HOPPER-IBOTTOMED BOX CAR.

Application filed December 5 This invention .relates to a new and improved railway car, and more particularl to a box car especially adapted for fac' 'tating the loading, transportation, and unloading of grain and similar materials.

More specifically, the car is divided into -a series of separate compartments, closed on all sides, each provided with one or more filling openings at the top, and having a hopper-shaped bottom for directing the material to a lower discharge opening; This opening is normally covered by a sliding closure, and below this is an angularly adjustable delivery spout for directing the Fig. 1 is a side elevation, partially broken -away, showing about one-half of the car, it

being understoodthat the remaining portion ofthe car is substantially a duplication of the parts here shownQ Fig. 2 isa top or plan view of this portlon of the car. j

Fig. 3 is aview looking up at the bottom of this portion of the car, and railway truck bein'g omitted:

Fig. 4 is a vertical central section, on a larger scale, through the bottom of the hopper and the discharging mechanism.

Fig. 5 is a perspective view, partly broken awa of one of the castings comprised'in the disc arging mechanism.

.Fig. 6 is a detail view of the rack and pinion mechanism for operating one of the closures, the view being taken substantially on the line 66 of Fig. 1.

Fig. 7 is a central vertical section taken substantially on the line 77 of Fig. 6.

The car, which is of the usual substantially rectangular box-car proportions, comprises an outer open framework 1, built up of suitable angle irons, and is supported on the usual railway trucks, one of which is indicated diagrammatically at 2.

I Supported in the framework 1 is the main body portion of the box-car,

plurality of transverse partitions 4 into a series of separate compartments 3, for holding the grain or other similar material. The

is built up of metal sheets or plates, suitably rlvete or otherwise secured to .each other andto the angle beams of framework 1. The partitions 4 not only,divide.

the car into the separate compartments 3, but also tie the sidewalls of the car together, preventing spreading and permitting the car to. be filled to the roof, which is not possible with the usual singlecompartment box car. The roof 5 of the car which serves as the upper closing wall for all of the compartments, is provided above each compartment with one or more (here shown as 2) filling openings, through'which the grain is poured into the compartment. As here shown, each, filling opening comprises a frame or casting 6, having upstanding walls "7, over which fits a closure 8 having downturned flanges 9, the closure being hinged at one side 10 to the roof of the car, and

provided at the opposite side with a suitable lock or latch 11.

The bottom of each compartment is in the form'of a hopper 12, formed of four in- J wardly sloping walls, converging at suitable angles towards a central discharge opening. Be ow each discharge opening is mounted a casting 13, best shown in Figs. 4 and 5, which has upper horizontally extending flanges 14, secured to and supported by a pair of the cross-beams 15,-which form a portion of the base of the car framework 1. Casting 13 comprises a substantially square or rectangular portion 16 havinga bottom horizontal wall 17 connecting with a downwardlyextending cylindrical portion 18 which terminates at its lower edge in an outwardly extending horizontal flange 19. A second inner casting 20 has upper horizontally extending flanges 21, mounted above the flanges 14 of casting 13 on the beams 15, and also has upwardly inclined flanges 22 which are suitably secured to the lower edges of hopper 12 so that the upper portion of casting 20 forms substantially a continuation of the lower end of the hopper. Hopper 20 is so formed that it terminates at its lower edge in a circular opening 23, somewhat smaller in diameter than the inner diameter of cylindrical portion 18 of casting 13. The outer walls 24 of casting 20 fit snugly divided by a within the rectangular portion 16 of castmg the bracket carried by a portion of the framework 1. A horizontal rotary shaft 31,

provided at one end with a crank or handle 32 is mounted in suitable bearings adjacent and parallel to one side of the car, so that the crank 32 is readily accessible to the operator standing at that side of the car. A gear or pinion 33, meshing with rack 28, is mounted loosely on shaft 31, between a pair of

collars

34 and 35, each of which is keyed to the shaft 31. Pinion 33 is formed shaft 31.

in one side face with an annular channel 36 from which extends inwardly a series, here shown as four, of radial'slots 37. A pair of similar dogs 38 are centrally pivoted at 39 in slots 40 in the collar 35. A spring under the outer arm 42 of each dog. tends to throw the inner end 41 down into one of the slots 37 Latches 51 normally hold the dogs in the full line position indicated in Figs. 6 and 7 so that their inner ends 41 will project into the annular channel 36, and

gear or pinion 33 may turn freely on the However, by releasing latch 51 from the outer end 42 of one of the dogs, the

inner end 41 of the dog will be moved down into one of the slots 37 thereby locking gear 33 to the collar 35 and hence the shaft 31. By suitably manipulating these dogs 38, the gears 33 may be connected or disconnected with shaft 31 as may be desired. It is to be understood that any other suitable form of clutch may be substituted for the one here shown and described, for connecting the gears 33 with the'operating shaft 31.

A discharge spout 43 has its upper cylindrical end 44 connected to a collar or casting 45 provided with an inwardly projecting horizontal flange 46, between which and the outwardly projecting flange 19 of the casting 13 is arranged a ball or roller bearing assembly 47 by means of which the spout is revolubly supported. The outwardly and downwardly extending end portion of spout 43 is supported upon an arcuate bracket 48 hung at its ends from posts 49 projecting down from the bottom of framework 1. By means of the mechanism just described, the spout 43 is permanently supported beneath the discharge opening of the ho per, but may be swung to either side of t e car to discharge the grain at the most convenient position.

It is to be understood that each compartment 3 is provided with the discharge mechswung open and the grain or other material is poured in through the openings. When. the covers 8 are again moved to closed posltion and locked, the compartments are entirelv closed and sealed. When it is desired to discharge a compartment, the spout 43 thereunder is swung to the desired position, and the dogs 38 corresponding to that compartment are manipulated to lock the corresponding gear 33 to shaft 31. Then by turning crank 32 closure 26 is slid out so that thegrain may be discharged from hopper 12 through cylinder 18 and spout 43 into the outer receptacle provided therefor. It will be noted'that as here shown, the operating mechanisms for two of the closures 26 are operated from the same shaft 31. If both gears 33 are simultaneously clutched to shaft 31, both closures may be opened or closed by the same operation of crank 32. Obviously three-or more closures might be similarly operated from the same shaft 31 and crank 32. j

A car constructed as above described, is simple and strong, and the compartments are almost completely closed at all times so as to hold and protect a maximum amount of material. The compartments are easily filled and emptied from outside the car, without the necessity of the operator, or any loading or unloading mechanism, entering the compartments at any time. The manu ally operated discharging mechanism is readily accessible from the side of the. car, and easily manipulated byv a single operator.
