Abstract
A swivel arrangement especially suitable for connecting the back end of a reaming tool to the front end of utility cable during installation of the latter underground is disclosed herein. This arrangement includes a swivel mechanism which is smaller in cross-section than the reaming tool and utility cable apparatus, for connecting the swivel mechanism to and between the reaming tool and utility cable, whereby to create an axially extending radial gap between the tool and cable. In accordance with one feature of the disclosed swivel arrangement, one end of the swivel mechanism is fixedly connected to the back end of the reaming tool to prevent relative lateral moement between the tool. In accordance with another feature, the arrangement includes apparatus no larger in cross-section that the remaining tool and substantially equal to or larger than the utility cable extending around at least a substantial axial segment of the swivel mechanism for reducing the axial extent of the radial gap between the tool and utility cable.
