` .To all whom it may concern,.-

Be it known that I, HUBERT M. PERRY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Side Bearings forCars, of which the following is a speciiication.4

This invention relates to improvements in side bearings for cars, and refers more specifically to a side bearing of that type in which one or more antifriction-rollers are mounted to traverse Ways in casing-frame, which latter is in turn secured either to the body of the car or truck bolsterin such manner that the periphery of the roller or rollers are adapted for engagement with the op-i posed member of the car structure.

Among the salient objects of the invention are to provide a construction in which acentering-frame is mounted upon and arranged to reciprocate with the roller or rollers and serves to constitute a caging for a spring which is compressed by the reciprocatory movements of the frame; to provide in a device Vcharacterized as` above a simple construction in'which a single spring is made to serve as the means of centering the rollers from both directions; to provide awside bearing the casing-frame of which is constructed in two parts separable from each other in a` longitudinal and vertically-disposed plane or line of separation, thereby facilitating the construction of the parts, theassemblement of the same, and rendering them more readily accessible in case it be desired to take the bearing members apart; to provide a construction in which the disposition of the sprin with reference to the parts acted upon is suc as to secure or approximately secure equilibrium of action; to provide a construction in which'the ways upon which the rollers travel are formed by wear-plates so arranged that they may be assembled. and secured in position with minimum trouble andV cost, and in general to provide a simpliiied and improved construction of the character referred to.

To the above ends the invention consists in g they, matters hereinafterdescribed, and more particularly pointed out in the appended claims.

' In the accompanying drawing, Figure 1 is a horizontal sectional view taken on line 1 Lof Fig. 2 and looking downwardly. Fig. 2 ist a longitudinal sectional view taken on line 2 2 5 5 of Fig'. 1. Fig. 3 is a transverse sectional view on line 3 3 of Fig. l. Figs. 4 and 5 are details in side elevation and plan, respectively, of the centering-frame. Figs. 6 and 7 i are side and end elevations of one of the movable spring-abutments.

Referring to the drawing, 1 and 1f -designate the two main castings, which together constitute the casing-frame of the device. These members are yconstructed to fit to- 6'5 gether along a central longitudinal andvertically-disposed line which is curves toconform to an arc having its radius from the centerof thev car-bolster, so that the casingframe divides in the centerplane of the mech- '7o anism contained therein. Each member is at each end provided with outstanding' flanges, as 2 and 2',- arranged to register with each other and perforated to receive unitingrivets. (Indicated in dotted lines at 3.) The. casing-frame members are so shaped that when united they form an open-topfboxlike casing the upper portion of whichhas interiorly-curved end walls 4 and the bottom of which is formed by two horizontally-disposed wear-plates 5 and 5, constituting ways upon which the antifriction-rollers travel, These wear-plates are mounted to rest upon the base portions 6 and 6 of the main castings and have their peripheral edges let into grooves formed in the respective casing members,4 as indicated at 7 and 7. The wearplates probably lie in the 'same horizontal plane and extend the full length o f the rollerboX, the end margins of the plates being also let into the grooves formed in the corresponding parts of the casing members, as indicated at 8, Fig. 2:

Between thdemeeting faces of the two main castings the parts thereof which lie 95 below the wear-plates are formed longitudinally-disposed registering recesses, as 9' and 9', Fig. '1, which together form a groove or way Within. which extends and reciprocatesA the lowerportion of a centering-frame 10. Theend portions of this groove or way are narrower than the central portion thereof, as indicated in dotted lines in Fig. 1, abrupt abutment-shoulders 9 being formed at tlie ends of the wider portion thereof. w

11 and 12v respectively designate the tw antifriction-rollers, which rollers are of frustoconical shape. being taperedto correspond IOS IOO

" fremthegbolster-aids and arranged within y,thecasing--ame with their axes lin alnement Vand united, with each other by means ofa trunnion of reduced axis member 2 13. Breferablyl the rollers '11 and 1 2 andthe l*l'f'runnion connection therebetween are formed integrally with each other but they may of course be separately formed and the trunnion member: inserted'axially through the rollers'. ycentering-frame is of such width and f tliickness as to iit easily but closely within the 'space between the proximate ends of the two rollers', land lts upper ortion is apertured` and 'constitutes a journa portion 14, which fits up'on the trunnions of the rollers. This journal portion may be made with a removjab'le journal-block 15, keyed in position, as indicated in Fig. '4, ontheframel may be made of material such as malleable iron or ysteel susceptible of being bent and t 4esides of the journal portion bent over to embrace thev trunnion, as indicated in Fig. 2. The lower portion 15 of the centering-frame lconstitutes a s ring-cage, .and to this' end takes theform o 'an opensided rectangular'elon- 5 gated' box within which is seated the center-A 'mg-spring 16. The width or thickness of the `lower part of the centering-frame is less than the comlinedwidth of the central main'porvainstorclosely approach the shoulders 9..

"J enever the rollers and connected centertions lof said-lo (see Figs. 1 and 3 and the proximate edges of the wear-plates are constructed to approach -closel .the sides of the centering-frame, so as to guide or conine the latter 'and overhang the --rec'esses 9 9, as shown clearly'm Fig. 3.

In each end o f the cage lis mounted a mov- 'ablef abutment, as 17 17 which is preferably socketed'to receive the'corresponding end of the .centering-spring; and in the central or normal position of t e ing-frame are reciprocated in eitherdirection,- Ahowever 'that one of the abutments at the rear (consldered with reference to the directioli of movement ofthe roller) .is carried forwardly with `the centering-frame, thereby compressing the spring Vagainst theVV opposite abutment, which at this time is held'iminovlable by engagement with the o pos'ed shoulders 9. Vice versa, when' t e-.rollers are moved in the o posite direction the previously-movable a utment becomes stationary. land the othenabutment'serves to compress lthe' spring, thusv return. or centering 'tudinal recesses 9,' and `9,

action 'of the spring upon the rollers inboth directions.
