Known similar motors, which work by means of the gravitation are disclosed, among others, in US 2003/0155770 Al and US 2013/0239743 Al . However, these motors are limited to be possible to be extended to greater motors by the fact that the number of arms are limited to the particular shape of hub parts as well as that the motions of weights in slot-shaped arms among others things cause beats and thuds from freely movable weights carried in the slots. In addition, accurately arranged guidings for the weights are required, at the centre as well as between the external ends of the arms and the centre of the motor.

Iris gravity motor concerns weights oscillatingly carried by lines and which revolve between two rings around a shaft. There is no guiding of the weights, but these are hanging freely between the pair of lines.

By a motor known by US 2003/015 57 700 Al, reference is made to a gravity motor wherein fixed arms (38) emanating from a hub have slots (39) along the length extension of the arms. Weights (50) are guidingly received in said slots (39). Guide plates (70, 80) having guide surfaces (71, 81) are supported from the tip of the arms toward the inner portion of the arms and toward the hub, and from the hub and the inner portion of the arms out toward the tip of the arms again, respectively. Said motor is in that connection driven by magnets when the weights move around the hub (34) . The purpose of the guidings according to said US 2003/015 57 700 Al is different from purposes of the guidings for the motor according to the present invention. In said known motor, it is aimed to get the common poles of the magnets against each other to provide repellent force between magnets supported by the guidings (70, 71) arranged therefor unlike guidings according to the present invention wherein the oscillating weights are guided to oscillate away from the periphery of the motor inward toward the shaft of the motor and further in an oscillatory motion out toward the periphery again, etc., around again.

The main object of the present invention is to provide a motor that solves among other things the problems mentioned above in a reliably working way and that also allows simple extension to increase power output if required and desired.

Said object is achieved by means of a motor according to the present invention, which

essentially is characterized in that uniform holders provided with weights are displaced in the direction of rotation, as seen from holder to holder, said weights being formed of rotatably journalled turnable rollers or wheels carried by turnably journalled pendulum arms, that the bearing mountings of said pendulum arms are situated at and distributed along the periphery of said holder as well as that guidings for said oscillating rollers or wheels are arranged at and extending along the periphery as well as centre area of said holder toward the shaft, the motor comprising means for starting, e.g., an

additional motor, wind turbine and means for the recovery of energy from the gravity motor in question, e.g. a transformer as well as a gear, so that only minor impact force pulses are required for the motor to be able to continue to be driven by itself, e.g., by means of an electric motor, which collects energy from the mains, or a compressor, which is utilized to, e.g., blow on a turbine connected to the shaft of said motor or another part of the movable holders of the motor.

The technical effect of the present invention is clearly indicated in the description: Thus:

* With the purpose of obtaining continuous driving power from the motor 101, uniform holders A-H provided with weights 1, 5, 9; 2, 6, 10; 3, 7, 11; and

4, 8, 12 are displaced in the direction of rotation 20, for instance as is shown in Fig. 5 in the assembly drawing of the various weights 1-12.

* For starting the motor 101 and/or for being able to extract motion and power from said motor

101, the shaft 102 supports a chain wheel 21 and/or a pulley 22.

* Furthermore, the motor 101 comprises means 23 for starting the motor 101 in question, e.g., an additional motor of a suitable kind, e.g., a wind turbine ,

* as well as means 24-25 for providing recovery and storage of energy from the gravity motor 101 in question according to the invention, e.g. a transformer.

* Only minor impact force pulses are required for the motor 101 to be able to continue to be driven by itself, e.g., by means of an electric motor 23, which collects energy from the mains 27, or a compressor 29, which is utilized to, e.g., blow on a turbine 30 connected to the shaft 102 of said motor or another part of the movable holders A-H of the motor.

The function of the motor 101 is that when the motor has been started to revolve in the direction 20, the holders A-H including arms 13 ¹ -13 ¹² and weights 1-12 carried thereon move in the same direction 20. Namely that:

The weights are distributed displaced along the holders and moreover evenly so that a continuous drive action is achieved for said holders A-H, such as at a crankshaft.

The invention is described below in the form of a preferred embodiment example, reference being made to the accompanying drawings, in which

Fig. 5 schematically shows the motor and movable weights included therein in different operating modes, as seen when the appurtenant holders are rotated clockwise.

A so-called gravity motor 101, which comprises a shaft 102 supporting a number of disc-shaped holders A-H, which in turn support a plurality of movable weights 1-12 thereon, comprises according to the present invention weights of a particular kind and particularly formed bearing mountings therefor. Said weights 1-12 suitably consist of iron, lead, or another heavy material. More precisely, said weights 1-12 are formed of rotatably journalled and turnably carried rollers or wheels, which are carried by turnably journalled pendulum arms 13 ¹ -13 ¹² . The pivots 14 ¹ -14 ¹² of said pendulum arms are situated at and distributed along the periphery of said holders A-H. Said pendulum arms 13 -13 ¹² are manufactured from a light material, preferably aluminium or another suitable light metal material for said purpose. Guidings 15A-15H; 16A-16H intended for said oscillating rollers or wheels are arranged at the periphery 17 of said holder and arranged to extend along the periphery 17 as well as centre area 18 of said holder.

Said guidings 15A-15H; 16A-16H are carried by the respective holder A-H and/or are carried by a stand 19 for the motor 101. Provided guide ways for said weights formed as wheels or rollers are arranged to have low friction by means of a suitable material therefor. They may also be lubricated with suitable agents, e.g. by air, oil, or another suitable agents. They may also be formed of roller conveyors of a suitable design.

A said shaft 102, which preferably extends through all holders A-H, extends essentially horizontally and said pendulum arms 13 ¹ -13 ¹² have such a length L that rollers or wheels carried thereby are arranged to abut against said shaft 102 upon passing the same when the holders A-H are rotated in the direction of the arrow 20 in the drawings, i.e., that the arms 13-13 ¹² have such a length L that they reach all the way up to said shaft 102 from the respective bearing mounting 14 ¹ -14 ¹² of the arms at the periphery of the holder.

Said rollers or wheels are essentially evenly distributed along the respective holders A-H.

With the purpose of obtaining continuous driving power from the motor 101, uniform holders A-H provided with weights 1, 5, 9; 2, 6, 10; 3, 7, 11; and 4, 8, 12 are displaced in the direction of rotation 20, for instance as is shown in Fig. 5 in the assembly drawing of the various weights 1-12. For starting the motor 101 and/or for being able to extract motion and power from said motor 101, the shaft 102 supports a chain wheel 21 and/or a pulley 22. Furthermore, the motor 101 comprises means 23 for starting the motor 101 in question, e.g. an additional motor of a suitable kind, a wind turbine as well as means 24-25 for providing recovery and storage of energy from the gravity motor 101 in question according to the invention, e.g. a transformer. In addition, a gear 26 therefor of, e.g., known type may be arranged at the motor 101 according to the invention.

A said motor 101, which is arranged to be driven by the gravity force, consists of simple parts and is arranged to work without problems once the motor 101 has been started. Only minor impact force pulses are required for the motor 101 to be able to continue to be driven by itself, e.g., by means of an electric motor 23, which collects energy from the mains 27. Also e.g., a compressor 29 may be utilized to, e.g., blow on a turbine 30 connected to the shaft 102 of said motor or another part of the movable unit A-H of the motor.

Energy, which the motor 101 produces, may in turn be delivered to the mains 27 from an electric generator 24 and a transformer 25 after a gear change via a gearbox 28 for recovered energy.

The function of the motor 101 is that when the motor been has been started to revolve in the

direction 20, the holders A-H having arms 13 ¹ -13 ¹² and weights 1-12 carried thereon move in the same direction 20.

The weights 1-12, which also are rotatably journalled at the free ends 31 ¹ -31 ¹² of the respective arms via e.g., ball bearings 32 ¹ -32 ¹² , are supported by the respective holders A-H in groups 1, 5, 9; 2, 6, 10; 3, 7, 11 and 4, 8, 12, respectively, and so on, if more than, e.g., four holders are arranged. As the holders rotate, the arms 13 ¹ -13 ¹² having weights 1-12 journalled thereon move in the direction of motion 20. To limit the turning out of said arms and weights toward the periphery of the holder, stoppers 33 are arranged on the holders A-H or on the stand 19 of the motor, the function of which is clearly seen in Figs. 6-9. The weights 1-12 are guided toward the appurtenant guidings 15A-15H; 16A-16H for the respective holders A-H and are guided along the same as the holders A-H are rotated in the direction 20 around the shaft 102. Thus, it is shown in Fig. 5 that the weight 1 freely moves downward although retained by the appurtenant pendulum arm 13 ¹ . The weight 5 is held by the arm 13 ⁵ , which abuts against the support 33, so that the weight 5 will, when the holder A rotates, come to abutment against the guiding 15A first. The weight 9 has pendulated down to the guiding 16A and then abuts against the centre guiding 16A until the shaft 102 takes over the support work. Thus, when the weights have passed the shaft 102, the weights oscillate freely and aim at pulling along the holders A-H in the drive direction 20. The same applies to all holders A-H having weights 1-12 only that the weights are

distributed displaced along the holders and moreover evenly so that a continuous drive action is achieved for said holders A-H, such as at a crankshaft. If more power is desired of the motors, only more holders are coupled to the shaft so that an even distribution is obtained.

The function and nature of the invention should have been clearly understood from the above- mentioned and also with knowledge of what is shown in the drawings but the invention is naturally not limited to the embodiments described above and shown in the accompanying drawings. Modifications are feasible, particularly as for the nature of the different parts, or by using an

equivalent technique, without departing from the

protection area of the invention, such as it is defined in the claims.
