Abstract: A device for use in a swimming pool to prevent a floating chlorine feeder from spending an inordinate amount of time near a single location in a swimming pool due to water currents is disclosed which uses a tether to place the feeder in a central location in the swimming pool. A retainer is attachable to a floating feeder, and a retainer hook is attached to the edge of the pool furthest away from the location to which the feeder is drawn by water currents. A tether cord between the hook and the retainer keeps the feeder in the central location in the pool, where it is maintained by the currents in the pool.

Abstract: A device for use in a swimming pool to continuously dispense chlorine for sanitizing the water is disclosed which has a metering valve designed for precise adjustment of the rate of dispersion of the chemical contained in the feeder. The metering mechanism is made of two segments, with a metering valve cap fitting over a metering valve body to adjust the apertures in the metering mechanism. Precise control is afforded both by a screw-type adjustment of aperture size and by a prevention of inadvertent readjustment of the metering mechanism caused by the device being bumped.
