-T0 all 'whom 'it may concern: t per lla "es o'f the channels l and are proiBe it known that I, FREDERICK SEAN-mu, iteeted nHom the material transported by a citizen of the United States, residing at l inea-ns of the cover plates 10 which e.\tend Chicago, in the county of'Ceok and State ot downward vertically'froni the outer edges of Illinois, have invented certain new and usethe [langes of the channels l, and upwardly fnl lm rovmnents in Dump-Cars, of which to apointabovc thc. operatin shaft 4, thus the fol owing is a specification. protecting the latter also. 'lrferabl thc The object' of my invention is to rovidev ridge formed at the .mecti 0 edge of the improved means for opt-ratingr Hoor oors of cover plates 10 is ,protcctd by an angle dump cars, and it is especially adapted to 'that'type of cars known aas-ore ears.

In'its application, my 'invention` rovidcs simple means for closing the doors, or properly supporting the contents of the car upon the doors Whenthelatter are in closed posiiron, as illustrated at 11. Y

T ne levers IO'are provided adjacent their outer pivoted ends with stop hooks 12, and adjacent their inner ends with stops I3. livotally connected at their ends to the levers '10 and doors` 5, respectively, are links '14. 'In thc present instance I'have shown thelink so connected that in the closed position of thc door the pivotal connection. with the 'door lies outside of the `pivotal connectioii with the operating lever, but thc link may bc otherwise arranged without departing,r from the spirit of nl v invention. For the purpose of Ina 'ing a proper allowance for innpcr cctions in manufacture, l have shown the pivotal connection bctwccn thc linksl I4 and the levers 1t) ns formed h v nicnns of a stnd 15 the doors, and or the pur oses which will more clearly appear from t e'following desoription antl e aims.

'Inthe drawings-Figure 1 is a diagrammaticv illustration of an ore car showing my Fig. 2 is a cross section of t e car on the. line 2,2 of Fig. 1. Figs. 3 and 4 are detailed views of the l The center sill ofthe car to which I have shown'rnr invention applied consists of two upon the links engaging slots lt' in the levers, channel earns 1, 1 s aced apart and conthe slot giving snlhcicnt ploy to the parts to neeted togethell at tie top h v bridges compensato for slight hnlnrl'cctioos n1 nnnnlwhich support the bearings 3 ofthcoperating facture. lt is obvious, however. that `simple shaft 4.

'l`hc steel plates 7, of which the sides of thc cnr are composed, are bent outwardly and downwardlyA at 8,.thus forming a right angular rcgngcnncnt wit l thc rnlchct wheel h v gravit) studs 23, the hinges of the door and the fulcrum 24 of the lever 10 are so positionedtbat 'when the door is moved to open osition the o' ening movement will be liinitedlby contact oitrhe studs 23 with the stops 1,3. When the door is closed the studs 23 will overlie the hook stops 12.

It will -be obvious by reference to Fig. 2 oi the drawings that by rotatinc' the shaft 4 and winding the chains thereon tdie levers 10 will be elevated and through the links 14 the doors will be closed, and may be locked in closed position by restraining the shaft 4 against reverse rotation. In this position the inner ends of the levers 10 will he held in elevated osition by the chains 17 and the Weight o the doors and superimposed load will be supported upon the hook stops 12, which are located near the fulerums of the levers 10 thus relieving the chain 17 and links W'ben it is desired to,

14 from undue strain. open the doors, the detent 2! is moved from engagement with the ratchet 18,A whereupon the. weight of the doors and load causes the doors to drop until. the studs 23 come in contact with the stops 13, as illustrated in dot; ted lines in Fig. 2.

While I have described one specific embodi-rnent of my invention, all of the details herein referred to do not form an essential part thereof and the invention may be ap plied in other forms without departing from the spirit thereof.

The studs 23, above nientioned,preferably, consist of the projecting ends of a pipe or shaft extending the dll Width of the door,

i and beyond. the same at. either edge Sulliciently to engage the hook stops 12.

I claim:
