Improvements in roller side bearings for cars are particu-larly interesting at this time because the necessity of reduc-ing flange wear and flange resistance is more thoroughly ap-preciated resulting from the increasing weights of cars andloads. In a previous issue of this journal the earlier form of thisside l)oaring was illustrated, and we now present engravingsshowing an improved form of the bearing complete and in do-tail. The engravings are sufficiently clear to require little de-scription. This is a development from 15 years experimenting,one idea of the inventor and designer being that It was neces-sary to provide means for compelling the rollers to roll andbring them back to their proper position between the bearingseven when unloaded. The tendency for rollers to flatten unlesscompelled to roll is well understood. There are but five parts to this bearing in addition to the American Pressed Steel Car
