SPECIFICATION forming part of Letters Ifatent No. 534,167, dated February 12,1 895.

Application led .Tune '7,1894- Serial No. 5131806- (NO 11105010 A Y To @ZZ whom t may concern:

Be it known that I, FREDRIOK A. MATHEWs, a citizen of the United States, residing at La Harpe, in the county of Allen and State of Kansas, have invented a new and useful Windmill, of which the following is a specistruction and combination and arrangement of parts'which will be the' more fullyvv den scribedand finally embodied in the claims.

In the accompanying drawings: Figure l represents a side elevation of my invention; Fig. 2, a plan view; Fig. 3, a bottom plan of the platform; Fig. 4, a vertical section; Fig. 5, a detail perspective of one of the windblades, showing it attached to the hub of the wheel; Fig. 6, a detail perspective showing the construction of the platform; Fig. 7, a detail perspective showing the devices for attaching the adjustable vane.

The reference numeral 1 indicates the framework of the tower, which may, of course, be of anypconstruction. The upper ends of the vertical standards of the frame 1 are rigidly secured to the downwardly-projecting studs 2, of the circ-ular plate or disk 3. This disk 3 is disposed horizontally and provided with a central orifice th rough which the barrel 4 passes, while itis strengthened by the ring 5, arranged on its upper side and embracing the barrel. Formed in the ring 5 and disk 3, and vertically aligned in each, are the openings 6, in which the wedge-key 7 is arranged 1 and by which the barrel is to the disk and ring. y

The barrel 4 is hollow throughout its length and provid/ed at its upperend with a block 8, which is secured rigidly in place and serves to close said end. Formed in the block 8, and axially coincidentwith the barrel, is the passage 9, in which the drive-shaft 10 of the marigidly connected chine is arranged, so as to be capable of ro-v 'Fliese ends are,

extends vertically throughout the length of the barrel and is seated, at its lower end, in the cup-bearing 11, formed in the block 12, the block being arranged, in turn, in the lower end of the barrel and rigidly secured thereto and to the brace 13 of the frame 1.

Formed in the barrel 4, just below the disk 3, is the horizontally-elongated slot 14, which is adapted to furnish access to the small beveled gear 15, fixed to the shaft 10. YThe gear 15 is of a diameter which will make it possible to pass itthrough into the interior of the barrel, and it is by this means that the parts f are placed in position. The gear 15 meshes with therlarge crown gear16, mounted upon the stub-shaft 17, and this is, in turn, iixed'to the lower end of the barrel by screwing it therein, or Y otherwise. By these means the motion and power attending the shaft 10 are trailsmitted to the wheel 16, and from the wheel 16 the power is communicated to the pitman 18, through the medium of the crank-pin 19, fixed lto the wheel, and pivotally connected to the upper end of the pitman. The pin 19 is secured to the wheel16 by means Vof one of the series of openings 20, which are arranged in radial alignment, and by this means the stroke of. the pitman can be made long or short, to

'4, is the platform 25, which is circular in shape and centrally perforated to permit mounting it. Located in the opening inthe platform 25, and rigidlyl secured therein, is the bushing 26, which is formed with a downwardly-eXtending portion 26a and with a rabbet groove 27 on its upper side, in which groove the collar 28 is adapted to lie.

The collar 28 serves to hold the platform 25 in place, and it is itself retained byv means of the key 29, passed'diagonally through it and engaging the block 8. The platform 25 is preferably formed of sheet metal and pro` IOO vided at its periphery with the vertical (lange or wall 30, which extends fora distance equal to little less than one-half that of the periphery of the platform, and is of a height equal to about the radius thereof. Formed at one end of the ange or wall 30, and extending radially therefrom, is the offset or secondary flange 3l, and this is adapted to serve as a vane or guide for the wind, whereby it is 1o guided into engagement with the wind-wheel,

as will be hereinafter described.

Formed in the platform 25, and extending from the olf-set 31 to a point near the center of the platform, is the downwardlyinclined side 32,which has one side extending radially on the platform, while the remaining side eX- tends olf laterally from the rstand at right angles thereto to the periphery of the platform. Rigidly secured to or formed integral V 2o with the periphery of the platform,and extending around the edge of the portion 32, is the wing 33, which curves outwardly and up` wardly and operates, with the olfset 3l, to`

guide the wind up the incline 32 and into enf 5 gagement with the wheel.

The platform is revolubly mounted so that it will ne capable of `adjusting itself to the direction in which the wind is blowing and this adjustment is effected by the vanes 3e 34 and 35, one of which is rigid, while the companion is pivoted so that its angle may be varied for a hereinafter-described purpose. The vane 34 is the rigid vane, and is riveted or otherwise secured to the under side of the 3 5 platform by means of the attached arm 36, which extends downwardly from the platform and is rigidly connected to the vane, whereby the Vane is located below the plane ot' the platform.

The disposition of the vane 34 is approximately radial, and itis located at a peripheral point on the platform, about one-half the distance between the wing 33 and the end of the flange 30, which end is opposite the one having the offset 3l. The vane 35 is arranged at the said end of the iiange 30, and normally projects radially from the platform. The vane is pivoted to the stud 37, xedin turn to the lower side of the platform, by means of 5o the arm 38, rigidlysecured to the Vane at one end and to the disk 39 at the remaining end. The disk 39 is provided with a central opening which embraces the stud 37, whereby it is pivotally mounted, while its movements are limited within the extent of a quadrant by means of the peripheral slot 40, operating with the pin 4l, fixed to the platform.

Rigidly secured to the disk 39, and concentric therewith, is the grooved pulley 42, to

6o which the cable 43 is fixed and over which it operates. The cable 43 is ixedto the pulley 42 by means of the pin 44 and proceeds around one-half of the periphery of the pulley and is connected to the retractile spring 45. The spring 45 is connected at its remaining `end to the spindle 46, which is passed through an opening in the arm 47, depend ing from the platform and screw-threaded throughout its length. Operating on the screw -threaded portion is the nut 48, by which the spindleis held from passing through the opening in the arm 47, and by which the spindle may be adjusted so as to increase or diminish the tension of the spring 45. By these means the pulley 42, and consequently the vane 35, is given a tendency toward the flange 30, the vane being capable of moving against the tendency of the spring and to ward the companion 34. This movement is effected by means of the ptman 49, which is pivoted to thepulley 42, and which extends across the under side of the platform to the short arm of the bent lever 50. The lever 50 is pivoted at itsbendto the arm 5l, rigidly secured, in its turn,;to the platform 25, and depending downwardly therefrom.

From the `arm lthe long arm of the lever 50 extends diagonallydownwardly and normally lies alongside the barrel 4 and `in engagement with the upper end of the collar 52. The collar 52 is loosely mounted on the barrel so as to be capable of vertical movement thereon, `and this movement is eifected by means of the .vertically-reciprocatiug ,rod 53, arranged in the opening 54 of the disk 3, and in the eye 54L of the lowerend of thebarrel 4. The lower end of the rod 53 `is providedwith an apertured and horizontallvextending arm 55, to which the cord `orcable is connected.

From the arm 55 the cable 56 extends upwardly and over the pulley 57 fof the barrel 4, `and thence `downwardly to the ground `within reach ot' the attendant. Thus it will be `seen that the collar52 may be raised or lowered at will, which willresult in a raising of the longarm of the lever 50, and in a consequent turning ofthe vane 35, whereby it may be moved toward the companion vane and its relation to the platform and said vane changed. This will result ina change in the relative positions ofthe platform and windwheel.

Thus, when the Valles are in their normal positions, the wind will pass over about onehalf of the platform and therefore exert all the infiuence possible on the wheel mounted on it, the remaining half of the wheel being covered by the flange 30. If, however, the vane 35 be moved towardits companion, the oifset 31 will be thrown to the right, so as to cut olf the wind from the wheel, and to cause it to engage onlywith that part which is yet to the right of the said offset. This adjustment may continue until the wheel is nearly completely shaded from thewind, and will result in the varying ofy the speed at which the wheel is moving.

58 indicates two braces which are attached one to the stud 37 and the remaining one to the arm 51, and have their other ends joined to each other by means of the pin 59, passing into the platform 25. The inclined portion 32 is also braced by means of the arm GO, which extends from said portion to the plane IDO ITO

portion of the platform. The shaft lO extends above the block 8, andthe platform v25, and to a point about level with the upper end of the fiange 30, where it is provided with `the wind-wheel.x Y

The Wind-Wheel consists of thehub 60a,

' which is cylindrical in shape and perforated longitudinally so that it may be lixed to the shaft 10. 61 indicates the blades of the wheel, and these are secured in place by means of the ribs 62, formed integral with or rigidly secured to the hub, tbeblades being bolted or riveted to the ribs. The blades are disposed horizontally and are V-shaped in cross-section, so that they will more effectually gather and retain the wind. 'I he number of the blades may be any whichwill suit the exigencies of the occasion orI the convenience of the manufacturer, and the blades are of a height about equal to the height ofthe ilange 30.

It will be' understood that the number of the blades 61 will not approach that of the blades vof the feathering-blade wheel, sincey the two kinds operate on different principles, as will be understood. A further point regarding the principle of the invention lies in the fact that the machine is adjusted lto the direction of the wind without moving the wheel, but by moving a shieldor guard, and thereby covering and exposing the necessary parts, as will be apparent from the aforegoing specification. Y

The operation and use of my invention will not need any detailed description, since it does notdiffer from that attending other windmills, and is, therefore, known. It will suffice for me to say that the machine is well adapted for driving all kinds ofmachinery,

to which windmills are generally applicable.

Theadjustment of the vane 35 is retained by securing-the operating lcord at the `proper position to the frame l, or to any other convenient object.
