rIhis inventionrelates to improvements in anti-friction bearings. y
One object of the invention is to provide a simple, practical andeicient anti-'friction bearing, especially adapted for railway car side bearings, in which the parts are lso ar v ranged that the anti-friction element is automatically returned to normal centerediposcition when tree from load.
.cylindrical roller yinterposed i. between 'the' body and truck lholsters of the car, together with centering means which t about the eX- terior surfaces ofsaid roller and are conmanner as to partake of the relative movement therebetween, said centering means ben ingso formed as to permit limited independent. movement of said roller withrespect thereto under operative conditions.
.Other objects and advantages of the ini-i@y vention will more clearly appear tromthe v description and claims hereinatterfollowing.
' In the drawing forming a part of this specificatiomlig. l is a fragmentary. :front elevational view ot the body and truck bolsters of a railway car, showing my invention inV position with respect thereto, the center sill of the car and cover plate being shown in section. Fig. 2 isa top lplan view of the sidebearing showing the same detached from the body and truck bolsters. And Fig.
l3 is` a part elevational, part sectional view of the invention substantially upon the line {S-3 otFig. 2, and showing a'traginent of y'the truck bolster in section;
VIn lsaid drawing 10 denotes a truck bolster,
and 1l thebody bolster otja railway car,
said holsters being adapted to have relative radial movement in opposite directions. due
vided witha bottom wall 14 forming abearing surface for `the anti-friction element,
and withvspaced vertically disposed ribs.
15-l5, which are arranged iii substantially parallel relation, and between which the anti-friction element is adaptedA to be dislmentv acrossxthe bolster AlO.
A more particular object of the inventionv Y roller is preferably posed, said ribsproviding a guide-way for guiding the travel. of the anti-trictionvelel- A The bearing member 13 also'incluudes an integral centrally disposed flange 16 providing a securing lug at the outer .side of the bearingwhich is utilized as a securlng lug, there being Ya rivet 17 extending through the iiange 16 and the top plate of the truck bolster l0. .At the` inner side of the bearing member there Aare located adjacent the ends of the bearing i provided extensions 1 8-18 spaced apart and tendingtlierethrough for securing the truckn 5 Y bolster-10, said rivets being, indicated at 19` in Figi?.4 i
Preferably formed" intermediate the eX-j an elongated `upstanding boss20, saidr boss ybeing'provided with a vertically arranged, `opening-2lwhich is somewhatl elongated' and extends longitudinally with referenceto the bos's20.A f
An anti-friction,".roller isv` provided which is truly cylindrical in cross section,
"and of a length slightly lessthanthe width surface. of the bottom wall let between the ribs 15p-15, and to be guidedby said lribs during its movement. rlhe radius of said height of the guide ribs I5 i5.

Said transmitting member is preferably oiu one piece construction, elongatedl in .orm.
land is provided with an angular portion 26 adaptedlto t into the aperture 2l ofthe boss.-
QOso asto provide a pivotal connection of said transmitting member with said bearing member.r The transmitting member extends outwardly in a horizontal direction from the pivot, and at its outer end is provided with an upstanding pin 27, adapted to tit into an diat-e the ends of the'transmitting member,
y opening 28m the body bolster l1;V Intermef 4110 ieeyf and kadjacent the pivotal connection of the same with the bearing member is a frame vor yoke portion of the transmitting member which-fits aboutthe anti-friction-roller 22.l `The frame portion comprises side members 29-29 and 'end members 30-30, said side and end members being arrangedin substantially rectangular formation and adapted to fit over the exterior surfacesl of the anti-fridtion roller 22, so that swinging movement of `said transmitting member' will effect movement of the roller 22 when free from load.
The side bars 29H29, as well as'the end members 30-30 are convex in" formas indicated at 3l`so as to provide curved surfaces for engagement with the roller 22 andtopermit swinging movementl of the .transmittingV member with reference to the roller22 while the latter travelsin a substantially straight line transversely across the bolster 10.
VIn operation, .whenthe -body and truck bolsters approach, the bearing member 24' "comes into Contact with the roller 22, andv upon. relative .Y horizontal movement between the ends of the body and truckbolsters, the.V
roller 22is moved to either side of central position. This movement of the bolsters ef'-v fects fa corresponding swinging movement of v the transmitting member 25 vupon thepiv- Votalmconnections thereofV with the bolsters,l e 'the swngingmovement of the yokewith ref-` erence to the vroller 22 which is travelingin a` substantiallyy straight line being permittedby the curved engaging surfaceslof the yoke portion.v 1When the bolsterV portions separatevertically and so freethe roller 22,
.movement ofthe bolsters I0V and 1I to their normal vertically superposed position, will carry the transmitting `member 25 therewith fand simultaneously return the roller 22v toa,
, central' positionwith reference to thebearing member 13,'the posit-ion ofthe transmitting member 25, 'and consequently of the l" roller 22 being controlled atfall times by the vrelative possitionof the bolsters vl() and ll1.
'By the above described arrangement, it
, should be appreciated thata plainsolid anti# vfriction element may bentilized with consid;
era-ble increase inrstrength, and that due Vto the arrangement kof Vthetransmitting inembeif, the roller is relativelyfreewthereof per# ,emitting swinging ofthe transmitting membenwhile the roller travels in substantially Y a strai'glitzpath, thus permitting all necessary movements of the roller while controlling' the position thereof dependent upon the position of the holsters, so that the roller at all times is in the proper position toperformL its funetions'and is centered and held in assembled relation with the bearing by meansv of the transmitting member.
,A c While I have herein shown and described what I now consider the preferred manner of carrying out my invention, the same is merely illustrative and I contemplate all changes and modifications that comewithin the scope of the claims appended hereto.
