WILLIAM C. BROWNELL, OF PUEBLO, COLORADO.

WINDMILL Specification of letters Patent.

Patented Mar. 11, 19.19.

Application filed October 22,1917. Serial No. 197,952.

To` all-whom' t may concern:

Be it known that I, WILLIAM C. BROWN- ELL, a citizen of the United States, residing at. Pueblo, in the county of Pueblo and State `of Colorado, have invented certain new and vruseful Improvements in Windmills, of

whichl the following is `a specification.

This invention relates to wind mills, and

its primary object resides in the provision of a wind--actuated mechanism whose driving power is increased by the peculiar arrangement of a plurality of vane-wheels which cooperate to furnish motive power to a driven shaft. l

A' further objectof the invention resides in the provision of an automatic governor for regulating the movement of thewind- 'wheels und'er varying wind :pressures to maintain lthe driven-shaft at a substantially uniform rate of speed. y

Still other objects of. the invention relate to details of construction 'and arrangement of parts, allv of which will fully appear in the course of the following description.

illustrate an embodiment of my invention and in which similar characters of reference designate corresponding parts in the several views, i

Figure 1 is a plan view of the operating mechanism of my improved wind-mill, in its preferred form,

Fig. 2, a section taken along the line 2 2,

' Fig.l 1, and

Fig. 3, a section along the line 3--3, F ig. 2. i

Referring to the drawings, 2 designates a ysuitably supported platform upon which is mounted a base 3 for the support of the voperating parts of the wind-motor.

The base provides a step-bearing for a rotary standard 4f which has at its upper end, two axially. alined boxes 5 for the support of the driving shaft 6 of the motor.

The shaft carries at its opposite ends, the front and rear wind- wheels 7 and 8 the vanos of which are pitched in the same direction to impart a rotary motion to the shaft by action of the wind.

The driving shaft carries a beveled gearwheel 9 which transmits its rotary motion to a corresponding wheel 10 at the upper end of an upright shaft 12 extending through alined bores in the standard 4 and the base 3' and supported for rotation upon a suitable bearlng 13.

Ymitted fby means In the accompanyingdrawings which' The movement oft-he driven shaft is transof a pair of beveled gearwheels 14 and l5 to a crank-shaft 16 set at right angles thereto, for the operation of a pump or other mechanical device, through the medium of a pitman 17.`

An auxiliary wind-wheel 18 the vanes of which are pitched reversely with respect to those. of the Wheels 7 and 8 at the ends of the driving shaft, is mounted for independent rotation in one of the bearings of the standard 4 by means of a 'tubular hub 19 through which the shaft 6 loosely extends. i

The hub carries a beveled gearwheel 20 which meshes with the before-mentioned gear-wheel 10 at the end of the driven shaft,.

opposite to that at mally extends in parallel relation to the y driving shaft, or at right angles to the piarallel planes of rotation of the Vwind wheels.

The rudder is fastened at the end of a 'shank or stem 22 provided with a collar 23 for its rotary support upon a iange 24 at the lower end of the standard 4, ing a counterbalancingweight l25.

i governing rudder 26 of smaller area is mounted at the end of a shank 27 in rigid connection with the rotary standard, as best shown in Fig. 3 of the drawings, and eX- tends at right angles to the primary rudder 21 with which it is connected by means of a leaf-spring 28.

This spring is at its ends att-ached to the.

and carry- In the operation of my improved windmotor, the primary rudder 21 normally maintains. the wind-wheels in the proper position to face the wind'and thereby furnish the motive power required for the rotation of the driven shaft.

The wind after acting on the front wheel 7 18 for its rotation in .the opposite direction after which it engages the rear wheel '8 which is turned in the same direction as the first-mentioned wheel.

Since the gears on the. shaft and the hub of the auxiliary wheel act upon the` gearwheel on the driven shaft at opposite points, the rotary movements of the three vanei do ' tion te the aircurrents, and the operating on said driving shaft in mesh vvit n ially in the direction of the `vvind, the

the Wind.

wheels are combined to impart a, rotary niotion to the drive-n shaft with a poiver greater than that obtained either a single wheel or by tivo uieels the vanes of which are pitched either in the same. or in opposite directions.

Since the primary rudder extends norgoverning; rudder, beinggY of smaller area, is nnder the saine eonditions kept in facingrelaparts of the motor are thus under normal conditions held constantly in the proper pd sition relative 'to the direction of the vrind.

Vl/Vhen, hoivever, the force of the ivnd increases beyond a certain predeterminedliinit established by the resistance of the spring, 28, its action upon the governing blade Will cause the spring to yield, With the result that the standard is inovedabont its axis and the vane Wheels supported thereon are turned to face at an angle to thedirection of The motive power of the Wheels is thus automatically controlled in accordance with Wind'variations to efleot the rotation of the driven .shaftr at a substantially uniform rate of speed. j

l desire it understood that. While l have described and shown the embodiment of my invention which at present appears simplest and best adapted for its purpose, such mi- `nor changes in 'the details of construction and arrangement of the operating', transmis- 'sion and controllingmechanisms of my inn proved Windmill may be resorted to as are Within the scope of the followingg` claims.

I Claim:

l. ln a Wind mill, aV driving shaft, ivind Wheels affixed to the. ends of said shaft, a driven shaft disposed at. right angles to the driving shaft inwardly froin the ends of the latter, a gear on said driven shaft, rear h the said driven shaft gear, anauxiliary Wind wheel on said driving' shaft and rotatable independently of the latter, and a gear carried by said auxiliary ivind ivlieel and in niesh with the said driven shaft gear.

ln a wind mill, a drivingshaft, a yoke having spaced bearings one of which supports said shaft near one end of the latter, a sleeve inclosinp; a portion of said shaft near the other end thereof and rotatably mount-ed in the otherof said bearings, a bevel .blades pitched opposite to the inclination of the blades of the first mentioned Wind wheels.

3. ln a wind lnill, a driving sl1aft,a volte liiviirrI its arms embracing said driving shaft inivardl)v from the ends thereof, a driven shaft rotatable in said yoke, a bevel `gear atlixed to said driven shaft, a bevel ,gear aiiizied to said driving shaft and in mesh with the said driven shaft gear, asleeve inelosing and supporting' said driving' shaft near one end thereof and rotatable in one of said volte arms, a bevel gear carried by said sleeve and in mesh-With said driven shaft A:rear diametrically opposite the point of Contact of the said driving; shaft gear thereivith, wind ivheels atlixed te the ends 0f said driving shaft, and a Wind Wheel carried by said sleeve.
