Abstract
HOLES FOR ELECTRICAL CONDUCTOR LINES AND THE LIKE ARE FORMED THROUGH OFTENTIMES INACCESSIBLE WOODEN OBSTRUCTIONS, SUCH AS STRUCTURAL FRAME MEMBERS OF A HOLLOW WALL, BY UTILIZING A NOVEL DRILL HAVING AN ELONGATE SPRING-LIKE SHAFT WITH A DRILL BIT ON ITS LEADING END, AND WHEREIN THE SHAFT MAY BE BOWED TO INSERT THE SAME INTO THE WALL TO DIRECT THE DRILL BIT IN THE DESIRED DIRECTION. THE METHOD FURTHER COMPRISES CONNECTING A PLIABLE LINE (A PULL LINE OR CONDUCTOR LINE) TO ONE END OF THE DRILL AFTER IT HAS PASSED THROUGH THE WALL, AND THEN REMOVING THE DRILL WHILE PULLING THE LINE THEREWITH TO POSITION A LENGTH OF THE PLIABLE LINE EXTENDING THROUGH THE WALL.
