To all 'whom it may concern:

Be it known that l, FRANK lneonnsnr, a citizen of the United States.v residing at St. Louis and Starte ot Missouri, have invented a. certain new and useful Improvement in Dump-Cars, of .which the follmving is a full, clear, and exact description, reference being had to the accompanying drawings.

The object.. of this invention is to provide simple and etlicient means torreceiving tlc impact' ot dropping doors in dump cars, 1.. ef venting any distortion thereot.

The invention isl welladapt'ed for cars of the Ingoldsby typefvrherein there is a central longitudinal member, to the opposite edges ot' which are hinged doors norn'iaily horizontal when closed, but ,rhich downward at their outer edges to discharge the load. In such cars, I havecustomarily provided a pair oi bumpers to receive the door as it drops, these bumpers being conveniently located a suitable distance inward from the end of the door. These bumpers have engaged springs carried on the under side of the door by the next to the end floor beams thereof. Vit-h such arrangement l have found there is a tendency ot' the eX- treme corner of the door to bend downward from successive impacts.

The present invention is designed primarily to preventthe downward bending at the corner of the door. Itv provides a aprire extending crosswise olf the car carried b the central structure and adapted to receive the doors on its opposite sides. This spring is shown as located in position to engage the end licor beam and thereby support the corners of the doors-the spring being used in addition to the usual bumpers and door springs. In some classes or" cars, however, my new spring carried by the car structure may be used in place of the bumpers and tloor springs, and thus receive and support the whole. impact of the dropping door. My spring .so has the advantage. ot acting as a strut-tie across the bottom oit the central structure di the ear. These features, and other features involved in the securing of the ring', will be hereinafter' more fully exixglained, and the essential characteristics setoutin the claims.

In the drawings Figure 1 is a bottom plan of a `portion or a car el'nbodying my invention* Fig. 2 is a cross section of such car. Fig. 3 is a detail in the same plane with Fig.

prised of the vertical plates 12 a surmounting `ridge 13, the crossbracing plates 14 be tween the outer sides of the vertical plates and the under side of the projecting ridge7 and the through angle bars 15,.extending lalong the lower portions of the plates 12 at their outer sides, being riveted to them.

16 indicates dumping doors which are hinged their inner ends `by means of ioor beams 17 which are'connected by hinge pintles to the straps 1S secured. to the cross plates 11i. The outer ends of the doors 16 abut the lower edges of the car side, where they are supported by suitable hooks 19 on the sides or the car engaging beneath the projecting ends of the floor beams. The floor beams extend through the Z-bar 27, the pur )ose of which is to stiilen the outer edge of the door.

2O indicates rock shafts supported by some of the straps 18, and 21 indicates arms on these rock shafts adapted to engage the under sides of the doors and raise them when the shafts are properlyrocled.

23 represents a suitable -beani extending rosswise of the car beneath the angles 15 and rivet-ed thereto. rl`his I-beam is cutoii" diagonally as shown, and the end of its lower` iiaiige and the lower portion of its web forms a bumper adapted to engage a leaf spring 25 carried oul the under side of the door. These leaf springs are shown as carried by the door beams 17 which are next to the end iioor beams of the doors, as seen in F ig. l, and the bumpers are correspondingly located.

The construction so tar specifically de-v scribed is employed in cars l have hereto tore devised, and which are the subject of various prior applications. ln those applications, the construction of the center meniber, the doors, the door raising mechanism and the bumper and springs are set ont. and claimed. The presentapplicat-ion relates particularly to my new bumping spring car- CIK ried by the center member, which will non7 be described.'

My nepY bninpin pring consists of a sub stantiaily rectanguiar bar 3G extending crosswise of the car beneath the angles l and curving downward. near its ends, as shown at 3l, rIhis spring is shown as so lofd that its curved portion receives the Ver 1.' cal web oi 'the endmost iioor beam 17 The left hand half of Fig, 2 door beam l? engaging the Y The spring is sr iported first by shackles which ezfrtend around it7 and project upwardly through ope gs in thehorizontal iia We ot the angle loi nnte Se sereni'- ing onto ich projecting ends oil" the shackle. This siivports the spring without in any manner weakening it at Iits point ot iler-nro To prevent the :ing shittingvinng tudinally, however, I pass a bolt through it, which extends into the horizontal flange of asmail angular piece 36 rivet i' side of the plate l2. The c" the spring bar for this bols located far enough haelt -from the point of fiemire so that it does not weaken the spring. @he of the same rivets 3'? which secures the angle to the plate 2O ay also secure the piece 36. This same rit-'et may likewise pass through the Hangs i0 of the cross plate 14..

It will be seen that the spring bar is, by the construction described, held rigidly in place, While its ends are in position to receive the doors and prevent any distortion of the same. The intermediate portion of the s `ng bar acte also as a strut-tie across the con-s: member, binding together the two plates lf2 Witii`-tiicir angles 15 and assisting in bracing the center member.

I-Iaving thus described my invention, I claim:
