Patent number: 8057144Abstract: A sealed attachment fastener assembly with a receiving member and a cap that can be inserted into an opening in a work piece and fixed therein from only one side of the work piece. A portion of the fastener assembly on the blind side of the work piece is collapsible into a flange. In addition, another portion of the fastener assembly is contemporaneously radially expandable within the opening of the work piece to at least rotationally secure the fastener assembly with respect to the work piece. The radial expansion will result in a high interference fit of the fastener in the work piece, which may enhance the fatigue of the installation. A cap completes the fastener assembly to substantially prevent fluid from leaking through the fastener assembly opening. The cap can be assembled with the receiving member after the internal threads within the receiving member have been machined.Type: GrantFiled: August 27, 2004Date of Patent: November 15, 2011Assignee: Fatigue Technology, Inc.Inventors: Timothy H. Johnson, Leonard F. Reid, Bruce F. Gibson

Patent number: 5405228Abstract: A circular opening (54) is formed in a wall (12). A tubular shank (42) of a nut mounting unit (40) is inserted into the opening (54). The unit (40) is moved endwise to place a nut cage base (46) against the wall (12). A split sleeve (82) is installed on a small diameter portion (90) of a mandrel (M). The mandrel (M) and sleeve (82) are inserted into the tubular shank (42) from the side of the wall (12) opposite the nut cage (44). The mandrel (M) is then retracted to successfully move increasing and maximum diameter portions (90, 92) of the mandrel (M) through the split sleeve (82). The mandrel portions (92, 94) exert a radially outwardly expanding force on the split sleeve (82). The split sleeve (82) in turn imposes a radially outwardly expanding force on the tubular shank (42). This causes a plastic deformation of the tubular shank (42), creating a tight interference fit between the tubular shake (42) and the sidewall of the opening (54). In this manner, the unit (40) is firmly secured to the wall (12).Type: GrantFiled: March 16, 1993Date of Patent: April 11, 1995Assignee: Fatigue Technology, Inc.Inventors: Leonard F. Reid, Eric T.
