Abstract
174,454. Howe, W. J. Oct. 29, 1920. Stud-boxes.-The sleeve 13 of a stud-box is cored internally to engage the correspondingly tapered split-nut 9, which is closed to grip the stud by means of the end pressure of a screwplug 17. The latter is screwed with threads of opposite hand to those on the stud, and may be hollow. The split-nut, which may be plain to engage the unscrewed portion of the stud, mav be feathered in the sleeve and may be recessed as shown in Fig. 3.
