Manufactured by O. K. Tool Holder Co. - Shelton CT
Assigned to O. K. Tool Holder Co. - Shelton 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.
