Abstract
676,078. Screwing-dies. DESCOMBES, C. Feb. 9, 1951, No. 3224/51. Class 83 (iii). The upwardly-tapering resilient branches 2 of a screwing-die are adjusted by a screwthreaded ring 5b which is prevented from rotating by a lug therein engaging a notch in one of the branches, and is drawn back by a nut 7 with a flange 9 engaging a groove 4 at the base of the branches. In a modification, Figs. 8 and 9 (not shown), the resilient branches taper downwardly.
