Abstract
Abstract A pool skimmer and the like including a skimmer assembly adapted for use with residential and commercial installations with means for selectively operatively connecting various lines and apparatus in a system for liquid surface skimming, vacuuming and liquid draining having means for cleaning and filtering pool liquid for reuse thereof, wherein means are provided for simplifying establishing all necessary conduit connections for main outlet plumbing, skimmer plumbing and vacuum connections, the assembly including selectively usable and operable control and vacuum plate and float stopper to establish desired operating conditions.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
110 words
A pool skimmer and the like comprising: A. a skimmer body; B. a surface liquid weir operably opening into said skimmer body; C. a removable strainer basket positioned in said body below said wire; D. a pump outlet port in said body adjacent said basket; E. a skimmer inlet port in said body above said basket; F. a control and vacuum plate rotatably supported above said inlet port and having an opening therethrough; F1. a trimmer valve shoe depending from said plate; G. means for selectively closing said plate opening; and said valve shoe, upon rotation of said plate, selectively partially or completely opening or closing said skimmer inlet port.
Claim 2
Dependent Claim
110 words
A pool skimmer and the like comprising: A. a skimmer body; B. a surface liquid weir operably opening into said skimmer body; C. a removable strainer basket positioned in said body below said wire; D. a pump outlet port in said body adjacent said basket; E. a skimmer inlet port in said body above said basket; F. a control and vacuum plate rotatably supported above said inlet port and having an opening therethrough; F1. a trimmer valve shoe depending from said plate; G. means for selectively closing said plate opening; and said valve shoe, upon rotation of said plate, selectively partially or completely opening or closing said skimmer inlet port.
Claim 3
Dependent Claim
95 words
A pool skimmer as claimed in claim 1, and including seal means between said plate and said body for sealing off an upper portion of said body into which said weir opens from a lower portion of said body, in conjunction with closure of said plate opening by the closure means therefor, and wherein upon rotation of said plate to open said skimmer inlet all liquid flow will be drawn through said skimmer inlet when brushing a pool, or lowering pool water level or draining a pool, with all water passing through said strainer basket.
Claim 4
Dependent Claim
110 words
A pool skimmer as claimed in claim 1, said plate opening closure means comprising a buoyant float stopper floatingly attached to said plate and operable during normal pool operation to permit flow of surface waters traveling over said weir to flow through said plate opening, through said strainer basket and through said pump outlet port, and further being so operable when water level in a pool drops below an effective skimming level whereby water level in said body lowers drastically, that said float stopper is drawn into said plate opening, thereby creating a sealed circuit from said skimmer inlet port through said strainer basket and through said pump outlet port.
Claim 5
Dependent Claim
50 words
A pool skimmer as claimed in claim 3, said plate opening being tapered, and said buoyant float stopper being of a corresponding configuration and size, facilitating positive sealing engagement with said opening and being operable upon lowering of water level in said body to automatically seat in said tapered opening.
Claim 6
Dependent Claim
37 words
A pool skimmer as claimed in claim 4 and further including a float stopper holder in said plate in which said float stopper may be securely wedged during pool vacuuming operations or when otherwise not in use.
Claim 7
Dependent Claim
48 words
A pool skimmer as claimed in claim 2, and further including a retaining ring in said body for coaction with said plate to lock said plate in position, while permitting rotation thereof, and serving to prevent plate dislodgment by air bubbles or plate buoyancy during inoperable pump conditions.
Claim 8
Dependent Claim
49 words
A pool skimmer as claimed in claim 1, said plate opening being adapted for establishing a vacuum hose Connection therethrough, and with said trimmer valve shoe closing said skimmer inlet port creating a direct circuit from said plate opening through said strainer basket and through said pump outlet port.
Claim 9
Dependent Claim
68 words
A pool skimmer as claimed in claim 1, said body having an equalizer inlet in the lower end thereof, a spring loaded equalizer valve in said equalizer inlet, a flow balance slide valve in said body slidably juxtaposed over said pump suction outlet, said flow balance slide valve being operable to meter and control flow from a plurality of skimmers to establish a balanced flow from each skimmer.
Claim 10
Dependent Claim
30 words
A pool skimmer as claimed in claim 8, said flow balance slide valve being operable to regulate flow through said skimmer in conjunction with controlled flow through said skimmer inlet.
Claim 11
Dependent Claim
29 words
A pool skimmer as claimed in claim 1 wherein said control and vacuum plate is constructed of optically clear material for permitting visual inspection therethrough of said strainer basket.
Claim 12
Dependent Claim
34 words
A pool skimmer as claimed in claim 1, said control and vacuum plate and said body having coactable indicia thereon to visually indicate different operating positions of said plate and said trimmer valve shoe.
