     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved beer keg tap apparatus embodying the principles and concepts of the present invention and generally designated by the reference numerals 10, 10a, and 10b will be described. 
     More specifically, the beer keg tap apparatus 10 of the instant invention essentially comprises the organization mounted to a beer keg 11, as illustrated in FIG. 1, with the beer keg 11 including a beer keg end wall 12. The end wall 12 includes a cylindrical boss 13 of a type as illustrated in U.S. Pat. No. 4,089,444 incorporated herein by reference. Typically, an annular flange is positioned about the upper distal end of the boss 13. 
     The invention 10 includes a cylindrical housing 14 of a first diameter, including a housing bottom wall 15. The housing 14 is defined about a housing axis 14a (see FIG. 3), with an annular clamping band 16 mounted to a lower distal end of the housing 14 adjacent and in surrounding relationship relative to the bottom wall 15 to include a clamping channel 19 to secure the flange structure of the cylindrical boss 13 of the beer keg. The clamping band includes a first pivot axle 17 and a second pivot axle 18 spaced from the first pivot axle in a parallel relationship, with a clamping band handle 20 extending from the second pivot axle 18 for manual projection of the clamping handle 20 towards the band in the clamping of the band about the cylindrical boss 13. 
     The housing includes a housing upper end 21 including an upper end internally threaded bore 22 of a second diameter less than the first diameter, with an annular abutment step 23 positioned below the internally threaded bore 23 orthogonally oriented relative to the axis 14a. A resilient &#34;O&#34; ring seal 24 is positioned upon the abutment step 23, wherein a housing lid 25 including a lid externally threaded first portion 26 substantially equal to the second diameter is received threadedly in threaded interengagement with the internally threaded bore 22. A lid abutment wall is arranged for engagement with the &#34;O&#34; ring seal 24 to effect a pneumatic and fluid seal relative to the lid and the housing 14. The lid 25 further includes a cylindrical alignment tube 28 fixedly mounted to a bottom surface of the lid for coaxial alignment with the housing axis 14a and in coaxial alignment with a housing cavity 29 directed into the cylindrical housing 14 from the housing upper end 21. A compressed gas canister 30 is coaxially aligned within the housing 14 with its upper end received within the cylindrical alignment tube 28. Upon projection and threaded engagement with the lid 25 into the housing, and more specifically with the upper end internally threaded bore 22, the canister 30 and the canister nozzle 33 is directed onto a conduit spike 34 mounted within a housing cavity conical lower end 31. Upon puncturing of the canister 30, compressed gas therefrom is directed from the canister through the housing upper first conduit 32 that is coaxially aligned with the axis 14a and in pneumatic communication with the gas canister 30 extending from a lower distal end portion of the conical lower end 31. A pressure control rod 35 orthogonally oriented relative to the axis 14a is directed into the housing upper first conduit 32 for selective pressure release of compressed gas from the canister 30 from the housing upper first conduit 32 into a housing lower first conduit 36 in pneumatic communication with the upper first conduit 32. The housing lower first conduit 36 is directed below the housing bottom wall 15 into the beer keg structure. A housing second conduit 37 directed through the bottom wall 15 extends into the housing in pneumatic communication with a housing third conduit 38 that in turn is directed into a flexible dispensing hose 39 that includes a float control nozzle and valve assembly 40 at its outer distal end to selectively permit fluid flow from the beer keg through the flow control nozzle and valve assembly 40. 
     The apparatus 10a, as illustrated in the FIG. 5, further includes a mixing container 41 mounted in fluid communication with the flexible hose 39 and the associated third conduit 38 directed through the flexible hose 39. The mixing container 41 includes a mixing container lid 42 selectively securable to an upper distal end and container overlying the container floor 46. The container lid 42 includes a lid conduit 43 directed therethrough in fluid communication with the flexible hose 39. A lid pressurizing conduit 54 directed and extending into the container 41 from the lid conduit 43 extends positioned in adjacency relative to the container floor 46. A metering aperture 44 directed through the container 41 permits relief of contents such as the mixing fluid 47 within the container 41. The mixing fluid 47 may include various fluid such as an alcoholic beverage to be admixed with the mixture within the keg 11 as desired. 
     The apparatus 10b, as illustrated in the FIG. 7, further includes a lid slide plate 49, including a slide plate opening 52 for receiving a water soluble dye tablet 54 thereon. The slide plate 49 is positioned for sliding and contiguous engagement with a slide plate support flange 51 that in turn is fixedly mounted to the top surface of the lid, with a lid opening 48 arranged for selective coaxially alignment with the slide plate opening 52 upon projection of the slide plate 49 within a slide plate housing 50 that is fixedly mounted to the top surface of the lid 42. Such coloring of beer and the like within the keg 11 is utilized during various holidays, such as St. Patrick&#39;s Day, St. Valentine&#39;s Day, and the like. 
     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.
