Serial No. 445,910.

This invention relates to improvements in car construction.

An object of this invention is to provide a simple and relatively inexpensive bracing construction for the free edge ofa floor sheet adjacent the hinged edge. of a discharge opening whereby said bracing construction will stifi'en the free edge of the hopper floor sheet, provide a rigid support for a discharge door and also operate as a tying member between the centersill and side walls of the car.

Another object of my invention is to provide an integral brace and hinge member which will maintain a hinged door in fixed relation to a hopper floor sheet throughout the entire range of movement of the door.

Still another object of my invention is to provide a combined floor sheet brace and hinge support which will cooperate with a hopper side Wall door sealing and reinforcing means to prevent sagging or distortion of said side wall.

My invention further resides in certain other details of construction such as is more fully pointed out hereinafter and claimed.

My improvements are shown as applied to a hopper dump car of the so-called W-type having hopper floor sheets and door parts,

' arranged to form hoppers at the lower portion of the car.

In dump cars of this character having sloping floor sheets disposed at an angle to each other, difficulty is sometimes experienced in maintaining a tight joint adjacent the hinged edge of the door, due to distortion of the free edge of the floor plate adjacent the hinged edge of the door and also due to corrosion followed by tearing of the material at the junction of the hopper side wall and floor plates. where the plates forming the hopper walls are generally bent from one plane to another.

My improved construction is designed to overcome the weaknesses of the above character by providing an integral bracing member along the free edge of the sloping floor plate at the hinged edge, of the door, said member extending from the center sill to the side wall of the hopper and formed with an integral flange or wall which overlies the side hopper wall and connects therewith and with a hopper side wall reinforcing and sealing member; said hinge member is provided with integral hinge lugs adapted to underlie a hinged door, the latter in turn being formed concentrically with respect to the pivotal axis of the door and forming a support for the overhanging portion of the floor plate in all positions of the door.

In the drawings forming a part of this 5 specification,

Fig. 1 is a vertical transverse sectional view taken through the lower portion of the car and showing slightly more than one-half the width thereof;

Fig. 2 is a side elevational view of that portion of the car illustrated in Fig. 1;

Fig. 3 is a sectional view taken on a line riprresponding substantially to a line 3-3 of Fig. 4 is a perspective view of the combined brace and hinge butt member;

Fig. 5 is a view showing a modified form of construction; and

Fig. 6 is a sectional view showing another modification of the hinge brace member incorporating an integral portion of the hinge butt to overlie the curved upper portion of the door.

Referring firstto the embodiment shown in Figs. 1 to 4, inclusive, wherein my improvements are shown as applied to a car of the W-type having vertically suspended doors: 10 indicates the centersill channels having a cover plate 11 and spacing members 12, said centersill being surmounted by an A shaped ridge 13. The vertical side wall of the car is indicated at 14. Intermediate the centersill and side walls of the car there are disposed on each side of the centersill a series of hoppers, but inasmuch as the construction on each side of the centersill and for-each hopper is of the same general character, the description herein will be confined to one said ho per.

ach said hopper includes a transversely disposed lon itudinally sloping lower bottom sheet 15 an inner and outer side walls 16 and 17, respectively. The inner wall is disposed substantially in a vertical plane and 100 said outer wall slopes downwardly and inwardly towards the centersill of the car. The hopper side walls are flanged as indicated at 18 and secured to the transversely extending bottom sheets 15.

Adjacent the upper portion of the hopper there is a transversely extending ridge shaped structure connected to the side wall of the car through the medium of gussets 19. This ridge shaped structure includes a longitudinally sloping upper floor sheet 20, the free edge of which, in combination with the side hopper walls 16 and 17 and sloping bottom sheet 15, defines a discharge opening through which the lading in the hoppers may be unloaded.

Positioned in the discharge opening is a dumping door A which is pivotally mounted on a combined reinforcing brace and hinge member B. The door A extends slightly beyond the inner face of the hopper bottom and side walls for the purpose of providing a bearing between the door surface and the hopper walls, the inner side wall 16 of the hopper being deflected inwardly as at 21 thence outwardly to provide a shoulder 22 in engagement with the floor surfaces of the door. The outer hopper floor sheet 17 is reinforced on its outer surface with an overlying rigidifying member C of appreciable width and flanged outwardly as at 23 and 24, respectively, to present'a channel shaped section. The flange 24 is further flanged at substantially right angles to the door surfaces, as indicated at 25, and the flanges 24 and 25 c0- operate with the door to form a tight oint at the outer side edge of the door.

At its lower edge, the said member C is flanged beneath the bottom floor sheet, as indicated at 27, and riveted thereto by rivets 28 and 29. Overlying the said flange 27 and secured thereto by the rivets 29 is the reinforcing angle member 30 which extends from side to side of the 'car, and ties together the pair of transversely aligned hopper sections which are disposed on opposite sides of the centersills.

The combined reinforcing brace and hinge member B which is of rugged construction and preferably formed of cast metal, includes a body section formed of angularly related walls 31 and 32, braced relatively to each other by a series of bracing flanges 33. The body section is preferably disposed an appreciable distance away from the free edge of the hopper floor sheet 20, and its wall 31 underlies said floor sheet and is secured there to by rivets 34. Adjacent each side wall of the hopper, the said member B is formed with depressed portions 3535 adapted to seat beneath the flanges 18 of the respective inner and outer hopper walls 16 and 17. The wall 32 of the member B extends substantiall at right angles to its associated wall 31. (gutstanding from this wall 32, beneath the upper floor plate 20, is a plurality of integral hinge lugs 36, preferably arranged in pairs with an intervening space between the lugs of each pair for the purpose of receiving the door hinge straps, as will be hereinafter described. Rearwardly of each pair of hinge lugs there is disposed one of the bracing flanges 33 which operates to strengthen the hinge member at these points.

The reinforcing hinge member B, at its inner end, has a wall 37 arranged to lie against and be secured to the web of the adjoining centersill 10 by means of rivets 38. At its outer end the member B is formed with a wall 39 extending upwardly from the body ortion of the member and braced thereto y means of a rib 40. This rib is preferably in line with and forms substantially a con: tinuation of the depending wall 32. The wall 39 overlying both the outer hopper side Wall 17 and the rigidifying' sealing member C is secured to both the said members by rivets 41. The wall 39 is formed with an offset, as indicated at 42, for the purpose of enveloping the offset flanges 24 and 25 of the said rigidifying member C.

' The dumping door A includes a main body portion 43 which is preferably flanged along its edges, as indicated at 44, 45, 46 and 47, respectively, the latter being disposed at the rear edge of the door and connected with the main body portion 43 by an arcuate portion 48, said arcuate portionbeing formed concentrically with respect to the pivotal axis of the door and acting as a support for the overlying portion of the floor sheet 20. Riveted or otherwise secured to the door is a pair of hinge straps 49, each said hinge strap being disposed between a pair of the hinge lugs 36-36 on the hinge member B. Extending through the lugs 3636 and the hinge straps 49 are the pivot bolts 50. Adjacent the free edge of the door is a beam 51 which is preferably formed of Z-shaped section extending transversely across the pair of aligned doors, the inner flanges 45 of the doors being flared, as indicated at 52, at the intersection of the said flanges 45 and beam member 51.

The doors are adapted to be opened and closed by suitable door locking and operating mechanism, as indicated generally by the character D, said mechanism preferably including an operating shaft 53 pivotally mounted in bearings 54, the latter being rigidly secured to the centersill. The shaft 53 has associated therewith a crank-like member 55 connected with the door by means of a link member 56, the latter in turn being secured to the door by the adjusting bolt and nut members 59 and 60 respectively. The operating shaft is extended outwardly to the side of the car through suitable bearings and is provided with suitable locking and rotating means indicated generally by. the char acter D.

The dumping door A, when fully opened, moves to the position indicated by the dotted lines in Fig. 3. The arcuate portion 48 of the door during such movement is at all times tangent to the projecting portion of the floor plate and acts as a support for the said projecting portion, it being understood that the floor plate 20, having a certain degree of flexibility, will rest upon and be supported by said arcuate portion 48 of the door and thus form a tight joint at the hinged edge of the door throughout the entire range of movement of the door.

The overlying wall 39 of the hinge and bracing member B, extending, as it does, to the junction of the inwardly sloping hopper wall 17 and the bottom floor sheet 20 of the car, acts as a tying member at said junction. By reason of the connection of the inner end of the bracing member to the centersill, by means of wall 37, there is effected a tying connection between the outer hopper side wall and the centersill. The fact that the wall 39 overlies the rigidifying member C and is secured thereto adjacent the upper end thereof, operates to extend the stiflening influence of said wall 39 beyond the confines of the wall itself, inasmuch as the rigidifying member C is stiffened adjacent each of its side edges by the flanges 23, 24 and25, and extends downwardly to the lower portion of the hopper where it is secured to the lower part thereof by the lower flange 27. My improved construction, therefore, provides a strong reinforcing beam at the side of the hopper which is supported at one end through the flange 39 of the rigidifying member and at the opposite end by the flange 27, the latter being secured to the angular member and thereby tied from one hopper to the other .clear across the car. It will be understood that Where the hopper walls taper downwardly at an angle in the manner illustrated and described, the pressure of the load operates to force said walls outwardly to a greaterdegree than if said walls were disposed vertically. This arrangement of the bracing member B at the upperportion of the hopper extending across from the centersill to the side wall, and the provision of the member 30 extending clear across both hoppers, at their lower portions, in combination with the rigidifying member C, supported at its opposite ends by said respective upper and lower members, all results in a construction which firmly supports the inwardly inclined side wall at its upper and lower portions and resists outward bulging of the hopper walls.

In the modification shown in Figs. 5 and 6, 210 indicates the centersill construction; 211 the sloping hopper bottom sheet at the upper portion 0 the hopper; 212 the outer side wall of the hopper; 213 the rigidifying andsealing member on the outer side wall of the hopper; 214 the combined brace and hinge member having angularly related walls 215 and 216, the wall 215 being secured to the hopper bottom sheet 211 and the wall 216 depending at right angles to form a reinforcing rib. On the opposite side to flange 215, there is also disposed a wall 217 which extends beyond the bottom floor sheet 211. Associated with said walls 216 and 217 are integral hinge lugs 218 which support the dumping door 219, said door being mounted. on the hinge lugs by means of pivot pins 220. At the outer end the combined floor brace and hinge member is formed with the overlying wall 221 which is secured to the side sheet 212 by rivets 222, a portion of said wall being extended and sandwiched between said hopper wall 212 and an offset 22 i formed in the rigidifying and sealing member 213. In this construction it will be noted that the dumping door cooperates with the portion 217 of the floor brace. At its inner end, the member 214 is formed with a wall portion 225 whereby a connection is effected with the centersill structure.
