Spool For Straight Through Line Feed Vegetation Trimmer Apparatus With Modules And Spokes

A trimmer head of a vegetation trimmer machine, the trimmer head comprising:

• a housing having opposing eyelets sized to receive trimmer line therethrough;
• a spool rotatable within the housing around an axis of rotation, the spool comprising:
• a central core extending along the axis of rotation;
• an upper flange extending radially outwardly from the central core;
• a lower flange extending radially outwardly from the central core;
• a middle flange extending radially outwardly from the central core, the middle flange substantially parallel to the upper and lower flanges;
• a first chamber defined along the core between the upper flange and the middle flange and configured to store trimmer line;
• a second chamber defined along the core between the middle flange and the lower flange and configured to store trimmer line;
• and
• a trimmer line guide channel coplaner with and passing through the middle flange, wherein said guide channel comprises a first flange passageway extending from the central core to a first side of the spool and a second flange passageway extending from the central core to a second side of the spool opposing the first side, each of the first and second flange passageways having corresponding first and second openings alignable with corresponding eyelets in the housing;
• a removeable module installable within the central core, wherein said module includes a passage connecting the first and second flange passageways, and sized for receiving said trimmer line therethrough;
• wherein the trimmer line guide channel has a first opening and a second opening alignable with respective eyelet openings the trimmer head.

A spool for a trimmer head of a vegetation trimmer machine comprising:

• a central core extending along an axis of rotation;
• an upper flange extending radially outwardly from the central core;
• a lower flange extending radially outwardly from the central core;
• a chamber defined along the core between the upper flange and the lower flange and configured to store trimmer line;
• a substantially straight trimmer line guide channel coplanar with and passing through the upper flange or the lower flange and passing though the axis of rotation, wherein said guide channel comprises a first flange passageway extending from the central core to a first side of the spool and a second flange passageway extending from the central core to a second side of the spool opposing the first side, each of the first and second flange passageways having corresponding first and second openings alignable with corresponding eyelets in the housing;
