Abstract

The windmill has a vertical shaft turning in bearings and through which a horizontal sail arm, freely movable, passes. Sails are fixed to the arm on opposite sides of the shaft and at roughly 90 deg. to each other. The sail (3) moving in the direction of the wind is vertical, and that moving against this direction horizontal. There can be a number of sail arms (2) one above the other and offset from each other, the windmill turning automatically with any wind direction, while the force of the wind acting on any sail is not restricted by a preceding one.

Windmolen.Windmill.

De uitvinding heeft betrekking op een windmolen met verti-cale as, waarbij deze as van een horizontale doorvoerde en vrij be-wegende roede is voorzien en waarbij deze roede aan beide kanten van de verticale as, is voorzien van een wiek, waarbij het van voordeel 5 is dat de beide wieken onder een hoek van b.v. 90 graden t.o.v. el-kaar, vast aan de roede zijn bevestigd.The invention relates to a windmill with a vertical axis, wherein this axis is provided with a horizontally fed and freely moving rod and wherein this rod is provided with a blade on both sides of the vertical axis, whereby it advantageously 5 is that the two blades are inclined at an angle of e.g. 90 degrees to each other, fixed to the rod.

De bestaande windmolens met verticale as, hebben het nadeel' dat het bestreken gedeelte van de wiek, met de wind mee, het arbeids-vermogen van de wind ontvangt, maar daarna met de wind tegen, een 10 groot gedeelte van het arbeidsvermogen weer verliest.The existing vertical-axis windmills have the drawback that the covered section of the wick receives, downwind, the working power of the wind, but then loses a large part of the working power downwind.

Een uitzondering hierop is de z.g."Chinese molen", hier wordt geprobeerd om de wieken,tegen de wind in, parallel met de wind te laten staan. Hierbij ontstaat echter het nadeel dat de wieken gaan klapperen, omdat ze los staan en daardoor weerstand van de wind onder-15 vinden. Tevens is hier het nadeel dat de wind, op de werkende wiek die loodrecht op de windrichting staat, nadelig wordt beinvloed door de vooryaande wiek.An exception to this is the so-called "Chinese windmill", here an attempt is made to leave the blades parallel to the wind, against the wind. However, this has the disadvantage that the blades will flap, because they are loose and therefore find resistance from the wind. There is also the disadvantage here that the wind, on the working wick that is perpendicular to the wind direction, is adversely affected by the forward wick.

• De onderhavige uitvinding beoogt om bovengenoemde nadelen op te heffen, waarbij de werking op eenvoudige, doch niettemin bij-20 zonder doeltreffende wijze wordt verwezenlijkt.The present invention aims to overcome the above-mentioned drawbacks, whereby the operation is realized in a simple, but nevertheless without effective manner.

Hiertoe wordt de molen volgens de uitvinding daardoor ge-kenmerkt, dat de ene wiek van de roede, parallel met de wind mee, ver-ticaal staat en de energie van de wind ontvangt, terwijl de andere wiek van de roede, parallel tegen de wind in, horizontaal staat en 25 daardoor geen weerstand heeft.To this end, the mill according to the invention is characterized in that one blade of the rod is vertical, downwind, and receives the energy from the wind, while the other blade of the rod is parallel to the wind. in horizontal position and therefore has no resistance.

Het is hierbij van voordeel als er meerdere"roeden, voorzien van wieken, verspringend boven elkaar in de verticale as wojrden aangebracht, zodat de molen zelfdraaiend is bij elke willekeurige windrichting en de wind, op een wiek, niet nadelig wordt beinvloed 30 door een voorgaande wiek.It is advantageous here if several rods, provided with blades, are arranged staggered one above the other in the vertical axis, so that the mill is self-rotating in any wind direction and the wind on a blade is not adversely affected by a previous one. wick.

De uitvinding zal hierna worden toegelicht aan de hand van de tekening, die een uitvoeringsbeeld van de windmolen, volgens de uitvinding weergeeft.The invention will be elucidated hereinafter with reference to the drawing, which shows an embodiment of the windmill according to the invention.

In deze tekening is de molen voorzien van drie roeden 2 en ,5 is de verticale as 1» draaibaar opgesteld in de kogellagers 4, die stevig gelagerd zijn in het huis 7. Elke roede 2, is 120 graden ver-draait t.o.v. een andere roede 2,In this drawing, the mill is provided with three rods 2 and, 5, the vertical axis 1 »is rotatably arranged in the ball bearings 4, which are firmly mounted in the housing 7. Each rod 2 is rotated 120 degrees relative to another rod 2,

De pijl C geeft de windrichting aan, zodat links van de lijn A-B, de wieken 3 verticaal zijn gedrukt en de energie van de 10 wind ontvangen, terwijl de wieken 3, rechts van de lijn A-B, hori- zontaal staan en daardoor zonder weerstand, tegen de wind in terug kun-nen draaien.The arrow C indicates the wind direction, so that to the left of the line AB, the blades 3 are pressed vertically and receive the energy of the wind, while the blades 3, to the right of the line AB, are horizontal and therefore without resistance, can turn back against the wind.

Als een roede de lijn A-B passeert, dan gaan de wieken 3 van deze roede 2 een positie innemen die ongeveer 45 graden is t.o.v.When a rod crosses line A-B, the blades 3 of this rod 2 will take a position that is approximately 45 degrees relative to

15 de verticale as 1.15 the vertical axis 1.

In de tekening wordt de kracht van de wiek 3 op de as 1 over-gebracht door een uitschulping in de wiek 3, die precies om de as 1 past.In the drawing, the force of the wick 3 is transferred to the shaft 1 by a scallop in the wick 3, which fits exactly around the shaft 1.

De conische tandwielen 5, brengen de opgewekte energie in 20 de as 1, via een koppeling 8, Over n^ar de dynamo 6.The bevel gears 5 transfer the generated energy into the shaft 1, via a coupling 8, across the dynamo 6.

Het zal duidelijk zijn dat elk ander werktuig aangesloten kan worden aan de koppeling 8*It will be clear that any other tool can be connected to the coupling 8 *

Ook is het duidelijk dat het vermogen van de molen, op een simpele en goedkope manier, vergroot kan worden door meerdere roeden 25 boven elkaar aan te brengen, tevens de roeden van grotere wieken te voorzien en het geheel aero dynamisch uit te voeren.It is also clear that the power of the mill can be increased, in a simple and inexpensive manner, by arranging several rods 25 one above the other, also providing the rods with larger blades and making the whole aero dynamic.

De uitvinding is niet beperkt tot het in de tekening weer-gegeven uitvoerings voorbeeld, dat op verschillende manieren binnen het kader der uitvinding kan worden gevarieerd.The invention is not limited to the exemplary embodiment shown in the drawing, which can be varied in various ways within the scope of the invention.
