Turning-lathe

Warren Aldrich |
Lowell, Middlesex County, MA |
The object of my improvements is to construct an apparatus by means of which a variety of different forms, such as globes, ovals, etc., can be readily and accurately turned on the same lathe. To effect this result, the tool carriage, in which the tool is placed, is susceptible of a variety of motions and adjustments, by which it can be moved in any direction necessary to the production of peculiar forms and adjusted in any desired position with regard to the center line of the lathe. This arrangement is also so contrived that the tool carriage can be moved by hand or be fed by the gears of the lathe. |
