Total Claims: 17
Claim 1
Independent Claim
84 words
A blower attachment for use with a filament line trimmer which has a shaft and means for rotatably driving the shaft, the shaft further having means thereon for normally securing a filament line spool thereto, comprising: at least a pair of blades for detachably mounting around said spool for rotation therewith, said blades being extendable laterally therefrom, said blades when extended and upon rotation of said spool blowing air and the grass clippings and debris cut by said trimmer away from the trimmed area.
Claim 2
Dependent Claim
84 words
A blower attachment for use with a filament line trimmer which has a shaft and means for rotatably driving the shaft, the shaft further having means thereon for normally securing a filament line spool thereto, comprising: at least a pair of blades for detachably mounting around said spool for rotation therewith, said blades being extendable laterally therefrom, said blades when extended and upon rotation of said spool blowing air and the grass clippings and debris cut by said trimmer away from the trimmed area.
Claim 3
Dependent Claim
85 words
A blower attachment for use with a filament line trimmer which has a shaft and means for rotatably driving the shaft, the shaft further having means thereon for normally securing a filament line spool thereto, comprising: a band for fitting around said spool for rotation herewith, said band selectively extending at least a pair of blades laterally therefrom, said blades when extended and upon rotation of said band blowing air and the grass clippings and debris cut by said trimmer away from the trimmed area.
Claim 4
Dependent Claim
85 words
A blower attachment for use with a filament line trimmer which has a shaft and means for rotatably driving the shaft, the shaft further having means thereon for normally securing a filament line spool thereto, comprising: a band for fitting around said spool for rotation herewith, said band selectively extending at least a pair of blades laterally therefrom, said blades when extended and upon rotation of said band blowing air and the grass clippings and debris cut by said trimmer away from the trimmed area.
Claim 5
Dependent Claim
17 words
