columna-CAR.

. SPECIFICATION forming par: of Letters Patent Naast-1.228, dated December 2e, 188e. Application filed Jnly17f1886. Seria-1 No. 208,316. (No model.)

To all whom, t may concern.-

Be it known that I, SAMUEL B.. SPENcE, a citizen of the United States, residing at Lemont, in the county of Cook and State of Illi- 5 nois, have invented certain new and useful Im,- provements in Dumping-Cars,which are fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 represents an elevation ofthe dumping side of a car containing-my improvements; Fig. 2, a similar elevation'of the opposite side of the car; Fig. 3, a cross-section of the same, taken on the line ma, Fig. l; Fig.

VA 4, a plan section of the same, taken on the line y y, Figi l; and Fig. 5, a side elevation and plan of one of the hingeirons detached.

My invention relates to that class of dumping-cars in which the body of the car is tilted 2o for the purpose of discharging the load.

The invention relates more particularly to the means for supporting the body of the car upon the truck, whereby it is elevated considerably above the latter, and may also be turned around upon a pivot, so as to be discharged in different directions.

It also relates to devices for supporting and securing the carin position and strengthening it in' parts where it requires special support.

I will proceed to describe in detail one way in .which I have carried out my invention in practical form, and will then point out delinitely inthe claims the particular Iimprovements which I believe-to be new and wish'to protect by Letters Patent.

In the drawings, A represents a car-truck of any ordinary construction, such asis gener- Qally used with dumping-cars. A further descriptiou is not here required. Aframe, B, for supporting the car, is mounted immediately uponthetruclI-frame. Inthisinstanceitis composed of two beams, b b', arranged at right angles to each other, the former arranged lengthwise and the latter transversely of the truck, and placed immediately over the interior beams or sills of the truck-frame, which run in the same direction. These beams are joined by halving at theirlintersection, and are suitably secured to the beams of the truck-frame below. A strong bolster, C, isffastened to this support by a pivot-pin, @,which passes down through the bolster, supporting-frame, and interior beams ofthe car-truck, as shown in the the bolster by suitable hinges, F, which are located at one edge of the bolster and connect the beam to it by its corresponding edge.

I make the hinge-irons in a peculiar Way. They have two straps, ff', the former extending horizontally over the topK of the bolster or 7o bottom of the beam and across the same, and then. bent over along the other side of either of these pieces. The other strap, f', extends perpendicularly from the eye along the side of the piece to which it is attached, so that the bolster or beam, as the case may be, is embraced on three sides by this hingeiron,which is secured in place by a bolt, f 2,' passing through the timbers and the opposite ends of the irons. These hinge-pieces, constructed and applied 8o vin thislway, serve to strengthen the two parts to which they are applied, to resist the strain which is broughtupon them, and at the same time make a very'strong and secure hinge. The respective pairs of irons constituting the joints are secured together by a rod, F', passing through the eyes of the hinge-irons.

Brace-rods e are attached to each end of the beam E, and extend upward on each side thereof to the respective sills of the car-body, thereby 9o forming a kind of truss-support for thelatter. These truss-rods may be in one piece, 0r they may be divided at each end of the beam, as may be desired. As the bolster and beam are arranged centrally Aol" the truck and car-body, it is evident from the description above of theV location and arrangement of the hinges that the latter are thrown out slightly to one side of the central line of the car, as will be readily seen in Figs. 3 and 4 of the drawings; but loo` the car-body rests on the broad supportingsurface provided bythe upper face of the bolster, which in turn rests upon a corresponding face of the supporting-frame below. The car-body, on the same sidel as the hinges, is provided with a hinged or swinging side, d, which is hinged or pivoted to standards d', rising from the corners of the ear, by means of posts d2, extending upward from this side of the ear. This hinged side of the car may therefore be swung outward and at the saine time away from the body by this arrangement and location of the hinges. Brace-rods d3 extend inward and downward from the upper ends of the posts d2, and are secured to the cross-sills of the car-body.

Alatch, G, is pivoted to the bottom of the car- -body and arranged to engage with the lower edge of the swinging side to hold it in place. This latch has a long tail-piece, g, projecting back from the pivot, and weighted so that its action will be to hold the latch up into position of engagement, as shown in Fig. 1 of the drawings, without any other appliance. Of course, when the car is tilted to dump the load, this latch must be released, and for this purpose I provide a rod, H, passing through from side to side of the body at the bottom thereof. This rod is provided at one end with an arm, h, bent like a crank, and arranged to lift the weighted end of the latch when it is turned upward by oscillating the rod. At the other end of the rod, on the opposite side of the car, is a handle, 7L', by which the rod is oscillated to release the latch. Instead of wei ghtin g the latch, a spring may be arranged to hold it in place; but the construction above describedwith one end weighted-is simpler and less liable to get out of order.

As the bolster to which the car-body is hinged is free to turn entirely aroundfit is evident that the car-body may be turned entirely around or half-way; hence it is necessary to provide for the discharge from one side only of the body, and so I make but one side of the latter hinged to swing outward. As the car-body may be turned, as stated above, it may be dumped on either side, or at`the rear, with a single swinging side door.

On the side of the car opposite to the discharge is a support, I, which is in the form of a bail, hinged at its ends to the bottom of the car-bod y, so as to depend therefrom, and curved upward at its central portion, as shownl in Fig. 2 of the drawings. The ends of this bail are also preferably bent over at about right angles, so as to form a fiat longitudinal portion resting against the sills of the car-body, and thereby taking the support instead of leaning entirely upon the hinge. This bail is arranged so that it is over the side sill of the truck-frame whend the ear-body is up in ordinary positionand'on each side sill are forked guides or keepers J, to receive the bail at itsM opposite ends. It will be seen that this provides an efficient support for the car-body on the side opposite to the discharge, and as this body may be turned entirely about, the keepers for the bail are arranged on each sill, so Y as to provide Yfor the proper support of the car whichever way it is turned. On the same side as the bail is an ordinary fastening-chain, K, and a turning-hook, 7c, in each of the side sills of the truck below. This is an ordinary device for securing the body in an upright position in dumping-cars, and has no new function here. It' desired, the hinged bail support may be applied to each side of the car; but in that case the bail on the discharge side would have to be swung before the car-body could be tilted.

It will be noticed that with the construction and arrangement of the devices heretofore de! car-body upon the truck set the body at a conv` siderable distance above the truck. This is one of the results aimed at by the employment of these devices, for by thus setting the carbody up Ireadily obtain the required tilt for the dump of. the load into the required position, and also for its ready discharge from the car.

It will be noticed that the car-body has but one hinged side for dumping the load. I.

have already explained that this is all that is necessary with the pivoted bolster, which permitsthe car-body to be turned Ainto any required position for dumping. It may be said, in addition, that with the peculiar hinginglof the car-body to its support described above it is not possible to tilt the car on both sides. As the hinges are at the meeting edges of timbers having broad flat surfaces in contact with each other, it is of course impossible to tilt the car in more that one direction.

I do not wish to be understood as limiting myself to all the details of construction which have been described above, for there may be modifications in construction without departing from the main features of my invention.

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

1. In a dumping-car, the main or ordinary truck-frame, in combination with a supplementary frame, B, mounted on vthe truckfralne, the bolster C, pivoted to the supplementary frame, and the car-body D, hinged to the bolster at one of its side edges, substantially as and for the purposes set forth.

2. The bolster, in combination with the hinges F, provided with straps extendingv around the bolster and bolted thereto, and the ear-body secured to the bolster by said hinges, substantially as and for the purposes set forth.

3. The car-body D, in combination with the IOO IIC

body, substantially as and `for the purposesl set forth.

6. The car-truek provided with keepers J, in combination with the tilting body, and the bail support bent at its ends, as described, and hinged to the bottom of the car-body, substa11` tially as and for the purposes set forth.
