SIDE BEARING ron cans.

T all whom it may concern:

citizen of the United States, and a resident bf Chicago,'in the county of Cook and State of Illinois, have invented certain new and useful Improvements in SideBearingsfor Cars; and'I do hereby declare that the following is a fulh-clear, and exact description lh'c'reof, reference being had to the accompanying drawings, and to the letters of ref- ;erence marked thereon, which form a part I of this specification.

My invention relates to certain new and hs'eful improvements in antifriction bearings, as side bearings for cars and other I purposes, and-its object is to produce a de vice of this class which shall have certain advantages which -will appear more fully and at large in the course of this specification. l

tain novel features of construction which are clearly illustrated in the accompanying ilrawings and described'in this specification.

In the aforesaid drawings, Figure l is a,

side bearing box.

Referring to the drawings, A is the main portion of the bearing box or carrier, and its form will be readily understood from the illustrations thereof. It will be seen that. this boxis rectangular in shape, open at, top 'and bottonnund may be provided. with lat erall extendin erfforated ears a. as shown ,in the drawing, by which it can be secured to the body sapporting member of the car or other structure. The lower portion of the ---'-box is preferably curved. The sides of the box are channeled out at (1, these channels running longitudinally of the box, and having upward extensions a at the center. The bottoms of the channels a constituting tracks or flanges, it will be seen, slope down slightly towardtheir centers, the purpose of which-will be presently apparent.

' roller B is passed into the box, through the rivets c which pass through flanges a. .formed upon the end .walls of thebox, as herein illustrated. The box or carrier fits against the part to which it is attached in such manner that the wear plate or cover will be held in place between said part and the carrier whether the rivets c be present or not; but the rivets hold the parts assembled for purposes (if shipment. The bottom side of the cover thus affords a track or tread for the roller at'the upper side of the box. The cover or wear plate C also-serves to confine the roller in the box, it being ap parent from the drawing that a portion of the wear plate bears such relation to the roller and to the notches or extensions roller is being inserted into or removed from the box that the roller can not be removed and is therefore locked in the carrier when the cover or wear plate is in place, but is free to be removed when the wear plate is removed. The said cover or wear plate is so arranged that itmaybe reversed so that -when the lower side thereof is worn by engagement with the roller it may be turned over or reversed to present a new tread surface. to the roller. r

The-operation of this device will be readily apparent. The bearing is secured in place on the body bolster or other part which carries the same, as are bearings of the same general construction, and when any weight tacts with the cover C and rolls back and forth thereon; When, for any reason, the bearing is'raised, and the roller happensto be oil the center of the bearing box, it rolls to the lower portion of the same.

I realize that considerable variation is possible in" the details of this construction without departin plate C, which may be secured in place by through which the gudgeons pass when the.
