This invention relates to that class of cars having drop bottoms for discharging the load and more particularly to hopper bottom cars for carrying and discharging iron ore andsiinilar materials. Ore cars are required to be of short length in'order that a train thereof may-be placed so that eachcar will be locatedover a pocket in the ore dock, the spacing of said pockets conforming to that of the hatches of ore carrying vessels. On account of the short lengths of ore cars the space longitudinally of the car between the inner truck wheels is so small that it is difficult to arrange openings sufficiently large to prevent the 'ore from bridging or arching over these openings.

In my Patent No. 835,167 granted November 6, 1906, I have illustrated, described and claimed an ore car of the standard length and having a door opening in its bottom of such size as to prevent the bridging of the ore and insure discharge of the load.

The present invention is an improvement for its objects to simplify the door construction so as to dispense a ith the transverse doors of said prior patent; to provide operatingmeans for the doors which can be operated from either side of the car and by means of which both ends of the doors will be simultaneously lifted. and lowered; to provide a construction whereby a steam pipe'ran be conveniently inserted above the bottom for thawing the lading in case of freezing; to provide an elevated end platform between the end'of the body and the end sill so as to enable trainmen to pass along the train; to provide an improved connection for tho inner ends of the draft sills, as well as other inirovements and details .of construction hereinafter described and claimed.

In the accoin anyingfdrawings Figure 1 is a vertical centra longitudinal section through a portion of. a car embodying the invention; Fig. 2 is a plan View of a portion of said car with parts broken out; Fig. 3 is a vertical transverse section through the car, and Figs. 4 and 5 are detail views of portions of the door operating mechanism.

on the car described in said patent and. has

PATENT-OFFER Patented April 13, 1909.

The car is of the hopper type having the side walls 1 vertical for the greater portion oftheir height, but preferably having the lower portion, as at 2, slo ing inwardly so as to contract the body sightly toward the bottoml The end floor plates 3 are sloped atv edges extending toward the central line of the car so that the doors in opening swing downwardly and outwardly as shown in Fi 3. The car is not provided with center sill s and therefore provides an unobstructed opening of slightly greater width than the distance between the tracks and of somewhat greater length than thedistance between the inner truck wheels, as clearly shown in the drawings and as described in my patent above identified. In my prior patent this mpening was closed bviincans of four doors,

doors. The present car has only-two longitudinal doors, but the ends thereof are provided with 7 upwardly sloping portions 7 which when the doors are closed form substantially a continuation of the sloping end plates 3, said the ends of the mm to projgctr ver the ends of the Wheels. The upwardl pro'ecting portions 7 on the doors are formed preferably b pressing'door plates to the desired shape, afthough if desired they may be formed of separate plates suitably secured to the main door plates,

The free edges of the doom have connected thereto the suspending beams 8 formed preferably of pressed plates as shown and connected to the upturned end portions of the doors by plates 9. Operating chains 10 are connected to the ends of the door beams at both ends of the door and pass upwardly over suitable sheaves 11 on transverse shaft 12 mounted in the inner ends of the draft sills 13. The chains are connected to suitable drums orpulleys 15 onwinding shafts 16 located transversely of the car. The windtwo longitudinal doors" and two transverse uCpturned portions permitting ing shafts 16 at the two ends of the car are connected by a longitudinal shaft 17 provided with worms 18 engaging worm wheels 4 19 on said winding shafts, so that both shafts are operated simultaneously, in order that both ends of the doors can be lifted and lowered by a singleo erator; The longitudinal shaft is provide with a bevel pinion 2O meshing with a similar pinion 21 on o erating shaft22. The latter shaft exten s entirely across the car and is provided with squared ends or other operating connections, so that it can be operated from either side of the car. The door operating mechanism described is such that a single attendant'can operate the same from either side of the car. The worm and worm wheel connectiops between the operating shaft and'winding-shaft also provide in themselves a lock thereby dispensing with separate locking means. Stops, generally indicated at'23, are preferably emloyed to prevent turning the winding shafts m the wrong direction.

The outer edges of the doors 5 are spaced somewhat from the ho per side plates 2, as shown in Fig. 3, there y permitting the inlsertion of a steam pipe to direct steam along the inner surface of the doors 5 in order to thaw the lading in case of freezing. The outer edges of the doors are located sufficiently high so that the lading cannot escape. It is mere y necessary'to ha a the door edges slightly higher thanthe angle of repose of the ore.- This provides for the ready thawing out of the load and without'e-utting holes in the side 'of the car or the doors, through which the ore would be liable to escape.

The draft sills 13 cxti .d inwardly beyond the body bolster 26 which is provided with the usual center bearing plate 27. The inner ends of these sills are connected to the sloping floor plates 3 by means of gusset plates 28 riveted. to the draft sills and to the floor plates. The tendency ,of the draft sills, due to their supporting the inner edges of the doors, is to rotate-on a horizontal axis around the center bearing plate 27, and the. connections between the gusset plates 28 and lloor lates 3 are so located that the rivets 29 are p aced under shear by the tendency of the draft sills to rotate .as stated. In other words the line of rivets 29 lies practically in an arc struck around the bolster center plate as a center. By the connection described the inner ends of the draft sills are practlcally sus ended from the sloping end floor plates ant in a manner to put the rivets under shear and thus utilize their maximum efficiency. The winding shaft and transverse operating shaft are mounted in or on the draft sills. The extreme innerends of said draft sills are pressed slightly toward each other as shown in Fig. 2, and also bent slightly downwardly to prov de convenient bearings for the guide sheave shaft 12. The

lower edges of the sloping. floor plates are stiffened transversely by the angle plate or bar 30.

The necessary steep pitch of the end floor plates 3 prevents th ody being extended out to the end sills. such a'large space between the ends of the bodies oftwo coupled cars as to prevent the trainmen from passing over when the train is loaded. To permit this I provide elevated end platforms 32 near the tops of the bodies of the car and extending from theends of the body practically out to the ends of the un derframe, thereby permitting trainmen to traverse a loaded train. This platform also serves as a convenient place for operation of the brake-hand wheel 33. Ladders 34 are provided on each side leading up to these platforms and referably one of said ladders is provided wit one broad step 35.

The top edges of the side plates are provided with chords of substantially diamond shape as shown at 36, these being formed of Consequently there is pressed plate, and preferably being integral portions of the g body side plates. These diamond shaped chords give the necessary strength and do not present any'surface for the lodgment of ore.

The car illustrated has numerous parts not referred to in the foregoing description but as they form no part of the present invention, a description is deemed unnecessary.
