Abstract

An electric torch includes an illumination source 9, a switch 8 and means for generating electricity using the repulsive force of permanent magnets. Four bar magnets 2 are repulsed and rotated by a cylindrical surrounding magnet 3 generating an electrical current in coils 6.

Description

Perpetual Torch Description

Perpetual Torch is self powered by mgne,_sm.

Fig 1 is an internal Ales of the Perpetual Torch.

Fig 1.1 is the cylindrical magnet plunger, when this is screwed down into the position shown then the light.

will work if it is switched on, there is an overlap at the end of the main body of the light so that the plunger cannot be completely screwed out of the Perpetual Torch main body. Fig 1.2 is bar magnet which is attached to the bearing race inner ring of bearing race Fig 1.4.

Fig 1.3 is the cylindrical magnet. Fig 1.5 is protrusion from a cylinder of iron, around which the copper coil Fig 1.6 is Wound. Fig 1.7 is the end of the cylinder of iron which protrudes so that the copper coil does not compress and correct orientation of the components is facilitated when the light hood Fig 1.11 which is of clear plastic is screwed down. Fig 1.8 is the on off switch of the device. Fig 1.9 is the light bulb. Fig 1.10 is the light reflector.

Fig 2 is a side on view of the device with the cylindrical magnet plunger screwed out so that the device cannot generate energy and thus even when the switch as shown is in the on position the light will not work.

Fig 3 is the light hood of the Perpetual Torch into which the reflector goes.

Fig 4 is the reflector of the Perpetual Torch.

Fig 5 is the light bulb holder of the Perpetual Torch. Fig 5.1 is a channel in the light holder to position the light holder correctly in the Perpetual Torch, the light holder thereby slides into protrusions that jut out from the inside the main body of the Perpetual Torch to locate it and make electrical connections. Fig 5.2 is a power connector, which makes contact with the end of the light bull's end connector.

Fig 5.3 is the light bulb. Fig 5.4 is a power connector, which makes contact with the side of the light bulb. The power connectors from the light bulb holder connect up to electrical connectors that are arranged on the inner surface of the main body of the Perpetual Torch via sprung copper connector strips which are in turn connected up to the switch. There are electrical connections on the inner surface of the main body of the Perpetual Torch which connect up to the copper coil of the electrical power generator, the connection points are of sprung copper strips.

Fig 6 is the energy generator of the perpetual Torch;' Fig 6.1 is a copper coil, the copper coil is of copper wire which has an insulative coating surrounding it.

Fig 6.2 is the protrusion of the cylinder of iron about which the copper coil is wound, there are eight such protrusions of the iron cylinder around the circumference of the cylinder of iron. Fig 6.3 is a cylindrical magnet which has magnetism emitting from its outer surface area. Fig 6.4 is a hole in the cylindrical magnet to which the cylindrical magnet is connected to the inner ring of the bearing race. Fig 6.5 is the cylinder of iron. The connectors of the generator which are of sprung copper strips make contact with the sprung copper strip connectors which are also arranged on the inner surface of the main body of the Perpetual Torch.

The power generator is correctly positioned due to recesses around the circumference of the generator, such that the generator slides into protrusions of the inner surface of the main body of the Perpetual Torch.

Fig 7 shows the means of turning the permanent magnet of the energy generator. Fig 7.1 is a bearing of the bearing race. Fig 7.2 shows the cylindrical magnet which surrounds the bar magnets. Fig 7.3 shows an end view of one of the four bar magnets which are connected to the inner ring of the bearing race so that they can rotate. Each of the bar magnets rotate due to it magnetism opposing the magnetism which is centripetal of the magnetism of the cylindrical permanent magnet. the cylindrical magnet is a south pole on its inner surface.

The bar magnets each have a south pole face which faces the inner surface of the cylindrical magnet r there plane being at an angle so that magnetic repulsion takes place and they thus rotate.

Claims

Perpetual Torch Claims 1. The Perpetual Torch is powered by magnetic

repulsion and has four bar magnets that are attached to bearing race so that they can rotate, a cylindrical magnet is pushed around these bar magnets by a plunger which is screwed down, getting power and thus light from the device is dependent on the amount the cylindrical magnet surrounds the bar magnets and on the position of a switch, the device can be switched on or turned off, the bar magnets do not directly facing the inner surface of the cylindrical magnet (the bar magnets are so orientated that a perpendicular from the line along the centre of each bar magnet is at an angle to the line that passes through the centre line of each bar magnet from the inner surface of the cylindrical magnet to the centre line of each magnet for each bar magnet) a force is created due to magnetic fields of force being cut and the angle of the bar magnets inside the cylindrical magnet causes a resultant moment which thus rotates the bar magnets and hence the axle of the device which then due to an arrangement of cogs rotates via a bearing race a permanent magnet cylinder of a generator which supplies a copper coil with energy which then via a switch can turn on a light bulb, the device is substantially as described herein with reference to the accompanying description and drawings.
