ABSTRACT:
A line supply spool rotatably confined co-axially within a thin housing shell having a splined mounting on a polygonal arbor through which said housing shell is supported at the lower end of a manually held engine powered handle while the shell is being spun at a high speed on a vertical axis. Free line ends are progressively fed peripherally from the spool through equally spaced windows provided in the housing shell by controlled rotation of the spool relative to the housing shell, the control of the rotation of the spool being optionally effected manually while the tool is shut down or automatically while the tool is spinning, the election being made by a minor selective shifting of a few parts, this election being readily reversed, whenever desired.
