Patent number: 8215886Abstract: A termination system which attaches a conventional threaded rod or bolt to a cable. An anchor is attached to an end of a cable using known techniques—such as potting. A threaded rod or bolt is placed on the anchor, pointing away from the direction of the cable. The rod or bolt is mechanically attached to the anchor using several different techniques. The result is an anchor assembly including a threaded protruding shaft. Because the assembly uses an inexpensive prior art rod or bolt, the machining operations are confined to small components needing relatively little material removal.Type: GrantFiled: October 26, 2009Date of Patent: July 10, 2012Inventors: Richard V. Campbell, Kevin J. Barefield

Publication number: 20090092462Abstract: Disclosed are several clamps and a method for installing the clamps through at least two work pieces from one side. The clamps include a shank, a spacer, a core bolt and an expander. The shank and expander are keyed to together with the expander engaged on the core bolt such that rotation of the core bolt can bulb the expander to form a clamp surface on the blind side of the work pieces. The shank and spacer are temporarily held apart until the expander is bulbed wherein the shank is allowed to enter the spacer to clamp the work pieces. Subsequent over torque of the core bolts fractures a weakened portion of the core bolt permitting removal of the clamps when desired.Type: ApplicationFiled: April 7, 2008Publication date: April 9, 2009Inventor: John D. Pratt
