Patent Document

[0001]    This application claims benefit of provisional application 60/837,923, filed Aug. 16, 2006. 
     
     BACKGROUND OF THE INVENTION 
       [0002]    The generation and transmission of electrical power is a constant concern. Providing electrical power for the numerous needs of residential, commercial and industrial applications is a constant concern. These concerns include the noise and pollution associated with the generation of electricity and the problems in transmission over long distances. 
       SUMMARY OF THE INVENTION 
       [0003]    An electrical generator utilizes power produced by falling weights. Falling weights are connected to long arms which turn a shaft. The shaft, through a series of gears, provides power to the generator.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0007]    A series of weights  12  are connected to a rack  14 . While three weights are shown, any number of weights may be utilized. An arm  18  extends from each arm, each connected to a shaft. The end of the arm moves in an arc while the weight moves in a line. To account for this difference, the arm attaches to the weight in any suitable manner. The end of the arm may attach to the weight by a cable or a rod pivotally connected to the weight, the arm, or both. Also, the arm may be made of telescoping sections, allowing the length of the arm to vary. 
         [0008]    The shaft is connected to a first gear  22 . The first gear  22  intermeshes with a second gear  24 , a compound gear having a small gear turning with a larger gear. As the first gear  22  meshes with the smaller gear, an increase in rotational speed is gained. The larger of the second gear connects with the smaller gear of a third gear  26 . The third gear set, likewise, is a compound gear having a small gear meshing with the larger of the second gear to again increase rotational speed. The larger gear meshes with an electric generator  30 . Any number of gears may be used in the gears train between the shaft and generator in order to produce a desired rotational speed from the shaft. 
         [0009]      FIG. 2  shows the end view where the relationship between the weights is seen. The weights are suspended from the rack by a cable  16 . After the weight  12  has reached its bottom most extent, it is raised back up by a secondary power source (not shown). In the view of  FIG. 2 , one weight is shown in its uppermost position, a second weight is shown in its lowermost position, and a third weight is shown in a middle position. In order that the arms turn the shaft  20  on its downward journey but still be able to be raised, the arm  18  is connected to the shaft  20  by a ratcheted spline. The ratcheted feature allows the arm to drive the shaft  20  yet still be raised without affecting movement of the shaft  20 . 
         [0010]    The weights may be in any position at any given time, including all weights in its uppermost position. The weights may be raised during off-peak electrical usage time, allowing for the later generation of electricity during peak usage to reduce the strain on the electrical system. Also, the secondary power source may be powered by a renewable power source, such as hydropower, allowing for the conversion of hydropower to electricity, or solar powered, allowing for the raising of weights during power production of the solar panels and generation of electricity when the solar panels are not producing. The weights may also be raised manually, if the weights are of a size making this feasible. 
         [0011]      FIG. 3  depicts the platform  28  which supports the generator, gears and shaft  20 . The distance between the platform  28  and rack  14  may be made any distance that is both desirable and feasible. 
         [0012]    While the invention has been disclosed with reference to a preferred embodiment, variations and modifications would be apparent to one of ordinary skill in the art. Such variations and modifications are encompassed by the invention.
