Adjustable Device for Dressing Down Bearings
Patent for a tool that dresses down bearings. Railroad engine journals and their corresponding bearings show wear over time. When replacing bearings into such a journal, without adaptation of the bearing there will be an improper fit, resulting in "hot journals" or "hot boxes". This tool adapts a bearing to a proper fit for the journal into which it will be installed.
