Abstract
677,113. Screw-cutting dies and taps. KUMMEL, R. Sept. 21, 1950 [Sept. 21, 1949; Oct. 28, 1949; June 1, 1950], No. 23171/50. Class 83 (iii). A die, tap or chaser, for a length approximately equal to the diameter, has a straight or curved conical portion on which the threads 11 are of the same depth as the full-cutting threads 40 and act as axial guides; additional guide faces, 7<SP>1</SP>, Fig. 4, and 16, Fig. 7, are also provided and may be adjustable to accommodate small variations in the diameter of the work. The adjustment of the guiding faces is by slotting the tool longitudinally or helically in the region of the faces and, in the case of a die, providing a screwed cap 19, Fig. 7, with a cone surface 20, or a taper-threaded cap, and, in the case of a tap, providing a slidable or screwed mandrel extending through the tap. A slotted die is also described, having adjusting screws 22, Fig. 10, and and a regulating screw 23 covered by a plate 24 which rests resiliently on the screw 23 and has flanges 26 gripping the adjusting screws. The The tool body may be made as a separate part with steel blades pressed into it or it may be cast round dove-tails on the roots of the blades.
