Abstract
Improved pipe unloader, characterized by being made up of a braided metal cable, or of similar suitable material, of suitable length, which at one end, that of attacking the pipe, has a spiral spring that facilitates and guides the penetration of the device into the pipe especially for the curved portions thereof; and the opposite end of said cable carries a spherule or the like which serves to pass the electrically conductive wires through certain points where required.
