Abstract
Abstract A power driven tool for driving a flexible plastic rod or tube through a conduit for connection to a conductor wire and then pulling the flexible rod or tube with conductor wire attached thereto through the conduit. The flexible rod is driven by a rotatable friction drive such as a pulley or spiralling pulley in which the rod is wrapped around and driven through a flexible guide conduit for guiding the rod into an electrical conduit. A storage container is provided with a cone spool for storing the flexible rod.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
An apparatus for drawing conductor wires through conduits comprising in combination: a. flexible rod; b. flexible rod storage container for storage of said flexible rod; c. rotatable friction drive means having said flexible rod wrapped at least partially therearound; d. flexible conduit guide means operatively connected to said rotatable friction drive means for guilding said flexible rod from said rotatable friction drive means into and out of a conduit; e. power means for rotating said rotatable friction drive means to draw said flexible rod from said storage container past said friction drive means and through said flexible conduit guide means; and f. conductor coupling means attached to the one end of said flexible rod for attaching a conductor wire to be drawn through a conduit. therearound
