JOHN CHALLBERG, OF MAROY, IOVA.
WlNDMILL.
SPECIFICATION forming part of Letters Patent No. 317,298, dated May 5, 1885.
' Application filed May 24, 1883. (No model.)
To all whom it may concern:
Be it known that I, J OHN CHALLBERG, a citizen of the United States, residing at Marcy Township, in the county of Boone and State of Iowa, have invented certain new and useful Improvements in Windmills, of which the following is a specification, to wit:
This invention relates to an improvement in windmills; and it consists in certain novel peculiarities of construction and arrangement, whereby the speed of the wheel is automatically controlled, the blades thrown into or out of the wind, and the wheel started and stopped at will, substantially as will be hereinafter more fully set forth. 7
In order to enable others skilled in the art to which my invention relatesto make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which Figure l is a perspective View of my invention; Fig. 2, a central vertical section of the same. Fig. 3 shows two views of the blade, and Fig. 4 a detail of part of the device for regulating the fans.
A represents a windmill-tower of any suitable construction, which is capped by a metal ring, A, having an annular groove, (4, upon its inner side, which receives a flange, b, up on the periphery of a second ring, B, which forms the turn-table. In lugs b upon this ring B is journaled the shaft 0 of the windwheel which is cranked just over the center of the tower and provided with a pitman, 0, running down a suitable distance and jointed to the rod 0 which passes down to the ground and is connected to any desired machinery.
Upon the shaft 0 is placed the wind-wheel, consisting of the radial arms D D, secured in cast boxes (2 at the hub and connected at their outer ends by a ring or circle, d, and by a second ring, d at a suitable distance from the center, in this case about one-third. ,Between these two rings are pivoted the fan-blades D. These blades are formed of sheet metal, as shown in Fig. 3, and are strengthened by a metal rod, d around their edges. They are pivoted in the rings (1 d one-third of their width from the inner edge, thus enabling them to be easily turned without regard to the strength of the wind, and causing the wind when very strong to turn them automatically. They are all connected midway between the rings d d by a third ring, (1*, by which they are all controlled and moved at once.
Upon the shaft 0, between the wheel and the tower, is arranged a loose sleeve, E, formed with an annular groove, 6, provided with a collar, E, having arms 6 extending forward and jointed to cranks 6 upon the inner ends of rods E journaled on two of the arms D of the wheel, and having their outer ends cranked and secured to the ring (1*. A U-shaped link, F, connects the sleeve or collar E with the shorter ends of a yoke-lever, F, fulcrumed on the turn-table and provided with a weight, F upon its longer arm, which tends always to keep the collar at the inner end of its stroke and holds the blades in proper position to catch the most wind, while at the same time any excess of pressure by a strong breeze will turn the blades and overcome the action of the weight. The short ends of the yoke-lever F are also connected by links or rods ff with a sliding collar, G, adapted to slide vertically upon the tube 9, through which the operatingrod 0 passes, and on this collar is pivoted at y, a yokelever, H, having one arm fulcrumed on the tower-frame w and the other provided with a cord, h, leading to the ground. It will thus be seen that any person below may at any time control the speed of the wheel by pulling on this cord,which, by its intermediate connections, turns the fan-blades, and the wheel may be stopped altogether by the same means. The outer end of the shaft C is provided with afour-bladed vane, I, arranged as shown, and these,being opposite the open center of the wheel, catch more of the wind, and are thus smaller and closer to the wheel than is usual. I
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a windmill, the combination of the pivoted blades, the movable ring (1*, cranked arm E connected at one end to the iron ring (1* and at the other with a'yoke capable of movement on the main shaft, and means, substantially as described, for moving said yoke, substantially as shown and set forth.
2. A windmill consisting, essentially, of the tower A,'turn-table A B, shaft 0, connected arranged to operate substantially as and for 10 to the pitnian G, and wheel having radial the purpose set forth. 7
arms D, rings d 0?, and pivoted sheetmetal In testimony whereof Iaffix my signature in blades D, connected by a ring, (1", in combipresence of two witnesses.
