DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 223,922, dated January 27, 1880. Application filed June 7, 1879.

Be it known that I, JOHN JONES, of Lakeville, county of Sonoma, and State of California, have invented an Improved Dumping- Oar; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to an improved dumping-car; and my improvements consist in the construction of two separate boxes or receptacles, one of which discharges at the center and the other at the side, these boxes being so arranged as to be either dumped by hand or by the power of the locomotive, as desired, or

both at the same time or separately.

It further consists in providing a centrallyplaced scraper between the rear wheels, which will properly spread the ballast dumped from the centrally-discharging car, sloping it from the center outwardly, as require I It also consists of certain details of construction in the parts for operating the dumpingboxes, as is more fully described in the accompanying drawings, in which- Figures 1 and 2 are views of my dumpingcar. Fig. 3 is a view of the bell-crank-lever coupling. Fig. 4 is a bottom View. Fig. 5 is a transverse section.

The trucks A are connected with the transverse timbers A of the truck-frame in the usual manner, and the transverse timbers are connected by the longitudinal timbers B B. There are three of theselongitudinal timbers -one on each side-the central one, B, being slotted or made in two parts, with a space between, as shown, for the purpose hereinafter described.

Between the center and outer longitudinal timbers on one side is mounted the outwardly or side dumping box, 0, which is hinged, as shown at a, to the timber B, and which has a hinged or swinging side, b, as shown. Between the center and outer longitudinal timbers on the opposite side is mounted the inclined centrally-dischargin g box D, provided with a swinging bottom, a, hinged to the box, as shown, and through which the contents may be dumped between the rails, as hereinafter described.

Under the front platform, E, of the car-frame is placed the sliding frame F. The side portions of this" sliding frame slide in the guides d, and the central connecting-rod 13 passes through the buffer-block and between the two' parts of the central longitudinal timber, B, as shown. On this sliding frame are formed the guides cf, in. which fit the rods 9 h, by which the cars may be dumped, as hereinafter described.

A pin, j, operated by the lever k, passes down through the buffer-block and through a slot or hole in the connecting-rod i, so as to hold the sliding frame in a fixed position. On the end of the connectingrod is a slotted bellcrank lever, 6, provided with a spring, m, for throwing the slot-ted arm down over so as to inclose the bevel-pointed hinged pin a, and hold said pin in an upright position, so as to connect the link of the preceding car. A chain or cord, 0, is secured to the upper end of the bell-crank hinged lever Z, the other end of which swing forward and downward, and free the link by which the preceding car is connected to it. When the pinj is in the slot in the central rod, 2', of the sliding frame the said frame is fixed and cannot move forward, nor will the slotted bell-crank lever be operated to release the link from the pin. When, however, it is desired to allow the sliding frame to perform its office of dumping the boxes, as hereinafter described, then, by moving the lever it up ward, the pin is lifted from the central rod, 45, and the frame may be drawn forward faster than the car moves. In case the frame is drawn too far forward the cord will trip the bellcrank lever, and the preceding car be automatically released by its link sliding off the pin a.

Attached to the inner end of the rod 9, which moves in the guide con the sliding frame, is a chain or cord, 19, said chain or cord being connected with the bar g, which is supported and moves on plates between the two parts of the double or slotted central longitudinal timber,

B, this bar q having a longitudinal motion in the slotted timber. Attached to the lower edge of this sliding bar q are the cords or chains 1", which lead through the oppositelyplaced double pulleys s and over the pulleys t, where the other ends are fastened to the ends of the long arms of the weighted levers u, said levers moving in the slotted timbers joining the central and side longitudinal timbers under the outmtrdly or side dumping box 0, as shown.

On the ends of the short arms of the lever' to are the anti-friction rollers 7;, which impinge on the under sides of the beveled hinged levercatches w, which are hinged on the under inneg side ofthe box, 0. These catches in are hinged, like bell-crank levers, on the under side of the box, and their long arms or outer ends are weighted and beveled off, as shown. The book or catch is formed on the downwardprojecting end, said hook engaging with alug or recess formed in the side of the central longitudinal timber, so as to prevent the box C from tipping down outwardly on its hinges unless said hooks are released. The inner or lower face of this hook is rounded or curved at the angle, so that the anti-friction rollers 12 on the levers a will fit into these curves as the box comes level, so as to force said hook to engage with the lugs or recesses with certainty. By these anti-friction rollers coming flush up against the downward-proj ectin g part of the hook they come a little inside of the pin on which the hook swings, and, the angle being curved, the weight on the outer end of the hook draws that end down behind the rollers and throws the hooked end into the lug or recess.

As the levers a are operated by the cords r, as hereinafter described, the friction-rollers on the ends, impinging in the lever-catches, liberate the hooks from the lugs or recesses in the timbers, and, rolling back on the rear ends .of said hooks, press upward on the under inner sides of the box and tip it over on its hinges.

The hinged side I) of the box is held closed by self-adjusting catches or, which are hinged on the lower side of the box, like levers, the long arms extending back under the box and across over the longitudinal timber B, as shown. The weight of the longer arms of these catches is sufficient to throw the outer hooked end up into contact with the edge of the swinging side and hold it closed. When, however, the box is tipped these long arms come into contact with the edges of the longitudinal timber, their outer hooked ends are depressed, so as to release the side of the car, which swings open on its hinges, and the cow tents slide out beside the track. A weight, y, on the inner under side of the box brings it back to the level again after the load is dumped.

The box D is made with inclined sides, and the load is dumped through the hinged bottom 0, so as to fall between the rails.

The rod it moves in eyes on the side of the longitudinal timber B, its front end moving in the guides f on the sliding frame. At the center of the timber are the pair ofrollers a, and

a cord, I), attached to the rod h, passes between these rollers and under a roller, 0, where it is attached to the weighted bell-crank lever 01, which is pivoted on the outer sloping side of the box. The end of this lever d engages with the beveled or sloping end of a laterallymoving spring-lever catch, 6', which is pivoted on the lower side of thehinged bottom 0. The other end of this spring-lever catch engages with a notched lug, f, so as to hold the bottom closed.

When the rod h is moved in either direction, the cord 1), moving over the rollers, operates the weighted lever 01, so that the other end of said lever will push on the beveled end of the spring-lever 0, moving it laterally, so as to release it from the lug f on the edge of the box, and the bottom thus falls open.

As soon as the contents of the box are discharged, weights g, which are hung on cords h, passing over rollers i, and attached to the corners of the movable bottom, draw the bottom up again to its seat, and the spring-lever catches on the lug and holds the bottom in position, the weighted lever dropping down, so as to again impinge on the said spring-lever, ready to operate it again.

0n the timber or bolster of the rear axle is bolted a bar, j, on which are two more rods, carrying or holding the scraper G, the other end of which is supported on the rods or bars l, which hang from the end of the car frame or platform. This scraper has downward projecting flanges or sides, and is wider at the front than the rear end, as shown. It is placed between the last pair of wheels, and is designed to gather the gravel or ballast which is dumped from the centrally-discharging box, D and draw it toward the center of the track between the rails, so that there will be a slope from the center inwardly.

Passing down through the rear platform is a hand-rod, g, which screws into a hanger, r, on the upper frontend of the scraper, by which the height of the front end of the scraper above the ground is regulated as desired. The scraper is thus rendered adjustable.

Each of the boxes on the car may be dumped automatically as the cars are moving, by means of the sliding frame F, at one and the same time, or separatelygas desired, or they may be dumped by hand.

When it is desired to dump the centrallydischarging car D automatically a pin, m, is pushed through the rod h and guide f, securing said rod to the guide. Then, when the pin j is withdrawn from the rod i of the sliding frame by means of the lever k, and the forward car draws the sliding frame forward, the rod h is also drawn forward. This action draws the cord b over the rollers a c, and operates the bell-crank lever d, movin gthe springlever catch 0, and allows the bottom to fall, so that the load will dump itself, sliding down the inclined sides of the box and falling between the rails. 1

If it is desired to dump the central car by hand, the pin m is removed from the rod h and guide f, and the rod h is drawn toward the rear of the car by means of a cord, n, the rod h performing the same duty of operating the levers and operating the bottom, whether drawn in onedirection or the other, its cord 11 leadingover one of the rollers a in either case.

To dump the side discharge car orbox am tomatically a pin, 0, is passed through the rod g and guide 0 on the sliding frame, so as to fasten said rod to the frame. Then when the pin j is withdrawn from the rod 2' of the sliding frame by means of the lever 7c, and the forward car draws the sliding frame forward, the rod 9 is also drawn forward. This action draws the cord 12, attached to the bar q, forward, moving said bar also forward. The cords or chains r on said bar q, leading over the pulleys s and t, operate the weighted 1evers a, which release the catches w and tilt the box 0 upon its hinges, and the self-operating catches as, when they strike 011 the longitudinal timbers, release the swinging side of the box and allow the load to slide out.

' lfit is desired to dump this box by hand, the pin 0 is withdrawn from the rod 9 and guide a, and a cord, 19, attached to the opposite end of the bar q, will move said bar in the opposite direction, and the same dumping action is accomplished.

The cords or chains '1", leading over thepulleys s and t, will operate the levers whether the bar is drawn in one direction or the other, and the same bar operates both sets of levers u and catches w, they being constructed exactly alike.

It will be evident that either centrally or outwardly discharging box maybe dumped at once, or either separately, as desired, and they can bedumped by hand or by power. The power of the locomotive in moving the car is partly expended in drawing the sliding frame forward when the pin is drawn out, as described, and all labor-in dumpingis obviated.

In case there is too much strain on the side rods and cords the cars are separated by the coupling-pin n being released, as herein de scribed.

It will be seen that the position of the two boxes may be reversed on alternate cars by reversing the position of the scraper and sliding frame as to the end on which they are placed, and the ballast thus be evenly dis tributed. With the ears constructed in this manner ballaslin g railroad-tracks may be done quickly and conveniently. The scraper draws the centrally-discharged load away from the rails, sloping it from the center outwardly, and very little hand labor will make an even distribution.

The whole operation of dumping and scrap in g may be performed while the train is moving along, both the inside and the outside of the track being ballasted. When filling in embanknlents, &c., where the track is on trestles, the scraper may be dispensed with, but the loads will be dumped within close proximity to the line of the track.

In some cases it may be preferable to have the central and side dumping boxes mounted on separate cars, where all the dumping is needed either in the center or on the side of the tracks. The levers and operating -rods may then be applied to the cars separately, but in' the same general manner as herein described.

Ordinarily it will only be necessary to have one of the sliding frames on the first car of a train, and the cords np can then connect from the rear end of one set of the operating-rods to the front of the rods on the next following car. Then, when the sliding frame is drawn forward, as herein described, all the operatingrods on the succeedingcars will be moved forward and the levers will dump the cars. The hand-cords n p then form connecting-links between the sets of rods on the separate cars, so as to make the operating-rods act in unison and dump the boxes. These rods will operate when the train is at a standstill, provided the pin is lifted and the sliding frame drawn ahead by the engine. Where only one or two cars are to be dumped it is sometimes preferable to dump by hand; but in a long train I will connect the cords n p with the rods 9 h of the following car, and the sliding frame will dump the boxes in the whole train.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
