(Ci. nth-169) This invention relates to systems and apparatus for filtering a fiuid, and more particularly relates to a system and improved apparatus for filtering and skimming water of a swimming pool and for vacuuming the swimming pool.
It has long been desired to provide a filtering system and apparatus for residential swimming pools which is inexpensive in manufacture, installation and upkeep; economical in operation and maintenance; compact and easily installed either as a portable or permanent installation, and reliable, practical, simple, ellective, durable and efficient in operation.
In heretofore known conventional type filtering systems and apparatus for residential type swimming pools it is generally required that the apparatus of the filtering system be permanently installed and in most instances much of the apparatus is underground, somewhat elaborate and complicated which results in an installation that i expensive to manufacture and install since these installations normally require that manholes be dug, underwater drains provided, valves, gauges, steel tanks and the like, be employed to assure the proper operation thereof.
Also, in the known, more conventional type of filtering systems and apparatus it is necessary that some type of filtering additive or powder the used; require that tedious back washing and messy flushing operations be employed, and large water losses and pressure problems occur which make the operation, maintenance and upkeep of such installations complicated, unreliable and expensive.
Also, the known conventional types of filtering systems usually employ apparatus which is rather complex from the operational standpoint and which includes somewhat complicated and elaborate plumbing installations that normally require that the residence owner or pool user be subjected to an educational program in order to be able to understand and operate the filtering system and the apparatus which is employed therein.
It is the primary object of thi invention to provide a filtering system and apparatus for residential swimming pools which is economical'to manufacture; inexpensive to install, maintain, and operate; compact and easily installed either as a portable or permanent installation, and is simple, durable, reliable, practical, effective and efi icient in operation.

In operation, the filtering-system 10, when employed to skim and filter the water 12 ofthe swimming pool 14-, the pump device will effectively force or'induce the water 12 to flow through a skimming zone at the skimmer unit 22 whereat undesirable particles will be skimmed from the water 12 at the water level is, with the water 12 then flowing through a filtering zone at the filter unit 24 whereat' the impurities contained in the water 12 will beremoved therefrom and thereafter the skimmed and filtered water 12 will be returned to the swimming pool 14 through the conduit 34, pump device 39 and the conduit 36.
When it is desired to filter andlvacuum the swimming pool 14 without requiring that any substantial part of the water 12 be removed therefrom or without requiringrthat the water level 16. be substantially lowered, the filtervacuum device 26 is separated from the skimmer unit 22 and employed to remove particles fromthe swimming pool 14 with a part of the water 1'2 being employed as a conveying agent, through theinfiuence of the pump device 39, to convey the particles from the vacuuming zone at the V vacuum unit 28 into the filtering zone at the filter unit 24 whereat the particles and the impurities beingjcarried by the water 12 are removed with the water 12 then passing through. the conduit 34, the pump device 38 and the corn duit 36 back to the swimming pool 14.
Attention is now directed to FIGS. 2, 3 and 4 of the drawing wherein there is illustrated, in more detail, the skimmer-filter-vacuum apparatus 18. It is to be noted a that the skimmer unit 22 of the apparatus 12; includes a housing. 38* substantially of rectangularconfiguration and definedby atop portion ii), a bottom portion 42, side portions 44-44, a' front portion 46 and a back portion 48.
In the preferred embodiment of the skimmer-filtervacuum apparatus 18, the bottom portion 42, the front portion 46 and the back portion 48 of the housing $8 are formed from a single integral sheet of material, such as anticorrosive metal, plastic, or the like, that is bent into substantiallyf a J-shape with the front portion 46 being the shorter leg ofthe J. and; terminating in an edge portion S0. The side portions 4444 are also formed from like material which may be any suitable anticorrosiye metal,
. plastic, or the like and are reinforced and joined to the back portion 4,'the bottom portion 42 and the 'front portion as of the housing Eli-by stiitner strips 52 which are curved laterally to. define rounded corners 54 with the residence,;at a water level 16 with'the filtering system It) 1 also being operable to vacuum the swimming pool 14 without requiring that any substantial amount of the waters -12 be removed so that-the water levelld maybe mains tained duringthe vacuuming operation at the desired level. a
The filtering'system It} includes a skimmerfilter-,vacu-.
-um'apparatus 18 having a skimmer-filter device Ztiwhich j is provided with a skimmer unit 22 anda filter unit '24 that is sep arably supported within the skimmer unit t which defines a skimming edge'p ortionfover which the" water llZflows through the opening fill int'o'the confines of strips 52 extending along the front of the housing ES and terminating inside edges 56-56; which arespaced apart and which define with the edge portion 50 and an-edge 58 of the top portion '49 an opening 69 in the frontportion'd of the housing 3%. H 1
A floating liquid gate structure 62 is disposed in the opening till ofthe front portiontd. of 'the housing 33 and the gate structure '62 is termed from suitable flexible material, such as any anticorrosive metal, plastic, or the like; which enables the gate structure e2'to' be 'movably mounted, as illustrated .by phantom. lines in FIG: 3 of the 7 drawing, within the opening dd-sothat the gate structure ".ez is self adjusting to varying water levels 16 and floats in the water 12 with an upper edge portion 66 thereof being'in spaced relationshipto the edge 58 in "a' manner the housing '33 with theiskimmer'edgetportion 66 automatically effecting a high velocity current flow on the surface of the water 12 during the skimming operation. Any suitable wedge or locking mechanism 64, such as the bolt-nut structure, as illustrated, may be employed to secure the gate structure 62 to the housing 38. Since the gate structure 62 is bodily flexible and floatably movably mounted to the housing 38 with the skimmer edge portion 66 being self adjusting to varying water levels 16 the skimmer unit 22 is eflective to skim only in a skimmer zone which is near the water level 16 where undesirable matter is normally present and hangs suspended in the water 12 and there is no waste of effort or any decrease in the efficiency of the skimming operation since the skimmer unit 22 does not affect the deeper water levels where the water 12 will normally be free and clear of such undesirable matter.
The floating liquid gate structure 62 is provided with a plurality of sealed compartments 68 which impart sulficient buoyancy to the gate structure 52 to enable the gate structure to be effectively buoyantly floatably supported in the water 12 at the water level 16 thereof, and if necessary the sealed compartments 63 of the gate structure 62 may be increased or decreased in capacity to vary the buoyant effect thereof in accordance with the requirements of the system.
In the preferred embodiment of the invention, as illustrated in FIGS. 2 and 3 of the drawing, there is provided adjustable support structure 7% which removably or releaseably secures the housing 38 to a side wall or apron 72 of the swimming pool 14 so that the floating liquid gate structure 62 will be positioned relative to the water level 16 as described above.
However, it may be desirable that the skimmer-filtervacuum apparatus 13 be floated at the water level 16 in the water 12 of the swimming pool 14 in order to increase the effective skimming operation of the skimmer unit 22 of the apparatus 18. In order to float the apparatus 18 it is only necessary that the apparatus 18 be removed and separated from the wall or apron 72 of the swimming pool 1 and in this embodiment or modification of the invention, not illustrated, an additional fioat structure is employed in place of the support structure which effectively floats the skimmer-filter-vacuum apparatus 18 in the water I2 with the sealed compartments 68 of the gate structure 62 being effective to dispose the skimmer edge portion 66 adjacent to the water level 16.
The top portion 40 of the housing 38 is provided with an opening 74 into which there is disposed the filter-vac uum device 26 with the filter-vacuum device 26 being separably and removably supported therein and resting on brackets 76 which are secured to the back portion 48 and side portions 4444 of the housing 38. It is to be expressly noted that the filter-vacuum device 26 is separably and removably nested within the confines of the housing 38 and by reason of the brackets '76 the filtervacuum device may be easily removed from within the housing 38 for reasons to be more fully described and disclosed hereinafter.
The filter-vacuum device 26 comprises the filter unit 24 and the vacuum unit 28 which are secured together by suitable structure '78, such as screws, bolts or the like. The filter unit 24 includes a shell 80 formed from any suitable material such as a non-corrosive metal or plastic material with the shell 8t) being of sachel-like configuration, i.e., an inverted U shape in transverse section as illustrated in FIGS. 3 and of the drawing, defined by a top portion 82 having depending therefrom end 84 and side 86 wall portions with the side wall portions 86 being disposed in a manner which converge toward the top portion d2 so that the side wall portions 86 are inclined away from each other as they extend from the top portion 32. The end 84 and side 86 wall portions of the shell 86 terminate in an annular enlarged end portion 88 to define an open end 9%) for the shell 80. The end portion 88 is provided with a plurality of spaced apart internally threaded recesses 92, for a purpose to be more fully disclosed and described hereinafter. inwardly projecting, elongated supporting-spacer ribs 94 are disposed along the inner surface of the side wall portions 86 of the shell 80. The top portion 82 of the shell 8% is provided with a neck portion 96 which defines an opening 98 through the top portion 82 of the shell 8& and to which the first conduit 34 may be connected so that the skimmed and filtered water 12 may pass through the opening 98 and then flow through the first conduit 34 to the intake side of the pump device 3%) during the filtering-skimming-vacuuming operation of the system 10.
A ,filter medium support me which is of substantially the same configuration as the shell is received within the confines thereof and supported in spaced relationship thereto by reason of the ribs 94. The filter medium support 100 includes a top portion 102, end wall portions 104 and side wall portions 106 which depend from the top portion 102 with the side wall portions 106 diverging relative to each other. In the preferred embodiment of the invention the top portion 102 and the side wall portions 1% of the filter medium support 100 are constructed from suitable mesh screen such as a non-corrosive metal or plastic cloth while the end Wall portions 104 thereof are solid. Since the filter support 190 is supported in engagement with the ribs 94 which project inwardly from the shell 80 there is defined between the filter medium support 1% and the shell 86 a space through which the water 12 passes in its travel from the swimming pool 14 to the first conduit 34.
If desired or necessary other additional filter medium supporting structures of suitable mesh screen may be employed, if necessary, and it is to be understood that the size of the mesh screen may vary according to the requirements or needs of a particular installation or system in which the skimmer-filter-vacuum apparatus 18 is employed. It is believed that the disclosure and description of a single filter medium support 1% will suffice for the purpose of describing and disclosing the features there of in this invention.
A sheet of filter medium 119, preferably of paper, having a substantially rectangular configuration, is placed in direct contact with the inner surface of the filter medium support 1th and extends entirely over the full area of the filter medium support 1% which is defined by the mesh screen top portion 102 and the mesh screen side wall portion 1% thereof.
In order for the filter medium 119 to be removably retained within the confines of the shell 80 in spaced relationship relative thereto by reason of the ribs 94, with the filter medium lit) covering the mesh. screen top 1&2 and side Wall 1% portions of the filter medium support 1%, a resilient cage-like member 112, as illustrated in FIG. 6 of the drawing, is provided, which is disposed on the inner side of the filter medium 110 and constantly exerts a pressure force thereagainst to retain the filter medium 116 positioned against the filter medium support 1%.
The resilient cage-like member 112 which may be formed of any suitable anticorrosive metal, or plastic material, or the like, and includes a plurality of spaced apart inverted U-shaped members 114 each having a bite portion lid which extends into depending leg portions II8I13 that are disposed in diverging relationship relative to each other and terminate in end portions 129. Longitudinally extending elongated substantially straight members 122 are connected to the adjacent end portions 12% of the leg portions 318 and a longitudinally extending elongated substantially traight member 124- connects the adjacent bite portions 116 of the U-shaped member 114 together.
It should be noted that the members 122 together with the leg portions 118 and bite I16 portions form a continuous bearing-supporting surface which engages the filter medium 1.1% along the peripheral edge portion If desired additional Ushaped members 114 may be pro-- vidcd for exerting a bearing-supporting surface for intermediate areas of the filtcr'medium Elli. The leg portions 118 correspond substantially in configuration to the inverted U-shape of the shell 8% and the filter medium support Mitt but in actual practicethe leg portions 113 normally diverge to a greater degree than the shell 3%; and the filter medium support 1% in order to create the pressure force, as indicated by the arrows in FIG. 3 of the drawing, which enables the filter media lit to be retained within the confines or" the shell 8i) during the operational step of filtering the water 12 either alone or in combination with the operational steps of vacuuming and skimming the water 12.
In the operational position, the members 122 of the filter support Hill rest against an abutment 123 which protects inwardly from adjacent the enlarged end portion 88 of the shell 8% with the filter medium Hi and filter medium support 1% also being interposed between the members 122 and the inner surface of the shell a'ilto assure that there will be no relative movement therebetween during the operation of the filtering unit 24.
In order that the filter medium 116 may be easily and quickly removed and replaced between the cage-like member 112 and the filter medium support 1% there is provided a handle which in the preferred embodiment ofrthe invention is in the form of an L-shaped projection 126 on each of the members 124 which extend generally inwardly toward each other and then outwardly away from the bite portions 116 of the cage-like member 112 and terminate beyond the confines thereof whereat the projections 12612 6 are easily accessible to an operators fingers so that the projections 126 may be readily grasped and urged toward each other in a manner which will cause the leg portions 118 and the members 122 to removed from within the confines of the shell 81) since the size of the bite portion 116 of the cage-like member 112 is smaller than the open end 99 of the shell 80.-
With the cage-like member 11.2 removed, as described and disclosed above, the used paper filter medium 114) 'may then be removed and replaced.
The vacuum unit 28 of the filter-vacuum device includes a scrubbing-block or head 136 having an endless annular flange portion 132 which defines an opening 134 therethrough of a size substantially equal to the open end of the shell 86 and larger in area than the area of the bite portion 116 of the cage-like member 112 so that the cage-like member 112 may be passed there-,
through The flange portion 132, of the block 13% is of greater width than the enlarged end portion 88 of the shell 8% and is ofis'et upwardly and extends generally inwardly therefrom relative to the inner surface of the secure the-head 136 of the vacuum unit728 to the'shell 80 of the'filter unit 24.
that is away from the opening 913 in the neck'portionfio of the shell 80.
. 8 able structure 142, such as an internally threaded opening-therein or therlilze, for receiving an elongated rod-like actuator 1441, as shown by phantom lines in FIG, 5 of the drawing, which enables the filter-vacuum device '25, on removal thereof from the housing 38 of the skimmer unit 22, to be actuated in a desired manner along the bottom or side walls of the swimming pool 14 With the bristles 138 in contact therewith to remove and vacuum undesirable particles therefromu lnrtne vacuuming operation, a part of the water 12 V in the swimming pool 14- will be employed as the conmove inwardly toward each other free of the abutment 128, as shown by phantom lines in FIG. 3 of the drawing, which'enables the entire cage-like support 100 to be The vacuum unit '28 further includes abracket 14-5 7 which is secured'to 'gillfi exterior or outer surface {of the I shell 86in close proximity and adjacent to the neck por ltion fio'thereon. The bracket l ltl is provided with -suit veying agent for moving the undesirable particles from the swimming pool ld into the filtering zone at the filter unit 24 and then through the opening 134, the opening 98, the first conduit 34, the pump device 30, the second conduit 36 and then returned to the swimming pool 14 so taat it is not-necessary to remove the water 12 from the swimming pool 14- which enables the swimming pool 14 to be vacuumed while being maintained in a substantially water-filled condition. 7
