1 claim.

My invention lrelates tor improvements in hopper bottom load discharging cars, and is especially related to a type of hopper car suitable' jfor commercial 'and for economic track ballasting services.

One of the objects oi my invention is to provide a 4car with a large cubic capacity in proportion to dimensions and weight for yhauling revenue pro-` ducing freight such as coal and for the economic and convenient unloading 'of such freight by the consignee at destination.

A further object of the invention is to providev a car for the transportation of and the economic placement of ballast upon the railway track.

A further object of `the invention is to provide Fig. 8 is an enlarged detail section of one end of a hoppenythis sectionnbeing taken on substan. tially the same line 2-2 of Fig. 5 to illustrate the relation vof the upper end flange of the ycar door withr the downward extensionvoi the end floors and to illustrate the transverseplates which carry the door hingesand which provide baiiles, at the ends of the hopper doors;

-illustrated'in Fig, 10

In-the drawingsfthe lower portion'of the `car body Afis shown,-having side sills A and center sillsy E, between which 'the longitudinallyv disposed discharge hoppers are located. The hoppers are disposed in pairs. Each hopper has two doors F' which are 'hinged together an a hinging rod 3 which, 'as shown more clearly in Fig. 5, is disposed substantially above the rail Rof the track so that the inside ror center doors of the pair of hoppers `willdirect the discharging load to the space between the rails and the outsidedoors will direct the discharging load outside of `the rails. Thus,

as ,i the car ymoves along the rails, particularly whenthe car is used 'for ballast material, this material can be placed either in .between or outf side of the rails, as conditions require. The end of each hopper isp-formed by afsloping end floor `sheet B and a sloping cross hopper sheet G at the center of the car. f i p The side Walls of the hoppers are formed by the longitudinally disposed side floor sheets C and the inside sloping hopper sheets D. These hopper walls are placed as low as possible in a car body to add as much. increasevin car capacity as possible,and in the present car it will be noted that the hoppers are vpractically within the yheight of the center sill and in substantially/.the same level therewith. Below Ythe hoppers arev sub-hopper portions which in effect constitute the hopper discharge outlets. These suiza-hoppersL are formed in Vgeneral by the doors vwhen closed, and by Vertical extensions B and Gf, respectively, of the hopper end sheets B and the cross hopper sheets G, as shown more clearly in Figs. 2 and 8, these extensions being V-shaped and forming end Walls for the sub-hoppers. These extension walls B and G extend downwardly into close proximity to the inner faces of the doors when closed. In this form they project below the edges of upturned flanges I formed at the edges of the doors. These door flanges'l lie outside of the extension walls B and G', and closely adjacent thereto, so that when the doors are closed the material in a loaded car cannot pass the ends of the sub-hoppers.

As hereinbefore mentioned, the doors F of each hopper are hinged along their adjoining edges on a hinging rod 3 which extends longitudinally of the oar beyond the edges of the doors and has bearings 2 in transverse door supporting andy baille plate members H. These members H, as shown more clearly in Fig. 8, are secured by rivets 4 to theunder sides of the hopper floor sheets B and G, and extend downwardly in a vertical, transverse plane to a, point considerably below the hinge rods of the door and are `positioned closely adjacent the door flanges I, so that they s sistent with clearance for movement of these door` braces. The plates are extended below sufcient to be cooperative with the door flanges when the doors are in open position so as to form and walls or ballles in the full open position of the doors.

In the center of the car beneath the center sills are ballast spreading plates J which serve to deflect and spread the top of the ballast pile between the rails. These plates lie inthe same plane as the baille plates H on each side thereof, and

they are joined together with the baille, plates H to form a transverse strengthening member. The baille plates H, as will be noted more clearly in Figs. 4 and 5,` have end portions H at their upper ledges, which overlie the spreader plates J and are riveted or welded thereto.

The spreader plates are joined to the center sills by means of angleA members J which are riveted or otherwise. secured to the plates and extend up into the center sill to which they are also secured.

In addition to the baille and spreader plates, there is also provided transverse diaphragm and bearing support plates K. These plates K are disposed immediately adjac'entand outwardly of the baille and spreader plates, and in substantially parallel relation therewith. They are flanged at K at their top portions and are secured by rivets or otherwise to the underfaces of the sloping hopper floor platesB and G. These transverse plates K provide rigidity and transverse strength to-the car members-and they also serve as mounting's for carrying a part of the door operating mechanism.. The sheave wheels 5 which carry the door operating chains are positioned between the plates K and the baille and spreader plates H and J-. These sheaves are rotatable on the shafts 6 which have bearings 1 in the plates K and the baille and spreader plates.- The center doors are operated in pairs from jointed handles I2 .located at points adjacent either side of the car. These handles are mounted on transverse CII shafts I3 which extend from side to side of the car just beneath the center sills and are mounted in suitable end bearings I3' provided for that purpose. The shafts I3 carry worms I4 which mesh with and drive gear wheels I5, both the worms and gear wheels of each pair being suitably closed in a housing I5. The gear wheel of each set is attached to and drives the longitudinally disposed shaft I'l which is located centrally below the center sills of the car and which has a suitable bearing at one end in the casting 22 which is mounted on the downwardly extending hanger plate L, the plate L being attached to and supported by the center sill. The other end of the shaft I'I has a bearing in the housing IB which encloses the worm and gear wheel. Between the spreader plates J and the transverse plate K at the ends of the hopper, the shaft Il carries winding drums I8 upon which the winding chains I9 and 2D wind in opposite directions when the shaft is rotated. These chains extend over idler sheaves 5 and are connected at their ends through the door brace extensions 4 through the housing and guide cast ings 2l. Thus the rotating of the shaft Il and winding drums winds the chains upon the drums and swings the center doors to closed position, and the rotation of the shaft in the opposite direction unwinds the chains and allows the center doors to open by virtue of the weight upon them.

The side doors are individually operated by winding drum and chain connections. As shown more clearly in Figs. fl, 5 and 7, longitudinally extending shafts II are disposed at the side of the car beneath the hoppers and mounted in suitable bearings therefor. These shafts carry worm and gear drive connections 9, mounted in suitable housings I and adapted to be operated by jointed handles 8. located conveniently for the operator. These shafts are provided with winding drums I0 for the winding chains It which extend directly to and which are attached to the door brace extensions 4 throughthe guide castings 2l.

I claim:

In a railway hopper car for the transportation of granular materials and having car Walls, center sills and sloping iloor walls, the latter forming longitudinally extending hoppers arranged in pairs, one on each side of the center ysills and having their longitudinal centers in vertical lines with the rails of the railway track, a sub-hopper below each of the said hoppersoomprising a pair of hinged interengaging doors having upturned edge flanges and disposed in a V-shaped relation with each other when in closed position, transverse plates suspended from the hopper iloors at the ends of the doors for supporting the doors and for forming bailles against overflow of the load from the ends of the doors when being moved from closed to open positions, a downward extension into the sub-hoppers oi the two sloping floor walls at the longitudinal ends of the hoppers and above the said sub-hopper doors whereby the upturned edge flanges of the hinged doors may sandwich between the baille plates and the downward extensions of the two sloping door walls to prevent leakage of materialsv from the car.
