UNITED STATES THOMAS I IATFILL, OF MOUNT HOPE, KANSAS, ASSIGNOR OF ONE-FOURTH TO F. E. TRAOEY, OF SAME PLACE.

WINDEVHLL.

SPECIFICATION forming part of Letters Patent No. 321,292, dated June 30, 1885.

(No model.)

To aZZ whom, it may concern:

Be it known that I, THOMAS HATEILL, a citizen of the United States, and a resident of Mount Hope, in the county of Sedgwick and State of Kansas, have invented a certain new and useful Improvement in Nindmills; 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 Figure 1 is a side view of my improved windmill. Fig. 2 is a horizontal sectional view ofthesame, showing the wings or vanesin position for operation. Fig. 3 is ahorizontal sectional view showing the wings or vanes thrown out of gear, or with their edges to the wind. Fig. at is a vertical transverse sectional view, taken on the line m m in Fig. 2.

The same letters refer to the same parts in all the figures.

This invention relates to windmills; and it has for its object to provide a device of this class which shall possess superior advantages in point of simplicity, durability, and general efiiciency.

Vith these ends in view the invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Adesignates the frame of my improved windmill, which consists, essentially,of side pieces or uprights, B B, connected by cross-pieces G C, which latter are provided with boxes or bearings for the vertical shaft 0.

My improved windwheel, which is mounted securely upon the shaft 0, is constructed of two circular hub plates or disks, D D, having radial arms E E registering with each other.

G G are the wings or vanes, which consist of rectangular plates pivoted vertically between the upper and lower arms, E, by means of pins or pivots H, at some distance from the outer edges of the said vanes. \VashersI are placed upon the lower pivoting-pins, in order to raise the vanes sufdciently to enable them to turn or swing between the radial arms E of the upper and lower disks.

To the rear edges of the arms E of the lower disk are pivoted latch-bars J J, the inner ends of which rest upon the disk D, while their outer ends extend upwardly, so as to form stops K for the outer short ends of the vanes. The upper and lower disks, D D, are provided with slots L L, registering with the radial arms E, and affording bearings for the verticallysliding lock-bars M, which are connected with the disks by pivoted links N, and the lower ends of which converge toward the central shaft and rest upon a plate, 0, mounted upon a sleeve, P, sliding upon the said shaft.

Q is a suitably-arranged forked lever, by meams of which the sleeve P and plate 0 may be moved in an upward direction upon the shaft G, thereby raising or lifting the lockbars, which, by the action of the pivoted connectinglinks N, are at the same time drawn in an inward direction toward the said shaft.

In operation the vanes rest against the lock-bars M while they are exposed to the full force of the wind and until they have passed the center line in which the wind is blowing, when they will swing on their pivots until their outer ends rest against the latches or stops K, thus bringing the vanes into position to be acted upon by the wind twice in every revolution.

In order to throw the device out of gear it is only necessary to raise or lift the lock-bars by the mechanism described, thereby throwing them out of engagement with the vanes, 85 and causing all of the vanes to turn their edges to the wind, as shown in Fig. 30f the drawings.

then it is desired to start the mill, the lockingbars are brought back into position 0 by lowering the plate 0, when the edges of the vanes will engage with them, and the evervarying course of the wind will catch upon one of them and turn the wheel until each one of the vanes comes into play the same as they 9 5 did before the locking-bars were raised.

The shaft 0 is provided near its lower end with a cam-wheel or disk, R, the upper and lower sides of which engage apair of frictionrollers,S S, suit-ably journaled to a bracket, T, 100

at the upper end of a rod, U, arranged to reciprocate vertically in suitable bearings, and from whence the power of the machine may be conveyed to the machinery to be driven. The bracket T may be hinged at the upper end of the rod U, so as to be readily uncoupled from the cam-wheel when required.

In practice one or more of my improved wind-wheels of the same or of different sizes may be used upon the same shaft. In the drawings hereto annexed two have been shown. By properly modifying the construction of the framing, the device may also be successfully used as a water-wheel.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and ad vantages of this invention will be readily understood.

The general construction is simple and durable, the power derived from it is considerable, and the device is easily and efficiently governed and regulated.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a wind-wheel, the combination, with a suitable frame, of a vertical shaft j ournaled in the same, a pair of disks or hubs having radial arms, beveled latch-bars pivoted to the rear sides of the lower arms and having stops at their outer ends, vanes pivoted between the upper and lower arms by pivoting-pins near the outer edges of said vanes, and lock-bars adapted to form rests for the inner ends of the said vanes when in operative position, substantially as and for the purpose herein set forth.

2. I11 a wind-wheel, the combination of a vertical shaft, a pair of hubs or disks having radial arms, vanes pivoted, as described, between the said arms, latch-bars pivoted to the rear edges of the lower arms, lock-bars arranged to slide vertically in slots in the disks or hubs, and connected with the latter by pivoted links, and mechanism for operating the said lock-bars, substantially as and for the purpose herein set forth.

3. In a wind-wheel, the combination of the central vertical shaft, the disks or hubs having radial arms, the vanes pivoted vertically between the outer ends of the said arms, the pivoted latch-bars, the vertically-sliding lockbars connected with the disks or hubs by pivoted links, and having converging lower ends, a disk mounted upon a sleeve sliding vertically upon the central shaft and supporting the loekbars, and a forked lever adapted to manipulate the said sleeve, substantially as and for the purpose herein set forth.

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

THOMAS HATFILL.
