Description: |
| Crosby, Halsted & Gould - patent attorneys
The machine upon which my improvements are based, is essentially a lathe, adapted either to chucking-work, or to mounting it upon centres, provided with a rotating polishing-wheel, to be supplied with fine abrasive powder, said wheel being so arranged, that by changes in its position, it can be brought to operate upon the rotating body, to be ground to any required size, or to be polished, and can also be brought against revolving laps or grinders, by which its acting surfaces and angles are kept perfectly true, so as to produce correct results in grinding and polishing. |
