WIND-WHEEL.

SPECIFICATION forming ypart of Letters Patent No. 5 2 3,842, dated July 31, 1894.

l Y Application led October 31, 1893. Serial No. 489,669. (No model.)

To a/ZZ whom it may concern.: .Be it known that I, LAVERNE W. NOYES, citizen of the United States, residing at Chicago, county of Oookan d State of Illinois, have Vinvented certain new and useful Improven1ents in Wind-Wheels, which are fully set forth in the followingl specification, reference being had to the accompanying draw ings, forming a part thereof.

The purpose of this invention is to provide a wind-wheel of superior rigidity and lightness. It consists in features and details of construction which are setforth in the claims.

Figure 1 is a face view of a portion of the wind-wheel embodying my invention. Fig. 2 is a detail section looking toward the center at the curved line 2 2 on Fig. l. Fig. 3 is a detail section at the curved line 3-3 on Fig. 1,looking toward the center. Fig. 4 is a sectional detail at the line 4 4 on Fig. 3. Fig. 5 is a perspective of a cross-bar which connects the tangent spokes at the inner supporting ring or band. Fig. 6 is a side elevation of the hub of the wheel. Fig. 7 is a detail face elevation of one of the spoke-holding lugs on the hub. Fig. 8 is a detail elevation of part of one sail of slightly moditied form. l

The general character of the wheel to which my invention. is applied is what is known as a solid wheel, or one in which the vanes or sails are fixed imposition relatively to the plane of the Wheel. More specifically, it is a wheel in which the sails are secured to two rings or bands, which are themselves held concentric in relation to the hub and shaft' sails to the framework, and specifically, to-

the rings or bands mentioned, and for rendering the sails rigid in the transverse form which may be given them to render them most effective in gathering the force of the wind.

outer ring or band for the purpose of rendering the wheel as rigid as possible in resistance to the wind blowing throughit. -Each of the flanges or disks A A2 has a plurality of radially projecting lugs for the purpose of attaching the spokes, hereinafter described. As illustrated, each flange is provided with three of these spoke-holding lugs, the lugs A10 A10 A10 on the flange A being similar in form to the lugs A20 A20 upon the iiange A2, and alternating with them in circumferential position, as seen in Fig. 1, wherein the six llugs appear projected upon one circle in the view, the lugs A10 and A20 alternating at equal intervals throughout the circle.

D D D D, &c., are spokes which are formed in pairs, the two members of each pair being of one piece of wire or rod bent at the middle point, and the two branches spread as seen in Fig. l. These bent lrods are hooked onto the T -shaped lugs A10 A20 in the mannerillustrated, so that the bend engages around the stem or post @100.20 of the lug, the two branches extending out nonradially with respect to the wheel behind or under the branches a11 a21 of the cross of the T, the form of both the stem and cross being made to afford snug seats for the rodin itsgcourse, that is, the stem being curved to fit the Acurve of the bend in the rod, as seen at c, and a shoulder c being formed at the base of the stem to hold the bend of the rod close up to the stem, and the arms of the cross having concave seats 0.11 d10 on the inner side, as seen in Fig. 5,. The form of the lugs having the stem projecting radially from the periphery of the body of the hub and the cross on the end ot' the stem, adapts the hub with such lug to be cast in a simple manner without cores for the purpose of forming the lug; Y and the construction which provides the seat for the bend of the rod on the outer side of the stem, so that the vtwo branches extending from the bend make a return to pass behind the cross-bar of the lOO , positely and` equally from true radial direc- T, makes the lodgment of the double spoke of the lug very secure.

The proximate arms of the pairs of spokes which are consecutive in the circumference of the wheel,-counting those at both ends of the hub in one series or circle,-diverge option, and converging toward a radial plane midway between them, pass each other, and in face view of the wheel appear to intersect at such radial plane. But the spokes lean toward each other from the opposite ends of the hub, and their outer ends are located in the saine circle; at the point of apparent intersection, therefore, they are separated from each other,-measuring along a line parallel with the aXis,-a distance proportionate to the distance of that point from the center of the wheel. The ends are all secured to the outer band or ring C, and theinner band or ring B is located at the circle containing the points of apparent intersection of the proximate spokes. As stated, the outer ends, being all in one circle, all penetrate and are directly secured at the outer ring C. The inner ring B stands between the two sets of spokes which lean toward each other from the opposite ends of the hub, as stated, and at the points where the adjacent spokes pass, and inface view seem to intersect, there are secured to this inner band or ring, cross-barsE E E E, dsc., through which, ou opposite sides of the'band B, the spokes of the two sets are inserted at d d.

As a matter of convenience in construction, both the rings B and C are made in several pieces or arcs which lap and are secured together at theirproximate ends; and it is convenient to make the points of lapping also the points at which the cross-bars E are secured and the spokes pass, and in the drawings the structure is so illustrated; but this is not material to the present invention, except that the same bolt E', which secures the crossbar Eiserves also to secure together the lapping ends of the portions of the inner band B, and that the ends of the spokes themselves, being shouldered at d', and threaded beyond the shoulder, serve the purpose of bolts to secure the lapping ends of the several sections of the outer band C. For the purpose of `rendering the cross-bar E rigid in their cross The cross-bar being then riveted to thebandl between these shoulders is preventedfrom turning from its cross-wise position except under strain sufficient to crush or distort the shoulders.

Preferably, as being the lightest construction consistent with necessary stiffness, these cross-bars are made of channeliron, and the shoulders e e are made by striking up the metal from the web of the channel-bar which is severed on three sides of the tongue thus formed,as seen distinctlyin Fig. 5.

By means of this construction, the framework of the wheel comprising the hub, spokes and bands, is made very rigid proportionately to its weight, with very few fastenings by rivets or bolts, the spokes being secured to the hub Without any devices of that nature, and the spokes serving to unite the dii-ferent sections of the outer bands in lieu of additional bolts.

The wheel is rendered very stiff as to pressure against its face or in the direction of the axis, because of the wide spread at the hub of the spokes `which converge to the same midway plane at the outerband; and by reason of the spreading of each pair of spokes which are formed in one piece to cause each spoke to diverge from true radial direction, the spokes ail become what are commonly known as tangent spokes, half being tangent in one direction and half in the other direction to the small circle X ou Fig. l with the usual advantage of tangent spoke construction.

The other feature of improvement in this wheel relates to the sail or vane and its mode of attachment to theframework.

F F F are the sails which are made of sheet metal, tapered longitudinally and Icurved transversely, as seen in Figs. 1` and 2, respectively. These sails areset at an angle to the plane of the bands, as seen clearly in Fig. 2, and have the aperture f, through which the band C passes. The inner narrower end is secured to the band B by a smallangle clip G, as seen in Fig. 3.

H is a rib of sheet steel the form `being clearly seen in Fig. 2, having one 'edge concave to conform `to the transverse form of the sail, and having at the ends lugs H l-I, which are notched in the arc of the curved edge to receive the edges of the sails, as also seen, in Fig. 2. At the middle of the curvededge, there is formed the lug H2, bent at right angles to the plane of the rib I-I, the Width of this lug being substantially the thickness of the band C, and its length or extent in the direction of the concave edge being substantially the Width of the aperture f,\madein the sail for the band C. The rib is applied to the sail at the narrower end, andslid up on the vane, the edges of the latter entering the notches in the lugs I-I, and when the lug H2 reaches the openingf, it snaps into it, the sail having been sprung slightly from its normal curvature by thus passing the rib up into it, because the lug H is set oit from the arc of the curved edge 71J of the riba distance equal IIO IZO

i i w Agaged with the margin ofthe aperture, leaves that aperture open below the sail for the band C, which, being inserted, serves as a key to hold the'rib in its place inthe sail. The latter is thereby stilfened, being grasped by the rib at the edges where the lugs H of the rib clasp it, and at the middle where the lug H2 clasps it through the openingf. The rib itself is forced into a curve conformed tothat of the band B by the edges of the sail stopping in the notches in the lugs I-l, before the lug H2 reaches the aperture f, so that the rib has to be sprung up or outward from the wheel center at the middle part to cause'the lug to reach and enter that aperture. If this were not done, and if, on the contrary, the rib were allowed to remain straight, it would stand in the direction of a chord of or tan gent to the circle in which it would revolve with the wheel, and would very seriously retard the wheel and decrease'its power. A modification of the form of the sail to more certainly canse the rib to be thus curved when it is pnt into place is shown in Fig. 7, shoulders F being formed on the lateral edges of the sails toV positively stop the rib at both ends at the proper points instead of relying upon the exactness of the fit of the sail between the notches in the lugs H of the ri-b and upon the care of the workman in assembling the parts with the necessary precision.

tening of the sail to the band C, for it has the triangular projection H extending beyond the line of its general 'crescent form, one edge of the triangular lug being directly cross-wise of the band, and the other edge parallel with the latter and folded down along its edge, as seen at H31 in Fig. 2 one bolt h', through the rib at its widest part, exclusive of the triangular lug, co-operating with the flange H31, makes the rib rigid with the band C, and so secures the sail firmly.
