HOPPER-DUMP-CAR CONSTRUCTION.

Specification of LettersI Patent.

Patented Apr. 15,1919.

To all 'whom t may con-cern Be it known that L'HARRY S. HART, a citizen of Athe United States, residing at Chicago, in the 'county of Cook and State of Illinois, have invented certain'new and useful' Improvements in Hopper-Dump-Car Constructions, of which the following is a specification.

This invention relates tp dump cars.

The object of this invention is to simplify and improve dump. car constructions in a novel manner to increase the capacity thereof and at the same time retain the self-cleaning feature.

' tion;

This and other objects are accomplished by means of the arrangement disclosed by the accompanying sheets of drawings, in which- Y 4 Figure 1 is a fragmentary side elevation of a railway dump car embodying my inven- .F ig. 2 is a fragmentary plan View of the same car;

I endo i verse center line of the car, itis found that and,

trucks.

Fig. 3 is a transverse sectional view of the same dump car taken over one of the trucks;

Fig. 4 isa transverse sectional view ofthe same ear taken between the trucks.

It isa well recognized fact that it is of vital importance to increase the carrying capacity of railway cars, and especially,

the capacity can be effectively increased by changing the floor construction over the Referring to the figures of the drawings, it will be noted that Ihave shown a dump car including sides 10, ends 1l and a floor, the floor portions over the trucks being of A-shaped construction in which the apex l2 of the A is located over the center sill 13, the

sloping members 14 of the A-shaped portion extending downwardly and outwardly to- Award the sides vot' the car. These sloping floor members 14: preferably are stationary and connected to the under frame to thereby increase the stiffness and rigidity-of the car structure. The discharge openings at the lower ends of the floor portions lit normally are closed by side dump doors 15 which preferably are pivotally connected at 16 along the lower edges of the sides lO of the car, the swinging edges of the doors 15 when in closed position forming a tight seal Withithe lower edges of the floor members 14. The dump doors 15 may be provided with any suitable operating mechanism including operating shafts 17,-preferably carried by the doors 15 and also chains 18, which' connect the shafts with the stationary floor portions 14. s

The floor intermediate the trucks is at a lower level thanthe ioor portions over the trucks and includes a plurality of transversely arranged hoppers 19 formed by transversely extending shedding members 20, there being transversely arranged hoppers 19 on both sides of the longitudinal center of the car, the longitudinal division of the car being formed. by shedding means 21. Each of the transversely arranged hoppers 19 hasits ioor portion composed 1n part by a plurality of doors 22 hinged transversely of the car and swinging toward and from each other to. closed and opened positions, respectively. Leading from the extreme doors 22 nearest the ends of the car are sloping ioor members 23 which extend to the apex 12 of the loor portions over the trucks. In cars heretofore built the sloping floor portion ,23 is continued in the same plane to the end 11 of the car. It is apparent, therefore, thatby providing the floor construction over the trucks, as shown -in this application, the carrying capacity of the dump car is greatly increased and at the same time the selfcleaning teature is re tained. When the side dump doors 15 are opened, it will be appreciated that all of the dumpable material over'the trucks will be discharged to either side of the car, and when the transversely arranged dump doo-rs 22 are opened, the remainin dumpable material in the car will be discarged intermediate the trucks, all of the ioor portions being slanting or movable in a manner .such that the car will completely discharge its load upon opening of the doors. The transversely arranged dump doors may be pro- I vided with any nism 24 from each other to closed and' openedpositions, respectively.
