Abstract
Abstract An apparatus for chlorinating water of a swimming pool. The device includes a main unit that is inserted into a cannister containing water; the main unit including a perforated barrel with a membrane therearound. The barrel containing salt and a gas collection dome fitted on top of the barrel, having a perforated downward shroud containing anode elements connected by wiring to an exterior electric power source; the anode elements extending into the salt and water, and a gas discharge outlet line extending from the dome.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
231 words
A gas induction swimming pool chlorinator comprising: a substantially cylindrical canister with a hole at the top thereof, said canister made of substantially water impervious material and adapted to hold water which serves as a cathode medium; a main unit adapted to be inserted into the hole of said cylindrical canister, said main unit comprising a center module barrel provided with a plurality of perforations, a cylindrical membrane surrounding said center module barrel, a coil of wire acting as a cathode disposed around said membrane; a slip cap adapted to being disposed on top of the main unit, said slip cap comprising a substantially hemispherical member, a gas discharge line connected to and in communication with the interior of said hemispherical member, a salt charging port in communication with the hemispherical member, a water line attached to and in communication with said hemispherical member, and an electrical conduit in communication with the interior of said hemispherical member; a source of electrical energy; means for connecting said coil of galvanized wire to said source of electrical energy; an electrical wire connected to said source of electrical energy and disposed in the interior of said electrical conduit; a plurality of carbon welding rods connected to said electrical wire; and a shroud made of electrical insulating material having a plurality of perforations, said shroud surrounding said carbon welding rods and acting as an anode.
Claim 2
Dependent Claim
231 words
A gas induction swimming pool chlorinator comprising: a substantially cylindrical canister with a hole at the top thereof, said canister made of substantially water impervious material and adapted to hold water which serves as a cathode medium; a main unit adapted to be inserted into the hole of said cylindrical canister, said main unit comprising a center module barrel provided with a plurality of perforations, a cylindrical membrane surrounding said center module barrel, a coil of wire acting as a cathode disposed around said membrane; a slip cap adapted to being disposed on top of the main unit, said slip cap comprising a substantially hemispherical member, a gas discharge line connected to and in communication with the interior of said hemispherical member, a salt charging port in communication with the hemispherical member, a water line attached to and in communication with said hemispherical member, and an electrical conduit in communication with the interior of said hemispherical member; a source of electrical energy; means for connecting said coil of galvanized wire to said source of electrical energy; an electrical wire connected to said source of electrical energy and disposed in the interior of said electrical conduit; a plurality of carbon welding rods connected to said electrical wire; and a shroud made of electrical insulating material having a plurality of perforations, said shroud surrounding said carbon welding rods and acting as an anode.
