ABSTRACT:
The level winding reel mechanism comprises a frame, a winding reel rotatably mounted on the frame, a line connected to the reel and adapted to be wound thereon, and a pulley rotatably mounted on the frame for guiding the line to the reel, the pulley having a peripheral groove therein for receiving the line, the reel having a stepped hub comprising first and second cylindrical portions having first and second different diameters with an annular shoulder between the first and second portions, the first diameter being less than the second diameter by an amount corresponding generally with the diameter of the line, the reel having first and second end flanges projecting radially from the ends of the first and second portions of the hub, the hub having anchor means therein for anchoring one end of the line, the first portion of the hub having an entry hole therein for receiving the line, the entry hole being adjacent the shoulder, the pulley having its peripheral groove in alignment with a point on the first portion of the hub spaced away from the shoulder and the center of said entry hole, the spacing between the point and the center of entry hole corresponding generally to the diameter of the line, whereby the second wrapping of the line around the hub is laid down adjacent the first wrapping, and each subsequent wrapping is laid down adjacent the preceding wrapping.
