Abstract
A magnetic wire pulling system advances wire through a house or other structure around obstacles with a string tied to a pulling cord then tied to the wire. The system has small, medium, and large magnets, and tools attracted to the magnets. The round small and medium magnets are tied upon strings wound upon spools. The spools have pins to secure magnets. The tools comprise a retrieval tool, a manual release tool, an insertion tool, an automatic release tool, a transfer tool, an extensible prop, and a telescoping pole with magnet. The tools deliver a magnet into the structure of a house, retrieve a magnet from the structure, or transfer a magnet from one tool to another tool. In operation, a bigger magnet attracts a smaller magnet or a magnet attracts a tool to advance a string beyond an obstacle to continue pulling wire.
Claims7
A system for pulling wire through a house or other structure with a string tied to a pulling cord then tied to a wire wherein the improvement comprises:
- one or more small magnets having said string, an eyelet, and a small spool, said small magnet having a generally round cylindrical shape, a top face and a bottom face said faces marked to indicate polarity, and a groove centered upon the circumference of said small magnet, said string being tied and secured around said groove at one end and around said eyelet at the opposite end and stored upon said small spool;
- one or more medium magnets having said string, an eyelet and a medium spool, said medium magnet having a generally round cylindrical shape of greater diameter than said small magnet, a top face and a bottom face said faces marked to indicate polarity, and a groove centered upon the circumference of said medium magnet, said string being tied and secured around said groove at one end and around said eyelet at the opposite end and stored upon said medium spool;
- one or more large magnets encased in a covering, said large magnet having a generally round cylindrical shape with rounded edges of greater diameter than said medium magnet, a top face and a bottom face, said faces marked to indicate polarity;
- and,
- one or more tools attracted to said magnets;
- whereby a bigger magnet attracts a smaller magnet or any of said magnets attract a tool to advance said string beyond an obstacle in said structure.
