DUMP-CAR CONSTRUCTION.

Application mea November 14, i923. serial No. 674,606.

, two ends of the car. If the lading to be depo'sited is relatively heavy, such, for exampel, as rock ballast, the carrying capacity for such lading is limited not by the bulk thereof but by the weight. Ballast cars in common use limit the amount of rock ballast orother heavy ballast to that which may be carried by said car at regions from which dumping may be conveniently accomplished between the trucks. When it is desired to carry other lading such as coal,

which is lighter in weight, certain types of ballast cars are quite inefcient inasmuch as they do not economically utilize the space over the trucks.

An object of the present invention is to provide an eiiicient car for carrying heavy lading such as rock ballast which should be deposited selectively between the rails or outside of the rails and for carrying lighter lading such as coal which need not be dumped between the rails.

A further object is to provide a car' utilizing materials which are no heavier than ordinarily provided in car construction which will operate efficiently as a ballast car for depositing ballast either between the rails or outside of the rails and will present a maximum capacity for lighter lading.-

A further object is to provide a dump car .conforming to standard practice which will at the two ends of the car l are illustrated diagrammatically by the wheels thereof which are indicated by the reference numerals 4.-4. According to the illustrated embodiment of the present invention the car 1 is provided with dumping mechanism located between the trucks, said dumping mechanism comprising doors 5 5 which are mounted for swinging movement about axes disposed longitudinally of the car. Referring to Figure l, a shaft 6 is provided carrying chains 7 7 for operating the doors 5 5. The details of construction of the dumping mechanism between the trucks need not be described herein inasmuch as such `details are well known to those skilled in the art and inasmuch as such details form no part of the present invention.

Adjacent to each end of the car is a floor 8, which floors slope toward the adjacent ends of the doors 5 5. That is to say, said floors 8 are so sloped that lading located above said floors will tend to move toward the doors 5 5 when said doors are opened.

VSaid floors 8 8 should be disposed at such an angle relative to a horizontal plane that such lading as rock ballast will flow therefrom. 'Ihat' is to say, the' angle should be such that the force of gravity acting upon rock ballast located above said floors will be suliicient to overcome the resistance to flow due to Contact between said floors 8 8 and the ballast resting thereon. For this purpose it has been found by experiment that the angularity of the floors 8 8 rela'- tive to a horizontal plane may be approximately 45 when the car is designed for the carrying of rock ballast.

At each end of the car above the trucks is a lloor, indicated bythe numeral `9. According to the embodiment illustrated in Figure 2, each of the floors 9 may comprise sloping portions for directing lading laterally of the car, said sloping portions having their apex along the line marked by the angle 10.l Swinging side doors 11 1l may be provided, controlled in any ,preferred way, for permitting lading to flow from said floors 9 to the sides of the car.

Each sloping floor 8 extends to a line disposed transversely of the car,4 which line lies above the corresponding truck illustrated by wheels 4 4. Cooperating with each slopin-g lioor 8 is the reversely sloping floor 12, each pair of said sloping floors 8 and l2 having their apexkprotected by the angle: 13.

Thus the apex of the sloping floors 8 and 12 at each end of the car is between the bolsters 13. This location of the apex makes it possible to provide sloping ioors which will be at the proper angle for eliciciently discharging the load either through the end dumping portions of the car, or through the center dumping portions. The sloping floor 12 at each end of the car will direct lading disposed above said sloping i'ioor 12 toward the corresponding floor 9 and doors 11-11 whereby lading at the ends of the car may be discharged through said doors 11-11 laterally of the car. It will be obvious that the angle 13 and sloping floors 8 and 12 at each end of the car will form shedding means for directing lading either to a region between the trucks to be dumped by the doors 5 5 or to a region over the trucks to be dumped by the doors 11 `11. Described in other language, it may be stated that each of the floors 9 is a longitudinally extending A-shaped floor having its apex extending inwardly, along a medial plane of said car, from the ends of said car to a point beyond the adjacent bolster 13; that is to say, the apexes oi' said A-shaped lioors extend to points between said bolsters. The iioors 8 and 12 at each end of the car also provide A-shaped floors extending transversely of the car between the dumping mechanism 5 and the longitudinally extending lioors 9. The transversely extending ioor at each end of the car and its corresponding longitudinally extending floor form a T-construction, the head of which `T-construction lies between the bolsters 13. The construction described and illustrated increases the capacity of a dump car a material amount over prior practice.

In operation, when it is desired to use the car for carrying rock ballast or other heavy lading, said heavy lading will be deposited in the car centrally thereof, being carried by the bottom portion between the trucks and by the sloping floors 8 8. According to the illustrated embodiment of the present invention the limit of such heavy lading longitudinally of the car will be marked by the angles 13 13 located over the trucks. Said heavy lading may assume an angle otl repose illustrated by the dashed line 14. It

'will be clear, however, that it it is desired to carry lading all of which is to be directed vbetween the trucks, the capacity for such tween the sloping walls 8 and 12 being unused at this time.

By reason of the present construction a railway dump car is provided which has a maximum carrying capacity for light weight lading' and sacrifices none of the advantages attached to the ordinary type of selective dump car.

Though a preferred embodiment has been described in detail, many modifications will occur to those skilled in the art. It is intended in this patent to cover all such modivfications that fall within the scope of the invention as defined by the appended claims.
