Abstract
Abstract The automatic apparatus for chlorinating a swimming pool utilizes a timing device for actuating a solenoid valve to enable chlorine, which is supplied by gravity from a chlorine tank, to enter the circulating line at a point either before or after the circulating pump which directs fluid from the pool to the filter tank. In a preferred embodiment, the chlorine enters the circulating line at the output side of the filter tank. A check valve may be substituted for the solenoid valve in which case a chlorine pressure pump is installed between the chlorine tank and the check valve.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
Swimming pool chlorinating apparatus, comprising: means for filtering the water in a swimming pool, means connecting said means for filtering with said swimming pool for circulating water to and from said means for filtering, means for injecting chlorine into said means for circulating, first valve means between said means for injecting chlorine and said means for circulating, means for opening and closing said first valve means to inject a desired amount of chlorine solution into said means for circulating, additional valve means and means for storing a cleaning agent, said additional valve means is positioned between said means for injecting and said first valve means and has a first position wherein chlorine solution is injected into said means for circulating and a second position wherein said cleaning agent is passed through said first valve means to remove obstructions therein, and said means for injecting chlorine mounted above the level of water in said pool for injecting chlorine solution by gravity feed into said means for circulating.
Claim 2
Dependent Claim
166 words
Swimming pool chlorinating apparatus, comprising: means for filtering the water in a swimming pool, means connecting said means for filtering with said swimming pool for circulating water to and from said means for filtering, means for injecting chlorine into said means for circulating, first valve means between said means for injecting chlorine and said means for circulating, means for opening and closing said first valve means to inject a desired amount of chlorine solution into said means for circulating, additional valve means and means for storing a cleaning agent, said additional valve means is positioned between said means for injecting and said first valve means and has a first position wherein chlorine solution is injected into said means for circulating and a second position wherein said cleaning agent is passed through said first valve means to remove obstructions therein, and said means for injecting chlorine mounted above the level of water in said pool for injecting chlorine solution by gravity feed into said means for circulating.
Claim 3
Dependent Claim
49 words
Apparatus as in claim 1 wherein said chlorine solution is injected in said means for circulating at a point upstream from the inlet of said means for circulating water into said swimming pool whereby the injection of chlorine is aided by the suction created by said means for circulating.
Claim 4
Dependent Claim
33 words
Apparatus as in claim 1 wherein said means for injecting chlorine includes a transparent line to said first valve means whereby the condition of the line and said first valve means is observed.
Claim 5
Dependent Claim
24 words
Apparatus as in claim 1 wherein said first valve means is a solenoid valve and said means for opening and closing is a timer.
Claim 6
Dependent Claim
29 words
Apparatus as in claim 1 wherein said means for injecting chlorine includes means for injecting water therein and means for maintaining the chlorine solution therein at a desired level.
