Abstract

A gravity operated electricity generator has a coil of wire encased in a non ferrous metal dish 10. The dish is fixed to frame 9 by a strut 22. Two magnets 13 and 15 are fixed to curved arms of cradle 16 which is connected to the top of frame 9 by a movable ball joint 5. When the frame is tilted from vertical the dish moves through the attracting magnetic field between the two magnets and produces an E.M.F. at the terminals of the coil. A peg 18 is positioned to move only within the restricting ring 19 in order to stop cradle 16 hitting strut 22. Alternatively as shown in Fig 1 the magnets 13, 15 may be arranged to freely slide on dishes 10, 8 secured in a tiltable frame, dish 10 containing coil 12. <IMAGE>

Description

GRAVITY OPERATED ELECTRICITY GENERATOR This invention relates to a gravity operated electricity generator.
It is well known that boats and buoys spend a considerable amount of time rocking, rolling and pitching in the water. This i-nvention utilizes this motion to move coils of wire through magnetic fields in order to generate electricity.
According to the present invention there is provided a gravity operated electricity generator comprising a non ferrous metal dish. Encased in this dish is a circular coil of wire. A frame to which the dish is fixed. The frame also has a curved dish fixed near to its base. Two curved circular permanent magnets which can slide freely on the dishes. These magnets have a smaller diameter than the inside diameter of the circular coil of wire. The frame when tilted from vertical being able to move the dish with the coil encased between the two magnets and produce an E.M.F. at the terminals of the coil.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Drawing 1/4 figure 1 shows a side view of the dish and coil.
Drawing 1/4 figure 2 shows a plan view of the dish and coil.
Drawing 1/4 figure 3 shows a side view of one magnet.
Drawing 1/4 figure 4 shows a plan view of one magnet.
Drawing 2/4 figure 1 shows the position of the dishes in the frame with the magnets in position on the frame.
Drawing 2/4 figure 2 shows the position of the magnets and coil when the frame is tilted.
Referring to the drawing 2/4 figure 1 the gravity operated electricity generator comprises a frame 9.
A non ferrous metal dish 10 is fixed to frame 9.
Encased in non ferrous metal dish 10 is a circular coil of wire left some distance below non ferrous metal dish 10 is fixed a non ferrous metal dish 8.
A curved circular permanent magnet 13 is positioned on the top curved surface of non ferrous metal dish 10. It can slide freely on the top surface of the non ferrous metal dish 10. A second curved circular permanent magnet 15 is positioned on the top surface of non ferrous metal dish 8 it can slide freely on the top surface of non ferrous metal dish 8. The position of the poles of the curved circular permanent magnets 13 and 15 are such as to provide an attracting magnet' field between each other.
Referring to drawing 2/4 figure 1. This shows the relative positions of the coil 12 and magnets 13 and 15 when frame 9 is in an upright position. No E.M.F. is generated in this position.
Drawing 2/4 figure 2 shows a position of frame 9 when it is fixed to a boat deck 17 and the boat is rocking in the direction of arrow 25. As the boat rocks from side to side the circular coil 12 which is encased in non ferrous metal dish 10 also rocks from side to side. The two sliding curved circular permanent magnets 13 and 15 being acted upon by gravity will tend to remain in their lowest position. During the time the left hand side of the circular coil of wire 12 is moving through the magnetic field between the two curved circular permanent magnets 13 and 15 an E.F5.F. is generated and is available at the terminals (not shown) of the circular coil of wire 12.During the time the boat is rocking back in the direction of arrow 26 and the left hand side of the circular coil of wire 12 is moving through the magnetic field between the two curved circular permanent magnets 13 and 15 an E.M.F. of opposite polarity is generated and is available at the terminals (not shown) of the circular coil of wire 12. As the boat continues to rock in the direction of arrow 26 and the right hand side of circular coil of wire 12 is moving through the magnetic field between the curved circular permanent magnets 13 and 15 an E.M.F. is generated and is available at the terminals (not shown) of circular coil of wire 12. As the boat rocks back in the direction of arrow 25 an E.M.F.
of opposite polarity is generated as the right hand side of the circular coil of wire 12 moves through the magnetic field between the curved circular permanent magnets 13 and 15. This E.M.F. is available at the terminals (not shown) of the circular coil of wire 12. Irrespective of which direction the boat rocks and rolls an E.M.F. will be generated in the circular coil of wire 12 if the amplitude of the swing is sufficient to move the circular coil of wire 12 through the magnetic field between the two curved circular permanent magnets 13 and 15.
Only one coil and two magnets have been used to illustrate the present invention. It is understood that any required number of coils, dishes and magnets may be used with a suitable frame to provide an E.M.F. in other embodiments of the invention.
According to a second embodiment of the present invention there is provided a gravity operated electricity generator comprising a non ferrous metal dish. Encased in this dish is a circular coil of wire, bye non ferrous metal dish is fixed to a frame by a non ferrous metal curved strut, swo curved circular permanent magnets that are fixed to curved arms of a non ferrous metal cradle which is connected to the top of the frame by a movable ball joint. On top of the ball joint a restricting peg positioned to move inside a restricting ring which is fixed to the top of the frame. The frame when tilted from vertical being able to move the dish with the coil of wire encased between the two magnets and produce an E.M.F. at the coil terminals.
A second embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Drawing 3/4 figure 1 shows a side view of the frame and cradle in a vertical position.
Drawing 3/4 figure 2 shows the restrictor peg in the restrictor ring.
Drawing 4/4 figure 1 show a dish with three coils encased in it.
Drawing 4/4 figure 2 shows a dish with six magnets in it.
Referring to the drawing 3/4 the second embodiment of the gravity operated electricity generator comprises a frame 9, a cradle 16 that can swing freely from a ball joint 5 situated in the top of the frame 9. Two permanent magnets 13 and 15 are fixed to two curved arms of the cradle 16 and are positioned to be able to move just above and below a curved circular non ferrous metal dish 10 in which is encased a multi turn coil of wire (not shown). The non ferrous metal dish 10 is fixed to the frame 9 with a non ferrous metal strut 22 the cradle is of a non ferrous metal. On top of the ball part of the ball joint 5 is a metal peg 18 positioned to be in the centre of a metal restricting ring 19 which is fixed the top of frame 9. This central position being so when the frame 9 and the cradle 16 are in the position as shown in figure 1. The two curved arms of cradle 16 the curved strut 22 the curvature of the two permanent magnets 13 and 15 and the curvature of dish 10 are all concentric to the centre of ball joint 5.
In order to generate electricity the frame 9 of the gravity operated electricity generator is fixed to the deck of a boat or inside a buoy. When the frame 9 tilts from vertical due to rocking and rolling of the boat or buoy the two magnets 13 and 15 tend to stay in their lowest position. The coil (not shown) encased in dish 10 will move through the magnetic field between the magnets 13 and 15. If the amplitude of the swing is great enough then an E.b;.F. will be produced at the terminals of the coil (not shown) irrespective of which direction the boat or buoy rocks, rolls or pitches.
Referring to drawing 3/4 figure 2 and 1. To avoid any contact between strut 22 and the cradie 16 due to circular movement of cradle 16 in the direction of arrows 25 and 26 with respect to frame 9 a peg 18 is fixed to the top of the ball of ball joint 5.
The peg 18 is restricted in its movement by the restricting ring 19 which is fixed to the top of frame 9.
Referring to drawing 4/4 figure 1 which shows three multi-turn coils 12 (one turn only shown) encased in a non ferrous dish 10.
Referring to drawing 4/4 figure 2 which shows one of a complementary pair of magnet arrays for use with the dish 10 and coils 12 and shown in drawing 4/4 figure 1.
Provided (but not shown) are other embodiments of the invention in which any required number of magnet arrays and coil formations are supplied.
Electro-magnets may be used if required. The position of the magnets and coils may be reversed in some embodiments.
The criterion being to avoid, if possible, generating simultaneously opposed induced currents in any particular coil.
