Description:

Improvements to the bearing-ball retainer of patent 604,678. The inventor was the founder and owner of Champion Blower & Forge Co.; we have a report of a drill press, identified as "Hill, Clarke & Co." and containing bearings with this patent date plus a star logo. We assume that the assignee manufactured the bearings. As for Hill, Clarke & Co., they were a dealer rather than a manufacturer and it is most likely that the drill press was made by Champion Blower & Forge Co.
