Field of Invention The present invention relates to a tap assembly and, more particularly, to a tap head with pull-out capability and multiple fluid outlet patterns available through multiple selectively operated valves. Background of the Invention Faucet-mounted spray heads are used in many residential, industrial, and commercial settings and perform many functions. Spray heads can be mounted on conventional faucets or on faucets with additional features. Some example features include various temperature and fluid control options, the ability to pull the spray head out, and multiple spray patterns. Some spray heads offer multiple spray patterns, but often require two-handed movement of spray discs or radial cables to manipulate the spray head into different spray modes. Still others offer only an aerated stream and a spray stream. Earlier spray head designs achieved some of these functions, but required many parts and were larger and heavier. Therefore, there is room for improvement in the art. Consequently, it is desirable to offer a spray head with new functionality in a small, lightweight, and attractive package that is easy to use and readily attaches to many taps or similar installations. Summary of the Invention The present invention provides a tap pull-out head, which includes a housing, a fluid diversion system, and a multi-pattern head. The fluid diversion system includes a series of channels, courses, or flow passages and first and second valves to selectively direct fluid communication through the pull-out head. The first valve is arranged in a first valve body and is switchable between a first position and a second position. The first valve body has a first orifice, a second orifice, and a third orifice. The second valve is arranged in a second valve body between a third position and a fourth position. The second valve body has a fourth orifice, a fifth orifice, and a sixth orifice. A first channel or stroke has a first inlet end adapted to be in fluid communication with a water supply or course and a first outlet end fluidically connected to the first orifice of the first valve body. A second channel or stroke has a second inlet end fluidically connected to the second orifice of the first valve body and a second outlet end adapted to discharge a fluid. A third channel or stroke has a third outlet end fluidically connected to the fourth orifice of the second valve body. A fourth channel or stroke has a fourth inlet end fluidically connected to the fifth orifice of the second valve body and a fourth outlet end adapted to discharge a fluid. When in the first position, the first valve seals the third orifice of the first valve body. When in the second position, the first valve seals the second orifice of the first valve body. When in the third position, the second valve seals the sixth orifice of the second valve body. When in the fourth position, the second valve leaves the fourth, fifth, and sixth orifices open. Thus, the first valve is operable to select between the first and second output patterns, and the second valve is operable to modify the second output pattern. Additional areas of applicability of the present invention will become apparent from the detailed description provided herein. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are for illustrative purposes only and are not intended to limit the scope of the invention.

Detailed Description of the Preferred Embodiment The following description of the preferred embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application or uses. With reference to Figure 1, a multi-pattern spray head with pull-out design of the preferred embodiment of the present invention is generally indicated by the reference numeral 10. The spray head 10 of the preferred embodiment of the present invention is configured to be a pull-out spray head mounted on a tap body 50. With flow control valves 52, the tap 50 provides temperature control and flow regulation of a fluid, most notably water, to the spray head 10. Anyone skilled in the art will readily appreciate that the spray head 10 can be attached to other water sources, two exemplary water sources being a garden hose (not shown) and a tap with hot or cold water service only (not shown). With reference to figures 2 and 3, the pull-out spray head 10 includes a housing. 12, a fluid diversion system 14 and a multi-pattern head 16. The housing 12 further includes a cover 18, a switch cover assembly 20, a rocker switch assembly 22, a sliding switch assembly 24 and the corresponding notch 26. The cover 18 additionally includes a housing 54, an enclosure 56 and mounting surfaces 58. The housing 54 has an exterior 54a and an interior 54b and the casing 56 has a left side 56a and a right side 56b. The left side 56a and the right side 56b. The left side 56a and the right side 56b of the casing 56 are connected to the exterior 54a of the casing. Someone skilled in the art will readily appreciate that there are several methods for attaching the wrapper 56 to the wrapper 54. For that purpose, the method for attaching or affixing the wrapper 56 to the wrapper 54 may have to withstand high humidity, excess moisture, cleaning agents, degreasers, and skin oils. The wrapper 56 must not only withstand the conditions in which the spray head 10 is installed, but must also be easily maintained with a consumer-pleasing appearance. The interior 54b of the housing 54 includes mounting surfaces 58 (not all of which are shown) configured to support the fluid bypass system 14 when inserted into the housing 12. The fluid bypass system 14, explained in detail below, is inserted into the housing 12 and held in place by the support of the mounting surfaces 58, so that the fluid bypass system 14, in general, does not move in relation to accommodation 12. With reference to figures 2, 3 and 6, the commutator cover assembly 20, which includes the oscillating commutator assembly 22 and the sliding commutator assembly 24, forms a separate structure attached to the housing 12 after the fluid diversion system 14 is inserted into the housing. 12. The switch cover assembly 20 includes an input end 20a and an output end 20b. Anyone skilled in the art will readily appreciate that the labels inlet end and outlet end do not limit the commutator cover configuration to a geometry having two distinct ends: one of that geometry being a circle. As such, inlet end 20a defines a portion of the commutator cover assembly 20, which is relatively closer to the housing inlet 28 compared to outlet end 20b which is closer to the multi-pattern head 16. The labels inlet end and outlet end, therefore, do not serve to limit or define the geometry of an item, but facilitate discussion of the item by designating its relative location. Inlet end and outlet end, therefore, can be used to discuss other components of the spray head 10 with the same definition of location designation in mind. With particular reference to figures 2, 3, 6 and 7, the switch cover assembly 20 still includes a mounting element 60, defining a first opening. 62, a fastener 64, a mounting location 66, defining a second opening 68 and an elliptical opening. 70. Adjacent to the inlet end 20a of the commutator cover assembly 20, the mounting element 60 bridges a first inner edge 72a to a second inner edge 72b of the elliptical opening 70. The fastener 64 passes through the first opening 62 and finally fastens the commutator cover assembly 20 to the second opening at the mounting location 66 located in the fluid bypass system 14. The rocking switch assembly 22 includes a column clamp 74, a bar clamp 76, a tongue 78, a lever 80 with a thumb depression 82, and a first spring 84. The rocking switch assembly 22 is located within the elliptical opening 70 and rocks around a pivot axis that is generally perpendicular to a longitudinal axis of the housing 12. The column clamp attached to the lever 80 is removablely coupled to an external first column 86 of the first valve assembly. 34. The bar clamp 76 is also attached to the lever 80 and is removablely coupled to a bar 88. The bar 88 is attached to a bar support 90. The bar 88, the bar support 90, the first outer column 86, and the first valve assembly 34 are constituents of the fluid diversion system 14; as such, they are discussed later in greater detail. The tongue 78 is attached to the outer perimeter of an entry end 80a of the lever 80. The tongue 78 is configured to fit below a third outer edge 72a of the elliptical opening 70. An exit end 80b of the lever 80 defines the depression for the thumb. 82, which, when compressed, swings the lever 80 towards the multi-pattern head 16. When the lever 80 swings towards the multi-pattern head 16, the output end of lever 80b moves downwards in order to compress the first spring 84 and compresses the first outer column 86 in the first valve assembly 34. The input end of lever 80a moves upwards so that the tab 78 contacts the third inner edge 72c of the elliptical aperture 70. With reference to figures 2, 4a and 4b, the sliding switch assembly 24 is located near the outlet end 20b of the switch cover assembly 20. The sliding switch assembly 24 further includes a slider 92, having a ramp 94 and a rail 96. The slider 92 is inside the rail 96. The ramp 94, formed in the slider 92, is configured to push a second outer column 98 in the second valve assembly 38, when the side 92 is slid from a first location 92a to a second location 92b, that is, in a direction perpendicular to the longitudinal axis of the housing 12. The second outer column 98 and the second valve assembly are constituents of the fluid diversion system 14; As such, they are discussed in greater detail later. The tap 50, in the preferred embodiment of the present invention, is configured to engage the corresponding notch 26 of the housing 12. The engagement of the corresponding notch 26 prevents the rotation of the spray head 10 when mounted on the tap 50. Anyone skilled in the art will readily appreciate that the spray head 10 remains operable whether the corresponding notch 26 is engaged or disengaged from the tap. Referring now to Figures 3 and 8, the fluid diversion system 14 includes the housing inlet 28, the first stroke 30, the second stroke 32, the first valve assembly 34, the third stroke 36, the second valve assembly 38, the fourth stroke 40, and the fifth stroke 42. The first stroke 30 fluidically connects the inlet 28 to the first valve assembly 34. The second stroke 32 fluidically connects the first valve assembly 34 to the current outlet assembly 44 of the multi-pattern head 16. The third stroke 36 fluidically connects the first valve assembly 34 to the second valve assembly 38. The fourth stroke 40 fluidically connects the second valve assembly 38 to the first annular outlet assembly 46 of the multi-pattern head 16. The fifth stroke 42 fluidically connects the second valve assembly 38 to the second annular outlet assembly 48 of the multi-pattern head. 16. Current output assembly 44, the first annular output set 46 and the second annular output set 48 are constituents of the head of multiple patterns 16; as such they are discussed later in greater detail. The housing inlet 28 generally has a cylindrical shape and communicates a fluid from an inlet end 28a to an outlet end 28b, as seen in Figure 3. The inlet end 28a is configured to connect to a conventional water supply line 100. As shown in Figure 1, the water supply line 100 is a hose 102 from a pull-out tap 50, which connects to the inlet end 28a using conventional screw threads (not shown). Anyone skilled in the art will readily appreciate that the water supply line 100 can take many other forms: two such exemplary forms include a fixed tap without pull-out function (not shown) or a conventional garden hose (not shown).In addition, the input end 28a can be connected using other suitable connecting devices or by introducing an additional connecting device, such as a quick-disconnect coupler (not shown). The outlet end 28b of the housing inlet 28 includes a first sealing gasket 104. The outlet end 28b is configured to connect to an inlet end 30a of the first stroke 30, using conventional screw threads (not shown). When the housing inlet 28 is attached to the first stroke 30, the first sealing gasket 104 engages the interior 54b of the housing. 54. The fixing of the housing inlet 28 of the first stroke 30 secures the fluid bypass system 14 inside the housing 12, so removing the fluid bypass system 14 from the housing 12 requires removing the housing inlet 28 of the first stroke 30. The first stroke 30 generally has a cylindrical shape and delivers fluid from the inlet end. 0a to an outlet end 3 0b. The inlet end 30a includes a second sealing gasket 106 and connects to the outlet end 28b of the housing inlet. 28. The outlet end 3 0b of the first stroke 3 0 is configured to connect to a first orifice 108 of the first valve assembly 34. The first course 30 still includes mounting location 66, the second opening 68, the bar 88, and the bar support 90. Mounting location 66 is configured so that the fastener 64 secures the switch cover assembly 20 of the housing 12 to mounting location 66 by fitting the fastener 64 into the second opening 68. The bar support 90 is configured to retain the bar 88, so that the bar clamp 76 of the sliding switch assembly 24 connects to the bar 88. With specific reference to figures 8 and 9, the first valve assembly 34 still includes the first orifice 108, a second orifice 110, a third orifice 112, a first sealing body 114, a first position 116 (shown in figure 18), a second position 118 (shown in figures 16 and 17), a first body 120, the first outer column 86, a first body cover 122, a first shaft 124, a third sealing gasket 126, a fourth sealing gasket 128 and a fifth sealing gasket 130. The first shaft 124 connects the first sealing body 114 to the first outer column 86. The first shaft 124 passes through the first body 120, the first body cover 122 and the third sealing gasket. 126. The first body cap 122 captures the third sealing gasket 126 in the first body 120. While the first valve body 114 and the first outer column move with the first shaft 124, the third sealing gasket 126 slides onto the first shaft 124 but remains captured within the first body. 120. With reference to figures 9, 16, 17 and 18, the movement of the first shaft 124 through the first body 120 defines the first position 116 and the second position 118 of the first valve assembly 34. The first position 116, therefore, is defined by the first valve body 114, located in the lower position within the first valve assembly. 34. Correspondingly, the first outer column 86 is now relatively further from the first body cap 122, when compared to the first outer column 86 in the second position 118. The second position 118, therefore, is defined by the first sealing body 114 located in the upper position within the first valve assembly 34. Correspondingly, the first outer column 86 is in the second position 118. The second position 118 is therefore defined by the first sealing body 114 located in the upper position within the first valve assembly 34. Correspondingly, the first outer column 86 is now relatively closer to the first body cover. 122, when compared to the first outer column 86 in the first position 116. The first orifice 108 is fluidically connected to the outlet end 30b of the first stroke 30; as such, the first orifice 108 is configured so that the fluid enters the first valve assembly 34 through the first orifice 108. In turn, the second orifice 110 and the third orifice 112 are configured so that the fluid exits the first valve assembly 34 either through the second orifice 110 or through the third orifice 112, depending on the position of the first valve assembly 34. The second orifice 110 is connected to an inlet end 32a of the second stroke 32. The third orifice 112 is connected to an inlet end 36a of the third stroke 36. In the first position 116, the first valve assembly 34 is configured so that the fluid enters the first valve assembly 34 through the first orifice 108 and exits through the second orifice 110. As such, the first sealing body 114 in the first position 116 seals the third position 112. In the second position 118, the first valve assembly 34 is configured so that the fluid enters the first valve assembly 34 through the first orifice 108 and exits through the third orifice. 112. As such, the first valve body 114 in the second position 118 seals the second orifice 110. The first valve assembly 34 is further configured so that the forces exerted by the fluid pressure within the spray head 10 maintain the first valve assembly 34 in the first position 116. In addition to the forces exerted by the fluid within the spray head 10, the first spring 84 is configured to hold the first valve assembly 34 in the first position 116. The first spring 84 is disposed between the first body cover 122 and the lever 80 of the sliding switch assembly 24. Disposed within the first spring 84 is the first outer column 86 to which the column retainer 74 of the lever 80 is attached. Compression of the lever 80 compresses the first spring 84 and actuates the first shaft 124 to its upper position within the first valve assembly 34, causing the first valve assembly to change from the first position 116 to the second position 118. With lever 80 no longer compressed, the first spring 84 returns to its normal position; so that lever 80 moves away from the first body cover 122. For that purpose, the column retainer 74 of lever 80 pulls the first outer column 86, which results in the first housing 124 returning to its lower position. Thus, with lever 80 no longer compressed, the first valve assembly 34 returns to the first position 116. The first body, 12 oz, is configured so that it is an independent component from the first valve assembly. 343 and can be inserted and removed as needed. This configuration allows for the installation, servicing, and inspection of the components of the first valve assembly 34. The fourth sealing gasket 128 and the fifth sealing gasket 130 are placed along the periphery of the first body. 120 and serve to seal the first body 120 inside the first valve assembly 34, when installed. With specific reference to figures 10, 11 and 12, the second stroke 32 generally has a curved cylindrical shape and communicates a fluid from the inlet end 32a to an outlet end 32b. The curved cylindrical shape of the second stroke 32 generally follows the contours of the housing 12 between the inlet end 32a and the outlet end 32b. The inlet end 32a connects to the second orifice 110 of the first valve assembly 34. The outlet end 32b connects to the current outlet assembly 44 of the multi-pattern head 16. The third valve 36 has a cylindrical shape and communicates a fluid from the inlet end 36a to an outlet end 36b. The inlet end 36a connects to the third port 112 of the first valve assembly 34. The outlet end 36b connects to a fourth port 132 of the second valve assembly 38. With reference to figures 11, 12, 16, 17 and 18, the second set of valves 38 still includes the fourth column. 132, a fifth hole 134, a sixth hole 136, a second user sealing body 138, a third position 140, a fourth position 142, a second valve body 144, the second outer column 98, a second body cap 146, a second shaft 148, a second spring 150, a second sealing gasket 152, a seventh sealing gasket 154, and an eighth sealing gasket 156. The second shaft 148 connects the second sealing body 138 to the second outer column 98. The second shaft 148 passes through the second valve body 144, the second body cap 146, and the sixth sealing gasket 152. The second body cap 146 captures the second sealing gasket 152 in the second valve body 144. While the second sealing body 138 and the second outer column 98 They move with the second shaft 148, the sixth sealing gasket 152 slides onto the second shaft 148, but remains trapped inside the second valve body 144. The movement of the second shaft 148 through the second valve body 144 defines the third position 140 and the qp. 140 and the fourth position 142. The third position 140, therefore, is defined by the second sealing body 138 located in the lowest position within the second valve assembly 38. Correspondingly, the second outer column 98 is now relatively further from the second body cap 149, when compared to the second outer column 98 in the fourth position. The fourth position 142, therefore, is defined by the second valve body 138 located in the highest position within the second valve assembly 38. Correspondingly, the second outer column 98 is now relatively closer to the second body cap 146, when compared to the second outer column 96 in the third position 140. The fourth orifice 132 is fluidically connected to end 36b of the third stroke 36; as such, the fourth orifice 132 is configured so that fluid enters the second valve assembly 38 through the fourth orifice 132; in turn, the fifth orifice 134 and the sixth orifice 6 are configured so that the fluid exits the second valve assembly 38 from the fifth orifice 134, from the sixth orifice 136, or from the fifth orifice 134 and the sixth orifice. 136, depending on the position of the second set of valves. The fifth hole 134 is connected to an input end 40a of the fourth stroke 40. The sixth hole 136 is connected to an input end 42a of the fifth stroke. In the third position, 140, the second set of valves. 8 is configured so that the fluid enters the second valve assembly 38 through the fourth orifice 132 and exits through the fifth orifice 134. As such, the second sealing body 138 seals the sixth orifice 136. In the fourth position 142, the second valve assembly 38 is configured so that the fluid enters the second valve assembly 38 through the fourth orifice 132 and exits through the fifth orifice 134 and the sixth orifice 136. As such, the second sealing body 138 does not seal the fourth orifice 132, nor the fifth orifice 134, nor the sixth orifice 136. The second valve assembly 38 is configured so that forces exerted by the fluid pressure within the spray head 10 maintain the second valve assembly 38 in the third position 140. In addition to the forces exerted by the fluid within the spray head 10, the second spring 150 is configured to maintain the second valve assembly 38 in the third position 140. The second spring 150 is attached to one end 98a of the second outer column 98 and is thus arranged between the second body cover 146 and the second outer column 98. The ramp 94 of the cursor 92 is configured so that moving the cursor 92 from the first location 92a to the second location 92b compresses the second spring 150 and actuates the second shaft 148 to its upper position within the second valve assembly 38. As such, the second valve assembly 38 changes from the third position 140 to the fourth position 142 when the cursor 92 is moved from the first location 92a to the second location 92b. The movement of the oscillating switch from the second location 92b returning to the first location 92a allows the second spring 150 to return to its normal position, thus pushing the second outer column 98 away from the second body cover 146. 0 second valve assembly 38, therefore, returns to the third position 140. The second valve body 144 is configured so that it is an independent component of the second valve assembly 38 and can be inserted and removed as needed. This configuration allows for the installation, servicing, and inspection of the components of the second valve assembly 38. The seventh sealing gasket 154 and the eighth sealing gasket 156 are seated along the periphery of the second valve body 144 and serve to seal the second valve body 144 within the second valve assembly 38 when installed. The fourth stroke 40 generally has a curved cylindrical shape and communicates a fluid from the inlet end 40a to an outlet end 40b. The curved cylindrical shape of the second stroke 32 generally follows the contours of the housing 12 between the inlet end 40a and the outlet end 40b. The inlet end 40a connects to the fifth orifice 134 of the second valve assembly 38. The outlet end 40b connects to the first annular outlet assembly 46 of the multi-pattern head 16. The fifth stroke 42 generally has a cylindrical shape and communicates a fluid from the inlet end 42a to an outlet end 42b. The inlet end 43a connects to the sixth orifice 136 of the second valve assembly 38. The outlet end 42b connects to the second annular outlet assembly 38. As noted above, when the second valve assembly 38 is in the fourth position 142, fluid is circulating through the fifth stroke. 42 and through the fourth course 40. As described above, the present invention utilizes two sets of valves to select the operating modes of the spray head. Specifically, the first set of valves 34 is operable to select between a stream mode and a spray mode, while the second set of valves 38 is operable to modify the spray mode from a single standardized spray mode to a multiple standardized spray mode. However, one skilled in the art will recognize that the present invention can be adapted to provide other modes of operation. For example, the first valve assembly could employ a multi-position valve (i.e., more than two) to provide a stream / spray mode or an off mode. Similarly, the second valve assembly could be designed to provide different spray modes based on the selected position. Furthermore, additional valve assemblies could be incorporated into the spray cable to increase the number of available spray head modes. Various flow paths or orifices could also incorporate throttling to configure the flow pressure and flow rate of fluid displacement through them. The present invention considers the modifications described above. With reference to figures 2 and 13-15, the multi-pattern head 16 includes the current output assembly. 44, the first annular outlet assembly 46 and the second annular outlet assembly 48. The stream outlet assembly includes a reservoir 158, an aerator assembly 160, a ninth sealing gasket 162, a tenth sealing gasket 164 and a retaining fin 166. The aerator assembly 160 of the current outlet assembly 44 also includes an aerator housing 176, a first screen 178, a second screen 180, a screen ring 182 and a slot 184.
