Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a self-cleaning knob water faucet. More particularly, the present invention relates to a self-cleaning knob water faucet that includes dispensing means for automatically dispensing water onto the water faucet knob when the water faucet is in the open position. 
     Usually, the knobs of a water faucet can be become contaminated by detergents, toners, bacteria and the like. 
     When a person&#39;s hands have become dirty and they wish to have them washed clean, the knobs of the water faucets that are manually turned on by the person&#39;s dirty hands become dirty themselves. After the person has cleaned his dirty hands and proceeds to manually turn off the water faucets, the person&#39;s clean hands become dirty again. 
     Numerous innovations for human washing devices have been provided in the prior art that will be described. However, even though these innovations may be suitable for the specific individual purposes to which they address, they differ from the present invention in that they do not teach a self-cleaning knob water faucet that includes dispensing means for automatically dispensing water onto the water faucet knob when the water faucet is in the open position. 
     FOR EXAMPLE, U.S. Pat. No. Des. 331,277 to Murphy teaches a Y-shaped pipe for feeding water simultaneously to a pair of tandem shower heads. 
     ANOTHER EXAMPLE, U.S. Pat. No. 3,913,839 to Wilson teaches an attachment device for converting a single shower head personal shower installation to dual, opposed shower head installations to provide for showing at each side of the shower enclosure or recess in which the device is installed. 
     STILL ANOTHER EXAMPLE, U.S. Pat. No. 5,199,118 to Cole et al. teaches a hand sanitizing wash station that includes a sink, a soap dispenser located above the sink for supplying soap, a water dispensing faucet located above the sink operated by a solenoid valve, and a hot-air dryer located above the sink for supplying hot air. 
     YET ANOTHER EXAMPLE, U.S. Pat. No. 5,217,035 to Van Marcke teaches a washroom control system that automatically controls water valves and soap valves by infrared sensing of a user&#39;s hands, tests a battery to determine whether enough energy is stored to reliably close a valve, and generates an alarm if the battery needs replacing. 
     FINALLY, STILL YET ANOTHER EXAMPLE, U.S. Pat. No. 5,265,628 to Sage et al. teaches a hand washing system that includes nozzles rotating in a cylinder that through a program provides purge, wash, dwell, rinse, and self-clean cycles. 
     It is apparent that numerous innovations for human washing devices have been provided in the prior art that are adapted to be used. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, they would not be suitable for the purposes of the present invention as heretofore described.

     The longitudinally-oriented and externally-threaded metering assembly allen screw 272 of the internally-disposed metering assembly 261 is a non-corrosive material, such as but not limited, to plastic or the like. 
     The longitudinally-oriented and externally-threaded metering assembly allen screw 272 of the internally-disposed metering assembly 261 is moved relative to the longitudinally-oriented, centrally-disposed, and internally-threaded metering assembly throughbore 270 of the hollow, internally-disposed, open front, substantially closed top and bottom, and parallelepiped-shaped metering assembly enclosure 263 of the internally-disposed metering assembly 261. by the standard allen key 74. 
     The operation of the second embodiment of the self-cleaning knob water faucet 210 can best be seen in FIG. 4 and 5, and as such, will be discussed with reference thereto. 
     Water from a water source enters the hollow, open-ended, externally-threaded, and cylindrically-shaped faucet body lower portion 226 of the hollow faucet body 224 in the direction of water source arrows 300. 
     When the self-cleaning knob water faucet 210 is in the open position, water enters the hollow, open-ended, and slightly frustrum-shaped faucet body upper portion 242 of the hollow faucet body 224, in the direction of body water arrows 301. 
     Once the water enters the hollow, open-ended, and slightly frustrum-shaped faucet body upper portion 242 of the hollow faucet body 224, it is divided into two parts. 
     A first and larger part of the water enters the hollow, open-ended, and inverted J-shaped overhead faucet body arm 240 of the hollow faucet body 224, in the direction of arm water arrows 303. The spout water 16 exits the spout 18 in the direction of spout water arrows 304. 
     The remaining and smaller part of the water enters and passes through the longitudinally-oriented, centrally-disposed, and internally-threaded metering assembly throughbore 270 of the hollow, internally-disposed, open front, substantially closed top and bottom, and parallelepiped-shaped metering assembly enclosure 263 of the internally-disposed metering assembly 261. 
     The water passing through the longitudinally-oriented, centrally-disposed, and internally-threaded metering assembly throughbore 270 of the hollow, internally-disposed, open front, substantially closed top and bottom, and parallelepiped-shaped metering assembly enclosure 263 of the internally-disposed metering assembly 261 enters and passes through the hollow, open-ended, and cylindrically-shaped faucet body sprinkler housing 253 of the hollow faucet body 224, in the direction of shower water arrow 306. 
     The water passing through the hollow, open-ended, and cylindrically-shaped faucet body sprinkler housing 253 of the hollow faucet body 224 becomes the showering water 14 and self-cleans the knob 15. 
     To adjust the amount of water entering the internally-disposed metering assembly 261 and ultimately the amount of water that is going to clean the knob 15, the hollow and open-ended packing lock fitting 250 is loosened and the hollow, open-ended, and inverted J-shaped overhead faucet body arm 240 of the hollow faucet body 224 is removed from the hollow faucet body 224. 
     The allen key 74 is used to position the longitudinally-oriented and externally-threaded metering assembly allen screw 272 of the internally-disposed metering assembly 261 in the longitudinally-oriented, centrally-disposed, and internally-threaded metering assembly throughbore 270 of the hollow, internally-disposed, open front, substantially closed top and bottom, and parallelepiped-shaped metering assembly enclosure 263 of the internally-disposed metering assembly 261.
