DUMP CAR Filed June 5, 1926 2 Sheets-Sheet INVENTOR WITNESSES permitting Patented May 6, 1930 UNITED STATES PATENT OFFlCE' v WILLIAM L. BURNER, OF KOPPEL, PENNSYLVANIA, ASSIQNOR, BY MESNE ASSIGN- MENTS, TO PRESSED STE EL CAR. COMPANY, OF PITTSBURGH, PENNSYLVANIA, A.

CORPORATION OF NEW Application filed June 5,

This invention relates to railway 1 dump cars of the tilting body type. having outwardly swinging sides or side doors for discharging lading substantially clear of'the track rails, and has for an object the provision of means for permitting the side or door .at one side of the car to open outwardly by gravity when the body is tilted in the dire 'tion of this door, and to close the door when the body is being righted and further, to maintain the door in its closed position when the body is tilted in the opposite direction.

Another object of the invention is to provide the tilting body of a dump car, hav ng a side wall or door at each side hinged at or near its lower edge andadapted to swing outwardly to open position, with means for i the door or side wall on the lowering side of the body to move by gravity to its open position, while a similar means at the opposite orrrising side of the car W11]. maintain the door or side wall on this rising side of the car closed.

These and other objects will be apparent from the following description.

Referring to the drawings in which like reference characters refer to like parts, Fig. 1 is an end elevational view of a car embodying the invention, the body be ng shown in its righted position and Fig. 2 is a like view showing the body tilted to one side to its dumping position.

Referring now in detail to the drawings the reference character 1 indicates a dump car body which may be of any suitable construction and which is tiltably'mounted on an underframe 2 which may also be'of any suitable construction. In the resent embodiment of the invention the be y is tiltable toward one side or the other, but it will be understood that the invention-may be embodied in a car in which the body is tiltahle toward one side only. The body 1 prefer; ably comprises a fioor 3, ends 4 and side walls or side doors 5 which sidewalls ordoors are hinged at or near their lower edges to the floor supporting framing of the body. These doors are adapted to swing outwardly and downwardly and when in Open position each DUMP can 1926. Serial No. 118,847.

provided with an outwardly curved surface 7, such surface being joined with a substantially flat surface 8 on the underside of the member 6. To this member 6 there is pivotally connected one, end portion of a member 9, the other end portion of such member being pivotally connected with the underframe. Each one of the doors is provided at both of its ends with downwardly depending arms 10,- each of which has mounted thereon a roller 11 which is ada ted tolcontact with the surfaces 7 and 8 o the member 6. When the body-is in it's righted position the rollers 11 are in engagement with the lower end portions of the surfaces 7 of the members 6 and thus hold the doors or sides in their closed or load retaining positions.

Assuming that the car body is being tilted to the left side from its righted position as} shown in Fig. 1 toward its tilted position as shown in Fig. 2, the operations of the mech-' anisms are as follows :As the body tilts toward the left. the links 9, on the left hand side of the body and at both ends of the door on this side of the body, will preventlthe members 6 to which they are connected from moving downwardly more'than a predetermined distance with the body. It will here be noted that in the car illustratedin the drawings the body tilts and moves sidewise and that the members 6 will move sidewise with the body and at the same time will move a short distance downwardly. The door on the left-hand side of the body moves downwardly with the body and when the body.

has moved a short distance relative to the members 6 the rollers 11 on thearms 10 which have been in engagement with the surfaces 7 will engage the surfaces 8, thus-permittin the top of the door to move outwardly an downwardly by gravity, until the body has been fully tilted. As the opposite side of the body rises in the tilting movement, the links 9. maintain the members 6 on this side of the body in their proper ositions so that- 11, being in engagement with the surface 8' of the members 6 at the lefthand side of the car and these members being held down by the links 9, will cause the door to move to its closed postion, andas the body reaches its righted position the rollers 11 will engage the surfaces 7 causing the door to be locked against outward movement until the body is again tiltedin the direction. As the opposite side of the body descends the rollers 11' on the arms 10 of the door on this side of the body remain in contact with the surfaces 7 of the members 6, thus this door is kept in its closed position duringthe tilting and righting'of thebody as just described. It will be understood that when the body is tilted toward the right hand side of the car the operations of the mechanisms are the-reverse of those just described.

,Having thus described the invention what I claim as new and desire to secure by Letters Patent is 1. Ina dump car, an underframe, a body tiltably mounted on said under-frame, a door hinged adjacent its lower edges to said body, said door in its closed position forming a side wall for said body, a downwardly depending arm on said door, a member pivotally mounted on the end wall of said body having snrfaces with which said arm cooperates to control the opening movement of said door when the body'is being tilted and; to close said door when said body is being riqhted, and means for maintaining said member in its proper position relative to said body.

2. In a dump car, an underfra'me, a body tiltably mounted on said 'unde'rframe, a door hinged to said body, said door in its closed position'forming a side wall for said body, a member pi'votally mounted on the end wall of said body, adapted to be engaged by said door to control said door throng-limit its opening and closing movement when said body is being tilted and righted and ma'i'ir tain said door in closed position when the body is' elevated.

3. In a dum car, anunderframo, a body tiltably mounted on said underframe, a door hinged to said body and'forming a side wall, therefor, member pivotally cbnnected with the end wall" of said body, said? member having a curved end sur fa ce, and an arm on said door adapted to engage said surface to. hold dumping body to said door closed when said body is in its righted position.

4. In a dump car, an underframe, a body tiltably mounted on said underframe, a door hinged to said body, a roller on said door below said hinge, a member pivotally connected with said body and having a surface adapted to be engaged by said roller to maintain said door in its closed position, and a surface on said member adapted to be engaged by said roller to control the opening movement of said door when the'body is being tilted.

5. In a dump car, an undert'rame a-b0dy tiltably mounted on said underframe, a hinged door for said body adapted to swing outwardly by gravity toward its open position when said body is being tilted and means for controlling the opening movement of said ddor, said means comprising. a member loose- 1y mounted on the end of said body, means for-maintainingsaid member in operative position and means on said door for loosely engaging said member.
