WIND-MOTOR.
SPECIFICATION forming' part of Letters Patent No. 713,094, dated November 11, 1902.
Application led May 1, 1901.
T0 all whom, it mary con/cern,.-
Be it known that I, HENRY Gnis'r, a subject Bishoprick, Horsham, in the county of Sussex, England, have invented new and useful Improvements in Wind-Motors, of which the following is a specification.
In ordinary wind-motive engines as hitherto generally constructed a considerable portion (often the greater part) of the Wind-pressure is spent against the structure and sails as direct thrust and only a' portion of the force is converted into rotary motion of the sails at right angles to the direction of the Wind. t
Now my invention relates to a novel form of motive apparatus for wind-power so mounted that the vanes on which the wind acts revolve in a horizontal plane around a vertical axis and is designed so that nearly all the force of the wind is spent inturning the apparatus and very little of it passes as dead pressure on -the structure. The vanes, or, as
ed in pairs that during about half of each revwind, and during the other half of the revolution they lie horizontally, with their edges turned toward the Wind.
` The vertical axis, hereinafter referred to as the main shaft,7 maybe tubular and mounted in any convenient manner and carries near its upper extremity a iange or projecting rim or the like, to which are attached a supported in the horizontal position by snspensory stays from the upper part of the main shaft, and these arms are also stayed laterally one to another or otherwise. In
arms to the main shaft or the flange thereon, with joints allowing them to be lowered' into a nearly verticalposition around the shaft to facilitate erection and for other purposes. On each such arm or frame are mounted two horizontal parallel or nearly parallel shafts, hereinafter referred to as wing-shafts, the one in the preferred arrangement extending inward nearly to the center and the otherV shorter and both extending outward beyond serial No. 58h79. (No model.)
the arms and each carrying one of the wings. The members of each pair of Wing-shafts are so connected together, either by the device next indicated or otherwise to produce the same effect, that when either shaft makes part of a revolution on its longitudinal axis the other shaft is compelled to make an equal and like movement but in the opposite direction, and for these purposes I may key onto each wing-shaft a spur-Wheel, the cogs of each pair of which intermesh, so that the two Wing-shaf ts share equally in any rotary movement, but in opposite directions. On each Wing-shaft is xed a Wing which may be made of Ycorrugated galvanized-iron sheeting or other suitable material and is fastened at one end of it to the wing-shaft, the wings of each pair being arranged to lie in opposite directions, so that in the operative position one of them rises upward from its attachment and the other hangs downward, and when the wing-shafts are rotated from this position a quarter-revolution, or thereabout, in the proper direction the two wings lie horizontally face to face.
In the arrangement which I generally adopt and which is particularly adapted for the larger motors I fix at the inner end of each elongated wing-shaft a pulley, chain-wheel, or equivalent arrangement which is connected by a chain or the like or otherwise with the upper end of a vertical connecting rod or tube, hereinafter referred to as the controllingrod,7 which passes down the interior of the main shaft and is connected below to apparatus for producing, controlling, and regulating the pressure which holds the wings up or open against the pressure of the wind. The main shaft is provided with a collar or projecting rim which carries the weight of and supports the same and the under surface of which runs on a fixed step either With or without the intervention of ball or roller bearings. The lower end of the main shaft is tted with a brake-Wheel and with bevelgearing or other gearing for transmitting the rotation as required. The lower end of the controlling-rod extends below and beyond the main shaft and is pressed upward with such force as may be required to hold up the wings against the wind, and for this purpose a spring may be arranged with vadjusting mechanism for regulating its force, or a weight or weighted lever may be used for the same or a combination of both with suitable devices for adjusting the weight and limiting the extent of motion and otherwise controlling and regulating the action of the same. For smaller motors, such as are intended for constant loads-such, for instance, as pumping or the like, and particularly for such as are ixed in a tolera-bly easily accessible position as regards height and otherwise-the controlling apparatus described hereinafter is to be preferred.
rThe invention as rst above described will be best understood by reference tothe accompanying drawings, in which- Figure l is a perspective view of the preferred form of my improved wind -motors with certain parts shown diagrammatically for the sake of clearness. Fig. 2 is a plan of portion of the upper part of the apparatus. Fig. 3 is an elevation of the lower end of Fig. 2 with the wings in positions differing from those in which they are represented in said Fig. 2. Figs. 4 and 5 are central vertical sections of respectively the upper and lower portions of the vertical shaft and other im mediately-adjacent parts. Fig. 6 is a section on the line 6 6 of Fig. 4. Figs. 7 and 8 are horizontal sections taken,respectively, on the lines 7 7 and 8 S of Fig. 5. Fig. 9 is a plan, and Fig. l0 is a side elevation, of the device for adjusting the position of the Wings and determining the limit at which they shall yield under excessive wind-pressure. Fig. 11 is a plan of the upper end of the vertical controlling-rod and chain-connecting disk attached thereto. Figs. l2 and 13 are respectively a plan and an elevation of portions of two different slightly-modified forms of the controlling mechanism.
The same letters of reference are used to indicate like parts throughout the several figures of the drawings.
In carrying my invention into practice' in the manner indicated in the drawings I provide a rigid frame A, which may be of any desired construction and is fitted with bearings a a" for supporting the main shaft B in a vertical position. The shaft B is tubular and vhas secured to it, near its upper extremity, a flange, rim, or collar C, to which are attached a series of radial arms c, supported in a horizontal or substantially horizontal position by suspensory stays c', connected to the outer end of said arms and to a casting or boss b, secured on the upper end of the shaft B. The radial arms c are also stayed laterally by stays, rods, or bars c2, extending from one to another of the said arms, or the arms c may be supported and stayed in any other convenient manner.
On the frame C', constituted by the radial arms c and bars c2, are secured a number of bearings d, in which are revolubly supported a number of horizontal shafts d cl2, hereinafter referred to as wing-shafts. These shafts d d2 are arranged in pairs, the shafts of each pair being parallel or nearly parallel to each other and the shaft cl extending inward to near the vertical shaft B, while the shafts d2 terminate at some distance from the said shaft B, as shown most clearlyl in Fig. 2. The outer ends of all of the wing-shafts d d2 project beyond the frame C', and on each of these outwardly-projecting parts is secured one of the wings D' or D2, which are hereinafter more particularly described.
The members of each pair of wing-shafts d d? are so connected together either by equal spur-gearing d3, as represented in the drawings, or by linkage or otherwise, that when either shaft makes part of a revolution on its longitudinal axis the other shaft is compelled to make an equal movement in the opposite direction.
The wings D D2 may very conveniently be formed of corrugated galvanized sheet-iron, and each is secured to its shaft near one edge of the said wing, so that the wings may turn upon the axes of the shafts d d2 through about one hundred and eighty degrees. In the operative position each wing D extends downward below its shaft d', and each wing D2 extends upward above its shaft d2, the two said Wings being then at an angle of about one hundred and eighty degrees apart, or nearly so. This angle may, however, be adjusted, as hereinafter described, to enable the effective area of the wings to be varied to suit the dierent wind-pressures.
On the inner end of each of the wing-shafts d is secured a chain wheel or pulley d4, to which is attached one end ot' a chain or equivalent iiexible connecting device e, whose other end is connected to a disk or armsf, rigidly secured to the upper end of a vertical rod F, hereinafter referred to as the controllingrod, capable of sliding longitudinally within the main shaft B.
The weight of the main shaft B and its directly-connected parts is supported by the bearing a, between which and the collar C above may be interposed two loose annularlygrooved collars g g and a ring of balls g2, running in the grooves of the said collars g g. On the lower end of the main shaft B, below the bearing a, issecnred a brake-wheel b and a bevel-tooth wheel b2, to the former of which brake-pressure may be applied in any convenient manner and with the latter of which gears a bevel-pinion b3, which, through a shaft b", transmits its rotary motion to any desired mechanism or apparatus.
The lower end of the controlling-rod F extends beyond the lower end of the main shaft B and is pressed upward with such force as may be required to hold the wings D D2 up against the wind, for which purpose an adjustable spring 7L or weight t', or, as shown in the drawings, both of such devices, may be employed. In this arrangement the controlling-rod F has rigidly secured to it a collar f', beneath which are provided a loose collar IOC IIO
wheel l', adjustable on a stationary screw Z2,
fixed to the base of the main frame A.
fm is a forked lever pivoted at m to the main frame A and engaging by its slots m2 wit-h the before-mentioned trunnionsj and having a weight t adjustably secured on its outer end. Beneath this outer end of the lever m I provide a screw-stop n, adjustable by a hand-wheel n in a bracket n2, iiXed to the frame A, so as to enable the lever m by means of such screw adjustment and through the mediumof the weight i to be turned on the pivot m, and consequently the controlling-rod F to be lowered or raised for expanding or more or less collapsing or contracting the Wings Dv D2. The wings D are weighted, so as to tend always to move them into their vertical position, and consequently through the gearing d2 to similarly mov'e the other wings D2. Rubber or other equivalent buders o may be provided, preferably on the lower wings D@ to prevent the members of each pair of Wings D D2 from coming into actual contact and making a clashing noise.
In some cases where, for instance, the load is constant, such as for pumping and thelike, more especially for the smaller sizes of motors, the controlling mechanism may be made simpler by attaching a separate controllingspring to each wing or pair of wings, as shown in Fig. 12, in which the wheel d4 is placed farther from the center and a chain e or other connection therefrom is provided with a spring e, which is connected to some convenient fixed part of the frame C' in such man- I ner that the length of the chain e, and consequently the tension of the spring c', may be easily adjusted.
Instead of controlling the wings D D2 by al spring e', as last described, they may,as shown in Fig. 13, be controlled by a weight e2, adjustably secured on a lever e3, pivoted to the frame C', the said lever being connected by a chain e to a pulley or lever-arm d4, secured on the wing-shaft d', the arrangement being preferably such that the weight e2 presents the greatest resistance to the win gs collapsing under eXcessivewind-pressure when they are fullest expanded and gradually less resistance the more the wings yield or collapse under such pressure. 'lhe movement of the lever e3 is limited by astop e4, secured on the frame C.
The arrangements shown in Figs. 17`and 18 render it unnecessary for the main vertical shaft Bto be hollow, and in these forms I- prefer to make the said shaft solid, and I provide greater brake power than is necessary in the first-described arrangement in order to stop the motor when required.-
The wings D' D2 are preferably of such shape that their outer edges form portions of' circles described from a center situate in the axis of themain shaft B and as near as possible in the plane of their surfaces, so thatin whatever position they may be the curve of their outer edges will substantially be included in or form part of the same sphere or figure ofvrotation; otherwise the wings D D2 may be of the general shape indicated in Figs. 1 and 2,
It will be understood from the foregoing description that when the wind, acting in a direction perpendicular to the plane of Fig. 1 and from the observer toward that gure on one side of the vertically-supported wings D' D2, drives the apparatus around, the wings, as soon as each pair reach the point at which the wind commences to blow on the other side or back of them, yield to the pressure of the wind and cause a partial rotation of their respective wing-shafts d' d2 in such wise that the wings lie fiat face to face, as shown at the left-hand side of Fig. 1, and in this movement they are not restrained by the connection of the wing-shafts d d2 with the controlling mechanism, because the rotation of the wing-shaftsd d2 in that direction only slackens the chains e or produces the like effect. As soon as the closed pairs of wings reach the point at which the wind again blows on the other side of them-that is to say, against and between their free edgesthe wings separate and reassume their open or vertical position. When in this position, they are prevented from yielding and turning farther over by the action of vthe controlling mechanism so long as the force of the wind does not'eX- ceed the power required for the load on the motor or, in other words, that for which the said controlling mechanism has been previously adjusted; but when this is exceeded the wings D D2yield and turn backward, rotating their wing-shafts d d2 against the pressure of the controlling mechanism until the wings assume an oblique or nearly horizontal position, in which the wind glances off them with very little resistance, thus relieving` the structure from excessive strain in boisterous or stormy weather, and thus maintaining a fairly regular speed.
With the mechanism shown in Figs. 1 to 11 the motor may be rendered inoperative when desired by lowering the nut or handwheel Z/ to its lowest position and raising the screw-nut n, so as to remove all resistanceto the collapsing of the wings.
By the use of the mechanism hereinbefore described I am enable to employ for an apparatus yielding a given power a much lighter supporting structure in proportion to the power developed than has hitherto been practicable.

As tubular shafting such as that of which the main shaft B should be constructed is expensive and not readily obtainable, I may with Very considerable advantage construct the said main shaft of wrought-iron pipe, such as that ordinarily employed in gas and water supply installations, this being used in single or multiple thicknesses, according to the power to be transmitted.
For readily and efficiently coupling together the ends of these pipes, which are not usuallylong enough to in one piece form the complete shaft B, I may use a device, such as shown in Figs. 12 to 16, inclusive, comprising a liner or bush p, bored or otherwise formed to constitute a guide for the controlling-rod F and externally of such diameter that it will nicelyT fit into the ends of the two pipes or innermost of the pipes to be connected. In Figs. l2 to 14E I have represented the shaft to be made up of two concentric pipes q q; but it will readily be understood that any other desired number may be similarly combined. The end of each pipe which is to be coupled to its neighbor is formed with diametrically opposite recesses r, adapted to engage with feathers or keys p, formed on the exterior of and integral with the liner or bush p, the depth of the said recesses being approximately about one-half the width (incasured longitudinally of the bush) of the feathers or key p. Each of the concentric pipes q q' is similarly fitted to the feat-hers or keys p', which latter extend radially outward beyond the outer surface of the outermost of the said pipes-viz., q-so that its outer ends may engage with recesses s, formed in the inner surface of a split or divided clamp or band s'. This clamp or band s may be rigidly secured about the pipe-joint, and the coupling thereby made complete by screwing the two portions of the said clamp together by bolts or nuts s2, the feathers or keys p by engaging with the recesses s preventing any longitudinal displacement of the clamp on the pipes. Any difliculty which may be experienced as regards the looseness of lit of one pipe within another may be readily overcome by means of a tube-expander or equivalent device applied to merely the ends of the said pipes, so that the whole construction of the shaft is one which may be readily carried out.
