Abstract

The object of this invention is to provide a large scale but low cost windmill by maximizing wind-contact out of the least cost of materials with least cost of maintenance. This is attained by making the sails (100) as large as possible using light materials such as framed fabrics or aluminum sheets, by arranging the large sails (100) to form a long line of parading sails in one direction transverse to the wind and another long line of the same kind parallel to the first line but moving to the opposite direction with which the first line makes a closed loop, by using a strong light weight cable chain (101) that is tugged by the large sails and which also turns the terminal gears (102) located at the two ends of the loop, by using light weight vehicles to carry the large sails.

Description

UNITED SAIL WINDMILL

Technical Field

My invention relates to new designs of windmills in several types to obtain maximum benefit from the energy offered by the wind in a given limited space at a minimum cost.

In the convertion of the wind energy particularly by means of the windmill, it is very essential that the windmill be in contact with as much wind as possible that passes thru a given space at the minimum cost of materials, labor, maintenance, operation cost, and minimum use of space (land or sea), in order to provide competative energy cost to the user. This maximization of wind contact is done by the use of large wind sails made as large as possible, as in the sail boat, with the use of a specially designed mechanical device that handles the large sails in great quantities, at least cost.

In this invention, particular attention is concentrated on the maximum harnessing of the wind energy that is available in a given space in the maximum effeciency and effectiveness of energy convertion out of whatever strength of wind that arrives at the windmill at the least cost of energy production. It is also the objective of this invention to produce a large scale windmill that is capable of driving a large irrigation pump, or to make a remote area energy independent by making the windmill able to work during violent weather conditions to a certain limit ( when energy is abundant) and able to sxore the energy in the form of compressed air, electricity, and/or hydrogen gas at any location — land or ocean. It is also the objective of this invention to make the ordinary man able to construct his own energy machine and to free the poor nations from highly commercialized high technology machines. It is to ease the pressing problem of having to import energy from other nations when in fact there so much energy at home. Self sufficiency on energy promotes peace around the world. Background Art

The first prior art is the rotary blade windmill which has very limited power output capacity because it cannot be expanded large enough as much as it is wanted so as to increase the wind contact. To increase the wind contact of the old rotary windmill is done only by attatching longer blades but only to a limited extent because the tip of the blades will be moving faster than the wind - that means loss of energy. This means that the old rotary type of windmill cannot be constructed to a very large scale for purposes of having as much wind contact as it might be wanted. The available wind being offered by nature is so much on land as well as on the ocean from sea level to 3 miles up all over the earth -- but the rotary windmill is just too small to tap the opportunity. From this view point, there must be another design of a windmill that can maximize wind contact any where in order to maximize benefits from the available wind, hence, the new invention herein presented.

The second prior art is that presented by H. A. STENNER under U.S. Patent No. 3,504,988 which makes use of a wind sail carried by a trolley which assembly is linked to other several trolleys with sail in a closed circuit traveling along an elongated closed loop double track railway. The system is provided with electro-mechanical control system to keep the sail oriented to the direction of the wind. This system is also provided with a closed loop drive chain which is tugged by each of the trolleys, and which drives the terminal gear that drives directly an electric generator. The mast holding the sail stands alone without guy wires. The sail which is supported vertically along the middle axis by the single mast is built rigid thick and solid designed not to bend any part against the wind force. The Trolleys are supported vertically on its four (4) corners by wheels running inside a channel-shaped beam laid on its side that serves as rail track. The principle envolved is best because it attemps to make the several sails to work in consortium but the following defects prevents the commcercial use of this invention:

1. It drives the electric generator directly without the use of a compressed air storage that would stabilize the electric out put even after the wind had stopped;

2. The mast that holds the sail is not provided with guy wires and/or strut braces. This reduces the size of sail it can hold against the forces of the wind. Wind contact/cost ratio therefor is very low; 3. The sail is built rigid and thick with double wall designed not to bend any part against the wind force. This makes the sail very heavy with too much materials used. Wind-contact/- cost ratio therefor is very low; 4. The trolleys are supported on four (4) corners by wheels for vertical loads only. There are no wheels to take care for horizontal loads which are directly imparted. by the wind -- causing great amounts of friction upon the vertical inner walls of the channel-beam track by the wheels — hence, low effeciency in energy convertion due to energy losses;

5. The drive chain having been placed inside the channel-beem- rail track exerts too much friction upon the vertical inner wall of tne said track at the curved turn around of the rail track system preventing any forward movement of tne trolleys resulting to zero (0) energy out put. Therefor, this machine does not work;

6. The wheels on the left side of the trolleys are de-railed when making the turn around at the curved end of the rail track system which prevents this machine from operating; 7. There is so much electro-mechanical work control system placed on the trolleys to keep the sails oriented to the wind, making the output/cost ratio very low, when in fact automatic orientation of the sail can be done by strings only. 8. This invention makes no mention about maximising wind-contack/cost ratio that is why the design of the sail and its support system is in error.

The third prior art is that presented by Reinhold H. Nilberg, U. S. Patent No. 4,175,910 which makes use of several vanes as sail suspended vertically by two level cable conveyor system. Each of the vanes are supported by two vertical, control bars connected at the top to the upper conveyor cable and connected at the bottom to the lower conveyor cable. Each of the vanes contribute force to move forward the upper and the lower cable which in turn rotate the terminal gears at the same speed (upper and lower gear) to keep the vanes always vertical and prevent distortion of the system. The principle envolved is best because it attempts to cover a wide path of the wind, increasing the wind contact, and attempts to unite the efforts of several sails to work in consortium, but the following defects prevents the commercial use of this invention in large scale, to wit: 1. There are no vertical supports along tne length of the span to prevent sag of the conveyor cable against the weight of vanes and support frames, which makes the windmill limited to a very short span -- not a large scale; 2. There are no horizontal supports for the upper and the lower conveyor cable to work against the horizontal forces of the wind upon the vanes along the length of the span. This allows the conveyor cables to be swaying too far sidewise when pushed by the wind causing over stress or overload on the said cables and on the terminal gears. This limits the use of this invention to a very small scale. Therefore, maximization of wind contact using this invention cannot be achieved at low cost;

3. There are too many vertical bars to support the vanes making the system too heavy forcing the conveyor cables to sag down to the ground. This limits the construction of this windmill to a very short span -- not a large scale;

4. The vanes must be constructed thick and rigid enough to resist twisting as the wind exert force on them because the spring support is acting at one end only at a time. This tends to make the vanes very heavy causing an overload of the system, hence, this invention is limited to a very short span;

5. To provide or to install counter weight 19 is an error because it will desalign the wheels from the catenary slope of the conveyor cable. This will cause friction upon the lips of the gear wheel pulley and wear out the cable conveyor;

6. This windmill drives directly an electric generator without using a compressed air that would be coming from a large storage tank. This will cause a very unstable supply of electricity.

The fourth (4th) prior art is that presented by GODFREY BLACKMAN, British Patent No. 1,588,600, April 1981 which makes use of several wind sails on vertical mast carried by upper and lower bar chain 13,14 which in turn run on wheels following an elongated closed loop upper and lower railway on top of a two-span bridge 1 which in turn rests at its ends on another arc railway track 6,7 on the ground. The theory in this invention is best only on the matter that it attempts to unite the efforts of several sails to work in consortium which is the same principle or objective that the aforementioned 2nd and 3rd prior art are trying to accomplish, but the following defects prevents the commercial use of this invention in large scale or in small scale, to wit: 1. There is too much materials to be used and too much expenses in the construction of the bridge that carry the whole windmill system ;

2. There is too much massive structures to be constructed all over the bridge that will carry the upper level rail track on top of the sails;

3. The fact that the whole system is a two span bridge, the maximum wind contact is limited only to the maximum length of bridge span possible. Summing up all the above listed defects, the energy-output/cost ratio is very very low, hence, it does not achieve the primary objective.

The Fifth (5th) is that presented by LAIRD B. GOGINS, U.S. Patent No. 4,302,684 dated Nov. 24, 1981 which attempts, as in aforesaid prior arts, to unite the efforts of several airfoils, in this case, in the form of vertically and rigidly standing airplane wing -- one wing mounted on and independently carried by separate trolleys that run around an elongated closed loop railway. Each trolley carry its own electric generator and produces electricity thru the turning of the individual wheels and in turn the electric energy is transmitted to a common bussalong the railway track. Each trolley carry its own independent Diesel Engine to continue running the trolley around the railway track during the times when the wind is insufficient so that the wheels of the trolley will continue turning which in turn keep on driving the individual electric generators in order to maintain a continuous power output. The theory in this invention is best only on the matter that it attempts to unite the efforts of several airfoils such as the standing wing to work in consortium which is the same principle or objective that the aforementioned 2nd, 3rd, and 4th prior art are trying to accomplish, but the following defects prevents the commcercial use of this invention in large scale or in small scale, to wit:

1. The standing airplane wing 300 ft high requires a heavy frame contruction to stand rigid against the wind it being supported on two points only, and to stand rigid like a crane boom against the downward compression effects of the guy wires; 2. The rail track requires a heavy concrete construction in order to produce an open trapezoid channel section rail large enough to accomodate the wheels into the internal dimentions of the channel. The horizontal cantelever lips of the rail that serve as bearing to hold the wheels must be constructed strong enough to be able to contain the heavy vertical weight of the trolleys; 3. The ground which serves as footing for the heavy rail track needs to be horizontal, level and well compacted roadway which requirements makes this invention very selective of project site and is limited to a very few available choice lands; 4. The design of the airfoil, being a wing, is very very narrow which in effect, with all the wings arranged along the rail track, will contact or deflect 1/7th only of the total wind available that is traversed by the rail track, hence, this particular prior art has the least wind-contact among all the prior arts;

5. In summary, this prior art is very expensive due to the construction of heavy structural framework for the wing, due to the construction of heavy concrete trapizoid channel rail, due to the construction of a level& well compacted roadway to serve as footing for the heavy rail track, due to the requirement of having 48 wheels for every trolley, due to the requirement of having one diesel engine for every trolley, due to the requirement of having one electric generator for every trolley, and because the wing has a very small wind-contact the resulting output/cost ratio is very small and disappointing.

The Sixth (6th) prior art is that presented by RUTLER under France Patent No. 2523220 dated Sept., 1983 which makes use of and unites the efforts of several sails as in the aforementioned prior arts. The sails are double wall, rigid like that of the airplane wing, supported by a rotating vertical mast(without guy wires) which is in turn erected on top of a continuous circular horizontal frame that turn around on rollers on top of a circular horizontal rail track. The pick-up wheels fixed on the ground driving the electric generator, is actuated by a continuous circular friction plate attached to the main circular frame that act as vehicle for the sails. The theory in this invention is best only on the matter that it attempts to unite the efforts of several sails to work in consortium which is the same principle or objective that, the aforementioned 2nd, 3rd, 4th, & 5th prior arts are trying to accomplish, but the following defects prevent the commercial-use of this invention in in any scale, to wit:

1. One-half (1/2) of the total number of sails cover each other from the wind which reduces down to 30% the wind force acting upon said sails while traveling along the direction of the wind, hence, less wind-contact or less energy converted per sail;

2. One-fourth (1/4) of the total number of sails must stay nutral while traveling against the wind, hence, less energy converted per sail;

3. This design cannot be erected on rough land terrain where the wind is mostly stronger, and further, there is wider land occupation per sail, hence, it is very expensive;

4. The sail is designed to act stiff against the wind like an airplane wing -- so it requires a heavy structural frame it being a double wall with the assistance of guy ropes, hence, it is an expensive construction;

5. The mast,which supports the heavy sail, stands alone without the assistance of a guy wire, must be a heavy structure to withstand the tremendous bending stress at the base, otherwise, the size of the sail must be a small one; 6. The system being a circular horizontal structure occupies a very wide level land, hence, the maximum size of this type of windmill is limited only to the available diameter of the level land project site; 7. The main circular frame (part 4) which revolve around on top of the circular rail track requires a very massive structural construction in order to be able to hold the heavy mast uprignt against the wind, and since this main frame is continuous around the circualr rail track it is a very expensive structure. Summing up all the aforementioned defects of this design, the resulting energy-output/cost ratio is very small.

The Seventh ( 7th ) prior art is that presented by Bruno May under Deutschland Patent No. 2836922 dated March 13, 1980 consisting of large quantities of composit sail mounted on a continuous floating circular raft on a lake and the other one presented by British Patent No. 25,234 dated Dec. 1394 consisting of sail boats floating and traveling thru a concrete circular channel - the boat being a continuous ring structure with the same diameter as the concrete water channel and acting as pulley that drives the power chain. These two prior arts, being a revolving circular structure, has the same defects and deficiencies as tne aforementioned Sixth (6th) prior art by Rutler under France Patent No. 2523220 in which I have listed 7 impediments in page 7 hereof preventing commercial use of these circualar designs.

Summary of the subject invention:

The "UNITED SAIL WINDMILL" is designed to solve all the aforementioned problems or impediments encountered preventing the large scale commercial use of the aforementioned prior arts, and further intends to accomplish the functions of the crises creating "OIL" and/ or the dangerous expensive nuclear energy in the poor nations. This newly invented windmill is designed to have as much wind contact as may be desired and intends to work even during the violent weather when the energy is abundant which is to be stored in the form of compressed air in large underground tunnels. The compressed air will, in turn, drive the electric generator to an extended time even after the windmills (in consortium) had stopped working as the wind stops. it is also designed to be easily constructed by the ordinary man out of low cost materials that are already available.

There are ELSVEN (11) inventions being applied for Patent Rights under this presentation, namely: (1.) "UNITED SAIL WINDMILL TYPE-1"; (2.) "SUSPENSION HOLDER FOR A RUNNING CHAIN HAVING VERTICAL BAR LOADS"; (3.) "LIGHT WEIGHT CABLE CHAIN"; (4.) "UNITED SAIL WINDMILL TYPE-2"; (5.) "UNITED SAIL WINDMILL TYPE-3"; (6.) "ROLLER PULLEY WITH GEAR-LOCK RUNNING ON/OFF A SUSPENDED CABLE RAIL"; (7.) "CABLE RAIL SWITCH ON/OFF CONNECTOR"; (8.) "CABLE RAIL INTERMEDIARY SUSPENSION SUPPORT"; (9.) "UNITED SAIL W IND MILL TYPE-4"; (10.) "UNITED SAIL WINDMILL TYPE-5"; (11.) "UNITED SAIL WINDMILL TYPE-6".

How these presented inventions solve the aforementioned problems of the referred prior arts:

1. The "UNITED SAIL WINDMILL TYPE-1, TYPE-2, TYPE-3,

TYPE-4, TYPE-5, and TYPE-6 all solve the maximization of wind contact by making the wind sails as large as desired and attaching as many sails as desired in the maner as shown in the drawings thereby operating the windmills in a very large commercial scale is very easily attainable. By using these large windmills in the production of compressed air, it will be very easy for these windmills to work in a consortium by interconnecting their compressed air pipe lines to a common depository air tank ( in the form of underground tunnel or a series of tunnels thru a mountain ) in order to be able to drive a large electric power plant;

2. The herein presented inventions No. 2, No. 3, No. 6, No. 7, and No. 8 are the most important components that brought about the possibilities of expanding the different types of the "United Sail Windmill" into very large windmills as may be desired because they make the windmill work and stand rigid against the strong winds thereby allowing the construction of a very long span transverse to the general direction of the wind, hence, a very powerful windmill;

3. By constructing a large windmill floating on the ocean as illustrated by invention No. 10 - united Sail Windmill Type-5 -- in the form of sail boats in a long single line formation tugging a long common cable/chain, a large portion of the ocean which is free can be converted into a wind farm. In case of violent weather these boats will be submerged underwater and then refloated after the hurricane is gone. Thru this method, maximum benefit from the wind over the unlimited ocean is made possible.

4. The low cost of construction with a resulting high power production attracts the investors to go into a large commercial scale of operation. The high wind-contact/cost ratio provided by these new inventions is the only deciding factor for a large scale use of these new designs. Brief Description of the Drawings:

FIG. 1 is a schematic perspective view of tne invention No. 1 — "UNITED SAIL WINDMILL TYPE-1" showing the arrangement of at least Twenty (20) large wind sails, the power chain, the terminal gears, and the support structures. It is a long line of parading wind sails, transverse to the wind in one direction, that turn around a terminal gear at one end of the loop then make another long line of parading sails in the opposit direction (may be one or more miles long), then turn again at the other terminal gear at the opposit end to make a closed loop. Each wind sail is suspended in mid-air by a horizontal power chain at the top and by another horizontal power chain at the bottom that move horizontally at the same speed by driving the upper and the lower terminal gear which are synchronized and locked to each other by a long vertical axil that carries the power take-off gear and which is held in place by a strong structural bearing. Since there are inteimidiary supports for the power chain to hold it in place, as shown in the drawings, the power chain will not sway side ward nor be overloaded, and this permits the construction of a very long and very large windmill of this kind even one or three miles or more miles accross a windy valley carrying one thousand or more sails in the system.

FIG. 2 is a schematic perspective view of the terminal gear of the "UNITED SAIL WINDMILL TYPE-1" in an enlarged detail drawing showing in detail the low cost of construction and synchronization of the two large diameter wheel gears, the construction of the sails and how the sails are carried by the power chains. The long radius of the terminal wheel gears allows the construction of a wider sail resulting to a large wind contact as shown.

FIG. 3 is a schematic perspective view of the mid-section of the "UNITED SAIL WINDMlLL TYPE-1" showing in detail the construction of the invention No. 2 -- "SUSPENSION HOLDER FOR A RUNNING CHAIN HAVING VERTICAL BAR LOADS" -- one type holding in place the upper power chain and another type holding in place the lower power chain. The whole weight of the sail and the chain rests on the lower suspension holder so as not to introduce wear-and-tear upon the upper chain. This figure also shows in detail the construction of invention No. 3 -- " LIGHT WEIGHT CABLE CHAIN". The long tooth gear lock of the suspension holder is very necessary to prevent the power chain from getting out of the rollers during violent weather yet it allows the vertical mast of the sail to pass thru.

FIG. 4 is a schematic perspective view of the terminal gear and the power station of the "UNITED SAIL WINDMILL TYPE-2" showing in detail the construction of the invention No. 4 in the form of a double story windmill similar to the said Type-1 but this Type-2 is suspended high in mid-air by means of the power chain which is in turn suspended by tall structures ( wood poles or steel towers ) thru the terminal gears and by intermidiate supports such as the herein invention No. 2 -- the "Suspension holder for a running chain having vertical loads". This figure also shows how the energy from the upper level windmill and the energy from the lower level windmill is transmitted to a vertical drive shaft or bar. It also demonstrate how the vertical weight of the power chain is carried or supported by the terminal gears. The terminal gears may be tilted to the slope of the power chain to prevent friction wear on the chain.

FIG. 5 is a schematic perspective view of invention No. 5 -- the "UNITED SAIL WINDMILL TYPE-3" a long line of several sails suspended high in mid-air similar to the said Type-2 windmill but this Type-3 is supported all along its horizontal length by means of a fixed high tension Cable Sail along the upper power chain and by another Cable Rail along the lower power chain. Also shown is a roller pulley with a long toothed Gear Lock (invention No. 6) that carry the sail on the Cable Rail. The long toothed Gear Lock prevents the sail from being derailed during violent weather. Also shown are new designs of cable rail switch on/off which allows the gear lock to pass thru, and the mid-air intermediate support for the cable rail that allows the gear lock to pass thru also. These are invention No. 7 and invention No. 8 respectively.

FIG. 6 is a schematic perspective view of invention No. 9 -- the "UNITED SAIL WINDMILL TYPE-4 which is a long line of several sails similar to the herein aforementioned windmill Type-1, but in this Type-4 all the sails are running on an elongated (a mile or more) closed loop Rail Road Track and there is only one Power Chain being tugged along the rail track by the wind sails on trolley. Also shown are the three synchronized Power Terminal Gears at each end loop of of the rail track which are directly anchored to the ground.

FIG. 7 is a schematic perspective view of the invention No. 10 "UNITED SAIL WINDMILL TYPE-5" which is similar to the herein windmill Type-4, but in this Type-5 each wind sail is carried by a Sail Boat and the whole windmill is constructed floating on water surface (lake, sea or ocean) forming a long parade of sail Boats (a mile or more) in one direction, turn around on the terminal gears at the end loop, then make another long parade of Sail Boats in the opposit direction and turn around at the opposit terminal to make a closed loop also shown is a barge anchored to the sea bed which carry the terminal gears and serves as power terminal station. For safety purposes this whole boat windmill system will be deflated to submerge under water during violent weather and then will be refloated by compressed air after the hurricane is gone.

FIG. 8 is a schematic perspective view of the invention No. 11 "UNITED SAIL WINDMILL TYPE-6" which is similar to the aforementioned windmill Type-1 in mechanism, but in this Type-6 the axil of the synchronized terminal gear wheels are horizontal and the wind sails are carried up and down by the pair of closed loop Power Chain. The wind sails spread up agianst the wind when they turn up above the Power Chain and then they close without resistance to the wind when they turn down below the Power Chain. This is an inclined windmill. The front terminal gear is in lower elevation or anchored close to the ground while the rear terminal gear is at higher elevation or mounted on top of a high structure so that each of the wind sails is fully blown up by the wind. This type of windmill is adoptable on sloping grounds (beaches and hill sides) that face the wind. It works on direct wind, oblique, and reverse winds. On the reverse wind the sails will spread up against the wind when they are under the chain. DESCRIPTION OF THE PREFERRED EMBODIMENTS:

FIG. 1 and FIG. 2 illustrate and embodiment of the invention No.1 named as "UNITED SAIL WINDMILLL TYPE-1" which is moved and/or energized by wind that blows from any direction. As the wind blows the sail 100 resist or deflects the wind thereby exerting effort thru the control stringll and thru the sail mast 110 upon the upper and the lower power chain 101 in a counter-clock-wise direction. As the power chain moves, it turns the terminal power gear 102 (upper & lower) in a counter-clockwise direction too. As the Power Gear 102 turns the vertical axil 105 which holds and synchronizes the movements of the upper and lower Power Gear, will also turn the Power Take-Off Gear 114. The vertical axil 105 is held in place at the top by the structural support (with bearings) 103, and held in place at the bottom by structural footing (with bearings) 106 anchored to the ground. The structural support 103 is held in place by tall standing structures 104 (wood poles, steel poles, or steel towers) which is in turn held standing rigid by guys (rope, chain,wire, or tension bars) 108. To relax the Power Chain from too much vertical loads, it is carried by intermidiary rollers support 107 at several points along the span at the bottom chain sitted on footing 106. To prevent the upper chain from swaying left or right due to the horizontal transverse force of the wind, the lateral support 109 is designed to hold tne upper chain 101 in place. The lateral support 109 is suspended, at several point along the span of the chain, in mid-air by strong wire rope 108 thru tall structures 104 which are in turn anchored to the ground by anchore block 112. The Power Take-Off Gear 114 can in turn drive an air compressor which deposit compressed air to a large cental reservoir that supplies continuous energy.

FIG. 3 illustrates an embodiment of the invention No. 2 named "SUSPENSION HOLDER FOR A RUNNING CHAIN HAVING VERTICAL BAR LOADS" the function of which is to hold the power chain 101 in place while said chain is running with the ability to prevent vertical and lateral movements of said chain at the same time allowing the vertical mast of the sails to pass thru said holder. As the Power Chain 101 carrying the sail by the vertical mast 110 moves thru said holder, the roller 119 together with the long toothed gear lock will be rotating. Every tooth of the lock gear 113, having been constructed like an inclined plane, will be sliding under the said chain producing a lifting effect on the chain 101 at the same time the vertical bar 110 (sail mast) passes freely between the teeth of the lock gear 118 (long tooth gear). Another best mood of carrying out this Suspension Holder is to make the lifting lock gear 118 stay tilted 30 degrees in order to give the Power Chain/a good saddle ride on the long toothed gear 118 to prevent friction wear between the long toothed gear 118 upon the power chian 101. In this mood, the mast 110 being vertical, the axis of rollers 119 & 120 are also tilted 30 degrees to the right, roller 120 will be an upright 30 degree cone while roller 119 will be an inverted 30 degree cone, and frame 121 will be tilted 30 degrees up to the left. The roller 120 keeps on pressing the power chain 101 against the roller 119 so that the chain 101 will be forced to ride at the base of the long toothed lock gear 118. Another chain holder is the one holding the lower chain 101 at the bottom of the sail 100. This holder is an ordinary but deep pulley that exert uplift support and lateral support to the lower power chain. To prevent the chain from getting out of the pulley during violent weather,the lock gear 118 is intalled over the chain 101. Said lock gear 118 is freely rotating horizontally on top of the lips of the roller pulley 107 when the mast passes-by in which case the chain 101 is enclosed but the vertical mast 110 is allowed to pass thru over the roller pulley 107.

FIG. 3 also illustrate the imbodiment of the invention No. 3-- "LIGHT WEIGHT CABLE CHAIN" which is in the form of two parallel cable ropes 101 (made of steel or nylon strands) joined together to form a chain by means of short bars 116 (made of nylon tubes or metal tubes) attached perpendicular to the ropes 101 -- one rope clamped to one end of said short bar 116 and the other rope clamped to the other end of said bar 116. The length of said bar depends upon the thickness of the terminal gear 102. The distancing of said bar 116 depends upon the distancing of the teeth of the terminal gear 102. The bar 116 is clamped very tight to the rope 101 be means of the bolt 138 which passed thru the center of the rope 101. This type of chain is very much stronger in tension stress than any other type of chain of its equal weight. The ideal chain for a windmill specially the type herein must be made as light as possible.

FIG. 4 illustrates an embodiment of the invention No. 4 named "UNITED SAIL WINIDMILL TYPE-2" which works in the same principle as the aforementioned windmill Type-1 Fig. 1 except that it is made into a double story windmill and it is elevated high in mid-air in order to get the benefits from the higher speed winds. In this Type-2 windmill, the terminal gears 102 are smaller than those of the Type-1 but there are two gears for each chain at each terminal. Said terminal gears 102 are made to be far appart as shown in the drawings to make the return trip of the sails stay far away from the forward line in order that the return sails will get more benefits from the wind. This Type-2 windmill most importantly emphasizes the possibility of maximizing wind contact at the least cost of construc- tion using a limited land space, using very tall support structures 128 & 129 to build a multistory or multi-level windmill. To build, this type-2 windmill, the Type-1 windmill will be elevated high to the mid-air by means of the steel tower 129, the tower arms 128, the terminal gear bearing holder 122, the terminal gear synchronizing chain 125, the energy transmitter chain 126 with the corresponding transmitter gears 123 & 124, and the central drive shaft 127 that receives the power from the different levels of windmill and drives the power take-off gear 114. With the use of Suspension Holder 107 & 121 as illustrated in FIG. 3 the span of this multi-level windmill can be two or more miles long or as long as desired, and the sails can be made as large as desired.

FIG. 5 illustrates an embodiment of the invention No. 5 named "UNITED SAIL WINDMILL TYPE-3" which is the same high elevation multilevel windmill as the aforementioned Type-2 windmill, except that the whole weight of the sail and the power chain is carried throughout the span by a suspension high tension Cable Rail 132 which is keepped in place elevated high in mid-air by means of tall posts or steel towers. With the use of intermidiate suspension support 137 at several points along the span to support the Cable Rail, it will be possible to construct a very long span (two or more miles long or as long as may be desired) of windmill of this type across mountain passes or over the valley. The presence of the Cable Rail 132 relaxes or relieves the Power Chain 101 from the vertical weight of the sails 100 -- a condition giving the chane to use a smaller and lighter Power chain 101 with a smaller and lighter Terminal Gears as illustrated in this figure.

This FIG. 5 also illustrates an embodiment of the invention No. 6 named "ROLLER PULLEY WITH LOCK RUNNING ON/OFF A SUSPENDED CABLE RAIL" which is an ordinary roller pulley 133 with deep groove adotable to the size of the cable rail and its joints, attached to the top end of the sail mast 110 in line with the uppoer power chain 101 and the other roller pulley 133 is attached to the lower end of the sail mast 110 in line with the lower power chain 101 -- each pulley rolling on the upper and the lower Cable Rail 132 respectively. To prevent the ruller pulley 133 from being derailed during violent weather, the long toothed Lock Gear 134 is incorporated by attaching it to the sail mast using said mast as its axil, fixed just touching the lips of the roller pulley 133 enclosing the Cable Rail 132 in between the roller pulley 133 and the Lock Gear 134. This FIG. 5 also illustrates an embodiment of the invention No. 7 named "CABLE RAIL SWITCH ON/OF CONNECTOR" which brings out the opportunity to cut off the cable rail 132 at the terminal to allow the roller pulley 133 get off the rail 132 and to permit the roller pulley 133 to make a turn around the Terminal Gear 102. Said connector 135 is a strong steel plate able to hold the Cable Rail in place with special windows 136 in correct size and spacing in straight line just below the Cable Rail 132 to allow the free passage of the Lock Gear 134. Said connector 135 also allows the free entry of the roller pulley 133 and the Lock Gear 134 into the cable rail 132 after the turn around. There is no need to install a cable rail along the terminal loop because it is a very short span .and the terminal gears /canbe tilted to align with the slope of the power chain 101.

This FIG. 5 further illustrates an embodiment of the invention No. 8 named as "CABLE RAIL INTERMIDIARY SUSPENSION SUPPORT" which brings about the opportunity to expand the windmill on cable rail into a very long line ( a mile or more ) by supporting the cable rail at several points along its span length. Said suspension support 137 is a strong plate that holds the cable rail 132 in place and support it laterally and vertically. Said plate 137 is provided with special windows 136 in correct sizes and spacing in straight line just below the cable rail 132 to allow the free passage of the Lock Gear 134. Said intermidiate support plate 137 is suspended in mid-air by guy ropes 108 tied to tail structures 104 or 129.

FIG. 6 illustrates an embodiment of the invention No. 9 named "UNITED SAIL WINDMlLL TYPE-4" which has the same principle as the herein aforementioned windmill Type-1 (several large sails tugging a common power chain) except for the following new special features and in the best mood it is carried out, to wit:

1. All the wind sails 100 are each carried by a trolley car that rolls on a very long (two or more miles) elongated closed loop rail road track 140 transvers to the wind foming a long parade of large sails in one direction and another long line parade of large sails in the opposit direction;

2. Only one closed loop power chain 101 with the same length as the inner rail track is used to gather all the energies from the sails 100;

3. Each of the Sails is carried by a separate triangular trolley car 146 with its wheels 141 & 142 lock or hooked to the rails

140 to prevent overturning;

4. There are three terminal gears 102 installed in triangular formation at each end of the loop to receive the energy from the power chain 101; 5. The rail (in the form of flat bar metal or timber bar) 140 is elevated from the ground by the support structures 143 & 144 in order to give chance for the lower wheels 142 to do a hook grip at the bottom of the rail 140. As the wind blows, the sail 100 pushes upon the mast 110 at the same time pulls the succeeding mast 110 thru the control rope 111. The mast 110 in turn pushes or pulls the structural braces 145 transmitting the force to the structures of the car 146 making the wheels 141 start rolling on the rail track 140 while the wheel 142 prevents the overturning of the trolley car 146 by pressing against the bottorn of the rail track 140. As the car 146 moves forward, it pulls the rope 148 which in turn tugs the power chain 101. The power chain 101 turns the terminal gears 102 which drives the synchronizing chain 125 which joints the forces of the three terminal gears 102 in order to distribute the great force of the chain to more tansvers bars 116 of the chain 101 that are in contact with the terminal gears 102. The center terminal gear drives the power take-off gear 114. Rope 147 holds high the sails thru bearing 131 that allows the sail to turn around the mast 110.

FIG. 7 illustrates an embodiment of the invention No. 10 named "UNITED SAIL WINDMILL TYPE-5" which has the same principle and of similar construction as the aforementioned windmill Type-4 except for the following special features, to wit:

1. The whole windmill system is floating on water (sea or lake, or on the ocean);

2. Each of the wind sails 100 is carried by a separate boat 154 on which the mast 110 is erected and forms a very long line of parading sails out on the ocean;

3. The terminal gears 102, in triangular formation, are installed on top of a floating barg 153 which is held in place by anchor blocks 112 thru guy rope 108.

As the wind blows the sail 100 exerts force on the boat 154 to a direction opposit to where the wind is deflected. As the sail 100 tends to overturn the boat 154, the counter weight 151 moves to the opposit side of the boat thru a small rail by action of a rope being pulled by the sail 100. As the boat 154 moves forward, it tugs the Power Chain 101 by the tug rope 148. The boats 154 turn around at the terminal by the action of the Power Chain 101 upon the front tug rope 148 which pulls the boat 154 to where the power chain 101 is going. The fender plate 152 prevents the boats 154 from getting over into the other side of the power chain 101, at the same time prevents the boat 154 from being blown sideward by the wind resulting to an unnecessary stress to the power chain 101. Strat braces 145 keeps the mast 110 stay erect rigidly. Bridge 154 carry the whole weight of the mast 110 and keep the float 150 stay together in the form of an "H" frame. Bearing 131 carry the whole weight of the sail 100 thru string 147 and allows the sail 100 to revolve around themast 110. There are two barg 153 in the system -- one barg at each end of the loop that serves as power terminal station, carrying the terminal gears 102, 114, 125, and other station accessories. This barg 153 is anchored to the ocean floor by means of heavy block 112 thru rope 108. Control rope 111 holds the sail to face against the wind, which has guaged springs that will relax the sail 100 when the force of t he wind becomes excessively strong, but tries to adjust the sail 100 to be fully facing the wind when the speed is very low. In the event of a violent weather, the boat loaters 150 and the barg 153 will be deflated to submerge the whole system under water to scape distinction by strong winds and haeavy water waves. When the hurricane is gone, the whole system will be refloated again by means of compressed air. This type of windmill is expandable as much as the open ocean by installing intermidiary horizontal supports at several points along the span of the power chain 101 in the form of a deep groove roller pulley with lock gear similar to parts 107 & 118 shown in Fig. 3 which will be mounted on floating floating rafts anchored to the ocean floor.

Fig. 8 illustrates an embodiment of the invention No.11 named "UNITED SAIL WINDMILL TYPE-6" which has similar principle and construction as the aforementioned windmill Type-1 except for the following special and additional features, to wit:

1. The axil 105 of the terminal gears 102 are horizontal;

2. The sails 100 & 200 are blown up and spread open by the wind upon turning up and ride on top of the pair of Power Chain 101.

3. The sail 100 carries with it additional sails 200 that flip out open on each side of sail 100 and another 3rd sail 200 that flip out open down ward at the bottom of sail 100 between the power chain 101 to maximize blockade against the wind for more energy benefits;

4. The whole system is an inclined line where the front terminal gear 102 is at a low elevation while the rear terminal gear

102 is at a much higher elevation using a much taller post 103 or at the top of the hill so that every sail faces the wind fully and directly. for maximum benefits. As the wind blows all the sails 100 & 200 that are on top of the power chain will spread up wide open and move the chain 101 to the rear and turn the terminal gears 102 which in turn drives the axil 105 which turns the power take-off 114. As the sails turn down at the rear terminal and go under the power chain, they flip closed and relax to the wind forces. Guy bar 108 makes the structures stand up rigidly. Bar 110 is the sail mast in horizontal position which holds all the four sails at one point. Part III is the guy rope that makes the sail stand rigid against the wind, which has a control spring that is able to relax the sails when the wind is excessive. The ground foundation 113 hold the post 103 in place. Several windmills of this type-6 may be constructed adjacent and side-by-side to each other using the structural posts 103 as common post for every adjacent windmill, while the axil 105 can be made continuously long axil common to all succeeding side-by-side windmills. In the construction of several adjacent windmills of this type, the axil 105 may be preferably cut and discontinuous to provide clear space for the bottom sail 200 so that same can be constructed to be a wider and longer sail and to save axil materials. The only axil needed will be the axil holding the right terminal gear 102 of the first windmill at the same holding the left terminal gear 102 of the next adjacent windmill on the right, and so on. In this preferred mood, maximunm wind contact at least cost of energy convertion can be attained.

Steel springs of appropriate strength are installed in the said folding sail assemblies to assist it to fold closed after turning down and move against the wind;

Steel springs of appropriate strength are also installed in the said control ropes of the sails in order to automatically relax said sails when the wind becomes excessively strong but the windmill will still be working to take advantage of the abundance of energy;

A power take-off gear operatively attached to the axil of the lower front terminal gear, to drive the compressor and/or other machineries.

12. A plurality of said large windmills working in consortium to supply compressed air to a central reservoir (may be a series of underground tunnels) to run a large power plant, or to run a large irrigation pump, factory machineries, and other pneumatic machines.
