SPECIFICATION forming part of Letters Patent No. 374,904. dated December 13, 1887.

Applicaiion filed November i3, 1886. Serial No. 218,769. (No model.)

To all whom, t may cgnc'c'n:

Be it known that I, HENRY MYERS, of Garnett, inthe county of Anderson and State of Kansas, have invented certain new and useful In'iprovements in Windmills; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figui-e1 isa perspective view ofmy improved windmill. Fig. 2 is a vertical sectional view of the same, and Fig. 3 is a horizontal sectional view.

Similar numerals of reference indicate corresponding parts in all the figures.

My invention has relation to that class of windmills which revolve in a horizontal plane,

land have vanes hinged at their inner edges and claimed.4

and placed obliqnely to the face of the frame to which they are hinged, having means for adjusting their angles to the direction of the wind; and it consists in the improved construction .and combination of parts of such a windmill, as hereinafter more fully described In the accompanying drawings, the numeral 1 indicates the vertical post of the frame, which is formed at its upper end with a vertical bearing, 2, in which the vertical shaft is jonrnaled, the said shaft having its lower end journaled or stepped in a suitable bearing or step, 4.

The shaft is formed near its upper end with a disk or spider, 5, from which projects a conical frame consisting of downwardly and outwardly inclined arms 7, connected by means of bars 8, in which slats 9 are secured in radiating planes. The lower ends of the inclined arms are connected by a circular rod, 10, and the vanes 11, which increase in width toward their lower ends, are hinged with their inner edges upon the outer sides of these arms, at the rear edges of the same, folding into the spaces between the arms, covering the outer edges of the radiating slats. All the arms, or a number of the same, have rods 12 secured to their outer sides by means of staples 13, and the upper ends of these rods are secured to the upper end of the vertical shaft, while the lower ends are provided with nuts 14, which bear against the under sides of eyes 15 at the lower ends of the arms, the said rods serving to brace'the conical frame,having the nuts for the purpose of drawing the frame upward if it should sink upon the shaft. A collar, 1t', slides upon the shaft below the spider of the conical frame, and is provided with a circum- 6o ferential groove, 17, and with an annular iiange, 18, at its lower end. Arms 19 are pivoted with their inner ends in eyes 20 in the periphery of this flange, and the outer ends of these arms project through spaces between the radiating slats and are pivoted to the inner sides of the vanes, having their outer ends inclined downward. A forked yoke, 2l, projects from a bar or rod, 22, sliding in vertical bearings upon the side of the upright post, 7o and this yoke tits with its arms into the groove in the sleeve, so that the sleeve may revolve within the arms of the yoke, and the sleeve at the same time may be raised or lowered by the rod and yoke. The lower end o f the sliding rod is pivoted to the upper end of a connecting-rod, 23, the lower end of which is pivoted to the short arm of a lever, 24, pivoted upon the side of the upright post, and

the long arm of this lever has a weight or 8e poise, 25, adjustably sliding upon it.

Long arms 26 project from the flange of the collar, projecting downward and outward through longitudinal slots 27 in two dia- Y metrically-opposite arms of the frame, and the lower ends of these arms or rods are bifurcated and formed with a series of trans verse perforations, 28, through which pass bolts 29, by means of which the'ends of the rods are pivoted to the ends of two bell-crank 9o levers, 30, fulcrumed at their bends upon the lower ends of the arms and having weights 3l upon their lower ends. v

It will now beseen that when the wind blows against the mill the wind will blow into the inner sides of the vanes, which will be forced to stand obliquely ont by the weights upon the bell-crank arms, allowing the wind to revolve the wheel, and when the wheel revolves the weights upon the-said bell-crank arms will be roo forced ont by the centrifugal force, throwing the arms out and forcing the rods pivoted to their upper arms upward, raising the collar, which will cause the collar to draw upward upon the rods pivoted to it and fold the vanes against the edges of the radiating slats, oiering less surface for the wind to act against. As the wheel slacks in speed, the weights will drop, drawing the collar down and pushing the outer edges of the vanes outward, again offering more surface to the wind, the said balls acting as governors for the speed' of the wheel.

The adjustably-sliding weight upon the lever will serve for the purpose of regulating the force with which it is necessary to slide the collar, and thus serve to regulate the speed of the revolutions of the wheel, the weight being adjusted farther out upon the lever-arm for the purpose of increasing the resistance to folding the vanes, while for the purpose of decreasing the resistance against the folding of the vanes the weight may be adjusted nearer the fulcrum, the weight being raised as the vanes are folded.

By having the vanes decreasing in width toward their lower ends, and by having the frame wider at its lower portion than at its top, the force of the wind upon the wheel Will be greater at its lower portion than at its top, preventing a too great pressure at the top of the shaft from breaking the shaft or from tilting the frame and shaft, which may happen in wheels of this class, in which the Vpressure of the wind at the top of the wheel will be as great or greater than the force at the lower end of the wheel.

The wheel may be stopped by drawing down upon the lever having the adjustable weight, which will push the collar upward upon ythe shaft and close the vanes into the spaces having the slats, giving the wheel a smooth conical surface.

The wind passing against theinclined inner faces of the vanes will be forced inward and against the radiating slats, causing the wind to exert its force against the slats, assisting in revolving the wheel, although the slats may be dispensed with, if desired.

The entire wheel may be constructed at a comparatively low cost, as it contains but few and simple elements, and will be very strong and durable on account of its simplicity and on account of its shape, and it will require no attention while in operation, as the governors will adjust the vanes in accordance with the force of the wind, it being only necessaryyto once adjust the weight upon the lever to be raised at a certain pressure, when the vanes will be folded whenever the wind increases to such a pressure and again be folded out when the pressure decreases.

The shaft may extend to the bottom of the tower or supporting-'frame of the mill, or it may stop near the upper end of the same, and it may be provided with any suitable means for conveying the rotary motion to the foot of the tower or frame and with any suitable means and mechanism for converting the rotary motion of the shaft into reciprocating or other motion or for conveying the motion to a distant spot, the wheel being, however, principally intended for the purpose of pumping, and being then suitably connected to a reci procating pump-rod.

Having thus described myinvent-ioml claim and desire to secure by Let-ters Patent of the United States- 1. In a wind-wheel, the combination of a vertical shaft having a conical frame formed by downwardly and outwardly inclined arms, vanes having their lower ends wider than the upper ends and having their inner edges hinged to the rear edges of the arms, a collar sliding upon the shaft and having an annular ange, downwardly-diverging rods pivoted to the fiange and to the vanes, rods pivoted to the flange and projecting through slots in the arms, and bell-cranks pivoted upon the lower ends of the arms and vhaving their upper arms pivoted to the rods projecting through the slots and having weights upon their lower arms, as and for the purpose shown and set forth.

In a wind-wheel, the combination of a vertical shaft having a conical frame formed by downwardly and outwardly inclined arms, vanes having their lower ends wider than their upper ends and having their inner edges hinged to the rear edges of the arms, a collar sliding upon the shaft and having a circumferential groove and an annular flange at its upper end, rods pivoted to the said flange andv to the inner sides of the vanes,diverging with their lower ends, a rod sliding in bearings parallel to the shaft and havinga forked yoke engaging the groove in the collar, and a lever pivoted at the lower end of the shaft and having an adjustable sliding weight upon its long arm `and having a connecting-rod pivoted to its short arm and to the lower end of the vertically-sliding rod, as and for the purpose shown and set forth.

8. In a wind-wheel, the combination of a vertical shaft having a conical frame formed by downwardly and outwardly projecting arms, vanes hinged with their inner edges to the rear edges of the arms, a collar sliding upon the shaft and having a flange at its upper end and a circumferential groove, rods diverging downward and pivoted to the flange and to the inner faces of the vanes, rods projecting through slots in the arms from the fiange of the collar, bell-cranks fulcrumed upon the lower ends of the arms and having their upper arms pivoted to the rods projecting through the slots and having weights upon their lower arms, a vertically-sliding rod parallel to the shaft, having a yoke engaging the groove of the collar, a lever having a sliding and adjustable weight upon one arm, and a eonnectingrod pivoted to the lower end of the verticallysliding rod and to the shorter arm of the lever, as and for the purpose shown and set forth. l v

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses. l
