Abstract
Abstract A device for attachment to the bottom drain of swimming pools is described, comprising a cylindrical housing structure seatable and securable over the drain and having a plurality of radially outwardly extending flexible tubes. Operation is effected by directing the inlet flow of pool water in the filtering circulatory system to the bottom drain, whereat it passes under pressure through the housing structure to discharge at the open ends of the tubes with jet action. The resulting whipping about of the tubes at the bottom of the pool serves to maintain dirt particles in suspension for automatic removal by the filtering apparatus instead of settling as dirt and sludge.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A swimming pool cleaner attachment device for use with swimming pools having a forced-flow filter circulatory system including a bottom drain, comprising, in combination, a housing member defining an interior pressure chamber and having a peripheral sidewall, means for attaching said housing member in relatively fixed relation with respect to a swimming pool bottom drain so that the drain is in communication with said housing chamber with said peripheral sidewall above the pool bottom, and a plurality of flexible tubes connected at one end each to a like plurality of openings in said housing member for communication with the interior pressure chamber thereof, whereby when filter circulatory system pool water is fed under pressure to the bottom drain, it will pass through the outer ends of said tubes with jet action imparting random movement thereto at the botTom of the pool.
Claim 2
Dependent Claim
141 words
A swimming pool cleaner attachment device for use with swimming pools having a forced-flow filter circulatory system including a bottom drain, comprising, in combination, a housing member defining an interior pressure chamber and having a peripheral sidewall, means for attaching said housing member in relatively fixed relation with respect to a swimming pool bottom drain so that the drain is in communication with said housing chamber with said peripheral sidewall above the pool bottom, and a plurality of flexible tubes connected at one end each to a like plurality of openings in said housing member for communication with the interior pressure chamber thereof, whereby when filter circulatory system pool water is fed under pressure to the bottom drain, it will pass through the outer ends of said tubes with jet action imparting random movement thereto at the botTom of the pool.
Claim 3
Dependent Claim
46 words
A swimming pool cleaner attachment device as defined in claim 1, including a check valve in said housing member operative to permit the unimpeded flow of pool water therethrough into said housing member for drainage through the pool drain upon reversal of flow under pressure therethrough.
Claim 4
Dependent Claim
59 words
A swimming pool cleaner attachment device as defined in claim 2, wherein said housing member is cylindrical in shape and has an upper end wall, said check valve comprising an opening in said upper end wall defining a circular valve seat and a buoyant ball valve member in said housing chamber and seatable with respect to said valve seat.
Claim 5
Dependent Claim
101 words
A swimming pool cleaner attachment device as defined in claim 1, wherein said housing member is cylindrical in shape and is provided with an upper end wall, said attachment means comprising an internally threaded anchor nut and means for removably and adjustably securing said anchor nut at a central position within the bottom drain with its thread axis extending substantially in the vertical direction, a headed attachment screw, and means including a centrally apertured collar in said housing member through which said attachment screw extends for centrally supporting said attachment screw in depending relation for threaded reception in said anchor nut.
Claim 6
Dependent Claim
100 words
A swimming pool cleaner attachment device as defined in claim 4, including a check valve in said housing member operative to permit the unimpeded flow of pool water therethrough and into said housing member for drainage through the pool drain upon reversal of flow under pressure therethrough, said check valve comprising a central opening in said upper end wall defining a circular valve seat, a buoyant ball valve member in said housing chamber and seatable with respect to said valve seat, said attachment screw being in vertical alignment with said opening to permit access therethrough for turning said attachment screw.
Claim 7
Dependent Claim
59 words
A swimming pool cleaner attachment device as defined in claim 5, wherein said attachment-screw-supporting means comprises a plurality of support rods extending radially outward of said collar, and a like plurality of semicircular seats extending inwardly and being directed upwardly with respect to the peripheral interior of said housing member for removably seating respective end portions of said rods.
