Abstract: A magnetic tool for manipulated conveyance over a surface for magnetic collection of ferrous articles. This tool has a three-sided extruded channel, which cooperates with an opposing steel top plate to form a protective magnet housing for one or more magnets.The extruded channel is configured to direct magnet flux downward to optimize the attraction efficiency of the tool.Magnetic flux is further optimized by the use of multiple magnets in the channel housing of opposite polarity. The steel top plate channel also serves as the primary structural element of the tool for attachment of conveyance and manipulation means, such as an adjustable handle by means of an ACME collar and two axles for wheels.The invention is the three-sided extruded channel, that has an incorporated track for a free-floating hinged release lever. The release lever has been designed specifically as a means of easily removing ferrous material attracted by the three-sided channel, that allows to pass through the magnetic field from the magnets. As a means of incorporating minimal mechanical friction, the magnets are allowed to remain in a static position within the housing. A free-floating release lever is incorporated via a hinge into the extruded housing as to create a space gap between the magnetic field and the ferrous materials collected when operated. This allows for easy removal of the ferrous material without the operator having to be in direct contact with it.

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. The separation allows for the ferrous material to fall in the drop collection box by ways of gravitational pull.
