WIND-ENGINE.

SPECIFICATION forming part of Letters Patent No. 457,273, dated August 4, 1891.

Application led December 3, 1890. Serial No. 373,493. (No model.)

.To @ZZ whom t may concern:

Be it known that I, DANIEL HALL, a Citizen of theUnited States, and a resident of New York, in the county of New York and State I vely, as they are presented to or against the wind, and at the same time causing them to maintain a position at right angles to the d1- rection of the wind during. their entire passage around their primary center of revolu-y tion-to wit, the center of the vertical rotary spindle-and also at the same time around their secondary center-to wit, that point in the radial arm of the vertical rotary spindle at which the sail-shaft is mounted-the whole .invention being fully illustrated and described in the accompanying drawings.

Figure I represents a horizontal section of a wind-engine embodying my invention. Flg. II represents a side view thereof, partly 1n section. Fig. III represents a cross-section on the line a: 0:, Fig. I. Fig. IV represents a like section on the line y y, Fig. I.

Similar letters of reference indicate similar arts.

p The letter A indicates the main shaft or spindle carrying the radial arms B in any desired number, preferably not less than three, and said arms duplicated in rows perpendicularly one below the other to any desired number of rows, preferably not less than two, at any point in those arms, preferably near their outer extremities and equidistant from thelr common center. Boxes B are mounted,con structed, and adapted to receive and carry a perpendicular or vertical journaled shaft C, which is to be mounted there, and which may be denominated a secondary or sail shaft. From the sail-shaft at points equidist/ant from and preferably near to its j ournaled bearings are constructed arms D at right angles to the perpendicular shaft. These arms are both dual and bifurcated and terminate at an equal length or distance from the shaft that carries them and each several pairs of ends connected vertically by a rigid rod-D. -Sails C', composed, preferably, of some material lof great prehensile power in proportion to its weight, thickness, and superficial area and with pivotal spines running longitudinally near or through their centers, are mounted in sections by means of those pivots placed in bearings horizontally and vertically one above the other on the rods D', connecting the ends of the bifurcated arms D of the sail-shaft C, or the sail-shaft C, instead of being jonrnaled and mounted in boxes, as set forth, may be constructed hollow through its center from end to end like apipe or sleeve and mounted at the same point on the radial arms B occupied by the boxes B by means of a pivot-center running through the sleeve and firmly secured in aforesaid radial arms. Also, in like manner, the primary vertical spindle,

instead of being rotary, may be made stationary, in which case it will act as a pivot, and the radial arms attached to a sleeve will revolve around it, the one construction being the equivalent of the other, amounting simply to a change of journaled bearings. Each of the pivotal spines of the sails C'is provided with a crankarm C, which stands at an upward angle of forty-five degrees from the sailspine when the sail is vert-ical, and-the eX- tremities of each of these crank-arms is pivoted to a vertical connecting-rod f, having its lower end curved and provided with an anti-f friction. roller at its lower end adapted'to ascend the incline D of the lower radial arm with the effect of shifting the sails from a horizontal to a vertical position.

At the point on the lower one of the arms B cut by the circle and in the radius of the circle' described from the center of the sailshaft C by the lower end of rod f is securely attached a permanent inclined plane to engage the anti-friction roller at the base of the rod f on its approaching a fixed point in its rotary passage, to wit-as it approaches that point from which the wind is blowingfor the purpose and with the effect of shifting the sails from a horizontal to a Vertical position.

IOO

Immediately in front and at mid-length of the bottom of the lower section of the sail C is,

Vis supported by a bearing on the sail-shaft C.

From Vthe outer end of the rock-shaft E and vertically beneath it hangs the crank-shaft F with the anti-friction roller F.

On the lower radial arm B and atthe point `on'i't cut by the circle described from the center of the sailshaft C at the distance measured by the shorter end of the rock-shaft E and in its radius I place the lesser incline F2 to engage the anti-friction roller at a given point in its rotary passage around the primary center in the Vertical spindle A-viz., a point near that to which the wind is blowing-causingtherock-shaft E to perform onequarter of a revolution, and thereby throwing the spring-stop into a horizontal position,with the effect of releasing the sail from its vertical and allowing it to assume a horizontal position.

A permanent stop E2, as shown in Fig. II, is placed on the rigid rod D to hold the sail in a horizontal line when against the wind or when the engine is stopped.

To stop the engine, it is simply necessary to keep the sails in a horizontal position, and I elfect this by preventing the spring-stop E from engaging them when presented to the wind. This I accomplish by suspending the rock-shaft G in bearings underneath the ra- -dial arms B, with thev incline G attached to its eccentric extremity beyond the end of the arm B and in the radial path of the anti-friction roller F as it approaches the point from which the wind is blowing and the crank-arm F3 on the other end near the vertical rotary spindle in such position that when the crank` F3 is drawnfto a vertical position by means of the hand-rod H the rock-shaft G will make one-fourth of a revolution, causing its incline G on its eccentric end to rise up in the path of the roller F', causing it to turn the rockshaft E, so that its yielding stop will be horizontal instead of vertical and allowing the sail to resume a horizontal position.

To start the engine, it is simply necessary to release the hand-rods II, allowing the rockshaft G to revolve,when the weight of the ineline G on the eccentric end of its rock-shaft will cause it to descend out of the path of the anti-friction roller F. The engine being then moved forward in the direction of the arrows, as the sail reaches the direction from which the wind is blowing it will assume and maintain a vertical position till it arrives at a point to which the wind is blowing by the automatic action of the devices, as set forth, and for the purposes set forth.

What I claim as new, and desire to secure 7o by Letters Patent, is-

l.
