Toll whom 'it may concern and useful Improvements in Dumping-Gars;

and I do `hereby declare that the following is a full, clem-,and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying thereon, which form a part of this specitication.

My present invention is an improvement on fthe inventions setforth in the following-named patents issued vto me, namely, No. 193,101, dated July 17, 1877; No. 199,761, dated Jannary 29, 1878, and No. 200,813, dated February 26, 1878; and it relates to the construction of the car-bed; to the transoms; to the construction of the rockersA `and means whereby the car, after dumping,ushall right itself up again;

to a device for preventing the. separation of the car-bed from thetrucks; to the mechanism and uni'asteningthe. doors of the car; to the construction of thedoors to the end posts and i the means `for fastening the same to the carbed; kto thevcentcr posts and the means for? fastening them .to the car-bed; to thelside bearings and their application, so as to keep thev earfbcdin position and to prevent undue frictionwhile the car is movingA around curves of the track; in combining with the draw-bar a rocker, whereby the dumping may take place .v with the ordinary draw-bar without need of" uncoupling the car from the other cars of the train; in an improved brake mechanism; in a special construction of clutch-pulley with grooves and sockets`- adapted to receive and tion, ot'V guide-rollers'for the chains; in combiningthe shaft oftthe clutch-coupling pulleys and their chain and its guide-pulleys with a` worm-gear or screw-lever for operating the same, and in other particulars hereinafter set forth. l l

In the drawings, Figure 1 is kan elevation of my improved dump-car; Fig. 2, a bottom view with one truck removed Fig. 3, a cross-section through line 'a2 of Fig. 2,; Fig'. 4, a top view of one of the trucks; Fig. 5, a plan ofthe couplers, and'Fig. 6 a sectionV through y y; Figs. 7 and 8, details of the draw-head and its n rocker; Figs. 9 and 10, details, showing the drawings, and to letters of reference marked side bearings; Figs. 11 and 12, brake mechanisrn;\Fig.'13, partial top view, parts being l broken away, showing the coupler-pulleys and their connections; Fig. 14:, fragment enlarged of convex stationary bed; Figs. l5, 16,17 18, and 19, details.

Y. 0f the timbers of the car-frame, 1 lnrepresent crosssills or headers extending .from the longitudinal sills 2 and 5, and framed or` se- :cured into the same. 3 ande represent shorter sills framed into'the cross-sill or header 1, and

not as long as the outside sills, 6 7, orthe sills 2 5, the objects of making them shorter being for,` the purpose of giving space or room for-.the

. worm and gear of the screw-lever or other and other iron bars or Wood transoms, ci, passing underneath the inside sills of the car and passing up in the shape of a bracev between the respective outside sills, 6 7, and the sills 2 5, are fastened to the transom 8, making a sufcient spacebetween the lower sides'of these transom-braces a and the truck -timbers or truck-irons to give the car-bed more and am- Vple dumping-room without coming in contact with such timbers or irons or with the oilboxes when discharging any material from the car. These transoms or braces a also make the construction strong and safe.

The rockers and their arched beds are such IOO that after dumping the car-bed will right-itself up again, and they are constructed asfollows,

9 representing the rockers, their stationary convex beds being shown at 10: Each may be all of iron, or of iron and wood. The rockers 9 have each a short central downwardlyprojecting stud or boss, b, which may be of ball shape, if desired, and also a series of stout strong cogs, c c, on both sides of this stud, and the convex beds (see Figs. 3 and 14) have each a central shallow socket, c', to receive the stud or boss b, and also a series of sockets, c2 c", adapted to receive the cogs c c, the object of this being that when the car is turned or dumped they will prevent the car-bed from getting out of position, and at the same time permit the tilting of the bed far enough over and to a degree of pitch suiiicient to discharge coal or other material without the risk of coming in contact with either the trucks, truck-irons, oil-boxes, or wheels, and also to permit the car -to right itself up after dumping. rlhe car or car-bed will automatically right itself after dumping, because when it is tilted or turned over to dump, and is left free to return by disengagement of the V- shaped couplings on the shaft, (or shafts,) 12, hereinafter described, the fulcruin or bearing-point of the rocker is no longer at the boss b and its central socket, but has been shifted to one or more of the cogs and to their sockets, thus giving a long leverage for that side of the car or bed which is for the time being raised up, and this causes that side to fall by its own weight till the car is again level. It will be seen that any mechanical equivalent of these sockets, teeth, or cogs, and boss which will allow the same action and result may be substituted for them. A bar of iron or wood represented at 11 is designed to hold the car-bed from separating from the trucks while the car is in transit or motion. It is bolted or fastened to the truck-timber or to the lower convex bed, l0, and extends upward to be attached to eitherthe upper rocker, 9, or to the car-bed, or to a cross-sill, and is provided with a bolt, for connecting it to such part, or to any iron or wood fastened thereto.

Ashaft, (or shafts, if desired,) marked 12, runs lengthwise of the car under its floor, either its full length or a suicient distance for receiving at its end or ends coupling-pulleys c c', having V-shaped teeth on their adjacent sides, for engaging with each other. On this shaft 12 (if but one be used) are affixed permanently one near each end, and to revolve with it, two clutches, e, having V-shaped teeth, as shown, designed each to be engaged or disengaged at will from its fellow, which is provided with similar V-shaped teeth, and placed loosely upon the shaft, and adapted to be shifted in or out of engagement with the fixed clutch e. (See enlarge views, Figs. 5 and 12.) This coupling apparatus is to be located beneath the transom S, so that the latter shall in no wise interfere with its freerevolution. A chain, f, Figs. 1 and 2, passing over and clinging to the loose pulley e', (the particular construction of which pulley lwill be hereinafter fully dcscribed,) and wind- Vrun in appropriate guides or staples m.

ing partly around said pulley, passes thence under guide-pulleys g g, adjustable, if desired, secured to the rocker or to the timbers of the car-bed. This chain also passes under guidepulleys h h, (see Figs. 1, 3, and 17,) attached, respectively, to the opposite ends of the trucktimbers or frame; thence the ends of the chain respectively pass up to and are fastened upon the car-bed, or upon the outside sills, 6 7, or to the car-floor.

For the purpose of applying the pulleys h h to the outer ends of the truck-timbers, so as not to interfere with the proper action of the car-springs, I fasten to the end of the under truck-timber a stra-p or bar, t', (see Fig. 17,) of wood or iron, and connect it to the upper trucktimber by bolts extending into or through such truck-timber and through a slot in said strap or bar i, such slot allowing the springs between the two truck-timbers to work the same as though said strap or bar were not there. The slot may be in either end of the bar i'. Another strap or bar, i', of iron, (or of wood,) is bolted to the'lower end of the bar i, (or to the truck-timber, to which it is firmly attached,) and extends outward sufficiently to admit the pulley h between the bars i and i', the axis or journal of said pulley 7: being supported by the two straps t' i.

I will now describe the manner and the means of fastening and unfastening the doors automatically.

A bar or rod of iron, 15, fastened or suspended to the outside sills respectively of the car, have thereon one or more dogs or levers, 7c, (see Fig. 3,) and to the outer ends of such levers are pivoted one or more upright slides or latches, Z, adapted to extend a little above the ioor of the car, sufficient to catch, latch, and hold down the swinging doors 16,which latches The levers 7c are so constructed that when the car is being dumped their long arms will come in contact with or strike the truck-timber or truckirons at the appropriate time and unlatch the doors 16. Each latch Lis provided with a hole, in which a pin, n, may be inserted to lock them when desired. When these pins are removed the latches are ready for their automatic action upon tilting the car, as above stated.

Each door 16 (see Fig. 1) is a batten-door, mortised in timbers or iron 0 at each end, and swinging on pivots at their upper ends. lhese doors are also supplied with and strengthened by metal cross-bars or straps p secured thereto, the lower ends of which are so beveled or turned under at an incline as to allow them readily to pass the upper beveled ends of the latches l in the act of closing the doors. The weight of the levers k tends to throw up the latches l and to automatically fasten the doors when they shall have passed the latches. One or more straps, q, of wood or iron, fastened on the outside of the door, and extending below its lower line, serves to prevent the door from swinging too far in. The door is also provided IOC IIO

t itlandrholding it properlytoplace.. The upright end posts, 17, of' the carand with one or more trussrods, out, or both, for. the purpose o their connections are nsfollows: They rest, respectively,juponthe outside sills, 6 7, and ex-` tend down on the side thereof a sufiicient distance to admit of being strongly secured theretobybolts or otherwise,fand exteudfar enough above thedoor's to permit the same to be hinged or attached thereto. Said posts 17 are grooved or recessed on their inner corners (see Figl)` to treceive the end board of the car, so as to leave? the inner face of said board or vplank ilushor evenwith theinside ot' the post-therebypreventing any obstruction when unloading, and also to make the car more hrm and strong. A rod',..s, of metal or wood, extends across the end `of thecar and through both these posts to hold them and the end plank or board, t, rmly in their places. There is also an iron or Wooden brace, u, extending vfrom i each post to the end sillor door, to aid in bracing and' holding said post 17 to its place. The

upright center posts, 18, also restand are secured,r'espectively, upon the outside and top of asill, and each is further securedv by a metal plate, uf, which extends down andisfastened i to the inside of the outside sills of the car,` as

seen in Fig. 16. y A metal rod, v, passes through both these opposite center posts, 18 18, under y the floor and above thesills, and is tightened 1 an end kof the rocker.

byappropriate nuts or equivalent means -for firmly holding the posts in place. t

1 The side bearings `for holding the car and keeping it in position are represented `at 19 in Fig. Saudin an enlargedview in Figs. 9 and 1 10,a'nd are as follows: They severally consist of` a barV of iron or wood` adapted to rest on the 'truck-tim ber, and exten din g upward and movably securedftotherocker` or to the sills or trausoms or `ioor of the car. Through a hole, wfhaving a slot-or keyway, y, in the upper cudllof each .side1bearing, passes a shaftor bolt, z, with a key or pin, a2, thereon. Thisl shaft is secured to the car as above named. It is represented in the drawings as attached to This slot y allows the side bearing to play at its upper end, and thus preventthat friction which it would otherwise have if compelled to travel or move rigidly upon the truck-tim ber when the car is moving around curves. y

The outer end of the shaft or bolt #receives bearingV to be moved `by appropriate connec- V tions,extendingupward, and connecting with 1' lr eitherinsideor 1 strengthening brakes. Y i pended by links k2 from springing or yieldjingistraps l2, secured upon the truck-beams.

. be held.

l0n the-under side ofeach draw-bary 20 is an arched orfcurv'e'd rocker, 20*, the object of which is to permit the car to be tiltedfor dump- 4ing or otherwise without theneed of uncoup'- yling anycar fromthe other cars of thetrain. :(Seev Figs. 7 andf8.) This rocker may rest on a curved bed, as shown in Fig. 8.

A I will now describe my improved brake mechanism, consisting of a combination of levers, chains, and pulleys,-as follows, referring more particularly to FigsA aud 17 A bar,2l, .of metal or wood, attached to the truck-tim- :ber by anarm, .22,and bolts or screws, is also attached to the brake rod-or bar f2 by'au arm, 23, and bolts or screws. The two brake-bars of each truck act coincidently upon the inner perimeter of all the wheels of each truck bymeans ofthe following connections: This bar or lever 21,which is connected to and immediately operates one ofthe brake-bars, and which,x

as above stated, is fulcrumed upon the lower truck-beam, is also connectedby means of a rod orbar,'i2, with one end of a lever, j, at the opposite side of said truck-beam, the other end of said lever connecting with the other brakebar g2, which acts upon the other two wheels l ot the same truck, thus giving a movementin opposite directions at the same time to the two brake-bars.` Provision is 'made for adjusting the throw of the levers which actuate the Thebrakes and their bars are sus- This affords a yielding and play to meet vary- `ing exigencies and a self-adaptation to the curvature of the wheel.

To 'the upper end of bar 21 (see Figs. 11 and 12)is attached a chain, (or a rod,) .which connects wit-h a lever, m2, one endofsaid lever being fastened to the sill or floor of the car, as

shown at n, and the other end being connected to a chain, (or rod,) 02, running in a 'direction lengthwise of the car, such chain passing, around a pulley, p2, on or near the end of the car, and fastened at its extremity to an upright hand-lever, which lever is pivoted to the sill or below the sill ot' the car. By operiating this lever the brakes are vbrought into 1 action, and the lever may be held to any de sired position by means of a rackwor ratchet,

IOO

r2, with the teeth of which it may engage and The loose coupling-pulley e has cavities on i its periphery precisely adapted toreceive and an arm, b3, securedto itby a pin orlscrewfor thepurpose of permitting the said shaftandhold positively therein the successive links Vof the chain f. These cavities may be described as fol1ows,in general terms: A series of ovalz shaped depressions orsockets, s2, (see Figs. 5 j and 6,) to receive those links which lie hat,

tively and without any chance of slipping pull the chain in the direction of its revolution and thereby tilt the car. rEhe chain being properly applied in the rstinstance with sufficient slack at its opposite ends to permit the greatest degree of tilting ever required, this proper relation is always under control. The chain is thus always self-holding to its pulley and can never slip, although the chain is, as it needs to be for this purpose, a loose one.

. For connecting and disconnectin g these couplers c c there is an annular groove, c", around the periphery of the loose pulley c', into which proiects a pin, upon a shifting-lever, 24, (see Fig. 13,) pivoted to a rod, u2, extending lengthwise of the car, for operating both couplings, if desired, said rod being actuated by means of a hand-lever at the end of the cnror other convenient place. YVhen, by means of this lever, the couplings are disengaged or un coupled the pulley c may revolve suddenly, as a loose pulley, in order to allow the ear-bed to dischargeits load itself, when it will come back or return of itself to its uprightposition. When the coupling-pulleys are coupled or engaged then the car maybe tilted slowly. This ca pacity for sudden dumping is important when clay, damp coal, or other damp or adhesive material constitutes the load, so as to discharge it with a jar or thud but with other materials which might be damaged by such jars or shocks, or when it is desired to deliver' gradually, the V-conplings, when in engagement, afford full control to tilt the car as far or as slowly as may be advisable.

The guide-pulleys g for the chain f are hexagonal on their peripheries, thus presenting six fiat surfaces of a size adapted to the atlying links of the chain, and a peripheral groove, x2, adapts them for receiving the intermediateoredgewise-lyinglinks. (Seeenlarged view,l `i'g. 19.) Thus these pulleys fit all the surface of the chain and prevent its getting off. They maybe danged, also, if desired. Instead of being hexagonal, these pulleys may have eight or more peripheral faces. The pulleys lt are circular, but with an annular groove to receive the edges of alternate links of the chain.

I claim-- l. The car-bed as made, with the cross-sills and headers 1 1 extended from the longitudinal sills 2 5, and which reach from end to end ofthe car, and framed or fastened thereon, and with the shorter longitudinal sills 3 4, framed into the headers 1 1, and with the outside sills, 6 7, the construction affording space at the ends of the car and between the sills 2 5 for the worm and gear or machinery which operates the dumping mechanism, and am ple clear space at the sides for dumping, and all without weakening the car-bed.
