Referring first to the construction illusvo tre't'ed in Figs. 1 to 7 inclusive, wherein my improvements are shown as applied to a air of the soca;lled W-hopp'er type having a door hinged adjacent its upper portion and mounted for vertical swinging movement; We

In said drawings, 11G) denotes one of" the side walls of the car, 11 the lower ehord of the car side, 12 one of the beam sections'employed to make up the girder center sill of well known form. The center sill strueture eo is built up by the enip-13oyment of two of these center sill sections" united by s top cover piste 1'3 and heaving a SlH'IIlOllIltl-llg' ridge M of A- sliepe. As customary in the W-type 0-1! ear,

a. transversely extending ridge is formed by so theridge sheet 135 which constitutes the upper wall of a hopper, it being understood there are a plurality of hoppers in the car, two on each sideof the center sill and arranged in pairs transversely of the ear. Inasmuch as the construction is'the same for each" hopper, the deseription herein will be confined to only one of such hoppers.

Each of saitl hoppersis defined by a lon-gitnd in-a-l-ly sloping hopper sheet 16, 22 vertical inner side hopper sheet E7,- and an outside hopper sheet l8, the latter'slopin inwarfly towarosthe longidsndinal eenter ineof the car and: having its margin 19 hent outwardly as shown, and then substantially in the: gem' eral direction of the main plate as indicated at 20, to present a Z-shape section, said bend 19 providing an abutment for the door. The inner side hopper sheet 17 is secured to the side of the center sill and deflected at an angle beyond the outstanding marginal flange 112 of the center sill and thence downwardly to provide a substantially vertical depending portion 21 having its margin formed with an inwardly directed sloping portion 22, said portion 22 being flanged outwardly at 23, and thence in the general direction of the plate, as at 24. The portion 23 thus provides an abutment for the door, and the portion 24 a shoulder adjacent the abutment.

The outer edge of the bottom sloping hopper 16 is rigidified by amember A which is preferably formed of cast metal and includes a main portion extending along the edge of the sheet as indicated at 25, Fig. 7, and an upwardly extending portion at each end indicated at 26 and 27 respectively. These upw'ardly extending portions overlie the inner and outer hopper sheets respectively and are secured thereto. The member A is preferably formed with an outstanding portion 28 of heavier section than the main portion and constitutes an abutment for the door, said abutment being in substantially the same line as and forming a continuation of the abutments on the respective inner and outer side hopper sheets, thus forming a substantially continuous abutting surface for the three unsuppdrted door edges. The member A ad acent the abutment 28 is formed with a heavy depending portion of bulb-like formation 29, forming a shoulder adjacent to the ledge 28. The member A adjacent the body portion is formed with an inte ral depending flange 30 disposed snbstantialfy normal to the plane of the sloping floor and acting as a reinforcement for the same.

Adjacent the edge of the upper sloping floor formed by the ridge sheets, the sheet is reinforced by a member B preferably formed of cast metal with angularly related flanges, one of said flan es 31 being secured to the sheet and the ot er of said flanges 32 outstanding therefrom. The member B is provided with a wall portion 33 at its inner end, which is attached to the center sill, and at its outer end said member is provided with an integral flange portion 34 disposed in overlying relation to the outer side hopper sheet 18. The outer hopper sheet 18 is rigidified by an additional plate member C which extends contiguously with the marginal abutment 19 of the plate. and is sandwiched between the hopper sheet and the respective overlying flanges 27 and 34 of said members A and B. Outstanding from the depending flange 32 of the member B are two hinge lugs 35 each adapted to receive a hinge pin 36 whereby a discharge door D is pivotally mounted in position.

The discharge door D preferably formed of cast metal with outwardly extending flanges at its margin, so as to provide a top horizontally extending flange 37 preferably of arcuate formation, inner and outer side flanges 38, and a lower flange 39 adjacent the free edge of the door, said res ' ective lflanges 37, 38 and 39 co-operating to orm a continuous reinforcement around the edge of the door. and integrally uniting said inner and' outer side flanges 38, are a pair of depending reinforcing flanges 40 and 41 respectively disposed adjacent the hinge edge of the door and the outer edge thereof, but spaced an appreciable distance from said edges.

Integrally connecting said respective flanges 40 and 41 are a plurality of integral flanges indicated at 42, 43, and 44. Substantially in alignment with the central rib-43 are ribs 45 adapted to continue the plane of the rib 43 to the respective inner and outer edges of the door. The door D is pivotally mounted by integral lugs 46 to the respective hinge bracket portions 35. Extending between the outer flange 39 and the flange 41 are a plurality of pairs of integrally formed spaced lugs 47 adapted to co-operate with a portion of the latching mechanism in a manner as will be fully pointed out here-. inafter. The door latching mechanism broadly includes a bodily movable shaft 48 loosely mounted to have bodily movement along the outer face of the door, and spaced apprecia bly from the main body of the door to clear the side flanges and other integral door bracing. The inner and outer side flan es 38am provided with transversely widened portions 49 and 50 respectively, which extend throughout the extent of movement of the shaftand constitute abutment runways for the shaft. The shaft 48 projects beyond the respective ends of the doors and beyond the inner and outer side walls 17 and 18 and cooperates with inner and outer shouldered brackets F and G, respectively mounted on the inner and outer hopper sheets.

Rigidly mounted on the shaft and inalignment with spaced lugs 47 on the door are "hub. members 51, each including a sleeveportion 52 rigidly united with the shaft by means of rivets 53. Each hub member 51 includes a pair of spaced arms 54 disposed in alignment with the lugs 47 on the door, the space be. tween said arms 54 being substantially equal to that between the pair of lugs 47, and" interposed between said arms 54 on the hub and lugs 47 on the door is a link member 55. The link is pivoted at one end to the: hub by a pivot 56 disposed at an appreciable distance from the axis of the shaft, and the opposite end of the link is pivoted between the lugs 47'and by a pivot 57.

Disposed outwardly of the shaft adjacent Extending across the door, bet-ween 'the'respeciive edges of the door are strep members 58 and 59, which form guides to prevent outward movement of theshaft, and

depending flange 41 by a. rivet 60. Adjacent the upper limit of travel of the shaft said guide is bent inwardly to present a wall portion 61 riveted art 62 to the outer fame of the door plate. The outer guide member" 59 is attached to the rib 4:1 in a similar manner and is extended upwardly beyond the limit of movement of the shaft and fastened to the main body of the door by a rivet 63, guide 59 is spaced from the door by a boss 64 formed integrally with the door and outstanding therefrom, said boss member having a portion adapted to present asup-porting pivot for a swingingly mounted cam 66: cam

adapted to be swung in the path of movement of the shaft to retain the latter in latching position.

Reerwardily of the cam, the boss 64 is formed with a. portion 67 of enlarged diaimeter adapted to present a wall 68 adapted to limit inward movement of said cam. The boss 64 being inthe path of the rib 42 is virtually an enlargement of the latter. l he cam 66 is formed with a projecting lug portion 69 constituting a pry-oiiportion, and on the opposite side thereof is formed with a stop lug 70 adapted to contact with the side flange of the door to limit the throw of the com.

The shaft 48 is preferably formed adjacent its outer end with a yoke comprising a pair of spaced jaws 71 adapted to receive therebetween a suitable'bar or ope-rating tool for the purpose of actuating the shaft by rotation thereof. 7

The shouldered brackets F and G- which engage with the projecting portions of the shaft are disposed in overlying relation with the respective upturned portions 26 and 27 of the lower marginal reinforcing and sealing member A, and also extended upwardly above the same to permit attachment to the side hopper sheets independently of the memher A. Each of said brackets includes a main locking shoulder 72,16 and 7', with which the projecting portionof the shuit is adapted to co-operate when in; its normal locking position, it being understood that the shaft is so disposed on the: door as to gravitate to its normal locking position due tonits own weight. Inorder to lift said shaft a suflicient distance to allow the same to drop into engaging position behind the shoulders T2,

each bracket is provided with inclined portious 13 which constitute a bevelled approach to said shoulders, said bevelled portions lieiaag adapted toengage beneath and li it the shaft as the dmr is slammed towardsclosed position.

The relation of the shaft and associated pivotal points between the shaft and the link and between the link 55 with the door is such as to provide for rolling movement of the shat-t along the faces of the outer abutment walls during; initial displacement of the shaft from its normally latched position, thus providing for ready upward displacement of the shaft as it engages with the beveled portionsof the brackets. With the latching device in the normally latched position, the intermediate portion of the link 55 rests against the shaft acting to limit further turning movement of the shaft. said intermediate portion of the link being concaved as indicated at 155 to accommodate the shaft. It will be noted that as the shaft moves downwardly towards the final locked position the axis of the shaft gradually approaches a center line passing through the respective pivots 56 and 57, thereby efieeting e'toggle leverage for foreing'the shaft to final H latched position. However, due to the fact that the axis of the shaft is not permitted to pass said center line to complete a toggle with respect to pivots 56 and 5 the shaft is in a position which admits of ready displacement when a lifting" force is exerted thereon.

The outer shouldered bracket G is provided with en'auxizlisry shoulder 74, Fig. 6, disposed slightly beyond the main shoulder T2 and connected'therewith by aninclined in wall 75, said shoulder 74 being of a, character to engage the shaft and hold the door in a nearly closed position as the door is urged towards closed position, as shown in Fig. 4. It will be appreciated that in swinging the door towards closing position the operator would normally apply force at a point adjacent the outer edge corner of the door with the result that the inner edge of the door will log due tothe fact that the unsupported weight of the door at the end remote from the point of application of the force causes the door to spring slightly. Hence, in order to provide for this condition, the inner shouldered bracket F if formed with an inclined well section 76 connecting the bevelled approach and the main shoulder, whereby the shaft may count with said inclined wall section as indicated by dotted lines at 77 in Fig. 7, and hence, when;

the shaft is rotated iii a closing direction, it will cause a lifting movement to be exerted on the door to raise the inner legging end of the door towards closed position. The outer end of the door in the meanwhile is retained in its: nearly closed position by rea son of the holding action of auxiliary ledge 74;, the relative position between the shaft and shoulders being indicated in Figs. 6

and 7, wherein the shaft is indicated in paritly closed position at 78 and fully closed at 9.

Intermediate the bracket F and the overlying wall 30 the reinforcing plate member G is formed with an outwardly flared portion 80 adapted to act as a reinforcement for the plate and also as a protection for the outwardly formed abutting portion 19 on the said well. Said plate may also be flanged at its opposite edge as indicated at 81 for re inforcement purposes. In hopper cars of this character there is a tendency for the load to pack and freeze during severe weather conditions, which fact results in the outer side plate being hammered to free the load, and it has been a common practice to incorporate a striking plate and door marginal abutment in a unitary member, a construction which renders the door and marginal abutment liable to distortion, tending to cause leakage. My improved construction decreases the liability by mounting the striking and reinforcin plate C in close proximity to but indepen ently of the door abutment and providing the outstanding flange 80 in protecting relation to said abutment.

The arrangement of the hopper construction with the side walls flanged to provide abutments for the doors and tied at the top and bottom with sturdy members extending from side to side of the hopper, in combination with the heavy flanged cast metal door, and powerfully acting wedging means to force the door in tight engagement with the hopper abutments all around the door, provide for a construction secure against leakage. In the mechanism shown in Figs. 8 and 9 my improvements are shown as applied to a door structure having upwardly turned flanges. In this construction the door has a shaft L loosely mounted thereon and having end portions projecting beyond the sides of the door for co-operation with retaining means on the car, said shaft having a pair of crank members M fixedly united therewith. Connecting the shaft and door are the two link members N, and pivotally mounted on the door to restrain movement of the shaft is a cam member P. The door proper includes a body portion 200 having upturned integral reinforcing marginal flanges indicated at 201, 202 and 203 respectively. The door on its under side is reinforced by a series of integral ribs 204, 205 and 206 extending across the door from side edge to side edge. Extending transversely of said last named ribs are other ribs 207, 208, 209, 210 and 211. Adjacent each side edge of the door there are prbvided integral portions 212 and 213 constituting runways for the shaft L, and on the outer sides of said runways are overlying wall members 214 and 215 respectively adapted to form outerguides to prevent outward movement of the shaft. A portion of the wall 214 is cut away in Fig. 8 to reveal the wall 212. Mounted between wall 215 and a boss 216 on the door is the cam member P. The integral portion 213 and wall 215 are united by a web 217 which limits movement of the cam P to the position indicated by dotted lines in Fig. 8. The upper end of each link member is extended between a pair of arms 218 formed on the crank member M and pivotally mounted therein by a pivot 219. The lower opposite end of the link is extended between a pair of walls formed by the lugs 220 integral with the door, and pivotally united to said walls by a pivot 221.

The outer end of the shaft is formed with a pair of spaced projections 222 formin a yoke to accommodate a removable operating bar therebetween. The door adjacent its upper portion is formed with a lurality of integral hinge lugs 223, where y the door is pivotally supported on the car.
