Abstract
Abstract A chlorinator is provided for connection upstream of a pump in a swimming pool water recirculating system which includes a container for holding a supply of chlorinating liquid, a plurality of metering tubes having differing resistances to liquid flow extending into the container with their inlets immersed in the chlorinating liquid, and means for selectively connecting a selected one of the metering tubes to an outlet adapted to be connected to a swimming pool water circulating system. A pressure control valve may be provided between the metering tubes and the outlet and filler means may be provided at the metering tube inlets.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
121 words
In a chlorinator for metering a chlorinating liquid to a swimming pool and having an outlet and a metering system for conducting chlorinating liquid at a metered rate to the outlet, the improvement wherein the metering system comprises a bank of a plurality of independent metering tubes, each having an inlet end for receiving chlorinating liquid and an outlet end, said plurality of metering tubes having restricted liquid passageways of different resistence to liquid flow for metering chlorinating liquid from their inlet to their outlet at differing rates, and selector valve means for selectively connecting the plurality of metering tubes for metering chlorinating liquid to the chlorinator outlet for selectively controlling the metered rate of chlorinating liquid to the swimming pool.
Claim 2
Dependent Claim
121 words
In a chlorinator for metering a chlorinating liquid to a swimming pool and having an outlet and a metering system for conducting chlorinating liquid at a metered rate to the outlet, the improvement wherein the metering system comprises a bank of a plurality of independent metering tubes, each having an inlet end for receiving chlorinating liquid and an outlet end, said plurality of metering tubes having restricted liquid passageways of different resistence to liquid flow for metering chlorinating liquid from their inlet to their outlet at differing rates, and selector valve means for selectively connecting the plurality of metering tubes for metering chlorinating liquid to the chlorinator outlet for selectively controlling the metered rate of chlorinating liquid to the swimming pool.
Claim 3
Dependent Claim
41 words
A chlorinator as defined in claim 1 wherein a valve is disposed between the outlet and the metering tubes, said valve having means for restricting the effective size of the outlet responsive to increases in the velocity of liquid flow therethrough.
Claim 4
Dependent Claim
19 words
A chlorinator as defined in claim 1 or 2 wherein the metering tubes contain threaded rods of differing lengths.
Claim 5
Dependent Claim
18 words
A chlorinator as defined in claim 1 or 2 wherein the metering tubes are tubes of varying length.
Claim 6
Dependent Claim
20 words
A chlorinator as defined in claim 4 wherein the tubes are spirally wound in layers around the same vertical axis.
Claim 7
Dependent Claim
73 words
A chlorinator as defined in claim 2 wherein the valve is a ball valve of the type having a housing forming a chamber with inlet and outlet openings, a ball in the chamber adapted to move toward the outlet opening in response to increase in the velocity of liquid flowing therethrough, said chamber being contoured so that the flow path through the valve is restricted a the ball moves toward the outlet opening.
Claim 8
Dependent Claim
24 words
A chlorinator as defined in claim 6 wherein the flow responsive valve is also a one way valve preventing reverse flow of liquid therethrough.
Claim 9
Dependent Claim
43 words
A chlorinator as defined in claim 3 wherein the metering tubes are mounted within a tubular housing, having an open inlet end, and filter means is mounted at said open inlet end to filter the inlet flow of liquid into the tubular housing.
Claim 10
Dependent Claim
43 words
A chlorinator as defined in claim 4 wherein the metering tubes are mounted within a tubular housing, having an open inlet end, and filter means is mounted at said open inlet end to filter the inlet flow of liquid into the tubular housing.
Claim 11
Dependent Claim
43 words
A chlorinator as defined in claim 1 further comprising a liquid chlorinator container having a top opening, and wherein the selector valve means comprises a mounting head removably mounted in said opening, the metering tubes depending from said mounting head into the container.
Claim 12
Dependent Claim
42 words
A chlorinator as defined in claim 10 wherein a tubular housing depending from the mounting head surrounds the metering tubes and is provided at its lower end with inlet filtering means for filtering the inlet flow of liquid into the tubular housing.
Claim 13
Dependent Claim
49 words
A chlorinator as defined in claim 10 wherein the mounting head has a lower section to which the metering tubes are connected, and a rotatably adjustable cap section having means for connection to a selected one of said metering tubes depending upon the rotated position of the cap section.
Claim 14
Dependent Claim
79 words
A chlorinator as defined in claim 12 wherein the lower section of the mounting head has a plurality of circularly arranged throughbores to which the metering tubes are connected, the wherein outlet is mounted in the cap section of the mounting head, and the cap section is provided with means for connecting a selected one of the throughbores to the outlet depending upon the rotated position of the cap section relative to the lower section of the mounting head.
Claim 15
Dependent Claim
36 words
A chlorinator as defined in claim 13 wherein the cap section of the mounting head is provided with valve means for restricting the effective size of the outlet responsive to the velocity of liquid flow therethrough.
Claim 16
Dependent Claim
17 words
A chlorinator as defined in claim 12 wherein the metering tubes contain threaded rods of differing length.
Claim 17
Dependent Claim
16 words
A chlorinator as defined in claim 14 wherein the metering tubes are tubes of varying length.
Claim 18
Dependent Claim
29 words
A chlorinator as defined in claim 1 wherein the selector valve means comprises an individual shutoff valve for each metering tube for selectively connecting the tube to the outlet.
Claim 19
Dependent Claim
26 words
A chlorinator as defined in claim 1 wherein the selector valve means comprises rotary selector valve means for individually connecting the metering tubes to the outlet.
