CAR CONSTRUCTION.

Application filed May a0, 1926. Serial No. 110,392.

My invention relates to improvements in car construction and more especially to an improved car side construction for hopper cars and the like.

It is anobject of my invention to improve the construction of a car having hoppers below the side walls, whereby the lower margins of the sides will be inwardly offset, and suitably rigidified and braced to form supporting means for said hoppers.

It is also an object of my invention to provide suitable construction whereby a car having inwardly offset sides extending only between body bolsters, may be suitably connected in an effective manner with the end sills of the car, and continuity of reinforcementaflorded between the end sills of the car.

It is also a further object of the invention to adapt an offset side construction to perform the function of a load carrying chord and to brace the same against bulging and buckling and protect the parts entering into the construction thereof against corrosion.'

Other objects and advantages of the invention will be more clearly pointed out herein- 7 Referring to the drawings, Fig. 1 is a side elevational viewof a portion of a hopper car embodying my improvements, a portion of the side wall at the left of the figure being broken away to better illustrate the cross beam construction. Fig. 2 is a broken horizontal sectional view, illustrating the sidewall and adjoining construction, said section being taken on a linecorresponding substan- Fig. 3 is an enlarged fractional sectional plan view of a ortion of the car taken ad'acent the outer end of the bolster, and on a ine corresponding substantially-to line 3-3 of Fig. 1, said view illustrating the connection between the main side wall and adjacent brace which extends from the bolster to the end sill of the car. Fig. 4 is an enlarged fractional transverse sectional view taken throu h the lower portion of the car side wall and opper on a line corresponding substantially to line 4-4 of Fig. 1. Fig. 5Iis an enlarged fractional transverse sectional view, somewhat similar to Fig. 4, except that the section includes one of the side stakes, said view being taken on a line corresponding substantially to line 55'of Fig. 1. Fig. 6 is an enlarged transverse sectional view showing approximately one of the cross-members of the car, F the end Slll of the car, G one of the side braces extending from bolster to end sill, H one of the connecting gussets between the main side wall and adjacent side brace, and J one of the discharge hoppers disposed below. the

' side wall and 'center sill of the car. Only one end portion of the car is shown, it being understood that both ends of the car are of similar construction, and the number of cross-members and hoppers intermediate the body bolsters will vary depending on the len th and construction of the car.

he side walls A are spaced outwardly for the major portion of the length of the car to substantially the maximum allowable road clearances, in order to gain increased carrying capacity between the side walls of the car. The side walls A are each formed of a plate 10 having a vertically extending main portion and an inwardly and downwardly bent flange 11 at the lower margin thereof, for a purpose aswill be hereinafter fully pointed out. The upper margin of the car side is provided adjacent the top with a suitable rigidifying member 12, which is secured to the top margin of the plate 10, the platev 10 at the top of the car side being bent inwardly as indicated at 13 to dispose said rigidifying member 12 within the'car side clearances. Adjacent the end of thg car a portion of the side wall of he car as indicated at 14 is disposed inwardly of the main plane of the said car sidewall thereby presenting narrowed body portions at the ends of the car. The transition from the planes of the respective walls is effected byan angularly related wall section as indicated at 15. In the re cesses thus presentedby the narrowed end body portions there are disposed a series of ladder treads 16.

Secured tothe inwardly and downwardly inclined flange '11 of the car side plate 10 is a rigidifying member 17 which is pref:

erably in 'the form of a flanged member with one of its flanges 18 overlying the said flange 11 and extendingin the same general direction, and having its adjacent flange 19 outstanding from the said first named flange, the member 18 extending longitudinally of the car between the body bolsters D, and being directly secured thereto and to the respective cross members E by means of rivets extending through the flange 18 and the outer ends of the respective cross members.

The cross members E of the car include transverse vertical wall members 20 which extend between the respective side walls and center sills of the car as shown in Fig. 6, only one half of the car being shown in said figure, but it will be understood that the construction is similar on both sides of the center sill. 1

Connection between the side wall 10 of the car and the plate member 20 is effected by an integral flange 22 formed on one side of the plate, and aseparate angle shaped member 23 on the opposite side of said plate, the said member 23 being also bent adjacent its lower portion, and extended over the inwardlyv directed lower margin of the car side and secured ,thereto by a series of rivets. Connection between the transverse plate 20 and center sill C is also effected by an integral flange 24 on one side of the plate and a separate angle connection 25 on the opposite side thereof.

The transverse plates 20 on the opposite sides-of the center sill C are tied across The plane of the center sill by an angle shaped tie member 26, and by inclined shedding plates 27-27,' said last named plates together forming a transverse load shedding ridge sloping longitudinally of the car. The lower margin of each plate 20 of the cross member E is rigidified by an angle shaped member 28, said member at its outer end being bent upwardly at 29, to overlap the inwardly directed portion of the car side. The said angle shaped member 28 is disposed on the side of plate 20 opposite to the vertical angle member 23, and said members overlap and are united together and to the plate 20 by means of rivets 129, thereby forming aT construction of great strength.

The crossbeam sections 2020 are also tied h a lower plate 30 extending across the plane of the center sill. The inwardly directed portion of the car side is also tied to the crossbeam 20 by a gusset plate 31-, which is secured to the outstanding marginal flange 19 of the rigidifyin member 17, and to the horizontal flange o the angle member 28. The respective flanges 18 and 19 of the angular member 17 are braced at suitable intervals by bracket members 32 which are riveted to the respective, flanges thereof.

The heavy angular shaped members 17 are preferably adapted to extend only between the body bolsters D, being connected to the outer end thereof, as shown in Figs. 3 and 7. Each bolster D includes a vertical web plate 33 having lower marginal angle shaped reinforcements 34 and 35 along the bottom edge thereof, said angles being bent upwardly as indicated at 134 and 135, to conform to the shape of the car side, and adjacent the Quter end of the car side there are vertically extending inner and outer angles as indicated at 36 and 37 respectively, said last named members being connected to the vertically extending portion of the car side wall. The angles 36 and 37 are also extended downwardly, and bent as indicated at 136 and 137 respectively to conform to the shape of the inwardly directed portion of the car side. The downwardly bent portions 136 and 137 of the members 36 and 37 overlap the upwardly bent portions 134 and 135 of the members 34 and 35, and the overlapping portions are rigidly united to each other and to the web plate 33 by a rivet'38. The overlapping portions of the angle members thus provide continuous lateral flanges along the edges of the'web plate 33 of the bolster.

Connection between the angle member 17, and the bolster, is effected by riveting flange 18 to the lateral flanges of the bolster where they are overlapped, and also by riveting the outstanding flange 19, of the angle member 17 to the bolster cover plate 39, which is formed to project on opposite sides of the lateral flanges on the bolster, and extended outwardly beneath the said outstanding flange 19. A jacking plate 40 is disposed beneath the end of the bolster and outstanding flange 19 of the angle member 17.

The angular member 17 is further secured to the car side adjacent the bolster through the medium of gusset member H which forms a connectionbetween the end brace G, and the vertical car wall section. The gusset member H is formed with portions extending respectively above and below the brace, the upper portion being'disposed between the vertical car side wall, and the outer vertical bolster connecting angle 37, while the lower extension isv bent inwardly to underlie fiange-18 of the vertical member 17 and is secured thereto by rivets 41, said underlying portion of the gussetmember being in the same plane as the inwardly bent flange 11 of the car side wall, a section of the said gusset being out out as indicated at 139 and 140 to clear the flange 11.

Each brace G is extended to the end sill of theicar, and suitably connected therewith at thecorner post 42 in the'usual manner.

The length of the end sill coincides suband each end brace G is deflected inwardly as indicated at 43, to permit of the attachment of the respective ends to portions of the car in different vertical planes.

Extending transversely of the car above the body bolster is the sloping floor 44 which lower slopes longitudinally of the car towards the center thereof to the lowerhopper J, said floor terminating at a discharge opening 45 which is adapted to be closed by a transversely extending door 46. A longitudinally extending side floor sheet 47 is secured to the car side and sloping floor sheet 44, thereby forming with the dumping door 46 the hopper section J. The side 'floor sheet 47, as best illustrated in Fig. 4 is bent to present a vertical section 48 for attachment to the vertical side wall sheet, and is then bent to slope downwardly and inwardly asat 49 to present a shedding plane overlying the angular member 17, and thereafter it is bent downwardly at a steep angle and extended below the side of the car to form the main side wall of the hopper section J. The said floor sheet 47 extends longitudinally of the car from the cross member shedding plate 27 to the sloping floor 44, thereby presenting an efiicient sealing member to close the joints between the main side wall sheet and the lower angular member to prevent seepage of water and moisture between the joints, and it thus retards corrosion of the parts.

The sloping section 49 of the side hopper sheet is secured directly to the flange 18 of the member 17, as indicated at 50, and also by rivets 51 extendin throu h the section 49, the member 17, an the underlying flange 11 of the side wall. The side floor sheet 47 is flanged as indicated at 52 and 53, which flanges respectively are secured to the sloping floor sheets 27 and 44.

At certain intervals in the length of the car side wall vertical braces as indicated at 54 and 55 are disposed on the inner side of the car wall, said members being extended downwardly over the sloping portion of the side wall and riveted thereto as at 56, said construction being best indicated in Fig. 5. i

It will thus be seen that my invention provides a strong construction which forms an adequate support for the lower hopper sections and rovides for continuity of reinforcement in the car side wall between the ends of the car, whereby bufling shocks may be efl'ectively transmitted without buckling or bulging the side walls. The disposition of the outstanding rigidifying flange in the lower chord of the car side immediately at the junction of the sloping car side and the hopper J, and the tying of the said flange to the cross members by gusset plates ensures a very rigid construction against bulging of the car'sides. The formation of the car side and disposition of the lower chord member to conform to the load containing capacity of the car provides for maximum carrying capacity and the novel arrangement of the car side and side hopper floor sheet effectively protects the said lower the combination with a side wall.
