| Abstract:
In the construction of windmills it is usual to transmit the power of the wind-wheel to the machinery below by the employment of gearing, or a crankshaft and pitman. These arrangements, however, are both objectionable, for the following reasons: First, the friction attending the use of the gearing is so great as to impede the force of the mill, while the irregular movements of the wind-wheel are liable to break out the teeth of the gears; second, the leverage due to the arrangement of the gears eccentrically to the vertical center of the mill tends to throw the wind-wheel out of the wind, and thereby decrease its efficiency, and impart a variable motion to the machinery below; third, the employment of the crankshaft and pitman imparts an irregular motion to the machinery, owing to the dead-points of the crank, while the lateral vibration of the pitman creates too much friction of the parts through which it operates.
My invention is designed to avoid these objections, for the purpose of increasing the efficiency of the mill, and decreasing its cost of construction. To this end the invention consists, first, in transmitting the power of the wind-wheel to the machinery below by a wire rope or other suitable band , guided by a series of grooved pulleys, arranged, with relation to each other, so that the pulleys shall guide the rope down through the center of the mill in vertical lines nearly touching each other, to prevent binding should the rope become twisted, and so that the friction of the wheel-shaft in its bearings shall be reduced by the lifting action of the rope in its passage over the pulleys ; secondly, in the provision of means for preventing the wire rope from being duly tightened should it become twisted by the rotation of the mill-head, and for taking out the twist; thirdly, in the provision of means for operating the vane or rudder positively in both directions with reference to the horizontal axis of the wind-wheel and lastly, in the combination of various parts.
Claim:
The combination of the secondary guide-pulleys with the grooved pulley on the shaft of the wind-wheel, arranged with relation to each other. |
