Tool-post

This tool post was seen in a 1910 catalog from O. K. Tool Holder Co.: "The O.K. Tool Post holds the tool on the side, thus enabling one to get up near to the chuck or face plate. With this tool post the tool is adjusted vertically, thus keeping the clearance on cutting tool always the same. The tool post swings around at any angle..." The No. 1 model, suitable for 14" to 18" lathes, was priced at $10. The No. 3 model, for 30" to 40" lathes, was priced at $30. |

Tool-holder
|
Charles W. Grant |
Derby, CT |
This patent date was seen on a tool holder in a shaper catalog ("Bulletin #46") from Potter & Johnston Machine Co. The patent consists of improvements to patent 677,350. This improved patent was used by O. K. to sue J. H. Williams Co., who had purchased 75 of O. K.'s improved holders and then brought out their own slightly modified version, for which they received patent 1,158,100. The courts held that the field of tool holders was a mature one and that the O. K. patent could only cover the itemized combination of features, and therefore the Williams tool holder did not infringe. |
