Abstract
Abstract A toy for use by one or more players utilizing magnetic repulsion and attraction consisting of a casing, a pivotal member rotatably mounted on top of the casing having a plurality of apertures in its periphery into which are inserted one or more pivotal member rods each having a bar magnet rotatably mounted at its end. Extending from the casing below the pivotal member are one or more lower rods each having a bar magnet mounted at its end positioned in such a way that when the pivotal member revolves, the bar magnet on the pivotal member rod passes directly over the bar magnet mounted on the lower rod. When both the pivotal member bar magnet and the lower rod bar magnet have like poles in close proximity, magnetic repulsion will cause the pivotal member to revolve.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A magnetic toy comprising: a casing; a rotatable pivotal member on top of said casing having a plurality of apertures located on its outer circumference; a pivotal member rod, one end of which is inserted into one of said apertures; a pivotal member bar magnet rotationally mounted at the other end of said pivotal member rod; a neck section of said casing located below said pivotal member; a lower rod extending out from said neck section parallel to said pivotal member rod; a lower bar magnet mounted at the end of said lower rod positioned below said pivotal member bar magnet wherein said pivotal member bar magnet and said lower bar magnet are affected by each other's magnetic field; and means for rotating said lower rod.
Claim 2
Dependent Claim
126 words
A magnetic toy comprising: a casing; a rotatable pivotal member on top of said casing having a plurality of apertures located on its outer circumference; a pivotal member rod, one end of which is inserted into one of said apertures; a pivotal member bar magnet rotationally mounted at the other end of said pivotal member rod; a neck section of said casing located below said pivotal member; a lower rod extending out from said neck section parallel to said pivotal member rod; a lower bar magnet mounted at the end of said lower rod positioned below said pivotal member bar magnet wherein said pivotal member bar magnet and said lower bar magnet are affected by each other's magnetic field; and means for rotating said lower rod.
Claim 3
Dependent Claim
51 words
An apparatus as recited in claim 1 further including a plurality of said pivotal member rods, one end of each inserted into one of said plurality of apertures, and a plurality of said pivotal member bar magnets each rotatably mounted at the other end of each of said pivotal member rods.
Claim 4
Dependent Claim
23 words
An apparatus as recited in claim 1 further including a plurality of said lower rods, each having a lower bar magnet mounted thereon.
Claim 5
Dependent Claim
129 words
An apparatus as recited in claim 1 wherein said means for rotating each of said lower rods and said lower bar magnets comprise: a control knob located at the base of said casing; a first pulley; a control shaft connecting said control knob to the center of said first pulley; a second pulley; a belt connecting said first pulley to said second pulley; a casing shaft connected to the center of said second pulley; a first bevel gear located at the top end of said casing shaft; and a second bevel gear interconnectively associated at a right angle to said first bevel gear forming a right angle gear, said second bevel gear attached to said lower rod so that when said control knob is turned, said lower rod rotates.
Claim 6
Dependent Claim
69 words
An apparatus as recited in claim 1 further including: a toothed ratchet located on top of said neck section; a pawl rotatable affixed to the lower side of said pivotal member so that said pawl engages said ratchet in one of two positions causing unidirectional movement depending upon its position and further, when said pawl is disengaged from said ratchet, said pivotal member can revolve freely in either direction.
Claim 7
Dependent Claim
20 words
An apparatus as recited in claim 1 further including ball bearings located between said pivotal member and said neck section.
Claim 8
Dependent Claim
13 words
An apparatus as recited in claim 1 wherein said bar magnets are electromagnets.
Claim 9
Dependent Claim
51 words
An apparatus as recited in claim 3 wherein the positive poles of said pivotal member bar magnets and said lower bar magnets are of a distinct color and the negative poles of said pivotal member bar magnets and said lower bar magnets are of a different color than the positive poles.
