To allwhom 'it may concern:v l

Be it known that I, CARL P. As'rnoM, citizen of the United States, residingat Hasbrouck Heights, in the county of Bergen and State of New Jersey, have invented certain newand useful Improvements in Dumping- Cars, of which the following is a'full, clear, and exact speciiication. y

This invention relates to. dumping cars, 'and more lparticularly has reference to cars wherein the bodyis Y'mounted to be moved laterally and simultaneously turned 4 The object of the inventionis to provide generally a slager cinder dumpinglcar of the type shown in patent-issued Marc 17, 1908,

'to Munson H. Treadwell, wherein a tilting and laterally movable car body is provided Y. with a fluid. checking device preventing exing to this invention iiuid around the piston. Means is also'pro-` vided for varying or throwing entirel out of v or either auxiliary by-pass,

connection with the description of the ac-l cessive movement of the car body when moving to and from dumping position. In such a iiuid checked car body, it is desirable to allow the car body to have a fastermovement as it approaches the outer end ofthe dumping stroke, frame with ashock, and thereby dislodge the skull which forms within the pot. Accord- I accomplish this object by providing the fluid checking cylinder with means whereby the checking effect is automatically lessened, 1 and thereby the speed increased, as the car body approaches its outer end. complished by providing auxiliary by-passes on the fluid cylinder which become effective as theend' is reached to reduce thech'e'cking eiiect by permitting'greater circulation of operation, as may be desired, either t e main for purposes which will more fully hereinafter appear in companying drawings, wherein- Figure 1 is an end view of a dump car embodying the invention, Fig. 2 is a detail view showing my improvements, and Fig. 3 is a detail view showing the auxiliary by-pass valve.

-1 represents railway trucks 2, -and provided with the usual coupling equipments used on cars of '4 `the imderrame this type. At each end of are supporting pedestals 5, raised somewhat above the top ofthe frame, and these pedesin order so as to bring'up against the As shown herein, this is acever the cylinder t ing 'in block 27.

an underframe mounted on.

tals ,havey their upper faces formed as trans-v verse tracks,v on which the car body is supported in such manner as to permit the body to move laterally, and simultaneously tilt, in either direction.

6 represents a-car slag or cinder ladle, carried by a frame?, provided at each end with trunnions which restorr the respective pedestals 5. Each pedestal has a rack 10, and meshing therein are ears'. 11, rollin on the racks i0. T e power mec ianism 'for operating the car bodyy comprises a reciprocatory cylinder 15, mounted on the pedestal 5 and reciproeating between horizontal guides 16, 17.

18isl a stationary hollow piston rod, having a piston 19, and at each side ofthe piston 19' are inlet ports throufrh which i'luid ypressure, as vair'or steam, wil be admitted to reciprocate the cylinder. Each-end of the hollow rod 18 is connected by a pipe 2l, with a sup ly pipe 22', coc

22, controlled by three way that when one side of the cylthe other side The cocks 23 23, 23, so inder is opened to the pressure, will be opened to the exhaust.

. B0 body, herein shown as a are connected by a link 24, which extends on each side to the side ofthe car, to permit convenient operation.

. In order to move and turn'the car body, the latter, through the end ofthe yoke 7, is connected to move to and fro and tilt with vthe cylinder 15. Tothis end, the inner side of the cylinder 15 carries a hollow box 2G,

into which projects the adjacent endoi` yoke 7 and turns, as in a trunnio'n in a block 27 mounted to slide in the box 26 longitudinally voi the cylinder. It will thus be seen that if theblock 27 is locked to the cylinden'whenmoves, the gears 11 will roll on the racks l10, thus moving the car body bodily in a lateral 'direction and atthe same time turning it, the end of yoke 7 turn- 28`is a key passing through slots in the upi er and lower faces of box 26-for holdin@ t e lock 27 at either end of the box 26. nasmuchas it is desirable to dump the car body on both sides ofthe car frame, means is provided for. movin the cylinder independently ofthe car body first withdrawing the key from one side of t e block, and reinsertinrJr it on the other side after moving 'the cylin, er and thereby holding the block 'att-he ,other end of box 26. .i In this connection it should be understoodfthat. the stationary piston 19 is at about the middle of the car frame, and that the cylinder 15 and the car body when connectedLmove in the same direction.

CII

Thus, if the car is to dump on the left, the cylinder will move to the left from its extreme right hand position, the block 27 being at the left 'end ot box 26, and the cylinder and car body will both move to the right in returning. 1f now it be-desired to dump on the right, by withdrawing the key 28, the cylinder can move independently of the body until the block 27 strikes the right end of box 26, whereupon by inserting the key to hold the block, and admitting fluid pressure on the right side of piston 19, the car will dump to the right. Preferably, there will be a single key and slots in the box leaving a space on either side equal to the width of the block 27.

In dumping cars of this type, after the heavy massis once in motion, a fluid check prevents teo rapid motion, and permits control, but as the car body nears thefouter end of its dumping stroke, its speed can beincreased somewhat without danger, and thereby the car body ysto pcd with sufficient jar to dislodge the skul from within the ot 6.. p 30 re resents a fluid checking cylinder preferab y cast integrally with the power cylinder 15, and moving therewith, and containing a stationary piston 32 mounted on a rod 33'carried by the pedestal frame.

34 is a by-pass carried by cylinder 30 and connecting the opposite sides of piston 32, and 35 is a controlling cock therein. The cylinder 30 will preferably be filled with a fluid, such as oil, and by adjusting the cock 35, the velocity of flow, and thus the inomentum of the moving car body can be readily controlled independently of the power controlling valves. lf the cock 35 be shut, the carfbody will be locked at any point against movement,and by nearly closing it, the momentum can be checked without straining any of the parts. Then the car is not being dumped, it is prepared to lock the body by means of screws 36 carried by the ends of the cylinder casting and engaging one or the other of notches 37 in the ends of the lower cylinder guide 16, according to which side the cylinder is en. As long as the cylinder is locked the car body cannot move.

Each end of the checking cylinder 30 is provided with an auxiliary ley-pass 33, containing a needle valve cock 39, and operating handle 40 for opening and closing the' passage 38. On the outward movement, it will be seen that the outer auxiliary by-pass 38 will be ino erative until after the piston 32 has crossed the inner end -of the byfpass, whereupon an increased iiow of oil is er-` mitted and thereby greater s eed of the car bodyo Thus the car-body w51 come to rest the 'car body, o

at the dumped position with a shock, deter"- mined by the opening of valve 39, and thereby the skull loosened and discharged.` Suitable abutments on the under frame will be provided to take the shock successfully. .In moving inwardly, preferably the cocks 39 will be closed, and control had by cock 35, though it will be seenl that by leaving the outer cock 39 open, a quick start may be had; a slower intermediate movement and a quick stop, if desired, in either direction. Ordinarily, the quickened movement outwardly at the end is more to be desired than a quick inward or outward start, or a -quickened movement at the inner end. y l

It will be understood that my invention may be applied to a structure wherein leakage past the checking piston, or through it, takes the place of the by-pass 34, vand securing the same acceleration at the desired end or ends.

Frein the foregoing description, the operation ofthe car will be understood, and it will be seen that by these improvements, a dumping car is provided which can be readily controlled by means of the fluid check to have a-faster movement at the ends than at the intermediate portion of the stroke.

The form of the car body may be varied as desired, from the form herein shown, and the other details'of construction may also be changed, without departure from the invention, which is not to be limited to the specil-lc form described.
