Abstract
Abstract A long thin flexible teflon tube extending in a drain line of a reservoir from the point where the line opens into the bottom of the reservoir to a point outside the reservoir where the tube extends outside the drain line and is removably connected to a chlorine gas bottle, there being provided at the point where the tube is connected to the bottle a fixed metering port, and there being provided a protector tube surrounding the thin tube from the drain line to the chlorine bottle, and a gas diffuser connected to the end of said thin tube where it opens into the reservoir. A method of installing the above mentioned apparatus wherein one end of the thin tube is placed into the drain line at the bottom of the reservoir, and then, by drawing water from the reservoir through the drain line, the tube is drawn through the drain line to a point outside the reservoir, and then the tube is passed through a hole in the side of said line at a point outside the reservoir, then the tube is connected to a chlorine gas bottle.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
123 words
In an apparatus particularly adapted to chlorinate continuously swimming pool water in a swimming pool having a drain pipe which opens into the pool throUgh an inlet port: a source of chlorine gas having an outlet port; a long thin flexible plastic tube having a first and a second end; mounting means on said first end for connecting said first end to said outlet port; a metering port at said first end for metering gas entering said tubing from said outlet port, said metering port having an orifice passage of diameter substantially smaller than the inside diameter of said tubing; and means at said second end of said tubing for preventing said second end from entering the inlet port of the drain pipe
Claim 2
Dependent Claim
123 words

Claim 3
Dependent Claim
27 words
The invention set forth in claim 1 including: diffuser means connected to said second end of said tube for diffusing gas exiting said tubing into minute bubbles.
Claim 4
Dependent Claim
39 words
The invention set forth in claim 2 wherein said diffuser means includes: a housing having a cavity therein with a discharge opening substantially larger than the tube; and a porous plate sealed to said housing across said discharge opening.
Claim 5
Dependent Claim
46 words
The invention set forth in claim 2 wherein: the diffuser means is attached to be used at the inlet of a drain pipe in the bottom of the pool, and said diffuser means includes: retainer means for preventing said diffuser means from entering said drain pipe.
Claim 6
Dependent Claim
118 words
In combination with a reservoir pool having a drain pipe which communicates the bottom of the pool with a pump, said drain pipe having means forming an upwardly facing inlet port located at a deep portion of the pool, a system for continuously chlorinating water in said pool, said system comprising: a source of chlorine gas having an outlet port; a long thin flexible tube having a first end connected to said chlorine gas source and a second end, said tube extending through said drain pipe with said second end opening at the inlet port forming means of said drain pipe so that gases emitting from the tube will not be emitted into water within the drain pipe.
Claim 7
Dependent Claim
118 words
In combination with a reservoir pool having a drain pipe which communicates the bottom of the pool with a pump, said drain pipe having means forming an upwardly facing inlet port located at a deep portion of the pool, a system for continuously chlorinating water in said pool, said system comprising: a source of chlorine gas having an outlet port; a long thin flexible tube having a first end connected to said chlorine gas source and a second end, said tube extending through said drain pipe with said second end opening at the inlet port forming means of said drain pipe so that gases emitting from the tube will not be emitted into water within the drain pipe.
Claim 8
Dependent Claim
46 words
The invention set forth in claim 5 including: a grate across the inlet port of said drain pipe; and diffuser means connected to the second end of said tubing for diffusing gas exiting said tubing into minute bubbles, said diffuser means being anchored to said grate.
Claim 9
Dependent Claim
134 words
The invention set forth in claim 5 wherein: said chlorine gas source is located adjacent said drain pipe and has an outlet port; said flexible tube extends from said source outlet port through a hole in the wall of said drain pipe into said drain pipe; and there is provided tube shielding means enclosing said flexible tube from said drain pipe at said hole to said source outlet port, said tube shielding means comprising: a protector tube of relatively hard material as compared to said flexible tube; connector means connecting a first end of said protector tube to said outlet port of said source; mounting means at a second end of said protector tube, said mounting means providing a seal between the wall of said drain pipe around said hole and said protector tubing.
Claim 10
Dependent Claim
69 words
The invention set forth in claim 7 wherein said metering port is formed by a rod with minute passage therethrough said connector means comprises: a bushing having a central hole therethrough; means sealing said bushing to said outlet port; means connecting said protector tube to said bushing; means sealing said rod in said hole in said bushing; and means sealing said flexible tube to said hole in said bushing.
Claim 11
Dependent Claim
65 words
The invention set forth in claim 7 wherein said mounting means comprises: anchor means for securing said mounting means to said drain pipe at said hole in said drain pipe wall; a sleeve having a central bore receiving said second end of said protector tube at least partway through said bore; and means on said sleeve for adjustably connecting said protector tube to said sleeve.
Claim 12
Dependent Claim
26 words
The invention set forth in claim 7 including: means at the second end of said protector tube for sealing said flexible Tubing to said protector tube.
Claim 13
Dependent Claim
171 words
In a system for continuously chlorinating water in a pool, which pool has a pipe which extends from a first point outside of the pool to a second point in the structure of the pool below the normal water line of the pool, said pipe having means forming a port at said second point opening into said pool: a source of chlorine gas near said first point; a long thin flexible tube having a first end and a second end, said tube extending through said pipe from said first point to said port, said first end of said tube being connected to said gas source whereby gas may be supplied into the tube; exit means at the second end of said tube forming an outlet to permit gas within the tube to exit the tube, said exit means being positioned at least partially out of said pipe into said pool so that bubbles exiting the tube will exit into the water in the pool and not the water in the pipe.
Claim 14
Dependent Claim
171 words
In a system for continuously chlorinating water in a pool, which pool has a pipe which extends from a first point outside of the pool to a second point in the structure of the pool below the normal water line of the pool, said pipe having means forming a port at said second point opening into said pool: a source of chlorine gas near said first point; a long thin flexible tube having a first end and a second end, said tube extending through said pipe from said first point to said port, said first end of said tube being connected to said gas source whereby gas may be supplied into the tube; exit means at the second end of said tube forming an outlet to permit gas within the tube to exit the tube, said exit means being positioned at least partially out of said pipe into said pool so that bubbles exiting the tube will exit into the water in the pool and not the water in the pipe.
