This invention relates to the art of dump cars and is more particularly concerned with a novel'. construction of ya lcar designed for dumping movement-'in'two directions.

f A dump car madein-jaccordancewith this invention `comprises generally facar frame which ismounted on the lwheelftrucls and which operatively supports the dumping body. An important object in View is theprovision of a car -frame which is characterized constitutes theso called backbone ofthe frame., Inasmuchy as the fframe necessarily accommodates dumping action onthe partof the dumpingzbody itis importanttolocate a structure affording the main rigideects cenf trallyand'longitudinally of thelcar where it ment. i

"More in detail, this invention contemplates a car frame jconstruction'having upper and lower. endsills at,y each end ofthe carwithy i vboth the end'sills at one endconnected to both the end'sills at the other end by the center sill. The upper endsillsfconstitute a trackway on which the car. body operates while dumping", while-the lower endl sills yarefconnected :by side ysills which aredisposed beneath the level `ofthe'center sillvat whichV locationfthey do not interferewith the tilting movement. Another important feature of they present invention is associated jwiththe mounting of latchfmeans for maintaining `the dumping body in normalposition and which ylatch means is operable to permit fof; dumping movement; In vaccordance with this Vinventiona' pair ofy latch members yare pivotally mounted' at oneend of a pair KAofinteritting plates that are Icarried in offset relation 1, by the body end walls. The7other extremities of -the latchm'embersgare formedwith hook` meansdesigned for' engaging1 thevpinsc'arried V'bythe up er .endsillsl at t n l efopposite ends thereof," thery more detailed objects and ade yantages such as arev associated with the pro-V vision'fof av practical dump car of. the'type notediwill in part become apparent. andlinV description partbehe'reinafter stated as the of the invention proceeds; A

- rFig. 4 is* a transversey verticali section through the car frameand istaken .about on they plane represented by the lline- Fig.V i l. Referring now to thev drawings, the ldump is shownas comprising generally al car'frame v A mounted. on trucks 2B comprising .axles 6 andjjvour'nalboxes 7 and operatively support-l y ing a dumpingbody C; ',Thejlatter -is -nor- :mally-'heldv' inV non-discharging position thereonby latch `means to be lhereinafter. describedin detail.

The car frame yA .includes plural: endfsilll .A

constructions at each end of-thecar'which are substantiallyv duplicates f and which are connected by a center sill-'10. 'IKhe'fendrsilll pris'ing an upper end sill and rocker support c 11`and a lowerend sill 12 which is shorter than the upper end silland has its center line coincident with thev upper end 'sill 11. LThe `center sill '10 isof I beam: formation and 'aiixed to the ends thereof onieach side of lthe webportion are a pair of angle- bracketshavinglegs 13 and 14 rivetedrespectivelyto the centerfsill and upper end sill 11, which latter is of channel formation. i

Supplemental: angle bracketsv15-arelsimiv larly securedA to the center sill `10 and lower sill y12; alsofof chan'neliformatiomxandiclips 65 "10 tothe end vsills .12, 4to yrigidly connect the f f;

connectithe ,lower flange of ythecentersill respectiveparts." f The lower 4end sills `12 "at eachend of the car areconnected at their e`xtremities byrolled'channelsidesills 16. The

umv

V is connectedwithtside sill 16 jas by rivets and this leg 19terminate's asli'ght distance (above the side sill 16 as shown in Fig. 4. Gussets 66 are also provided to reinforce the ineinbers 12 and 16 at the four corners of the -un- 15 deri'rame, as shown in Fig. 3.

The lower end sill 12 carries draft means for the car in the form of a coupling designat-ed 2O which is anchored 'to the end sill 12 as shoWna-t 211. The upper end sill ,11 carries latch-engaging pins 22 which are braced by brackets 23 having oiset portions 24 connected with the Vinain ybody portion of the jbrackets by an inclined intermediate portion 25. per end sill 11 by Ariveting land the oilsets 24 are apertured to receiveV the;yp'ins l22, As above notedthe 'end sill 11 is ofcha-nnel vformation and the upper iiange v'thereof designated l26 is ,provid-ed with a series ofequidistantlyspaced openings 27 for Va purposek to be la-ter specified. i

Trucks B are connected to the frame A by the angle plates 28,the'angularlegs `of which are aziixed ;to the journal boxes of the `trucks and rthesside sills 16 respectively. :Brac'ing means `at the middle of the car frame is provided in the form Vof a tie plate 29 which is attached-to the side sills and center sill Vrespectively lb ysufitable rivet connection. i 10 Dumping 'body' C is yci' general box formation and comprises a floor 31whic`h may be'oaf plank-,end Walls-32and-sides den'ed by swingdoors 33. The latter may include a sheet metal wall 34 :that is braced against bending 15 hy sti'iening means inthe form Iof angle bars 35.. The planking ofthe floor `31-may be faced with vsheet metal plates `6() andy-61 on the top and bottom faces. The doors `33 are pivotally mounted `at the t'op of the `end walls y50 32 as indicatedat 36 and door lock mecha- 'nism for maintaining the doors in closed@ osi'tion and Ifor permitting of thei'r swinging is associated with the lower edge of the door and the side edge of the floor 3l. This door 'H5 Tlock mechanism is shown at 37' and may be ofthe conventional type. i

The structure which rockably supports the body C on the tram'e A comprises rocker trames 38,one being lat'tacl'ied to each of the end Wal=ls2 32y Oneof the rocker frames consists o-fa -U-`slfrapedcasting having a flange 39 parallely with and riveted to the endwall andfaeurved ilange140 Ialt right angles thereto.

` This angular casting -Iis reinforced by -ribsi41 05 which are integralwith the respective flanges.

Brackets 23 are anchored tothe up-V A cross piece 42 connects the legs of the U and this cross piece, together with the lange 39, is anchored to end wall 320i the body C.

The flange of the rocker frame 38 is provided at the bend of the U with teeth 43 that are complementary to the openi s 27 in the endsillfflangeQ. Y Senseo! these 4celda-43 are at all times received in the openings 27 and functionto prevent lateral displacement of aie-badly c Twist respect to une frame A. Y T0 the end or inciting r'ekinginovjement ofthe body C chains 44 are provrded'atbach "side of the'car and these chains 44 have their `ends afliXed to Athe .body C and the frame A respectively as ' shovv'n rat 45 and 46.

A Pivotal mountings -for thelatch :members 47 are provided 'in the ,form of 43 which are carried :by the end Vwalls 32 - andfoifsets 49 and 50 of inter-fitting brackets-51nd 52,which are suitably y mounted 'onf nthe end wal-Is `532'. 'lhe oil'set 50 has a. flange 53 rthat is connected to the inclined iportion -54 of the-bracketl as by riveting toprovide a rigid structure. The pins `48 4extend through apertures inthe latch members 47 vvh-i-lewthe 4other extremities ofthe latch mem-bers are recessed as show-n Vat 55 to provide hooks 4for engagement with the pins 22. In operation the teeth 43 are received Ain openings?? when the c'ar is an Vupright or normal position in which dumping is prevented yby the hooks of therlatch vifnge'rn'lfier-s 47 engaging `the pins 22fgto maintain thisnon'- discharging position. When the car is to :be dumped the `door33 -isreleased-by proper operation of the rdoor lock 37 adiacent the side on which the contents fare to befdnmped, and the latch'iniember 47 lon thesideopposi-te that on which the contents are be dumped is swung free of the pinsf22. Under-these con'- ditionsgravity Vaction will have to be supplemented lonly very slightly to cause the body C to tilt on ythe-rocker frames. As the Abody rocks the door 37 swingsopen and the cointents anedisdaarged. It is notable Ythat the chains j44 are effective to -li'mfit the extent of thejtilti'ng movemeilt-V While a preerredspeciiic embodlment is hereinbefore 'set forth it is understood that I `am not to be limited to the exact construe tion illustrated "and described because various modications ofthesedetilsfnray be provided in `pitting the invention practice Within the purvliewfof the appended claims;
