17 Claims. (01.105-251) H y H p y The invention relates to railway rolling stock Figure 10 is a vertical longitudinal section and Y and more particularly to hopper cars, and consists in a novel hopper and hopper door construction including associated c'ar underfram'e parts and accessories.

One of theobjects of the inventionis to provide a hopper car construction approaching the maximum capacity possible for such cars, but at thesame time arranged to discharge. the 'carload between the rails or-outside of the'rails; as

. desired.

Another object of theinvention is to provide hoppers having sides and discharge openings of greater length than are usually provided without detracting from the rigidity of the underframe and without making the underframe sills and hopper walls of substantially heavierconstruction .than ordinarily required.

Another object of one form. of the invention is to provide a simple, eiiective door operating mechanism which eliminates winding shafts,

chains, rat chets, etc., and includes simple, rugged parts formed integrally withthe doorand-hop- These and other detailed objects as willbe referred to'later are attained by the structures illustrated in the accompanying drawings, in which-- i w I f a Theleft hand portion of Figure 1 is a top view of the car underframaandthe right hand'portion is a top view of the car body.

Figures 20;21 and 22 are transverse sections through 'modified constructions illustrating. .dif

ferent center sill arrangements and, in Figure 20, illustrating a 'difl'erent door arrangement. 1

In the'constructi'on shown in Figures 1 to 8, inclusive, the underframe comprises a box sec- 'tion center sill having side walls I, a bottom wall '2, and a convex top wall 3; and including out wardly and downwardly-inclined webs l forming theinner sides of the-hoppers.- Depending from andinwardly inclined webs 8 forming the hop per outer sides. The sidesillandliopper' side structure 1- -8 include depending brackets 9am ill for mounting door'op'erating mechanism.

The underframe includes bolsters ll bywhich the car body is mounted uponthe tr'uckindicatec'i 'by the wheels [2. Intermediate the bolsters is a central transom-like structure including spaces vertical 'webs l3 and aninverted V-shaped top plate M. Between thestructuretli-M and each bolster isga web l5 havinga vertical portion and an inclined portion. Webs 13, it and'lti form the ends oi the hoppers and also"transverse transoms of the underi'rame structure. Prefer-'- ably, all of the parts referred tolabove are cast strength for a given amount ofmaterial is pos sible and 'theflaborand material required for assembling separately formed parts is eliminated and the necessity of irequent inspection'and tighteningin order tomaintain the rigidity oi. the structure is avoided; p

The construction described, when applied to integrally with each other whereby-maximum a car having the outside dimensions common to large capacity railway hopper cars, provides for narrower center and side sills than previous constructions, and produces four hoppers of substantially greater area at the top than the usual hoppers and each having a large opening at the bottom of a length substantially greater than its width.

To reinforce the underframing in view of the large hoppers, there are provided transverse ties each having an inverted V-like top member I! extending substantially from side sill'to side-sill .and merging withthe webs 3 and 5.;Each tie a also includes a vertical web l8 merging with the center sill webs l and with the hopper walls 4 and 8. Vertical webs l8 arereinforced by suite able ribs l9.

Triangular braces 29 are located in the angle formed by ties and the, sides 2| of the car superstructure and, preferably, are welded tov these parts. These bracesextend from near thetop of the car sides to points on the ties l1-l8 near the center sill structure and cooperate with the remainder of the underframestructure to rigidify the underframe and contribute towards hoppers that will maintain their contour notwithstanding the large area oftheir dischargeopenings. 3 Each door structureconsistsof two sections 22 and 23. Each section 22 extends between the transverse webs l3 -and. l5, while section 23' extends just beyond elements l3 and i5. Integral lugs 24 and 25 on door sections 22 and 23, re: spectively, aline with corresponding lugs 25 provided on webs l3 and I5, and'pins' 21 extending through lugs 24, 25 and 26 form pivots for the adjacent edges of the door sections. The unpivoted edges of the door. sections are raised and lowered by means of chains or cables, indicated section.

at 28, passing over sheaves 29 and, wound on drums 30 by any familianshaft and crank or ratchet arrangement. I

As best shown in Figures 3 to -6, the door sections may be manipulated to discharge their load outwardly or inwardly of the rails. To seal the two-part door structure against lossof material .when the hopper openings are closed the two door sections cooperate to form an efiective joint. The lower edge of section 22is curved, as,at 32. aboutthe pivot axis and the bodyfof section 23 meets the flat portion of section 22 before the curving of the latter starts. Aflange 33 on the lower edge of door section 23 overlies the curved clined surface over which the load may pass irrespective of the arrangement of doors for dumping eitherinslde or outside of therail.

The general arrangement of the underframe and hopper sides in the modification shown in Figures '9 to 19is the same as that previously described, but the door construction and assembly and operating arrangementv differs from that described above; Each door includes .a convexly arched top plate 40, curved about an axis coinciding .with the door pivot 4|, and side plates 42 dependfrom the outer edges of top plate 40 and converge towards a point substantially below the tion or to closed position. I I An'arcuate reinforcing flange 59 rigidifies the levelof the door pivots. The door may be tilted in either direction from the hopper closing position shown in Figure 11 to a position in which one of the side plates forms a continuation of the hopper inner side 43, or to a position in which 5 the other side plate 42 forms a continuation of 'the hop'per outer side 44..- The underframe transom 45 has an offset depending triangular extension' 46 terminating in the bearing 41 for one of the door mounting pivots 4|. 1o A vertical web 48 depends from the inclined end wall 49 at the-other end of the hopper and includes a similartriangular extension 50 terminating in .a bearing 5| for the other door pivot pin 4|; The intermediate tie 52 has a lower por- 15 tion terminating in an arcuate section 53 for. accommodating the arched top plate of the door. j The outer'end wall 39 of each door (Figures l6- l9) is provided with extensions 39a projecting'at each side beyond sides 42"a'nd having an 20 integralgear or rack 54 and the vertical web 48- has enlarged portions 55' for journaling'a shaft 55' for the worm 51 which meshes with the 1 gear 54 whereby the door may beoscillated in.

' either direction'to open to either dumping posi- 25' end ofthe door and protects the teeth of gear 54,'an'd the ends of this flange are turned inwardly, as at 59, to form stops for abutting a lug 50 on the web 481 to limit the movement of the door. The lowermost portion of wall 49 is offset, as indicated at B I, to accommodate the end of the door similarly to the offsetting of projection 45 on the center transom. The stops 59 are spaced 35 substantially sidewardly of the door side .walls42 so that the door will be in'the full open position when either stop 59 engages the center stop 50 (seeright hand side of Figure 11).

. By pasting the door top plate, side plates,- pivot 40 1 bearings, and gear teeth as a unit, and by casting the hopper end "wall 49','web 4s, 'bearings55 and lug 69 as a unit, the structure is simplified and made veryrugged so as to adequately withstand'the forces incident to the rough handling 45 of heavy, material which characterizes-the use of cars of this type. As previously indicated, as-

sembling and maintenance costs" are minimized.

' Figure 20 illustrates a modified structure'in' which the center sill comprises a main vertical 50 web 55 havingaheavy bottom flange 55 extending on both-sides thereof and also having a top flange or flanges 51 extending downwardly'and outwardly in opposite directions from the longitudinal center line of the car and forming the 55 hopper inner sides. Flanges 51 are thickened where they merge with the vertical web 55 and thus provide adequate sill'strength without neces-" sitating a joint in the hopper side or a heavier hopper side plate. Suitable transverse web s 54 60 brace the remainder of the sill and hopper side structure. 'The topplate 59 of the door corresponds to the top plate of the door shown in Figure 11,;but

the door side plates 59 merge-with each other 3 immediately below the .dooraxis 10 and a downwardlyprojecting flange 'll forms a hopper extension deiiector which serves to cIearthe rail, when the contents of the hopper are discharged, irrespective of the directionvof the discharge.

' In the modification illustrated in Figure 2l, the centersill proper 12 corresponds to that shownin v Figures3 and 11, but the hopper sides 13 extend." downwardly and outwardly from the arcuate'top wall 14 of the center sill instead of from the lower corners of the latter. This permits the door to be located a greater distance from the rail than is practical with the box section center sill and hopper sides previously described. Transverse ribs 19 brace the hopper sides from the center sill. Figure 22 illustrates a modification embodying a substantially triangular shaped center sill 15 having upwardly and inwardly inclined side webs l6 merging in an arcuate section 11 and with the hopper inner sides '18 extending outwardly and downwardly from the lower corners of the sill.

Each of the forms of the center sill structure illustrated possesses certain advantages which may be of relative importance according to the requirements of the capacity and service demanded of the car, but all of the structures described are adapted to attain the main objects of the invention set forth in the introductory portion of the specification. Various other modifications and details of the sill, hopper wall, and door construction may be made without departing from the spirit of the invention and the exclusive use of all such modifications is contemplated.
