Description: |
| "Our invention has for its object to connect and disconnect the feed of lathes, &c., in a more simple and efficient manner than has heretofore been accomplished; and it consists in the employment of peculiar swivel or 'union-jointed' nuts, so arranged in connection with friction-clutches that the gears which operate the side and cross feeds may be instantaneously thrown in or out of action, as may be required."According to Leander Bishop's "A History of American Manufactures from 1608 to 1860", this patented lathe feed gearing was used on all lathes of that era made by Putnam Machine Co. |
