' construction.

The present invent-ion will be illustrated and described in connection with the type of dump car known as a selective car. This type of car permits the selective dumping of lading between the tracks upon which the car is mounted or outside of said tracks. It will be understood, however, as the descrip tion proceeds that many features of the present invention are'applicable to other types of car, the features of sturdiness and ready applicability and removability being of more general application than to selective cars.

An object of the present invention is to provide a dump car construction which,

while retaining all the advantages of convenient operation of certain cars as now known and used, provides improved sturdiness and improved convenience in building and in repairing.

A further object is to provide dump car construction in which'the various parts are so arranged that they may be secured together to form a construction having improved sturdiness over prior constructions.

Further objects will appear as the description proceeds.

Figure 7 is a sectional view taken along the plane indicated by the arrows 7-7 of Figure 5; I t i i Figure 8 is a view adjacent to the side dumping means, on an enlarged scale, of another part of the construction shown in Figure 2; i

Figures 9 and 10 are views in side elevation and end elevation respectively of a detail of the construction, to wit, a transverse brace member, shown in Figure 8; and v Figure 11 is another .deta-ilofthe construction, to wit, a sloping side wall brace, shown inFigure 8. p

The numeral 1 indicates a railway dump car of the selective type. Said; car is provided with the side walls 2-2 and the end wall 3. Trucks are provided at each end of the car, which trucks are indicated diagrammatically by the wheels 4-4:. Mounted between the trucks is certain dumping mechanism indicated by the numeral 5. Part of the dump doors is shown broken away in Figure 1 in order to illustrate certain mechanism which is shown on larger scale in the other figures'of the drawing.

Mounted adjacent to the two sidewalls 2-2 of the car are the inwardly sloping walls 6-6. Extending longitudinally of the car are the center sills 7-7, each of which may consist of a structure having a channel portion 7 and an extra outwardly extending flange 7". Suitable means are provided for connecting the center sills 7-7 together. Above the center sills 7-7 is the cope member 8 for sheddin lading to the two sides of said center sills. bec'ured to the center sills 7-7 are the sloping walls 9-9 which extend downwardly and outwardly from said center sills. It will be seen that each sloping wall 6 with its corresponding sloping wall 9 provides part of a hopper member, which hopper member is adapted to be openedor closed b certain door mechanism which will be brie car are the cross bearerslO-lO, which cross bearers may be rivetedto the center sills at the center of the .car and to the side plates at the sides of the car.

Cooperating with each pair of the'sloping walls 6 and 9 is the swinging dump. door indicated by the numeral 11, which dump doors are pivoted to swing" about the axes 12-12, said axes 12-12 being located adjacent to the sloping Walls6-6 andbeingsu r' ported in a manner which will be more particularly referred to hereinafter. Each of the dump doors 11-11 comprisesa closure member or supplementary door 13 and an extension member 14, said closure member 13 being pivoted to the extension member "14 about axis 15. A longitudinally extending rod 16 operates certain links or other mecha nism to control the two dump doors 11--11,

having operative connection with said dump doors at points adjacent to the extremities of the extension members l t-14. The details of the construction for supporting the shaft 16 and the details of the link mechanism for operating said doors will be de scribed hereinafter. It will be sufficient to state at this point in the description that operat-ion of the shaft 16 will control swinging movements of the doors 1111 about the pivots 12-12, whereby material in the car may be dumped between the tracks upon which the car is operated. Each of the dump doors 11-11 is rovided with a strengthenin 'rib 17 extending in a plane transversely of the car. Said rib 17 may have a cross sectional d contour of an inverted truncated V and is mounted to have a swinging movement about the corresponding axis 12. The sloping walls 66 are provided at their lower extremities with Z-bars 18--18, which have cut away portions conforming to the contour of the corresponding ribs 17. Each of the sloping floors 9-9 has at its lower extremity a reinforcing angle 19, said angle and floor being cut away to receive said rib 17. The structure described rovides a very sturdy construction. The s oping walls 9-9 with their notches for receiving the wedge-shaped strengthening rib 17 insure a very rigid construction. The fact that the wedge-shaped strengthening ribs 17-17 fit within corre- 'sponding notches in the Z-bars 18-48 also adds to the rigidity of the structure. Inasmuch as the dump'doors 1111 are located below the cross bearers 1010,. said doors may be of considerable length longitudinally of the car. By reason of the extended doors. the danger is minimized that the escape of lading between spaced doors longitudinally.

of the car will cause flooding of the rails. To still further minimizefloodin", each of the doors may have vertical end walls to form a scoop.

As indicated above, each of-the closure members 13-13 may have a pivotal movement about a corresponding axis 15, by which movement side dumping outwardly maybe accomplished. Each of said closures 13 is controlled for side dumping by a chain or other flexible member 20, which may be connected to the closure 13 by means of the eye bolt 21 (Figure 8). The other end of each of said chains is connected to a longitudinally extending shaft 22, which shafts may be operated by any preferred means. The pitch line of the chain 20 should pass through the axis 12 of the corresponding dump door 11. By reason of this construction, swinging of the dump doors 11-11 for center dumping does not changethe relation of the closure 13 to the remainder of the dump door. This advantage follows as a result of the fact that, regardless of the swinging of a dump door 11 as a whole about the corresponding axis 12, there is no change in the holding effect of chain 20, inasmuch as said chain merely swings with the remainder of the door about the axis 12. r

Link mechanism for operating the dump tion 25 whose axis is coincident with the axis of rotation of the shaft 16. Mounted within the center sills 77 is the shaft supporting member 26 which comprises a loop, said loop being supported from the lower inner flanges of said center sills 77. Said shaft support 26 has a U-shaped conformation, preferably slightly greater in dimension at its upper portion than at its lower portion, for thepurpose of facilitating the insertion of the crank member 23. Located at the two extremities of the cylindrical portion 25 are the crank arms 27 and 28, which are provided with the flanges 29 and 30 respectively. Saidflanges 29 and 30 should be cut away in line with the arms 27 and 28 in order that said flanges may not interfere with the insertion of either of the crank arms 27 or 28 through the shaft support 26. By this construction the crank member 23 may be mounted from either side of the shaft support 26 after said shaft support has been riveted in place. r I

The crank arm 27 is connected to the left hand door 11 (Figure 3) through a series of links, and the crank arm 28 is connected to the right hand dump door 11 through a second series of links. The links referred to need not be described herein, inasmuch as they form no part of the present invention. It will be suflicient to state that rotation of the shaft 16 in one direction will result in the opening of the dump doors 11 for center dumping, and rotation in the opposite direction will result in the closing of said doors.

Figures 1, 5, 6 and 7 indicate the structure by means of which movement may be communicated to the shaft 16 for opening and closing the doors 11, as above mentioned. The numeral 31 indicates a shaft, which for convenience of manufacture may be square in cross section. Said shaft, as indicated in Figure 1, may be operatedby means of a lever 32, which lever may have a ratchet action if preferred; The transversely extending shaft lot;

31 extends through the webs of the center sills 77, holes 33-'33 being provided for that purpose (Figure 5). It is necessary, of course, to provide round journals for the turning movement of the shaft 31, and in order to provide such journals, bushings 34are mounted upon shaft 31, said bushings 34 being provided with square apertures for reception of the square shaft 31. A worm 35 is mounted on the shaft 31 between the bushings 34. A casting 38 forming a supporting means for the journals of shafts 16 and 31 may be riveted to the lower outside flanges of the sills 7-7, the inside flanges of said sills being cut away, as indicated by the numerals 3939 to permit the insertion of the upper portion of casting 38 between the webs of the sills 77. provided between said upper portion of casting 38 and the sills 7-7 in order to avoid the necessity of planing or machining the cut portions. As indicated in Figure 6, the lower portion of the casting 38 may be bifurcated, the two legs thereof being indicated by the numerals 4141. Thus it will be seen that this casting in side elevation has the general form of an inverted V. The casting 38 is provided. with upwardly extending flanges 41, through which the casting is riveted to the inner sides of the center sills 77, said rivets passing through the filler plates 40. At an intermediate point the legs are provided with horizontal flanges 42 through which the castings are riveted to the lower flanges of the center sill. These horizontal flanges 42 are so located that when the casting is secured to the lower flanges of the center sill the parts will be in proper position for the reception of the operating mechanism.

It will further be noted that the bearings for the shaft 31 are formed substantially at the apex of the inverted V casting, while the bearings for the shaft 16 are formed transversely thereto'nea-r the extremities of the legs. Said legs 4141 may be provided with bearing portions 4242, which are cylindrically apertured for receiving the bushings 4343. Each of said bushings 43 may be shouldered at one end, as indicated by the numeral 44, which shouldered portion may abut against the sides of a worm wheel 45, which worm wheel 45 is adapted to mesh with the worm 35. The bushings 4343 may have an axial aperture of square cross sectionfor reception of the square shaft 16. Cotter pins 45-45 may be provided for preventing relative axial movement between theshaft 16 and casting 38, bushings43-43 and worm wheel 45. lt will be noted that the bottom flanges of the sills 77 serve as ledges to locatethe casting 38. Moreover, by reason of the riveted relation between sills 7 7 and casting 38, the sills are reinforced against Filler plates 40 are volving a shaft for operating link mechanism for opening and closing dump doors such as the dump doors 1l11, trouble has been eX-' large leverage, to turn the shaft in the wrong direction, which action often has destructive results on the mechanism of the car. The present invention contemplates means whereby such destructive results are rendered impossible. The worm wheel is provided with a pair of abutments 46-46 on the side faces thereof ofl' set from the axis of said worm wheel, which abutments may be conveniently provided. by a pin inserted through the Worm wheel 45 and extending laterally from the two side faces thereof. Located in cooperative relationship with the abutment-s 46-46 of the worm wheel 45 are the shoulders 41-47, which extend inwardly from the two legs 4141 of the shaft support 38. The shaft 16 in common constructions will require something less than a complete revolution in turning from full closed to full open position, or from full open position to closed position. For this reason the abutment-s 46 46 and shoulders 4T 47 may be so designed as to limit the extent of rotation of the worm wheel 45 to the amount required for the open ing and closing movements of the dump doors. If a workman should attempt to turn the operating shaft 31 in the wrong directioneither for opening. or closing movement, such movement would be prevented by reason of and shoulders 4747, so that destructive forces cannot be applied in any such manner to the link mechanism for operating the doors 1111.

- Referring now to Figures 8, 9, 10 and 11, the details of the construction providing mounting and operating means for the dump doors will be described.

Front an inspection of Figure 8 it will be noted that the sloping floor 6 is provided with a vertically disposed portion 48 riveted to the side wallQ of the car. A plurality of stakes 49 are provided, and adjacent to one or more of said stakes on each side of the car is a bracing member 50, which may be termed a combined stake brace and shaft and hinge support. at oneof its ends to the lower end of the corresponding stake 4 9 and at its other end is riveted to the Z-bar 18 and the lower portion of the corresponding sloping wall 6. At its upper side said support 50 is riveted to the adjacent cross bearer 10. Also riveted to the support 50, Z-bar 18 and sloping wall 51 is riveted at a plurality of points to the sloplng wall 6 and has avhooked over portion 52 which'engages and is riveted to the web the engagement between abutments 4646 Said support 50 is riveted portion of the Z-bar 18, whereby to form a very rigid construction. The support for receiving the pivotal support 0 the corresponding dump door 11, whichmay be disposed between the legs of the member 50.

It will be noted that the present invention provides a dump car of sturdy construction, which may be assembled with a maximum of convenience and which provides a maximum of assurance against destruction by improper operation.
