Some Improved Windmills, or Wind Engines.
In the March number of the American Agriculturist pages 98-99, we discussed the value of tile force of the wind as utilized by the Windmill or Wind engine. At the same time a number of standard mills were presented, and their differences to scale extent pointed out. These did not include all the first-class mills; in fact, we did not even mention the "Halladay" Mill, made by the U. S. Wind Engine and Pump Co., Batavia, III., one of the pioneers, as many of our readers know, in the field of improved Windmills in this country. In the present article, without setting forth the importance of windmills in general—as that was given at some length last March—we simply wish to and to the list then commenced, some of the mills that have since come before our notice. The stain feature in the "Halladay" Windmill is the arrangement of the regulating gear by a sliding head, so that when the velocity increases the sails present less surface to the wind. The speed of the wind-wheel is dependent on the velocity of the wind, and the angle at which it strikes the sails. In the "Halladay" the exposed surface is diminished without changing the angle, thus keeping the pressure of the wind equally distributed on all sides of the wind-wheel, avoiding strain, and at the same time time being self-regulating.
Figure 1 shows this mill in position when at rest. When the sails are fully spread they take a radial position somewhat as in the wind-wheel shown in figure 2—that of the Eureka Mill, manufactured by the Kewanee Mfg. Co., New York City. This is a "solid wheel" mill, and, like all of its class, has certain points in its favor. It is claimed that ice and sleet do not interfere with their work as much as with the movable mills, which sometimes must be cleaned before they will start. It is a self-regulating mill, and simple in its construction.
