To aw 'wlwm'z't may 00ncem:

may be raised and lowered upon theopposite side'as a center of movement.

In the embodiment of my invention illus-i tratedin the drawings'and described below,

the actuating mechanism for the door, or

movable floor sections, comprises rails adjacent the end of the door opening and slop.- ing downwardly toward the center thereof, together with reciprocating shafts supported upon 5 id rails and in turn supporting the door, hese shafts being reciprocated by chains and winding shafts.- It will be obvious, however, that the broad principle of my invention may be applied in connection with other forms of mechanism for raising,

. lowering and supporting the opposite edges of thecmovable floor sections or door. In the more specific aspect of my invention, however, I consider the operating mechanismillustrated and descr'bed as well adapted for the purpose intend d.

In the drawingsFigui-e 1 is a side view of a car einbodyingmy invention. Fig. 2 is a plan view. Fig. 3 is an end view. Fig. 4 isa centraltransver'se section. Fig. 5.is a fragmentary view in transverse section corresponding to part of Fig. 4.. Fig. 8 is a fragmentary view in longitudinal section showing the door open. Fig. 7 is a detail view of part of the supporting rail and operating mechanism. Fig. 8 is' a fragmentary side view of the central part of the car showing the door closed. Fig. 9 is a fragmentary view in longitudinal sect-ion 'through the door and part of the sloping end wall. Fig. 10 is a fragmentary view of the door in open position, the illustration being confined to theelevated side of the door whiehacts as 'a center of movement while the opposite side is being lowered.

While'my invention may be employed in various connect-ions, it is especially adapted for use-in connectionwith cars. of the type illustrated, thesame being commonly used for transporting ore and" like material.

The car' illustrated'comprises a floor having end sections l slopingdownwardly toward the centerof the car and vertical-side walls 2bet-ween which a dooropening is framed at thecenter of the car. Side wall sections 3'1ncl1ne1-nwardly from the vertical side walls 2 adJacenttheir lower edges, thus restricting to "some extent the discharge opening, and in connection with the lower part of the slde walls 2"form'ing a housing for the operating winding shafts 4. The

winding shafts 4 are supported in bearing plates 5 which extend between the lower part of the .vertical side wallsand the inwardly inclined side wall sections '3. Angle irons 6 are secured to the lower edges of the vertical side walls and plates 7- extend between and, are secured to the vertical side walls and Xinwardly inclining sections -3. The bearing, plates 5 are secured by' means of angles 8 which are riveted thereto and to the plates 7 It is obvious, however, that any suitable means may be adopted for supportmg the winding shafts. Preferably, the

lower edges of the inclinedends 1 and of the inwardly inclining side wall sections 3 are bent downwardly to a vertical position at their lower edges to coact with the movable floor section ordoor 9.

Extendingacross the car just outside of the ends of the central opening are rails 10 secured at their ends to the bearing plates 5 and angles 8, and inclining downwardly to the longitudinal center of the, car. The upper surfaces of the rails 10 are formed with short horizontal sections 11 adjacent their ends. Shafts 12 rest upon the rails 10 and support the door 9. Winding chains 13 are secured at their ends to the reciproeating shafts 12 and winding shafts 4, respectively, and through the rotation of the winding shafts 4 the shafts 12 may be drawn upward to the position illustrated in Fig. 4, in which position the shafts 12 rest upon the horizontal sections 11 of the rails 10. In this position the weight imposed upon the door 9 has no tendency to cause the shafts 12 to travel downward upon the rails 10, and hence in this position the winding chains 13 are relieved of all strain.

The doors 9 comprise an upper plate 14 reinforced by transverse Z-bars 15 and by a longitudinal plate and I-beam 16 and 17, respectively, located at the center of the door and secured to said Z-bars. vDownwardly projecting bearing plates 18 are secured to' the Z-bars 15 adjacent their ends, said projections 18 being rounded upon their inner surfaces 19 to conform to the curvature 'of the shafts 12 and when said shafts 12 are raised to the position shown in Fig. 4 the bearing plates 18 rest outside of and engage said shafts.

When either edge of the door is lowered by permitting. the shaft 12 to travel down the rail 10 to the center of the car the projections 18 at the opposite edge of the door will remain in engagement with the shaft 12 atthat edge thus forming a hinge connection about which the door may open, as illustrated in Fig. 10. The action of the door when lowered at either side is illustrated in dotted lines in Fig. 4. ltn order to start the shaft 12 upon its downward movement on the raillt) came 19 are secured to the shafts l. Upon reference to Fig. 4, it will be obvious that when either shaft 4 is rotated in direction to unwind its chains the cam 19 will contact with the corresponding shaft 12 and forcibly move it from the hori zontal part 11 of the rail 10, after which the weight of the door and superimposed load will carry the shaft 12 downward along the rail 10, thus unwinding the chain from the shaft 4. The chains 13 may be attached to the Winding shafts and reciprocating shafts by any suitable means. in the pres ent instance I have shown the chains attached to lI-bolts 20 extending through said shafts. 4

For the purpose of operating the winding shaft 4 any suitable mechanism may be employed. ltn the present instance I have shown levers 21 pivoted upon the winding shafts and carrying reversible pawls 22 which coact with star wheels 23 secured to the shafts 4:. In order to prevent reverse rotation of the winding shafts when the reciprocating shafts are being drawn upwardly to close the doors, I provide-detents '24; ooacting with pinions 25 secured to the shafts 4..

V The underframe of the car illustrated comprises center sills or draft sills 26 en: tending inwardly from the end sills 27 to the central door opening, the load being carried from the center part of the car to the ends by the plate sides 2. The sides 2 may be reinforced by channels and angles needaao 27 and 28, and the ends of the car are sup ported by struts 29 extending upwardly from the angles 6 to the upper ends of the inclined ends 1. Preferably the shafts 4 are provided with spiral sheaves 30 upon which the chains13 wind.

From the foregoing description it will be apparent that I haveprovided a car having a dump door, either edge of which in connection with the coacting parts may act as a hinge while the opposite edge is being raised and lowered, the connection of the opposite edges of the door with the operating mechanism and car structure being such as to permit movement about either edge as a center. By means of this construction the contents of the car may be dumped at either side without the employment 0 a plurality of doors,-and without raising either edgeof the door to accomplish the desired object.

if would have it understood that I do not desire to limit" myself to theprecise con struction of partsshown in the drawings and herein described, as various modificationsi or alterations may be made without departing from my original invention 'as defined in the appended claims.
