Description: |
| Now, the chief object of my invention is to supply the lathe man or machinist with a chuck which, when applied to the ordinary iron lathes in use, shall be first, adjustable to bolt-heads of different sizes; second, a chuck that will adjust itself to the bolt head, whether the same is either concentric or eccentric with the body of the bolt to be turned; third, a chuck adjustable to accommodate itself to a long or short lathe-center; fourth, a chuck that can be rendered both rigid and movable for doing peculiar kinds of eccentric work. |
