Magnetic holders for cylindrical objects
First Claim
1. A holder for magnetic metal cylinders of regularly varying diameters which comprises:
- an elongated member having a plurality of closely spaced partial-cylindrical transverse recesses along a first surface;
said partial-cylindrical recesses increasing in diameter along at least a portion of said first surface, said recesses having an inner surface;
an elongated magnet in engagement with said elongated member opposite said recesses;
a surface of said magnet positioned adjacent to said recesses and having alternate transverse north and south pole regions with an interface between each pair of regions;
said interface between adjacent surface north and south pole regions lying substantially in a plane including the axis of each recess and perpendicular to said elongated member; and
a non-magnetized region having a thickness of from about 0.020 to 0.100 inch emplaced at said interface between each adjacent pair of north and south poles;
whereby a cylindrical object placed in a recess of corresponding diameter will be closely adjacent to said magnet along said interface between adjacent north and south poles.

Abstract
A holder for supporting magnetic cylindrical tools of varying diameter such as wrench sockets, drill bits, etc. in order. A member having a series of recesses having shapes corresponding to the tools to be held is backed by an elongated magnet. In one embodiment, the .member is a non-magnetic material and the magnet is made up of a plurality of transverse magnetic regions, having alternately north and south pole regions on the surface toward the recesses, with the lines between adjacent north and south regions aligned with the centerline of the recesses and a narrow non-magnetized region separating each pair of adjacent magnetic regions. In a second embodiment, the member is formed from a magnetic a U-shaped sheet with the recesses formed in opposed sidewalls. The magnet is held between the sidewalls below the recesses and has two longitudinally arranged north and south poses at the surface toward the recesses, with the pole line running longitudinally along the center of the magnet and a narrow non-magnetized region is interposed along the line between the magnetic regions. A third embodiment has a corrugated backing plate faced with the alternating magnetic regions. A fourth embodiment has a solid plastic holder with individual magnet assemblies inserted at the bottom of each of a series of recesses.
