erator directly connected to the apparatus, or
indirectly driven thereby by interposing suitable energy-storing means which may be drawn upon when the natural forces normally used are not available.
One of the primary objects of this invention is to provide a wind-operated turbogenerator that is mounted in unique fashion whereby to always be maintained in proper operative position in the direct path or" travel of the air currents beling utilized.
A yet further object of the instant invention is the provision of generating apparatus, wherein is included means for automatically controlling the amount of wind forceused; structure operated by the -change in the direction of wind travel for moving the generating apparatus to a position whereit will most efficiently operate; and a unique turntable for supporting all parts of the apparatus whereby they may be moved as a unit about a fixed center.
An evenfurth'er object of the invention is the contemplationof simple, durable and novel structure for accomplishing the above broad objects, and for embodying minor objects of the invention which will be specifically set down and described in the specification, referring to the accompanying drawings, wherein:
"Figure 1 is a top plan view of a wind-operated turbogenerator constructed in accordance with Jthe preferred form of this invention.

An understanding of the turbogenerator contemplated by this invention teaches that the same may be used in meeting power requirements for dwellings, groups of buildings, such as camps and farms, and even small towns or villages that are located in parts of the country where it is not uncommon for the Wind to blow steadily for long periods of time.'
While the drawings herewith illustrate the wind-driven rotor combined with an electrical generator and an air compressor, it must be understood that the force procurable from its rotation might be transmitted to any mechanism and harnessed for the accomplishment-of any type of work.
In describing the preferred embodiment of the invention, reference will be made to similar parts of the apparatus through the use of like reference numerals.
Since it is possible for wind to travel toward this generating apparatus from practically any direction, it becomes necessary toprovide means for easily accomplishing the proper positioning of the parts thereof, which are driven by the wind currents. The numeral 12 indicates a circular track, including a number of concentric paths formed of any suitable material that will support the weight and allow wheels 14 to freely ride thereover. In some instances track 12 is formed of concrete, reeniorced and maintained in spaced relation by a number of tie bars 16, which radiate from the axial center of track 12, as shown in Fig. 1. The axis of track 12, about which travels turntable 18, is indicated by the number 20 in Figs. 1, 2 and 6. Since radial movement on the part of turntable 18 is precluded by the holding power of the structure of axis 20, the same should be foundationed in concrete 22 and provided with a steel anchor 24, having an opening and cover 26 and 28 respectively to permit easy access to the chamber formed within foundation 22. As illustrated in Fig. 6, certain swivels and other parts forming a connection to compressed air storage tanks 0 30 are housed within the chamber formed at the axis.
As previously set down, turntable 18 moves along tracks 12 about axis 20. Connection from axis 20 to turntable 18 is set up through the medium of a number of tubular arms 32, as shown clearly in Fig. 1. The central arm 32 serves the purpose of conveying compressed air to tanks 30 when the hereinafter mentioned compressor is operating. Pipe 34 joins tanks 30 and central arm 32, a stuffing box 36 is employed to permit rotation of arm 32 about axis 20. A check valve 38 precludes back pressure and a by-pass 46 having a valve 42 interposed therein permits drawing off of compressed air from tanks 39 for the purpose of operating a later described turbine when conditions require such action.
One of the basic principles of this invention is built into the unique wind-driven rotor 44 which is shown in detail in Figs. 3 and 4. While it is possible to use any number of these rotors 44, it is preferred to employ even numbers and to ar range the same so that the direction of travel thereof will be equalizing to the entire apparatus. Each rotor is revolubly mounted on a horizontally disposed shaft 46, journaled in bearings 46 and supported high above turntable 18 by standards and braces 59 of any suitable nature. More specifically, each rotor consists of a plurality of annular walls 52, between which is placed a series of rearwardly inclined blades 54. It has been found that this particular type of rotor is exceptionally efficient and the employment of blades 54, which do not have free ends and which incline rearwardly from their point nearest shaft 46 to their connection with walls 52, efficiently utilizes the minutes air current. A drum 56 is created around shaft 46 by one of walls 52 and deflectors 58 and 60 direct the wind against blades 54.
In view of the fact that generator 62 should be driven at a substantially constant speed, and since the wind forces will vary from time to time, it is necessary to supply shutters 64 to maintain a substantially constant wind pressure against said rotor. Basically, shutters 64 should be movable to and from a position Where they close entirely the entrance to rotor 44 through deflector 60. The structure whereby shutters 64 may be operably mounted is herein illustrated to be an upper and lower frame 66 that slidabiy engage the upper and lower edges of shutters 64 through the medium of pins or rollers 68. Each rotor 44 should have two shutters 64 and mecha nism for actuating the shutters simultaneously should be carried by turntable 18. A central vertical shaft '70 and a shaft '72 at each side of the entrance to rotor 44 are rotated to move shutters 64 in the appropriate direction.
Vertical shafts '70 and '72 are driven by motor '74, geared to actuate said shafts as shown in Figs. 3 and 5. Obviously, a speed reducer '76 might be utilized and since it becomes necessary to rotate shafts 70 and '72 in both directions, motor '74 is of the reversable type. Power to drive motor '74 is obtained from generator 62, which is driven by connection '78 as long as rotor 44 is turning about shaft 46. A governor assembly is combined with the mechanism to be driven by rotor 44 simultaneously with the aforementioned generator 62. A detailed showing of this generator and governor connection is shown in Fig. 5 and a more specific illustration of the governor itself is illustrated in Fig. 7. Current to motors '74 is supplied thereto by the closing of the appropriate circuit only when air currents to rotor 44 are such as to effect the desired constant speed of generator 62. That is to say, when the force of wind diminishes to a point where generator 62 will decrease its speed of rotation below a predetermined minimum, governor arm 82 will be moved upwardly by governor weights 84, whereby to move the operating lever 86 of switch 83 to a position where it will carry contact points 91 to engage similar points 93 which causes motor 74 to rotate shafts 88 in the appropriate direction tomove shutters 64 toward the completely opened position. Manifestly, the rotation of shafts '70 and 72 in a direction whereby shutters 64 are opened, will wind cable 90 and unwind cables 92 at the center shaft '70. As shutters 64 are moved to an open position, an increased wind pressure will be set up against rotor 44 and its speed of rotation will be increased to a point where governor 80 will move governor arm 82 downwardly to disconnect switch points 91 and 93. If wind pressure is increased sufiiciently to cause rotor 44 to travel at an excessive speed, governor weights 84 will move arm 82 downwardly to carry contact points 91 against contact points 95, whereby the direction of rotation on the part of motor '74 is reversed from that previously mentioned and shutters 64 are drawn toward the closed position.
To preclude running of motor '74 after shutters 64 have reached the completely open or closed position, there is provided a pair of switches 96 for each shutter 64 or, to fulfill the purpose of the invention it is necessary to equip but one shutter 64 of each set thereof with two switches 96. These switches 96 are stationary and project into the path of travel of a pin 98, carried by the adjacent shutter 64. When the shutter reaches the end of its path of travel in either direction, one of said switches 96 is opened to break the circuit supplying energy to motor '74. The other of said switches 96 is in the closed position and a movement on the part of governor 80 to close that circuit of which said closed switch 96 is a part, will immediately actuate motor '74 to draw shutters 64 back through a path of travel opposite to that through which the same just traveled.
Thus, there is provided mechanism controlled by the rotor-actuated governor 89 which controls the speed of rotor 44 by varying the wind pressure thereagainst. A main switch 100 should be interposed in the shutter-actuating circuit whereby the whole may be made inoperative if such becomes desirable or necessary.
Reference is here made to Fig. 10 for an understanding of the circuit which is in operation as the shutters 64 are being moved toward the completely opened position. As previously set down, contact points 91 and 93 are together. Main switch 100 is closed, generator 62 is supplying current to motor '74 and pin 98 is moving toward yieldable contact point 102 now in engagement with fixed point 104. Energy will pass from generator 62 by way of wire 106 to motor '74; thence from motor '74 by conductor 108 to rigid arm 104; to contact point 102; wire 110; contact point 93; contact point 91; conductor 112; main switch 100 and thence back to generator 62. Assuming that shutters 64 are being closed and contact points 91 are engaging points 95, motor '74 will be traveling in a reverse direction from the aforementioned condition, and the circuit defined as follows:
to wire 114; to branch 116; to contact point 102 of switch 96. Thence to rigid arm 104; to wire 118; to contact point 95; to contact point 91; to conductor 112; main switch 100; and thence to generator 62.
Governor may be of the well known commercial type, wherein is incorporated means for changing the effective operation of the same with respect to causing it to commence actuation of shutters 64 at any predetermined rate of rotation on the part of rotor 44.
As previously set down in the objects, means is provided for automatically facing rotors 44 directly into the path of travel of the air current. The necessity of such an expedient becomes obvious when it is remembered that the direction of 1 wind travel might be diametrically opposite within a very short length of time. One embodiment of this point of the invention is illustrated in the drawings and shown to be a rotatably mounted vertical shaft 120 having a vane 122 thereon and projected an appreciable distance above the entire generating apparatus. The lowermost end of shaft 120 supportsan arm 124, the free end of which is disposed between a pair of electrical switches 126, interposed in a circuit having as a part thereof, generator 62. Swinging arm 124 to one side or the other will close the appropriate switch 126 lying in its path of travel and such closing will immediately set up rotation of motor 128 hung'beneath turntable 18 and drivingly connected with wheel 14 forming a part of the group thereof beneath turntable 18. A speed reducer 130 might be used if required, and since the closing of one switch 126 causes motor 128 to rotate in a direction opposite from that which is caused by the closing of the other of said switches 126, it is obvious that the entire generating apparatus mounted upon turntable 18 will be moved along track 12 as the change in wind direction alters vane 122 sufficiently to swing arm 124 toward switches 126.
The operation of this wind operated turbogenerator has been made clear throughout the foregoing specifications. It has likewise been set down that alterations with respect to size might be made without departing from the broad concepts and especially without digressing from the scope of the appended claims.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
