Abstract
A spring-loaded wedge dead end for use in electrical transmission lines has upper and lower jaws which close upon one another in a wedging action to grasp the dead end of such a line. The wedge dead end includes a U-shaped clevis for use in attaching it to a pole or the like, and upper and lower jaw guides which form a U-shaped channel in which the upper and lower jaws are disposed. The jaws are spring-biased toward a closed position, are coupled so as to move in a corresponding manner, and may be locked in a fully open position, from which an installer may release it when an electrical transmission line is correctly placed between the open jaws to simplify the dead-ending of the line.
