Be it known that I, DAVID HINDAHL, a citizen of the United States, residing at Ghicagoin the county of Cook and State of Illinois, have invented certain new and useful Improvements in Maximum-Capacity Cars, of which the following is 'aspeciiication. The present invention relates to maximum capacity cars. I t

More particularly the present invention relates to the construction of railway dump cars. Cars of this sort are commonly designed to deposit lading selectively outside l5 of the tracks or between the tracks between the trucks, which trucks are located adjacent to the two ends of the cars. If the lading to be depositedl is relatively heavy, such, for example, as rock ballast, the carrying capacity vfor such lading is limited not by the bulk thereof but by the weight. Ballastcars in common use limit the amount of rock ballast or other heavy ballast to that `which may be carried by said car at regions from which dumping may be vconveniently accomplished between the trucks. Inasmuch as the distance betweenthe trucks is limit-ed by certain specifications, a problem which has presented itself to designers of cars of this sort has been to so design the parts that a maximum of ballast upr to Vthe limit of weight may be carried without sacrificing the advantages ofconvenient dumping and without sacrificing adaptability for the car for carrying lighter lading. KVCertain*types of ballast cars which have been designed are quite inefficient when it isdesired tocarry other lading such as coal, which is lighter in weight, inasmuch as said cars do not economically utilize the space over trucks.

the

The present invention relates'to the sameV car for` carrying a maximum ofjheavy lading, such as rock ballast, which should be 1924. Serial No. 723,861.

deposited selectively between the rails or outside of said rails and for carrying lading such as coal, which need not be dumped between the rails.

Further objects will appear as the description proceeds.

Referring to the drawingsp Figure l is a longitudinal sectional view of a railway dump car embodying the principles of the present invention; and Figure 2 is a transverse sectional view taken along the plane indicated by the line 2 2 of Figurev The numeralv l indicates a dump car liaving the sidewalls 2-2 and end walls, one of which is indicated by the numeral 3.

Trucks, one of which is located adjacent to each end of the car, are illustrated diagrammatically by the wheels thereof, which wheels are indicated by the numerals 4-4. According to the illustrated embodiment of the present invention, the car is provided with dumpingmechanism located between the trucks, said dumping mechanism comprising doors, one of which is indicated in part of its length in Figure l, said door bearing the numeral 5. Said doors 5 are mounted for swinging movement about axes disposed longitu-dinally of the car. Y

The mechanismgand arrangement of the dump doors between the trucksneed not be illustrated or described, inasmuch as dump-V ing mechanism for the purpose is well known. It will -be` sullicient to state that the dumping mechanism between trucks will preferably permit the selective dumping either between the rails upon which the car is mounted or outside of said rails.

Each end of the car is provided with a 'sloping floor 6, which floors 6 slope toward the adjacent ends of the doors 5, that is to say, said floors 6 6 are so sloped that lading' located abovel said floors will tend to move toward said doors 5 when said doors are opened. Said floors should be dispos-ed at such an angle relative to a Yhorizontal plane that such lading as rock ballast will flow therefrom, that isV to say, the angleV should be such that the force of gravity acting upon rock ballast located above said `floors will besufficient to overcome the resistance to flow due to Contact between the floors 6-6 and the ballast resting thereon.

For this purpose it has been found by eX- periment thatthe angularity of the floors 6 6 relative to a horizontal plane may be approximately'l' degrees with the car standing upon a horizontal track, in case said car is intended for the carrying of rock ballast.

nt each end of the car above the trucks is a floor indicated by the numeral 7. rlfhe details of construction of the floors T'do not form a part of the presentinvention, but said floors should be so designed as to permit the discharge of lading therefrom tothe sides of the car outside of the rails. Any preferred design of floor may be used, many of such designs being lnown tothosen skilled in the art. According to the illustrated 'embodiment of the present invention, thef'floors 7 may comprise sloping!portionsfor directing lading laterally ofthe car, said sloping portions having their apex alongthe line marked by the angle 8. I Swinging vside doors 9 9 may be provided, controlled ina-'ny preferred way, forpermitting ladingto Ylow from said floors 7 to the sides of the car.

Cooperatingwit-h each sloping floor 6 is thereversely sloping floor or -wall 10, which floors 10 10-are:provided for the purpose of supporting-lighter lading at the ends of the car. Each sloping floor 6 extends to al line disposedtransverselyv of the cai-,which line lies near'the top ofthe ca'r above the Correspendingv truckindicated by the wheels 4 11. In the illustrated embodiment of the presentinvention the top of each 'floor 6 lies ina vertical plane substantially midway between the wheels/1 4 of its adjacent truck. rlhe'upper edge of each lioor 6 will be provided with'an angle 11,-/one flange of whichunderlies the corresponding floor 6 and the other lian-geof whichv extendsupwardly toward the vertical transverse centralplane ofthe car. Saidang-lesg11 11 deline the limits, longitudinally of the car, of the lading carried centrally-of said car, the outline of which lading is indicated by the numeral 12.

The numeral 13 indicates a bolster eom prising -the twochannels 13 1i3-. Said bolster ismade use 'of insupporting the corresponding sloping lioorlO. Mounted above. and below said bolster 13 are the transversely extending steel vplates 11i and 14X, the upper of which carries the transversely extending steel angular memberl. Said angular member lhas `a portion engaging with the steel plate 111, preferably riveted to said plate and to the bolster 13,and another portion extending in ythe direction of the floor 10. Rivetedto eaclrfioor 10 and to the corresponding angular member 15 "is the plate 16, which has a portion 1'6a lying in a plane parallel toand adjaeentto the plane'of the corresponding floor`1'0. Each plate 16 also has a portion 16b lying in a vertical plane, having edges conforming to the floors 7 7 and to the side doors 9 9.

Said angular member 15 a-ndplate 16 effectually prevent the zlold-gment of'lading in the space between the floor 10 and the fioor 6. Each sloping floor 10 is secured to the corresponding slopingfloor 46 by'ineans of anangle 17, which may be riveted to said floors. l Underlying each of the sloping lioors 10 are braces 19, which may convenientlytake the form of angles riveted to the corresponding floors 10. Said angles may be bent at their lower ends, as indicated by the numeral 20, and may be riveted to the corresponding angularlmember 15, the corresponding plate 16 and correspond ing floor 10. e

ln operation, when it is desired to use the car for carryingrockballa'st orv other heavy lading, said heavy lading will be deposited in the car eentrally thereof, being carried by the bottom portion between the trucks and i by the sloping lloors 6 6, said heavy lading assu-ming van angle of repose, which may be indicated by the broken line12. The angles 11 11 at the Vtops of the two sloping-floors 6 6 are useful in stoppingthepassage of ff ballast beyond the-endsvof said floors 6 6. Dumping of the ballast or other lading between the floors 6 6 will be accomplished by manipulation of the dumping mechanism at the bottom of the car, which dumping mechanism includes the `dump door 5. When the' car is tobe used for the `purpose of carrying lading which need not 'be dumped between the tracks the entirercar between the end walls 3 3 thereofmay be filled with suchlading, only a small portion of the car between thev sloping floors 6and 10 at eachend of the car being unusedaat this time. Thatl portiony off the'lading which is located on and` between thesloping 'floors 6 6 will be dumped through thedumping vmechanism including the doors-5 5. Hrlhat part of such lading which is located between the floors '6 6 and theends ofthe car will be directed through the swing-ing, doors 9 9 (Figure 2). flhe' car-illustrated--and described' will-*shed all of1 the lading, whereby a maximum of convenience in handling is obtained. Furthermore, due' to= the if fact thatthe car is ofall -steel construction, a minimum of space will be utilized for the material ofthe car and a vmaximumof sturdiness will be had. A

Though a preferred embodiment vof the present invention has been described in detail, it will ybe clear that many modifications may be made without departing from the spirit of the invention. It is intended in this patent to cover all such modifications that fall within the scope of the 'appended claims.
