This invention dump cars. n c i i. .j An object of this invention is to Improve relates to improvements in `they construction of dump cai's having dis-vr charge openings adapted to discharge the contents of the caradjacentv the rails rwhereby ',liooding of the rails will be obviated.- f

Another object ofthe invention-is tov provide a car which will depositballast either centrally betweenk the rails or to either side thereof as desired, and `to provide meanstor positivelycontrolling the flow of the. ballast.- A more specilic object ofthe invention is' to provide. a' V-shapedv hopper construction. having a discharge door hingedadjacent the apex thereof and movable"downwardly to an `inclined position,in conjunction with means arranged to restrict thelow of the load until such time as the discharge door begins to assume adownwardly inclined position, and'to provide an increased kexpanse lolf' supporting portions movable trom underthe load to induce a ready flow of the material.:`

The invention further consists inthe improvements in the parts, and in the novel combination of the parts and Idevices herein shown, described, and claimed. c

In. the drawings orminga part'of this specification, Figure 1 is al topplan view of the hopper portion of a car-showing my improvements in connection therewith Figure 2 isa vertical sectionalfview ofthe lower portion of' the car taken on a line` corresponding substantially tothe line -2-2 of Figure 1, said View showing the centeidoors andi one or' the side doors finlopenposition.

The opposite inner downwardly and` outwardly inclined hopper sheet V'18, the hopper sheets'lSy for lach pair of transversely aligned hoppers being preferably in the forni'of a-unitary structure carriedby the center sill B, and suitably rigidi'i'ied longitudinally atthe lower margins by 'means-of angle'y members 19, said sheets 18 being also connected to the center sills 13-13 by means of brackets 20. f f

hopper section D'includes an v Each hopper s'ectioniDeis ,iilsoprovided with wall portions lateach end thereof, each wall 21 adjacent the related sloping'end C prejl'erably being yan integral portion of the slopingcnd, and being connected,therewith byja-bent portion indicated atQQ; The

flanged diaphragm 3l, secured tothe lower p'ortionof the vtransverse beam 25, and extending` from the center sill B to -the sides of A horizontally extending gusset 32 connects the lower flange of the diaphragm 3l with the center sill. Connected to the opposite sides of the diaphragm 3l are the gussets H which extend'to the vertically depending hopper end wall portions 2li, and also beneath the sloping floor portions 23, and are securely riveted to all of the said members, and also to the respective flanges 29 and 30 of the brackets 27 as before mentioned. At the eX- treme ends of the hopper sections, crossbeaiii members 132 extend outwardly from the ceir ter sill to the sides of the car, and are .each formed with a flange 33 riveted to the sloping floor portion C. The beams 132, for alimited distance at either side of cach wheel, are formed of restricted depth as indicated at 34C,

to clear the wheels under all conditions of service. Aconnecting gusset H is also disposed between each ofthe said beam niembers 132, and hopper end wall C and connected thereto, and tothe flanges 29 and BO of the adjacent bracket 27, rlhe connecting gussets H, by bracing the hopper vertical end and sloping vwalls to the transverse beams of the under-frame, and in connecting with the bi'aclretsf27, serve to rigidify the hopper construction and transmit the strain in a most effective manner from the lower portions of the hoppers to the transverse beams, and thereby to the 'center sills,and side walls of fthe car, as will be understood.

As will be especially noted by reference to Figure 2, the side doors F of the respect-ive hoppers when in closed position have their free ends spaced an appreciable distance from the apex of the hopper, and each sloping side of the V-shaped hopper is completed by the lower door G',which is disposed in substantially. alignmenttherewith. Each door G is formed to extend for an appreciable distance beneath its companion door F, when the doors are inclosed position, the free end of the dooi` G sloping ldownwardly and away from the `main plane of the door as indicatedV at 131i.

Each door G is stiifened longitudinally by *means of stiffeners as indicated at 35 and 36,

the latter preferably consistingof a Z-bar eX- tended somewhat beyondtlie ends of the door.

- spending doorG The extreme free edge of the door is rigidilied by a marginal flange 234 extending lengthwise of the door. Y i

At each side edge of the door G there is formed aV vertically extending 'wall 37 of generally triangular formation, which effects the double purpose of forming vthe said door into a pan shape and thereby restricting the flow ofinaterial over the ends of the door, and constituting brackets which arc pivotally connected with the companion door F by means of bars 38, the pivotal connection lof each bar 38 with the bracketbeing indicated at 89, and

with the door F at 4Q; The connect-ion between the respective adjacent doors F and G is preferably disposed at the ends thereof, the

door G being extended beyond the ends of the related door F, and each'bar 38 may be disposed between the end of the door F and the inner face of the wall 37 of the correposition, and each bar'SS is pivotally mounted on the door G between a bracket 4:1 and the wall 37 of the door thereby placing the pivotal connection 39 of the bar 38 in double shear.V

v Eachend of the door F is adapted to ex` tend beneath its adjacenthopper vertical end wall, which is formed in the plane ofthe said door with a laterally entendi4 gflange 42 for the purpose of providing an abuting ledge for the door to fit against when in closed position, said flange 42 beyond the free en-d of the door merging into V,the vertical end wall portion of the hopper, thereby preventing material wedg'ing between the ledge and the lower door which would interfere with complete closing` movement of said door. ment for each doorG preferably consists of a butt hinge arrangement formed of aV plurality of longitudinally'extending plates 43 formed with hinge eyes;V and'secured to each ofthe doors, the hinge portions on the door G on one side of veach V-shaped hopper being f alternated with the hinge portionson the vvother doorl G, associated with the oppositeV side of the said V-shaped hopper. ,i Y. i

The arrangemenL for raising and lowering 'the doors includes liexible elements la each of which extendsat the side edge of its related door G and isV connected to the projecting end of the Z-bar. 36. Each of-said connections is adapted to be engaged by abraclet 45, on the outer side ofthe wall 37, when the 'door is in a downwardly inclined position, thereby de-r lecting the flexible velement from the normal straight-line path from the point of its at- The hinge arrange when thedoors areinclosed s Y ysieA tachinent on the door to the point where it connected to the car structure above the door. This arrangement provides for lifting vthe door from two different points and Yaffords a differential action which gives an improved angle' of pull on the door during the initial stages'of the door raising movement, and by providing for 'an increased length of'chain t' to be taken up in lifting the door, ainechaniraeY Iii

doors are adapted tobe operatedindepend-v ently of each other, and of thecenter doors, b y means of operating shafts 47, one of which is disposed Youtwardly ofthe respective hoppers at each side of the car, the flexible' connections 44 passing overthe pulley wheels 48, mounted adjacent the hopper endV walls, and

connected to said shafts, the pulley wlieels`48 Y at the endsof the hopper sections, atthe center of the car, being mounted on shafts 49,

carried in brackets 50 and 51, the formerbeing mounted on the crossbeaml diaphragm member 3l, and the-latter depending from the l, sloping sidewalls 23. vAt the extreme outer ends of the hopper sections, each of` said pulley wheels 48 is mounted on a shaft 52 carried by brackets 53 and 54 respectively carried by thesloping walls C andthe crossbeam from tliefcorresponding crossbeam section` f132. Means yfor rotating and locking the shaftx at each end of the shaft is 'shown conc ventionally atv 61-61, this construction be-H memberl32. Secured to each ofthe respec-k tive operating shafts 46 and 47, and as much in alignment with theY lrespective pulley wheels 48 as practicable, are slieave wheelsy 55,

to each of which'one end of a flexible connection 44 is secured as indicated at 56. Each flexible connection is adapt-ed to'be 'maintained in engagement with the bracket 45 on the end wall by means of a guide 57 secured to the outer sideof the door endwall 37, "as shown in Figure 3.g vf The shaft 46 is adapted Vto. be operated throughjmeans of'suitable rworm and kgearingv mounted in a casing, as shown conventionally atK, from a cross-sliaft 58, extended i. beyondl the respective sides'of the car, which Vhas its opposite end portions Vrotatably mountedY in suitable bearings,each bearing being carried by a bracketplate depending ing of a well'known form.

Atransversely extending shaft 62 having a worm and gear connection withV the shaft 47 as 'best shown conventionally `atn63 in :Figure- 2. Each shaft 62 has `an ,end'extendedv beyond the side of the carl and is provided` with suitable ratchet mechanism for operating and loclingthe `same aslindicated conventionally at 64. The lratchet mechanism l G4 is supported .from a plate 65 depending e, Y ce from its corresponding side A of the c ar, and

Vsaid plate is suitably braced toits adjacentl cijessbeain section `132. The longitudinal shaft is supported in ysuitable bracketsf mounted the endsy of the respective cross# vfurel@ i f The'combination of the two doors F and beam members 31 andlSQ, as shown in Fig- `Gto close a single discharge opening provides `for a very large section of sloping floor movable froiii under the load for the purpose of inducing a ready flow vof the lading-in the car 'and preventinglarching of the load across l ythe door-opening. In cars of the type adapti ed to' be used in-ballasting operations it -is necessary-that the discharging loadbe always'under perfect control ofthe operator y a lsteady flow, but in order to secure the necessary control of the discharging material to 'prevent` flooding of the rails during ballasting operations'it has been customary in certain :types of cars to limit the flow of-material by providing la very small door opening.

In this invention, however, l provide a greater extent of movable floor thanhas heretofore vand still issue from the discharge opening in material flowing over the lower portion G lof l thexfloor, and thus preventl the free flow of l, thelading from thecar until such' time as4 the member G is inclined toa position below the horizontalplaiie yas indicated in Figure 5 when the flange 234 atl the free edge thereof willi-act yas a guard to prevent the heap of ballast adjacent the rail from overflowing the rail.v Thelparts are'fso arrangedthat when the ballast commences toy flow freelyV over the edgeof/tlie door the heap of ballast sloping from the flange v234 at the swinging edge of 'the door towards the rail will be below the flange ofthe wheels,'assuming the bal'lasting for ballastingmaterial. ,Y l .Assuming the doors tol be in closed position and," it is desired to ballast'bet-ween the material lies'atthe natural angle of repose trally disposed shaft 46, thereby lowering the doors-:Gf As the doors G open, the upper doors yFl will falso open inv vunison therewith due to the connections 38y between the said time as the door G is depressed below the horizontal plane indicated at 67 in Figure'4,

The operation ofthe side doors by means)` ,of shaft 47 is effected by means 0f a yshort f "rail when the slope oftheheap of ballast ma- Vterial at the natural angle of repose is below n thetop of ther railf In' order to guard against Vthe possibility of the'rail being flooded Vfrom anundue flow ofmaterial over the side edges thereof the members'G are extended an appreciable distance' beyond the hopper end wallsthereby forming4 ledges which retain y 1 hopper i et' the.
