Application filed February 26, 1916. Serial No. 80,559.

coal, ballast, etc., and wherein the operating mechanismfor the doors is composed of few parts and so arranged that thesame may be conveniently operated; to provide a novel arrangement of center sill construction whereby the latter is materially strengthened; and in general to so arrange the va rious parts and devices as to provide a more efficient and economical car than, those heretofore in use.

In the drawing forming a part of this specification,- Figure 1 is a side elevation of a car showing my improvements in connection therewith. Fig. 2 is a part top plan and part horizontal section of the car illustrated in Fig. 1, and showing more particularly the arrangement of door operating mechanisms. And Figs. 3 and 4 are detail, transverse sectional views taken respectively on the lines 3-3 and 44 of Fig. 2. And Fig. 5 is a detail section of a portion of the center sills, illustrating more particularly the sheaves for the chains and the method of mounting the cross shaft on the lower faces of the center sills.

In said drawing, the car body is represented as having side walls 10, inclined end walls 11, a boxlike built-up center'sill 12 formed preferably of channels, and four extending longitudinally of hoppers AA side of the center sill the car, two on each thereof. car at the center thereof is a sheet 13 having a centrally located ridge 14, vertical por tions 1515 secured to the sides of the center sill, and outwardly and downwardly inclined lower portions 16-16, the latter portions forming longitudinal hopper sheets for the hoppers A. The outer, inwardly and downwardly inclined sides of the hoppers in the county of Cook and State of Extending longitudinally of the are formed by longitudinal hopper sheets 17-17, which are secured at their upper edges to the side walls of the car. Extending transversely of the car at the center thereof and bridging the space between the adjacent ends of the hoppers, is a substantially inverted V shaped sheet 18 and beneath which are located the auxiliary operating shafts as hereinafter described.

Referring now more particularly to Figs. 3 and 4, it-will be seen that each hopper A is provided with a center dumping door 19 and a side dumping door 20, said doors having flanged lower edges as indicated at 21, which abut each other and form a closure when the doors are in closed position. The center dumping doors 19 are each hinged along their upper edges to three hinge butts 22 disposed beneath the outwardly inclined further brace the construction at this point plates 24 are provided having vertical portions riveted to the center sills and outwardly and upwardly inclined portions riveted to the tops of the angle irons 23. With the arrangement of longitudinal sheet 13 and the members for hinging the center dump doors, it will be seen that the center sill is greatly strengthened against buffing shocks which might tend to buckle the center sill. In addition, the hinge butts for the center dump doors are out of the way of the load and the longitudinal sheet 13 forms a good shedding surface to facilitate unloading the car. The side dumping doors 20 are also hinged along their upper edges to hinge butts 240 located beneath the hopper sheets 17, there being angle irons 25 interposed between the butts and the sheets 17 to provide additional stren against longitudinal stresses. Located beneath the meeting edges of each set of hopper doors is a divert-ing shelf 26 having a ridge or apex along its upper surface whereby the load is deflected to either side of the rail, depending upon'which set of-doors is operated.

It is desirable to operate the side dumping doors simultaneously and also the center dumping doors simultaneously. For this purpose I have provided three longitudinally extending operating shafts 27, 28 and 29. The center shaft 28 is located beneath the center sill and is mounted within suitable 65. ends of the two shafts,

bearing brackets 3030, see Fig. 1, secured to said sill. The shafts 27 and 29 are mounted in suitable bearing castings 3131 which are secured on the inner faces of depending plates 32, 33 and 34, secured to the sides of the car. Between the shaft 28 and all of the side dumping doors 20-20 are flexible link connections, each consisting of a hook shaped link 35, short link 36, link 37 and arm 38 formed integrally with a drum mounted on said shaft, the linkages being so arranged that the shaft willbe self locked when the doors are in closed position, that is, there will be no tendency of the shaft to be rotated when the "car is loaded and weight is on the doors. For operating the shaft 28, I haveprovided a manually operated, auxiliary shaft 39 which extends from the. center of the car transversely to one side thereof. ()n this shaft 39 are two winding drums 40 and 41 over which wind chains 42,wsaid chains at their lower ends also winding over corresponding drums 43 and 44 secured to the shaft 28. The drums 40, 41, 43 and 44 and chains 42 are so connected that as the shaft 39 is rotated in one direction the side dumping doorswill be opened and when the shaft 39 is rotatedin the opposite direction, the doors will be moved to closed position. Similar flexible link connections are provided between the longitudinal shafts 27 and 29 and the nearest set of hinged center dumping doors 19. In order that the shafts 27 and 29 may be operated simultaneously I have provided a transversely extending auxiliary shaft 45 having worms 145 thereon which cooperate with worm gears 46 on each of said shafts 27 and 29. The auxiliary shaft 45 is extended to one side of the car where it is adapted to be operated by any suitable means such as the pawl and ratchet arrangement indicated diagrammatically in Fig. 1. By means of the worm and worm gear connections just described, it is'apparent that not only will the doors 19 be operated simultaneously but that the latter may be held in any desired adjusted position, thereby adapting the car particularly for ballast service where itis desired to dump the ballast between the rails.

It will be noted that the transversely extending auxiliary shafts 39 and 45 are not only located centrally of the car but also centrally of the respective longitudinal shafts with which they cooperate so that in rotating the shafts 27, 28 and 29 torsion on the latter is minimized. Furthermore, by locating the two transverse shafts 39 and 45 in the same space beneath the transverse hopper sheet 181the' arrangement is compact and on one side of the car, see the upper portion of Fig; 2, I and enabled to use one depending side plate 'for supporting the outer),

Although I have herein shown and described what I now consider the preferred embodiment of my invention, the same is merely descriptive and I contemplate all 'on each side of the center sill, each hopper having a pair of door openings, oppositely swinging doors for each pair of openings thus forming "four longitudinally arranged sets of doors, longitudinally extendingdirerting partitions at the bottoms of said hoppers, and two sets ofindependently operable mechanisms for controlling said four sets of doors, one of said mechanisms includ ing one longitudinally extending shaft and the other mechanism including two longitudinally extending shafts.

2. In a car of th class described, the combination with a car body provided with longitudinally arranged hoppers disposed on opposite sides of the center sill, each of said hoppers being provided with a pair of door openings for side and center dumping, of doors hinged along their upper edges for closing said-door openings, and mechanism for operating said doors, said mechanism including three longitudinally arranged shafts, connections from one of said shafts .to the side dumping doors, connections from said doors including three longitudinally arranged shafts, one between the hoppers and one on each outer side thereof, flexible connections from said shafts to the doors, and means for operating the two outer shafts simultaneously. v

'4. In a car of the character described, the combination with a car body having longitudinally arranged hoppers on opposite sides of the center sill thereof, each hopper being provided with an outwardly and an inwardly swinging door, of mechanism for operating said outwardly swinging doors simultaneously which includes a longitudinal shaft, flexible connections from said shaft to said doors, a transverse shaft, flexible connections between said transverse shaft and the longitudinal shaft; and mechanism for operating the inwardly swinging doors which includes a pair of longitudinally extending shafts, flexible connections from each of said shafts to the nearest set of inwardly swinging doors, a transverse shaft, and operative connections between said last named transverse shaft and said pair of longitudinally extending shafts.

5. In a car of the character described, the combination with a car body having hoppers provided with sets of oppositely swinging doors, of means for operating one set of said doors which includes a pair of longitudinally arranged shafts, a transverse shaft and worm gearing between said transverse shaft and both of said longitudinal shafts; and means the other set of doors including a longitud1- nal shaft, a transverse shaft, and flexible connections between the last named transverse shaft and the longitudinal shaft.

6. In a car of the class described, the combination with a car body having hoppers on each side of the center sill thereof and a transversely extending inverted V- shaped hopper sheet between adjacent ends of the hoppers, of swinging doors for said hoppers, and mechanism for operating said doors including two independently operable, transversely extending shafts located beneath said transversely extending hopper sheet.
