  • Patent number: 5239811
    Abstract: Secondary cutting blades are mounted on a line trimmer between the hub carrying the cutting line and the shield. The cutting blades extend parallel to the axis of rotation of the hub carrying the cutting line. The blades have one end adjacent to the periphery of the hub, and the other end supported at or above the shield. Tall grass or other long stalks will therefore be cut by the blades and unable to wrap around the trimmer.

  • Patent number: 5212346
    Abstract: An electrical junction box is generally cylindrical, and has terminals on the peripheral surface. The box is divided into a plurality of layers, each layer being one polarity, so polarized wires can be easily plugged into the appropriate terminals. A cover may be used over the box if desired, the cover being fixable to the box. Also, the cables to be connected in the box may be fixed with respect to the box. Each terminal has a release slot adjacent to it so wires can be removed as desired. Each layer has a connector that electrically connects all terminals in that layer.
