Technical problem The technical problem that is resolved with this invention consists of the following: How to construct a device that will, with its structure, enable that the kinetic energy of weights symmetrically placed around the shaft eccentrically moved in the cylindrical housing be used to obtain mechanical force which may be used for various purposes? At the same time, how could this energy be as economic as possible and avoid environment pollution, or, how the process of obtaining such an energy could be developed without noise and damaging by-products? The condition of technique Technological development has caused an increasing consumption of energy that has practically always been insufficient to meet growing needs for it.

Steam energy that was obtained by burning firstly wood and coal and then oil was then supplemented with the energy obtained from the operation of hydraulic machines. During this process the principle was used that the adequate fall of water be transformed in rotational movement, or useful work that is defined by the difference of kinetic energy during inflow and outflow. Such energy is much cheaper and ecologically most acceptable with regard to the energies obtained with other methods. But, there must be natural conditions to obtain such energy (water currents and natural or artificial geodetic falls). Also, it is necessary to provide suitable transformers and electric long distance lines for the transmission of such energy and this makes its cost much higher and limits its use, as there must be a link between the source of energy and consumers.

In developed countries, since recent times, at the places that lack energy resources (coal, heavy fuel oil and water currents), nuclear power plants have been built. They increase energy resources of those countries and but are also a factor in further and more intensive pollution of human environment. This environment has already been largely polluted and ecologically put at risk by various by-products of energy obtainment as a result of combustion, of heavy fuel oil and coal in particular. The energy obtained in nuclear power plants has proved to be"the filthiest"as the elements appearing after the chemical reactions in nuclear reactors, known as nuclear waste, have raised an exceptionally complex problem before mankind. It is the problem of their storage that is costly, complicated and requires the engagement of expert teams and the planning of special space and facilities. Additionally, all this leaves longtime consequences for human environment.

The above has persuaded the author of this invention to construct a new device that is relatively simple but effective. It is, first of all, ecologically good and it resolves the above technical problem. Despite a detailed check up of all available patents and non-patents, foreign and Yugoslav documentation and other technical documentation, no other technical solution similar to this patent application has been found.

Explanation of the real meaning of this patent The real meaning of this patent is as follows: According to the author's idea a simple motor has been constructed. It consists of a closed housing in which an eccentric step-shaped shaft (4x2") has been placed with radially made smooth levers. Over them are fitted sliding bushes. On their external sides they are fixed to cylindrical flanges. The upper ends of those flanges are extended into semi-spherical weights and their round ends are turned to the housing case. In most favorable examples they have three round bearings each in which balls are placed. Around smooth levers there are spiral springs that constantly make a pressure on the bottom of flanges. When pressuring the flanges those spiral springs also make a pressure on semi-spherical weights to the cylindrical housing case.

It is important for such ecological motor that it does not have to be stationary and it can have various dimensions that define its force. Other recognized motors have weights that during rotation are at an equal distance from the rotation center. The innovation of this patent lies in the fact that opposite weights rotating in this motor, according to the author's idea, are made in such a manner that they can move, or that one of them is closer and the other is at the same time further away from the rotation center. According to the inventor's idea this device is made so that the weight that is further away from the rotation center operates positively and the closer weight during the phase of lifting to the certain height operates negatively. The difference between those two operations is useful operation, or the turning of the shaft that emerges as a resultant of kinetic effects of all levers. This turning of the shaft is transformed into the rotational or mechanical energy that could be further used for various purposes. It is clear that the achieved rotational moment, in addition to the abovementioned negative operation, also reduces losses that are a result of all kinds of frictions due to the operation of the elements of this device. The ecological motor, according to this invention, has a number of advantages with regard to the recognized technical solutions in this subject matter. The following are some of them: - A much greater economisation during its use, - A very low cost of production due to a simple and compact structure fully made of local materials, - A potential serial and highly serial production even in small specialized metal processing factories, - Full independence from meteorological and geodetic conditions, - From the ecological point of view it is fully nontoxic and it contributes to the conservation of human environment.

A brief description of drawings and plans To understand this invention more easily and to show how it can be made real, the author refers to the enclosed plan that relates to the ecological motor operating on the principle of eccentric rotation of weights around the common axis and relating spiral springs: - Drawing 1 shows the vertical transversal cross-section of a simple view of the ecological motor from its front side, - Drawing 2 shows the horizontal transversal cross-section of a simple view of the ecological motor from the side, - Drawing 3 shows the vertical transversal cross-section of a simple view of the ecological motor from the front side where dimensions of rotating elements are the same as shown on Drawing 1, but the diameter of the housing case is somewhat larger.

A detailed description of the patent By looking at the drawings of the enclosed plan one can see that the ecological motor works on the principle on eccentric rotation of weights around the common axis and relating spiral springs 5 and that it consists of the following: 1 cylindrical housing closed on both sides with side covers 13 on which on the internal side are opposite eccentrically located bearings 14 in which are placed bearings 12 through which a step-shaped shaft 2 passes. In its strengthened middle part 16 are radially derived cylindrical openings 15 with indented threads in which smooth lever 3 are fixed by bolting. Over them, in the part leading to the shaft 2, are firstly placed buffer rings 9 and elastic spiral springs 5.

With their upper end the springs 5 lean on the lower ends of hat-shaped flanges 4 that in their lower part have fixed sliding bronze bushes 8, which are of a slightly larger diameter that is the diameter of levers 3 that enable the flanges 4 to longitudinally move in both directions along the levers 3. At the other end of the hat-shaped flange 4 there is a ring-shaped reinforcement 17 that is inserted in the ring-shaped recess of the lower flat part of the semi-spherical weight 6 and fixed to it with bolts 18.

Drawing 2 shows that the movement of the flange 4 is limited by way of the highest compression 5 on one side and with a safety ring 10 on the other side. This ring is fixed to the upper end of the lever 3 by way of a safety bolt 11. On the semi-spherical weight 6, on the upper side, are symmetrically and most advantageously derived three semi-spherical bearings. One is in the center on top and two are symmetrically distanced from it by 30°. In them are inserted three balls 7 that in a certain position of weights 6 and springs 5 touch the cover of the cylindrical housing 1 and by turning they enable an undisturbed rotation of semi-cylindrical weights 6.

The method of work of the ecological motor operating on the principle of eccentric rotation of weights 6 around the common axis and effects of relating spiral springs 5 is simple and functions in the following manner: The semi-spherical weight 6 and its counter-weight 6', moved by some initial force sufficient to take them out of the equilibrium position, start moving to the left (opposite to the course of the clock hand). During this movement semi-spherical weights 6 and 6, move in such a way that the weight 6, which was at the highest point of y-axis, has a descending course after activation and thus, under the effect of the gravitation force, carries out the turning of the shaft 2. At the same time the weight 6', which was at the lowest point of y-axis, starts moving upward conquering the gravitation force. At point A of the drawing 1, the semi-spherical weight 6, over the ball 7, starts touching the cover 19 of the housing case 1. As the shaft 2 is placed eccentrically, due to the further rotation of balls 7 on the cover 19, there comes the cover pressure 19 on the semi-spherical weights 6.

They consequently have an effect on the springs 5 by slowly compressing them. The semi-spherical weights 6, with the sliding of slide bushes 8 over smooth levers 3, move to the step-shaped shaft 2. In this way, the weight 6, when in its descending movement, when the positive effect of the gravitation force is used for the turning of the shaft, is found at the longer end of the lever in relation to weight 6'.

Due to this the latter weight is easily lifted by the former one during the rotational movement, from the lower point to the upper point of y-axis. This practically leads to positive operation that is reduced by the friction force and strength of materials that move and take part in the operation of this device. At the moment when the smooth levers 5'overlap with x-axis the spiral springs 5 under the weights 6 are fully free whereas the spiral springs 5'under the weights 6'are totally compressed.

During the further movement compressed springs 5'assist the further turning of the shaft 2 with levers 3 because they tend to get free of the stressed condition. This is made easier by the balls 7 that are located at the edges of semi-spherical weights 6, which due to the Point to point touch along the cylinder cover 19 move under minimum friction resistance.

The circle of turning of the semi-spherical weight 6 is closed partially because of inertia movement of semi-spherical weights 6 and partially because of the effects of stressed springs 5. The increase of the number of smooth levers 3, which are symmetrically derived by the number (4x2") only leads to the summing of the positive effect of the motor's operation, or, to a more synchronized and easier turning of the step-shaped shaft 2.

The method of industrial and other applications of this invention Industrial application of this invention is absolutely possible in metal processing factories and even in well-equipped metal processing workshops-on The basis of documentation that the experts in this subject field may prepare by using descriptions and drawings from the subject application of this invention. This invention is suitable for serial production.

Depending on the intended use of these motors the essential structural characteristics are defined, such as the weight of weights, their number and dimensions of the cylindrical housing. All those characteristics have an essential effect on the increase of the effective force that is gained by such motors.

It must be mentioned that an enormous importance of the use of these motors is evident not only when an individual is in question but also the public community as the substitution of the now common motors in use, which significantly pollute human environment, would achieve essential ecological results in the preservation of human environment.
