     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved mixer apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the mixer apparatus 10 of the instant invention essentially comprises a container 11, having a continuous side wall 12 surrounding a container cavity 13. A rigid first shaft 14 is diametrically directed through the container side wall 12, having respective first and second mixing blades 15 and 16 mounted in a spaced relationship relative to the first shaft 14 and projecting on diametrically opposed sides of the first shaft in a parallel relationship relative to the first shaft 14, as indicated in FIG. 2 for example. The first shaft 14 is arranged to include a first shaft first end 17 having right hand thread, with a first shaft second end 18 having left hand thread, with the respective right and left hand thread portions of the first and second ends 17 and 18 respectively directed into respective first and second coupling sleeves 21 and 22 respectively. The first and second coupling sleeves 21 and 22 are arranged to include a spline interconnection relative to a second end third shaft 19 and 20 that are coaxially aligned relative to the first shaft 14 and extend from the respective first and second ends 17 and 18 to the first shaft in rotative mounting relative to the container side wall 12. A second shaft right hand thread 23 extends from the side wall 12 into the container cavity 13 along the second shaft 19, with a third shaft left hand thread 24 extending from the side wall 12 into the container cavity 11 to thereby direct fluid that may be present within the container cavity 13 during a mixing procedure preventing such fluid from being directed through the container wall and the bearing mount of the second and third shafts 19 and 20 within the container side wall 12. Further as indicated, the first shaft right hand thread is indicated by the numeral 25, with the first shaft left hand thread indicated by the numeral 26 in the FIGS. 2 and 4 for example. 
     The FIGS. 5 and 6 indicates the use of third and fourth blades 27 and 28 slidably mounted relative to the first and second blades 15 and 16, with the first and second blades including first and second slots 32 and 33 having respective first and second fasteners 30 and 31 to secure the third and fourth blades in an adjustable relationship relative to the first and second blades. 
     The FIG. 7 further includes seventh and eighth blades 37 and 38 respectively, having seventh and eighth pivot axles 41 and 42 mounting the seventh and eighth plates pivotally relative to the second blade 16, with fifth and sixth blades 35 and 36 having fifth and sixth blade pivot axles 39 and 40 pivotally mounting the respective fifth and sixth blades 35 and 36 to the first blade 15 in addition to the third blade structure 27. 
     The additional blade structure enhances the mixing and agitation of components within the container cavity 13 for optional employment. It should be noted that the fifth through eighth blades are freely pivotally mounted in an unfixed relationship to permit the blades to adjust within the cavity 13 during a mixing procedure. 
     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.
