Abstract
Abstract The disclosure relates to a swimming pool drain chamber which is positioned over an outlet of a swimming pool. The chamber includes sealing means for effecting a liquid seal adjacent the outlet. An upper portion of the chamber extends above the normal water surface of the swimming pool. The water in a line connected to the outlet can be removed without lowering the water level in the entire pool to an elevation below the outlet. In a preferred embodiment, the chamber extends below the outlet to facilitate draining the line completely and also to keep small amounts of water entering the chamber out of this line.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
235 words
Swimming pool apparatus for use on a pool filled with water up to a predetermined maximum level and having a side outlet positioned below the normal surface of the water in the pool, such outlet normally being filled with water, comprising, in combination, chamber means including a rectangular watertight box having an opening in one side for positioning in alignment with a pool outlet, sealing means for effecting a liquid seal between said chamber means and the pool adjacent the pool outlet, said sealing means including a gasket mounted on said watertight box adjacent such side opening, said sealing means preventing the pool water from entering said chamber means and the pool outlet, said chamber means including an upper portion which extends above the predetermined maximum water surface level when said chamber means is sealed to the pool, said upper portion defining an opening located above the predetermined maximum water surface level, said chamber means further including a lower portion which extends below the pool outlet when said watertight means is sealed to the pool whereby, when said chamber means is sealed to the pool with said sealing means and is drained to below the pool outlet, the pool outlet is drained without lowering the normal water surface level, and suction cup means mounted on opposed sides of said watertight box for removably mounting said watertight box in a surrounding relationship with the pool outlet.

Claim 3
Dependent Claim
144 words
Swimming pool apparatus for use on a pool filled with water up to a predetermined maximum level and having a side outlet positioned below the normal surface of the water in the pool, such outlet normally being filled with water, comprising, in combination, chamber means including a front panel, two opposing side panels attached to said front panel and a bottom panel attached to said front and side panels, said chamber means defining an interior chamber, an open top for positioning above the predetermined maximum water surface level of the pool and an open side opposite said front panel, gasket means mounted adjacent such open side for sealing such interior chamber to the pool, and suction cup means mounted on said side panels adjacent such open side for attaching said apparatus to said pool with said open side in alignment with the pool outlet.
Claim 4
Dependent Claim
144 words
Swimming pool apparatus for use on a pool filled with water up to a predetermined maximum level and having a side outlet positioned below the normal surface of the water in the pool, such outlet normally being filled with water, comprising, in combination, chamber means including a front panel, two opposing side panels attached to said front panel and a bottom panel attached to said front and side panels, said chamber means defining an interior chamber, an open top for positioning above the predetermined maximum water surface level of the pool and an open side opposite said front panel, gasket means mounted adjacent such open side for sealing such interior chamber to the pool, and suction cup means mounted on said side panels adjacent such open side for attaching said apparatus to said pool with said open side in alignment with the pool outlet.
Claim 5
Dependent Claim
24 words
Swimming pool apparatus, according to claim 2, including a reinforcing member extending between the upper edges of said side panels, adjacent such open side.
Claim 6
Dependent Claim
201 words
Apparatus for use in a swimming pool filled with water up to a predetermined maximum level and having a side outlet positioned below the normal surface of the water in the pool, such outlet normally being filled with water, comprising a first tubular conduit defining a chamber, said conduit having an open end and a closed end, a second tubular conduit having two ends and an internal opening extending therethrough, means connecting one end of said second conduit to said first conduit at a point intermediate said open and closed ends with said second conduit spaced from said open end by a distance greater than the distance from the pool outlet to the predetermined maximum water level, said first tubular conduit defining a storage reservoir below the lowest portion of said second tubular conduit, said opening in said second conduit communicating with said chamber in said first conduit and means for sealing the other end of said second conduit to the pool outlet with said open end of said first conduit located above the predetermined maximum water level whereby, when said chamber is emptied by water, said pool outlet is drained and any excess water is stored in said storage reservoir.
Claim 7
Dependent Claim
201 words
Apparatus for use in a swimming pool filled with water up to a predetermined maximum level and having a side outlet positioned below the normal surface of the water in the pool, such outlet normally being filled with water, comprising a first tubular conduit defining a chamber, said conduit having an open end and a closed end, a second tubular conduit having two ends and an internal opening extending therethrough, means connecting one end of said second conduit to said first conduit at a point intermediate said open and closed ends with said second conduit spaced from said open end by a distance greater than the distance from the pool outlet to the predetermined maximum water level, said first tubular conduit defining a storage reservoir below the lowest portion of said second tubular conduit, said opening in said second conduit communicating with said chamber in said first conduit and means for sealing the other end of said second conduit to the pool outlet with said open end of said first conduit located above the predetermined maximum water level whereby, when said chamber is emptied by water, said pool outlet is drained and any excess water is stored in said storage reservoir.
Claim 8
Dependent Claim
37 words
The apparatus of claim 4, wherein said means for sealing other end of said second conduit to the pool outlet includes thread means on said other end of said second conduit for threadably engaging the pool outlet.
