     The present invention relates to dispensing devices. More particularly, the present invention relates to a soap dispensing device which is attached to a common kitchen faucet. 
     2. Description of the Prior Art 
     Generally, liquid soap dispensers a re remote or attached to the perimeter of a sink. The liquid soap dispensers function a user pushing a pump device or picking up the dispenser turning it over and squeezing it to eject liquid soap from a nozzle. These have significant disadvantages including wasting water while the user applies soap to an object while leaving the water running. Further, the perimeter mounted dispensers limit the location on the object the soap can be place because of the typically short length of the dispenser spout. What is desired is a liquid soap dispenser that attaches to the faucet of a standard kitchen faucet and cuts off the flow of water when the soap is dispensed. 
     Numerous innovations for liquid soap faucet dispenser have been provided in the prior art that are described as follows. Even though these innovations may be suitable for the specific individual purposes to which they address, they differ from the present invention as hereinafter contrasted.

     SUMMARY OF THE INVENTION 
     The present invention is a device which is attached to the end of a standard kitchen faucet and dispenses liquid soap on to an object to be washed. When dispensing soap the present invention cuts off the flow of water to permit the user and opportunity to wash the object and conserve water. The present invention is activated by rotating the device in a first direction which cuts off the flow of water and dispensed liquid soap. When the present invention is returned to the original position the water flow is restored and the dispensing of liquid soap is stopped. 
     The types of problems encountered in the prior art are a need to dispense liquid soap on to an object which is being washed in a kitchen sink. 
     In the prior art, unsuccessful attempts to solve this problem were attempted namely dispensers mounted around the perimeter of a sink or specially adapted faucets having a dispensing mechanism built in. Additionally, complex mechanisms were proposed which would be very costly to install. However, the problem was solved by the present invention because the present invention installs onto the end of the faucet with out further modification. The present invention operates with simple rotation of the device to a dispensing position then return to a closed position. 
     The present invention solved a long felt need for a simple device capable of dispensing soap onto a dish which is being washed in the sink of a kitchen. 
     Accordingly, it is an object of the present invention to provide a soap dispenser which also control the water flow from a faucet and dispenses soap in the middle of a sink. 
     More particularly, it is an object of the present invention to provide a water flow control which maintains the water temperature initially set with the hot and cold valves. 
     In keeping with these objects, and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a faucet body having a faucet adapter which attaches in a complementary fashion to a faucet end. 
     In accordance with another feature of the present invention, a faucet water pressure reducer lowers the water pressure going to the faucet adapter. 
     Another feature of the present invention is that soap is dispensed via gravity feed. 
     Yet another feature of the present invention is that a soap dispenser adapter soap adjuster controls the amount of soap released through a soap dispenser soap tube. 
     Still another feature of the present invention is that a soap dispenser outlet which alternatively discharges soap and water downwardly. 
     Yet still another feature of the present invention is that a soap dispenser reservoir is filled by pouring soap through a soap dispenser reservoir opening. The soap is retained within the reservoir by a soap dispenser reservoir opening cap which closes the soap dispenser reservoir opening. 
     Still yet another feature of the present invention is that faucet adapter functions to removably attach the liquid soap faucet dispenser to a faucet. 
     Another feature of the present invention is that faucet adapter has a faucet water pressure reducer which lowers the incoming water pressure before it flows through the soap dispenser outlet. 
     Yet another feature of the present invention is that a faucet valve, located inside the faucet body causes soap to be dispensed when the soap dispenser is rotated from an initial horizontal position to a vertical position. At the same time water flow is cut off. When the soap dispenser is rotated from the vertical position to the horizontal position soap dispensing stops and the water flow is restarted. 
     Still another feature of the present invention is that a faucet valve spring is retained on one end by a faucet valve adjustment nut and a faucet valve lock nut this arrangement provides for adjustment of the spring pressure applied to the valve seat. 
     Yet another feature of the present invention is that hygiene control is improved because soap is readily available and easy to access when a person is washing his hands. 
     The novel features which are considered characteristic for the invention are set forth in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of the specific embodiments when read and understood in connection with the accompanying drawings.
