To all whomawzg ooh-corn." Be it known that l, l l lLLlelii E. luowLER,

Ilia, residing at Mount Lebanon, in the county of Allegheny end; State of Pennsylo voriie, s. citizen of the United States, have invented or discovered certain new and use- ;tul leiprovements in Securing BralwBeam pports to Trocks, of which omprovements the following; is o specification.

The invention described herein relates to the, class or type of devices known inthe art es brake beam supports, which are usedos auxiliaries to the hangers to maintain the brake shoe Whether in contest with the trcatl of the Wheel or in normal position in proper concentric position relative to the wheel and to ensure the pr er application otthe brake shoes regardless hin limits of the i1an1cter ot the \vhccls. hose supports consist of one i two spring b Whether'thc broke beam is to be supported oi two points in azlclitionto the usipil hangers, and a shoe or shoes IDtCIPOSG(l between the brake beam and the rail or rolls. Prefcrobl v and in most cases the rail or rails are secured to the spring plank of the truck oncl on account of the position of the spring plank relative to othc parts of the. truck Eliliicultv is encountered in so attacliiu r the rails which extend on both sides oi the spring plank in such moi-loci? as will perm t of the easy removal and replsccmeut of the mils when repairs are necessary.

The invention described herein relates to certain ii'nprovemcnts in the rhczor er of ettoching the rails described and claimed iii :in application filed February 28, 192%, by Broderick Haskell, Serial No. 695,795, which consists, generally stated, in forming the rail. with a portion adapted to he passecl ougli on opening in the spring plank and idiiig means whereby the portion proi through the opening is prevented n occidental withclmwal. The improvehereinafter more fully described ilull. claimed.

lo the accompanying drawings forming; a port of this specification, Fig. 1 is a plan zieir showing a portion of the spring-plank of e truck and a supporting mil secured to the plank in the ma'nner claimed. herein; li i s: 2 and 3 are sectional views 01. "lanes i-eoicotecl respectively by the lines 3..lI----II s or roils,'(lep ci1clent uponv serial No. motel.

end fil -ill, Fig. ii; Figs. eleml 5 are views similar to ldigs. 1. and. 2 illustrating omodification of the improvement; Fig. 6 is 1). view similar to Fig. 5 illustrating a znodificition of the improvement; and lg. 7 is a sectional View on a. plane imlicetecl by the line Vll-Vlll.

lo the practice oi the invention the supporting rail extends across the spring plank lend projects a. sufiicierit distance on each side of the spring plank to underlie the terision members 2 of the brake beam. The end portions 3 of the rail are so bent as to'heve an upward inclination when the rail is secured to the truck and. on these portions 3 are moi' sbly mounted blocks or shoes 4; heyiiog seats 5 for the tension members 2. The shoes-ore held as against occidental. move oieiit ofi of the rails by shoulders L which are conveniently formed by heeded rivets,

shown The intermeclietc portion of the rail is so bent that the rail will beer on the pleiik only at points adjacent to the edges of the plank as 'inclicetccl id, such bearing portioos having sufficient length to reirieio. in contact with the pistol: during permissibleioiigitudiriel movements of the rail. *The means employed for connecting the rail to the plank ct point intermediate the hem ings G are so constructed that the portions intermediate the seats must be deflected from normal before such connection can be cliectecl. lo the construction shown herein the means employed to attach the rail to the plank consists of 9. loop or Ushapecl portion .'Z oppositely inclined resilient portions 8 ex tending from the loop to the bearings (3, said loop being passed through. on opening in the spring plank and held in position by a' lacy or pro.

y reference to Fig. 2 it Will be seen that the portions 8 Will when the bearings 6 contact with the plank, be inclined away from the plank and the loop is made of such a height that the portions 8 must be .cleflectccl 15 locking" pin 10 on the opposite side.

shoulders 11 adapted to bear against opposite edges of the opening 9 to prevent its longitudinal movement out of the loop. The opening through the spring plank is made of v 5 such a width relative to the length of the opening in the plank and prevent such 1on gitudinal movement of the rail as will move 10 the bearings 6 out of contact with the plank.

It is characteristic of the described construction that the rail has three points of bearing on the spring plank, i. e., the bearings 6 on one side of the plank and the rail or at least the portions of the rail intermediate the bearings 6 are resilient.

As is well known in the art, the spring plank may be formed by channel bars 1 as shown in Figs. 1, 2 and 3, or by spaced angle bars 1, as shown in Figs. 4 and 5.

When the plank is formed of angle bars the supporting rail is attached to a plate 12 extending across the gap between the angle bars and riveted or otherwise secured thereto.

When applying the support rail above the 'spring plank, which can be readily done when the plank is formed with narrow or low flanges, the portions of rail intermediate the inclined portions carrying the shoes and the loop 7 are made straight as shown in Figs. 7 and 6, the low fianges 13 of the plank 1 operating to perform the function of the bearings 6 in the construction shown in Figs..1 to 3, of so supporting the middle portion of therail in which the loop is located in such position that port-ions mu'fst be deflected in order to permit of the rail being locked to the plank. By reference to Figs. 1 and 2 it will be seen that by the employment of a shoe hav; ing an open-topped seat or saddle, the brake beam can be placed or replaced in position without changing the position of the sup porting rail which carries the shoe, and also that the supporting rail and shoe can be placed in position without changing the connection of the brake beam with the truck and without changing either the shape of the shoe or its manner of connection with the supporting rail.

It is characteristic of'the construction shown and described herein that as the shoes are freely movable along the supporting'rziils and that the tension member can slide freely along the seatsor saddles of the shoes the brake beam is free to move at all times in directions at an angle to and parallel with the supporting rails and thus automatically adjust itself to operative position.

I claim herein as my invention: 1. The combination of a truck element and a supporting rail having spaced bearings on one side of the truck element, and a The bearing on the opposite side of the truck element, the latter bearing being intermcdt ate of and spaced from the other hearings.
