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 supported engine powered handle while the shell is being spun at a high speed on a vertical axis, free line ends being 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 housing shell comprises two like die cast halves which abut each other in a medial radial plane with which the line feeding windows are symmetrically related. Each window is formed by two matching notches including four cups enclosing opposite ends of two tubular closely parallel line guiding rollers. Cast integrally with the four cups are four co-axial stub shafts on which the hollow rollers are centered internally.
O-ring means retain the rollers interlocked with the integral stub shafts on a selected one of the housing shell halves thereby making upwardly extending halves of the rollers available, when assembling the housing shell and spool, to receive and guide the line ends peripherally aligned with and extending radially through the shell housing windows.
