  " Turbine à vent verticale" 
L'invention se rapporte à une turbine à vent verticale du type connu, muni d'une roue à vent reposant dans un bâti et possédant un noyau muni d'aubes. 



   L'invention a pour but de construire cette turbine à vent de manière à obtenir le rendement le plus élevé possible, c'est-à-dire que l'énergie motrice du vent soit utilisée le mieux possible pour entraîner la roue à aubes. Suivant l'in vention, les aubes s'étendent, en sens radial, approximative - ment le long de la moitié du diamètre du noyau, et elles ont un profil approximativement en L ou angulaire, chaque profil étant composé d'une jambe intérieure courbée et tangente au noyau, et d'une jambe extérieure, courbée dans le même sens mais plus longue, cesjambes étant raccordées l'une à l'autre par une partie courbée de petit rayon. 



   Cette application et conformation des aubes a l'avantage que le vent, après avoir exercé son action propulsive d'abord 

 <Desc/Clms Page number 2> 

 sur la jambe en L courte, pendant la rotation continue de la roue, continue son action sur la jambe longue et alors, en raison du fait que le noyau, par rapport 'aux aubes, possède une grande dimension, exerce une forte action de levier sur la roue ce qui aide à la rotation. Il y a une proportion favo- rable à la rotation entre le moment résistant et le moment moteur. Des aubes en forme de L sont connues en elles-mêmes , cependant la forme spéciale décrite plus haut est nouvelle ainsi que la combinaison avec un noyau d'un diamètre relati - vement grand. 



   Le dessin montre une forme d'exécution de l'invention à titre d'exemple. 



   La fig.l représente en élévation une turbine verticale à vent suivant l'invention. 



   La fig. 2 montre une vue en plan correspondante. 



   La turbine possède une roue à vent G, reposant dans un bâti. Cette roue est fixée sur un arbre 1 vertical et se compose d'un tambour ou noyau 2 muni d'aubes 3 radiales et d'un profil caractéristique. Le profil des aubes est approxi - mativement en forme de L, les deux jambes du L étant courbées et sejoignant par une courbe d'un petit rayon. La jambe   4,   fixée sur le tambour, est tangente par rapport à la surface cylindrique du tambour ; les extrémités extérieures des aubes sont raccordées l'une à l'autre par des anneaux 5, par exemple en métal feuillard. 



   L'arbre 1 repose dans des paliers 6, 7 et 8 et sur un pivot 9, tandis qu'un palier 10 supérieur est raccordé au moyen de tiges 11 à des mâts 12, fixés dans le sol. Des haubans 13 contribuent à la rigidité de   l' ensemble.   La transmission de mouvement de l'arbre 1 de la roue à l'arbre 14 moteur de transmission est obtenue au moyen de roues coniques 15 et 16, mais pourrait être obtenue aussi d'autre manière.

  "Vertical wind turbine"
The invention relates to a vertical wind turbine of the known type, provided with a wind wheel resting in a frame and having a core provided with blades.



   The object of the invention is to construct this wind turbine so as to obtain the highest possible efficiency, that is to say that the driving energy of the wind is used as best as possible to drive the paddle wheel. According to the invention, the vanes extend, in a radial direction, approximately along half the diameter of the core, and they have an approximately L or angular profile, each profile being composed of a curved inner leg. and tangent to the core, and of an outer leg, curved in the same direction but longer, these legs being connected to each other by a curved part of small radius.



   This application and conformation of the blades has the advantage that the wind, after having exerted its propulsive action first

 <Desc / Clms Page number 2>

 on the short L-leg, during the continuous rotation of the wheel, continues its action on the long leg and then, due to the fact that the core, in relation to the vanes, has a large dimension, exerts a strong lever action on the wheel which helps the rotation. There is a favorable proportion to the rotation between the resistance moment and the driving moment. L-shaped vanes are known in themselves, however the special shape described above is new as well as the combination with a core of a relatively large diameter.



   The drawing shows an embodiment of the invention by way of example.



   The fig.l shows in elevation a vertical wind turbine according to the invention.



   Fig. 2 shows a corresponding plan view.



   The turbine has a wind wheel G, resting in a frame. This wheel is fixed on a vertical shaft 1 and consists of a drum or core 2 provided with radial vanes 3 and a characteristic profile. The profile of the blades is approximately L-shaped, the two legs of the L being bent and joining by a curve of a small radius. The leg 4, fixed to the drum, is tangent to the cylindrical surface of the drum; the outer ends of the blades are connected to one another by rings 5, for example made of strip metal.



   The shaft 1 rests in bearings 6, 7 and 8 and on a pivot 9, while an upper bearing 10 is connected by means of rods 11 to masts 12, fixed in the ground. Guy wires 13 contribute to the rigidity of the whole. The transmission of movement from the shaft 1 of the wheel to the transmission motor shaft 14 is obtained by means of bevel wheels 15 and 16, but could also be obtained in other ways.
