ANTIrRIcrIoN BEARING;

Application filed February- This invention {relates to anti-friction bearings; a V I Oneobject ofthe' invention 1s toprovlde a simple, practicaland etficient anti-friction bearing/especially adapted'for railway car side bearing -in which the parts are so =arranged that the anti-friction elements are position when freeifromdoadp I I Another" object of the invention is to 'provide a: bearing of the above mentioned character r including a housing 1 provided "with spring containing pockets at. each end thereof, and'anf anti-friction roller adapted to 5 move back and forth" in the housing, in
