Abstract
409,224. Taps. HELIN, E., P.O. Box 3087, Stockholm. Oct. 27, 1933, No. 29854. [Class 83 (iii).] A tap for nuts having a curved centre axis has a tapering cutting portion of length less than the depth of the nut to be cut, the base of the tap having a radius equal to that of the nut thread and the top of the cutting portion a radius equal to or less than that of the nut thread reduced by the projection of the nut curve on the face. The normal to the curve of the nut thread at C parallel to the face may or may not be central of the nut ; the tap has a contour similarly curved to that of the thread to be cut and is of a length equal to or less than the shortest distance between the normal and the nut face, the radius a of the base of the tap is made equal to that of the thread to be cut b, while the radius at the top C is made less than this dimension by an amount equal to the smallest projection DA of the nut curve between the normal and the nut face.
