ABSTRACT:
A portable lathe is disclosed which has a compact arrangement of an automatic tool feed mechanism which facilitates the use of the lathe to machine an internal surface of a workpiece. An automatic cutting bit feed is located diametrically opposite the cutting bit holder and is connected to it by one or more rigid connecting bars. The bars transmit the feeding movement from a feed slide to the cutting bit holder across the face of the rotating cutting head. A feed screw is attached to an overrunning clutch which is advanced through contact with an actuating arm during each revolution of the cutting head. A clutch nut is provided on the feed screw to release the feed slide and the cutting bit holder from the feed screw to facilitate manual manipulation of these elements. The rate of feed may be adjusted by adjusting the stroke of a cam and overrunning clutch associated with the feed screw.
