  • Patent number: 10856717
    Abstract: A free-floating, hinged release lever on an incorporated track to a three-sided extruded channel housing, which holds multiple magnets with opposite polarity. The housing has a steel top plate to allow for centering a female ACME connector for the attachment of a handle and to allow for an axle at each end to hold wheels for ease of conveyance. After the three-sided extruded channel housing—encapsulated by the free-floating, hinged release lever—has collected ferrous debris, the release lever is pushed away from the housing to allow for easy removal of ferrous material by it falling off by gravitational force without the operator having to be in contact with the metal debris. The magnets remain in place during the entire removal process.

  • Patent number: 10857654
    Abstract: A magnetic hand tool and method of assembly for manipulated conveyance over a surface for magnetic collection of ferrous articles, by which procedure a quick-release cap is used to release any and all collected ferrous material. This tool utilizes an alignment insert in a central opening of the magnet to coaxially align fastener guide holes through polar plates or protective covers on opposing planar sides of the magnet and a fastener guide hole in the insert, whereby insertion of the fastener through the guide holes laterally aligns the components of the assembly. The invention is the release device/cap, that is part of the assembly by means of a self-adhering or hinged cap with a lip, square, circular or other shape, to aid in the separation of ferrous material from the magnetic tool by pushing away the cap from the magnetic hand tool by holding the lip for that purpose. The divots make it that the release lever device/cap is held onto the magnetic hand tool assembly.
