Patent number: 5549285Abstract: A wire rope vibration isolator includes a coil of wire rope having a predetermined number of individual consecutive coils, a first crimp bar, and a second crimp bar. Each of the crimp bars is essentially rectangular in shape and has a pair of opposing side surfaces. A series of lateral holes extending from one side surface to the other side surface of each of the bars is provided so that the predetermined number of individual consecutive coils may be threaded through the series of lateral holes of each of the bars. A crimping force is applied to each of the two crimp bars at a point where each of the individual coils passes through a respective bar. The coils are thereby secured in a fixed position relative to one another while remaining elastically deformable. A spring-like quality is thus imparted to the coil of wire rope so that the first crimp bar and the second crimp bar may move relative to each other to dissipate vibrational energy.Type: GrantFiled: April 21, 1995Date of Patent: August 27, 1996Assignee: Enidine, Inc.Inventor: Michael J.
