DUM P-CAR.

SPECIFICATION forming part of Letters Patent N 0. 744,201, dated November 17, 1903.

Application filed February 20, 1903. Serial No. 144.915. (N model.) I

To allwhom it may concern: N

Be it known that we, FRANK S. INGOLDSBY and JOSEPH R. BOWLING, both citizens of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Dump-Cars, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawings.

[O The object of this invention is to produce a very light and strong dump-oar which at the same time shall be very simple and cheap in construction.

The car which constitutes thisinvention is [5 of what is known as the Ingoldsby type that is, it has a central longitudinal beam to which there are hinged dumping-doors adapted to swing downward at their outer edges.

The car herein shown is particularly adaptable for the transportation of ore, though of course is not limited thereto.

The particular features of the present invention are the construction and arrangement of the central longitudinal beam, the stops for limiting the downward movement of the dumpingdoors, the construction of those doors, particularly at their outer edges, and the cooperating arrangement at the lower edges of the car side, and finally the ar- 0 rangement of the operating member for the locking-levers. All these features will be hereinafter more fully explained, and the essential combinations embodying the same set out in the claims. I

The drawings clearly disclose this invention embodied in an ore-car.

Figure 1 is a plan, half top plan and half bottom plan. Fig. 2 is an elevation, half-outside and half sectional. Fig. 3 is an end 0 view, half-outside and half-sectional. Figs. 4 and 5 are vertical sections on the lines 4 4 and 5 5, respectively, of Fig. 2. Figs. 6 and 7 are details in horizontal section, being respectively on the lines 6 6 of Fig. 3 and 7 7 of Fig. 5. Figs. 8 and 9 are details of two forms of connecting-plates used.

The car, as shown, is made almost entirely of sheet metal and rolled forms. It has plate girder sides A A, composed of vertical metal plates which, have riveted along their upper and lower edges and intermediatelythe angle members 01,, a and a respectively. The projection of the horizontal flanges of these members increases with the tendency of the side of the car to bow outwardly. Thus the uppermost flange a is the widest, the intermediate flange a the next narrower, and the bottom flange a the narrowest.

Between the sides near the ends of the car are the inclined end floors B. These inclined 6o ends are flanged downwardly at their edges 1) and are there riveted to the plates A. The inclined ends are strengthened and braced by the angle-strips b, 19 and 19 which extend across them on-their under sides at their upper edge, their lower edge, and intermediately, respectively.

The central longitudinal member of the car is designated C. As here shown, it carries substantially half the load. It includes a ridge-plate inclining downwardly on opposite sides and extending from bolster to bolster, passing through the end floors B, which are connected toit through the downward flanges of the connecting-strips b.

The ridge-plate of the central beam C is braced laterally at various'points by composite stiffening members D beneath the beam. This composite stiffening member, as shown, is composed of the angle-strip d, bentaccord- 8o ing to the angle of the ridge-plate and riveted to it, the two connecting-straps d d, riveted to the strip d and the ridge-plate, the tie angle-strip d riveted near its ends to the connecting-straps d d, and the connecting-plates d riveted to the flanges of the angle-strips d and (1 This make a light and at the same time strong triangular brace beneath the ridge-plate. To further stiffen the central beam, (but not necessarily essential to it, though of utility in taking the shocks and strains due to buffingand tugging of the cars,)

we provide a pair of outwardly-facing channels E E, which run through the car and have riveted to their webs inwardly-turned flanges 5 d on the inner edges of the plates CF. The longitudinalv channels E are secured at their ends by angle-plates e to the end sills F of the car. They extend over the bolsters G of the car, which, as shown, consist of a pair of too outwardly-facing channel-beams extending across the car beneath the central beam and carrying the usual center bearing 9 and side bearings g. The ridge-plate C is connected with the bolster by the angle connectingpieces 0, riveted to each of them.

The draw-head H occupies a sheet-metal frame H, which abuts the outer side of the bolster and is secured to it. This frame is also secured to the channel-beams E and is supported from the end sill F by the depending brace K. The end sill is riveted and secured by the connecting-platesf to the extension-beams a connected to the car sides. On the inner sides of the bolsters are the plates L, connected to the bolsters and to the longitudinal channels E E. The bolster is thus bound to these channel-beams through the draft-plates H and these backing-plates L. At its outer ends the bolster is connected with the lower chord a of the car side by connecting-plates 9 The dumping-doors P consistot' sheet-metal plates secured to floor-beams beneath them. These floor-beams extend inward between the straps d of the triangular brace D, to which they are hinged by pins 19, projecting each way from the floor-beam. The floor-plates are turned upward at their inner edges 19 to make a tight joint with the lower edge of the ridge-plate C. At their outer edges 19 the floor-plates extend beneath the lower edge of the side plate A and the lower chord a a suflicient distance to make a tight joint therewith. These doors are braced at their outer edges by the longitudinal angle-strip beneath the floor-beams and secured to the door by rivets passing throughthese floor-beams and other rivets through distance-blocks 19 located intermediately of the floor-beams. This eifeotively braces the outer edge of the dumpingdoor. \Vhen the car is in condition for loading, the doors P are held horizontally by the engagement with the outer ends of the floorbeams 12 of hooked levers Q, pivoted to the sides of the car. The outer ends of the floorbeams are also hooked. These two sets of hookshave cooperatinginclined bevels todraw theparts snuglyinto place. The pivoted hooks Q are adapted to be concurrently operated by a hell-crank lever S, connected with the hooks by a link T. The lever S is normally retained in an elevated position by a lockingbar V, which lies beneath it, and is pivoted by a pin 1' to the guide-iron U. This bar V may be locked by the pin V. When this pin is removed, the locking-bar V will be turned aside and the leverS swung downward. This swings the hooks Q on their pivots to release the floor-beams p and allow the doors to drop. To form a stop for the doors as they drop, preventing their passing inward far enough todischarge on the rail, we provide at certain points beneath the central beam stops consisting of downward outwardly-inclined projections, as d and (1 These projections are respectively extensions d of the angleeted to the extensions d and (1 ties d and additional members d Near the center of the car the adjacent extensions d are connected by the cross-plate d At the points where these extensions are we also extend downward the connecting-plate d beneath the triangular brace proper, as indicated at d, this extension-plate d being riv- Thus when the door drops the plate P is beyond the edge of the extension-plate d*; but the floor-beams p, which are out of alinetnent with these extension-plates, impinge at the door ends the stops d and at the center the cross-plate (1 This makes an elfective bumper for the door, holding it in position where the load will be discharged clear of the rail, while at the same time the car may be shifted on the rail with the doors down, ifdesi red. An inspection of Fig. 3 will show this and will also show that though the door inclines outwardly in its lowest position the discharge-space is not contracted thereby, being greater than the horizontal distance between the lower edge of the central beam and the side of the car. In order to allow the dumping-doors to be conveniently elevated,we provide at their outer edges loops orhandholds p, which may be taken hold of by the attendant and the door thereby raised.

lhelockin, ;-levers Q are mounted on blocks a secured to the car sides. These levers extend through slots at in the lower chords (1. of the sides, as shown particularly in Fig. 6. This arrangement, as well as the projecting flange at above the levers, effectively protects them from injury. The slots through the lower chord a are located in or very close to the neutral axis of the horizontal flange of that chord-that is, the line where the stress in it changes from tension to compressionso that, practically speaking, they do not weaken the chord.

In operation after the car is loaded it is dumped by simply removing the pin V, turning aside the locking-bar V, and shoving downward the lever S. This swings the hooks Q to release the doors, and the latter drop by gravity, discharging the load. Thereafter the doors are raised by the attendant, who takes hold of the handholds p and raises the doors to a horizontal position and then by taking hold of the link T shifts the hooks Q sufficiently to hold the door, after which he moves the lever S home and-locks it with the locking-bar. The lever S is so proportioned that when it has been shoved downward to release the doors the short arm S thereof stands in a substantially vertical position, so that when the attendant pulls on the link T he has this arm S in position of greatest leverage, making the operation easy and convenient. The lever S may be operated from the side of the car or, if desired, from the platform m, which extends across the end of the car. This platform is also of use for operating the brake, which is indicated in the drawings by the hand-wheel and rod N, connecting-chain N, and equalizing-lever N We claim- 1.
