INVENTORS fifi id a f Patented Aug. 11, 1953 RAILWAY GONDOLA CAR STRUCTURE William M. Sheehan, Philadelphia, Pa., and Frank K. Mitchell, Dobbs Ferry, N. Y.; said Sheehan assignor to General Steel Castings Corporation, Granite City, 111., a corporation of Delaware Application December 5, 1951, Serial No. 259,924
The invention relates to railway rolling stock and is particularly, but not exclusively, adapted for use in gondola cars which have end walls hinged near the car floor and lowered to rest on the floor when the car is to carry articles which project beyond the ends of the car.
Since such cars do not have their end walls permanently fixed to the car underframe and car sides, it has been diflicult to provide light weight rolled steel or cast steel framing structure strong enough to resist longitudinal thrusts of the lading against the end walls seated against the car end framing or to resist other forces which would spread the corner posts laterally.
When lading shifts longitudinally of the car against upright end walls, or when machinery for handling lading strikes the end wall or the rail at the top of the car side, forces are applied to the end walls and corner posts tending to bend or fracture the corner posts or other members of the car end framing.
The main object of the present invention is to construct the underframe, end framing, and side walls of cars of the class described so as to adequately resist the forces which have previously damaged the cars but without unduly increasing the weight of the framing. This object is largely attained by providing a generally hollow beam-like end sill and corner post structure, including portions against which the end wall abuts, comprising spaced webs with interconnecting bracing instead of having a simple open end sill and angular end posts with single webs for abutment by the end wall as used in previous rolled steel and cast steel structures.
Preferably, the main members of the framing structure are of cast metal and it is a further object of the invention to simplify the casting of the framing so as to reduce the costs of patterns and molds and the costs of pouring and handling the castings.
These and other detail objects are attained by the structure illustrated in the accompanying drawings, in which: I

Figure 2 is a top view and horizontal section of one end of the car underframe and end structure and is taken on the line 2-2 of Figure 3.
Figure 3 is a front elevation and vertical transverse section of the end structure and is taken on the line 33 of Figure 2 and shows a portion of the end wall.
Figure 4 is a vertical longitudinal section taken on the line 4-4 of Figure 3.
Figure 5 is a detail horizontal section taken on the line 55 of Figure 4. v I
Figures 6 and '7 are detail vertical longitudinal sections taken on the corresponding section lines of Figure 2.
Figure 8 is a detail vertical section on line 88 of Figure 1.
Figure 9 corresponds to Figure 2, but shows another form of the underframe and end structure.
Figure 10 is a front view and vertical transverse section of the end structure shown in Figure 9 and is taken on the line Ill-l0 of Figure 8.
The invention, as illustrated in Figures 1-8 embodies a one-piece underframe A with integral end structures B, each including an end sill C and corner post lower portions or bases D, to which separately formed corner posts E are applied. Each end sill C includes a striking plate I and a coupler carrier 2. The end sill has vertical webs 3 and 4 merging at the ends of the sill and onset inwardly of the ends to form a horizontal shoulder web 5. Web 3 increases in depth from the ends of the sill toward striking plate I and web 5 similarly increases in width. Web 4 is substantially uniform in depth throughout its length. A horizontal web 9 extends inwardly from the lower edge of web 3.
A horizontal floor supporting web or flange 8 is spaced from web 5 and isat the same level. Upstanding webs 4 and 6 extend along the adjacent parallel edges of webs 5 and 8 and a horizontal web 7 connects the upper edges of webs 4 and 6. Immediately over the coupler pocket P, webs 4 and 5 are interrupted or replaced by a forwardly and downwardly inclined web l0 merging with the outer edge of web 1 and the top edge of plate I. The horizontal flange 8 extends inwardly from the lower end of web 6 and varies in width as indicated in Figure 2. Elements 6 and 8 form an angular recess G exteriorly of the hollow sill to receive and seat the bottom edge of the car end wall F. Elements 6, 1, 8 form an upright 2 section from end to end of the end structure. Elements 4, 1, 6 form an inverted U section from each end of the end structure to, the striking plate and abreast of the striking plate one leg of the U section is inclined as at H).
At each end of the end sill, web 1 turns upwardly to form the inner side wall I l of a corner post base D; inner upright web 6 extends upwardly to form the inner end wall l6 of the post base; upright web 4 extends upwardly to form the outer endwall M of the post base; lower web .9
extends upwardly to form the outer side wall IQ of the post base; and flange 8 extends upwardly to form an intermediate side wall I8 for the post base and a gusset-like member for attaching the separately formed car side wall plate 26. Elements l4, l6, l.'|,. l8, l8.merge to form a box section which, with the large radius curvature between webs and I1 and the wide end portion 8a of flange 8 and with the wide gusset l8, provides a strong, rugged corner structure which will not be broken by any force likely to be applied to it.
The lower ends of each corner post E are ofiset inwardly and are received within the corresponding walls of base D. Corner posts E are welded .to bases D as indicated at W. and I8 and the corresponding elements of each post E form an upward continuation of the angular seat G for the car end wall. End wall F may be held in upright position and against its seat in the end sill and" corner posts by simple latches H (Figures '2, 3). 'By unfastening latches H the .end wall may be swung to horizontal position resting upon the car floor. The web of each corner post E extending upwardly from base web I8 extends rearwardly of the corner post box section, as indicated at 20, and is recessed at 2| to receive the car side wall plate 26, which is welded to the post throughout itsheight and forms a tie'between the corner post, the corner post base and the adjacent portions of the underframe side sill 23.
The invention .as illustrated in Figures 9 and 10 embodies an underframe'with structural steel sills 30, sidesills 3!, intermediate sills 32 and bolsters 33. Side wall plates 34 and stakes 35 are mounted on the underframe as indicated in Figure 1. Secured to each end of the underframe is an end structure including an end sill K, buffer block '36 and coupler carrier 31, aspreviously described, but the ends of the end sill extend upwardly to form the entire corner posts 38 instead of post bases only.
The end structure includes inwardly extending projections 40, 4! and 42 for connection to the ends of sills 30, 3| and 32. .Each' end structure is a single one-piece casting and, preferably, is welded to the structural underframe-sills as indicated at W. The draftgear stops 43 which takes the draft gear forces are all on the center sills rearwardly of welds W so that these forces do not pass through the welds. The sill projections 4| include gusset-like elements 44 to'which the side plates 34 may be secured to better reinforce the corner construction.
Asingle underframe casting embodying longitudinal sills, main bolsters and intermediate transoms may be utilized in place of the structural steel underframe shown in Figuresfi and 7 and the separately cast end structures may be welded to the underframe casting. 'With such construction the entire underframe and end framing would consist of three castings welded into a rigid unit.
In each form of .the invention the cast metal unit is relatively shallow; thus avoiding-deep patterns and flasks'and the resulting expense of molding and casting the framing as would be the case if the complete posts and underframe sills were made in one piece.
In each form of the invention the hollow beamlike end sill and the box section corner post arrangement, whether the entire posts are integral with the end sill or are separately formed, comprises a rigid corner construction well adapted to resist the forces to which-it may be subjected "Post base elements .I 6
