Background of Invention

1. Field of the Invention: This invention relates to the field of wind-driven turbines.

2. Description of the Prior Art: With the ever increas¬ ing demand for energy and the inevitability of man eventually consuming all of the fossil fuel, i.e., particularly petroleum, science is obviously searching for substitutes for petroleum- consuming machinery. Therefore, electricity is being consi¬ dered for eventually powering machinery that heretofore was deemed unfeasible. Accordingly, various means for generating electrical energy are presently being explored, among these are various wind-powered apparatuses toward which the present invention is addressed. Numerous and varied configured wind turbine have heretofore been conceived and developed. In fact, applicant is aware of the following U.S. patents pertaining to such various apparatuses; Patent No. 372,300 to Chubbuck; Patent No. 1,460,114 to Shelton; Patent No. 1,463,924 to Ozaki; Patent Nos. 1,523,295 and 1,574,171 to Ryan; Patent No. 1,677,745 to Bonetto; Patent No. 1,812,400 to Gilley; Patent No. 1,974,008 to Biehn; Patent No. 2,059,356 to James; Patent No. 2,169,149 to Johanson; Patent No. 3,721,290 to Butler; and Patent No. 4,019,828 to Bunzer. None of the above patents dis¬ close or suggest the present invention.

Summary of the Invention The present invention is directed towards overcoming the disadvantages and problems relative to previous wind turbines. The concept of the present invention is to provide a wind tur¬ bine means which includes a turbine wheel means and a shroud means for partially covering the turbine wheel means to vary the effect of changing wind conditions on the turbine wheel means. For example, the present invention may provide a turbine wheel which includes a housing for enclosing the electrical

generating apparatus, and track structure which engages and rotatably drives the electrical generating apparatus, e.g., a generator or the like through suitable coupling structure. Shroud structure, is disposed in operable exterior proximity with the turbine wheel for varying the effectiveness of the wind as it is acting upon the turbine wheel, i.e, in infinite variable stages commensurate with the changing velocity of the wind. The speed of the turbine wheel is automatically con¬ trolled so as to remain substantially constant throughout a wide variance of natural wind velocity and irrespective of the direction of the wind.

More specifically the shroud structure or deflector apparatus thereof, includes integrally attached primary and secondary quadrant member diagonally disposed one from the other and converging at the vertically axis of the turbine, wheel. The deflector has a normal position which corresponds to minimal wind velocity conditions, a retard position which corresponds to strong wind velocity conditions, and infinite variable positions therebetween. The primary quadrant member includes primary baffler means for precluding direct impingeme of the wind with the convex surfaces of the individual vanes o the turbine wheel which occupy the forward facing semicircle o the turbine wheel when the deflector is in a normal position. The secondary quadrant member includes an air scoop for scoopi and directing the wind inwardly toward a portion of the rearwa semicircle of the turbine wheel when the deflector is in a normal position. Thus, the air scoop causes the wind to ad¬ vantageously impinge the concave surfaces of those individual vanes which occupy at least a portion of the rearward semi¬ circle of the turbine wheel, i.e., when the wind velocity is minimal.

The device also includes control structure for sensing changes in the wind velocity and effectively controlling the position of the deflector which is operatively responsive to the control structure, i.e., in moving to the various positions alluded to above so as to have varying degrees of effect in controlling the speed of the turbine wheel.

It is anticipated that the wind turbine of the present in¬ vention will be used for infinite purposes, i.e.,

that it might be desirable to generate electrical energy. How¬ ever, the present invention is anticipated as being especially adaptable to various vehicles bσth fast-moving vehicles, e.g., trains, trucks, buses, etc., as well as slow-moving vehicles, e.g., farm tractors, hay mowers, combines, boats, barges, house-boats, etc. Also the present invention may be used on stationary structures, e.g., residential dwellings, mobile homes, multi-story apartment and commercial buildings, on specially constructed foundations the height and diameter would be limited only by practicality. Additionally, many long roofed vehicles could use a plurality of wind turbines of the present invention, i.e., station wagons, trailer trucks, buses, house trailers, motor homes, mobile homes, trains, etc.

The shroud may be removed from the turbine wheel if de¬ sired, but under normal wind conditions, on stationary struc¬ tures and slow moving vehicles the shroud remains in a rela¬ tively normal position, but in high velocity winds and on fast moving vehicles the shroud moves to its retard position to con¬ trol the speed of the revolving turbine wheel and also act to shield and protect the turbine wheel means.

Description of the Preferred Embodiments

A first embodiment of the wind turbine means of the present invention is shown in Figs. 1-19 of the drawings and identified by the numeral 11. The wind turbine means 11 of the present invention is shown in Figs. 1 and 2 of the draw¬ ings- in a somewhat rudimentary or partially developed condi¬ tion in which it is, nonetheless, intended to be powered by the wind for generating electrical energy. Fig. 1 shows one of th.e wind turbine means 11 suitably configured to the roof structure of the tractor section 12a of the semi-truck trailer unit and several of the wind turbine means 11 suitably con¬ figured to the roof structure of the trailer section 12b all of which may individually be utilized in different configurations which will be fully disclosed as the specification proceeds.

In Fig. 2 of the drawings it may clearly be seen that the wind turbine means 11 generally comprises wind rotatable tur¬ bine wheel means 13 having a turbine 13' with numerous vanes 15, which may individually be designated as 15a, 15b, 15c, etc., defining at least in part the periphery thereof. Each of the vanes terminates inwardly at a concentrically disposed cir¬ cular wall 17. From Fig. 3 of the drawings it may be seen that the upper and lower ends of the vanes 15 terminate at respec¬ tive upper and lower flange members 19, 21.

Additionally, a closure disc 23 is included as part of the turbine wheel means 13 and as shown in Fig. 3, the perimeter margin thereof, as at 25, is fixedly joined to the top of the circular wall 17. The interior of the disc 23 and the circular wall 17 jointly establishes in part a circular enclosure,

27, for housing certain electrical apparatus. The electrical apparatus at least includes electric means, as at 28, and as clearly shown in Fig. 6 of the drawings, for -converting mechan cal energy to electrical energy, i.e., and alternator 29 or th like suitably coupled to rectifier means 31 and voltage regula tor means 33. It should be understood that the electric means 28 is intended to charge storage battery means 35 which in all probability will be located remotely from the wind turbine means 11, i.e., it is not intended that the storage battery means 35 be physically located within the enclosure 27.

More specifically, the storage battery means 35 may simply be the conventional battery used in any vehicle for starting the engine, etc., or it may take on much more elabora meaning. For example, the storage battery means 35 may consti tute a rather large bank of batteries conveniently located on the trailer section 12b for perhaps powering an integral re¬ frigeration unit. Thus, perishables stored within the trailer 12b may be provided with proper temperature control or cold storage even while the trailer 12b may be disconnected from the trailer section 12a. The storage battery means 35 will constantly be charged by the electrical means 28 as the wind i blowing. It should be understood that the present invention is not intended to be limited to specifying the particular wor the storage battery means 35 may accomplish since it is antici pated that the present invention may be employed in infinite situations or anywhere that the generation of electrical energ may be desirable.

The turbine 13' also includes a concentric circular track member 37, as best viewed in Figs. 3 through 5 of the drawings, disposed subjacent the vanes 15 for rotation therewith. The wind turbine wheel means 13 also includes sheave means 39 dis¬ posed within the circular enclosure 27 and having means, e.g., endless belt means 41 or the like, for operative engagement wi the circular track member 37. The sheave means 39 is coupled the electric means 28 whereby electrical energy is generated a the wind rotatably drives the turbine 13' while the sheave mea 39 is being rotatably driven by the circular track member 37. In Fig. 2 et al of the drawings the direction of the wind is intended to be illustrated by a plurality of arrows 43. Also,

-7 - the direction of rotation of the turbine 13' is indicated by an arrow 45. Further, the direction of rotation of the sheave means 39 is indicated in Fig. 5 of the drawings by an arrow 47.

The power transmitting medium 42 from the rotating tur¬ bine wheel 13' to the batteries is made up of the sheave 39, endless belt 41, crank membe 69, compression spring 67, bearings 73 and 77, and the electrical means 28. Although there is only one power transmitting unit 42 shown in the drawings, there may be as many as space in the enclosed area 27 will allow, i.e., three, more or less.

From Fig. 3 of the drawings it may be seen that the track member 37 is integrally attached to the lower flange member 21 while the lower portion of the track member 37 includes an inwardly directed flange member 49.

The wind turbine wheel means 13 also includes frame means constituting a plate- ike member or floor 51 for the circular enclosure 27 and an upper plate-like member 53 establishing a roof-like arrangement for the turbine 13'. The plate-like members 51, 53 are rigidly maintained in their spaced-apart distance by a plurality of vertical support members 55.

The turbine 13' includes a hub 57 which is fixedly at¬ tached to rotatable shaft 59 by a set screw 61 or the like. The shaft 59 is journaled to the plate-like members 51, 53 in a suitable manner as by bearing 63 or the like.

Additionally, the vanes 15 preferably are protected from being damaged by birds or other objects by providing suitable guard structure, e.g. , hardware fabric 65 or the like, there¬ about.

The sheave means 39 frictionally engages the track member 37 and is yieldably urged toward the track member 37 by helical compression spring means 67 or the like. The sheave means 39 is swingably mounted to the plate-like member 51 by incorporating a crank member 69. A lower arm 71 of crank member 69 is suitably journaled- to the plate-like member 51, as by bearing 73, and the sheave mean 39 is suitably journaled to an upper arm 75 of crank member 69,

as with a bearing 77 or the like. ^' Therefore, since the spring 67 is arranged, as shown in Fig. 5, to pull the upper arm 75 toward the track member- 37 (in the direction of an arrow 68), the sheave means 39 is yieldably urged toward the track member 37 for frictional engagement therewith. Pre¬ ferably, the thickness of the.endless belt 41 is such that the belt 41 extends beyond the periphery of the sheave means 39 for engagement with the track member 37.. Although the track member 37 may, if desired, include internal gear teeth which meshingly engage external teeth on the sheave means 39, thus negating the belt 41.

Particular attention is now directed toward Fig. 6 of the drawings where it may be seen that the alternator 29 is coupled to the rectifier means 31 through a conductor 79 with the al¬ ternator 29 being suitably grounded through a conductor 81. Additionally, a conductor 83 couples the rectifier means 31 with the voltage regulator means 33 which in turn is suitably coupled to the storage battery means 35 as indicated by a conductor 85.

From Figs. 7-19 of the drawings it may be seen that the wind turbine means 11 of the present invention preferably in¬ cludes shroud means 87. It should be understood that the shroud means 87 as shown in Figs. 7-19 has been removed from the turbine wheel means 13 so as to more clearly depict the structure peculiar thereto. However, the shroud means 87 is intended to be disposed in operable proximity with selectable ones of the vanes 15, i.e., the shroud means 87 simply fits down over the upper plate-like member 53 with certain-.structure thereof depending downwardly in a confronting arrangement with certain of the vanes 15 in a manner to be fully disclosed as the specification proceeds. The shroud means 87 may option¬ ally be utilized for automatically varying the effectiveness of the wind as it is acting upon the turbine wheel 13. The effectiveness of the shroud means 87 is in infinite variable stages commensurate with the changing velocity of

pivot means 101, for pivotally joining the deflector means 89 and the tail fin means 91 one to the other and for individual pivotal movement about their coextending vertical axis 95. More specifically, the deflector means 89 is provided with a socket 103, while the tail fin means 91 includes an umbonated member 105 which is pivotally received within the socket 103, i.e., the umbonated member 105 preferably is integrally formed -with the tail fin means 91 or at least they move in unison.

From Figs. 13-19 of the drawings it may clearly be seen that the wind turbine means 11 also includes limit means, as at 107, for establishing limits to the relative pivotal move¬ ment of the deflector means 89 and the tail fin means 91. More specifically, the primary quadrant member 97 includes a pair of main support arms 109, 111 which suitably support a web or plate-like member 113. Similarly, the secondary quad- drant member 99 indues a pair of main support arms 115, 117 which suitably support a web or plate-like member 119.

The limit means 107 includes providing the umbonated member 105 with an arcuate groove, as at 121 in Figs. 13-15, for receiving a protuberance 123 or inwardly directed exten¬ sion of the arm 115, i.e., the other three arms 109, 111, 117 terminate inwardly at the socket 103 while the protuberance 123 extends into the socket and is received in the arcuate groove 121. The length of the groove 121 is calculated so as to enable the limit means 107 to be effective in limiting the relative movement of the deflector means 89 and the tail fin means 91 to substantially 90°.

From Fig. 8 et al of the drawings it may clearly be seen that the control means 93 also includes at least principal bias means, as at 125, for yieldably biasing the deflector means 89 and the tail fin means 91 one to the other. The principal bias means 125 must be overpowered in achieving relative move¬ ment of the deflector means 89 and the tail fin means 91.

Figs. 3 and 16 of the drawings clearly show the upper plate-like member 53 being provided with an upwardly directed socket 131 which is defined by a circular wall 133 having a

transversal threaded aperture 135 provided therein for threadedly receiving a lock bolt 137 or the like therein. Figs. 12 and 16 show that the umbonated member 1Q5 is provided with an annular groove 139 which is adapted for alignment with the threaded aperture 135. The umbonated member 105 is pivotally received in the socket 131 while the lock bolt 137 extends in¬ to annular groove 139, thus locking the shroud means 87 with the turbine wheel means 13, i.e., as stated above, the turbine 13' and the shroud means 87 are independently free to rotate 360° about their axis 95. Thus the lock bolt 137 merely pre¬ vents lifting the shroud means 87 from the socket 131.

From Fig. 11 of the drawings it may clearly be seen that an outer end 141 of the principal bias means or torsion spring 125 engages the main support arm 115. Fig. 12 shows an inner end 143 of the spring 125 engaging the tail fin means 91. The tail fin means 91 is provided with a bore 145 for receiving the inner end 143. Accordingly, when viewing the deflector means 89 from above, as shown in Fig. 8 of the drawings, the principal bias means or torsion spring 125 urges the deflector means 89 clockwise (or in the direction of an arrow 147) with respect to the tail fin means 91. In other words, the prin¬ cipal bais means or torsion spring 125 must be overpowered in achieving counterclockwise movement of the deflector means 89 with respect to the tail fin means 91.

From the above disclosure it should now be readily under¬ stood that the deflector means 89 has a normal position as shown in Figs. 8, 13, 15, and 18 of the drawings. The normal position of the deflector means 89 corresponds to minimal wind velocity conditions. The deflector means 89 also includes a retard position characterized by the numeral 89 having the letter R suffix position as best shown in Figs. 14 and 19 of the drawings and which corresponds to strong wind velocity conditions. It should now be apparent that the deflector means 89 also includes infinite variable positions between the normal position and the retard position, i.e., depending upon the length of the arcuate groove 121 which as above disclosed pprreeffeerraabbllyy ppeerrmmiittss 9900 rreellaattiivvee mmoovvement of the deflector means 89 and the tail fin means 91.

OΛ.PI

From Figs. 2 and 7-10 of the drawings it may be seen that the primary quadrant member 97 includes primary baffler means 149 for precluding direct impingement of the wind with the convex surfaces 129 of those individual vanes, e.g., the vanes 15k, 15m, 15n Ohow in Fig. 2) or those vanes which occupy the forward facing semicircle of the turbine 13' and when the deflector means 89 is in the normal position as shown in Fig. 8, i.e., Fig. 8 should mentally be superimposed over Fig. 2 in order to visualize the actual prevailing conditions.

From Fig. 8 of the drawings it may clearly be seen that the primary baffler means 149 includes a plurality of min- baffle plates 151, which may individually be designated as 151a, 151b, 151c, etc. Each of the mini-baffle plates 151 have a predetermined arcuate shape and degree of pitch. The mini-baffle plates 151 are arranged for progressively changing the direction of the wind whereby the wind impinges, either directly or indirectly, the concave surfaces 127 of all those individual vanes (15a, 15b, 15c, 15k, 15m, 15n or those vanes which occupy the forward facing semicircle of the turbine 13' when the deflector means 89 is in the normal position.

The respective upper ends of the plurality of mini-baffle plates 151 are fixedly attached to the arcuate marginal portio of the pie-shaped web 113 in any well-known manner as by weldi or the like. The primary baffle means 149 also includes an arcuate formed reinforcement member 153 for supporting the lower ends of the plurality of many baffle plates 151, i.e., the respective lower ends of the plurality of mini-baffle plates 151 are fixedly attached to the reinforcement member 153 in any well-known manner as by welding or the like.

The control means 93, or more specifically the principal system 93a thereof, in addition to the previously mentioned principal bias means or torsion spring 125, includes a plurali of progressively operable wind-flap elements 155 which may individually be designated as 155a, 155b, 155c, etc., as clear shown in Figs. 7-9 of the drawings. The wind-flap elements 15 are pivotally attached, as with a plurality of pivot pins 158, to the primary quadrant member 97 for pivotal movement about their respective vertical axis with the wind-flap elements 155

having independently operable retracted and extended positions. More specifically, the wind-flap elements 155 are shown in solid lines in Fig. 8 in their retracted positions and in which they are simply characterized by the numerals 155 having the appropriate letter suffix. Additionally, the wind-flap elements 155 are shown in Fig. 8 in broken lines in their respective extended positions in which they are characterized by a numeral 155 and the appropriate letter suffix and also being further characterized by prime suffixes.

The principal system 93a also includes a plurality of mini-bias elements 157 which are respectively attached to the plurality of wind-flap elements 155 as best show in Fig. 8 of the drawings for yieldably biasing the wind-flap elements 155 toward the respective retracted positions thereof (as shown in solid lines) . The wind-flap elements 155 are pro¬ gressively moved to their respective extended positions (as shown in broken lines) as the velocity of the wind increases. The extended wind-flap elements thusly, are effective in re¬ acting with the increasing wind velocity to overpower the principal bias means or torsion spring 125 as the deflector means 89 gradually moves toward the retard position 89R as best shown in Figs. 14 and 19 of the drawings.

The secondary quadrant member 99 includes secondary baffle means 159 for shielding at least a portion of the concave sur¬ faces 127 of the vanes 15a, 15b, 15c or stated another way, for shielding the concave surface 127 of those individual which occupy the forward facing semicircle of the turbine 13' when the deflector means 89 is moved toward the retard position 89R as clearly shown in Figs. 14, 19 of the drawings.

It should be understood that the just-mentioned secondary baffle means 159 may incorporate several embodiments, e.g., it might simply be established by a vertically arrange arcuate formed plate-like member 161 which depends downwardly from adjacent the pie-shaped web or plate-like member 119. However.,

the secondary baffle means 159 preferably incorporates air-scoo means as best shown in Fig. 8 of the drawings and ^' characterized therein by the numeral 163. ^'

The air scoop means 163 includes the vertically disposed arcuate plate-like member 161 alluded to above. The air-scoop 163 scoops and directs the rushing wind inwardly toward a por¬ tion of the rearward semicicrcle of the turbine 13' when the deflector means 89 is in the normal position thus causing the wind to advantageously impinge the concave surfaces 127 of the vanes 15d, 15e, and 15f. Stated another way, the air-scoop means 163 directs the wind toward the concave surfaces 127 of those individual vanes which occupy at least a portion of the rearward semicircle of the turbine 13', i.e., here again it should be understood that Fig. 8 is intended to be super¬ imposed over Fig. 2 in order to fully understand the function o the air scoop means 163.

The air scoop means 163 may, if desired, be fixed in an optimum position for scooping in the wind toward the vanes 15d, 15e, 15f when the deflector means 89 is in the normal position. However, the air scoop means 163 preferably includes air-scoop pivot means 165 for pivotally attaching the arcuate plate-like member 161 to the shroud means 87. Therefore, the air-scoop means 163 preferably is pivotally movable between an open posi¬ tion shown by the numeral 163 in Fig. 8 and a closed position shown by the numeral 163 having the letter C suffix in Fig. 10 of the drawings, and having infinite variable positions there¬ between.

The shroud means 87 preferably includes a horizontally disposed arcuate formed support member 167 (Fig. 8) which is rigidly joined to the outer ends of the main support arms 115, 117 by incorporating a pair of vertically disposed support members 169, i.e., the vertical support members 169 are inter¬ posed between the main support arms 115, 117 and the arcuate formed support member 167 and are fixedly attached thereto as by welding or the like.

The control means 93, as previously mentioned, includes a secondary system 93b for simultaneously controlling the pivotal

-15- movement of the air scoop means 163 between the just men¬ tioned open and closed positions as the deflector means 89 is caused to move between the normal and retard positions 89, 89R in the manner as previously described.

From Figs. 8-10 of the drawings it may clearly be seen that the secondary system 93b includes mechanical linkage, generally as at 171, for interconnecting the tail fin means 91 and the air scoop means 163 one with the other. Therefore, movement of the deflector means 89 from the normal position as shown in Figs. 8 and 18, to the retard position as shown in Figs. 14 and 19, is simultaneously effective in causing the air scoop means 163 to be moved from the open position thereof, as shown in Fig. 8, to the closed position 163c thereof, as shown in Fig. 10.

The mechanical linkage means 171 preferably includes a rather stiff but nonetheless flexible elongated wire-like member 173 which is slidably received within a typical sheave 175 which is fixedly attached to the plate-like member .119 in any well-known manner, i.e., as with a pair of typical clamps 177 and screw fastener means 179.

The outer end, as at 181, of the wire-like member 173 is pivotally attached to the plate-like member 161 in any conventional manner. The other end, as at 183, of the wire¬ like member 173 is pivotally attached to the tail fin means 91 in any well-known manner, i.e., as with swivel-eye means 185 or the like. The swivel-eye means 185 is attached to the tail fin means 91 at a predetermined position (or a calculated space distance from the vertical axis 95) so that counter¬ clockwise movement (as viewed in Fig. 8) of the deflector means 89 is effective in enabling the mechanical linkage 171 to move the air-scoop means 163 to the closed position 163C, as shown in Fig. 10.

The secondary system 93b may optionally include secondary bias means 187 (as shown in Fig. 8 of the drawings) for yieldably urging the plate-like member 161 toward the open position. It will be understood by those skilled in the art that the incorporated (optional) secondary bias means 187 yieldably urges the plate-like member 161 to the position shown in Fig. 8. Therefore, the mechanical linkage means

-16- may, in this instance, simple include a flexible cable, i.e., in lieu of the rather stiff wire-like member 173, the sheave 175, and the clamps 177. In other words, tension applied to the flexible cable closes ^' the air scoop means while the secondary bias means 187 opens the air scoop means 163.

From the above disclosure it should now be appreciated that the changing wind direction acting upon the tail fin means 91 causes the deflector means 89 to pivot about the vertical axis 95 (or move within the socket .131 so that the deflector means 89 will always be properly oriented in its azimuthal datum-plane with, respect to the wind direction in like manner as depicted in Fig. 8, i.e., the arrows 43 in¬ dicate the direction of the wind. Therefore, the tail fin means 91 will be aligned by the direction of the wind, always be trailing, or disposed so as to substantially bisect the rearward semicircle of the turbine 13'. In other words, a change in wind direction causes the tail fin 91 to shift which carries the deflector means 89 along with it.

During minimal wind velocity, the deflector means 89 re¬ mains substantially as depicted in Fig. 8, i.e., in the normal position. However, as the wind velocity increases, the de¬ flector means 89 gradually shifts counterclockwise. The tail fin means 91 has a rather large surface, thus it remains in the position shown. However, the wind acting upon the wind- flap elements 155 is effective in overpowering the principal bias means or torsion springs 125 to achieve the relative counterclockwise movement of the deflector means 89 relative to the tail fin means 91.

More specifically, as the wind increases in velocity and greater degree of counterclockwise movement of the deflector means 89 is achieved, the wind-flap element 155b is brought around into confronting engagement with the wind (i.e., more perpendicular to the direction of the wind) which causes it to move to the extended position 155b' and the wind-flap element 155c subsequently is extended in like manner as the 90° shift of the deflector means 89 is achieved. The limit means 107, of course, prevents further shifting of the deflector means 89 with respect to the tail fin means 91.

It should also be readily understood that as the primary quadrant member 97 moves ^' counterclockwise, as from the position shown in Fig. 8, the convex surfaces 129 of the vanes 15k, 15m and 15n are now becoming exposed to direct impingement with the wind which tends to rotate the turbine 13' ^' in a direction opposite to. the arrow 45, thus- preventing excessive speed of the turbine wheel means 13.

The air-scoop means 163 is gradually closing as the de¬ flector means 89 shifts counterclockwise which, of course, ne¬ gates the effectiveness thereof in graduating degrees, i.e., also tending to cause the turbine 13' to rotate at a lower speed. In addition, as the deflector means 89 rotates counter¬ clockwise the secondary baffle means 159 gradually comes into play or precludes direct impingement of the wind upon the concave surfaces 127 of the forward facing vanes 15a, 15b, 15c which also tends to slow down the speed of the turbine 13'.

It may be desirable to incorporate adjustment means for the control means 93. Accordingly, certain structure well known to those skilled in the art may be included for selectively ad¬ justing the tension on the principal bias means or torsion spring 125, and/or the tension on the mini-bias elements 157, and/or the tension on the secondary bias means 187. Such ad¬ justments means is deemed mundane and is, therefore, not shown in the drawings but is, of course, anticipated and when de¬ sirable it may be accomplished in accordance with the latest state of the art.

A second embodiment of the wind turbine means of the present invention is shown in Figs. 20-23 of the drawings and identified by the numeral 2.11. The wind turbine means 2.11 is shown mounted on a building B (see, in general, Fig. 20) and can be mounted on a building B (see, in general, Fig. 20) and can be mounted on residential dwellings, especially constructed foundations or skeletal frame structures, ships, barges, multistory apartment and commercial buildings, round football and baseball stadiums, etc. It could have a diameter limited only by practicality, since it is supported by a firm foundation directly beneath the turbine wheel vanes and not by a relatively small centrally located axle or hub. Various components, elements and parts of the wind turbine means 2.11 are substan-

O.MPI

tially identical to corresponding components, elements and parts of the wind turbine means 11 and will be identified by the same basic numerals heretofore used in conjunction wit the description of the wind turbine means 11. ith the additio of the numerical prefix "2," and the above description of the wind turbine means 11 should be consulted for a more detailed explanation of the construction and operation thereof. Thus, the wind turbine means 2,11 includes a turbine wheel means 2. defined by numerous vane ^' s ^' 2.15 with each vane 2.15 having con cave surface 2.127 and a convex surface 2.129 and terminating inwardly at a concentrically disposed circular wall 2.17, up¬ wardly at an upper flange member 2.19 and downwardly at a low flange member 2.21 Csee, for example, Figs. 22 and 23); and includes a shroud means 2.87 defined by a deflector means, a tail fin means 2.91 and a control means see, for example Fig 1 and 2). A pair of endless, circular tracks ^' or rails 2.189 are attached to the bottom of the turbine wheel means 2.13 (see Fig. 22). A plurality of wheel 2.191 for engaging the rails 2.195 are rotatably attached to the building B whereby the wheels 2.197 support the shroud means 2.87. The wheels 2.197 are preferably attached to the building B by way of an upper annular plate member 2.199 and a lower annular plate member 2.201 which are fixedly attached to the building B in any manner apparent to ^" those skilled in the art and which als serve to partially enclose or house the turbine wheel means 2.13 (see, in general Fig. 22). A screen or other hardware fabric 2.65 preferably extends between the upper and lower annular plate member 2.199, 2.201 as shown in Fig. 22 to furt enclose the turbine wheel means 2.13 and prevent the vanes 2. from being damaged by birds and the like. Brackets 2.203 may be attached to the lower annular plate member 2.201 and t the shafts 2.193 (with the shaft 2.193 being rotable relative to the brackets 2.203) to give added support to the wheels 2.191 and shafts 2.193 (see Fig. 22). When wind strikes the vanes 2.15, causing the turbine wheel means 2.13 to rotate, t rails 2.189 will glide upon the. wheels 2.191 thereby causing the wheels 2.191 and shafts 2.19.3 to rotate. The rotation of the shafts 2.193 can then be utilized in any manner such as t produce electrical energy by applying rotary motion to one or

, ^f

-19- more alternators 2.29,. etc., as will be apparent to those skilled in the art. ^' Further, it should be noted that rotation of the shafts 2.193 may be utilized to rotate flywheel means (not shown) for storing energy and/or for braking the rotation of the turbine wheel means 2.13 in any manner which should now be apparent to those skill in the art. Additionally, it should be noted that wheel ^' s 2.191 are preferably shiftably mounted relative to rails 2.189 by suitable means, as for example by utilizing and spline-type mounting of the wheels 2.191 on the shafts 2.193 so that the wheels 2.191 may be shifted to disengaged positions (shown in broken lines in Fig. 23) relative to rails 2.'189 by suitable means well known to those skilled in the art, as for example, electronically, or if desired, manually, whereupon the corresponding alterna¬ tors 2.29 will not be driven. Also, if desired, the wheels 2.191 may be fixed to shafts 2.193 and the shafts 2.193 shifted by suitable means, as a lever (not shown) or other means well known to those skilled in the art to disengage the wheels 2.191 from the rails 2.189. Thus, when the wind velocities are very low and there is a need to reduce friction to a mini¬ mum, a specified maximum number of the wheels 2.191 may be disengaged, as for example up to 1/2 of the wheels or every other one. As the speed of the turbine wheel means 2.13 in¬ creases to a point that the maximum capacity from the engaged alternators 2.29 is obtained, then the other wheels 2.191, with corresponding alternators 2.29 could be engaged, one by one, as the alternators 2.29 reach their maximum generating capacity. As each additional wheel 2.191 is engaged it would tend to slow the turbine wheel means 2.13 rotation. After all wheels 2.191 are engaged and all alternators 2.29 reach their maximum generating capacity, then the flywheels (not shown) suitably coupled to shafts 2.193 would be engaged one by one. As each flywheel reaches its maximum rpm another would engage.

The deflector means of the shroud means 2.87 is sub¬ stantially identical to the deflector means 89 of the shroud means 87 of the wind turbine means 11 and includes a primary quadrant member 2,97, a secondary quadrant member 2.99, a normal position, a retard position, and infinite variable

positions therebetween. The primary quadrant member 2.97 includes primary baffle means having a plurality of mini- baffle plates 2.151, etc. (see Figs. 21 and 23). The secondary quadrant member ^' 2.99 includes secondary baffle means defined by an air scoop means 2.163, etc. (see Fig. 21).

The tail fin means 2.91 of the shroud means 2.87 is substantially identical to the tail fin means 91 of the shroud means 87 of the wind turbine means 11 and is pivotally joined to the deflector means by pivot means 2.101, etc. The wind turbine means 2.11 also includes limit means which may be substantially identical to the limit means 107 of the wind turbine means 11. On the other hand, the limit means may merely consist of peg members 2.205 extending upwardly from the deflector means as shown in Figs. 20 and 21 for engaging the tail fin means 2.91 to limit relative movement of the deflector means and the tail fin means 2.91 to sub¬ stantially 90° as will now be apparent to those skilled in the art.

The control means of the shroud means 2.87 is substan¬ tially identical to the control means 93 of the shroud means 87 of the wind turbine means 11 and includes a primary system and a secondary system. The primary system includes a principal bias means 2.125 and a plurality of wind-flap ele¬ ments 2.155. The secondary system includes mechanical link¬ age 2.171 having a wire-like member 2.173 slidably received in a sheave 2.175. The outer end of the sheave 2.175 is fixedly attached to the deflector means by way of a clamp 2.177. The inner end of the sheave 2.175, rather than being fixedly attached to the deflector means as is the inner end of the sheave 175 of the wind turbine means 11, may be movabl attached to the deflector means by way of a member 2.207 fixedly attached to the deflector means and having a curved slot 2.209 to which the inner end of the sheave 2.175 is slidably attached by a pivot pin 2.211 or the like see Fig. to allow the sheave 2.175 to form a gradual bend when the air-scoop means 2,163 is in an open position as shown in soli lines in Fig. 21 in a manner as should now be clear to those skilled in the art.

A third embodiment of the wind turbine means of the pres

invention is shown in Figs. 24-27 of the drawings and identified by the numeral 3.11. The wind turbine means 3.11 is shown mounted on a building B and can be mounted on resi¬ dential dwellings, specially constructed foundations or skeletal frame structures ^' , ships, barges, multi-story apart¬ ment and commercial buildings,' ^" round football and baseball stadiums, etc. It could have a diameter limited only by practicality, since it is supported by a firm foundation directly beneath the turbine wheel vanes and not by a rela¬ tively small centrally located axle. It would be especially suitable for multi-story structures so that a complete unit could be a part of each floor (story) . The building design would, preferably, be a cylindrical or five or more sided regular polygon. As on most multi-story buildings, there is a three or four foot, more-or-less, crawl space between each floor for water pipes, electric wire and cables, hot and cold ducts, etc. Housing for the turbine wheel could be constructed as part of the building, on the outer wall adjacent to this crawl space between each floor. Various components, elements and parts of the wind turbine means 3.11 are substantially identical to corresponding components, elements and part of the wind turbine means 11 and the wind turbine means 2.11 and will be identified by the same basic numerals heretofore used in conjunction with the above description of the wind turbine means 11, 2.11 with the addition or substitution of the prefix "3." and the above description of the wind turbine means 11, 2.11 should be consulted for a more detailed explanation of the construction and operation thereof. Thus, the wind turbine means 3.11 includes a turbine wheel means 3.13 defined by numerous vanes 3.15 with each vane 3.15 having a concave sur¬ face 3.127 and a convex surface 3.129 and terminating inwardly at a concentrically disposed circular wall 3.17, upwardly at an upper flange member 3.19 and downwardly at a lower flange member 3.21 see Figs. 26 and 27) and includes a shroud means 3.87 defined by a deflector means and a control means. The turbine wheel means 3.13 includes rails 3.189 for coacting with wheels 3,191 which are attached to shafts 3,193 and which

_ O. PI

are supported by the building B whereby the turbine wheel means 3.13 is supported and whereby rotation of the turbine wheel means 3.13 will rotate the wheels 3.191 and shafts 3.193 whereby electrical energy can be produced by way of an alter¬ nator 3.29, etc. (see Figs. 26 and 27). If desired, the wheels 3,191 may be shiftably mounted relative to rails 3.189 in the manner and for the purpose heretofore described relative to wheels 2.191 and rails 2.189. The shroud means 3.87 includes rails 3.195 for coacting with wheels 3.197 whic are supported by upper and lower plate members 3.199, 3.201 that are attached to the building B whereby the shroud means 3.87 is supported and whereby the turbine wheel means 3,13 is partially enclosed Csee, in general, Fig. 26). A screen or other hardware fabric 3.65 preferably extends be¬ tween the upper and lower plate members 3.199, 3.201 to further enclose the turbine wheel means 3.13 and protect the vanes 3.15 from damage, etc. Csee, ^' in general, Fig. 26).

The deflector means of the shroud means 3.87 is sub¬ stantially similar to the deflector means 89 of the wind turbine means 11 and includes a primary quadrant member 3.97, a secondary quadrant member 3.99, a normal position, a retard position, and infinite variable positions therebetween. The primary quadrant member includes primary baffle means having a plurality of mini-baffle plates 3.151, etc. (see, in general, Fig. 25). The secondary quadrant member 3.99 include a secondary baffle means defined by an air scoop means 3.163, etc. (see, in general, Fig. 25).

The control means causes the deflector means to rotate on the wheel 3.197 in response to the wind condition at the wind turbine means 3.11. Thus, the control means includes a princi pal system which may consists of one or more electric motors 3.213 drivably coupled to the deflector means in any manner apparent to those persons skilled in the art for selectively causing the. deflector means to rotate on the wheel 3.197, such as by being fixedly attached to one or more of the wheels 3.19 to cause the wheels 3.197 to rotate to thereby cause the rails 3.195 and the entire deflector means to rotate, ^' in which case

the wheel 3.197 may have gear teeth along its periphery and the rail 3.195 may include coacting gear teeth (see, in general, Fig. 26). The control means also causes the air scoop means 3.163 to move between its open position and its closed position in response to the wind conditions at the wind turbine means 3.11. Thus,- the control means includes a secondary system which may consist of an electric motor 3.215 drivably coupled to the air scoop means 3.163 in any manner apparent to those skilled in the art such as by way of a rack-and-pinion gear means 3.217 well known to those skilled in the art for causing the air scoop means 3.163 to move be¬ tween its open position and its closed position C ^see Figs. 25 and 26) . The pinion 3,218 of rack and pinion gear means 3,217 is mounted on. the shaft (not shown) of motor 3.213 which motor is pivotally mounted by suitable means from the shroud 3.87. The rack 3.219 of rack and pinion gear means 3.217 is pivotally attached at its outer end to an upstanding extension 3.220 fixedly attached to the upper edge of air scoop means 3.163. Air scoop means 3.163 is shown in the open position. Also, rack 3.219 is shown in solid lines in the position it is in when the air scoop means is in the open position. When rack 3.219 is moved to the dotted line position shown in Figs. 26 by the action of motor 3.213, the air scoop means 3.163 will be moved to a closed position.

The electric motors 3.213, 3.215 may be manually acti¬ vated to rotate the deflector means and/or open or close the air scoop means 3.163. Thus a person may monitor the wind conditions at the wind turbine means 3.11 in any manner apparent to those skilled in the art such as by way of typical and well known wind velocity, and direction measuring instruments (not shown) and may physically activate the electric motors 3.213, 3.215 to properly orient the deflector means with respect to the wind direction (i.e., with the deflector means oriented substantially as shown in Fig. 25 wherein the wind direction is indicated by arrows 3.43) and to properly open or close the air scoop means 3.163 with res- spect to the wind velocity, etc. On the other hand, the inventor envisions that the electric motors 3.213, 3.215 may be operated automatically in response to such typical and

"BUREA

well known wind velocity and direction measuring instruments in various manners which should now be apparent to persons skilled in the art.

Although the present invention has been described and illustrated with respect to various preferred embodiments there of, it is to be understood that it is not to be so limited since changes and modifications may be made therein which are within the full intended scope of the invention.
