Abstract

275,851. Wilberz, J. Dec. 21, 1926. Screwing. - In a screw-cutting machine for tubes, the work 11 is mounted in a rotary chuck 4 and is acted upon by dies 3 carried by a sliding frame 1. A spindle 5, rotatable by a hand wheel 7, carries a head 6 which expands jaws against the interior of the tube, the spindle also carrying an interchangeable threaded sleeve 8 for engagement with a clasp nut 9 operated by a hand wheel 10 so as to impart feed to the frame 1 on rotation of the disc. Tapping.-The dies may be replaced by dies acting on the interior of the tube.
