Abstract
Abstract A disc supporting a first magnet at its periphery is caused to revolve by magnetic induction due to movement of a second magnet adjacent but spaced from the periphery of the disc. The second magnet is mounted for reciprocal movement in a direction generally parallel to the axis of rotation of said disc.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
76 words
Apparatus comprising support structure, a disc having a magnet along substantially one of the peripheral surfaces of the disc, means on said structure supporting the disc for rotation about its axis, and means for supporting a second magnet adjacent to but spaced from said peripheral surface of the disc in a manner so that the second magnet is movable in a direction generally parallel to said axis to induce the disc to rotate about said axis.
Claim 2
Dependent Claim
76 words
Apparatus comprising support structure, a disc having a magnet along substantially one of the peripheral surfaces of the disc, means on said structure supporting the disc for rotation about its axis, and means for supporting a second magnet adjacent to but spaced from said peripheral surface of the disc in a manner so that the second magnet is movable in a direction generally parallel to said axis to induce the disc to rotate about said axis.
Claim 3
Dependent Claim
33 words
Apparatus in accordance with claim 1 wherein said last mentioned means supports the second magnet for reciprocation to a position slightly above and to a position slightly below the plane of the disc.
Claim 4
Dependent Claim
37 words
Apparatus in accordance with claim 1 wherein said last mentioned means supports the second magnet for oscillation from a position slightly above the plane of the disc to a position slightly below the plane of the disc.
Claim 5
Dependent Claim
26 words
Apparatus in accordance with claim 1 wherein said last mentioned means includes a flexible arm having said second magnet supported at one end of the arm.
Claim 6
Dependent Claim
24 words
Apparatus in accordance with claim 1 wherein said disc is provided with a notch or recess in which said first mentioned magnet is received.
Claim 7
Dependent Claim
21 words
Apparatus in accordance with claim 1 including indicia on said disc designating the poles of the magnet supported by the disc.
Claim 8
Dependent Claim
19 words
Apparatus in accordance with claim 1 wherein said support structure and disc are made from a polymeric plastic material.
Claim 9
Dependent Claim
122 words
An amusement device comprising a horizontally disposable support structure, an upright pin on said support structure, a round disc having a hole in its center, said pin extending through said hole and supporting said disc for rotation about the axis of said pin, a first magnet secured to substantially the entire length of the outer periphery of said disc, a second magnet movably supported, means for supporting and moving said second magnet adjacent to but spaced from the periphery of said disc in a manner so that the second magnet is moved generally parallel to the axis of said pin from a position slightly above the plane of the first magnet to a position slightly below the plane of the first magnet.
Claim 10
Dependent Claim
122 words
An amusement device comprising a horizontally disposable support structure, an upright pin on said support structure, a round disc having a hole in its center, said pin extending through said hole and supporting said disc for rotation about the axis of said pin, a first magnet secured to substantially the entire length of the outer periphery of said disc, a second magnet movably supported, means for supporting and moving said second magnet adjacent to but spaced from the periphery of said disc in a manner so that the second magnet is moved generally parallel to the axis of said pin from a position slightly above the plane of the first magnet to a position slightly below the plane of the first magnet.
Claim 11
Dependent Claim
27 words
An amusement device in accordance with claim 8 when said second magnet is mounted on a carrier supported for reciprocation parallel to the axis of said pin.
Claim 12
Dependent Claim
27 words
An amusement device in accordance with claim 8 wherein said second magnet is mounted on a carrier which oscillates with respect to the axis of said pin.
