lily invention relates to s dump-cer; and the object of my invention is to construct e simple and inexpensive car adopted for con ryingr nd or gravel or materiel used for rood ballast and which our is so arranged es that its lood may be'evenly distributed on eech side ot' the cor-tinck.

A further object ol my invention is to en range the levers that maintain the doors in the bottom of the cer in e closed position in suitable hearings on the hody-bolsters and theneedle-beoms und to operate ell of seid levers simultaneously 'from a centrellymr ranged longi'tudinelly-extending shaft.

To the shove purposes my invention consists in certain novel tentures of construction and arrangement of parts, which will be hereinafter more :fully set forth, pointed out in my claims, end illustrated in the eccompanying drawings, in which- Figure l is s side elevation oi the leithand end of dump-csr el my improved construction, bothends thereoi1C being alike in con struction, Fig. 2 is o, vertical section teken longitudinally through the `center of the right-hand end of one of my improved dumpcers: Fig. 3 is a pien view orp one end oi the csr-freine, which irs-me comprises the side and center sills, end sill, bodysholster, and needle-besm, and also showing 'the mechmism for raising the doors end holding` them closed. Fig. l is e transverse section taken approximatelTr on the line i l oi Fig. 2. Fig. 5 is s transverse section teken approximately on the line 5 5 oi- Fig. 2. Fig. 6 is en end elevation of my improved dumucsr, showing the gearing for rotating the longitudinellyl extending slisltf ln the construction of my improved cer l make use of e pair of side sills l, the end sills'Q, 4the center sills 3, endinnnediately ebove the central pair of center sills is e. pair of licor-supporting sills fl. 4 supports en inverted'\!sl1eped floor or bottom 5, which extends longitndinelly y l throughout the 'length ot'tlie cer, end itslside mennen (the body of the cer, et suitable distances 'lhisV pair oi sills edges or lower ends rest directly noon the outer pair ol the center sills 3. The side sills l support the side wells o ci the cnr, end. the end sills support the end wells 7. All of the ports just described ol ordinary' wellknown construction.

Extending longitudinally through the cer between the sills 5 is e, continuous shaft 5, the ends of whichsnre suitshly journeled in the end wells 7 of the csr, and suitable inurnol-boxcs 9 nre arranged et various points throughout the length oi the cor between the sills '/l. it one end ot the cnr this shalt S projects e short distance, and mounted on seid projecting end is :i ratchet-wheel l0 end o gezu\vlieel ll. .fi pewl l2 is pivotslly errenged to one side ol the ratchet-wheel l0, the point oi which pnwl engages the teeth ci' seid retchetwheel. The gear-wheel il is driven by suitsble gearing i3, which lostmentioned gearing is operated by hond wheel lll, suitably journeled on the end ol' the cer. Located et suitable points along the shslt 8 ere winding-drums l5.

Trsnsversely arranged beneath each end of the cer et suitable distances from the end sills 2 ere the body-bolsters 16, which ere preferably constructed ol' cest metal end which are secured to the under sides of the ide sills end the center sills 3 in any suitable Trsnsversely arranged beneeth from the body-holsters, ere the needle-beams i7, which are preferably formed of cest metal end which ere secured in any suitable men ner to the under sides of the side sills l end the center sills 3. These needle-beams ere providedwith downwsrdlypendi1ig portions 18, that serve as saddles or bearings for the truss-rods 19, which extend 'from seid needlebeams upwardly over the centrel portions of.

the body-holsters 16, and from thence to end through the end sills 2, and nuts 20 ere positioned on the end of seid truss-rods outside the sills 2. l

The spaces between the outer air of center sills 3 and side sills l ere norme ly closed by the doors of my im roved ser. The pairs oi doors between the ody-bolsters end the end sills are necessarily very short compered to IOS the length ot the doors between the bodyi holsters and the needlesbeems end the pour el doors between the needle-hesnis. Esch door comprises the loody portion 2i, wnich is of such a, size as to close its corresponding' opening, end secured 'to the underside ci each door is 'a pair of transversely-arranged laars 22, whiohfperforrn the function el' hinge vvand latch bars,land the inner' ends of said hars are hinged to brackets 23, which are secured to theouter faces of the outer pair oi eentensilis 3. All oi thesebars 22 on each vside of the car extend outwardly heyond the side sills l, so as to be engaged by hooks 24,

termed on the lower ends oi latch-levers 25, which are iulcrurned at their centers to the outside faces of the side sills l., and the up per ends of, each set'of levers 25 are pivotally connected to a longitudinally-entending to which is pivotally eonnected a latch 2Q for maintaining the hand-leverand the latehingleversv 25 in vertical positions. Vfhen the latch-levers 25 are in vertical positions, the hooks 24 on the lower ends thereof engagethe outer ends ot the hinged bars 22 and thus.

hold the doors 2i in closedpositions.

the inner faces of the end sills 2 and to the under sides of the outer pair of center sills 3 is a pair of' short transversely-arranged shafts 3i the inner ends of which terminate gust insi e the outer pair of center sills 3, an( Yahove said inner ends are 'lined laterally and u .es

outer ends'otthese levers 32 are the lower ends of chains 33, which pass upwardly over ypulleys 34, secured to the outer faces of the wardly projecting levers 32.l Secured to t 1e ninery pair of center sills 3, and from thence Av said-1chains extend upwardly and are secured to and Wind upon one of the Winding-drums i5. l'rlxed'toI the outer end of each shaft 3l is an upwardly-projecting inger 35, with the up, er end 0i which is formed a ball 36, that r1' es directly against .the under side of the corres` ending door 2L with t e sides of the body-holster. i6 are the pairs of horizontally-aimed lhearings 36, in

' each pair of which is arranged for rotation a SQ 'shaft37, Whichis equalin length to the shafts 3l, and the inner ends 'of said shafts, which terminate at points in longitudinal. alinement with the inner 'ends of shafts 3l, are provided.

with the laterally heut and upwardlyex tending 'levers 33. To the outer'ends of these levers 38 are connected the lower ends of chains 39, that extend 'upwardly over rollers el), vand from thence upwardly, where they Wind onto and are secured to the winding drums 15. Fixed' on the outer ends oi the shafts 37 are u Ward'ly-projeeting iin ers el, that are roviiled ,at tlfieir 'opper en sl with halls 32, t Aat hear directly against the under sides of' the doors '21. films the doors lstween theend sllsand the hodyieolst'ers are Formed integral- 'engaged by the halls on the ends ot the ingers and by the halls on the fingers 41 oi' that side of the body-holster that is adjacent the end sill.

Formed integral with each side of each needle-beam l? a pair of horizontallyalined bearings d3, and in each pair of hearings on each side ot each needle-hears is arranged for rotation shatt 441s. Fixed to the centerrof each shaft ed is an outwardlyand uprgaizdlyprojecting lever toI the upper end o which is secured the lower end of 'a chain 46, that extends upwardly and being fixed to and winding upon a corresponding one of the drums 15. .Fixed upon the outer ends of each of the shafts 4d. are the upwardly-projecting fingers 47, carrying the antifrict1onhalls e8 on their outer ends, which balls ride directly against the under sides of' correspending ones of the doors 21. Thus each in 'dividual door is provided with a pair of the operating-'fingers-such as 35, el, and f47- and all ot the chains-sueh as 34, 39, and 46 wind upon the drums 15 in the saine direction, so that the-doors all open and close sie multaneously with a corresponding rotation of' the shalt 3. :Arranged to rotate in-hearings 30, fixed to lt is necessary to form the shafts 31 and 37 in pairs at each end of the car in order to accommodate the draitrigging and draw-heads ofthe car.

' When the doors 2l oi iny improved ear are closed, so that the car can be loaded,

hearings on the upper ends of all of the iin- Ygers to elevate the doors, and said fingers are maintained in vertical positions by the engag'ement of the pawl l2 against the teeth oi the ratchet-whee 10, thus preventing a backward rotation of said shaft 8. The nooks 24 en age the outer ends of the hars 22, and thus lthe shaft 8 is rotated so as to cause the hall'- ICC ho d the doors locked Ain closed positions.

When it is desiredtodurnp a loaded car, the pawl 12 is disengaged from the, ratchetwheel 10, after which the hand-levers 27 on each side ot the car are. engaged, and after the latches 2,9 have been elevated the hand-levers are pulled to one side insueha manner as to disengage the hooks freni the outer ends of ythe hars 22. The weiofht ofthe sand, gravel, or other material in the oar will `as soon as thesefhoolrs are released cause the doors'to swing downwardly on their hinges, and in so doing all of the shafts 3l, 37, and i4 are rocked, and all ci the chains unwind :trom

their respective drums, necessarily rotating the shaft 3. Thus the floor or bottom of the oar is inclined in both directions andthe contents Aof said Aear automatically discharged. To close the doors oi ,the ear, the operator manipulates the hand-Wheel lll to'fdrive the recits/sl et the shafts 3i, 37, and se, wliie' gearing i3 and hy this ineens rota'tesfthe .shaft 8, Windlng the various eliairisn on the esame y earried by said shafts inte vertical positions, and as a result the doors are moved upwardly into horizontal positions, and then said doors are loelred by manipulating the hand-levers 27 so as to cause the hooks 2li on the lower ends of the latoh-leyers 25 'to reengage the outer ends of all of the hinge-bars 22.

My improved dun1p-ear :is simple in oonstruetion and operation, Vvery vevenly dis- Charges its load on each. side of the track, dumps automatically by the Weight of the load, and can be very readily closed after being dumped.

l. In a dump-oar, a ear-body, body-bolsters and needle-beams secured to. the under side thereof, bearings formed integral with the side faces of said body-holsters and needle-beams, rook-shafts journaled in said bearings, fingers fixed to the outer ends of all of the rook-shafts, dumping-doors hinged to the under side of the oar-body against which the lingers engage, means whereby said` dumping-doors.are held in a looked position, and means whereby all of the rook-shafts are simultaneously rotated; substantially as specified.
