Abstract
A portable, hand held tool for trimming and electrifying vegetation. The portable, hand swingable, weed trimmer passes electricity through its cutting or trimming element so as to pass electricity into the weeds to kill the roots of the weeds. The tool includes a power unit for rotation of a cutter drive. A pancake generator generates electricity via rotation of the cutter drive. Brushes between the pancake generator and the cutter blade conduct current to the cutter blade, which in turn permits the current to pass into the vegetation as the cutter blade trims the vegetation.
Claims15
A portable hand tool for simultaneously trimming and electrifying vegetation, comprising, in combination:
- a) an elongate shaft with a proximal end portion and a distal end portion;
- b) a handle on the proximal end portion for swinging the trimmer back and forth;
- c) a vegetation trimmer unit on the distal end portion, with the trimmer unit comprising a rotating cutter for cutting vegetation, with the rotating cutter comprising a material which is conductive of electricity, and with the tool delivering electricity to the rotating cutter which in turn transfers such electricity to the vegetation.
A portable hand tool for simultaneously trimming and electrifying vegetation, comprising, in combination:
- a) an elongate shaft with a proximal end portion and a distal end portion;
- b) a handle on the proximal end portion for swinging the trimmer back and forth;
- c) a power unit on the tool;
- d) a drive being rotated by the power unit;
- e) an electrical generator on the tool;
- f) a vegetation trimmer unit on the distal end portion, with the trimmer unit comprising a rotating cutter for cutting vegetation, with the rotating cutter being driven by the drive, with the rotating cutter comprising a material which is conductive of electricity and being electrically connected to the electrical generator;
- and
- g) wherein the electrical generator generates electricity in response to the drive being rotated by the power unit which in turn transfers such current to the rotating cutter which yet in turn transfers such current to the vegetation.
An improved portable hand tool for trimming vegetation, comprising, in combination:
- a shaft with a proximal end portion and a distal end portion;
- a handle on the proximal end portion for swinging the trimmer back and forth;
- a drive on the shaft;
- a rotating cutter on the distal end portion for cutting vegetation, with the rotating cutter being driven by rotation of the drive;
- wherein the improvement comprises, in combination:
- a) a generator on the drive and generating electricity in response to rotation of the drive;
- b) a contact between the generator and the rotating cutter to deliver electricity from the generator to the rotating cutter;
- and
- c) with the rotating cutter comprising a material which is conductive of electricity such that the rotating cutter carries such electricity to the vegetation being cut.
