CAR-TRUCK.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed July 11, 1905. Serial No. 269,144.

To all whom, it may concern.-

Be it known that I, WILLIAM F. KIESEL, J r., a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Car-'lrucks, of which the following is a specification.

This invention relates more particularly to improvements in four-wheel trucks for railway-cars; and the objects of my improvements are, first, to provide a truck which will be adapted for use in connection with cars having deep center sills, where it is required to drop the center-plate to near the level of the axles; second, to provide for greater flexibility of the springrigging by passing the bolster across the truck under the wheel-pieces and supporting it therefrom by stirrups without the use of a spring-plank, utilizing the wheelpieces as equalizers and arranging spring resistances for the bolster against both vertical and lateral motion; third, to provide abrakerigging especially adapted for the truck, which, however, is made the subject of a separate application, and, finally, to provide an all-metal construction so arranged and built up as to accomplish a decrease in the weight of the truck, while maintaining full strength in all parts by the judicious location of hangers and distribution of metal. 1 accomplish these objects by arranging and constructing the several parts of the truck in the manner illustrated in the accompanying drawings, in which Figure 1 represents a plan view of my improved four-wheel car-truck with the top portion of one of the wheel-pieces broken away to show the parts contained between the members thereof; Fig. 2, a side elevation of the same with parts broken away for one-half the length of the truck to show the arrangement of the parts between the members of the wheel-pieces; Fig. 3, a central longitudinal vertical section of the truck; Fig. 4, an end elevation thereof with parts broken away to show details of construction; Fig. 5, a transverse section on the line 00 min Fig. 1; Fig. 6, a vertical section through one of the wheelpieces and bolster-hangers on the line y y in Fig. 2, drawn to a larger scale; and Figs. 7 and 8 details showing a hanger-gib and its support.

Like numerals designate like parts in the several views.

The center-plate 1 rests upon a bolster 2, formed from a steel plate pressed into the shape of an inverted U, the crown of the bolster being flat and of considerable breadth and the length of the bolster being such as to carry its ends out beyond the wheel-pieces 3 at each side. These wheel-pieces consist of pairs of steel channels, the members of which are set apart with their flanged sides turned toward one another. The bolster at each end rests upon anest of six elliptic springs 4. Said springs rest in turn upon carriers 5, which are supported at each end by hangers 6, depending from supports between the members of the wheel-pieces. The bolster is, in effect, a spring-beam hung in stirrups at each side ofthe truck. In order to properly support these stirrups, which must carry the weight of one-half the car, I rivet between the members of each wheel-piece a pair of horizontal channels 7, the flanges of which are faced in opposite directions and riveted to the wheel-pieces just inside of their flanges. Upon the upper channels 7 are riveted the supporting-plates 8, upon which rest the gibs 9, from which the hangers 6 swing. These gibs are flat plates passing through an eye at the top of the hangers, and they are provided on their top edges with a semicircular groove into which the convexed end of the hanger-eye is fitted. This permits the hangers to rock sidewise on their supports, the gibs being held against movement on their supporting-plates 8 by having their bottom edges set into the ribbed sockets 10, formed on the top of said plates. The lower ends of the hangers are coupled to the ends of the carriers by means of similar gibs 9, passed through eyes in the carriers and hangers in inverted position. (See Fig. 6.) By this arrangement the bolster 2 is allowed some lateral play with respect to the wheelpieces, and the necessary flexibility in th truck is attained.

Between the hrizontal channels 7. below the gib-supports, are spacer plates or castings 11 in order that the downward pull of the hangers upon the upper channels may be transmitted to the under channels, combining the two together in support of the weight upon said hangers. Below these spacers 11 and held in place by the same rivets which hold the spacers and gib-supports in place are steel castings 12, which hang down below the wheelpieces and are provided with vertical faceupon spring-coils 15, which rest upon the axleboxes, caps 16 being riveted between the members of the wheel pieces to receive these equalizersprings and the axle-boxes being guided in the pedestals 17. The upturned flanges of the pedestals at each side engage the outer faces of the members of the wheelpieces between them, said members being thereby bound together and strongly braced at these points. The pedestals at the bottom are connected by pairs of tie-bars 18, running from one pedestal to the other on each side, with space left between the members of each pair of ties sufficient to permit a jack to be applied directly under the axle-boxes so that the boxes may be raised withoutdisturbing the pedestal-ties for the removal of axle-bearings. There is also room between these pedestal-ties for the carriers 5, which support the elliptic springs, and under said carriers the ties are provided with safety-guards l9, intended to support the carriers in the event of the giving away of any of the carrier-supports.

The ends of the wheel-pieces are connected by depressed cross braces 20, which are formed from pressed-steel plates of inverted- U-shaped cross-section bent up at each end and provided with flat portions 21, which are riveted to the under flanges of both members of the wheel-pieces. Brackets 22, of caststeel, are riveted in the angles between the cross-pieces and the inside members of the wheel-pieces. The ends of the wheel-pieces are inclosed by cover-plates 23, which are flanged around the edges to fit around the sides of the wheel-pieces and are held in place by countersunk bolts which pass through an gle-pieces 24, riveted inside the wheelpieces. By this construction the wheel-pieces are held in rigid parallel alinement, and the members thereof are strongly braced against twisting or buckling.

The bolster is reinforced along its side edges by angle-bars riveted thereto on each side, and the sides are inclined upward at each end to meet the end cover-plates29, which are formed as a part of the side-bearing castings 28. This gives to the bolster the character of a plate-truss of great strength and comparative lightness in weight. Beneath the centerplate the bolster is strengthened and stiffened by cross-plates 25, formed from pressed-steel plates with flanges at top, bottom, and sides, the top and side flanges being riveted to the top and sides of the holster, said plates being reinforced by the angle-bars 26, riveted thereto and to the bolster on the side opposite from the plate-flanges. Between these braceplates 25 and beneath the hole for the kingbolt is a horizontal brace 27, intended to support the end of said bolt.

To allow for the side motion of the bolster relatively to the wheel-pieces and to return the bolster to mid1')osition after the deflecting force is removed, the bolster is equipped with abutments or follower-stops 30 and 33 at each side of the wheel-pieces, and helical'springs are positioned between followers 31 and 3 T, which engage the faces of said stops. The outside follower-stops 30 are formed by inward projections on the side-bearing castings 28, the inside follower-stops being steel castings riveted to the top of the bolster. The followers 31 are guided in chambered castings 32, riveted to the outside of the outer members of the wheel pieces, the springs passing through said outer members of the wheel-pieces into engagement with said followers. The followers 34 are squared and pass through corresponding holes in the inside mcmbers of the wheel-pieces and through guides formed on the brake-hanger bearings 36, which are riveted on the inward sides of the wheel-pieces. The horizontal channelplates 7 are bent apart, so as to pass over and under these sidc-motion springs and act to stiffen the wheel-pieces where they are cut away to permit the passage therethrough of the springs and followers. The side-bearing castings 28 have their upper surfaces adapted to receive bearing-plates attached to the under side of the car-frame. To reinforce and stiffen the bolster at the points where the inside follower-stops and side bearings are secured thereto, I provide the flanged braceplates 37, 38, and 39, the first two of which have end flanges riveted to the vertical sides of the bolster, and the rivets by which the side-bearing and follower-stop castings are secured to the bolster pass through thehorizontal flanges at the top of said brace-plates. 1 also provide with this truck a novel arrangement of brake-- rigging consisting of independent duplexbrake systems'for each side of the truck. Each of these independent brake systems comprises a pair of brake-heads set between the wheels and supported by inverted-U- shaped shackles 41. which are hung in sockets formed by upwardly-inclined lips at T0 at each end of the castings 36, which constitute these hanger-bearings. The shackles are held in place in their bearings by means of blocks inserted between the lips 40 and held in place by bolts, as shown in Fig. 5. Coupled to each brake-head is a vertical lever e3, said levers being coupled together by a connecting-bar 44:. The upper end of one of these brake-levers is coupled by connecting-rod 4:6 with a stationary eyepiece 45, formed on the hanger-bearing 36, and the free end of the other lever is coupled by a connecting-rod 47 to a horizontal equalizer-bar l8, which passes transversely across the truck over the centerplate, and consequently over or through the depressed center sills of a car, where they rest upon the center-plate. This equalizer-bar is coupled at the center to the brake system, and from an inspection of Fig. 3 it will be seen that a pull to the left on the equalizer-bar will act, through the brake-levers 43 and connections 44, to throw the brake-heads at each side of the truck to the right and left, and thereby set the brakes upon each of the four wheels, the brake system on one side of the truck acting independently from that upon the other side.

Variations in the forms of the several parts which go to makeup the truck and in the manner of assembling and building them up may be made without departing from the spirit of my invention. Eyebars may be substituted for channels, and the pressed-steel members may have substituted therefor members of like form constructed of built-up parts, and I do not, therefore, confine myself to the specitic details of construction herein shown and described.
