the car and which is spaced above the extensions 13 may be conveniently connected to the latter by substantially upright legs 18. As will be obvious the upper surfaces of the portion 15 of the bracket and the portions 69 of the corner posts are disposed in the same plane so that when the door is in closed position it rests upon and is supported by each of these portions.

Although the walls 88 of the trunnion housings prevent substantial inward movement of the lower portion of the door adjacent the sides thereof it is desirable to provide means for preventing inward movement of the lower central portion of the door when the door is in closed position. It will be appreciated that the tendency for the lower central portion of the door to move inwardly is occasioned by severe draft and bufilng shocks to which the car is subjected. The means employed in the present instance for preventing this inward movement of the door comprises a member Tl secured to the bracket 12 slightly inwardly of the door. This member is of angleshape and has one leg 18 secured to the portion I5 of the bracket by rivets l9 and another leg 88 which extends upwardly adjacent the inner edge of the bulb portion of the reinforcing member 51. Outward movement of the lower portion of the door is, of course, prevented by the upwardly projecting flange ll of the end sill, which overlaps the outer face of thevdoor and the adjacent portion of the corner posts.

When the door is moved inwardly to open position it pivots or rotates about its trunnions 65 until the inwardly projecting flange 58 of the lower reinforcing member 51 contacts with the floor of the car. From this position until it assumes fully open position the door rotates about the free edge of the inwardly projecting flange 58 as a center causing the lower edge of the door and the trunnions thereof to move upwardly. The position the door occupies when in open posltion and the extent to which the trunnions have moved upwardly in their housings is fully shown in Figure 15. As shown in dotted lines in Figure 9 a portion of the outer edge of the flange 58 of the lower reinforcing member engages the bracket I2 when the door is in open position. Since it may be necessary to remove the door from the car for purposes of repair and replacement the upper ends of the trunnion housings are open so that the door may be readily lifted bodily from the car.

Secured to each of the upper corners of the door is a bracket 9i preferably of cast metal. This bracket has a plurality of plate-like portions 92 and 93, respectively, the former overlapping the outer face of the flange 54 of the door reinforcing member 53 and being secured thereto and to the top flange 52 of the door by rivets 04. The other plate portion 03 of the bracket is interposed between the door and the adjacent side wall of the car, being overlappingly secured to the adjacent side marginal flange 5| of the door by rivets 85. These plate portions of the bracket are preferably integrally connected by an additional plate portion 06 which overlaps the outer face of the door. In order that the plate portion 9 may contact with the inner face of the adjacent portion of the flange of the corner post the inturned rib 43, which is of a depth equal to the thickness of the plate portion 86, terminates below the bracket 02. Projecting outwardly from the portion 89 of the bracket is an upwardly extending lug 81 adapted to cooperate with means movably mounted on the side wall of the car for maintaining the door in closed position. The lug 91 may be conveniently reinforced by a rearwardly extending rib 08. The means cooperable with the lug comprises a latch or book member 09 revoluhly mounted on a boss integrally formed with and projecting inwardly from the upper portion of the stem of the corner post. This boss is apertured and receives one of the rivets 9i employed for connecting the corner post and vertical flange of the top rail, and to prevent axial movement of the latch with respect to the boss a washer 9| may be interposed between the latter and the adjacent head of the rivet. This mechanism for maintaining the door in upright or closed position is of the type described and claimed in application Serial No. 413,050 filed jointly by Fred A. Isaacson and myself on December 10, 1929,, and, like the latch shown therein, latch 99 is provided with ledges or shoulders 92 and 93 for respectively cooperating with lug 81 to maintain the door in partially closed and fully closed position, the ledges in the present mechanism, however, being spaced a greater distance apart for a purpose which will hereinafter appear.

The portion of the flange of the corner post adjacent the latch is apertured or cut away as at 94 to permit the free end of the latch to extend therethrough. The aperture is of such size that the portion of the'corner post defining the lower portion thereof will support the latch in position to be engaged by the lug 81 when the door is moved from open to closed position. To maintain the latch in operative engagement with the door a cam 95 may be conveniently employed and it is preferably pivotally mounted upon a thimble 96, or the like, secured to the corner post by a rivet 91.

Means of a character similar to that described and claimed in said application Serial No. 413,050 is preferably provided for interlocking the side walls and each end door to prevent the sides from spreading due to lateral forces exerted by granular and other lading which may be carried in the car when the end doors are in closed position. However, as the side walls of the car often spread when the doors are in open position means is also preferably provided for drawing the sides of the car inwardly into their normal upright positions before the doors assume fully closed position. Although separate means may be employed for effecting these two results, namely, that of drawing the side walls inwardly and that of interlocking the side walls and door when the latter is in closed position it is preferred to employ one means for both purposes. In the present embodiment of the invention this means comprises lugs or

members

98 and 99 respectively integrally formed with the corner post 2I and door bracket 9|. The member 98 extends downwardly from the portion 49 of the corner post and inwardly from the adjacent portion of the flange thereof while the member 99 extends upwardly from the plate portion 02 of the bracket BI adjacent the corner of the door. At its inner end the member 99 may be reinforced by ribs or flanges I00. It will be appreciated that these members constitute one of the two pairs employed at each end of the car.

Each member of each pair is fashioned with a plurality of offset surfaces IOI and I02 extending substantially parallel to the path of movement of the door and connected by a beveled or inclined surface I03. Each member is further provided with an additional beveled or inclined surface I04 leading to the adjacent surface IOI. The manner in which these various surfaces of the members cooperate as the door is moved toward closed position is clearly illustrated in Figures 16, 17, and 18. Thus, when the door is moved toward closed position, the inclined surfaces I04 contact as illustrated in Figure 16, provided the sides have spread a relatively great amount. Since these surfaces extend obliquely with respect to the path of movement of the door closing movement of the door will draw the side walls inwardly and permit the door to assume the full-line position indicated in Figure 17. In this position it will be perceived that the surfaces IOI of the members are in engagement thereby interlocking the door and side walls and consequently preventing the latter from spreading outwardly into the position shown in Figure 16. It will, of course, be obvious that should the side walls not have spread the amount indicated in Figure 16 but only to the amount indicated in Figure 17 the door will immediately assume the position indicated in Figure 17 without surfaces I04 being brought into engagement. As the inclined surfaces I03 and I04 of the door member are respectively in engagement with the surfaces I04 and I03 of the corner post member continued closing movement of the door will cause the inclined surfaces of the door member to slide along the corresponding surfaces of the corner post member'thereby further drawing the sides inwardly and permitting the door to assume the position indicated in Figure 18. In this last-named position it will be seen that the offset surfaces IN and I02 of the door member are respectively in engagement with the offset surfaces I02 and IN of the corner post member so that the side walls and door are in interlocking relation.

As considerable difficulty may be encountered in drawing the side walls inwardly by closing movement of the door, means may be conveniently provided whereby a removable pry lever may be employed. In the present form of the invention the upper portion of the stem of the comer post may be formed with a plurality of apertures I05 and I06, respectively, affording a plurality of fulcrum points for a removable lever It". When the door is in the position indicated in Figure 16 the removable lever may be inserted in aperture I05 and caused to bear against the adjacent side marginal flange of the door. By moving the lever toward the door these two parts and the corner post will assume the position indicated in dotted lines in Figure 16. Thereafter the lever may be brought into cooperation with the aperture I06 and the door in the manner illustrated in full lines in Figure 1'7 and by suitably operating the lever, it, and the door and comer post, will assume the dotted line positions indicated in Figure 17. In order that the door may not be accidentally displaced from the position indicated in full lines in Figure 1'! the ledge 92 of the latch is so arranged that it will operatively engage the lug 81 of the door to maintain the door in that position. The other ledge 93 of the latch is, of course, intended to engage the lug to maintain the door in the fully closed position indicated in Figure 18. By providing the means disclosed for drawing the side walls inwardly the removable lever may be employed to simultaneously effect this result and to move the door toward closed position.

From the forgeoing it will be perceived that rugged and simple means is provided for strengthening the ends of drop end door gondola cars, for maintaining the door in closed position, for drawing the side walls of the car inwardly and for interlocking the side walls with the door when the latter is in closed position.
