  • Publication number: 20230354989
    Abstract: The double action cleaning tool of the present invention includes a dynamic double action dual brush head and a handle. The dynamic double action dual brush head includes two brush heads rotatably attached to a brush head base, allowing the brush heads to independently rotate about the axis in which it is rotatably attached to the brush head base. A mechanical device capable of storing and releasing energy is connected between the two brush heads, which is rigidly attached to the brush head base. The double action cleaning tool stores energy in the form of potential energy in the mechanical energy storage device of the dynamic double action dual brush head during the sweeping stroke of the double action push broom. At the end of the sweeping stroke, the stored potential energy is converted into kinetic energy and rotates the dual brush, thereby providing an additional sweeping motion.

  • Publication number: 20200338689
    Abstract: A guard attachment for a grinding tool has a metal body with an upper surface, a side wall along part of a perimeter of the upper surface, and a connector with which it can be attached to a grinding tool. Additional features include a bottom plate opposite the upper surface and a debris outlet attached at one end to the surface and side wall of the guard, and having a magnet removably attached to the other end. The bottom plate swivels outward from the body of the guard to facilitate changing the wheel or disk of the grinding tool. The magnet has an aperture allowing for the passage of air, but prevents sparks from escaping the guard attachment.
