fig . one ( 1 ) shows an environmental view of an industry standard pool skimmer ( 1 ). the pool skimmer ( 1 ) is common within the industry of swimming pools , and differs in generic shapes between the various manufacturers of pool skimmers , based upon the manufacturer &# 39 ; s specific design criteria . the pool skimmer ( 1 ) is shown imbedded in the side of a pool ( 2 ), where the water line ( 4 ) is shown , depicting the water level , which allows the water to flow into the pool skimmer ( 1 ) and hence be drawn into the pump system . the pool skimmer ( 1 ) is comprised of a body ( 6 ), where the body ( 6 ) may be composed of multiple components either solvent welded or glued together . the body ( 6 ) of the pool skimmer has a centrally located hollow portion ( 8 ). the body also has a throat ( 10 ) attached thereon , where the throat ( 10 ) projects outward from the body ( 6 ) and provides a direct conduit from the pool ( 2 ) to the hollow portion ( 8 ) of the pool skimmer ( 1 ). the throat ( 10 ) has a large central through opening or mouth ( 12 ) that allows the water in the pool ( 2 ) and communicates with the hollow portion ( 8 ) of the body ( 6 ). the body ( 6 ) has an upper portion ( 40 ). the pool skimmer ( 1 ) is provided with a lock down lid or cap ( 42 ). the cap ( 42 ) is generally lightly press fit , with a light snap to secure the cap ( 42 ) from easily being dislodged from the upper portion ( 40 ) of the pool skimmer ( 1 ). as can be seen in fig1 , the pool skimmer ( 1 ) comprises an upper portion ( 18 ) and a lower portion ( 20 ). the upper portion ( 18 ) comprises the throat ( 10 ). as is common in the pool skimmer industry , the throat ( 10 ) has a front portion ( 36 ), where the front portion ( 36 ) of the throat ( 10 ) has a weir ( 38 ). the weir ( 38 ) is pivotably mounted to a lower portion ( 40 ) and biased towards the front portion ( 36 ) of the throat ( 10 ). the weir ( 38 ) has positive buoyancy , and prevents debris from migrating from the pool skimmer ( 1 ) back into the pool ( 2 ). the lower portion ( 20 ) of the pool skimmer ( 1 ), has , co - located at the bottom of the pool skimmer ( 1 ), a pool drain inlet ( 14 ) and a pump outlet ( 16 ). the pool drain inlet ( 14 ) and pump outlet ( 16 ) are internally sized to accept pvc ( poly - vinyl chloride ) piping , which is common in the pool and garden industry . an additional feature is to externally size the diameter of the pool drain inlet ( 14 ) and pump outlet ( 16 ) for larger piping , such as 3 . 0 ″ pvc pipes . the reason for using larger diameter piping is that the newer pumps need a larger diameter pipe to provide increased efficiency , due to the higher pump flows generated . as is commonly done in the pool industry , the pipes that are either internally or externally attached would be fusion welded or glued into place . fig1 , 2 , and 3 show that the pool skimmer ( 1 ) is provided with a removable pool skimmer plug ( 22 ). the removable pool skimmer plug ( 22 ) comprises a plug cap ( 32 ) and a plug body ( 28 ). as is common in the industry , the plug body ( 28 ) may be tapered , or may be cylindrically shaped . the plug body ( 28 ) has an upper portion ( 24 ), wherein the upper portion ( 24 ) of the plug body ( 28 ) has a continuous outwardly extended flange or ledge ( 26 ). the ledge ( 26 ) rests upon a correspondingly shaped shoulder ( 44 ) placed towards the lower portion ( 20 ) of the pool skimmer ( 1 ). the plug body ( 28 ) has an internally defined through hole ( 30 ), where the through hole ( 30 ) has means to secure a plug cap ( 32 ). generally the means to secure the plug cap ( 32 ) would be by threadably attaching the plug cap ( 32 ) to the plug body ( 28 ), or by providing a pin and groove system common in many industries , to secure the plug cap ( 32 ) to the plug body ( 28 ). the plug cap ( 32 ) has at least one raised boss ( 34 ). the raised boss ( s ) ( 34 ) provides a grip surface to the plug cap ( 32 ) and allows a user to easily install or remove the plug cap ( 32 ) from the pool removable pool skimmer plug ( 22 ). the plug body ( 28 ) has an outer surface ( 46 ). the outer surface ( 46 ) of the plug body ( 28 ) has a groove ( 48 ) defined therein . the groove ( 48 ) allows an o - ring ( 50 ) to be placed therein . the o - ring ( 50 ) may be adhesively positioned into the groove ( 48 ) preventing dislocation of the o - ring ( 50 ) when the removable pool skimmer plug ( 22 ) is placed into the pool skimmer ( 1 ). as depicted in fig2 , the plug assembly may be provided with a gasket ( 52 ), the gasket ( 52 ) being placed between the ledge ( 26 ) of the plug body ( 28 ) and the shoulder ( 44 ) of the pool skimmer ( 1 ). a second gasket ( 54 ) may be provided and be placed between the ledge ( 26 ) of the plug body ( 28 ) and the cap ( 26 ). as shown in fig3 , the cap ( 26 ) may be adapted to receive at least one poppet valve ( 56 ). the poppet valve will be used to alleviate any vacuum developed during the plug assemblies ( 22 ) use . the external construction of the pool skimmer ( 1 ) is generally defined by the specific company fabricating the pool skimmer ( 1 ). they attempt to provide improved fixity to the gunnite or concrete by creating some form of ribbing that aids in adhesion . this invention does not revise the external ribbing of the original pool skimmer ( 1 ). fig4 shows an alternative construction of the removable pool skimmer plug ( 60 ). the removable pool skimmer plug ( 60 ) has an upper cap portion ( 62 ) where the cap portion ( 62 ) may have an external ledge ( 64 ). the external ledge ( 64 ) would rest upon the shoulder ( 44 ) placed towards the lower portion ( 20 ) of the pool skimmer ( 1 ). the upper cap portion ( 62 ) has a downward protruding boss ( 66 ), where the downward protruding boss ( 66 ) extends into the lower portion ( 20 ) of the pool skimmer ( 1 ) and may have a light friction fit to provide an air tight seal when under vacuum . the downward protruding boss ( 66 ) may have a groove ( 68 ) defined therein , the groove ( 68 ) being adapted to seat an o - ring ( 70 ) between the downward protruding boss ( 66 ) and the lower portion ( 20 ) of the pool skimmer ( 1 ). the downward protruding boss ( 66 ) can be designed with a centrally positioned hollow portion ( 72 ). the upper cap portion ( 62 ) has a grip means ( 74 ), where the grip means ( 74 ) can have a variety of shapes to suit the manufacturer . such shapes may be cruciform , a singular straight bar , a metallic handle or stirrup to be gripped by a users hand , etc . this removable pool skimmer plug ( 60 ) operates as follows . the user places the downward protruding boss ( 64 ) into the lower portion ( 20 ) of the pool skimmer ( 1 ). the downward protruding boss ( 64 ) is sized to provide a light friction fit to the pool skimmer ( 1 ), while the upper cap portion ( 62 ) will rest upon the shoulder ( 44 ) of the pool skimmer ( 1 ). vacuum from the pool pump will draw the removable pool skimmer plug ( 60 ) so that an air tight seal will be formed providing the pump with the maximum available suction to draw water from the main drain of the pool ( 2 ). if no external ledge ( 64 ) is used in the design , upper cap portion ( 62 ) of the removable pool skimmer plug ( 60 ) would have a tapered downward protruding boss ( 66 ) and frictionally fit in the pool skimmer ( 1 ). when the pool pump is in operation , vacuum will draw the removable pool skimmer plug ( 60 ) tighter in the pool skimmer ( 1 ) making a tight seal . at least one o - ring ( 70 ) is used in the removable pool skimmer plug ( 60 ) design . if necessary the downward protruding boss ( 66 ) may have a groove ( 68 ) defined therein for each o - ring ( 70 ). as defined previously , the downward protruding boss ( 66 ) can be designed with a centrally positioned hollow portion ( 72 ). the upper cap portion ( 62 ) has a grip means ( 74 ), where the grip means ( 74 ) can have a variety of shapes to suit the manufacturer . such shapes may be cruciform , a singular straight bar , a metallic handle or stirrup to be gripped by a users hand , etc . although the foregoing includes a description of the best mode contemplated for carrying out the invention , various modifications are contemplated . as various modifications could be made in the constructions herein described and illustrated without departing from the scope of the invention , it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative rather than limiting .
