WINDMILL.

Application filed June 3, 1926. Serial No. 113,486.

This invention relates to windmills and has special reference to a windmill wherein the wings revolve about a vertical axis.

One object of the invention is to improve the general construction of devices of this character.

A second important object of the invention is to provide an improved "term of wing for such windmill.

A third important object of the invention is to provide a windmill construction wherein the wind power will be exerted in an inn proved and highly elficiont manner.

A fourth important object of the invention is to provide an improved and novel form-of shutter arrangement for the wings of such a windmill.

A fifth important object of the invention is to provide improved arrangement for controlling the etlective area of the *ings in such a windmill.

A sixth important object ot the invention is to provide a novel arrangementwherein the wings are arranged in pairs, the wings of each pair being provided with means for simultaneously controlling their effective areas.

A- seventh important object the invention is to provide a novel arrangement of sets of wings of ii'l'ipii'oved character, the ar angement being such that each sethas its wings brought into operative position at equal intervals, the wings of the several sets also being brought successively into operative position at equal intervals.

An eighth important object of the invention is to provide an improved and novel term 01" pump jack for use in connection with this windmill.

With the above and other objects in View as will be hereinattn? apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrator in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters ofreterenceindicate likepartsin the several views, and:

Figure 8 is a side elevation of said pump jack.

Figure 9 is a detail elevation of a portion While a tower or derrick has been shown in the accompanying drawings much of the bracing has been omitted for the sake of clearly disclosing the invention itself.

It is not to be understood that such omission of bracing is necessary as the invention is not limited to application to any particular form of tower but I may use any tower which I may find tobe of suitable strength and construction. Furthermore certain details such as bearings and the like have been shown and will be described. in order-that the invention may be understood. 1 do not limit myself, however, to the exact form of constructional details of this character here shown and described since I may use such types of bearings and the like as I may find expedient in any particular case.

Again, while it will be found that the invention as described calls for five sets of wings with tour wings in each set, such invention is broader than any particular numbersof sets or wings and I am not to be confined to the numbers ll find at this time to be most expedient.

In the embodiment ot the inventionhere disclosed there is shown a tower or derrick having upright corner posts 10 supportin a platform l1 at thetop. This top is reached by a suitable stair 12. These parts may be of any desired material and shape and a =u-sef-ul-1naterial for theposts is found to beisteel angle bars. Supported on theplatform is a bearing13 and adjacent the bottom of the tower is a ball bearing of the thrust type. This-latter bearing consists of a bot tom plate 14: provided with ball grooves in which are held balls 16. On these balls rests an upper plate 17 having a collar 18 which is firmly secured to the power shaft- 19. This shaft is also journalled in the bearing 3 and other intermediate bearings, such as is shown at 20 may be provided for long shafts and high towers. Preferably the plate leis made of suitable hard steel and is square in form so that bars 21 may be bolted thereto, as shown inFigure 5, and extend diagonally to the corner posts 10 and there be firmly secured. Braces 22 may also be used to render the structure rigid and thus provide a firm support for the hearing. The intermediate hearing may be supported in like manner if desired. Projecting up from the fixed plate 14 is a pivot pin 23 whereon is pivoted a brake. lever 2st having one end bearing against the shaft 19 and its other end worrzing over a notched bar 25 of the type usual for holding such levers in adjusted position.

Mounted on the foundation 26 are suitable standards 27 which support horizontally alined bearings 28 wherein is journalled the main drive shaft 29. On the lower end of the shaft 19 is a bevel pinion 30 which meshes with a bevel gear 31 fixed on the shaft 29. On one end of the shaft 29 is a bevel pinion 32 which meshes with a bevel gear 33 fixed on a shaft M by means of which power may be transmitted to any desired machinery. Also one or more belt or band wheels 35 may be fixed on the shaft 29.

Fixed on the portion of the shaft 19 which projects above the platform 11 is a series of spaced center plates 36 each having a collar 3'7 projecting from its underside. This collar surrounds and is securely bolted to the shaft. I have found that it is best to use five of these plates and their accompanying parts but I have here indicated but two of such plates with their accompanying parts as it is deemed unnecessary to extensively duplicate these parts in the drawings and the invention can be well understood without such showing. From each center plate radiates arms 38, preferably four in number and arranged in right angularly disposed pairs so that the arms are evenly spacedcircumfen entiall The arms of each plate are dis placed angularlywith respect to the arms of the plate nest below one fifth of a circle or seventy-two degrees. Bolted to each of the arms is a horizontally extending wing frame 39 and through the vertical ends of each frame extends a shutter rod l0. On each rod is swingingly mounted a series of shutter leaves or vanes 11. The rod 10 is arranged near the top of the respective frame and extends through suitable thickened portions near the tops of the leaves so that the normal tendency of these leaves is to hang vertically. In the bottom member of the frame is a rabbet 42 which receives the lower ends of the leaves when in vertical position and these leaves bear against the vertical side of this rabbet when in fully closed position and acted on by the wind. Thus the leaves are limited in movement in one direction. These leaves can swing from vertical to horizontal position as they do when the windmill revolves and the wind is blowing against the backs of the leaves. In rder to limit the lift of the leaves stop lugs 43' are provided on the upper member of the frame. In the larger sizes of windmills it is advisable to support the shutter rods intermediate their ends and for this purpose a bracketlt having depending bearing ends may be fixed'to the frame. A. trip bar 4.5 extends along the front of each series of leaves and is provided with upturned ends 46 fixed securely to the shutter rod. Fixed on the inner end of each shutter rod is a rock arm 47 to which is connected one end of a pull cable 48. These pull cables are connected in pairs to rings 19 provided with hand grips 50. The cables connected to each ring extend to the rock arms of diametrically disposed wings and lead through cable guides on a table 51 fixed to the shaft 19. Thus by pulling on a hand grip opposite series of leaves may be raised to partially or fully open position as desired and the effective area of the wings diminished to any desired extent. This adjustment is not only useful when it is desired to stop the windmill (in which case all the trip rods are raised) but is also useful, when it is desired to reduce the speed and especially when high winds are blowing.

In order to prevent too great movement of the trip bar and to brace the same at the middle, a brace 47 is fixed to the top and bottom members of the frame to the rear of said trip bar.

In order to produce even and smooth motion of the device and to prevent the varia tions in speed frequently noticed in windmills when gusty winds are blowing, there is provided on the shaft a collar 51 firmly fixed to said shaft and supporting a pair of arms 52 carrying pins 53 which pass through slots 54 formed in governor arms 55. These arms are pivoted at their upper ends to a col.- lar 56 slidably mounted on the shaft 19 and have at their lower ends heavy governor balls 57 by which the collar is normally held raised. These balls, upon increase of speed move outwardly and upwardly and thus, through their fly wheel effect, tend to regulate the speed and cause the device to revalve evenly.

On the remaining end of the shaft 29 is fixed a crank disk 58 carrying a crank pin 59. This disk and pin are used for converting the rotary motion of the shaft 29 to reciprocatingmotion such as is used in 001111667;

tion with my pump ack which will now be described.

This pump jack includes a U-shaped frame having a base 60 securely clamped to the upper end ofa casing 61 and projecting upwardly from this casing to move up and down therein is a sucker rod 62 having a series of spaced holes 63 in its upper end. A headed pin 64 is provided which may be inserted in any desired hole 63 and is suitably secured by a cotter pin so that the pin cannot slip out. It may be here noticed that all other pins are provided with suitable cotters for the same purpose. On the pin 64 is pivoted one end of a link 65 which has its other end pivoted to the crank pin 59 and it is to be noticed that this crank pin may be mountedin any one of a series of holes 66 in the disk 58 so that the throw of the crank may be thus adjusted to suit desired movements of the sucker rod 62. At each end of the base portion 60 is an upright arm 6? which carries at its upper end a pin 68 whereon is pivoted a lever 69, the lever having a series of holes 70 therein so that the lever may be selectively positioned on the pin. The inner ends of these levers carry pins 71 on which are pivoted the forked links 72 vhich have their forked ends straddling the upper end of the sucker rod and are pivotally connected thereto by a pin 73 passing through one of the holes 63. Slidably mounted on the levers 69 are weights 74 which are secured in desired positions by pins 75 passing through selected holes 70. Thus these weights assist in counterbalancing the weight of the sucker rod. On top of the casing 61 rests a plate 7 6 and above this is a second plate 77 which is held from sliding up on the sucker rod by a pin 78 which may be inserted through any desired opening 63 to properly tension the coiled spring 79 surrounding the sucker rod between theseplates. A third plate 80 is similarly positioned. by a pin 81 and between the second and third plates is a coiled spring 82. The base 60 is provided with clamp bolts 83 and these bolts carry the lower ends of zig-zag springs 84 which have their upper ends firmly secured to the plate 80. By means of this arrangement the weight of the sucker rod is properly balanced and the pump operated with very little loss of power.

It is to be noted'tha't lips 43 are turned up on the wing between the 'stops'l3 to defiect the wind downwardly.

It will be noted, also, that theweights 74 are the means of entirely balancing "the 'suck'erro'd weight in all open field, farm or ranch pumps but where space is a consideration the supplementary aid of adjustments in "springs 7 9 and 82 by means of manipulating springs 79 and S2 to a greater upward tension thereby lessening the necessary length of levers 69 and the size of weights Tet which may be necessary in engine rooms or between close walls.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

it is obvious thatminor changes may be made in theform and construction of the invention without departing from the material spirit thereof.
