WIND-WHEEL.

SPECIFICATION forming part of Letters Patent No. 255,432, dated March 28, 1882.

yApplication iiled February 16, 1881. (Model.)

. lowing is a specification.

My invention relates to improvements in wind-wheels in which the sails are pivoted to the inner and outer rims, so that when struck by a violent wind said sails will swing upon their pivots and present their edges to the wind.

The object of my invention is to provide means for relieving the -pivot of the sails from strain, to prevent the sails from oscillating too freely when swung around, as well as to stay them when swung in the wind, and to afford means f'or simultaneously swinging such sails into a subsiding violent Wind. I attain these objects by devices illustrated in the accompanying drawings, in which- Figure l represents a detail front elevation ofa wind-wheel embodying my invention; Fig. 2, a similar elevation of the same in its operative position with the sails edge to andout of the wind; and Fig. 3, a side elevation of a wind-wheel embodying my invention and`sh0w' ing its connection with tower and tail-vane; Fig'. 4, a detail showing the manner of pivoting the sail to the inner and outer rims and auxiliary rims, and also the location of one of the springs used to automatically swing the sails upon their pivots into a decreasing wind;

Fig. 5, a detached section, showing the stationary and auxiliary rims, one of the sails, and the manner of pivoting and automatically operating same by means of the .springf Similar letters of reference indicate the same parts in the several gures of the drawings.

A represents the cap ot' a windmill-tower supporting a bracket, a,tailvane B, and forming a bearing for the crank-shaft C, carrying upon its outer end the hub c and operating the vertical shaft c', all of said parts being of the usual construction. Hub c carries the usual number of spokes d, which support the inner and outer rims, ce', respectively, between which sails F, having angular or turned-up inner edges, f, are pivoted, as clearly shown in Fig. 4 of the drawings, by rods g, secured tothe their bearings in auxiliary' inner and outer rims,t' t', respectively, which have no other 6o support, except said rods or the ends of the sails, as the case may be.

By pivoting the sails as above described I have provided an expansible rimpaording a firm supportand stay for the sails, without in- 6 5 terfering with their free pivotal movement, and at the same time serving to prevent the sails from oscillating upon their pivots, and, moreover, staying them against collapsing when struck by a violent and sudden gust of 7o wind. By an expansible rim77 I mean a rim having the function of. spreading itself apart laterally when the sailsyswing out of the wind.

In order to cause the sails to automatically swing into the wind, one or more coil-springs, k, are secured upon the spokes of the wheel and provided with a straight arm, k', engaging with the ends l of the pivot-rods h, projecting upon the inside of the inner rim, fi, or with studs upon the inner side of said rim, so as to 8o press theauxiliary rims'toward the rims proper, and thus swing the sails upon their pivots.

It is obvious, however, that any other farm of spring adapted for this purpose might be used without departing from the spirit of my invention-as, for instance, a contracting spiral spring connected at each end to the rims. y

For the successful operation of a wind-wheel it is necessary that it should not at all times come to or remain at a standstill when sub- 9o jected to the pressure of a violent wind, and to obviate such an objection I have provided the sails with the angular edges f, for it will be understood that even though the outer edges of the sails be turned direct toward the wind these flanges will be always slightly in the wind, and hence the wind-wheel be kept in motion. Furthermore, by having such angular flanges the sails will hold more wind when full or at au obligue angle to the wind than if their Ioo faces were perfectly plain.

It will be seen that by having double rims which operate to stay the sails, as before dcscribed, the strain upon the sails is distributed iu such a manner that I may make the rims so light that their combined weight may be much less than when a single or solid double rim is employed-that is, a rim ofextra Width, now in use-and therebyI can have a lighter wheel of the same strength and durability.

Haviu g thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a wind-wheel, the combination, with pivoted sails and with the ordinary wheelrims, of an auxiliary inner and outer rim supported by said sails, as and for the purpose set forth.

2. In a wind-wheel7 the combination, with the ordinary Wheel-rims and with the pivoted sails, ofthe auxiliary Outer rim and inner rim,

with the springs for operating said auxiliary rims to automatically swing the sails into the Wind.

3. The combination, withthe stationary inner rim and outer rim, and with the movable inner rim and outer rim, of a series of sails provided with angular flanges and pivoted to said stationary and movable rims.

4. In a wind-Wheel, the combination, with the hub, the spokes, the stationary inner rim, and outer rim secured to said spokes, of the movable rims 'i and i', the sails F, pivoted as shown, and a spring connecting the spokes with the pivot 7L or with the rim z'.
