WILLIAM P. CLIFFORD, OF IOONIUM. IOWA, ASSIGNOR OF ONE-HALF TO JOHN C. COOK, OF RUSSELL, IOWA.
SPECIFICATION forming-part of Letters Patent No. 772,7 86, dated October 18, 1904.
Application filed. mayiv, 1904.
To all whom it may concern:
Be it known that 1, WILLIAM P. CLIFFORD,
. a citizen of the United States, residing at Iconium, in the county of Appanoose and State of Iowa,.have invented certain new and useful Improvements in Windmills, of which the following is a specification. 7
My invention relates to improvements in windmills,and particularly to that class of windmills having horizontally disposed 'windwheels; and the. paramount object of this invention is to produce agenerally improved windmill which will be better suited to its intended purposesthan any other invention ofthis class with which I am acquainted. An object of the invention is to provide .simple, inexpensive, and efficient means for directing the wind to the wind-wheel in the most advantageous manner and for automatically controlling and regulating the admission of the wind when directed thereto.
With these ends in view the inventlon conslsts 1n the novel construction, arrangement,
, and combination of parts hereinafter dewindmill consists of a series of uprights or supporting-beams 1, suitably secured at their vbase ends and provided at their upper ends scribed, illustrated in the accompanying drawings, and particularly pointed out in the appended claims.
. Referring now to the drawings forming a.
part of this specification, Figure lrepresents a side elevation of my improved windmill. Fig. 2 is a top plan view of the wind-wheel proper and the annularly-disposed wind-guides for directing the wind to the wind-wheel. Fig. 3 is a detail view of a portion of the mechanism for controlling and regulating the wind-guides;
Similar numerals of reference indicate like parts throughout all the figures of the drawlngs.
Upon reference to the drawings it will be seen that the framework of my improved withcross-beams 2, to which there is secured, by means of supporting-arms 3,a convex roofing 1, having a central opening 4 for the exit of air that has spent its force on the windwheel proper. A similarly-shaped roofing or shield 5 is similarly mounted and secured to found necessary or desirable.
Serial No. 208,376r (N0 model.)
cured at their inner ends to the hub of thewheel in any suitable and convenient manner and provided at their outer upper and lower corners with annular bands 11, by means of which the wings or fans are held and supported in proper position and whichserve to give stability to the wheel itself. 7
12 designates annular bands mounted at the top and bottom of the outer stationary portion of the windmill and connected to the inner bands 11 thereof by means of a series of cross-bars 13, adapted to contain and support the upper and lower ends of a series of shafts 14,,mounted in suitable bearings therein and carrying and supporting a series of annularlydisposed wind-guides 15, arranged near the periphery of the wind-wheel at suitable points and adapted to direct the wind to the windwheel and regulate and control the admission thereto or to entirely exclude the same if On the lower ends of the shafts 1 1 there are mounted and secured in any suitable manner a series of sprocket-wheels 16, adapted to receive and be moved by an endless sprocket-chain 17 ,which entirely encircles the same and by means of which the wind-guides 15 are simultaneously set at any desired inclination to regulate the admission of Wind to the wind-wheel 9.
- 18 designates a vane-bar mounted in suitable bearings 19and 20, secured to the frame-- work of the mill and carrying at its lower end a gear-wheel 21 and an operating-lever 22, which said gear-wheel 21 isadapted to mesh With and be thrown into and out of engagement with a second gear-wheel by means of a .lever 23, secured to a movable block in which the lower end of said vane-bar rests. 24 designates a second bar mounted in suitable bearings and provided at its upper portion with a sprocket-wheel 25, which takes into the sprocket-chain 17, and at its lower portion is provided with an operating-handle 26, a miter-gear 27, and a gear-wheel 28. By means of the operating-handle 26, attached to the bar 24, carrying at its upper end the sprocketwheel 25, the same may be moved to the right or left, moving the sprocket-chain 17 and the series of shafts 14, carrying the wind-guides 15, whereby saidwind-guides may be set at any desired inclination to regulate the admission of the wind to the wind-wheel proper. When said wind-guides have been set at the inclination desired, the lower end of the vane-bar 18, carrying the gear-wheel 21, is moved, by means of the lever 23, so that the gear-wheel 21 will mesh with the gear-wheel 28, holding said wind-guides in proper position by means of their connection with the vane-bar 18, carrying the weather-vane.
29 designates a rock-shaft mounted in suitable bearings provided at one end with a miter-gear 30, meshing with said miter-gear 27, and at the other end with a crank-arm 31. (See Fig. 3.)
32 designates a horizontally-disposed bar or arm pivotally mounted on a supportingstandard 33, secured at its base to a supporting-beam 34.
35 designates adjustable balls or weights slidably mounted on said bar or arm 32, and 36 designates a vertical bar secured near one end of the bar 32, to the upper end of which there is adjustably secured a friction-band 37, passing around a pulley hereinafter described. 38 designates another bar pivotally secured at its ends to the end of the bar 32 and the end of the crank-arm 31.
39 designates a driving-shaft mounted in a vertical position in suitable bearings and carrying at its lower end a bevel-gear 40 and at its upper end pivotally-mounted governorarms 41, supported and secured by means of the supporting-arms 42, secured to the movable sleeve or ferrule 43, slidably mounted on the driving-shaft 39 of the governor and secured at its lower end to the horizontallydisposed arm or bar 32.
44 designates a driving-shaft mounted in suitable bearings attached to supportingbeams 45 and provided at one end with a bevel-gear 46, meshing with the bevel-gear 40 of the governor-driving shaft 39 and at its lower end provided with a cone-pulley 47.
48 designates a driving-shaft mounted in suitable bearings provided at one end with a main driving-pulley 49 and at the other with a gear-wheel 50, a cone-pulley 51, and a friction-pulley 52.
53 designates a shaft mounted in suitable bearings immediately above shaft 48 and provided with a gear-wheel 54, meshing with gear-wheel and provided at its end with a pinion 55, meshing with thelarge bevel gearwheel 56, secured to the vertical driving-shaft 6 of the wind-wheel 9 hereinbefore described.
To set the windmill in operation, first ascertain the direction of the wind by means of the weather-vane, (which is out of gear when mill is not in operation,) then turn vane-bar 18 by means of operating-handle 22, so the vane is about one-third (fr) past the center of the wind-blast, then open and set the windguides 15 by means of the operating-handle 26, and then move the gear-wheel 21 into mesh with the gear-wheel 28 by means of the lever 23, secured toa movable block in which the lower end of said vane-bar rests, then set belt on cone-pulleys to suit velocity of wind and speed desired, and, if necessary, more adjustable balls or weights 35 on bar or arm 32 and adjust tension of vertical bar 36 for the same purpose.
When the mill is not running, the vane is disconnected from the governor mechanism by throwing the gear-wheel 21 out of mesh with gear-wheel 28 by means of the handle 23. The action of the vane is an assistant to the governor mechanism in controlling the action of the mill for the following reasons, viz: First, it gives the direction of the prevailing wind, and, second, if wind is not blowing very strong the vane is turned before connecting with governor mechanism one-fourth or one-third or more (as found best) at right angles to the center of the wind-blast, thereby assisting the governor mechanism in opening the guides to let on a larger volume of wind. If the wind is too strong, the vane is turned the other way to assist in diminishing the volume of wind admitted to the wind-wheel. It will thus be seen that the action of the vane will tend to give steady motion to the windmill.
From the foregoing description, taken in connection with the accomjmnying drawings, the operation and advatages of my invention will be readily understood.
l/Vhen the wind is entering too forcibly and driving the wheel at a greater rate of speed than necessary, the governor mechanism will raise and carry the wind-guides 15 into the path of the wind and in front of the wings of fans 10 of the wind-wheel 9 and check the speed of the same, and vice versa.
It is evident from the foregoing description, taken in connection with the drawings, that I provide a windmill or motor which can be easily thrown into or out of operation, which will utilize all the force possible from the wind, which will be automatically regulated to insure a smooth and steady running of the windmill and machinery operated thereby, and which is simple, durable, and thoroughly efficient and practical;
Having thus described my invention, without having attempted to set forth all the forms in which it may be madeor all the ends of said wings or fans, inner, and outer annular bands mounted near the periphery'of said wind-wheel, a series of cross-bars interposed between said inner and outer annular bands, a series of annularly-disposed windguides suitably mounted in' said series of cross-bars, and means for regulating and operating said wind-guides.
2. In a Windmill, the combination with a vertical driving-shaft mounted on a suitable framework, a horizontally disposed windwheel, provided with a series of concave-faced wings or fans, mounted on said vertical driving-shaft, andannular bands secured tothe outer ends of said wings or fans; of inner and outer annular bands mounted near the periphery of said wind-wheel, a series ofvcrossbars interposed between said inner and outer annular bands, a series of annularly-disposed wind-guides suitably mounted in said crossbars, and means for regulating and operating said wind-guides.
3. In a windmill, the combination with a horizontally-disposed wind-wheel,and a series of annularly-disposed wind-guides suitably mounted near the periphery'of said Windwheel; of means for opening and closing said wind -guides, and a weather-vane suitably mounted and provided with means whereby the same may be thrown into and out of engagement with said means for opening and closing said wind-guides.
4-. A windmill, consisting of a suitable I framework, a vertical driving-shaft mounted in said framework, a horizontally-disposed wind-wheel mounted on saiddriving-shaft, a
series of wind-guides pivotally arranged near the periphery of said Wind-wheel, means for opening and closing said wind guides, a weather-vane suitably attached to said framework, and means whereby the same may be thrown into and out of engagement with said means for opening and closing said windguides.
5. In a-windmill, the combination with the wind-guides, and mechanism for'regulating said wind-guides; of a weather-vane suitably mounted, and means for throwing said weather-vane into and out of engagement with said mechanism for regulating said windguides.
