Description: |
| "My invention relates to that class of machinery commonly known as 'screw-machines,' a form of lathe in which the work is held in a chuck and operated upon by various tools fixed in a rotary turret mounted on a carriage sliding in the bed of the machine in line with the axis of the spindle which carries the chuck, and also by tools fixed in tool-posts carried by a second carriage sliding at right angles to the first. ... The essence of my invention rests in combining with the carriage a screw-feed of peculiar construction capable of being thrown instantly out of action, and an independent feed for imparting a longer and more rapid movement..." |
