A numberfof small scale porta le I' i `water softeners have been proposed for use in connection with single water faucets in the n `household kitchen or bathroom or laundry 'but these leave much to be desiredin convenience and effectiveness.`

These closable opeiiin threaded holes with screw plugs which may be made of non-corrodible material such as hard rubber, or the material known under the trade name of Bakelite. Advantageously, the closable opening thetop casing 1s at the bot;A 1U l us The j container rect an outilowing stream'of `When the bottom -lat- 00" may take the form; of '95 tom of a funnel-shaped depression formed in the top casing. These openings permit the pouring of sa t solution into the container to pass ,through the zeolite bed.

As stated ante, the bed of water softening material is packed tightly between the screens, which are held y the .container at top and bottom of the bed. This permits u niform distribution of the Water asslng l through the bed and prevents undue e anneling; the capacity of the softener between regwenerations` being thereby materlally 1ncreased. Channeling through aI water softening bed has usually been prevented by leaving a free space above the bed to permit movement andclassifcation of the granules. We have found that in a bed of small dimensions, such as we have in our faucet water softener, the softening action of line anules of Vzeolite 90 1s more effective 'in a tig tly packed bed zeolite' from th locked at top and bottom foraminous elements. t

In assembling' the softener of the present invention the zeolite is introduced through the bottom of the casing and is packed well upon the top screen which is supported by the spider arrangement of the top chamber casing. Then the bottom screen is inserted and the threaded spider is screwed into the container to hold the bottom screen. Finally the bottom closure member is put on and attached to the spider as by means of a lag screw bolt. The softener is then ready for attachment and connection to a water faucet. In most cases the mechanical wear -upon the zeolite in water softening is slight and a bed may last for an indefinitely long time without requiring renewal. However, in the case of a locked bed, suspended matter carried by the water will gradually penetrate into the bed. When a substantial lamount of impurities hasbeen accumulated in this manner it will, to some extent, interfere vwith pro r functioning of the apparatus. This con ition canv be remedied by removing the e container, washing it and it into the container. Such proowever, is cumbersome and, the

Referring to the figures, a container casing 1 of cast metal section encloses a softenin 4chamber 2 containing a packed bed 3- o granular water softening zeoliteor -other granular base eX- change-material. At the top and bottom of this packed bed or body are layers 4 and 5 of zeolite of coarser main body. Above are wire screens 6 and 7 which lite bed and prevent movement thereof. As shown, the top Screen 6 is held against a shoulder 8 formed in the container casing. Above the upper screen 6 is a chamber 9 enclosed in extending from the members 12 to the side walls of the top casing. These members and ribs together with shoulder 8 form a spider serving to hold screen 6 against. upward bulging movement. The lower portion of funnel 11 is provided with a lthreaded opening closed by a gasket 14a and a screw plug '14, which is advantageously made of a non-corrodible compo'- sition such as that known underthe trade name of Bakelite, 'The top chamber l9 is provided with a water outlet 15 which exand of circular crossY tends laterally downward from near the top of casing 10.

The bottom screen 7 is supported by a s ider 16 having ribs 17 and aring 18 threadled into the casing 1. A bottom closure member 19 is held in watertight enga ement 'with the bottom edge of the casing l y lag screw 21 screwed into `spider 16 with an interposed gasket 20 between member 19 and casing 1. A gasket 21a prevents leakage around the screw.

In the side of theclosure member-19 is a threaded opening closed by a gasket 22a and a screw plug 22 made of non-corrodible material. The plugs 14 and 22 are advantabrass inserts 146 and 226 respectively. These inserts, knurled ori the outside and threaded on the inside, are placed in the casting mould and the melted metal is poured around them so that the metal interlocks with the knurling, making the in'- sert and the casting, integral. The bottom yclosure member encloses a chamber 23 and is formed with a lateral extension `24 with an enclosed passage 25 to chamber 23.
