     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved swimming pool skimmer apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the swimming pool skimmer apparatus 10 of the instant invention essentially comprises a swimming pool 11, typically of a generally cylindrical configuration, having a cylindrical side wall 12, with a pump 13 in fluid communication with filter 14, wherein an inlet conduit 15 directed from the swimming pool into the pump 13 directs the water through the pump in the filter 13 and 14 respectively and through a filter outlet conduit 16 to return into the swimming pool, wherein the invention further includes a directional conduit 17 from the filter outlet conduit 16, and the directional conduit 17 intersects respective first and second conduits 18 and 19 directed in opposed orientations relative to one another, as the first and second conduits 18 and 19 typically form a T-shaped intersection with the directional conduit 17. A circumferential hose 20 is directed from the second conduit 19 about the interior surface of the swimming pool side wall 12 to a basket conduit 21, that in turn is mounted to a conduit nozzle 22 of a generally U-shaped configuration. The nozzle 22 is arranged for pivotal mounting relative to the basket conduit 21 for ease of access within the basket upon rotation into spaced orientation of the nozzle 22 from the orientation, as indicated in FIG. 3, to a displaced orientation, as indicated in FIG. 8 for example. A basket member 23 is provided, with the basket member entrance opening 24 positioned in a facing relationship relative to the nozzle 22, wherein the nozzle is in the operative configuration, as indicated in the FIG. 3. The basket member includes basket member mesh side walls 26, each having a float tube 27 directed coextensively therealong, wherein the float tubes 27 are arranged in a parallel coextensive relationship relative to one another for floatatingly positioning the basket member onto the surface of the water within a swimming pool. A support bracket 25 mounted to the basket member extends in a U-shaped end portion for fitting relative to the swimming pool side wall 12. 
     Reference to FIGS. 5 and 6 indicates the use of a valve plate 29 rotatably mounted within the first conduit 18, with a control rod 30 fixedly mounted to the valve plate, with the control rod 30 extending beyond the first conduit 18 terminating in a control rod handle 31 for ease of rotation of the control rod controlling fluid flow through the first conduit 18. Control of the fluid flow through the first conduit is afforded to permit selective circulatory force of the fluid directed from the first conduit in a generally counter-clockwise manner to direct debris into the basket entrance opening 24. 
     The FIG. 8 indicates the use of a flexible mesh insert 32, wherein the insert 32 is arranged for coextensive mounting within the basket member 23 permitting ease of removal of the insert 32. It should be noted that the mesh basket 23 is arranged to receive in an abutting relationship the insert 32 to the basket rear wall 23a providing for confined positioning of the insert within the basket member. 
     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.
