Abstract: A trimmer head for use with either clockwise or counterclockwise trimmer heads, including the use of a bidirectionally dispensing spool. Various locations of passages straight through the trimmer head and spool are shown along with various locations of components of the ratcheting mechanism to allow for winding of the trimmer line on the trimmer head and for limiting the amount of line dispensed during “bumping” of the trimmer head knob on the ground. Additionally, an extended funnel into the passage can be provided to facilitate entrance of trimmer line into the funnel even when the line is not perfectly straight. Also, spokes can be used in place of the flanges of the spool to save material and cost, while still providing a guide and barrier between the line store areas.

Abstract: A trimmer head assembly for a trimming machine. The trimmer head assembly includes a spool. The spool has a central tubular hub. The spool also has a central flange that radially extends from the hub. A trim line conduit is joined to the central flange. The trim line conduit has a first open end. The first open end leads to a first straight section. The first straight section leads to a curved central section. The curved central section leads to a second straight section. The second straight section leads to a second open end. The curved central section passes around the center of the spool. A housing is provided that receives the spool therein. When loading trimmer line into the trimmer head assembly, the shaped of the conduit enables the trimmer line to pass around the central opening in the spool without binding.

Abstract: A trimmer head spool for a vegetation trimmer machine. The spool includes a hub that defines a bore and has at least one flange or a plurality of spokes extending radially outwardly therefrom. A trimmer line conduit defined in the spool includes a first funnel defined in a first region of the flange or spokes and a second funnel defined in a second region of the flange or spokes. A non-radial guide channel is in fluid communication with the first and second funnels. The non-radial guide channel spans the hub's bore and does not extend through a central axis of the spool about which the spool is rotatable. The non-radial guide channel may be provided on a module that is selectively inserted into the bore and aligned with the first and second funnels. In other embodiments the entire trimmer line conduit is integrally formed in the spool.

Abstract: A trimmer head for use with either clockwise or counterclockwise trimmer heads, including the use of a bidirectionally dispensing spool. Various locations of passages straight through the trimmer head and spool are shown along with various locations of components of the ratcheting mechanism to allow for winding of the trimmer line on the trimmer head and for limiting the amount of line dispensed during “bumping” of the trimmer head knob on the ground. Because of the careful arrangement of the components, the trimmer head can have line wound in a single direction on the spool and still dispense line regardless of the direction that the trimmer head rotates by speeding up or slowing down the spool relative to the trimmer head housing to allow line to dispense independent of the direction of the rotation of the trimmer machine drive shaft rotating the trimmer head.
