terial of greater length than the car or in a substantially upright position to permit of loading of granular material or other lading l of less length than the car. When the end doors overlap the door of the car they are considered as being in open osition and lwhen they are disposed substantially upright they are considered as being in closed position.

The principal object ofthe 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 withthe car. A further object of the invention is to provide means for drawing the side walls of the car inwardly preparatory to the doors assuming closed position.

A still further ob] to provide an improved corner post particularly applicable to this type of car.

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

A primary feature of the invention consists in integrally forming the corner post of the car with 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 projecting beyond the side edges thereof for cooperating 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 ect of the invention isv .car with corner posts having p ortions'rig` I idly secured to the horizontal and vertical legs of the adjacent side top rails. 1

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

A still furtller'featurel of the invention consists in providing the car with a pluralityof 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 '65 adapted to draw the side walls inwardly.

Other and more specific features of the in-` vention residing in advantageous forms,

combinations and relations of pairs will hereinafter appear 'and 'be pointed out in 70 the claims.

Figures 10, 11 and 12 are enlarged sectional m0 construction of the car adjacent only one corner thereof itis to be understood that the construction is duplicated at each corner and that the mechanism illustrated for maintaining the door in closed position in-only one of the two employed for each door.

Referring vmore particularly to the drawings 1 indicates one of the side walls of the car which in the present embodiment of the invention consists of a plurality of wooden boards or lanks. Interposed between the top board an the top side rail 2 is a longitudif nall extendin metal late 3 which is descri ed in detail in my atent No. 1,698,865, January 15, 1929. Although the rside top. rail may be of any desired or convenientshape I prefer to use a bulb anglehaving a substantially -horizontal vflange 4 'and a substantially vertical flange -5, the latter beinv rigidly secured to the longitudinally extending plate 3 in overlapping relation to its inner face.

Secured tothe bottom plank or board of the car siding is a longitudinally extending angle-shaped member having a vertical flange 6 preferably overlapping the outer face of the siding, being secure thereto by bolts7, and a horizontal flange 8 which extends inwardly and underlies the floor 9 of the car which is also of wood. Extending beneath this angle- .shaped member is'a channel member 10 having a substantially vertical web 11 and upper and lower inwardly projecting flanges 12 and 13, res ectively, the `former being rigidly Y secure to the flange 7 of the angle member.

Thus, each side sill of the vcar is formed of two parts, namely, the angle-shaped member and the channel-shaped member. The former, however, terminates inwardly of the end wall of the car, to vbe hereinafter described, while the latter projects therebeyond.

As is usual the wooden floor 9 rests upon the top cover plate 14 of the center sill which,l in addition to this late, 'isformed by the spaced longitudinal y extending beams 15. The center sill like the channel-shaped member of the side sill projects beyond the end walls of the car. The center sill and side sill are connected -by an end sill 16 preferably ofv angle-shape having an upwardly projecting substantially-vertical flange 17 and an outwardly projecting substantially horizontal flange 18. This last-named flange rests upon rivets 20.

ortion 24, the

eing secured thereto by a pluralit of bolts 25. This portion of the stem of t e corner post also overla s the outer faces of the vertical flan e 6 of the angle member and the web 11 o the channel, being secured to these parts by

rivets

26 and 27, respectively. The upper portion 23 of the stem overlaps the inner faces of the metal plate 3 and of the depending or vertical flange 5 of the side top rail. To properly space the plate 3 from the adjacent .portion of the stem 23 the latter is integrally formed with a pluralityof outwardly projectingv bosses 28 which abut the inner face of the plate and each is provided with an aperture for receiving rivets 29 for rigidly connecting the Aassociated parts.

voo

Furthermore, the portion of the stem 23 irnmediately yadjacent the flange 5 of the top ginal edge is preferably provided with an inwardly projecting rigidifying bead or rib 34. Where this rib approaches the horizontal flange of the top rail it decreases in width as 'at 35 to form a flange 36 which is disposed beyond the outer edge of the adjacent portion of the top rail. At its lower portion the outwardly projecting portion 33 decreases in width to adjacent the lower end of the corner ost'.

p The inwardly projecting ortion 32 of the flange of the corner post is a apted to overlap the outer face of the drop end door 37 and forms means for limiting outward movement of the door. To rigidify this portion of the flange it may be advantageously integrally connected tothe stem .by a plurality of substantially triangularlyshaped ribs or flanges 38, As the wooden siding extends'to substantially'grrthe portion 32 of the corner post, .the boards lconstituting the sidin are gained out oilg'cut away to ermit the anges 38 to extend therebeyon Above the wooden siding the inwardly projecting portion 32 of the ing portion 32 of .the flange of the corner post thereof 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 ange 40 overlappingly secured to the inner face of the wooden siding by the bolts 25 and with a leg or flange' 41 overlappingly secured by rivets 42 tothe inner face of the flan e portion 32 of the corner post. Thus the anges 41 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 41 of the angle members. 39 and is preferably integrally formed with an inturned rigidifyingrib or -fiange43 which terminates substantiallyfin the plane of the inner faces of the flanges i 41 and thereby also is adapted to contact with 'the outer face of the door.

As shown in Figures 10 and' `11 the flanges 38 and 38a are formed with extensions 44 for integrally conj necting the inturned kange-43 therewith.

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 17 of the end sill, being rigidly secured thereto by a plurality of rivets 46. Where the flange 17 of the end sill overlaps the corner post it is offset outwardly as at 17a. 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 47 which overlaps the upper face of the horizontal flange or leg 4 of the side top rail, being 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 49 and' in order to reinforce the

portions

47 and 49 they may be formed with a plurality of upwardly extending ribs 50. From the foregoing it will be readily apparent that a corner post constructed in accordance with the foregoing description will, when applied tothe car in the manner described, adequately and efficiently reinforce and rigidify the end portions of the lsid'e walls of the car.

While the drop end door 37 may be made of any desired material it is preferably fashioned from sheet metal, being integrally formed along its sides and top with inwardly projecting

marginal flanges

51 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 ange 52 of thedoor and a flange 56 disposed in a plane substantially parellel with that of the door. This 'top reinforcing member and the side marginalflanges 51 extend equal distances beyond the plane of the door` so that they may engage the floor of the car when the door is in open position to tal plane. The lower portion of the door is also provided with a reinforcing member 57 which may advantageously be a bulb angle. One flange or leg 58 of this angle extends inwardly from the door for the same distance support the latter in a substantially horizon 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-na'med flange preferably extends beyond the bottom edge of the door and is enlarged to form the bulb 61. Thevinwardly projecting flange 58 may advantageously be rigidly connected toadj aent portions lof the side flanges 51 by angle brackets 62. 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 fiange 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 forces -occasioned by material resting thereon will not tend to warp and distort it.

For movably associating the end door with the car the -lower reinforcingy member 57 is rigidly provided with means projecting beyond opposite side edges of the door. In the present embodiment ofthe invention this means is formed integral with the reinforcing member and comprises the bulb 'portion 61 which constitute trunnions 65.` Although any extend'. The wall 66 and the adjacent portion of the flange 32 are preferably integrally connected b a portion 67v which extends parallel with an 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 67 may advantageously be integrally connected to the stem of the corner post by a substantially horizontal portion 68.

To support the door at its lower edge when' 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'projectin portion 32 of the flange of the corner post an the wall 66, connecting the latter and the wall 67 to the flange. The horizontal portion 69 is preferably provided with downwardly

projectin g extensions

70 and 71, the latter constituting a continuation of the wall 67, which terminate at the lower edge of the inwardly lprojecting 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 doorrests upon and is suported by a bracket having lateral extensions 3 secured by rivets 74 to the center sill of the car. ,The main portion 7 5 of the bracket which extends transversely of the car and which is s aced above the extensions .73 may be conveniently connected to the latter by substantially upright legs 76. As will be obvioiis the upper surfaces of the portion 75 of the bracket and the portions 69 of the corner posts are disposed in the saine plane so that when the door is in closed position it rests upon and is supported by these portions.

Although the walls 66 of the corner post prevent substantial inward movement of the lower portion of the door adjacent tlie 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 bufling shocks to which the car is subjected. The means Y employed in the present instance for preventing this inward movement of the door comprises a member 77 secured to the bracket 73 This member is of angle-shape and has one leg 78 secured to the portion 7 of the bracket by rivets 79 and another leg 80 which extends upwardly adjacent the inner edgeof the bulb portion of the reinforcing member 57. Outward movement of the lower portion of the door is, of' course,

:,ssaius 'until it assumes fully openv position the door rotates about the free edge of the inwardly projectingA 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 position and the extent to which the trunnions have moved upwardly in their housings is fully shown in Figurel. As shown in dotted lines in Figure 9 the portion of the lower reinforcing member adjacent the bracket 72 engages the latter when the ,door is in open position. Since it may be necessary to remove the door from the car for purposes ofrepair and replacement the upper ends of the itrunnion housings are open so that the door` may be readily lifted bodily from the car. ,I

. Secured to each of thel up' er corners of the door is a bracket 81 prefera ly of cast metal. This bracket has a plurality of plate-like portions 82 `and 83, res ctively, the former overlapping the outer ace of the flange 53 of the reinforcing member 52 and being secured thereto and to the top flange 52 of the door by rivets 84. The other'plate portions 83 of the bracket is interposed between the door and the adjacent side wall, being overlappingly secured to the adjacent side marginal flange 51 of the door by rivets 85. These plate portions of the bracket are preferably integrally connected by an additional plate portion 86 which overlaps the outer face of the door. In order that the plate portion 86 may contact with the inner faceof 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 82. Projecting outwardly from the portion 83 of the bracket is an upwardly extending lug 87 adapted to cooperate with means movably mounted on the side wall for maintaining the door in closed position. The lug 87 may be conven- Aiently reinforced by a

rearwardly extending rib

8,8. The means cooperable with the lug comprises a latch or hook member'89 revolubly mounted on a boss 90 integrally formed with and projecting inwardly from the upper portion of the stem of the corner post. This boss is apertred and receives one of the rivets 31 employed for connecting the corner post and vertical vflange of the top rail and to prevent axial movement of the latch with respect to the boss a washer 91 may be used. The construction of the latchv is substantially the same as the one illustrated'in an appliprevented by the upwardly projecting flange.

nesaaaa cation led jointly by Fred A. Isaacson and me on February 10, 1929, except that the ledges or shoulders 92 and 93 with which it is provided for cooperating with the lug 87 to' respectively maintain the door in partially closed and fully closed position, are spaced a greater distance apart for a purpose which will hereinafter appear.

The portion of the iange of the corner post adjacent the latch is apertured or out away as at 94 to permit the free end of the vlatch to extend therethrough. rIhe aperture llatch in operative engagement with the door a cam 95 may be conveniently employed, it being preferably pivotally mounted upon a thimble 96 orthe like, secured to the corner post by a rivet 97.

As the side walls of the car tend to spread.A

'25 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, means is preferably provided for interlocking the side walls and each door. Furthermore, since the side walls of the car may spread when the doors are in open position means is also provided whereby the sides of the car maybe drawninwardly into their normal upright positions. Although separate means may be employed for effecting thesev two results, namely, that of drawing -v the side walls inwardly and that of interlocking the side walls and door when the latter vis in closed position to prevent spreading of the walls lit is preferred to employ one means for both purposes. In the present embodiment ofthe invention this means comprises lugs or

members

98 and 99 respectively integrally formed with the corner post 21 and door bracket 81. The member 98 extends downwardly from the portion49 of the corner post. and inwardly from the adjacent portion of the flange thereof while the member 99 extends upwardly from the plate por-l tion '32 of the bracket 81 adjacent the corner post of the door. Atv its inner end the member 99 may be reinforced by ribs or anges 100. It will be appreciated that these members constitute one of the' two pairs employed at'each end of the car. f

Each member of each pair is fashioned with a plurality of oifset surfaces 101 andA .M2-extending substantially parallel to the path of movement of the door, which are connected bya beveled or inclined surface 103 extending obliquely ,to that path. Each member is further provided with an additional oblique surface 104 leading to the adjacent surface 101. The manner in which these various surfaces of the members co-Y operate as the door is moved' toward. closed 17 and 18.` Thus, vwhen the dooris movedv towardclosed position, the inclined surfaces 104 Contact as illustrated yin Figure 16, provided .ihe 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 101 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 amountindica'ted in Figure y16 but only to the amount indicated in-Figure-17 the door will immediately assume the position indicated in Figure 17 without surfaces 104 being brought into engagement. As the

inclined surfaces

103 and 104 of the door member are respectively in engagement with the

surfaces

104 and 103 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 andpermtting the door to assume the position indicated in Figure 18.l tion it will be seen that the offset

surfaces

101 and 102 of ther door member are respectively in engagement with the oEset surfaces In this last-named posi- 102 and 101 of the corner post member so that the side walls and d'oor are in interlocking relation.

As considerable difficulty may be encountered in drawing the side walls inwardly by.

closing movement of thedoor means may be conveniently provided whereby a removable pry lever may be employed. In the present moving the lever toward the door these two parts and the cornerpost will assume the position indicated in dotted lines in Figure 16. Thereafter the lever may be brought into cooperation with the aperture '106 and the door in the manner illustrated inv full lines in Fi re 17 and by suitably operating the lever, it, and the door and corner post,

will assume the dotted'line positions indicated in Figure v17. In order that the` door may not .be accidentally displaced from thel position indicated in full lines in Figurej 17 From the foregoing it will be perceived.

that rugged and simple means is rovided for strengthening the ends of the rop end door gondola car, for maintaining the door in closed position, for drawing the' side walls inwardly and for. interlocking the side walls with the door.-
