Abstract
Abstract Improved swimming pool apparatus includes contiguous, separate pool and secondary water chambers. The secondary chamber receives pool surface water via a skimmer weir regulated by the main pool water level, and via a pool main drain coupling. A cascaded, submersed filter and pump cleans and returns water to the pool. The apparatus need not be winterized and provides water recirculation and cleaning--even in the presence of surface ice; utilizes pump waste heat for water heating; and assures both pool and pool water cleaning during normal operation.

Total Claims: 8
Claim 1
Independent Claim
131 words
In combination in swimming pool apparatus, a primary swimming pool chamber, a secondary water chamber, skimmer means for passing surface water from said primary swimming pool chamber to said secondary chamber, wherein said skimmer means comprises a first pivotably mounted plate, a second pivotably mounted plate, and further horizontally disposed plate means pivotably connected to said first and second plates, means responsive to the water level in said primary swimming pool chamber for controlling the position of said first plate, drain and conduit means about the lower portion of said primary pool chamber for supplying water from said primary pool chamber to said secondary chamber, and cascaded filter means and pump means submerged in said secondary chamber for returning water passing through said filter means to said primary swimming pool chamber.
Claim 2
Dependent Claim
131 words
