Description: |
Rufus B. Fowler - patent attorney
My invention relates to the feeding mechanism of a metal-turning lathe; and it consists in the addition of a driving-pulley to the "intermediate gear" usually employed in driving the "leading-screw," from which a rotary motion is given the "feed-shaft" also, in a gear and driving-pulley driven by the intermediate gear, by which a quicker motion is given to the feed-shaft, and in devices for holding the driving-pulleys, whereby a change of gears may be made-and the speed of the feed-shaft varied.
