(01. 'it zit) My-invention i'elatesto a "railway ear truck and especial-1y to a form of connection "between a journal box commonly associated with the journal end of a wheel and assembly and a frame memher which normally may be supported thereon.

- A general object 'of my invention is to forth a simple form which may Teadiiy be adapted to *a usual form-of connection between the journal 'o'oX and the-"associated frame member.

My "invention "contemplates a mm-e member having z edes't-a l jaws between which may" be sup ported in the usual manner a journal box, said jmii'nal box forming in uevice as illustrated support means for said frame tfii'oujg h the medium of a spring group superposeiio'n t'he joui nal box. I

My invention -comp1ehends an ajirangement of such a journal box and suppoi ted frame Iriefifltir wherein a plurality "of friction-shoes =r'iiay be ported h'om the journal box for hi'oticirial 'ngagement 'with the pede'stal legs of the submi ted frame member. 'As-devised, my novel arrangement affords friction engagement for inb'oaidaffd outboard portions of the frame 'mei'nheT at upposite sides of the journal 'b'dx strueture. 1

As illustrated; m3 hovel structure ass-i215 jiesilient resistance to relative late ial motion between-the frame mernlierand the jfourha l "b'o'X and frictional as well as resilient re oe to rel ative vertical movement btwh th her and the journah'box as wen *as-fiiotional and 'resilieritnfesistaiioe foraif Eiis'iiahce to r'eiati've movement longitu'tii of the max between the qidurnai and the fiasie member. l ne principal TOm'i'atioh of the ho'vvever, is an resti'ict with oert elin li 't's or eon'crol by 'ii'fans of "the assessment tion, re fife vertical hitiveifie'iits heathen t-he 156K and tlie isifi -ported -frame member. l

Describing my novel 5 otiire in "iijtail, the embodiment shown eoii'riifises a tfuck F'frsiifie memb'er generally assighateu z, *dni a 'frag 'menta-ry end portion of. which is shown, said with a relatively flat top portion serving as aseat for the spring Hi superposed-thereon, said spring being confined between the inboard and-outboard areuate walls I8 and 20 of the -f-rame,-said walls being cored'ayvayas at 22 and headed therearound as at "2 1 to afford. a convenient means ofi-nspection for the enclosed spring, the upper end of said spring being afforded a seat against the top wan '26-.of 'saidirame member. The-inboard e'iidof the journal box is formed with the usual dust g arai'port cn 2 8,ands'aid box is jformed with 'in'boa'r'd guis flanges so, "so and outboard guide flanges .32, opens-aging 'ihboard and outboard wear 'prate sur'iaces on said trainees indicated TBSDECiGiVW 21134 and 3 5 atopposite "sides of Said ramb e-1am.

'fs'efiing "a sim ar jourp'os'e. The view'oi Figure 3 f'shows alseetio'n through 1505;. fiournal box I; is afioriied the usual form of iii; .38 hinged at its upper ncl as at!!! in the usualinanner,

fjnitsjoutboa'rd iaoe, the journal 'box 1'4 is formefi with wine 'poiti'onsfl and. '44 at opposite sides of the box, eac'h ofsa-idwing portions merging with the adjacent "peiestalgiiide flange and being formed as an integral shallow rectangular housing opening inwardly and serving as 'a. convr'i'ient "ieicefitaole ror m "novel form oi-friction "d'ifiee. ilikeuiise, on the inboard fa'eeof the box they "be formed at oppbsitesides thereof wing portions {(8 and -61 structure similar to the portions fat the outboard side of thebox and theiielestal iiaw is of the frame "member, said seesaw jaw haiiing "ihfilfat plane a general U- s'eo'tion "with the inboard leg 52, the outboard *leg 5}, and-themain Web {5 6 joining said flanges as shown; Said peqes'ta'l leg '8 "is providefi with a easing or Wear plate -58 with inboard an'a outboard plate portions designated respectively '34 and against which inboard and outboard guide flanges 30 and 32 "'of the journalbox may' nga e as ai eau escribed, Within each shallow housiiig 42, 11 anti so maybe positioned a Ir-ictibinsho'e 30, said shoe being "2, 'Shallow Clip of rectangular form with a flange 62 extending entirely therea-round to define the cup structure of the shoe within which may be confined the resilient member or rubber spring 64, said spring likewise having a generally rectangular form somewhat smaller than the shoe within which it is enclosed in order to permit lateral expansion as the rubber pad is compressed. As shown, the rubber pads or springs 64, 6A are under some compression and the degree of this compression may be varied to modify the amount of friction developed at 66, 65 along the engaging friction surfaces at the backs of said shoes and the opposed wear plates which are mounted on the adjacent pedestal.

It will thus be seen that I have provided a novel arrangement of friction means at spaced areas around the journal box, said areas serving as control means to restrict the relative movement which may take place between the supporting journal box and the supported frame member between whose pedestal jaws said box may be confined. It wilfbe readily understood that the degree of friction developed may be modified by varying the character or size of the'rubber pads or resilient members housed in each of the friction means as well as by modifying somewhat the character of the frictionally engagin surfaces on'the shoes and the side walls of each pedestal.

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown which is merely by way of illustration and not limitation. as various and other forms of the device will, of course, be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
