Ivention is not limited to the 4enact details of construction shown and described, as 1t 1s obvious that various modifications thereof Will occur to persons skilled 1n the art.

In said drawings: Figure l is a plan view .of the car, partly broken away to disclose a portion of the underframe. Fig. 2 is an inverted plan view of the underframe. Fig. 3 is a plan view showing the articulated truck upon which the car body is supported, the outline of the latter being indicated in dot and dash lines. Fig. 4 is a side elevation of the ear. Fig. 5 shows approximately onehalf the car and is principally a central longitudinal section but is in side elevation at the middle portion of the car. Fig. G is a transverse sectional View taken on line G-`G, of Fig. 4, and illustrates the means for iniparting the buihng and pulling stresses to the truck. Fig. T is another transverse sectional view taken on line 7*1' of Fig. it, disclosing the means for carrying and guiding the car body upon the truck. Fig. 8 is a detail plan view of that part of the carrying and guiding means which Ais carried by the truck, a depending portion from the car body bearing plate being also shown in section. FiO- 9 is a diagrammatic view in cross l,section of a typical Vore dock, indicating the method of the transference of the lading from cars to the holds of vessels; and Fig. l0 is a fragmentary plan view of the deck,

. showing the equally gaged rails of the trackage, and also the openings to the ore pockets arranged therebetween.

' Theobject of the invention is to provide a hopper car whichmis especially adaptable to the.ox"e-carrying`I trade, the' car being so arranged that its Alading may be discharged into pockets or receptacles spaced apart a predetermined distance.

The transportation of ore from the mines to the docks at the Great Lakes and the unloading of the ore from the cars on .the docks into the vessels, or into hoppers which discharge into the Vessels, is an important problemvin connection with the economical production of iron and steel, and the railroad companies engaged in the transportaY tion of ore have erdeavoredY to simplify tl'." handling of the ore as much as possible. 'l that end the Duluth, Missabe & Northern Railway vhas at Duluth large shipping docks, each dock being about 2,300 ft. long, with something lessthan 400 ore pockets, and the total storage capacity of these pockets is nearly 270,000 tons. The equipment for carrying the ore from the mines to the docks includes a large number of steel and wooden cars, which are especially designed and of such length and width as to facili- A representation of such docks is shown in Figs. 9 and l0. The docks C are elevated a considerable distance above the water level, and along the upper decks D of the-se docks tracks are provided on which ore cars E travel, the tracks being so disposed that cars may run upon any two .of the rails; that is to say, where, four rails F are laid, the inside rails may serve' as an intermediate track, o1' either outside rail and the inside rail next to it may constitute another track. Thus, the gage between all of the rails being of the same standard, with proper switching to avoid interference of cars, the lading may be distributed transversely of the dock in all the pockets to utilize the en-l tire capacity of the latter. Between the rails openings G to the pockets H are provided, Which openings are nearly equal to the distance between such rails, and at intervals longitudinally of the tracks, bridges I bridges men may stand while engaged in poling the ore. The men who use the bridges are provided with long poles, which are used in breaking bridges of ore which may form in the pockets While feeding the ore through chutes J into the holds of the vessels used in .water transportation. Because of the fixed sizes of the openings and the distance apart of such openings longitudinally of the tracks, and the impracticabiltyof altering the expensive zand permanent construction of such docks, ithas been found that cars of relatively small capacity were best available for this ore-carrying (service. This vhas largely increased the number of cars necessary, and because of the disadvantages incident to handling va large number of small cars the present invention provides in a single car twin hoppers whicln are spaced apart a predetermined distance longitudinally of the car, so as to permit both of such hoppers to register with the' openings in ,the docks leading to the or'e pockets.

An articulated truck especially adapted to cooperate with the predeterminedly spaced hoppers of the present car is fully disclosed in a companion application tiled on an even date herewith, under the title of Articulated Truck, and also partly shown in the drawinor of the present application.

y reason of th arrangement shown I am able to carry in one car as much ore as has heretofore been carried in two separate cars, and am able to discharge the lading at the docks with equal or greater facility than where two cars'arc employed at the same time, and provide a structure which is better adapted to railway service and one which can be used on roads having sharp curves, such as are common in the orecarrying lines which lead froin'the mines to and onto the docks.

Because ot' the. construction of the car illustrated iu the accompanying drawings` such car will carr)y heavy loads with a Illinimum ot' strains on the bod)v because each pair otthe supporting bearingr plates for the car body, located toward opposite ends of the car` can be placed at or near the transverse center plane ot the load at its respective end. so that the load at each hopper will practically coiiutcrbalance itselt` above the points ot support.

lcl'erring specifically to the car body, it will be noted that the car bodyv consists of two hoppers whiclrare spaced apart b v means ol the deckV plate ll, ,shown in plan in Fig. l. llach hopper comprises an end plate lll. sideplatcs ll and sloping inner end plate lL. The plates lll and ll are. vertical l'or sonrdistance l'rom their tops and then bent inwardly to a slope suitable for discharging the lead within the hopper` while plates l2 have a continuous unbroken slope from top to bottom.

Plates 12 of the spaced hoppers are connected by the deck plate B, which, likepthe side plates 11, is connected with the top chords 14, whichmay be Z-bars, ofthe car sides. Plates 1Q and B are stiflened and reinforced 'by members 15, 16 and 17 of any suitable shape and dimensions, but here illustrated, respectively, as channels and angle irons, these members being secured to the car' the central part of the truck may be inspecty ed when desired.

The side and end plates of the car body are riveted to side top chords 14 and end top chords 21, the latter also preferably made of Z-barsQwhic-h chords at the corners are connected by corner pieces 2Q withr their inner edges ona slope 28, to facilitate the discharge. of the load, and, to the same end, the vertices ofv the inclined portions of the hopper corners are provided with triangular shedding surfaces 2.' n.

The side. and end plates are connected to side sills Q0 and end sills 24 by stakes 25 and 2G, respectively, corner posts 27 connecting side plates and end plates and being attached to side sills, and filler posts 28 rest upon the side sills and support sloping. parts of the side sheets 1 1. the whole forming a strong` and substantial combination for carrying heavy loads and withstanding severe service stresses. Y

The side sills Q0 and end sills 24 are of box girder construction,'preferably made up of commercial channels and plates of suitable sizes connected in a strong and substantial manner. as by top and bottom cover plates or by properly distributed tie plates, the filler pests L and certain castings serving as tie plates. in the car illustrated.

'l'he end sills are covered on top by plate threugh which pass cud stakes Q6, as shown in Figs. l. il and 7.

'.lo the bottom of the end sills and the extremities of the side sills are secured strong plates S0, to which are riveted castings 3l. which serve as striking plates and also as containers of the draft rigging. The castings Ill. are designed to cariv twin dra l't riggings ot' suitable construction and size. though such draft rigging' is not material to the present invention and is not illustrated.

Members 32 of suitable shape and size,y

commercial channels servin well, are secured to the side sills and plates 30 to stiffen these ,plates and to prevent buckling. The members 32 are disposed in such position as to serve as a support for the sloping lower portions of the end sheets of the hoppers. `Below the sloping parts of the outer hopper end sheets 10 and the inner sloping hopper sheets l2 are vertical sheets 33, best shown in Figs. 5 and 6, which vertical sheets are secured to the lower portions of said hopper sheets l0 and l2 and serve as guides for the discharging load in unloading the car.

- Each hopper oiening is closed by a pair of doors 3, Whic doors are hung on hinge butts 35, or the like, which are secured to the side sills and side hopper plates, substantially as shown in Figs.. 5 and 7, and the door operating mechanism may be of any suitable kind.

To the bottom portion of the side sills, approximately at the longitudinal center thereof, vare secured one on each side`of the car strong castings. 36, which 'are used in transmitting pulling and buiiin stresses from the car body to the truc These castings it and slide transversely in castings 36a on the truck and control rollers 37, which rest on the truck castings, but as such castings are not intended to carry any material part of the load under normal conditions, some vertical clearance 1s left `between the car body castings and truck castings, and also between the rollers and car body castings. If lfor any reason the side sills of the car should sag so much that the castings bear against the rollers, it will bring such rollers into action and prevent jamming. To the side sills are also secured four bearing-plate castings 38, having vertical downward projections 39, which castings constitute carrying and guiding means bctivcen the car body and truck, as they rest upon and slide over the rollers 39 in the truck-bearing castings 38a, while projections 39 slide longitudinally in the truck castings which thus control transverse movements of the car body. Socallcd bearing plate castings 38 are secured to the side sills at points to correspond With locations of truck-bearing plate castings, which thus equalize the load on the truck wheels. The details are shown in Figs. l, a" and At the ends of the car even with thc lop chords of the car body are placed wooden platforms l() secured to and supported ou bars all and brackets 12, which are secured to the ends of the car body. See particularly Fig. 5.
