Abstract
A cable pulling eye assembly comprises a spike (16) having an auger thread (18), a coaxially mounted shell (36) and an eye (31) with a threaded opening (34), which is mounted on a threaded rear section of the spike. The eye is rotated by a power tool to advance the auger into a bundle of wires (11) of a sheathed cable (10). The shell is subsequently crimped to further force the wires into the flute defined by the auger thread. A pulling steel cable is attached to the eye to draw the cable between telephone poles or through an underground conduit.
Claims2
A cable pulling eye assembly, which comprises:
- a rod having a square auger thread formed along a forward section thereof and a screw thread formed along a rearward section thereof;
- a cylindrical shell means having a closed nose end with an opening therethrough for receiving and supporting said rod in coaxial relation with said shell;
- an eye member having a threaded bore for threadably receiving the threaded section of the rod;
- and
- a jam member on said rod positioned within said shell means and jammed into engagement with the inner wall of the closed end of the shell by the eye member being screwed on the threaded rearward section of the rod into engagement with the outer portion of the closed end of the shell means.
A cable pulling eye assembly, comprising:
- a cylindrical shell having an open end for receiving a sheathed multi-wire cable, said shell having a second closed end with an opening therethrough that is coaxial with respect to the axis of the cylindrical shell;
- a rod mounted in said opening and coaxially positioned within the shell, said rod having an auger formed along a leading end section and screw threads formed along a trailing end section which extends through said shell opening, said auger having a thread which defines a single flute;
- a jam member secured to the rod within the shell for engaging the inner surface of the closed end of the shell;
- an eye member having a threaded bore for receiving the threaded screw section of said rod and for turning the rod to advance the auger into a multi-wire cable positioned within said shell and to draw the jam member against the inner wall of the closed end of the shell when the eye member is advanced to apply a force against the outer wall of the closed end of the shell;
- and
- said shell having indentations to deform the wall of the shell to force the wires into the auger flute.
