nitude of the i Referring to .the

Be it known that i, OTTO BEST, a citizen of the United States, residing at San Frailciso, in the eoiinty of San Francisco and State of California, have invented new and useful improve `ents in Feed Devices for Tater-Softener@ of which the following is a specification.

rlhis invention relates to apparatus for softening Water by the addition of chemical reagents, and the object of the present in# ventien is to provide a device for feeding a either in solution, as soda as lime, or both, to a continuously tlowing stream of hard water in the exact proportion necessary, will be very sensitive to variations in magstreani of hard water within a wide range of ynriations. Y

ln the accompanying drawing the ligure is a vertical section, parts being shown in side'elevation, of a softening apparatus 1n which my improved feed device is employed.

chemical reagent drawing, 1 indicates a pipe for supplying hard water, and 2 indicates a tank for containing the chemical reagent for softening the water. The pipe 1 discharges into a water-distributing vessel 3, `from which the waterliows through a bypass pipe 4 into a central section 5 or a softening or reacting chamber 6. The pi e 4f is controlled by a valve 7 by which t e rate of the4 flow of the Water can be varied as desired. The hard water also flows Jfrom the vessel 3 through a pipe 8 dischar ing into a vessel 9, suspended, as shown a 10, from an arm 11 of a balance lever 12, pivoted at 13 on a bracket 14 depending from the bottom of the vessel 3. From another arm 15 of 'thid lever 12 depends aiV the arm 15 so thatweight 16 adjustable on vessel 9, when the it exactly balances the latter is empty, and other arts attached to the arm 11, as will herea er be described. The vessel 9 has a hole 1f? in its bottom th'rough which the water escapes and falls into the central `section 5 of the softening chamber 6. But when water is'in'ther vessel 9, said lvessel is depressed by the'iiveight ofthe water therein. The lower end of the pipe 8 is so arranged that the Water discharges therefrom in a lateral direction 1n 'order to prevent the impact of the water romcausing ythe depression of the vessel 9 and to use only the weight ot the water to cause the depression of said which vessel. A depending ai'm 20, rigidly attached to the balance lever near its fulcruin, hangs verti cally when the vessel is empty, and carries a weight 2l which always tends to restore the balance lever toits normal position in which the arins 11 yand 15 extend horizontally. l

From the outer end of the arm 11 is pivotally suspended a cap 22 into which is screwed the upper end of a pipe or conduit 23,' open at top and bottom, and depending into a vesse 2 tank 2, the pipe 23 passing loosely through a hole 25 in the bottom of said vessel 24. The lower end of said pipe enters loosely the top of a stationary curved pipe 26 eX: tending through a side wall of said tank 2, the upper portion of said pipe 26 being within the tank 2 and the lower portion outside said tank, and discharging into the ccntral section 5 of the softening clian'ib'er. A hood 27 secured around the pipe 23 extends over the open upper end of the pipe 26. A pipe 28 leads from a lower portion o the tank 2 to a pump 29, from which pump a pipe 30 leads upwardly and discharges into the top of the vessel 24, so that the vessel is always maintained full of liquid containin the reagent, part of the excess of the liqui flowing ov r the top edge, of the vessel 24 and returning to the tank 2, of escaping through the hole 25 around the pipe 23. and falling upon the hood l27 and flowing down said hood into thetank- 2. Compressed air is supplied by a .pipe 31,' leading either from an air pump or from a source of supply of compressed air, the latter being here shown at 32, and discharges into the lowest portion ofthe tank 2, the object being to agitato 'the reagent in said tank by means of the'bubbles of air rising therethrough. An orifice 33 is formed in just about the top of the vessel 24, and thereand part there- Specification of Letters Patent. Patented Aug. 20, ll.

4, supported upon the fore above the li uid therein, but when the C arm 11 extends ownwaruly, then the orice 33 in the pipe descends into the vessel 24 and liquid containing the reagent flows from the vessel 241 through said orifice 33 into said pipe` 26 .and then into the section 5 of the softening chamber. The softening reagent may be in solutin in the water orin suspension therein, and it is in order'to in.-

sure that such softening agent is uniformly distributed irthe Water in the tank 2 and vessel 24 that it maintained in circulation hy the pump 29 and is agitated by the air escaping` from the pipe 31.

The pipe el: Vis a ley-pass pipe which is used in case larger quantities of Water are to he softened or nieasured than the standard apparatus provides for. .lli the passage through the pipe 4lis the saine size the passage through the pipe 8, the capacity of feed device for vwaterwould be twice as large, one half of which is measured, the other halt' heii'ig; bypassed direct through the softeningk chamber. iirnyA desired amount can be measured by lay-passing more er less.

The water in which the softening reagent is uniformly distributed, flows downwardly through the central section of the softeniiugv chamber and then upwardly in an annular outer section 34 of said chamber and out by a pipe 35.

A pipe 256 provided with a valve 257 can also be used to draw olia the sludge 'from the sottening chamber when desired.

Supported upon the vessel 24, or in any other suitable manner, is a circular arm Ll0 having thereon two indicating scales 38, 39, the upper 38 indicating the rate of flow of water, and the lower 39 indicating the rate of How olf the reagent, and extending from the arm ll. are upper and, lower pointers el,

42, adapted to inove respectively over said scales to indicate said lioiv.
