RELEASE LEVER FOR MAGNETIC SWEEPER WITH THREE-SIDED CHANNEL STRUCTURE
20180271347 · 2018-09-27 ·

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.

CONTINUOUS DISCHARGE MAGNETIC SWEEPER APPARATUS WITH HORIZONTAL AXIS ROTARY CLEAN OFF
20250000326 · 2025-01-02 ·

A continuous discharge magnetic sweeper apparatus with horizontal axis rotary clean off is disclosed. The magnetic sweeper apparatus consists of a handle, back wheels or front caster, a frontal debris bin and drive wheels housing a ceramic magnetic assembly. The ceramic magnetic assembly comprises a sealed magnetic drum and rotating non-ferrous finned tube, and the magnet is continuously cleaned off as the magnetic sweeper apparatus is pushed forward. Magnetic debris accumulates on the outside of the finned tube at the bottom of the sealed magnet assembly and is deposited in the frontal debris bin. The magnetic sweeper apparatus' horizontal axis continuous discharge design utilizes field differences created by the magnet position and angle to achieve the automatic pick-up and drop-off of debris at different locations of the drum.

A continuous discharge magnetic sweeper apparatus with a vertical axis rotary clean off attachment. The main magnetic sweeper consists of a handle, a back wheel, a frontal debris bin, a drive wheel and a finned drum housing a magnetic assembly. Magnetic debris is attracted by magnet assembly, accumulates on the finned drum and is deposited in the frontal debris bin. The vertical axis rotary clean off attachment connects to the magnetic sweeper and consists of a main frame body, a mounting feature, a support wheel, a rotary cap and a finned driving wheel. The finned driving wheel is a hollow finned wheel driven by contact with a wall, assisting the magnetic field to move shot from the wall side into the main sweeper's range to be picked up by the main sweeper apparatus.

Electromagnetic Nail Sweeper

The electromagnetic sweeper has many advantages over current magnetic sweepers. For example, one can turn off the electric current to release the ferrous material which has been captured by the sweeper. One does not have to pull off captured materials due to the use of electromagnets rather than permanent magnets. The device is also light weight and very easy to use.
