Figure 5 is'a fractional sectional view of a portion of the car showing the parts 11 illustrated in Figure 4, with the door in .partially open position, and thedoor lifting'arm of the mechanism in engagement with the door.

As shown in the drawings, AA denotes 1v the side walls :of theca-r; B-B the sloping end walls of "the car; C the longitudinalcenter sill; D the transverse cross-tying structure; EE hopper-structures on the opposite sides ofthe-center sill; F-F transversely eX- tending hopper end walls; 1G door operating mechanism for the center doors;zH door operating mechanism for the side doors; J the l Wheels of the car; which the car rests.

Each side wall A of the car includes side sheeting 10, side'stakes 11and l2, and upper and lower reinforcing marginal members, as indicated-at 13 and 14, respectively. Each sloping end wall B, includes sloping end sheeting 15 flanged upwardly, as indicated at 1.6, for attachment .to the car side walls. The

and KK 'therails on center sill C includes two channel members cludes a channel-shaped member 21 extending transversely from side to side of the car and is connected at each end with the car side by side gussets 22. On each side of the member 21 are ridge plates 23 each formed with an inclined shedding portion 123 and a vertically depending wall portion 24, the latter being made to conform to the shape of the hopper, said vertical wall portions 24 be- 111g spaced apart from each other an appreciable distance and braced by brackets 25.

Each hopper structure E, at opposite sides of the car, includes a lower if-shaped section having inner and outer discharge openings, respectively adapted to be closed by a continuous inner door 26 and a continuous outer door 27. Above the doors, each hopper on the inner side thereof is defined longitudinally by the ridge above the center sill structure C, and on the outer side by a sloping floor 28, which slopes downwardly from its adjacent side wall A. The lower margin of each said sheet 28 is spaced upwardly an appreciable distance from the associated outer door and reinforced by an angular-shaped member 29 furnishing a lip or margin. Said inner and outer doors are hinged on a common pivot center disposed below the inverted apex of the \f-shaped hopper, and which preferably consists of a longitudinally extending shaft member 30, supported in brackets 31 and 131, respectively disposed at the ends of the hopper and at the central cross-tying structure D, the doors being suitably cut away, as indicated at 32, to clear said brackets. The inner doors 26 are flanged at 33 concentrically with respect to the center of the shaft 30, and the rear edges of the outer doors are tangent to said concentric flange 33. The doors 26 and 27 are rigidiiied longitudinally by beam members 34 and 35, respectively disposed adjacent the hinge and free edges of the doors, and said doors are further braced transversely by a series of braces, as indicated at 36 and 37. The outer marginal edge of each inner door is deflected to present, as t 38, a suitable rigidifying means or flange for the edge of the door, said flange when the door is in closed position being adapted to abut against the inwardly directed marginal flange 120 of the center sill structure. The doors 26 and 27 are respectively mounted on the shaft by means of hinge brack ets 39 and 40. The hinges 40 on the outer doors 27 are formed of a. plurality of walls 4141 spaced apart from each other a suflicient distance to straddle hinge 39 on the inner door, the latter being preferably formed of a single wall 42 of appreciable thickness. The doors 26 and 27 are each preferably adapted to extend continuously from end to end of the hopper and beneath the transverse central rigidifying structure D. At each end of the base of the hopper there is disposed the transverse end hopper wall F, which in- 1y" triangular cludes a vertical end wall plate 43, said wall adjacent the inner door 26 of the hopper being shaped to conform to the contour of the hopper, and adjacent the outer door said plate is extended beyond the outer edge of the outer door 27, as indicated at 44 in Figure 4 for the purpose of presenting a baffle plate adapted to prevent overflow of ballast at the end of the said outer door when the latter is in open position. Each inner door 26 is longitudinally extended at its opposite ends beyond the end Walls F of the hopper structure the projected portions increasing in extent from the hinge to the free edge of the door, thus providing a door extension, indicated at 450, projecting beyond the end wall F at each end of the door of substantialshape. At the outer margin of each excension 450 there is formed an upwardly disposed baffle plate 45 which lies at an angle to the related hopper end wall F and outwardly of the same, thus providing increased length for the door, with the minimum length. adjacent the hinged axis of the door, and diverging to provide the maximum length along the free edge thereof.

The pair of inner doors 26 are raised and lowered in unison by means of the door operating mechanism G, which includes, for each of the inner doors 26, a longitudinally extending drawbar 46 preferably formed of inverted U-shape, having connected thereto a series of flexible connections 47, such as chains, which extend over pulley wheels 48 and are secured at their free ends to the door 26. The pulley wheels 48 are mounted on pivot pins 49 which extend through brackets 50 and the center sill webs. The bars 46 on the respective sides of the center sill are moved in unison by means of a rotary shaft 51 which extends through the center sills and is pivotally mounted therein in bearings 52, said shaft projecting toward one side of the car to permit operation thereof. Self-locking winding linkage mechanism, as indicated at 53, connects each of the bars 46 with the said shaft 51.- The mechanism 53 includes square hubs 54 on the shaft 51, around which wind links 55, 56, 57, 58 and 158, the latter being the terminal link member, and formed of hook shape whereby a straight line passing through the pivots at the respective ends of said terminal link member 158 will pass slightly beyond the center of the shaft 51, and lie on the far side of the axis of rotation of said shaft, when the mechanism is in locked position, thus rendering the mechanism selflocking. The shaft 51 is actuated fromthe side of the car by means of a worm wheel 59 (Figures 1 and 3) and gear 60 carried at the lower part of the car side and preferably enclosed in a housing 61, said worm and gear being disposed out of the path of movement of the outer doors. The worm wheel 59 is preferably actuated by a short longitudinally and lading acting on the same,

extending'shaft 62, said shaftbeing preferably provided with suitable ratchet and lever mechanism for rotating the same, as inclicated conventionally at 63.

The operation of the mechanism controlling the inner doors 26 is as follows Assuming the doors to be in closed position, as indicated at the right in Figure 4, and the mechanism G positioned as in Figure 2, the operator, through the medium of shaft '62 and the worm and gear mechanism, rotates shaft 51 in a counter-clockwise direction, as viewed in Figure 2. As the shaft is rotated inanimwinding direction, the drawbar 46 is moved longitudinally, due to the weight of the, doors through the flexible connections 47. The unwinding action of the mechanism is continued until such time as the mechanism is fully released, when the inner doors will be in position, as indicated by dotted lines in Figure 4. The raising of the doors is a reversal of the door lowering operations, being accomplished by rotating the shafttl in a clockwise direction until the hooked link 158 assumes its locked position with reference to the shaft 51, which, of course, holds the doors 26 closed.

Each of the outer doors 27 is adapted to be operated independently of the other outer door and of both inner doors 26. The operation of each of'said doors is through the medium of the in cchanism H. Each of the mechanisms H includes flexible connections, such as chains 64, adapted to wind on sheaves carried on a longitudinally eXtending shaft 66, said shaft 66 being mounted adjacent and above the free edge of the related door and supported. at the cross-tying structure in a bearing 67 carried by bracket 68 and supported at its ends by bearing members mounted on the baffle plates 44. There are preferably three flexible connections 64 to each door, each of said connections being connected .to the associated sheave 65 and to the bracket member 71 on the .door, :said member 71 being secured to the beam member 35 and extended beneath and rearwardly thereof, asindicated at 72. The extension 72 is adapted to receive the threaded end-73 of the flexible connection 64, whereby the length-of the connection may be'adjusted. Adjacent the'free edge of the door, the bracket 71 is provided with members having load bearing surfaces 74 inclined with reference to the main plane of the door. Said bearing members 7 4 are disposed on opposite sides of the flexible connection, and in alignment with lugs 7 5 5, which are fixed relatively to, and-disposed on either side of each sheave 65' and constitute extensions thereof. \Vith the doors in closed position, the lugs 75-75., which are of armate form, engage beneath the oblique load bearing surfaces 7 4 on the door in such :a man.-

ner that the outward thrust of the door under theloadsuppo-rted thereby is directed toward the axis of the'operating shaft 66, thus eliminating any tendency for the shaft to rotate or twist when the doors are in closed position.

t each of the flexible connections 64, the V door 27 is coped, as indicated at 77, for the connection to extend therein, and a sealing bracket 7 8 is disposed on the lower edge of the sloping floor 28,'in alignment with'the said cope, for the purpose of sealing said opening when the door is in closed position.

The operation of the mechanism H, assuming a door 27 to be in the openposition, as shown on the left hand half of Figure 4,- is as follows: To close the door, the shaft 66 is rotated in a counter-clockwise direction and the connection 64 winds on the sheave '65 until such time asthe laterally projecting lugs 75 come in contact with the bearing surfaces Y4 on the door, at which time the flexible connections 64 are then relieved of the weight of the door, and continuedrotation, ofthe shaft in the indicated direction causes the lever arms, as presented by the sheave lugs 75, to lift the door above the level of the shaft,

and arcuate surfaces of the lugs 7 5 wedge be-' neath the door, locking the same in tightly closed position. This arrangement provides for a self-locking mechanism, and also for lifting of the door above the level of the shaft in a simple manner,'and. thus renders unnecessary large and cumbersome brackets on the underside of the door such as would be liable to distortion by coming in contact with the unloaded ballast. The operation of each longitudinal shaft 66 is effected from the side of the car by a short transverse shaft 79, said shaft being operatively connected by means of worm and gearing enclosed in a housing and indicated conventionally at 80.

The arrangement of worm and gearing for the inner and outer d'oors, permits of the gradual opening of the doors whereby they may be maintained in any adjusted position and the flow of ballast controlled and limited to theexact quantities desired. The mounting of the doors and the proportioning of the doors in relation to the rails K eliminate the tendency to flood thetrails during the unloading of ballast, as the disposition of the adjacent hoppers to each other and to the rails I standard ratio for ballast.

In order to ensure against flooding of the rails, during ballasting, it is essential that excessive flow of ballast at the ends of the doors should be guarded against, and to this end the baflle plates 44 are disposed on the car structure at the ends of the outer doors 27, and a novel construction is employed for the center or inner doors 26 which provides for lengthening the doors beyond the end walls F of the hopper, whereby the material which would normally flow from the ends of the hopper is diverted and placed beyond the free edge of the doors. The extension 450 on each inner door which thus projects be yond the end wall of the hopper, is of triangular formation, diverging outwardly from the hinge edge of the door towards the free edge thereof, whereby the door increases in length as the free edge is approached, thus providing a door having a greater length at its free edge than at the pivotal end thereof. At each end of each door the u wardl extendin P y a baffle plate 45 is preferably formed by flanging the door upwardly, said baflle lying at an angle to the end hopper wall, and formed to diverge outwardly from the hinge end theroof and also formed with its greatest depth adjacent the free edge of the door, thus providing for maximum interception of ballast at the point of greatest door opening. This arrangement, by diverting the end flow of material from over the end of the door to the outer edge thereof, increases the length of the dumping platform, thereby allowing the ballast to spread out, and insures a more even flow of the discharging material. The diverging construction of the door also enables the door in any of its positions to clear the wheels J and the spacing of tne bafile plate 45 outwardly from the hopper wall permits adequate clearance beneath the sloping hopper end wall B for the reception of a baffle plate of extended depth when the door is in closed position.
