THE POWER OF THE SWING - A NEW TECHNIQUE OF GENERATING ELECTRICITY.

The invention is a new method of electricity generation or work done to drive electrical loads or mechanical loads respectively by tapping the bi-directional or uni-directional motion of the swing.

PROBLEM ATTEMPTING TO SOLVE:

A major part of world today still doesn't have basic lighting facilities or motive power available to draw water \ or run any devices. Energy is getting costlier by the day and power cuts today are becoming a crude reality even for people living in cities across the globe. A huge chunk of population living in the so-called rural areas of the world, due to huge transmission costs will not get electricity in the near future. Fossil fuels are being burnt for basic lighting in these areas, which create air pollution, and adding to the already polluted environment. People have been putting a lot of effort to manually do a lot of work (e.g. to draw water manually or to run flour mills), which could be accomplished easily by using electrically driven devices. This is the current scenario. We propose a new method to solve the above-mentioned problems for basic lighting and give the required motive power to drive mechanical loads such as manual water pumps or other agriculture devices or any machines, which could be run, by the generated motive power by the proposed new method and device. Our proposed devices made by the new method do not involve any use of fossil fuel and is simple in construction and the materials used are also simple and readily available. Hence the construction and use is very simple and anyone can use it. The invention can be very useful in providing a simple method to drive electrical loads or mechanical loads in space ships for people going on space missions for whom the available power is very limited which puts a lot of constraint on these people in their quest to explore and study the outer space which would further help humans understand the universe in a better light.

PRIOR ART OR ARRANGEMENT:

There is no precedence to this innovation though the primary object, which is the swing, has existed since a very long time, and has been used as a recreational tool in all societies of the world.

ADVANTAGES:

. All components can be locally produced, easily maintained.

. No specialized materials, skill sets are required.

. Ready to use when assembled.

. No emissions or consumption of any fossil fuel or dependence on any natural resources like wind, sun, waves etc.

. By using the device, person or persons using it will burn calories while producing electπdty or drive mechanical ^ads.

. Weight of the person and height of the swing are directly proportional to the quantum of energy produced.

. A large spectrum of age groups can use the device i.e. from children to old persons who otherwise cannot do hard work, but be useful to drive mechanical loads such as to draw water or generate electricity and thereby play an important role in the entire system in which they would be of little use otherwise.

. It can replace lantern which use fossil fuels to provide lighting in small rooms, or on tables as reading lamps etc to help us reduce pollution by its use and to make lighting available also during power cuts. It also will lessen the burden on the major power grids supplying majority of power to most of the world today and help its user to save money by reducing electric bills

. Small versions of the devices can be produced if the requirement is small.

. The devices could help a whole spectrum of pollution of common men and farmers who can increase the productivity of the available land as more water could be at their disposal by its use, helping them draw water or use many agriculture equipments and many devices which required motive power thereby opening many avenues to start small scale industries etc.

. Due to the use of the devices, a large percentage of global population would be able to be exposed to TV or radios or info media, etc, educating them about current scenario's in various subjects and helping them to be more informed about the current world situation and latest developments in all fields, who could not till date were not exposed to them.

LIMITATIONS.

. In places where there is space constraint. In that case we would have to reduce the size of the device, which would reduce the output proportionately.

. To induce motion to the swing, there is dependency on a human being or animal, which could keep the swing moving.

. Given the constants of weight of the person to the height of the swing to the total duration of the movement of the swing, the energy, which gets delivered or produced, is constant.

DESCRTPTTON

The following describes the construction of the conventional swing.

Vertical stands 14 and 15 are fixed on ground by the square flanges a, b, c, d, and e, f, g, h, respectively fixed to the ground with foundation bolts. Two pedestal bearings 1, 2 are mounted on the top of the stand 14, 15 respectively. Centre shaft 3 is held on either Sides by fhe two pcv'esta! be^ ^' .ngs t . 2. ^τ \vo identical round flanges 6, 7 are fitted on the centre shaft 3 between the u /υ pedestal bearings 1 , 2 and equi-distant from them. Two identical pipes 4, 5 made of metal, wood or any suitable material are fitted on round flanges 6, 7 by one end, the other end of pipe 4, 5 is fitted on seat 8.The seat 8 is a rectangular seat which can be made of wood, metal, plastic, rubber or any other suitable material and size is enough for approximately 3 people to comfortably sit on it, but this seat can vary in size and material depending on requirement and availability. This is the construction of our conventional swing (SHEET 2 / FIG 2).

The conventional swing described here can be mounted on ceiling directly Instead of stands 14, 15. In the case where the conventional swing is mounted on the ceiling, the pedestal bearing 1,2 would have to be further mounted on a blocks bl, b2 which are made of metal or wood, and the blocks bl , b2 would be subsequently fixed on the ceiling (SHEET 1 / FIG 1). [The attachments which are necessary to make different devices can be modified to be fitted on the ceiling in the case where the swing is fitted on the ceiling directly]. The seat 8 is fixed with the metal pipes 4, 5, which are in turn fixed with flanges 6, 7 that are further mounted directly on centre shaft 3. The centre shaft 3 is mounted on either side by bearings 1, 2. When the swing is set in motion, due to the method of construction described above where the swing is mounted directly on the centre shaft 3, and when the swing is set in motion it will impart proportional rotation and power to the centre shaft 3. Henceforth we will call this centre shaft 3 as the prime mover 'A'.

The above construction remains the same for all the devices explained. Hence for simplicity, we would only mention the different types of additional construction for different devices in detail, which are an extension to the swing and the prime mover 'A'.

CONSTRUCTTON OF DIFFERENT TYPES OF DEVICES ARE AS FOLLOWS

1. THE DEVICES ARE BROADLY DIVIDED IN TO TWO CATAGORIES, THEY ARE

AS FOLLOWS:

CATEGORY ONE: HARNESSING THE BI-DIRECTIONAL MOTION OF THE SWING.

CATEGORY TWO: ONLY HARESSING ANY ONE DIRECTION OF MOTION OF THE

SWING.

CATEGORY ONE

The different types of devices that harness the bi-directional motion of the swing, and are an extension of the conventional swing, coupled to the conventional swing at its centre shaft 3 ( PRIME MOVER 'A') are described here as follows

TYPE.A> Construct the conventional swing with the prime mover 'A' as previously described. This is a common part of the construction for DEVICE 1.

E.G. The manual water pump (MECHANISM.1 and MECHANISM.2), The treadle water pump, their construction and working described as follows:

THE MANUAL WATER PUMP:

MECHANISM.l : Connect the device B.1 to the upper end of the piston of the manual water pump directly (SHEET 10, 11)

MECHANISM.2: the device B.I is connected to the lever handle's end of the manual water pump (SHEET 12) with the help of pulley which is fixed on the shaft 16.

DEVICE 3

MECHANISM.l: Gear 9b will be mounted on shaft 16 which in turn is supported on either sides by pedestal bearings 17a, 17b which are in turn mounted on plate 18a The pulley Al which is fixed on shaft 16 will be connected to a link A3(SHEET 10). This link A3 has a bearing A2 fixed at its extreme end, bearing A2 is further mounted by it's centre on the rod R, this rod R is fixed on the circumference of pulley Al. The other end of the link has a

bearing 2a fixed on it; bearing 2a is mounted on the pivot joint A4 by its centre. The pivot joint A4 is further mounted on the upper extreme end A7 of piston A5. When the swing imparts motion to the shaft 16, the pulley Al also is given oscillatory motion, which further translates it in a final up and down motion of the piston A5 with the help of the link A3 (SHEET 11) and thus will result in drawing water.

DEVICE 4

MECHANISMS: Gear 9b will be mounted on shaft 16 which in turn is supported on either side by pedestal bearings 17a, 17b which are in turn mounted on plate 18a. The pulley Al which is fixed on shaft 16 will be connected to a link A3. This link A3 has a bearing A2 fixed at its extreme end; the bearing A2 is further mounted by its centre on the rod R, this rod R is fixed on the circumference of pulley Al. The other end of the link A3 has a bearing 2a fixed on it and the bearing 2a is further mounted on the pivot joint A4 by its centre. The pivot joint A4 is further mounted on the extreme end of the lever handle A8, the other extremity of the lever handle A8 has a bearing 2b fixed on it and bearing 2b is further mounted on the pivot joint 4a by its centre. This pivot joint is fixed to the upper extreme end A7 of the piston A5. The lever handle A8 has a bearing 2c, which is fixed on it, and bearing 2c is mounted on pin P by its centre. This pin P is fixed on the fixed pivot A6. When the swing imparts motion to the shaft 16, the pulley Al also is given oscillatory motion which further translates it in an final up and down motion of the piston with the help of the link A3 which further imparts up and down motion to the lever handle A8, the other extremity of the lever handle A8 is further attached to the upper end of the piston A5 at its extreme end A7 by a pivot joint and bearing and also attached to a fixed pivot A6 with the help of a bearing, thereby giving the required up-down motion to the piston A5 to draw water(SHEET 12).

DEVICE 5

THE TREADLE WATER PUMP: Gear 9b will be mounted on shaft 16 which in turn is supported on either side by pedestal bearings 17a, 17b which are in turn mounted on plate 18a. The pulley Al which is fixed on shaft 16 will be connected to two identical links 3A and 3B at it's diametrically opposite ends near its circumference (SHEET 13). These links have a bearing 2A and 2B fixed at their extreme ends respectively, these bearings 2A and 2B are further mounted by it's centre on the two rods Rl and R2 respectively, both these rods Rl, R2 are mounted on the circumference of the pulley at diametrically opposite points. Bearing 3a and 3b are fixed on the other end of these two links 3A and 3B respectively and these bearings 3a and 3b are further mounted on the pivot joint PA and PB by their respective centres. Pivot joint PA and PB are fixed on one extremity of the treadle Tl and T2 respectively. These two treadles Tl, T2 are fitted with bearings 2AA and 2BB on the other extremity respectively; the bearings 2AA and 2BB are mounted on a common pin

P by their respective centres, this common pin P is fitted to the fixed pivot A6. The fixed pivot A6 is mounted on the stand A9, which is in turn fixed on the ground. The piston 5A and 5B have pin Pl and pin P2 fixed at its upper extremity 7A and 7B respectively. These pins Pl and P2 are further locked with the treadle Tl and T2 respectively by its open end passing thru the hole El and E2. The diameter of the holes El and E2 is slightly greater than the diameter of the pin Pl and P2, so as to give some free movement to the pin Pl and pin P2 in these holes El and E2. This results in the final hinder free movement of the piston 5 A and 5B when the treadle Tl and treadle T2 impart motion to them. When the swing imparts motion to the shaft 16, the pulley Al also is given oscillatory motion which further translates it in an final up and down motion of the piston 5 A and 5B w<th the help of the two links 3 A $nd 3B v.Sich imparts up and down motion to both the treadles Tl and T2, thereby givύig the req .-iced up-down motion to the iwo pistons 5A and 5B with the help of the pin Pl and pin P2 which are locked with the treadle Tl and T2 respectively as described above, thus resulting in drawing water (Sheet 13,14,15,16).

Output of generator 10 is connected to a rechargeable battery 11 via a full wave bridge rectifier circuit 10a. The rechargeable battery 11 is further connected to an inverter 12. When the prime mover 'A' rotates due to the motion of the swing, it imparts motion to the input of S.G.S 'a', the output of S.G.S 'b' imparts motion to the axle of the generator 10. Hence electricity is produced; this charges a rechargeable battery 11 via full wave bridge rectifier circuit 10a.

CATEGORY TWO

The different types of devices that only harness any one direction of motion of the swing, and are an extension of the conventional swing, coupled to the conventional swing at its centre shaft 3 (PRIME MOVER 'A') are described here as follows

TYPE.A.> Construct the conventional swing with the prime mover 'A' as previously described. Gear 9A has a uni-directional bearing fitted at its centre. Gear 9A is mounted on the prime mυvei 'A with the « ^* n-cirectional bearing at its centre, due to which only one direction of motion of the prime mover 'A' will be transmitted to the Gear9A and not during the rotation of the prime mover in the opposite direction, THE prime mover 'A' will rotate freely during the rotation in the opposite direction. This gear 9A is coupled with gear 9b. This is a common part of the construction for DEVICE 11, 12.

DEVICE 11

A.1> Gear 9b will be mounted on shaft 16, which in turn is supported on either side by pedestal bearings 17a, 17b that are in turn mounted on plate 18a. Shaft 16 is used to drive any mechanical load. In this case shaft 16 will rotate only in the clockwise or anti-clockwise direction as the prime mover 'A' transmits rotation of only one direction to gear 9A, which in turn rotates gear 9b in one direction and thus the shaft 16 also rotates in one direction only. (SHEET 18). Hereby, harnessing only one direction of motion of the swing.

DEVICE 12

A.2> Gear 9b is mounted on the axle of generator lO.Output of Generator 10 is connected to a rechargeable battery 1 1 via a full wave bridge rectifier circuit 10a. The rechargeable battery 1 1 is furtitur connected to an inverter 12. When the prime mover 'A' rotates, it rotates gear 9b. Hence electricity is produced; this charges a rechargeable battery 1 1 via full wave bridge rectifier circuit 10a. Any suitable electrical load requiring D.C supply 13b can be connected to the rechargeable battery 1 1 directly, or an inverter 12 can be connected to the rechargeable battery 1 1 and output of the inverter 12 can be connected to drive any electrical load requiring A. C supply 13a. In this case the generator's axle will rotate only in the clockwise or anti-clockwise direction as the prime mover 'A' transmits rotation of only one direction to gear 9A, which in turn rotates gear 9b in one direction and thus the generator's axle also rotates in one direction only. (SHEET 19). ). Hereby, harnessing only one direction of motion of the swing.

TYPE.B.> Construct the conventional swing with the prime mover 'A' as previously described. Gear 9A has a uni-directional bearing fitted at its centre. Gear 9A is mounted on the prime mover 'A' with the uni-directional bearing at its centre, due to which only one direction of motion of the prime mover 'A' will be transmitted to the Gear9A and not during the rotation of the prime mover in the opposite direction, THE prime mover 'A' will rotate freely during the rotation in the opposite direction. Gear 9A is coupled with another gear 9b, which is fixed on input shaft of gearbox G.B. The output shaft of the gearbox G.B has a gear 9c fitted on it. This is a common part of the construction for DEVICE 13, 14.

DEVICE 13

B.l> Gear 9c is used to drive any mechanical load. In this case gear9c will rotate only in the clockwise or anti-clockwise direction as the prime mover 'A' transmits rotation of only one direction to gear 9A, which in turn rotates gear 9b in one direction and thus the gear 9c also rotates in one direction only. (SHEET 20). ). Hereby, harnessing only one direction of motion of the swing.

DEVICE 14

B.2> Gear 9c is coupled with gear 9d which is fitted on the axle of the generator 10. Output of generator 10 is connected to a rechargeable battery 11 via a full wave bridge rectifier circuit 10a. The rechargeable battery 1 1 is further connected to an inverter. When the prime mover 'A' rotates due to the motion of the swing, it finally rotates gear 9d which is mounted on the axle of the generator 10. Hence electricity is produced; this charges a rechargeable battery 11 via a full wave bridge rectifier circuit 10a. Any suitable electrical load requiring D. C supply 13b can be connected to the rechargeable battery 1 1 directly, or an inverter 12 can be connected to the rechargeable battery 1 1 and output of the inverter 12 can be connected to drive any electrical load requiring A.C supply 13a. In this case the generator's axle will rotate only in the clockwise or anti-clockwise direction as the prime mover 'A' transmits rotation of only one direction to gear 9A, which in turn rotates gear 9b in one direction and thus the generator's axle also rotates in one direction only. (SHEET 21). Hereby, harnessing only one direction of motion of the swing.

We have described only gears as transmission devices and gear box as transmission systems for all the devices but we can use any type of transmission system such as pulley and belt, sprocket and chain, link and cam, etc or any type of transmission devices such as pulley, sprocket, cam, or link, etc as per their availability and requirement. (Sheet 22).

The complete full wave bridge rectifier circuit 10a is shown in sheet 24. The function of the capacitor (known as a 'smoothing capacitor') which is fixed after the diode bridge in the full wave bridge rectifier circuit is to reduce the variation in the output voltage and current from the full wave bridge rectifier circuit which charges the rechargeable battery 1 1 ,

The stand 14 (FIG A) and stand 15 (FIG B) are shown in SHEET 23. a, b, c, d are each square metal plate fixed with stand 14 and bolted to the ground with foundation bolts.
