FLANGE'L To allw'lmm et 1n a/ l/ concern Beit known that l, Pour BYNUM, subject of the King of England, residing at Stratheona, Alberta, Canada, have invented cfa-'tain new and useful I mpro'vei'nents in Flanges, of' which the following is a sp a-.ificati on The present invention appertains` to wheels designed to runupon tracks, thepu rpose being to suplpl)r the same. with a yiel l.

that upon which the wheel is adapted to run'A to yield and prevent the lifting of the wheel when passing a f rog or crossing rail.

For a full un(lerstalnliingr of the invention and the merits thereof and also to acquire a knowledge ofthe. details of construction and the. means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side view ofa car wheel sup'- plied with a yieldable flange and adjunctive 'parts embodying the. invention. Fig.'2 is a sectional perspective View of the car wheel, parts being broken away to show more clearly the structural arrangement and details." Fig! 3 is a transverse section of the outer part of the Wheel and cooperating parts on a larger scale.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the. same reference characters.v

'lhe wheel 1 may be of any construction such asadapted to run upon a track and is provided upon its tread portion with the usual integral flange 2. A yieldable `Harige 3 is provided upon the opposite side of the wheel, the two flanges 2 and 3 adapted to embrace opposite sides of the tread ortion of the rail so to prevent lateral dlsplacement ofthe wheel and insure its retention upon thel track. The flange 3 is yieldable so as to pass over a rail, frog, or like part touchg tlunrz il` or track upon which the. wheel 1 Specification of?.

outer edge portion of a plate 4 placedv against the side of the. wheel 1 opposite to tli`at-pr0- vvided with the. flange 2.- The plate 4 is of annular formation v and itsouter ed e portionff` f constituting. the flange 311s sllght f curved yawav'from the plane of.thevwh'eelfto` prevent l l abrasive action'between the flange and-thef` track. An outer flange 5 surrounds the inner edge ofthe opening formed in the plate 4and 65 is apertured toreceive the' outer endsof'ten-f sion springs (i by means of which the jplate 4 is centralized and held in normal position 'i and made vieldable A series of openin s 7 are provided near the outer edge of the p ate 4 and are spaced apart a uniform distance to receive the bolts or fastenings 8 by means of which the plate 4 and confining ring 9 are held in place.. A ring 1() is fastened to the l same side. of the. wheel 1 the plate 4 and is 75 aperturul to receive the inner ends of the tension fapring said ring being secured to the wheel by means of bolts 11-or other suitable fasteliings.

Inasrauch as car wheels have their sides east hollow or made concave it is necessary to provide a support or filler 12 for the inner portionjof the plate 4. The support 12 consists of'a plate of annular form having its outer edge portion reeurved, as at 13, to t v` against the curved portion near the outer edge of the hollow side of the wheel so as to brace the plate 12. The inner edge portion of the .plate 12 is secured to the thickened central portion of the wheel by means'of the 90 l fastenings 11, being apertured to receive said fastenings and confined between the ring 10 andthe central portion of the wheel 1, The outer side of. the plate 12 is flush with the side of the thickened tread portion of -the 95. wheel against which the plate 4 bears, so that said plate4 hasa bearing throughout its extent. The boltsor fastenings 8 have their threaded ends reduced to receive the confining plate f) so that said confining plate is .prevented from binding the plate 4, While at the same time the nuts upon' the threaded ends of the/belts 8 may'be properly tightened.v 'Ihe Aflange 5 at the inner edge of the' plate 4 and the ring 1() provide Vattaching means for 105 opposite ends of the springs 6 and heidisaid springs clear of the wheel 1. The-openings 7 near the outer edge of the plate 4 are sufciently large. to admit of the plate yielding when passing over a rail, frog, or like part touching the. side of the track upon w rich the wheel 1 is moved, thereby preventing QF.inferiY i 1u l means for securing said plate Vto the Wheel llifting of said wheel when thellange'S `meetsl 4 with and passes over said crossing or touchin the rall," frog or like part. r aving thus described the invention, what sion springsA normall Y toholdA it injgiven position and.l adapted to 4 permit the same to yield when passiilllg over Van obstructionwith'out tending' to vWheel y when" passing ver. an obstruction lis claimed 'as newis? withoutbindng the same, and tension s rings normally exerting a`pressure` upon sai plate the 3.
