Abstract

A head for a string trimmer machine includes a housing member having a central axis. The housing member is adapted for attachment to a string trimmer machine and includes a serpentine guide path in the housing for a length of trimmer line, with the guide path being located in a plane including the central axis of the housing and terminating in exit openings on opposite sides of the housing.

Claims

exact text as granted — not AI-modified
1 . A head for string trimmer machines including: a housing member having a central axis for attachment to a string trimmer machine; and a serpentine guide path in the housing member for receiving a length of trimmer line, the guide path entirely located in a single first plane including the central axis and terminating in exit openings on opposite sides of the housing member.  
   
   
       2 . A head according to  claim 1  wherein the exit openings further are located in a second plane perpendicular to the plane including the central axis, and wherein the guide path has a portion thereof in the first plane located above or below the second plane.  
   
   
       3 . A head according to  claim 2  wherein the exit openings are located on diametrically opposite sides of the housing member.  
   
   
       4 . A head according to  claim 3  wherein at least the portion of the exit openings in contact with a trimmer line when pulled outwardly from the exit openings is metal.  
   
   
       5 . A head according to  claim 4  wherein the housing member includes an upper housing portion and a lower housing portion with the guide path formed by cooperating parts of the upper and lower housing portions.  
   
   
       6 . A head according to  claim 5  wherein the upper and lower housing portions are releasably interconnected with one another.  
   
   
       7 . (canceled)  
   
   
       8 . (canceled)  
   
   
       9 . (canceled)  
   
   
       10 . (canceled)  
   
   
       11 . A head according to  claim 1  including a second serpentine guide path in the housing member entirely located in a single second plane including the central axis, the second guide path terminating in a second set of exit openings on opposite sides of the housing member.  
   
   
       12 . (canceled)  
   
   
       13 . (canceled)  
   
   
       14 . (canceled)  
   
   
       15 . (canceled)  
   
   
       16 . (canceled)  
   
   
       17 . A head according to  claim 1  wherein at least the portion of the exit openings in contact with a trimmer line when pulled outwardly from the exit openings is metal.  
   
   
       18 . A head according to  claim 17  wherein the exit openings are located on diametrically opposite sides of the housing member.  
   
   
       19 . A head for string trimmer machines including: 
 an upper housing portion having a central axis for attachment to the drive shaft of a string trimmer machine;    a lower housing portion for releasable interconnection with the upper housing portion, and having a central axis aligned with the central axis of the upper housing portion; and    cooperating channels on the upper housing portion and the lower housing portion forming a non-linear serpentine guide path for a length of trimmer line, the guide path entirely located in a single first plane including the central axes of the upper and lower housing portions and terminating in exit openings on opposite sides thereof.    
   
   
       20 . A head according to  claim 19  wherein the exit openings are located in a second plane perpendicular to the plane including the central axes, and wherein the guide path has a portion thereof located above or below the second plane.  
   
   
       21 . A head according to  claim 20  wherein at least the portion of the exit openings in contact with a trimmer line when pulled outwardly from the exit openings is metal.  
   
   
       22 . A head according to  claim 19  wherein at least the portion of the exit openings in contact with a trimmer line when pulled outwardly from the exit openings is metal.  
   
   
       23 . A head according to  claim 22  wherein the guide path has, at least in part, a cross-sectional configuration conforming to the cross-sectional configuration of a string trimmer line to be guided therein.  
   
   
       24 . (canceled)  
   
   
       25 . (canceled)  
   
   
       26 . A head according to  claim 19  wherein the guide path has, at least in part, a cross-sectional configuration conforming to the cross-sectional configuration of a string trimmer line to be guided therein.  
   
   
       27 . A head according to  claim 26  wherein at least the portion of the exit openings in contact with a trimmer line when pulled outwardly from the exit openings is metal.  
   
   
       28 . A head for string trimmer machines including: a housing member having a central axis and adapted for attachment to the drive shaft of a string trimmer machine; and means in the housing member for guiding a length of string trimmer line in a serpentine path entirely located in a single plane including the central axis, the path terminating in exit openings on opposite sides of the housing member.  
   
   
       29 . (canceled)  
   
   
       30 . (canceled)  
   
   
       31 . The head according to  claim 28  wherein the cross-sectional configuration of at least a portion of the guide path is a rectangular cross section.
