LIQUID TREATING DEVICE Filed April 25, 1929 Patented Aug. 26, 1930 PATENT OFFICE ELMER HASLETT, OF SAUSAI ITO, CALIFORNIA LIQUID -TREATING DEVICE Application filed April 2a, 1929. Serial No. 357317.
This invention relates to devices for, treating liquids such as water for example, to change its characteristics or composition, or purify it. f
An object of the invention is to improve and simplify devices for treating liquids. Another object of the invention is to provide an improved device for treating liquids which will be easily portable, easily and quickly attachable to or detachable from faucets or other liquid outlet connections, which will be convenient for use in connection with kitchen sinks, wash bowls, bath and laundry tubs, and washing machines; which will always have continued maximum effectiveness in use, and which will be relatively simple and inexpensive.
Other objects will appear from the follow ing description of an embodiment ofthe invention, and the novel features will be artioularly pointed out in the appended cla1ms.'
In the accompanying drawing: Figure 1 is a side elevation of a device constructed in accordance with the invention and showing the manner of its use;
Figure 2 is a sectional. elevation of one end of the same; I
Figure 3 is a sectional elevation of the other end of the same; 3o Figure 4 is a sectional elevation of the connection as adopted for use with non-threaded liquid outlets or faucets, and
Figure 5 is an elevation of a member connected between the device and the plumbing outlet to enable regeneration of the treating substance.
In the illustrated embodiment of the invention, a plurality of stretches'of conduit or hose 1, such as rubber hose, of any suitable and convenient length or diameter are coupled together end to end, and each is pro-' vided, at one end, with a suitable connector 2, by which it may be connected to a faucet 3 or other source of a liquid to be treated. Where water is to be softened the faucet 3 may be the usual faucet or outlet of a domestic water supply. The other end of each stretch of conduit or hose may have connected there- .50 to a discharge device or nozzle 4, which may couple the stretch to the connector 2 of another stretch of hose.
The connector 2 (Fig. 2) may have a nipple portion provided with internal threads extending from its open end for threaded engagement with the usual threads at the discharge ends of some faucets.
The rear end wall of the connector is provided with a tubular projection 5 which is received within the passage 6 of the conduit or hose 1, and secured against withdrawal by a suitable clamping device 7 which surrounds the portion of the conduit or hose that receives the projection 5 and clamps the hose thereto.
A screen 8 and reticulated plate 9 are disposed face to face and secured within the connector 2 against an internal shoulder or abutment 10 of the connector, by means of a ring 11 threaded into the open end of the-- connector.
The inner periphery of the ring may have lugs 12 by which the ring may be threaded into or out of the connector thru the use of a suitable spanner wrench or. other tool. The usual compressible annular gasket 12 may. be placed against the ring 11.
The discharge or nozzle device 4 (Fig. 3) may comprise a short length of cylindrical tubingsecured within the hose or conduit by a clamping device 13, similar to clamping device 7. Both of these clamping devices may comprise a flange on the tubing with fingers 14 which are clinched over the hose.
A screen 15 and reticulated plate 16 are clamped against an internal flange or abutment 17 of the tube 4, by a split ring 18 which is sprung into a groove 18 in the inner end of the tube. The abutment or flange 17 may be provided in the tube 4 in any suitable man- 90 nor, and the exterior of the outer end ofthe tube 4 may be threaded for connection.
The screens 8 and 15 are preferably disposed against the inner faces of the reticulated plates 9 and 16 respectively, that is,
facing one another thru the passage of the hose or conduit.
The space in the passage of the conduit or hose 1, between the screens 8 and 15 is filled with a quantity of small solid particles or no granules 19 of the substance intended for treating the liquid, and these particles or granules are confined in the conduit or hose b the screens 8 and 15. The screens permit is e passage of liquid thru the hose or conduit, and the liquid, while so passing, will move in contactwith the sai'd'particles or granules and be modified thereby. When water bearing any minerals in solution are to be treated in a manner to soften them, the particles or granules 19 may be of any natural'or synthetic zeolite. I
When the mineral bearing water passes over the zeolite particles or granules, there occurs what is called in the art a base exchange during which the minerals, such as calcium and magnesium which are thevmost common minerals found in water, are removed from the water. The zeolite substance may be regenerated in the usual. manner b passing a salt solution thru the hose and a owing the salt solution to remain in contact with the zeolite a few minutes.
A liquid in passing thru a mass of small solid particles or granules tends to form channels thru the mass and then the liquid will flow thru the channels and not fully contact with the solid substance, such as zeolites.
- In such a case the liquid is not fully treated and various ineffectual or impractical attempts have heretofore been made to overcome this trouble.
This trouble has now been overcome by this improvement. Since the massbf granules or particles is confined loosely in the flexible ose or conduit, the flexing of the hose or conduit'in use, agitates the mass automatically so as to break up any channels in the mass which may start to form, thus eliminating the necesslty of special mechanical agitators. Instead of a device formed of a series of connected units or stretches each complete, a
single len h may be emp oyed but the series of couple units serves to prevent packing of the material.
When one desires to connect this device to a liquid outlet or faucet having no threads upon its discharge end, the ring 11 of Fig. 2 is replaced b a longer but similar ring 20 (Fig. 4), an a hollow frusto-conical insert 21 of resilient material such as elastic rubber, is disposed within the cavity of the connector, with its eripheral flange resting upon the outer end face of the rm 20, and secured thereagainst by another ring 22, s1m1lar to ring 11, of Fig. 2.
This connector is then fitted to thefaucet outlet, and the discharge end of the faucet will enter the insert 21 which stretches to -receive and closely fit it, and make a water tight-connection thereto. A chain 23 connected to the connector 2 by pins 24 may be hooked over the faucet to secure the connector thereon, and is adjustably connected toone pin to enable its length to be varied.
To facilitate regeneration of the zeolite, a casing 25 may be provided with a removable cover 26, which carries a nipple 27 similar to cennector 2 to enable connection of the casing to a faucet. The other end of the casing has a screened outlet nipple 28, externally threaded for coupling to a connector'2, which previously was connected to a faucet, so that water or liquid must pass thru the casing 25 before reaching the flexible hose sections. The casing may be filled with salt and water run slowly thru the casing to cause regeneration of the zeolite for ten or fifteen minutes. The casing may then be removed from the hose until regeneration is again needed. The casing may be recharged with salt by means of the removable cover 26.
A device such as illustrated and described is particularly useful as a water softener, when filled with a zeolite for example, and may be detachably connected to the usual faucets at kitchen sinks, laundry tubs, bath tubs, wash bowls, etc., in homes or hotels. The attachment or disconnection of such a device is a simple act and easily and quickly performed by anyone, even a child. A device of this type is not only simple and compact, but relatively inexpensive and very effective.
It will be understood that various changes in the details and materials herein described and illustrated may be made within the principle and scope of the invention as expressed in the ap ended claims.
