Abstract
The present invention is directed to an apparatus for distributing a cable-pulling composition onto a cable as it is being pulled through a conduit. In one embodiment, the cable pulling composition is a block of an enhanced composition, e.g., consisting essentially of boron nitride that facilitates the pulling of cables through conduits. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface through the use of the cable-pulling apparatus of the invention.
Claims19
An apparatus for lubricating a cable comprising:
- means for dispensing in a powder form onto a surface of said cable a lubricating composition in the form of a stick, block or wand, the composition comprising a cable-pulling effective amount of an active ingredient for lubricating the cable;
- means for distributing the composition containing the active ingredient onto the cable.
An assembly for drawing a cable through a conduit, the assembly comprising:
- a supply of cable;
- a cable lubricating mechanism for applying a lubricant onto the cable as it is drawn through the conduit, the cable lubricating mechanism comprises at least a means for dispensing in a powder form a composition containing a cable-pulling effective amount of an active ingredient for lubricating the cable being drawn through, and at least a means for distributing the composition containing the active ingredient onto the cable being drawn through the conduit;
- a cable pulling mechanism for intermittently gripping the cable and pulling the cable through the lubricating apparatus at a predetermined rate of speed in response to the movement of the cable through the conduit.
