Abstract
Novelty Magnet Top A permanent magnetic top is arranged to rotate on one or more surfaces, of a toy induction turret, which are in close proximity to a coil. An electric circuit is arranged to switch the coil in such a manner so as to accelerate the top. A handle is connected to the turret so that the top maybe skillfully transferred from one surface to another. In one version it is arranged to generate a tone or musical notes when the top is spinning.
Description
Di~closure This invention relates to a magnetic toy and more particularily to an electric motor having a magnetic top as a rotor, in which the top can be manipulated in a skillfull fashion.
Andrew~ United States patent 3783550 describes a novelty electric motor compri~ing a magnetic top and an induction coil which i3 automatically energized from a battery. The spinnir!g of the top on a concaYe surface clo~e to the coil, induce~ voltage~ in the coil which cyclically turn~ on a transi~tor. Th8 transi~tor when switched on connect~ the battery to the coil producing a magnetic field whîch accelerate~ the top. The top spins on a ~oncave ~ur ace in clo~e proximity to the coil~
By attaching a handle to the combination of the coil, battery, ~ransistor and concave surface a ~urret i~ formed, on which the top can be ~killfully manipulatedO Also by placing several concave qurface~ in close proximity to the coil, the top maybe thrown from one surface to another, wherein it i~ accelerated on each urface, ~hereby keeping it spinning.
Two induction turret~ can be used to juggle two or more tops. A
sounder i~ used to produce a buzzing note or a mu~ical note when the top spin~ on a concave surface. In one arrangem*nt it acts a~ a musical instrument by producing a different note for aach . --~33~
Figure 1 shows an induction turret 1 having a head 2 and a multitude of concave su~faces 3. Inside turret 1 is an induction coil 4 having an iron core 6. Coil 4 iq located in close proximity to concave surfaces 3. Also located inside turret 1 are NPN
transistors 5 and 8, a 1 megohm current limiting resistor 7,.a piezo electric sounder 9 and a bat~ery 10. A handle 11 i5 attached to head 2.
Also shown is a top 12 comprising a disc magnet 13, with poles as shown,a spindle 14 and a pivot 15.
Transistor 5, coil 4 and top 12 form an electric motor powered by a battery 10, in which coil 4 is the stator and top 12 is the rotor. When top 12 is spun on anyone of the surfaces 3, which must be held horizontal, its rotating magnetic ~ield induces a voltage in coil 4, which turns on transistor 5. This alternately switches battery 10 across coil 4, producing a magnetic field which accelerates top 12. Push pull arrangements are possible, t'.ey would more efficently activate the coil.
By holding handle 11 the top 12 can be thrown from one concave surface 3 and caught on another concave surface 3. The magnetic field produced by coil 4 will power top 12 almost anywhere in a sphere in close proximity to coil 4; therefore a multitude of surfaces maybe located around coil 4. The top does not tend to be powered when its axis of rotation is directly in line with core 6.
Resistor 7, transistor 8 and sounder 9 produce a sound which emulates the speed of rotation of top 12. Transistor 8 switches on in synchronism with tran~istor 5, both of which are driven by coil 4. Sounder 9 produc-es a beep every time transistor 8 is switched on. This occurs at the rate of rotation of top 12.
Figure 2 shows a 47000 ohm current limiting re~i~tor 20 in series with a diode 21. Diode 21 i9 connected to a 1 megohm resistor 22, a 1 mfd capacitor 23 and an NPN tran~i~tor 24. Relay 25's coil is connected in aeries ~ith ~he collector of transi3tor 24. It~
con~act~ are connected to swi~ch on a device 26. Device 26 can be an electronic music generator, a light, logic circuitry to play games, etc.

Points A B and C of figure 2 are connected to points A B and C of figure l. Items 7, 8 and 9 of figure l are deleted.
When top 12 spins a voltage is generated in coil 4 which is rectified by diode 21 charging capacitor 23, turning on transi tor 24 which activates relay 25. Relay 25 turns on device 26.

A sensing coil 31 is placed close to each concave surface 3 of figure l. When top 12 rotates close to a coil 31 it induces an alternating voltage in it, which is amplified by transistor 33 and i~ rectified by rectifiers 36 and 37, charging capacitor 39.
This will turn on transistor 40 connec~ing resistor 41 to the ~
battery connection. This will cause transistor 43 to o~cillate at a frequency dependent upon the resistance of resistor 41 and the capacitance of capacitoe 42. Transistor 47 amplifiers this tone which is heard in transducer 48.
