fThe invention relates to railway rolling stock and more particularly to hopper cars, and consists in a novel hopper and hopper door construction. This application constitutes a division of our copending application Serial No. 671,854, filed May 19, 1933 now Patent No. 2,042,151, dated May 26, 1936.

One of the objects of the invention is to provide a hopper car construction with large capacity hoppers arranged to discharge the carload between the rails or outside of the rails, as desired.

Another object of the invention is to provide a simple, effective door operating mechanism which eliminates winding shafts, chains, ratchets, etc., and includes simple, rugged parts formed integrally with the door'and hopper.

These and other detailed objects as will be referred to later are attained by the structures i1- lustrated in the accompanying drawings, in which- Figure l is a top view of the hopper portion of a car embodying one form of the invention.

Figure 2 is a vertical longitudinal section and side view taken on the line 2--2 of Figure 1.

Figure 'Tis a longitudinal section through the door taken on the line l-l of Figure 6.

Figure 8 is a section inclined slightly to the horizontal and taken on the line 8-8 of Figure 3.

Figure 9 is a side view, and Figure 10 is a top view, and Figure 11 is an end View of one of the doors only.

Figure 12 is a transverse section through a modified construction illustrating a different center sill and door arrangement.

In the construction shown in Figures 1 to 11, in- 5 elusive, the underframe comprises a box section center sill'having side walls I, a bottom wall 2 and a convex top wall 3, and including outwardly and downwardly inclined webs 43 forming the inner sides of the hoppers. The underframe includes side sill-like elements I having as integral parts thereof downwardly and inwardly inclined webs 44 forming the hopper outer sides.

The underframe is mounted upon the trucks (not shown but indicated by the wheels 12) in any ordinary manner. At the center of the car is a Patent No. 2,042,1

central transom-like structure 45 comprising spaced upright webs and inclined arched or inverted V-shaped top webs. Between the transom 45 and each sloping end wall 49 is an intermediate tie 52.

Transom 45 has an ofiset depending triangular lower portion 46 offset outwardly of the discharge opening and terminating in a bearing 41 for a door mounting pivot 4|. The inclined end wall 49 includes a similar triangular extension 50 terminating in a bearing 5| for the other door pivot 4|.

Preferably, all of the parts referred to above are cast intergrally with each other whereby maximum strength for a given amount of material is possible and the labor and material required for assembling separately formed parts is eliminated and the necessity of frequent inspection and tightening in order to maintain the rigidity of the structure is avoided.

Each door includes a convexly arched top plate 40, curved about an axis coinciding with the door pivots 4|, and side plates 42 depend from the outer edges of top plate 49 and converge towards a line substantially below the level of the door pivots. The door may be tilted in either direction from the hopper closing position, shown in Figures 3 and 6, to a position in which one of the side plates forms a continuation of the hopper inher side 43 or to a position in which the other side plate 42 forms a continuation of the hopper outer side 44. The ofiset portions of transom 45 and end wall 49 have arched upper elements corresponding to the arch of the door, and the lower portion of intermediate tie 52 has a similar arcuate section accommodating the arched top plate of the door.

The outer end wall 39 of each door (Figures 8-11) is provided with extensions 39a projecting at each side beyond sides 42 and having an integral gear or rack 54 and the vertical Web 48 adjacent hopper end wall 49 has enlarged portions 55 for journaling a shaft 56 for the worm 51 which meshes with the gear 54 whereby the door may be oscillated in either direction to open, toeither dumping position, or to closed position.

An arcuate reinforcing flange 58 rigidifies the end of the door and protects the teeth of gear 54, and the ends of this flange are turned inwardly, as at 59, to form stops for abutting a lug 60 on the web 43 to limit the movement of the door. The lowermost portion of wall 49 is oflset, as indicated at 6!, to accommodate the end of the door similarly to the offsetting of projection 46 on the center transom. The stops 59 are spaced substantially sidewardly of the door side walls 42 so that the door will be in the full open position when either stop 58 engages the center stop 65 (See right hand side of Figure 3.)

By casting the door top plate, side plates, pivot bearings, and gear teeth as a unit, and by casting the hopper end wall 49, web 48, bearings 55 and lug 60 as a unit, the structure is simplified and made very rugged so as to adequately withstand the forces incident to the rough handling of heavy material which characterizes the use of cars of this type. As previously indicated, assembling and maintenance costs are minimized.

Figure 12 illustrates a modified structure in which the top plate 68 of the door corresponds to the top plate of the door shown in Figure 3, but the door side plates 69 merge with each other immediately below the door axis IE! and a downwardly projecting flange H forms a hopper extension deflector which serves to clear the rail, when the contents of the hopper are discharged, irrespective of the direction of the discharge.

Various other modifications and details of the 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.

What is claimed is:

1. In a hopper car, downwardly converging side walls, triangular shaped end walls extending therebetween, the lower portions of said end walls being ofiset outwardly of the hopper discharge opening, the upper elements of said oliset portions being arched between the sides of the discharge opening, and a door extending between said end walls and projecting into the offset portions thereof and having an arched formation fitting said elements and being arranged to tilt about the axis of the arched elements to either side of the discharge opening.

2. In a hopper car, hopper side walls with spaced apart lower edges defining a discharge opening, a door having a plate extending between said edges and mounted to tilt about a pivot paralleling said edges and below the same, and a web structure depending from said plate, said door being constructed to move said plate beneath either of said edges and to aline said depending web structure with the corresponding hopper side wall, said web structure extending below said pivot in either position of said plate to support the flow of the contents of the hopper during their discharge over and substantially beyond said pivot.

3. A hopper car door of the class described having an opening-closing top plate, side plates depending therefrom and a transverse end wall between said side plates, a series of gear teeth formed on said end wall and projecting laterally beyond the body of the door, there being a platelike lateral projection on said wall provided with an extension of said gear teeth, and a reinforcing flange extending across said wall and along said projections.

4. A hopper car door of the class described having a series of gear teeth formed on an end thereof, said gear teeth being arranged in an arcuate contour and being integral with and projecting beyond the end of the body of said door, there being a plate-like member extending from the side of said body and similarly projecting gear teeth thereon.

5. In a hopper car, a hopper having sides and ends and a discharge opening between said sides and ends, a door mounted to pivot about an axis extending parallel with and between said sides, a gear member on the end of said door and projecting therebeyond, a worm mounted on one of the ends of said hopper and engaging said gear member to hold said door in desired position and to move it to discharge position on either side of the hopper, a projection at the side of said door for supporting the end teeth of said gear, a reinforcing flange on said projection, a bracket on the hopper end which supports said worm, and a downward projection on the end of said reinforcing flange adapted to engage said bracket so as to form a stop to limit the movement of the door.

6. In a hopper car, a hopper having inclined sides and ends forming a discharge opening between them, and downward extensions on said ends for pivotally mounting an arcuate door, a stop on at least one of said extensions located above the pivot for said door and on a vertical line extending through said pivot, said door having gear teeth arranged arcuately on the end thereof, a flange on the end of said door below said gear teeth, and projections on each end of said flange for engaging said stop to limit the movement of said door when moving in either direction about its pivot.

7. In a hopper car, hopper structure with sloping side walls, door structure, means pivotally mounting said door structure on said hopper structure, said door structure comprising a part for closing the hopper opening, side walls depending from said part and extending substantially below said means, spaced stops on one of said structures, a stop on the other structure between said spaced stops, and means for rotating said door about its pivotal mounting, said stops cooperating to selectively position said door structure side walls in alinement with said hopper side walls to form extensions of the latter.

8. In a hopper car, hopper sides having a discharge opening between them, body structure extending transversely of said sides and comprising hopper end members and webs spaced therefrom, there being door pivot bearings on the lower portions of said webs and door stop elements on said webs above said bearings, a door having a top wall for closing said opening and end walls extending transversely of said top wall adjacent to said web, and an individual pin seated in each of said end walls and the corresponding bearings, there being a stop element on each of said end walls for engaging said stop elements on said webs.
