ABSTRACT:
A new method and apparatus for quickening in the insertion of a fish tape through a conduit by reducing the occurrence of frictional adhering. The apparatus provided in several embodiments uses flexible lubricant carrying materials having pressure sensitive fluid release characteristics affixed to the free end of a fish tape. The apparatus is saturated with a fluid lubricant prior to being inserted into an opening of the conduit and pushed. As the pressure sensitive material enters a bend in the conduit, pressure is applied to the pressure sensitive material by the long radius wall surface of the bend causing lubricant to be released. The possibility of frictional adhering of anything being pushed through the bend is greatly reduced. The apparatus moves past the well lubricated area and is immediately followed by the body of the fish tape. In the event frictional adhering does occur between the fish tape with attached lubricant spreading apparatus and the conduit, permanent hookable loops are provided to allow easy hooking and pulling of the apparatus by a second fish tape.
