ABSTRACT:
A turnbuckle for a tensioning cable includes a casing forming a cavity. An internally threaded nut is mounted to the casing at one end of the cavity, the nut being rotatably and non-axially movable relative to the casing. An externally threaded bolt is threadedly mounted in the nut and projects into the cavity. The bolt is axially and non-rotatably movable relative to the casing, so that rotation of the nut produces axial movement of the bolt. The casing and bolt have a radial slot formed at adjacent ends thereof, opposite the nut, for attachment to a tensioning cable. The bolt includes a radial cam at each end thereof, each cam having an axially extending first stop for engaging cooperating second stops formed at axial ends of the nut to terminate rotation of the nut when the bolt is at either end of its stroke. The nut includes a recess formed in an end thereof disposed remotely of the casing. One of the cams is movably disposed in the cavity of the casing, and the other cam is movably disposed in the recess of the nut.
