FREIGHT-CAR TRUCK.

SPECIFICATION forming part of Letters Patent No. 553,103, dated January 14, 1896.

Application filed October 26, 1895. Serial No. 586,958. (No model.)

To all whom, it may concern;

Be it known that I EDWARD CLIFF, of New ark, in the county of Essex, in the State of New Jersey, have invented new and useful Iniprovements in Freight-Car Trucks, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

. My invention relates to car-trucks, particularly freight-car trucks; and the object is to provide a simple and durable truck that will allow the wheels and axles, with the axleboxes, to be readily and easily removed, and that will also allow the several sides of the pedestals to be formed of wrought-iron or steel, while the balance or central portion of the side frames are made of cast metal.

To this end my invention consists in the combination, with the wheels and axles and the axle-boxes, of side frames extending between the axle-boxes, a removable part or yoke lying on several of the sides of each axle-box and secured to the end of the side frame, and a bolster extending between and secured to the centers of the side frames; and my invention consists in certain other combinations of parts, hereinafter described, and specifically set forth in the claims.

In the drawings hereto annexed and forming a part of this specification, Figure 1 is a side elevation of my improved freightcar truck. Figs. 9 and 3 show a modified form of fastening device for securing the removable part to the end of the side frame. Figs. i and 5 are side and top plan views, respectively, of a modified form of the removable part, together with its fastening devices. Fig. 6 is a top plan view of the truck-frame shown in Fig. 1; and Fig. 7 is a side elevation of the bolster, partly in section and taken on line a: of Fig. 6.

Referring specifically to the drawings, A A are the axles and wheels, and A is an axlebox. In Fig. 1 one of the axles and wheels is shown in broken lines, and its box is removed to show more clearly the construction of the pedestal.

B B are the side frames, which are preferably made partly of cast metal and partly of wrought metal, and O is the bolster extending between and connecting the centers of the side frames together, as hereinafter described. The side frames are substantially I-shaped in cross-section, but are preferably perforated as shown. The upper and lower flanges b b are broader in the center of the beam than at its ends, as shown in Fig. 6, and are there provided with ribs or gibs b I) on both the upper and lower sides to retain the bars forming the bolster C The ends of the side beams are made deeper than the central portion to form the inner sides of the pedestals. The ends of the beam in Figs. 1 and 2 form the inner side guides for the axle-boxes A. The other three sides of each pedestal are formed by a rectangular removable part or yoke D of metal, which is secured to the side beam in any suitable manner. In Figs. 1 and 6 these parts are secured in place by gibs c and long bolts (3, which extend through the ends of the yokes lying upon the upper and lower sides of the beam and through the beam 13.

The lower end of the yoke D is simply perforated, but the upper end is recessed or slotted and provided with a gib d to bear upon one side of the head of the bolt 0. This construction allows the removal of the yoke for the purpose of removing the axle-box without entirely removing the bolt 0. In order to remove the yoke it is only necessary to remove the nut from the lower end of the bolt 0 and raise the bolt until its lower end is above the lower end of the yoke,'when the latter may be removed by drawing the yoke outward from the end of the side frame or beam B. 7 v

The inner long side of the yoke D forms the outer guide for the axle-box. Bearing against the upper portion of the yoke is a springsocket e for the upper end of 'the spring 6 bearing on the top side of the axlebox. A bolt 6" passes vertically through the spring and the upper horizontal portion of the yoke. The modification shown in Figs. 2 and 3 consists simply in providing the upper and lower flanges at the ends of the side beam with perforated ears h to receive clips h, which secure the yoke D to the beams. In this case the ends of the yoke are not perforated, as the clips are U-shaped, but the yokes are provided with gibs i to lie on each side of the clips h, as shown in the drawings.

- In Figs. at and 5 all the sides'of the pedestal are formed by the removable yoke D. This pedestal, however, is formed of two movable parts which are secured together and to the end of the side beam B by short horizontal bolts parallel with each other. The sides of the pedestal are integral with the horizontal upper side, while the lower side, D, is removable. By removing the bolt a the pod estal will swing outward from the end of the side beam on the bolt to. Then, by removing one or both of the bolts 6/ and a, the axlebox with the axle (not shown in this figure) may be removed from and through the bottom of the pedestal. This construction is, in some respects, superior to the other, as it allows the removal of the box without entirely removing the yoke from the side beam.

The bolster or cross-beam C of the truck is formed. of three bars, the ends of two being connected to the side beams above the same, and the other being connected to the beams below the same. The upper bar is slightly arched or raised in its center above its end portions, the lower bar extending between the lower sides of the beams is straight and horizontal, while the third or central bar is bent to lie with its center in contact with the lower bar and with its ends in contact with the ends of the upper or arch bar.

In the center of the bolster, between the bars, is a separator formed of an angular bar f, having its center in contact with the lower side of the arch-bar below the centerplate G, and secured thereto by rivets. The end portions of the bar f extend downward and outward toward the sides of the truck and are provided with horizontal feet which abut against the angle formed in the central bar and are secured thereto, and also to the lower straight bar, by rivets g g. All of the bars are perforated in their center to receive the king-bolt. (Not shown.)

It will be observed that the bolster may be formed in this way without castings and with strips of wrought iron or steel.

Side bearings H of any suitable and wellknown form may be secured above the ends of the bolster, as indicated in the drawings.

Each end of the bolster O is secured rigidly to the side frame by eight short bolts passing through the bars of the bolster and the flanges of the side frame. Four bolts pass through each flange, as shown.

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

1. In a freight car truck, the combination with the wheels and axles, and the axle-boxes, of side beams extending between the inner sides of the axle-boxes, a removable yoke lying on several of the sides of each axle-box and secured to the end of the side beam, means to secure the said yoke to the side beam, and a bolster extending between and rigidly secured to the centers of the side beams, as set forth.
