"Vintage Machinery" entry for Fisher & Norris
|
|
Description: |
| The 1852-04-10 Scientific American had an article on this vise and indicated that it was made by Fisher & Norris. "These vises are... made of the best quality of American cast iron, with the best steel indissolubly welded on to the bit of the jaws; the middle links of the rivets and chains are case-hardened, and the screw-pins, lever, and chain made of best refined iron. This principle of vise was patented, by Mr. Mathews, of Worcester, Mass., and since assigned by home to Messrs. Fisher & Norris, who are now engaged in their manufacture, and have given increased value to the original invention, by improving the form and proportions, and employing their own patent welding process to the jaws..." The patent for the welding process is 5,331. |
