     STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT. 
       [0002]    N/A 
       BACKGROUND OF THE INVENTION, PET FOUNTAINS AND REVIEW OF THE PRIOR ART 
       [0003]    It is believed that the first pet fountain was a product called Kitty Kreek which was perhaps advertized as early as 1995. The initial benefit for a pet fountain was thought to stimulate the water consumption by attracting a pet to the water supply with the sight and sound of falling water. While there is no evidence of falling water stimulating water consumption in nature, the advertizing claim did motivate pet owners to buy something for their beloved pet to replace a simple bowl of room temperature tap water. Initially, the most successful fountain was called The Drinkwell which cashed in on the purported preference of cats wanting to drink water falling from a dripping or running household faucet. The inventors of the Drinkwell received the U.S. Pat. No. 5,799,609, which was issued in September 1998 covering the concept of “Free Falling Water”. A request for reexamination of the &#39;609 patent was accepted in July 2010. 
         [0004]    Dozens of competing pet fountains were sold attempting to provide attractants that might cause a pet to drink more water. Due to consumer complains, almost all fountains added a refill design to their original design to offset the water lost to evaporation, spilling and consumption of the water. To date, most, if not all, refill designs were made of plastic which were very difficult to keep clean due to the porous nature of the plastics and the awkward and inaccessible angles within the refill containers. The methods to cause water to flow from the refill container to the open container caused many problems with water overflowing onto the floor because the moving part of the flow design would often become stuck in the open position due to the mechanism being damaged in the normal course of adding water to the refill container or the mechanism becoming impaired due to water impurities such as calcium deposits or the buildup of algae or the effect of cleaning measures such a chlorine bleach or heat. The customer feedback concerning overflow reported on websites such as Amazon caused many customers to throw out their fountains in just a few months so to avoid the more serious dangers of slip and fall, damaging expensive wood floors or electrocution. 
         [0005]    The common sense issue of chilling the water to below ambient temperature to increase the water consumption has been attempted by adding ice cubes or by freezing the water within the refill container. The practice of adding ice cubes to reduce the water temperature usually had a limited and short term effect and is very impracticable when the owner works outside the home or takes a weekend trip. Freezing the refill container was found to damage the refill container as well as the flow restricting mechanism requiring replacing the refill system which could cost as much as the entire fountain. 
         [0006]    The dynamics of causing the flow of the water so as to initially attract a pet and then cause a pet to drink was limited by the patent claims of the &#39;609 so the other makers usually made their flow of water not to “free fall” but to be in constant contact with the materials used to manufacture the fountain and therefore causing the water to slide down a ramp rather than fall. The owners of the &#39;609 aggressively attacked almost every would-be competitor. The owners of the &#39;609 patent did not license their “free falling” claim so almost all other products were self limited to having their water quietly slip down a ramp into the pet accessible container which was located below the elevated water area. The amount of flow for most products was adjustable by placing flow restrictors in front of the intake area of the pump which often caused an unacceptable amount of pump noise due to cavitation. No product provided any means of adjusting the direction of the flow. 
       BRIEF SUMMARY OF THE INVENTION 
       [0007]    In accordance with one embodiment a platform that spans over a water supply that supports a sterilizable refill system while also providing various openings and structures that can produce a continues flow of cold, filtered, medicated and sterilized water for a pet. 
       ADVANTAGES 
       [0008]    An electrically non conductive and easily removed platform that can span all or part of a container of water or be attached to an outside wall and then hung over an open container of water and said platform can support and provide 
         [0009]    1. Support for one or more sterilizable and economically replaced glass refill bottles that can refill the water consumed by animals or lost to evaporation 
         [0010]    2. A Yorker spout that is modified so as to provide a quiet and safe method of adding water to the container while also preventing noise and preventing a potential overflow because of the angled modification. 
         [0011]    3. Support for a product such as an Ice Probe™ sold by NovaTec™ can be placed in any one of the available holes so as to chill the water below the ambient air temperature. 
         [0012]    4. A system of tubing that pulls water from the container and then pumps the water to distant areas of cold temperatures such as a refrigerator, freezer or even a toilet tank and then inserting tubes that are highly thermally conductive, such as copper, the water coming from the container is cooled in the colder environment and then returned to the container much colder than when the water left the container. 
         [0013]    5. A support for a closed system of flexible tubing that removes water from the container via a common aquarium pump and then pumps the water through the cold side of a thermoelectric device which has been formed so that a tube of highly thermally conductive material, such as copper, can be sandwiched between two plates that are part of the cold side of a thermoelectric chilling device using what is commonly called the Peltier effect to cause the cooling effect usually using a common water block, heat sink or heat exchanger. 
         [0014]    6. A location to place an empty tube that is closed on the end and that the closed end can sit into the water in the container and be filled with cold materials such as ice cubes into the open end to cool the water in the container without adding water to the container as the ice melts. 
         [0015]    7. A platform to allow various methods to sterilize the water that naturally flows by due to the relative distant locations of the intake and outflow of one or more pumps or the sterilization method such as UV light can be inline using one or the pumps to create a flow through the UV light much like the inline sterilizing products used to keep aquarium water microbiologically clean. 
         [0016]    8. A platform to hold, horizontally, and anchor a tube filled with charcoal or other filter material with an elbow at the distal end that is adjustable from pointing straight up, for the maximum in noise and stream of water, to straight down, for the quietest water noise and least potential for splashing, or at any angle between or direction in a single plane of 360 degrees. 
         [0017]    9. a platform where a hole can be utilized to anchor a tube filled with charcoal or other filter media in a vertical position and the elbow can be moved to direct the stream of water away from the centerline or a tube can be affixed to the end of the elbow to direct the flow into the water with little, if any, splash or noise. 
         [0018]    10. A platform that anchors a very small pump that pumps water from the container and then through the high temperature side of a thermoelectric device and or the transformer/ power supply used to change 110 v or 220 v to the required 12 v to operate the thermoelectric chiller, so that at a minimum time exposure is at least 16 seconds at 72° C. or other effective time and temperature, so most all microorganisms will be destroyed. 
         [0019]    11. A platform that can be easily lifted off or rotated to the rear or to the side with one or more or all of the devices being also lifted off in the process so that the water container may quickly and easily be effectively cleaned or sterilized. 
         [0020]    12. A platform that can support a bag like container at or below the water level which contains medications or other chemicals that can be delivered to the water supply.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0028]    One embodiment shown in  FIG. 1  is  150  is a free-standing platform structure that supports various devices to clean, cool, sterilize and furnish replenishment water for a pet fountain. Further in  FIG. 1  is  110  which is a hole that has been cut or molded in the material that forms  150 . The hole may be cut in the material that makes  150  in a secondary operation, or  110  could be part of the mold that could make  150 .  110  can support many embodiments, such as an Ice Probe™ chiller (sold by NovaTec of San Rafael, Calif.)  210 B and a Yorker spout cap  230  while when combined with a bottle  240  can provide a refill supply of water in a quiet manner and without the possibility of the water from the bottle  240  rushing out and flooding the surface below the pet fountain. Further,  110  has other uses, such as holding a ultra-violet sterilizer lighting tube that passes through  110  into the container of water, which  630  is just one possible configuration for the container of water.  110  can also be used as a pass-through for tubing from  530  and/or  520 . 
         [0029]    The hole  110  also is meant to hold  230 , which is a Yorker spout and cap combination that has been trimmed by the sharp 90 degree angle of hole  110 , and also trim the ribs,  310 B, of  310 . The trimming of  310 B is accomplished by having the hole  110  cut or molded at a precise 90-degree angle in material that is structurally strong enough to modify or trim the ribs  3108 , thereby forming a tight seal and preventing instability when a bottle  240  is threaded into the cap portion of  230  and filled with water. 
         [0030]      FIG. 1  also shows  120  which is a structure intended to stabilize the front of  220  which is a tube filled with charcoal or other filtering media, by the use of a strapping material inserted through one of the many available slots of  120 . Presently, the  120  object is distributed by Home Depot and is labeled on the package as stock number 296167 with a nomenclature of a Mounting Device.  FIG. 1  also shows  130  which is the rear anchoring hole for the rear elbow of the filter  220 . Also shown in  FIG. 1  is  140  which is a semi-circle or slot or notch meant to anchor or restrict movement of an electrical cord such as when a submergible pump is put in the bottom of a water container, one embodiment of which is  630 . The  140  opening is also a good place to serve as a pass through for the tubing coming from and returning to the devices  520  and  530  as shown in  FIG. 5 . 
         [0031]      FIG. 2  shows the location and orientation of the thermoelectric chiller (“TEC”), labeled as  210  presently supplied by NovaTec of San Rafael, Calif., that is mounted in one of the holes  110  of the part labeled as  150 . The probe  210  passes through the hole  110  and rests in the water of whatever container is below the top of platform  150 . Also in  FIG. 2  is  230  which is a spout and cap combination commonly known as a Yorker cap and spout which has been modified as shown as  FIG. 3  and which is seated into hole  110  in such a manner that the ribs of  310 B are gently trimmed to form a very stable combination. To attempt to avoid any confusion, the cap and spout labeled as  230  is different from the cap and spout labeled as  310  in that the trimming and seating resulting from pushing the  310  into  110  will trim off the tops of most if not all of the ribs in the undulating design that encircles the cap portion of the cap and spout. The item  230  also has been modified as shown in  310 A. The  230  cap and spout are easily removable for other purposes such as being used as a pass through for cold and/or hot water harvested from the  520  and/or  530  using a device that has many names such as a water block or heat sink or heat exchanger all of which are commonly available via the internet and one supplier is cite number  6  in the form  10 - 6 B.  FIG. 2  also shows an inverted bottle  240  and is threaded into  230 . In  FIG. 2 ,  220  is a carbon filter horizontally mounted on the top of platform  150  which includes an elbow that is not fixed and fully adjustable to any angle in one 360-degree plane. 
         [0032]      FIG. 3  is a Yorker spout and cap, originally manufactured by Yorker Packaging of Greenville, S.C. (also drawn in cite number 8 of form 10-6B) with an angle,  310 A cut across the spout portion of  310  and the angle created prevents the overfilling of the water container as well as quieting the noise of water leaving the bottle  240  into the container below.  FIG. 3  also shows  310 B which is an undulating system of plastic ribs that has a diameter that is 0.03 inches larger (as shown in cite number 8 of form 10-6B) than the diameter of hole  110  so that when the soft plastic used to manufacture  310  and the resulting  310 B is inserted into the hole  110 , the rigid material used to manufacture  150 , such as 3/16″ ABS plastic, will trim the raised portion of the ribs  310 B and thereby provide a stable platform when the glass, or plastic bottle  240  is filled with tap water, distilled water or therapeutic water. 
         [0033]      FIG. 4  is a drawing of  150  without one leg when it becomes advantageous to permanently mount the top of the platform and all attendant features which is accomplished by using the holes  410  to mount the shelf permanently, such as a wall or cabinet, as shown in  FIG. 4 . 
         [0034]      FIG. 5  is a drawing showing an extension,  540 , on the rear of  150  which provides an enclosure to prevent water, dust or access by pets to numerous electronic components including, but not limited to, a TEC  530  and the power supply  520  to support the operation of  530 .  FIG. 5  includes many fitting areas such as  550 ,  560 , and  570  which are to harvest cold water that will be deposited into the water container and also harvest the heat from both  530  and  520  into a micro-bore array that will sterilize the circulating water that will be returned to the water container. In  FIG. 5 , there are two items labeled  510  which are the left and right walls shown in  150 , with the only difference being the extension  540 . 
         [0035]      FIG. 6  shows how the free standing platform  150  would look if the water container was a separate rectangular-shaped container to hold drinking water. There is a space that is intentionally created by having the span of  150  be greater than the width of the water container, in this case  630 , thereby allowing air flow and the resultant cooling effect due to the evaporation of sweat from the water container because the temperature of the water contained in the water container will be less than the ambient room temperature. Another useful embodiment is to locate electronic devices such as a TEC  530  and its power supply  520  and perhaps additional inline pumps under the water container so long as these items are protected from any water spilling over the side of the water container or from the water container sweating as well as isolating the components from pets and children. 
         [0036]      FIG. 7  is a cross section, Z-Z, showing the relationship of the hole,  110 , with the inverted modified Yorker,  230 , and the inverted bottle,  240 , threaded into  230  and also where the water level would normally be when the platform,  150 , is spanning a container,  630  (in this example). 
       Operation of the Pet Fountain Shown in FIG.  1  through  6   
       [0037]    The first step for the pet owner to do is to fill the water container, in this case  630 , with water to within “A” from the lip of the wall. At this point, the owner will place a submergible pump at the bottom of the water container so that a vertically-oriented outlet will enter through  130  and frictionally mate into the rear elbow of  220 . In a useful embodiment, the tubing  550 ,  560  and  570  that contain harvested cold or hot water, plus the return water tubing, as the devices  520  and  530  are self contained, would be already anchored in notch similar to  140 , allowing the simultaneous sterilization and chilling of the water that was pumped from the container, through the heat sink/water block/heat exchanger and then returned to the container in a closed loop. At this point, one or more of the refill bottles would be filled with water and inverted and threaded into the cap-spout combination  230 . Finally, all the electrical powered components would be turned on.
