ST fl/ZZ wil/0m, t may con/cern,.-

Be it known that I, MATTHEW VAN WORM- ER, of Melrose, in the State of Massachusetts,

have invented certain new and useful Im-4 sills with the transom, braces, small iron stringers, and inclined blocks; to combining with the rocker a pendent slotted bar working on a fixed pin; to combining with the .rocker peculiarly-constructed stirrups pivoted thereon, and provided with cross-bars and a horn or horns on the truck; to devices for actuating these stirrups; to combining certain braces on the car-body with certain blocks on the truck-bolster; to combining with the arch-bar of the truck inclined blocks on the transom; to the combination, with a system of toothed wheels and their car-tilting chain, of a peculiar system of leversl and rods l'or pushing over the rocker; to the combination, with the transoms of the car-body, of metal hangers secured to their ends and supporting the outside sills; to the combination, with end sill and with the bumper, of a hinged platform adapted to be held up in an upright position', to a special combination, with the center crosssill and outside sills, of certain blocks and middle posts and their' fastening-yokes; to the combination, with the middle posts and with the ear-bed, of an iron brace secured to the posts and floor, to a special construction and arrangement for hanging the swinging gates to a novel means for automatically latching and unlatching these gates; to the means l'or operating the chain and leversfor tilting the car, and to other devices more fully hereinafter explained.

Figure l. is a partial side elevation of a dump-car, showing some ofmy improvements; Fig. 2, a plan of the car-traine, a portion of the frame being broken away; Fig, 3, a view 'spending parts of the piece 3.

showing a cross-section of the car-body to illustrate the dumping mechanism; Fig. 1 1-, a central cross-section through the body of the car; Fig. 5, an end view 5 Figs. 6 to 1G, inelusive, details.

The top bolster, l, of the truck is combined with Ya center plate, having integral with it an upwardly-entending projection of sugar-loaf form, in con'lbination with the rocker composed of two curved bars, 2, about square in cross-section, and separated by a wooden arched piece, 3, projecting partly through the space between them, a narrow metal piece, 4, having holes 4t* for pins 5, being placed 011 the convex face of arch 3 and between the bars 3. The pieces or plates Lt reach to the opening or socket 7, left for the sugar-loafshaped projection 6, which keeps the rocker and the car-body from shifting out of place laterally, and the bars 2 prevent any endwise movement and permit this Sugarloaf-shaped projection (as strong pins) to draw the load, thus serving the duty of a center bearing77 on an ordinary car. The bolts 8 pass through the bars 2 and the piece 3, and hold them firmly together, as il" they were one piece. The plates 4 are bolted (see Fig. 9) to and through the part 3.

10 10 are the draft-timbers, which are fastened at their ends to the cross-sills, and they are also bolted to the middle stringers, l2, which rest directly on them, the bolts running through the transoms 13 andI down through the rockers. These timbers are set into the arched piece 3, and are notched or recessed, as shown at 3*, to rest solidly upon corre- The lower faces of these draft-timbers rest directly on the top edges of the metal hars 2. rihis gives great strength to the end of the car, and holds the draft-timbers firmly. These draft-timbers extend from the end ot' the car through the rocker. The stringcrs l-'lrest directly on the horizontal ends of the rocker, and these stringers are placed nearer than customary to the center of the car for this purpose, and so that the outer sides of the stringers need not be ent oil and weakened to make room i'or the arch of the rocker. The stringers are thus left in their l'nll strength.

l5 are iron stringers to strengthen the lloor in IOO the intermediate space between the outside sills and the stringers 14. yThese stringers are each composed of two parallel metal strips placed edgewise, and with an open space, 15', between them, except where they are connected to the center or other bolsters or end sills, and at those points iron blocks 152 are placed between them and bolted to them, and bolts 153 pass thro ugh the bolsters and through these blocks and hold the whole to place.

Braces 16 are to strengthen or support the transoms 13. Bolts 17 connect the braces with the transoms, and these braces are let a little into the side ofthe stringer,as at 18, for the purpose of strengthening it, when in dumping it strikes a block, 19, on top of the bolster l. These blocks 19 are between the wheels, so that when the dumping takes place this blow tends to hold the truck down, while in former construetions,where the blow is upon the arch-bar 2O at a point outside the wheels, the tendency is to tip and capsize lthe truck. The

reduced end 21 ofthe braces'16 rests under the stringer 14 and between the adjacent bars of the rocker, and is bolted by a bolt extending up through the stringer 14 and transom 13.

23 23 are inclined blocks (metal or wood) resting against the iron stringers 15 and against the transom, and bolted up through the transom for the purpose of strengthening the transom, and the inclined faces of these blocks, when the car is dumped, rest squarely on the arch-bar 20, the corners of the bolster being cut off topermit a sufficient tilting, and to permit these inclines so to rest on the archbar. The stringers 14 being set nearer the car center than usual,in order to rest squarely on the horizontal ends of the rocker, leave a large space between these stringers and the outside sills, 48. The intermediate stringers, 15, between these sills must be of much less depth than the other sills to avoid coming in contact either with the wheel or with the bolster 1. I therefore make them of iron instead of wood, and thus get all the requisite strength without their interfering in the least with tilting the ear to its utmost limit.

24 is a slotted metal bar bolted at its upper end loosely on the rocker. A pin or bolt, 25, secured in the bolstervl, projects through this slot. Vhen the ear is fully tilted, (no matter how violently,`) the terminus or end of this slot is held by this bolt 25, and renders it impossible for the car-body to leave the truck, while, as above stated, the blow or concussion in dumping the brace 16 on block 19, tending to keep the car on the track, aids in accomplishing this result..

In my present construction I do not use what are known as side bearings, but I employ instead the following devices for holding the car in position when under way or in transit.

26 is a hanging stirrup, pivoted at its upper end to the stringer 14. It has two cross-bars, 27 28.

29 is a hornor tongue iiXed to the bolster stringers.

1,'and adapted to project into and through the stirrup and to hold the same in its vertical position.

c Inasmueh as the trucks are shown as turn-y ing on centers, it 1s advisable sometimes, if

stirrup to hug more closely upon its own tongue. The tongues 29 should be inclined atl their two sides and at their top, but be hori zontal at the bottoms, so that the stirrups may (when not purposely set free) hold their'p'osition thereon, and may also, when descending, allow the cross-bars 27 and 2S, respectively, to ride on the inclines to be set free. The lower ends of the stirrups are adapted to catch against the horizontal or under side ofthe projecting tongues or horns 29; but when the car-bed is strictly horizontal these lower ends are not in direct contact with the tongues, there being a little space or play between them, so as to allow the bed a little requisite movement or play, that it may not be held too rigidly, and also the more easily to let the stirrup free itself when required. Vhen the ear is partly tilted and thetongue shall have entered between the bars 27 and 23, and in ease part only of the load has been dumped, the bar 27 will hold the carin position and prevent its going back and the risk of breaking the mechanism. Upon further tilting, the bar 28 passes, frees the stirrup, and the tongue may then enter. l

A shaft, 30, supported in proper bearings, extends from one end of the car to and beyond the rst bolster, 31. Near the inner end of this shaft is a toothed pulley, 32, and at its inner end is another toothed pulley, 33, and near its outer end another toothed pulley, 34. This shaft and its pulleys receive motion from a linked endless chain, 35, which passes around pulley 34 and a toothed pulley, A36, on the shaft of a cog-wheel, 37, which is driven by a small pinion or cog wheel, 3S, operated by a hand-crank, 39, giving great power by this series of gears. around pulley 32, and up' and over the toothed guide-pulleys 41 41, 42 42, and 43 43, and thence, crossing itself, its ends are connected, respectively to the ends of the levers 44.

It will be evident that the cog-wheels 37 and 39 may be dispensed with and a crank like 39, but longer, to give more power, may be applied directly to the shaft of the toothed or sprocket pulley 36. Pulleys 41 and 42 are respectively hung in eyebolts which are secured to plates 45, these plates being bolted to the respective stringers 12. Pulleys 43 are each in an eyebolt extending throughthese The levers 44 are pivoted to the bolster 1, and the rods 46, pivoted to the rocker, are also connected by a pivot to the levers 44. When the car is tilted7 the chain A linked chain, 40, passes I OC being assumed to be always taut, as it is pulled up it pulls upward the rod 46 at-that side of the rocker, and this rod pushes up the rocker at that side,while the other side of the rocker pushes down the other rod 46, which then pushes the rod 44, to which the chain is attached, and keeps the chain taut.

The transoms 13 do notextend over across all the top of the outside sills S6, but rest upon the same, and these sills are held up to these transoms by metal hangers 47 ,which are bolted to and through the transoms, and the sills are bolted to the hangers. It will be evident that the form of these hangers may be varied as desired.

49 and 50 are toothed pulleys over which a chain, passing under the toothed pulley 33, is conducted.. This chain is of sufficient length for all the traverse it requires, and its ends are connected to rods or chains 51, which run lengthwise of the car beneat-h its bed, and their other ends are connected near the other truck of the carto other chains, 52 53, which pass under toothed pulleys 54 55, and thence over pulleys 41* 42% which are similar to pulleys 41 and 42, thence over the other pulleys, like 43, not necessary to be repeated, and thence to the ends of levers like those shown at 44 and which are connected with the truck and with the rocker in the manner already described.

A brake-staff, 56, (on each side of the car,) with appropriate handle, 57, serves to pull the stirrups off from the horns 29, and by so doing relieve the car and allow it to dump. 5S is an ordinary brake-wheel to prevent the 'turning back of the brakestaff', and it should have the usual pawl for this purpose. To this staff are connected chains 59, which pass around a pulley, 60, one chain winding in one direetion on the staff 56 and the other winding on it in the reverse direction. Both these chains also are connected to a slide-rod, 61, which operates the stirrups on the opposite end of the ear. Chains62 and 62* connect this rodwith the stirrups, as shown, those marked 62* passing over pulleys 63 on the outside of stringers 64. Stops 65 65 serve to limit the endwise movements of this sliderod. These devices may, if desired, be placed on the inside of the stringers` instead of on the outside, but I prefer them on the outside.

The horns 29 may not only be bolted to the side of the `bolster 1 by as many bolts as may be desired, but in some cases I also make them with their back plate or base extending downward, then horizontally a short distance under the bolster 1, and then upward, project ing a short distance into the bolster7 as shown at 66.

69 is a hinged platform for the operator. It is furnished with one or more upwardlyproljecting pins to give him asecureioothold, and vit may be hinged either to the erosssill or to the floor, and when in use it may rest both on the end sill and'on the bumper 68; but, inasmuch as the platform needs to be broader than the bumper, it may sometimes be desirable to place brackets or supports on the end sills at each side of the bumper to give a iirmer support to this platform. A great advantage incident to hinging the platform when it is concessed, as shown at 71, so as actually to make the carrying capacity as great or greater than that of ordinary freight-ears. The notch or recess 71 also gives asupport to the end posts, which thus rest on the end sills, 67 g; and this arrangement also permits the bolting of these parts to these end sills, G7, as well as to the outside sills, 86. By hinging the platform on the ear it may be raised and held up out ol the way of any one coming between two ears to couple or uncouple them, or for any other purpose.

The end pieces, 77, of the gates or doors, the central side posts, 73,.as also the end posts7 70, on which the doors swing, are provided with eyebolts, the eyes being on the outside ofthe posts and ofthe doors, the bolts 75 passing through these eyes, and with them coustituting hinges. This permits the doors to givev a quicker, easier, and wider opening when the car is tilted than they could have it the doors were hung at points farther inward; and it entirely avoids putting the hingingbolt through the posts, and thus weakening them. Metal plates 76 should preferably be employed, as shown, and through which the eyebolts pass. Instead of the eyebolts, plates having eyes to receive the bolt 75 may be sub stituted, and such plates may be bolted to the outside ofthe posts and doors.

The lower end of each ot' the middle posts, 73,is slotted to straddle the outside sill, 86, as seen in Fig. 4. An iron yoke, 78, spans the post at its bot-tom. rIhe legs of this yoke pass through the sill S6, and at its ends receive a connecting-bar, 79, which is tightened and held to place by nuts 80. l

I use in my present construction a central cross-sill, 8l, of greater depth than theusual cross-sills, S3 83, and under all three of these cross-sills pass the truss-rods S2 82,which bear on all these sills. The advantages of this are that the sill 8l, being central, gives a support to the central or weakest part ofthe body; next, beingsome inches deeper than the sills 83, it has greater strength than they; and, lastly, as the lowest point of thel t-russ-rod 82 at its bend is immediately under this sill 8l, the tension or strain oi' this rod is exerted upward directly against the bottom of this sill.

Blocks 84 84 are placed between the outside sills, 12, and the stringers 64, abutting against rio both. They are recessed on the top,as shown, to receive the iron stringers 15,'and the inner part of the bottom of the posts 73, thus serving to prevent the stringers 15 from springing either downward or sidewise, and to prevent the top of the posts from springing outward.

rlhe posts 73 may also, if desired, be further braced by an iron brace, 85, which laps the outside of these posts at their tops, extends over these tops and then down to the car-licor, where it is bolted through the stringers 64 64, asshown.

rlhe iron stringers 15 15, which, as before stated, are .each composed of two parallel pieces, having blocks between them at intervals, are secured to the transom and door by bolts, as shown.

The outside longitudinal sills of the car are shown at 86 as let into rabbets 81* made in the ends of sill 81. v

All the wheels over which the chains pass are similarly constructed for linked chains. Fig. 12 shows an edge view of one of these wheels with the chain thereon. The wheel has not only the usual series of pins, 87, for entering the links, but has in addition other projections, 88, placed in couples and near together to admit the thickness but not the breadth of a link between them. These projections form positive stops against the slipping of the chain in case one of the pins 87 should break with the strain, because the space between each pair of projections 88 is much less than the breadth of adjacent flat link 89, which therefore cannot pass them.

My latch for automatically fastening and f unfastening the swing-doors of the cars is made as follows: At the bottom of the gate I secure sition.

one or more slotted iron plates, 90, which are turned up, as shown at 91, behind the gate, to relieve their fastening bolts from strain. Braces 93, secured to the inside of the gates, rest at their bottom ends upon these plates, and sustain them firmly against any upward pressure from any source. The plates 90 also incline upward at their inner side, to insure their passing the bolt when the gates swing down to shut. rIhe bolts 94 are also inclined at their upper ends to permit the gate-plates 90, when the gate swings down for closing, to readily ride past them and force them back a little until the slot in the plate coincideswith the end of the bolt, to permit an automatic latching. A keeper plate, 95, is secured against the inside of the outside sills, and through it the bolt 94 plays and is held in po- Each of these bolts is connected to the arm 96 by means of a pin slidingin a slot, 96:5, formed in the outer end of an arm 96, connected with a journaledl bar, 97 suspended or sustained from the under side of the car-licor.

' A downwardly-inclined iron arm, 98, is firmly secured to this bar 97, and on tilting the car this arm strikes or comes in contact with the arch-bar 20 of the car-truck, and this lifts this arm 98, rocks the bar 97 on its journals, lowe ers the outer ends of two arms 96,V and withdraws the bolts 94. Vv' hen the car is resuming its horizontal position, the gates swing back to place and the weight of the arms 98 again forces the latch-bolts 94 into the slots of the plates. All these devices for automatically latching and unlatching the gates or doors, being on the inside of the car-body or of the gates, are free from being damaged or disarranged by anything outside, whether the car is in motion or not;

rlhe arms 96 maybe of any/number, (one or more,) as desired. We have shown two, attached to the same bar, 97, adapted for two latches 90 on each gate.

All the gears and chains, excepting the whole of large cog-wheel and its driver, are behind the end sill of the car-body.
