LOAD-DISCHARGING CAR. 7

Application filed idly lilyin-vention relates to improvements in load discharging cars, I 1 a It is an object of my inyentionto adapt cars having transversely hinged doors to efficiently deposit ballast at the side of therails and avoid flooding oftheysame when the doors are opened l leretofore it has been usual to carry out ballasting, operationsby means of specially designed; cars having doors extendinglongitudinally of the car which in themselves form deflectors for the load and prevent-flooding of the rail, but it has been found that such cars are unusual- 1y heavy and furthermoreare not well suited a for the'purpose of carrying other commodi ties such as coal, thereby entailing a heavy loss to the owners *wvhen' not in ballasting seri ice. x I

It is, therefore, it specific object ofmy in; vcntion to adapta standard type of coal carrying car, by the addition of a cornpara tively 'few simple parts, into a car suitable for the discharge and distribution of ballast and to provide means whereby such parts may v be; conveniently removed from the car when it is desired to withdraw it fro'm ballaSting work. i v a A further object of my invention is to provide a deflector which willautomatically position itself, asthe door opens, into the path ofthedischargingload, p I

My invention alo resides in the employment of a dum ing door andhopper structure'to level 0 the ballast and in certain pointed out hereinafter. p v In the drawing formin epa tof thi 'specificatioh, Fig, 1 is aplan view of a porion of a hopper car ha'yin my improve- ,ments incorporated therewith, the parts being shown in the position assumed-when the dumping doors; are fully open. 2 is a vertical. longitudinal sectionalvyiew of a portion of the cartakejn on a line corresponding substantiallytothe section line 22-of Fig. 1. Fig. 3 is a transverse sec-- other details of construction'such as will be 1924. Serial is. #25373.

the center of the car, the car having a center: sill surmounted by a central transverse ridge and formed with hoppers, arranged in pairs transversely of the car, but it is obvious that such improvements might be applied in any other desirable situation to accomplish the result intended. As shown each hopper is defined by a longitudinally ex tending sloping bottom sheet 10, an inner to be closed Joya hopper door indicated at 14, the same being hinged to the underside of theridge sheet 13 by means of the hinge butts 15, thus adapting the door to swing about its upper edge on an axis extending transversely of the car. the transversely aligned pair of hoppers in this instance, are adapted to be operated simultaneously and tothis end across-br ce is secured near the freeedges ofthe doors near their'lower ends, as indicated at 16, it being understood that said cross-brace passes from one door to the otlieigbelow, and bridges the space betw'e'euthe center sill construet-ion. or

- Inasmuch as the construction utilized is the same for both doors of a transversely aligned pair, the description will be confined to a single l 1 a y In y g but my vention, I mploy a deflecting member 17,.which may beef any desired form, eitherfiat or c urved in cross section, but'preferably consisting of a sheet P te vi g he s e th e t ai d ow w r ly. at 18s t provide u e hve eql and for the purpose. of imparting stiifness to the saidpla'te. .Al'preferred manner pt mounting the said. deflecting nembero'n the car structure consists in pivoting one d t e o c o th lo rv e ge of. t e do r The two doors of 14, and supporting the opposite end thereof v directly from thestationary floor 10. In eaI- .rying out'this'construction, a pair of hinge brackets 19 are preferably secured to the cross-brace 16 of the door, and a P811207:

hinge straps 20 are secured to the deflecting member 17 and to the brackets 19 hereinafter described. The pair of hinge 'straps 20 are' spaced apart on the member 117a suflieient distance to: lie between the pan; of h nge brackets19 and thus prevent undue side.-

wise movement of the parts. A rod 21 passes through the hinge brackets 19 and hinge straps 20 and a ferrule 22 is adapted.

member 23 which is preferably in the form,

of a Z-bar; said member is provided with a slot 2 1 through which the deflecting member 17 extends and whereby it is supported in position when the. door is opened. mile the slotting of a Z member in this manner forms a convenient construction, it will be understood that other constructions may be used, as for instance a heavy angle iron may be utilized and a hanger of suitable form may depend therefrom to sustain the weight of the said deflector member 17.

When the door is in closed position the deflecting member 17 is adapted to moveupwardly to a position beneath the sloping floor and to be there supported by means of a runway preferably formed of a plurality of angle irons 2525 supported at one end by the stiffening member 23, and at the other end by a stirrup member 26.secured to the sloping sheet 10 and having a horizontal portion secured to and extending between the angle irons 25. Said angle irons 25 are preferabl curved as indicated at 27 to facilitate the s iding movement of the deflecting member 17 thereon as the door moves.

The-opening and closing of the doors is preferably accomplished by means of adevice such as illustrated in my prior United States Patent, No. 1,418,907, issued June .6,

1922, inasmuch asthis mechanism includes the essentials for-opening the door and also for maintaining the same fully open, and limiting the o ning movements thereof, thereby permitting the operation of the car as a ballast spreader .in either direction and the utilization of the transversely extending door 14 as a leveler for the ballast.

The said operating mechanism utilizes a horizontal operating shaft 28 mounted in suitable bearings 2929 secured to the hopper structure. Said shaft 28 is extended to one side of the car only, where it is provided with a safety operating device 129 embodying aclutch connection for the purpose of ensuring the safety of the operator on opening the doors. Applied to the shaft 28 at a' point thereof beneath the center sill construction is a hub casting 30, said hub casting being rigidly united with the shaft" 28 and secured against rotation relativelly thereto, and provided with a radially exten ing arm 31. Operative connection between said arm 31 and the door is effected by means of an elongated link 32, the latter having a pivotal connection as indicated at 33 with attached to the door. The link 32 is provided with a'radial shoulder 31 onits upper side which is adapted to. engage with a shoulder forming flange 35, formed on the arm 31, at the end of the full opening movement of the door, to thereby limit the relative swinging movement of the arm 31 and the link 32, the parts in the open position assuming-the position indicated by full lines in Fig. 2.

The operation of my improved car is as follows: assuming the door is closed and the parts are positioned as indicated in Fig. 2 conventionally by dot and dash lines. The operator rotates the shaft in an counterclockwise direction as viewed in F ig. 2, and the door opens, drawing the deflecting member 17 outwardly therewith. the onrush of the discharging material assisting the opening movement of the door to its full extent when the ivotal connection 33 will drop slightly be ow a line passing through the pivotal axis of the pivot connecting link with the door and the center of the shaft 28, thereby automatically locking the door in open position, as will be understood. The discharging material then slopes down from the sides of thedeflecting member 17 to.

gresses the ballast is leveled off either by the door 14, or by the stiffening member 23 at the lower edge of the sloping floor sheet 10. If the car is moved in the direction indicated by the arrow 39 the door acts as a leveler being held in its opened position by the mechanism above described. and if moved in the opposite direction thereto. the leveling is accomplished by means of the stiffening member 23, and the door in this instance is still maintained in its open position by means of the interengaging shoulders-35 and 34, formed on the arm 31 and link 30 respectively. In this. manner a section of roadbed may be ballasted very economically without the use of specially designed cars and when such ballasting operations are concluded, the deflecting members 17 may be entirely removed from the car and conveniently stored until such time as required, and the car in the meantime may be usedin the hauling of coal or similar commodities.

While I have shown a preferred embodiment of my invention, it isto be understood said arm, said link being also pivotally that the same is susceptible of many modifications as for instance in the disposition of the member. 17, which may be mounted entirely on the carstructure orin various other ways without affecting; the result attained, and I wish to claim all constructions coming Within the scope of the claims appended hereto.
