     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 11 thereof, a new and improved shower head apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the shower head apparatus 10 of the instant invention essentially comprises a rigid conduit wand 11 that includes respective first and second fluid conduits 12 and 13 directed therethrough, with the first fluid conduit 12 directing heated water therethrough, with the second conduit 13 directing unheated water therethrough. The water through the first fluid conduit 12 is directed through a first annular conduit 14 (see FIG. 3) that is directed in an annular manner about the spray head 15 that is orthogonally oriented relative to the wand 11. The first annular conduit 14 (see FIG. 7) is directed in a cylindrical manner about a peripheral portion of the head 15 and in communication with a cylindrical outer channel 16 that directs a continuous heated water spray through an annular array of first outlet ports 17 (see FIGS. 1, 3, and 7). The spray head 15 includes a generally planar spray head face 18, wherein the direction of fluid from the spray head 15 is orthogonally oriented relative to the planar face 18. The outer cap housing 19 includes the annular array of outlet ports 17 to secure the outer cap housing 19 relative to the head 15, in a manner as illustrated in FIGS. 3 and 7. 
     A central cap housing 20 is rotatably mounted within the spray head 15 and includes a central cap axial opening array of openings 21 (see FIG. 7) to direct a pulse of spray coaxially of the head 15. A plurality of outer opening groups 22 defining an annular array concentrically of and interiorly of the first outlet ports 17 are positioned in an annular array about the axial openings 21. 
     A second conduit impeller housing 23 is in fluid communication with the second conduit 13 within the head 15 to receive the unheated water therethrough and receive the water through an entrance opening 23a and direct the water outwardly thereof through an exit opening 23b. An impeller shaft 25 is rotatably mounted coaxially of the housing 23 and includes a series of stacked impeller blades 24 arranged coextensively and coaxially of the housing 23, wherein fluid from the second conduit 13 directed through the housing 23 effects rotation of the impeller shaft 25 and ultimately a driven gear 27 that projects coaxially and exteriorly through an upper end of the housing 23. Water directed through the impeller housing exit opening 23b is directed therefrom through a central conduit 30 and through a deflector hub 31 that includes a conical support stem that is mounted within a central opening conical outlet seat 32 of the central conduit 30. Water directed therethrough effects rotation of a deflector plate 34 mounted orthogonally to an upper terminal end of the conical support stem 33. The deflector plate 34 is of an eccentrically weighted configuration and includes at least one radial recess 35 directed through a peripheral edge of the deflector plate 34. As illustrated in FIGS. 4, 5, and 6, modified plates 34a and 34b may be utilized utilizing a plurality of radially recesses 35 to determine water to be directed about the deflector plate 34 and in fluid communication with the axial openings 21 to effect pulsing of water therethrough to the axial openings 21 and the outer opening groups 22. The eccentrically weighted deflector plate 34 will selectively baffle water directed to the plurality of outer opening groups 22 through an outer opening group conduit in fluid communication with the central conduit 30, as illustrated in FIG. 3. 
     The output drive gear 26 is in operative communication with a driven gear 27 that is mounted about a rotary hub 28 (see FIG. 3 for example) that in turn includes a rotary hub outer thread 28a that threadedly mounts the central cap housing 20 that includes a central cap inner threads 29. In this manner, rotation of the central cap housing 20, as well as the eccentrically weighted deflector hub 31 effects pulsing of water through the axial openings 21 and the outer opening groups 22. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
