WILLIAM F. BRETT, F DECATUR, ILLINOIS.

WINDMILL.

To all whom it may concern:

Be it known that I, VILLIAM P. BRETT, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Windmills, of which the following is a specification.

This invention relates to improvements in the class commonly known as the upright or vertical wheel windmill; and the objects of this invention are, first, to provide a windwheel that will be light in weight, sensitive in its governing qualities, and conveniently arranged for assembling in working order and for knocking down and crating in small space for storage and shipment; second, to provide details of construction that in the main features are suitable to all sizes of windwheels; third, to provide a wheel frame or spider in which the spokes are secured to the hub and rim in such manner that there will be no tendency of their working loose during the operation of the wheel; and fourth, to provide a wheel frame of the tension spoke type that is suitable for either the feathering blade, or the solid type of windwheel. I attain these objects by the novel details in the construction, arrangement and operation of the several parts of the mechanism which will be apparent from the detailed description hereinafter when read in connection with the accompanying drawings forming part thereof, and wherein preferable embodiments of the invention are disclosed and various disconnected parts shown for the purpose of illustration.

In the drawings Figure 1, is a front view of the wheel and governor with parts broken away; Fig. 2, is a side view of the governor and a portion of the wheel; this figure also shows the crank disk, brake wheel, and means for controlling the speed of the wheel and of putting the same into and out of action; Fig. 3, is a side view of the brake wheel 13 of Fig. 2; and the controlling mechanism of the windmill, showing how said mechanism is anchored to the adjacent portion of the main frame or turntable of the windmill; Fig. 4, is an edge view of the cross bar 3 of Fig. 12; Fig. 5 is an edge View of a portion of rim 2 of Figs. 1 and 2 and shows one method of connecting the spoke 4 to the rim 2; Figs. 6, 7, 8, 9 and 10 are views showing some of the various forms Specification of Letters Patent.

Similar letters and figures refer to similar and corresponding parts throughout the several views.

In Figs. 1 and 2, 2 and 2 are the outer and inner rims of a feathering blade windwheel, the outer rim 2 being anchored to the hub portions 5 by means of the spokes t, and the inner rim 2 is suspended substan tially concentric with the outer rim by means of the stay or distance rods 10 preferably one on each side of each of the sails, The three blades or sails 1, 1, and 1" comprise a section of sails, each of which is pivotally anchored to said rims and all are adapted to be governingly actuated by one arm 4 of the governor part 5 which is carried by the wheel shaft 9" and is adapted to rotate therewith and to oscillate independent thereof. The three sails of the section are connected together by the links 0, which are secured to the projections 3 of the cross bars 3 of the sails and are adapted to be actuated in unison by means of the link or bar 4 which is preferably connected with the center sail of the section at one end and to the end of arm 4 at the other end; and thus any number of sections of sails may be actuated by means of a corresponding number of arms 4t which are substantially equally spaced about and radiate from the governor part 5; thus it is readily seen that the windwheel may comprise any desired number of sail sections and that each section may comprise any desired number of sails, and also that all of the parts of each section are duplicates of and interchange able with the corresponding parts of all of the other sections of the wheel. The governor comprises the central or hub portion 6 (see Figs. 1 and 2) which is rigidly secured to the shaft 9 which has its bearing in the tubular wheel shaft 9 and is adapted to oscillate therein and rotate therewith.

The hub or central portion 6' carries the two arms 6 which are adapted to have the parts 6 pivoted to the outer ends thereof, and part 6 of each arm carries a rod or extension 8 on which are adjustably fixed the weighted governor sails 9 and the clips 8; the curved rod 7 provided with the stop nut 7 at its outer end passes through an aperture in the extension 7 of each of the parts 6 and is adapted in conjunction with springs 11 and 11 and the intervening connecting parts 4t, 1, 0, and 8 to normally hold the sail carrying extensions 8)v substantially at rightangles to the arms (5; the spring 11 being attached at one end to the wheel rim 2 and at the other end to the cross bar 3, shown in broken lines in Fig. 1 and solid lines in Fig. 2, preferably of the center sail of each of the sail sections of the wheel, thus normally holding the wheel sails full in the wind and the governor sails so as to pass edgewise through the air as they revolve with the wheel, with the wheel and governor sails in these positions one of the spokes of the part 5 bears against the stop 35 which is made rigid with the hub part 5, and the arms 6 of the governor bear against the stops 5 which are carried by the part 35 which is rigidly secured to the shaft 9", the part or spider 5 being free to oscillate on shaft 9" between part 35 and the hub 5 and the part 6 with the arms 6 being carried by the oscillating shaft 9 it is readily seen that the entire governor mechanism is yieldingly held against stops 5 and 35 by the springs 11 and 11 during the operation of the wheel in winds that are not strong enough to cause the governor to act, but if a strong gust of wind should strike the wheel and suddenly increase the speed thereof the inertia of the governor mechanism will instantly act in overcoming the tension of the springs 11 and cause the sails 1, 1, and 1 to turn sufliciently out of the wind to effect the gradual. speeding up of the wheel until the velocity is attained that will cause the governor sails 9 with their attachment weights 8 and arms 8 to swing outward on pivots 36 by centrifugal force, and as sails 9 swing outward they present an increasing air resisting surface against which the air acts and supplements the centrifugal force in governingly actuating the wheel sails, and with the sails 9 partially extended in a good operating wind there is established an operating condition of the governor under which it is very sensitive in its governing qualities by reason of the harmonious action of the centrifugal and centripetal forces of the arms 8, sails 9 and sail attachment weights 8 and the resistance of the air thereagainst and the momentum and inertia of the entire governing mechanism which in a good strong wind will cause the Wheel to rotate at an approximately uniform and unvarying speed regardless of wind and load variations in connection with which the wheel is adapted to operate.

The broken part let (see Fig. 2) represents a portion of the windmill turntable which carries the shaft 9, the main part of the bearing for the shaft 9 being shown as broken away and 13 is the crank disk which is secured to the inner end of the wheel sh aft 9, the part 13 is a brake wheel formed as shown in Fig. 3 and is rigidly secured to the inner end of the governor shaft 9. and is adapted to oscillate therewith, with the wristpin 13 extending through the aperture 14:, and in connection with the brake 12, the

spring 11", and the pull cord 12" constitutes a means by which the windwhecl may be optionally controlled by a person at a distance therefrom by means of the cord 12' which may be made to extend to any desired position; this optional controlling of the wheel is accomplished by pulling downward on the cord 12" which sets the brake 12 on the wheel 13 holding it againstrotation to the extent of causing the governor mechanism, above described, to overcome the tension of springs 11 and turn the sails to their inactive position, the forward movement of the wheel effecting this result when the brake 12 is applied to the wheel 13, but when the cord 12 is not drawn downward the springll, which is attached at its upper end to the bracket 12 will normally hold the brake free of the wheel 13 and the springs 11 will hold the wheel sails in their active positions. I The slot 14 in the brake wheel 13 through which the wrist-pin 13 extends is of such length as to permit the brake wheel to oscillate independent of the crank-disk to the extent that when the wristpin 13 bears against the metal of the brake wheel at one end of the slot the wheel sails will be held full in the wind and when the wrist-pin bears at the other end of the slot the sails will be held full out of the wind and when the wind-wheel is in operation with the brake 12 free of the wheel 13 the governor will cause the shaft 9 and wheel 13 to oscillate so that the wrist-pin 13' may not bear against either limit of the slot 14' but the brake wheel may be continuously making short oscillations relative to the crank-shaft and disk; the position of the wristpin in the slot being determined by the relative conditions of the load carried by the Wheel and the force of the wind by which the wheel is being impelled.

Great strength is required in windwheels for heavy work and it is important that all of the material used in their construction should be-distributed to the best advantage possible and in order to accomplish this I provide a rigid central or hub portion as shown in either of Figs. 1, 2, 11, 18, 27, 28, 33, and 34, all. of which are adapted to be assembled in working order with any of the spokes shown in, these drawings excepting the form shown in Fig. 21. which requires the special construction of hub attachment shown in Figs. 17 and 32.

Figs. 9 and 10 show two groups each of which comprises four spokes made of one endless wire or red, the spokes in Figs. 1, 2 and 11 being of the form shown in Fig. 9 and the spokes shown in connection with Figs. 18, 27, 28, 33 and 34: are of the form shown in Fig. 10. and in all of these figures each spoke is indicated by the reference figure 4; Fig. 11 is an enlarged view of one of the hub flanges 5 of the wheel shown in Figs. 1 and 2 as seen when looking in the direction of the length of the wheel shaft; .in these figures the flanges stand substantially at right angles to the wheel shaft and are provided with the oblong apertures 16 through which the loops 1 1 of the spokes are adapted to be forced and secured therein by means of a pin or key as shown at 16 in Fig. 11. The spokes shown in Fig. 9 when spread as shown in Fig. 10 are in shape to be assembled in connection with either of the hubs shown in Figs;27 and 31 and in each of-these hubs the loop 14L stands substantially at right angles to the wheel shaft instead of parallel therewith as shown in Figs. 1, 2, and 11.

in Figs. 18, 27 and 28 the loops 14" are designed to be clamped between the flanges 26 and 27 (see Fig. 27) and embraced by the two lugs 27, of one of the flanges, as shown in Fig. 28 with the bolt 27 extending through the loop and flanges, thus securing the spokes rigidly to the hub. The hub shown in Figs. 33 and 34 is a pulley shaped cylinder or shell 28 and is provided with a series of oblong apertures near each edge portion of the rim substantially as shown at 16 in Fig. 34: and the loops 1 1 of the spokes are adapted to be inserted and secured with a split key substantially as shown at 16 in Fig. 34, thus it is apparent that the spokes shown in Figs. 9 and 10 are adapted to be attached to the hubs and outer rims of the wheels either as shown in Figs. 1, 2, and 11. or as shown in Figs. 18, 27, and 34, and as the rim 2 (see Figs. 1 and 2) is secured to the spokes of the wheel by means of keys substantially as shown at 16 in Figs. 2 and 19 it is also shown that all of the spokes have substantially uniform size and strength throughout and that there is no possible chance for loosening at any point or breakage of any of the spokes in a properly proportioned wheel, and that wheels of this type of construction may be made exceedingly light in weight and of great strength.

In the two types of wheel shown in Figs. 2 and 18 the outer rim of each type is connected With the hub of the wheel by as many spokes as may be necessary, considering the work to be accomplished by the wheel, and is prevented from bulging out between the spoke attachments by means of the stay or distance rods 10 in the type shown in Figs. 1 and 2, and by the tension wires 25 in the type shown in Fig. 18, and the inner rim in each type is preferably anchored to these rods or wires exclusive ofany anchorage to either the spokes or hub of the wheel. Means for varying the distance between the outer and inner rims and maintaining a fixed distance there-between, in line with the sail pivots, in the type shown in Figs. 1 and 2 is provided in the running thread and nuts on the rods 10 substantially as shown in Fig. 15, thus providing means for accurate adjustment to the sail pivots as well as giving extra strength and any desired uniform tension to all parts of the wind wheel. In the type shown in Fig. 18 the tension wires 25 are made with a suitable loop somewhat as shown at 36 and 36 in Figs. 22 and 23 and are secured to the outer rim by' means of a key the same as the spokes are attached thereto; the inner rim in this type of wheel may consist of a number of sections of round rods formed in any suitable shape but preferably somewhat as shown in Fig. 26 and are provided with right and left threads adapting them to be secured in operative position substantially as shown in F ig. 18 by means of the turnbuckles 22 and these sections may be slightly crimped as shown in Fig. 26 so as to equally space the inner ends of the sails and the tension wires 25. For the solid type of wheel the sails are preferably provided with a clip or anchorage flange as 32 shown in Figs. 19 and 20 or they may be anchored to the outer rim and held at the proper angle to the wind by means of the braces 32 and 33 shown in Fig. 19 also, and the inner ends of the sails are provided with either the aperture 33 or the eye 23 as shown in Figs. 20 and 25. The inner rim 22 see Fig. 18 is put through the eyes or loops 36 (see Figs. 22 and 23) of the tension wires 25 one sect-ion at a time and then secured together by means of the turnbuckles 22, and the sails'may be secured to the outer rim, which is preferably composed of detachable sections secured together as shown at 3 1 in any convenient and substantial manner but preferably in the usual way by means of a bolt or rivet through the rim and clip 32 as shown at 3 1 in Fig. 19 for the sails that are located between the tension rods 25 and for the sails that are located adjacent to these rods and the spokes the same key that secures the wires and spokes may be made to also secure the sails as shown at 16" in Fig. 19. The wire 34 is attached to the outer rim and twisted into the turnbuckles after they have been adjusted and are simply to prevent the turnbuckles from twisting so as to maintain the tautness of the inner rim 22. Before securing the wires 34 and after assembling and adjusting all of the other parts of the wheel any desired. tension may be given to the spokes and uniformly to all tension parts of the wheel by so turning the turnbuckles 22 as to contract the inner band 22 thus causing the outer band or rim to tend to bulge outwardly at the points of the spoke attachments. In this type of windwheel it is preferable to so proportion the sails that the surface outside of the rim 22 is approximately the same in area as the portion that extends inwardly so that the rim 22 carries substantially the entire load of the wheel, and with the sails thus balanced on the outer rim the inner ends may be secured so as to prevent any impairing vibration of the sails by means of the coiled extension springs 25 which are simply hooked into the aperture 33 at one end and into one of the crimps 23 (see Fig. 26) of the inner rim 22, the springs 25 being under such tension as to maintain the proper spacing and steadiness of the sails, thus it is readily seen that with this yielding con nection for the inner ends of the sails a substantially uniform stress is exerted upon all of the sails regardless of what the working strains of the wheel may be, and that substantially the same construction of wheel frame or spider is adapted to use in connection with either the feathering blade or solid wheel type.

In the smaller sizes of solid wheels the inner rim 22 may pass through the eyes 23 Fig. 25 without throwing any undue strains on any of the sails thus cheapening the construction of the wheels.

Instead of the construction of sails shown in Figs. 1, 2 and 13 the sails of the feathering blade type for the large wheels are preferably provided with a skeleton or frame work comprising longitudinal slats 18, 18

and 18 and 19 and end slats 17 and 17 made in two parts detachably secured together by means of cross bars as shown at 3 and 3 in Figs. 4 and 12 in which n indicates detachable screws which pass through the cross bars 3 and 3 and are screwed into the longitudinal slats thus detachably securing the two parts, into one rigid sail frame. 17 is an apertured enlargement in the bars 3 and 3 and is adapted to receive the pivot pins 19 and 19" which are adjustably secured therein by means of the setscrews 37 (see Figs. 41 and 15), and in the medium and smaller sizes of wheels the pivot pins 19 and 19 may have their bearings in apertures through the rims of the wheel as shown in Fig. 15 but for the large wheels it is preferable to provide an antifriction bushing or removable hearing as 20 shown in Figs. 14 and 16 which may be made of oil soaked wood or any other antifriction material, and these bearings are secured in place on the inside of the rim 2 and on the outside of the rim 2 by means of the clips 20 which are held in place by bolts 20, and the aperture 21 in the bush does not extend entirely therethrough thus providing an end thrust bearing for each of the pins 19 and 19 which can in connection therewith be so adjusted as to take up all lost motion and thus cause silent running of the wheel; these antifriction bearings and the light frames of the sails with canvas or other light weight sail material in connection therewith make possible the construction of a very strong, light and easy running feathering blade windwheel, which in connection with the governing mechanism above described is very sensitive in its governing qualities.

The method of pivoting the sails at their outer ends as is usually done throws all of the wind pressure on bearings that are extremely wide apart which causes the sails to spring and cause undue strains and friction on the sail pivots, thus causing rapid wear of the pivots and very seriously interfering with the governing of the speed of the wheel. To overcome these objectionable features I place the pivots at such distance from the ends of the sails as to give a sail surface outside of the pivots that is substantially equal to the surface between the pivots so that the wind pressure is practically balanced on the pivots with but slight tendency to spring the sails, with the further advanta ge of having the pivots closer together, thus giving greater strength to resist the tendency to spring under the heavier wind pressures; I also place these pivots in the longitudinal centerline of the sail with the longitudinal centerline of the pivots in the plane of the sail surfaces. With the sails thus nicely poised upon the pivots there is but little force required to governingly' actuate them thus making it possible to govern the speed of the wheel very closely.

In the very large wheels the spokes 4 may be made in detachable parts as shown in Figs. 6 and 7 and connected together in operative form by means of the turnbuckles 15 as shown in Fig. 8, and if at any time it may, be found convenient or desirable to have but two instead of four united it is readily done by simply making the spokes in the form shown in Fig. 7 of a length suitable to the size of the wheel and secure the ends thereof to the rim of the wheel as shown in Fig. 5.

Fig. 21 represents a group of four spokes made integral from two pieces of wire or rods preferably by means of the electric welding process, the enlargements 30 midway between the bends or loops 15 are caused by the process of welding and are purposely made unusually large so as to provide a substantial means of attachment to the hub of the wheel, this attachment of the spokes to the hub of the wheel is made substantially as shown in Figs. 17 and 32 in which 31 is a portion of the wheel hub and 31 is a special clamping piece or washer which is provided, on its clamping side, with the groove 30 and the cavity 30 for securing the spokes in place, a corresponding groove and cavitv being formed in the coacting part of the hub which is also provided with an aperture or cavity for the reception of the lug 31 which assists in holding the clamping piece 31 immovable when the nut is tightened on the bolt 27 with the spoke in place between the hub and clamping piece as shown in Fig. 17, the enlargement 30 being made for a tight fit in the cavity 30 thus providing a very rigid and enduring means of attachment of the spokes to the hub of the wheel.
