.TU LLZZ whom/ t may concern: Beit known that I, EDGAR PECKHAM, a.

citizen of the United States, anda resident of New York, in the county and State of `,New

York, have` invented. certain new. and useful n AThis I ac'complish by` the uemployment of `,t1iissbracings supported by the truck-frame,

as hereinafter explained.v Q

My invention is illustrated in the `accompanying drawings, Whereinl Figurel isa side elevation of `one end of a car-truck, showing my invention applied thereto. Fig. 2is a detail elevation showing` a somewhat different embodiment of the in` vention. Figf isfafdetailviewof the extreme end of the truck-frame,` showing, the verticallymovable bolt and the roller with which it coperates; and Fig. 4 is an end View.,` of Fig. 3, the verticallyfmovable boltbeing omitted. j g Y In the drawings like parts` are indicated by like numerals vinthe several views. It is to be understood that each corner of theV carfbody is to be provided with `the diagonal truss-bracing shown, the latter being sup-` ported by the truck-frame.`

Referring to the drawings, 5 indicates the upper longitudinalA beam of the truck, which is preferably duplex, and 6 the bracing-beam between the yokes. These beams are riveted to the yokes, as indicated. To the fouter sides of the yoke, which is indicated by 7, there is` riveted longitudinal beam 8, which affords support `for springs, as shown, beam 8 being of greater or less length, according to the pro- `portions desired of the spring-base eXten e. serial No. 581,391. (No model.)

In the drawings,11 indicates the car-wheels, 12 theazle-boxes, and 13 removable repairing-piece between the lower legs of the yoke. Adjacent to the,A yoke there is mounted `on extended end beam S an elliptic spring 14, which is connected to the sill 10, as shown, and in advance of the` elliptic spring there is arranged `a spiral spring 15, supported on said `beam 8, with its rod or spindle connected to the sill and extending below the beam and `provided with a tension-spring and nut, as shown. rl`he features thus described are shown inLetters` Patent heretofore granted lto me` orin applications pending, and are not claimed in the present application, being described herein `merely for the sake of the completeness of this specication.

` fAt or near the vend of longitudinal beam 8, `which isduplexjby preference, there is rivetedthe casting` 16, with a collar 17, which ,and with the depending bracket, as 18, below the under edge of said beam. In this bracket there is j ournaled a roller I9, this being one "convenient mode of supporting the roller. Bolt `or support 42Ois secured at its upper end to `the car-sill 10, and moves with the carbody and is independent of the truck-frame. Surrounding bolt 2Q is a spiral spring 21, which ispreferably made duplex, as shown in Fig. 2, and which is seated in a socket on beam 8 and has a bearing at its upper end on `a collar beneath a bracket on `the sill 10. Bolt 2O extends beneath beam S in operative contact with roller 19.

To the lower end of support or bolt 2O there is suitably connected the brace 22, which, from its point of connection to the rod or support 20, extends outwardly and upwardly and is adapted to be connected at its outer end to the car-body. As shown, the diagonal brace 22 is provided at its outer end with a hori- Zontal portion 23 to facilitate its attachment to the oar-body, and, as also shown, it is provided with a turnbuckle device 24, whereby its tension may be adjusted. The diagonal brace 22 may be formed integral with the supporting-bolt 20, as shown in Fig. 2, (and I prefer to so make it,) and it need not in every case be provided with a tension-adjusting device. The object of` this diagonal-bracing lrests `upon the upper edge of the said beam,`

means at the ends of the car is to prevent the IOO teetering, oscillation, or sagging of the ends of the car-body, and is particularly intended for car-bodies of unusual lengths. The roller 19, interposed between the upright bolt 20 and the truck-frame, serves to relieve said bolt of friction and also affords a bearing for the same at its lower end, the rotation ot' the roller in the up-and-down movement of the car-body also insuring an easy play of said support in its bracket.

By the described construction the requisite flexible support is afforded at the extreme ends of the car-body, an important consideration when car-bodies of unusual length are made use of.

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

1. In a car-truck, the combination with a horiZontally-extended end beam and an upper longitudinal chord or sill, of a supportingtruss connected to said upper chord or sill and passing below said extended end beam at its outer end and rigidly connected to a diagonal member which extends outwardly and upwardly and beyond the truck-frame, substantially as set forth.

2. A car-truck frame having horizontallyextended end beams and spring-supported sills or upper longitudinal chords on which to mount a car-body, and provided at its ends with supporting-trusses connected to said sill or upper longitudinal chord of the truckframe near its outer ends and extending beneath said end beams and having bearings thereon and rigidly connected to diagonal members which extend upwardly and outwardly beyond the truck-frame, substantially as set forth.

3. In a car-truck, the combination with the sill or upper longitudinal member of the truckframe provided with a bracket, and a horizontally-extended end beam, as 8, of spiral spring 21 between said sill and beam 8, and its spindle connected to said bracket and extending beneath beam 8, said bracket, spring and spindle being at the outer end of the extended end beam, and a supporting-truss rigidly connected to the lower end of said spindle, inclined upwardly beneath the car-body and provided with turnbuckle, as 24, substantially as set forth.

4L. In a truss or bracing for cars, the combination with the truck-frame, of vertical and diagonal bracing members rigidly joined together at their lower ends, the former secured to the car-sill or the top frame of the truck and the outer end of the latter adapted to be connected to the outer end of the car-body, and a roller interposed between the truckframe and said vertical member to relieve the latter of friction and arranged to afford a bearing for the truss-bracin g at the juncture of said vertical and diagonal members, substantially as set forth.

5. The combination with a car-truck having a beam or extension at the front of the yoke, of a diagonal truss-bracing with its outer endextending beyond the truck-frame and adapted to be connected to the outer end of a car-body, and an upright bolt or support connected to the top frame of the truck or the car-sill with its lower'end rigidly secured to the inner end of said diagonal truss-bracing below said beam or extension at the front of the yoke, and a roller located beneath said beam or extension between the truck-frame and said upright bolt to afford a bearing for said truss-brace at its juncture with the upright bolt, substantially as set forth.

G. In a car-truck, the combination with the extended end beam 8 and a casting as 18, provided with a roller, as 19, of a supportingtruss connected to the sill or upper longitudinal member of the truck-frame and operating through said casting in contact with said. roller and extending outward and upward beneath the car-body, substantially as set forth.

7. In a car-truck, the combination with an extended end beam provided at its outer end with a casting carrying a roller, of a supporting-truss connected to the sill or upper longitudinal member of the truck-frame, extend ing through said casting in contact with said roller and outward and upward beneath the car-body and provided with means for adjusting its length, substantially as set forth.

8. In a car-truck, the combination wit-h an extended end beam 8 provided at its end with a casting carrying a roller, bolt or supporting-spindle connected to the upper longitu dinal member of the truck-frame and passing through said casting in contact with said roller, and apspiral spring surrounding said bolt above the casting, of a supporting-truss extending from the lower end of said bolt upward and outward beyond the truck-frame, substantially as set forth.

9. rIlhe combination with the duplex extended end beam S, of casting 1G bolted between the members of said beam and provided with a collar at its top which rests on the upper edges of said beam 8 and also provided with a depending bracket projecting below the lower edges of said beam and having a roller as 19, and a supporting-truss operating through said casting and projecting upward beneath the car-body, substantially as set forth.

10. The casting 16 herein described provided with a collar 17 at its top and with 'a depending bracket 18 at its bottom carrying a roller, as 19, substantially as' set forth.

11. In a car-truck, the combination with the yoke, the horizontally-extended end beam 8 and the under truss-beam 9, of a roller secured to the outer end of said end beam and a truss comprising a Vertical member attached at one end to the upper chord of the truckframe and coacting with said roller and a diagonal member secured to the lower end of the vertical member and extending upwardly and outwardly beyond the truck-frame, substantially as set forth.
