conero Y; 'rondine-ii -Thdesiding stru 'ralieeture of the body 4in giv-i'ng'to hot-h the side and end ownivardly divergent inclination, which affords a large opening for the discharge of the load, sind ohviates any tendenoy of the loadv 'to stink' or adhere to the side 25 or end Walls in discharging. Preferably, and as herein. shown," the sidewalls are straight, While the end Walls are of agenerally rounded 'form to afford the maximum loed capacity possible Without interference with the truois .ln disoharving. Preferably, and es herein shown, eee i end Wallis made u of a plural ity of straight sections disposed at an angle to each other and tapered along their lines of junction with each other and with the side Walls, conformably to the general scheine of downwardly diverging Walls throughout the body. In the preferred. arrangement oi' hinged 'doors forming 'the bottom, as herein shown., I provide a pair of side doors 'which are hinged to the lower margins of the side Wells of the body, and a pail of end doors disposed and operating at right angles to seid Side doors and hinged to the lower margin of the intermediate sections of the end Walls of the body.

The'invention Will be reedily understood when considered in connection with the aoeompanying,r drawin s, Wherein,-

Figure 1 is a to p an View of my improved cai'b0cly, with t e underfrarne supporting the same also a peering in skeleton outline; Fig. 2 is a side e evation of F' 1; Figs. 3 and erre' eniarged cross-sectiona vieWson the 'the sec-rione of 'the end lines .33 and 44, respectively, of Fig. 1, Viewed in the directions indicated by the er rows. u

' 'Referring to thedrawings, 5 may designate as an. entirety the skeleton. of a steelum derfrarne, and 6 'the trucks on which the same is mounted, whioh, parts may 4be of any ordinary or usual eo] -truction and form only ooperating features in their relation to the present invention.

and braced in the ina-nner hereina ter de scribed.

The car-body itself ine-de up of e pair of o ositely disposed side wells 9 that ere suitm all-iig secured to and within the side sills 7, and are so inclined es to he downwardly di verwent relatively to each other, and e. pair of similarly inclined end walls, each. of which is made up ot' an interniediete section i0 and side sections l1, said intermediate and side sections being suitably beveled and mitered to' forni proper joints or connections Vwith each other and Twith the side wells, as Clearly indicated in l.

The j cinte at the junctions of the end and side Walls, as Well es those et the junctions of fills, ere preferably formedv by engiediiare riveted to the Walls and to each other, indicated in the drawings and in a manner Weil understood in the art,

this detail of construction forming no feature of the present invention. The end Walls are supported, through the intermediate sections 10, on the center sills S which `pass therethrough, as bestshown in'iigs. 1 and 4,-andare braced by struts 12 vemmer,ting said intermediate sections 10 with the center sills 8 outside the body.

The bottoni of a series oi." doors hinged thereto; thev preferred arrangement herein shown comprising a pair of oppositely disposed side doors 13 that are hinged at 14 to the lower edges of the side Walls 9, and a pair of oppositely disposed end doors 14 arranged and ocperatin at a right angle to the doors 13., an hinge at 15 to the lower edges of the intermediatesections 10 of the end Walls. As a convenient means for raising and lowering said doors, I have shown a central longitudinal shaft 16 journaled on across and between the end 'T may designate the 4 side sills, and Sthe center sillsof the under# frame, on which the oar-body is su ported the cardenaly is made up of4 walls,with chains or cables 17 and 18 depending therefrom and connected to the inner or freemar ins of the doors 13 and 14, respectivel usua hand wheel 19 and awl and ratchet datent 20 for operating andllocking the same.. From the foregoing it will be seen that my present invention provides a car-body not only of considerabl greater area at its bottom than at its top, gut also opening through out the entire extent of its' bottom for the automatic discharge of the load, and further provided with downwardly and outwardly inclined walls all around, which revents the adherence of any part of the loadp to such side walls and insures a clean discharge ofthe entire contents of thebody. i I am aware that car-bodies having dumpmg bottoms and upright walls in part outwardl inclined from top to bottom to facilitate ischarge have been proposed; but so far as I am aware my 4present design, affords the first instance of a car-body of this type walls, and a hinged bottom,

wherein the downward divergence. of the up' right walls is applied throughout the entire extent oi the latter. 1` I claim:

1.l In 'a steel gar construction, a car-body having downwardly divergent strai ht side walls, downwardly divergent roun ed end' 'substantially as described. 4

2. In a` steel car construction, a car-body having downwardly divergent side and heshaft 16 is provided with the rounded end walls, and a bottom comprised wholly of a plurality of hinged doors, substahtially as described.

3. In a steel car construction, a car-bodyto," of the car-body, substantia y as descrl ed.

4. In a steel car construction, a carbody having downwardly divergent straight side walls, anddownwardly divergent rounded end walls, each of the latter com rising a plurality of tapered sections marginally unlted to each other and to the ends of said side sills, siibstantially as described.

' 5. In a steel car construction, a car-body comprising downwardly divergent strai ht side walls, downwardly divergent rounded end walls, each of the latter including an -intermediate and end sections" tapered and marginally united to each other and to the ends of said side walls, and a dum ing bottom formed by doors hinged to 151e lower edges of the intermediate sections of said end fwalls, substantially as described'.-
