WIND-MOTOR.

Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed May 27, 1920. Serial No. 384,644.

To all whom it may concern:

Be it known that I, CHARLES H. KILLOUGH, a citizen of the United States, and a resident of Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Wind-Motors, of which the following is a specification.

My invention relates to wind motorsformerly called windmillsand has for its general object to provide a wind-motor adapted for the driving of light machinery of any kind by direct rotary motion. Standard windmill construction is unable to do this kind of driving as it only provides for reciprocating a pitman.

The invention consists, first, in means for driving one or more countershafts continuously; second, in means for holding the head (or motor proper) against rotating in a horizontal plane except when the direction of the wind is changing; third, in automatic means permitting the head to turn during such intervals; fourth, in means for conveniently stopping the motor while the wind is blowing; and further, in certain minor features of construction and opera tion, all of which are hereinafter set forth.

In the accompanying drawings, Figure 1 is a partial elevation of a motor embodying the improvements, many parts being shown in section; Fig. 2, a sectional elevation of gearing at the base of the motor; Fig. 3, a detail of a cam and roller, viewed on line A-A of Fig. 1; Fig. 4, a horizontal sectional detail viewed on line B-B of Fig. 1; Fig. 5, a detail view in elevation, showing certain parts seen on Fig. 1; Fig. 6, a plan view of means for controlling the vane; Fig. 7, a detail of guides for a deflectingcable; Fig. 8, a detail viewed in section on line (3-0 of Fig. 1; Fig. 9, a plan view of the cam shown in Fig. 3.

The wind-wheel 1 and the vane are of ordinary or any preferred construction.

The tower 3 may be of ordinary construction excepting as hereinafter noted. The legs 3 of the tower are joined at their upper ends to a ring 4 provided with a race for a ball-bearing 5, on which the head frame casting is rotatably mounted. This casting comprises the lower and upper parts 6, 7 which together form a closed housing when handhole-plate 8 is on. In the housing are split bearings 9, 10 for the wind-wheel shaft 12.

Rotation of the wind-wheel is transmitted as follows: through shaft 12, bevel pinions 13, 14, 15 to a bevel gear wheel 16, through a vertical shaft 17 which extends downward to a point near the ground-through bevel gear 18 to bevel gears 19, 20, which drive two countershafts 21, 22.

Bevel pinions 13, 14 are each keyed or p nned on shaft 12. The intermediate. bevel pinion 15 is provided with an integral spur gear 23 which drives a spur gear 24 in tegral with bevel gear 16, which is keyed on shaft 17 This gear arrangement offsets the greater wear of shaft bearings that would result from the use of but one drive pinion.

Equal wear and driving mesh of this gearing is promoted by the torsion of a spring 25 which is so clearly shown that a description of its effect is unnecessary.

The gearing described may be run in oil. Oil may enter and fill the tube 26, but cannot pass below a packing 27, having a gland 28. Shaft bearing 10 also has a packed gland 29.

The bottom bearing 30 of shaft 17 is formed in a pedestal 31. The weight of said shaft is supported through the medium of its upper and lower gears 16, 18, both keyed thereon. The hub of gear 16 is mounted on an annular ball-bearing 32. The face of bottom gear 18 is formed with a ball-race, turning on annular ball bearing 33 on the pedestal 31.

The vane 34, shown entire in Fig. 6, has its hub lugs 35 keyed on a vertical rockshaft 36, journaled in lugs 37, 38 on the housing 67. Normally, the vane is held at an angle normal to the wind-wheel by the pull of a tension-spring 39, acting on an arm 40 fixed on shaft 36 and being anchored to a fixed lug 4:1.

With the wind-wheel in operation and a load on a driven shaft as 21 or 22, there will be a tendency for the head to rotate bodily upon its bearings. Such motion is of course necessary when the direction of the wind changes, but when the wind blows from one quarter, such bodily rotation must be prevented. This is accomplished by a device illustrated on Figs. 1, 3, a and On the bottom of the lower housing part .6 is cast a depending annular flange 44. In this flange is a notch 45. Just beneath flange 44, an annular flange 4:6 is cast upon ring casting 4, and-this flange is provided with a sutlicient number of equally spaced notches 47. A latch-lever L8 is set in line with notch 45, said lever being pivoted on a pin 49 held by a lug 50 on casting 6. The inner end otsa'id lever lies partly in notch 45 and partly in any one of the series of notches t'7.---On the inner arm of lever 48 is a weight 51, and on the outer end of said lever is a small roller 52. IVhen the latch formed by the inner end of the lever is held down by the weight 51, the head or housing is heldagainst rotation. To complete the utility of the device, I further provide'means whereby the turning of the vane 34 on its own axis, from its normal angle, automatically releases the head and permits it to turn. Contacting the roller 52 is a cam plate 53 having its hub keyed upon the vane'shaft '36. In-the lower face oi the cam plate is a central recess 54 formed with inclined approaches. Normally, the weight 51 holds the roller 52 up in said recess (when the vanes angle is normal). vane is deflected, either manually or by the wind,the rocking of shaft 36 will turn the cam plate 'far enough to force its roller downward a suflicient distance to lift the latch end of lever as out of a lower notch. As soon as lateral pressure upon the vane ceases, the spring 39 will restore the vane to normal angle, bringing the cam recess 54 to center, whereupon the latch end of lever 48 will drop into the first notch it en'coun ters, thereby latching'the headto thetower as aforesaid.

In the drawing I have shown the following construction of means for stopping the wind-wheel while the wind is blowing by turning the vane through an angle of ninety degrees, the effect of which is well known.

.It is to be understood however that any equivalent means for deflecting the vane may be employed, and I do not limit my claim to the following mechanism.

Asecond crank-arm, 55, is keyedonvaneshaft 36, or it may be integral with arm 40 as shown. The normal angles of said arms are shown on Fig. 6. The operating cable 56 is connected to arm 55 as shown, passes over grooved guide- rollers 57, 58, 59 down through the center of the hollowshaft 17 and supports a short depending rod 60 havinga nut'61 on itslower' end." Supported by this nut is a small annular ball bearing Whenever the 62, upon the upper half of which rests a crosshead 63 comprising a pair of oppositely directed lugs 68' passing slid-ably through vertical slots 6-1: in the shaft. Mounted on lugs :68 are a pair of anti friction rollers 65, which support a nonrotary ring 66, connected pivotally by pins 67 to a yoke 68, formed intermediate the ends of a lever 69, fulcrumed at about the point f to a member of the tower. Motion is communicated to this lever directly or through a pull-cord 70. By drawing this down the cable'56 is drawn down when it is desired to stop the motor, this being effected by deflecting the vane as aforesaid. The cord 70 is to be tied down until the operation of the motor is again desired. The rotation of the vertical shaft 17 will of course rotate the crosshead 63, but this will not place any strain nor wear upon the lever-actuated parts above mentioned.

It will thus be apparent that my invention provides a practical wind-motor by which light machinery may be driven by continuous rotation.

By the term .head in the claims I mean to designate the rotatable housing and the various bearings forming parts thereof.

Having now described my invention,what I claim and desire to secure by Letters Patcut is: V V
