This invention relates to improvements in dump cars.

The object 01 this invention is to improve the construction of dump cars and extend the usefulness of the same to various kinds ingthe length of door openings intermediate of the tracks, and permit the car to be utilized in services usually performed by flat floor gondola cars, such as haulinglengthy, or other specialrmaterials.

Tlieinvention further consists in the improvements in the parts and devices and in the novel combinations of the parts and devices herein shown, described and claimed.

In the drawings forming apart of this specification, Figure 1 is a broken side ele- Qvational view of a portion of a carshowing my improvements in connection therewith. Figure 2 is a top plan view of that portion of the car illustrated in Figure 1, the dumping doors in this View beingomitted for the 1 purpose of showing the arrangement of the door at the end of the car.

Figure is a vertical sectional View through the car on a line correspondlngsubstantially to .a .l1ne3-3 of Figure 2, said view showing the dumping doors in center discharging position. Figure 4 is a view taken on a line corresponding substantially to a line 44 of Figure 2, said view particularly illustrating the arrangement of the doors and mechanism for side dumping. Figure 5 is a vertical, sectional, partly elevational, view of the end of the car taken on a 'line slightly to one side of the longitudinal center of the car, and illustrates the end construction of the car. Flgure 6 1s a fragmentary side elevational View of the end of the car as.

AA denote the side walls of the .car including side sheets 10. stakes 11, and reinforcing angle shaped bulb members 12 disposed along the lower margin of the side sheets and secured thereto; B indicates the center sill construction, which 1n the 'form shown, comprises a plurality of channels 13 l3 and a plate 14 forming a girder-like structure; and CC denote fixed transversely extend ing walls adjacent each end of the car, dolining theoppositev ends of dun'iping hop:-

pers, each o't' said walls havinga vertical section 15, and sloping portion 16, "the upper edge of said sloping section being secured to and supported by a transversely extending beam member 17 connected to the center sill structure, andto the reinforcing marginal bulb members 12 of each ofthe car side walls. Intermediate the 'tranverse Wall sections Cthe can is provided with a hopper constru tion, which includes four hoppers D, longitudinally arranged inpairs on each side of the center sill, -the hoppers'be'ing separated tronieaeh other longitudinally of the car by a transversely extending hollowcross beam"; structure The. cross-beam structure E is preferably formed, of plate sections 1818 disposed on opposite sides of the center sill and partly supported by a beam member 19 which extends across "the plane of the center sill and is connected thereto and at the side walls of the car. Each section 18 is preferably of inverted V' shape presenting inclined wal'1s20-'20 Which slope away from each other, and include lower vertically depending portions-21, the sections 18 defining the inner end Walls I of the hopper sections D. As most clearly shown in Figures 2, and 3, each hopper section D includes an outer downwardly and inward-1y inclined side hopper sheet 22, secured to the adjacent side Wall, of the car as indicated at28 and is-suitably braced and rigidified. The opposite side of each hopper section D inoludes an inner downwardl'y and outwardly inclined hoppersheet 24, the hopper sheets 24 tor all of the hopper sections being preferably in the form ot'a unitary. structure carried by the center sills B and suitably rigidified longitudinally by means of angle members :25 secured to the respective sides of the center sill structure 13 by means of brackets 26. The remaininn" portion of each hopper bottom section D is formed by .a movable load discharging door or movable floor member Ewac'lafplted to assume a substantially horizontal position when "in c'losedv pesition, and adapter'l to have alternative )ivotal and swin in movement at its opposite sides so as to'permit tilting of the door in either of two desired oppositedirections, or to permit of both sides ofrthe door being lowered simultaneously to allow lading to discharge on either side ofthe door; These features of my invention are in many respects an improvement on my United States Patents Nos. 825,580 and 825,-

i 581, dated July 10, 1906.

In the constructionscovered in these patents, the doors are arranged for operation by mechanism disposed beneath the door, requiring the disposition of the door adjacent the top of the 'operated for center dumping.

' cent-er sill, and necessitating a large opening to-clear the center sill when the doors are Furthermore, in such an arrangement the height of the door from the railv renders it useless for safe and economical ballasting. I overcoi'ne these deficiencies in my present invention by ;mounting the load discharging floors adtion and for this purpose each door section j acent the lower portion of the center sill, and disposing the operating mechanism above the doors. V r

As most clearly seen in Figures 3 ands, the doors E are adapted for operationfby means of longitudinally disposed shafts 27 and. 28 respectively disposed under sloping floor sheets 22 and 2d onboth sides of the car, and since the shafts and operating mechanism are'similar, the same reference characters willbe utilized to designate similar parts of the same. Said shafts are con- 'nected with the doors by means of self-locking linkage mechanism F which includes a is adequately braced longitudinally by means of beam members 32 preferably in the form I of Z-bars. The beam members on the oppo site sides of the door are connected by transversely extending stiffening members 33 through the medium of gussets 34;, and bracket members 35 are disposed outwardly of the beam 32 to support the overhanging I portion of the door. The longitudinal beam members 32 are extending at each end a.

limited distance beyond the door plate and a bracket. 36 secured to the web and lower flange of the Z-bar 32. Said bracket '36 is provided with a transverse wall 37 through which a pin 38' extends, whereby the link 29 of the door mechanism F is connected with the door. The pin 38 is extended longitudinally of the door and maintained in fixed relation with the bracket by means of a rivet or bolt 39 causing the pin 38 to function in effect as a fixed trunnion. The

bracket 36 is also further braced by a longitudinally extending depending flange d0.

The floors E, as shown, are preferably formed in two groups'longitudinally of the car and'intermediate said groups a cross shaft 41 is provided which extends to the sides of the car. The shaft 41 is for the purpose of operating the floor doors E for center dumping, and for this purpose it is operatively connected by means of worms 42,'and gears 43, to the shafts 28, it being the preferred construction to open said doors for center duin ain in unison as illustrated in Figure The worm and gearing for each shaft 28 is supported in a housingl ld carried by a bracket plate 44 which latter is carried by the center sill and the transverse beam member 19. At the sides of the car each end of the shaft 4-1 is supported in a bearing 4L5 which depends from a vertical gusset plate 46 carried by the side of the car, and braced to the sloping floor hopper sheet 22 by means of flanged gussets 47. Any suitable shaft locking and rotating means may be used'at the ends of the shaft,

but the shaft is preferably locked at each end by means of locking pawls 4:8 acting on ratchet wheels 49 fixedly mounted on shaft 41, said pawlsbeing operable in unison by means of a transversely extending shaft 50. Outwardly of each said locking ratchet wheel there is provided an operating ratchet- 51 with which may be associated a suitable shaft rotating pawl and lever (not here shown).

The arrangement permitting opening of two hopper doorssimultaneously provides for a safe and convenient arrangement for ballasting purposes as the lading from the respective hoppers flows towards each other as indicated by the lines 5252 and thereafter [lows from the free edges of the doors to "aid the rails. as indicated at 53. Battle plates 54; at the center of the car and 69 at the ends of the hopper section extend in a transverse vertical plane at the end of each doorto prevent an undue flow of material at the ends of the doors.

The preferable arrangement for opening the doors outwardly to discharge at the sides of the car provides for opening one door independently of the other. For this purpose, the shaft is operatively connected by means of worm 55 and gearing 56 with a short transverse shaft 57, which is supported by means of a gusset plate 58. The worm 5.3 and gearing 56 is disposed adjacei'it the end of a hopper section and supported in a housing 59 by means of a gusset plate 60 carried by the aforesaid gusset plate 58, and a fixed floor section 61 which extends from the end of the hopper towards the bolster G of the car. The transverse operating shaft 57 carries a locking ratchet 62 with which cooperates a locking pawl 63 adapted to be locked in position"by a cam 64-, and outwardly of'said locking ratchet- 62, there is an operatingratcl-iet 65 with wliichsha'l't' rotating means (not shown) is adapted to co-operate. Each operating shai't 21 1s supported beneath the cross-beam E by means of a bearing (ificarried by a gusset plate 67 supported by'the transverse beam 19 and the gusset plate 46, and at the end of the shaft 2? remote from the worm and gear, a shaft bearing 68 is provided which is-supported from a transverse bafiie plate 69. The battle plates (59 are disposed at the ends of each related hopper section, and extend between the center sill and the side of the car, and are secured to both of said members. Art the operating end of the car the worm and gear arrangement constitutes a carrying means for the shaft. The shafts 28 which operate the doors for center opening are supported beneath the'crossbearn E bymeans of the worm and gear housing M and at the ends of the shafts by means of shaft" bearings 70 which are carried by the transverse battle plates '69:

its all the arrangements of door operating mechanisms F and relatet. parts are-the same, the desc-ri )tion of one will suffice.v Each of said mechanisms includes a polygonal Winding drum- 71 fixedly mounted on the shaft in connection with links 72, 73, 74

and the terminallink '29 adapted to wind aroundsaid drum, the link 74 having a looking shoulder 17d adapted to engage a looking shoulder 7 5 on the drum, and the'terrm nal link 29 having a bent end 30 hinged to the link 74: directly over the center of the drum when the mechanism is wound upnto its maximum extent; 'With this arrange ment of door voperating mechanism, it will be seen that the door E hasa pivotal move- I ment about the pivot 38xindependentlyy of the release of the door mechanism and it will be further seen by reference to Figuretthat as the door is-opened the thrust of the load against the door, which is in the: direction of'the arrow 76, tends to force the terminal link 29 rearwardly against one of the walls of the polygonal drum 71. As the pivot 38 about which the floor pivots is below the level of the door'fioor, the floor door plate is-formed to curve on a radius 138 described with the pivot 38 as a center and the dooris'extended somewhat beyond these pivots and also beyond theside walls 22 and 25 of the hopper which serves to eliminate any crack or aperture between the door and the framing when the former is open as well as providing a longer door which serves as an extension to throw the lading further away from the'rails, said lengthened" door being particularly advantageous to restrict the flow ot the material when depositing ballast. The sets of mechanisms F on the opposite ends of each floor E. are adapted of the car.

This arrangement o discharge doors and door operating, mechanisms is an extremely convenient and economicalone from? an op erating standpoint asthe load may be discharged either centrally of therails or to the sides of the car without the necessi of con verting the cars are predetermined'manner but it is also obvious that the uscot releasable doorsupporting-means at the twoedges' of thedoo-rs involves additional expense and having a large lioad oarrying space at' the ends of the car. Forming a portion ofthe level floors at each end'ofthe carover'the tracks is a movable member? 77 which is preferably hingedly mounted at 78 adjacent the upper edge of the transverse end sloping floor 160f the hopper-portion and adapt the said member 77' for placement in an in clined' position as indicated by dotted lines in Figure 5. Such floor is preferably maintained in the inclined position braces 79. which are pivotally mounted to fixed brackets 80 and maybe bolted or otherwise secured to the under-surfaceof the movable fioor as at 811' 1 A-su'bfioor' is provided beneath the movable floor section by means 0tfloor'platesfil and'161 and'thetop of the bolster G being-raised :somewh'at; above the plane of the said subfloor forms a support for the movable floor section 77 W hen the movable floor sections at the respective ends of the car are positioned"- as portions of a car adapted for service as a level" floor car; each of the members 77' rests on the bolster G with the" upper-"surface substantially in alignment with fixed floor sections 82 each of which extends outwardly from the end ofthe member 77 tothe end of the car, thereby giving thead v'antage and equivalent of a flat floor car fonthe conveyance of long material',' suchas" lumber, and for'this'purpose' the top of the center ridge and transverse ridge E which is formed with "a narrow fiat surface 83*, are substantially on the same level-as the flat floor port-ions over the truck. Vvl'ienmaterialsuch as coke which occupies considerably more space for a given weight'tha'n the majority'of dumpable 7 materials suchas- 5 hopper portions D, and for the purpose of facilitating unloading ofthat portion of the load adjacent the ends of the car a swinging side door 83 is provided in the side wall of the car at each corner adjacent the ladder. It will thus be seen'that the car will perform the service of the usual hopper in either center Or side dump and be available as a ballast car and also perform the service of alevel floor gondola car.
