` RAILWAY HOPPER CAR l l v Filed June 5, 1929 @duidt/M0155' n Patented Apr. 29, 1930 UNITED STATES WILLIAM E. WINE, OF TOLEDO, OHIO I RAILWAY HOPPER CAR Application led June 3, 1929. Serial No. 368,081.

My invention relates to railway hopper cars and more particularly to the hopper construction and associated door frame.

A principal object of the invention is to provide a strong and rigid door frame which may` be economically manufactured and which is so formed that it may be associated with the hopper sheets in a manner to produce a hopper having a'large capacity. a

A primary feature of the invention consists in providing the door frame with a plurality of flanges adapted to be respectively secured to the inner and outer side sheets and inclined floor sheets of a hopper, the flange of the frame and the portion of the inner side sheet, which are secured together being disposed at an angle to the general plane of the said inner sheet.

Another feature of the invention resides in forming a door frame fora hopper car with a plurality of flanges adapted to be respectively' secured to each of the sheets defining the hopper, the portion of the inner` side sheet of the hopper to which the door frame is securedbeing bent inwardly.

Other and more specific features of the invention residing in advantageous forms and combinations and relations of parts will hereinafter appear and be pointed out in the claims.

In the drawings illustrating a preferred embodiment of the invention: Figure 1 is a fragmentary transverse sectional view of a railway hopper car embodying the invention.

Figure 2 is a sectional view taken' on -line 22, Figure 1. v

Figure 3 is an enlarged fragmentary sectional view taken on line 3 3, Figure 1.

. Figure 4 is an enlarged sectional view taken on line 4 4, Figure 1, illustrating only the door frame and outerside sheet of the hopper.

Referring more particularly to the drawings 1 indicates one of the center sills of the car and 2 one of the side sills thereof. The hopper of the car, generally designated by the reference numeral 3, is formed by inner and outer side sheets 4 and 5, respectively, and a floor or slope sheet 6. The outer side sheet 5 inclines downwardly and inwardly from the side sill 1 and is offset adjacent its upper edge so as to be conveniently attached by rivets 7 to the upwardly projecting leg 8 of the side sill. The main portion of the inner side sheet 4 is disposed in a substantially vertical plane and lies immediately adjacent the bottom flange 9 of the center sill 1. At its upper edge the side sheet projects inwardly toward the web 10 of the center sill and terminates in an upwardly projecting llange 11 secured to the latter by'rivets 12. The lower'edges of the inner and outer side sheets of the hopper are flanged inwardly as at 13 to underlie the iloor sheet 6 and are preferably secured thereto by any suitable means (not shown).

Secured to the outer edges of each of the hopper sheets is a door frame 14 which is preferably formed as an integral unit of cast steel. The door frame is trapezoidal inl A shape and is provided with a substantially rectangular opening 15 to permit the discharge of lading from the hopper. Projecting inwardly from its side and bottom edges the frame is provided with a plurality of flanges 16, 17 and 18 adapted to be respectively secured by rivets 19 to the inner and outer side sheets and the floor sheets of the hopper. Bordering the door opening the frame is formed with outwardly projecting sealing flanges 20 positioned so as to be in close proximity to corresponding inwardly projecting marginal flanges 21 formed on the door 22 which closes the opening. Above the door opening the fr ame is so formed that it may be readily secured by rivets 23 to a transversely extending inclined sheet 24 which projects upwardly from the frame and is secured at its opposite end to a car diaphragm (not shown). The door 22 is hingedly connected to the frame by straps 25 which cooperate with pins 26 carried by outwardly projecting hinge lugs 27 disposed above the door opening. Any suitable mechanism may l 'be employed for supporting the doorv in closed position such as a hook 28 which may be pivotally mounted upon the flange 17 of the frame for cooperating with an arm 29 rigidly secured to a door spreader 30 mounted upon the outer face of the door.

- Alongv its lower edgethe frame is preferably rigidi-fled by a downwardly projecting liiange 31 which extends for a slight distance along the respective side flanges 16 and 17 thereof. The sidev of the frame adjacent the center sil1` may be also advantageously reinforced by a laterally projecting rib or flange 32.

In order to produce a hopper having maximum capacity the,` inner side sheet 4 lthereof is a-rranged as close to the center sill construction of the car as conditions will permit. In

hopper constructions employing cast door frames it has heretofore'been the practice either to space the linner'side sheet from the silla substantial distance to permit the frame to be attached to the sheet or else to construct the inner side of the frame so that it conforms generally to the contour of the adjacent center sill.

a plurality of flanges respectively secured tov the hopper sheets, the flange of the frame secured to the inner side sheet being interposed between it and the car center sill yand being disposed in a. plane forming an angle with the general plane of the said inner sheet.

4. A door frame for railway hopper cars having a plurality of flanges adapted to be respectively secured to the inner and outer side sheets and the inclined iioorsheet of a hopper, the ange of the frame adaptedl to be secured to the inner side sheet of the hopperlb'eing bent outwardly and disposed in a plane forming an oblique angle with the general plane of the said side sheet. f

5. A door frame for railway hopper cars having a plurality of flanges adapted to be respectively secured to-the inner and outer side sheets and the inclined 'floor sheet of a hopper, -said frame being also provided with a plurality of door sealing flanges, the flange of the frame adapted to be secured to the in,- ner side sheet of the hopper andthe adjacent sealing flange being respectively disposed in substantially vertical angularly disposed planes.

In testimony whereof I aiiix my signature.

inwardly bent portion 33 of the inner sheet, y I* I being secured to the latter by the rivets 19. The flange 16 is preferably secured to th'e outer face of the innerside sheet,.being interposed between it and the adjacentcenter sill.

The foregoing construction results in the production of a hopper which, having regard for the limitations in dimensions imposed thereon by the car construction, has extremely l large capacity. i

I claim: f 1. In a. railway car, the combination with a hopper involving inner and outer side sheets and an inclined floor sheet, the outer marginal l edge of the inner side sheet being bent inwardly, a door frame having a plurality of flanges respectively secured to the hopper sheets, the flange of the framel cooperating with the inner side sheet being secured to the inwardly bent portion thereof, and a door for closingthe lading discharge opening del fined by the frame. y y

2. In a railway car, the combination with a hopper involving inner and outer side sheets and an'inclined floor sheet. a door frame secured to the outer edges of each of sid sheets, the portions of the frame and the inner side sheet which are secured together extending at an angle to the general plane of the said inner sheet, and a door for closing the ladingdischarge opening deined by the frame.

3. In' a railway car, the combination with a. hopper involving inner and outer side sheets and aninclined door sheet, the inner side
