"Vintage Machinery" entry for Kettenring, Strong & Lauster
"This invention relates to an improved boring-tool, which is to be applied to lathes of all descriptions, and which is so arranged that it will be guided and held in the proper manner. The invention consists in arranging a loose collar on the tool, said collar turning freely on it, so that it may be supported in a suitable stand, or in the article board, as may be desired. The tool has thereby a convenient support at or near its working-end, and will be more apt to work steady and true than it would be without the guide-collar."
