FIELD OF THE INVENTION
 The invention relates to an apparatus for diverting water in more than one direction continuously through return flow jets or nozzles at the wall of a swimming pool and optionally for the aeration of the return water by forming a fountain with the apparatus.
BACKGROUND OF THE INVENTION
 Most in-ground swimming pools have two or more return lines either on the wall of the pool (generally about 6 inches below the tile line) or along the floor (as with in-floor cleaning systems), or with the latter, a wall return port may also be included such as near the steps.
 For conventional wall return ports, the return is a fixed unit, which is only a cover or collar insert for the PVC pipe entering into the pool, with a smaller aperture or orifice to inject water into the pool in one fixed direction or a manually adjustable fixed direction.
SUMMARY OF THE INVENTION
 The present invention is a rotating device that can be attached to the return of a swimming pool. While the conventional return is a fixed unit as mentioned above, the present invention has means for diverting the return water through the return port of the pool in a continuous rotating multi-directional pattern. The apparatus has a housing for a water flow driven gear system, which causes the rotor head to turn freely. Ball bearing washer assemblies may also be incorporated to minimize friction, or other means to minimize surface drag or friction between two rotating adjacent parts may be incorporated, such as small spaced-apart ridges forming relatively thin ledges that separate two adjacent rotating surfaces. In the latter case, the ridges are preferably relatively fine or thin in thickness, thereby allowing only the thin edge to contact the adjacent rotating surface. Of course, the water itself will lubricate and cool friction surfaces.
 The water enters through the gear sleeve assembly causing the turbine blade assembly to turn, which then causes the oscillation of the gear assembly itself, and which then contributes to the revolution of the rotor head to obtain a continuous smooth rotation. The outlet may be radially directed from the rotating head assembly at the distal end of the apparatus or it may be through a flow tube assembly extending radially from the outlet on the rotating head assembly. The outlet at the end of the flow tube assembly may be directed in any desired direction, such as through an aperture that sprays the water over a desired angular pattern such as a 60 degree pattern at a desired angular direction relative to the pool water, for example, at an approximate 45 degree direction toward the pool water. Further, the opening at the outlet may be designed to produce desired aesthetic effects or patterns in the water spray, for example, by using a plurality of small apertures.
 This assembly also has an optional fountain design using the flow tube assembly extending radially from a distal end of the apparatus or using the outlet radially directed from the rotating head assembly at the distal end of the apparatus. The flow tube assembly typically has a spray head nozzle at its distal end to create aesthetic features, such as the pattern of spray mentioned above. In the latter case, the rotation can be stopped with locking means known in the art, to allow for the fountain like feature. A set screw or other mechanism can accomplish this locking feature. Even when the flow tube assembly is not being used, the outlet of the apparatus can be adapted to discharge the water in a fixed single direction using similar locking means.
 The performance of this assembly will enable an existing swimming pool to run much more efficiently encompassing a variety of positive attributes. The area of the circulation of water is greatly increased by diverting the water in more that one direction. By allowing the water to move in many directions on a continuous basis, the chemicals needed to maintain the clarity and purity of the water are disbursed more fluently and effectively, greatly enhancing the quality of the water. The present invention allows the chemicals to be injected down deep into the water with great motion and on a rotating basis throughout the pool. This rotation motion carries a wider and broader purification and distribution area.
 Heating the pool becomes more cost efficient because of the returning water entering the pool in deeper areas causing less heat loss on the surface of the water. There is also a faster distribution of heat throughout the entire pool. The aeration of the water created by the use of the optional fountain feature will cool down the water if it gets too warm.
 Cleaning of the swimming pool water becomes virtually effortless with the thrusting water shooting down the walls of the pool. With the pressure of the streaming water, the dirt is dislodged from the pool walls and suspended into the water for the main drain or skimmer to evacuate into the filter. The flowing water actually breaks the surface of the water to accentuate the skimming action of the pool.
 The in-floor cleaning system works by moving water only on the bottom of the pool, where the rotating wall assembly focuses on circulating water along the walls of the pool down to the radius and floor of the pool therefore enhancing the effectiveness of pool cleaning.
 In addition, the calming sounds of the water cascading from the optional fountain gives a swimming pool a tranquil environment for enhanced relaxation. This optional feature gives any pool owner the option of an aesthetically pleasing fountain at any time even after the pool is totally installed. The pool wall mounted present invention also makes it extremely effortless to create an attractive environment of a waterfall at any time, and is easily returned to an effective cleaning and circulation device in just moments. Anyone with little or no knowledge of a swimming pool can install the present invention, including its optional fountain with the greatest of ease.

DETAILED DESCRIPTION OF THE INVENTION
 As shown in FIGS. 1 a and 1 b , the invention is a pool return flow nozzle assembly and is generally depicted as 10 . As shown in FIGS. 2-4, the invention includes means 12 for diverting a return water from a pool water circulation system 34 back into a pool 36 in a continuous rotating multi-directional pattern, as shown by the rotating arrow symbol in FIG. 1 a.
 The means 12 for diverting the return water causes a continuous rotation of a rotatable head assembly 14 at a distal end of the pool return flow nozzle assembly 10 . The rotatable head assembly 14 including a rotor head 14 a having an outlet port 14 b through which the return water is directed into the pool 36 in the continuous rotating multi-directional pattern. The outlet port 14 b shown in the drawings is circular in shape; however, it may be oval or instead be an array of apertures to distribute the return water in any desired pattern.
 The invention includes means 16 for securing the pool return flow nozzle assembly 10 into a return outlet 32 on a wall 30 of the pool 36 . Most wall port or jets have a threaded collar or fitting, similar to fitting 38 , inserted in the wall 30 . The present invention housing 18 d would simply have a mating connection to secure the invention 10 in the wall port or outlet 32 . Such threaded connections for pool devices are known in the art. For example, hoses for pool cleaners that connect to the wall port 32 generally have a very coarse threaded connection and rubber o-ring seal that allows for a simple engagement of insertion pass the first thread and a twist of the of the hose fitting for securement.
 Means 12 for diverting the return water includes a water flow driven gear system 18 in mechanical communication with the rotatable head assembly 14 . The water flow driven gear assembly 18 is typically an assembly of gears 18 a of the same or different styles mounted on shafts 18 b and aligned within the housing 18 d with guide or gear shaft alignment end plates 18 c . There are many ways known in the art to assemble gears to perform the desired features and the illustrations are merely exemplary in nature. The end plates 18 c may also be provided for each of assembly and manufacture such that the one closest the rotatable head assembly 14 is molded integrally inside housing 18 d . The gear arrangement depicted in the drawings are only intended to be exemplary in nature. For example, a portion of the mating gears could be incorporated integrally to the inside surface of sleeve 18 d . Further, in another typical arrangement, the sleeve 18 d could be eliminated and means 16 for securement to the wall outlet 32 can be attached directly to the wall fitting with the gear assembly connected directly to the rotor head assembly 14 .
 The means 12 for diverting the return water includes a turbine blade assembly 20 in mechanical communication with the water flow driven gear system 18 . The turbine blade assembly 20 shown in the drawings is also exemplary in nature. The style and structure can vary, as well as the angle of the blades 20 a.
 The inlet into the means 12 for diverting the return water further includes means 22 for channeling the return water in a desired pattern toward the turbine blades 20 a of a turbine blade assembly 20 . The channeling means 22 is preferably a plurality of apertures 22 a in a predetermined array. Although the apertures may be axially aligned with the housing 18 d , in order to enhance the capture of the water flow onto the blades 20 a of the turbine blade assembly 20 , the apertures 22 a may be oriented through the face of the inlet at an angle so as to direct the water toward the surface of the blades 20 a.
 When it is desired to stop the rotation of the rotor head 14 a , locking means 24 for holding the rotor head 14 a in a fixed direction may be optionally provided. This can be done in a number of ways known in the art. For example, the drawings show a screw that may be turned against a flat surface (not shown) of the rotor head 14 a . Typically, the screw would have a flat end (not shown) that sets against the flat surface to stop rotation. Alternatively, another example is the use of pins or spring-loaded pins for stopping the rotation.
 Means 16 for securing the pool return flow nozzle assembly 10 into a return outlet 32 on a wall 30 of the pool 36 may be secured to the inventive nozzle sleeve 18 d by threads (not shown) or by screws in a keyway (not shown) or by other means known in the art, including permanent adhesive bonding or PVC welding.
 When fountain like features are desirable, the assembly 10 can incorporate a flow tube assembly 26 , as shown in FIG. 1 b and FIGS. 3-5. The flow tube assembly 26 would be securable to the outlet port 14 b of the rotor head 14 a . The flow tube assembly 26 has its own outlet port 26 a at its distal end, which is in fluid communication with the outlet port 14 b on the rotor head 14 a . The outlet portion of the flow tube assembly is preferably directionally adjustable up and down as well as rotationally as representationally depicted by the arrows in FIG. 1 b.
 The flow tube assembly 26 extends radially from the rotor head 14 a a predetermined distance from the rotor head 14 a located at the distal end of the return flow nozzle assembly 10 . The flow tube assembly outlet port 26 a includes means 28 for directing the water in a desired pattern back into the pool. The means 28 for directing the water in the desired pattern back into the pool includes one or more apertures 28 a designed to spray the water back into the pool in a spray pattern, the location, size and number of apertures 28 a being selected to obtain a desired aesthetic flow of water through the flow tube assembly outlet port 26 a .
 To summarize generally regarding how the invention works mechanically, a turbine blade assembly has numerous blades placed at an appropriate angle to turn at the best desirable rate. By the proper directional flow created by the assembly of gear sleeve, the turbine blades will respond and activate the gear assembly.
 A turbine blade extension/assembly holds the blades in an appropriate fashion enabling the blades to rotate at a desirable speed. A top plate typically holds the gear assembly together by arms and pins at the appropriate angle for housing.
 The gear assembly is properly set, in such a way that by the affect of the turbine blade rotation, which generates motion through the gear chamber at a gear rate as needed, to propel or rotate the rotor head.
 The rotor head threaded end piece may be a screw in a collar that holds the entire rotating head in a fixed position. The entire rotary wall fitting is held into place by the male threads screwed into an existing fixed position female threaded adapter. This existing fixed position female threaded adapter receives the unit in that the threads screw into the female adapter, which now maintains the threaded rotor head in a fixed position.
 The rotor head sits on top of the threaded rotor head end piece. This rotor head rotates by the operation of the gears at an appropriate rate. The rotating head is internally channeled to allow water to flow freely through the nozzle or outlet. The rotating head nozzle has threads for certain optional attachments. The rotor head moves around steadily by water pressure running through the gear sleeve assembly. The rotor head bearings are sitting on the arm of the rotor head enabling the rotor head to move freely.
 The flow tube nozzle is attached to the flow tube assembly. An opening is placed in the distribution head allowing water to flow freely.
 Water that is running through existing piping returns back to a swimming pool where the present invention is typically installed. This will allow the returning water to enter the wall fitting end cap and pass through the gear assembly and exit through the rotor head disbursing water on a continuing basis. An optional attachment to a fixed rotor head (by locking the rotating head in place to prevent rotation of the rotor head), allows water to return though the wall fitting, though the flow tube, flowing back into the swimming pool.
 It is understood that one skilled in the art may design several gear configurations so that the rotating nozzle turns at a desired rate accomplished by the example of gear configurations presented herein. Therefore, the gear/turbine design shown in the drawings should not be considered as limiting. Although the channeled flue at the inlet to the assembly is desirable to enhance the direction of the water flow against the turbine blades, it too is not necessary. A simple flue with a plurality of apertures in a pre-set array, including a perimeter array of apertures, will accomplish the objective. The angularly directed apertures however produce an enhanced effect. Similarly, the reduction gear assembly can also be accomplished using different arrays of gears, gear pitches and gear teeth. The gear reduction means shown in the drawings is merely one example for obtaining the desired performance of the inventive device.
 The total assembly can be made with a variety of materials including polymeric composite materials, metallic materials and combinations thereof.
 It should be understood that the preceding is merely a detailed description of one or more embodiments of this invention and that numerous changes to the disclosed embodiments can be made in accordance with the disclosure herein without departing from the spirit and scope of the invention. The preceding description, therefore, is not meant to limit the scope of the invention.
