Abstract

169,381. Drummond, T. H. Sept. 8, 1920. Screwing die-heads.-A die-head consists of a tubular body 1 which is screwed at 2 to receive an adjusting-nut 3. The dies 7 have grooved sides to fit the bevel-guides 5 on the body and radiused bevelled ends 8 to fit the conical end 9 of the nut 3. By screwing down the nut the dies 7 are brought together. The body is paned at 10 to fit a wrench.
