Abstract
Abstract An improved magnetic pick-up device and marker for use in games includes a rectangular ferromagnetic member having a length substantially greater than width. The ferromagnetic member is fixedly received in a rectangular socket affixed to an elongated handle. The handle with the ferromagnetic member affixed thereto may then be used to retrieve a circular marker formed of translucent material and having ferromagnetic properties after the marker has been utilized as an indicator in a game.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
114 words
A magnetic pick-up device and a marker comprising: an elongated handle; a ferromagnetic member having a rectangular cross section and a length substantially greater than its width; a rectangular socket affixed to said handle for fixedly receiving internally said ferromagnetic member; circular marker means for use with a game; said circular marker means comprising a translucent disc and a metallic screen, said screen having ferromagnetic properties, said translucent disc defining first and second substantially parallel surfaces, said screen embedded in said translucent disc between said first and second substantially parallel surfaces; whereby said marker means is attracted towards said ferromagnetic member when said ferromagnetic member is passed in the vicinity of said marker means.
Claim 2
Dependent Claim
114 words
A magnetic pick-up device and a marker comprising: an elongated handle; a ferromagnetic member having a rectangular cross section and a length substantially greater than its width; a rectangular socket affixed to said handle for fixedly receiving internally said ferromagnetic member; circular marker means for use with a game; said circular marker means comprising a translucent disc and a metallic screen, said screen having ferromagnetic properties, said translucent disc defining first and second substantially parallel surfaces, said screen embedded in said translucent disc between said first and second substantially parallel surfaces; whereby said marker means is attracted towards said ferromagnetic member when said ferromagnetic member is passed in the vicinity of said marker means.
