Abstract
Abstract A water softening system utilizing a reusable, self-contained water softener device for an agitator type clothes washer. The water softener device includes a quantity of cation exchange resin contained in a torus shaped jacket formed of a closely woven porous, synthetic-fiber fabric. The water softener device is placed in the clothes washer in association with the agitator such that water will be circulated through the resin to effect a hardness reduction thereof by the removal of calcium and/or magnesium ions. After the softening operation, the water softener is removed from the washer and detergent and soiled fabrics are placed therein. The resin is then regenerated by treatment of the device with a salt solution.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
173 words
The method of softening water for a clothes washer having a tub, an agitator, a pump to draw liquid from the tub, and a conduit connected to the pump for selectively returning liquid to the tub comprising the following steps; a. placing a package of cation exchange resin, the package being permeable to water, into the tub and around the agitator, b. introducing water into the tub, c. operating the agitator and pump whereby water will be circulated through the resin by means of said pump and conduit for removing calcium and magnesium ions from the water to effect a reduction of hardness of the water, d. removing the package of cation exchange resin from the tub, e. placing the package of cation exchange resin in a container, f. supplying regenerating solution to the container to immerse the package and at a rate sufficient to effect replacement of calcium ions on the resin by sodium ions, and g. removing the solution carrying evolved calcium ions from the container while maintaining the package immersed.
Claim 2
Independent Claim

Claim 3
Dependent Claim
44 words
The method of softening water for a clothes washer as recited in claim 1, wherein the step of supplying the regenerating solution includes dripping the solution into the container by means of a tank having a plurality of small orifices in the base thereof.
Claim 4
Dependent Claim
37 words
The method of softening water for a clothes washer as recited in claim 1, wherein the step of placing the package of cation exchange resin into the tub follows the step of introducing water into the tub.
