Description: |
| The rights to this patent were assigned to the inventor's firm, Seneca Falls Mfg. Co. A 1930 appeals court lawsuit (see link) says that "plaintiff's drill chucks, referred to as 'Magic,' were first produced and sold in 1901, and continuously thereafter...under protection of letters patent No. 692,988, granted February 11, 1902, the patent being known as the Davis patent, which had been acquired by plaintiff's predecessor", that predecessor firm being the Modern Tool Co. of Erie, Pa. That same court document notes that on 1922-07-14, that firm was acquired by the appellant, the Consolidated Machine Tool Corp.; we do not list that firm as a manufacturer because this patent had already expired. |
