  • Patent number: 7331470
    Abstract: A magnetic raking device that agitates a ground surface and uses magnetic attraction for collecting ferro-metallic debris, such as nails and screws, at construction jobsites and other locations, includes a release mechanism that temporarily eliminates magnetic attraction of the debris to the rake, thus allowing collected debris to drop from the rake, such as into a trash or recycling container. One type of release mechanism physically removes one or more magnets from the rake body to eliminate magnetic attraction to the rake body. One type of release mechanism uses electromagnets in the rake body that attract ferro-metallic debris when current is allowed to run through the electromagnets, and that allows the debris to drop from the rake when the current is interrupted. The magnetic rake may be used in an inverted position to attract ferro-metallic debris without agitating, and may be used in a non-magnetic state as a conventional rake.

  • Patent number: 5383696
    Abstract: A shovel is disclosed having a conventional shovel handle and yoke with the surface formed of flattened expanded metal. The flattened expanded metal is conventional and of the type that forms a grid of four sided diamond shaped openings having an elongate dimension and a short dimension. The flattened expanded metal is aligned parallel to the handle of the shovel and cut to a width and length sufficient to form the shovel body. The left and right edges as well as the top of the expanded metal are lined with straight bars to impart even and uninterrupted side edges and a foot hold top edge adjacent the yoke. The flattened metal forming the body of the shovel is given a conventional arcuate section and formed from metal having sufficient strength that all necessary support for the shovel surface is from the flattened metal. The front edges are cut to expose the elongate diamonds of the flattened expanded metal in a serrated configuration with at least the front serrated edge being hardened.
