ALBERT G. FIELD, OF QUINCY, ILLINOIS` IIVIPROVED `SELF-REGULATING WINDIVllLL.

To all whom it may concern:

Be it known that I, ALBERT G. FIELD, of Quincy, in the county of Adams and State of Illinois, have invented a new and Improved Self-Regulating Horizontal Windmill; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a side view of myimprovement, the framing being bisected vertically through its center. Fig. is a plan or top view of t-he same.

Similar letters of reference indicate corresponding parts in the two figures.

The nature of my invention consists in a peculiar manner of hanging the wings or sails, as will be presently shown and described, and having weights connected with the arbors or spindles of the wings or sails, whereby the windmill is rendered self-acting, and also prevented from being reacted upon by the wind.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a framing constructed in any proper manner to support a vertical shaft B, which is allowed to turn freely in it. The u pper part of the shaft B extends upward some distance above the top of the framing A and has a hub C attached to it,to which hub radial arms D are connected,four or more arms being` employed. The arms D are braced by rods a, which extend from the upper end of the shaft B to about the centers of the arms.

To the outer end of each arm D there is attached a vertical frame E. These frames extend about an equal distance above and below the arms D, as plainly shown in Fig. l.

In each frame E there is placed an arbor or spindle F, to which the wings or sails G G are attached, there being two wings or sails on each arbor or spindle, one above and the other below the arms. The sails G G are attached to the arbors or spindles out of center, so that five-sevenths of thesails will be on one side and twosevenths on the other side of the arbors or spindles.

Each arbor or spindle has a crank b on it just above the arms D, and the cranks B have cords c attached to them, said cords passing through loops or eyes d, attachedto arms II,which project obliquely from the arms D, and also through loops or eyes c, attached to the under side of the hub C on the vertical shaft B. The lower ends of the cords c have weights I attached to them, and the weights I have cords f connected to them, said cords f passing up through loops or eyes g on the shaft and then passing downward and connected to a small shaft or rotating pin J, attached to the shaft B. (See Fig. l.) The cords c at points near the cranks b have each abutton h upon them, which buttons prevent the weights I from drawing or acting upon the sails only to a certain extent, as will be hereinafter referred to.

The operation is as follows: Suppose the wind to be in the direction indicated by the arrow, Fig. 2. The proper weight I will keep the sails G0 at an angle of about forty-five degrees with the wind, the button 7L on the cord preventing the weight from drawing or turning said sails square with the wind. The weights I keep all the sails in the same position, as shown at GO-that is,when the several sails reach the same point the weight-s being sufficiently heavy to effect this when the wind is blowing with ordinary velocity. As the sails Gomove around toward the leeward side of the wind-wheel, said sails will preserve their position described till the wind catches against the Windward edge of the sails, and the sails and arbors or spindles will be turned in a reverse position, as shown at Gx,t he sails,how ever, still forming an angle of sixty degrees with the wind. As the sails pass around toward the wind, as shown at GXX, the edges of the sails will only be presented to the wind, as they are not acted upon by the weights I at this point, the buttons h being againstthe loops or eyes d, and as the sails reach the Windward side of the wheel the wind will again act upon them, so as to throw them in the position shown at GXXX. By this mode of hanging the wings or sails they cannotl be rcacted upon bythe wind and no loss of powers sustained by reaction. rlhe weights of course are the exponents of the power of the windwheel, and by turning the shaft or pinJthey may be rais-ed, so as to allow the wind to throw the sailsfarther back and cause them to present a greater surface or area to its action, and by raising them still more they will not act 2. Raising;v the Weights I by means of thc coi-ds f, attached to the weights I, and shaft oi1 pin J, arranged substantially as herein shown and described.
