No. 181 1 North Twenty-seventh street, in-

the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Meanstfor Purilowingis a specifioatlon.

My invention relates to improvements in water purifiers and regulators, and especially 1 to those Where a chemical reagent is added to the water-supply.

The objects of my invention are to, first, automatically secure an adequate supplyof water at all times and yet, second, to maintam this sup ly'in the greatestpossible state to secure these ends.

of purity an efficiency attainable by the a paratus; third, to rovide means, preferab y.

within and 'integra with the apparatus itself, These objects I attain by the devices described and claimed hereinafter and illustrated in the accompanying drawings, in which like characters'of reference refer to'like, parts throughout the respective views.

Figure 1 is an elevation of a feed -water heater and purifier containing myinvention and havin its casing broken away in part to show the filter-bed and the special means for diverting the water which alone and incombination constitute my invention. Fig. 2 is a plan view of a part of the same.

When water purifiers are provided with filters, the latter eventually become clogged or choked with vthe impurities unable to get throu h and which have been caught and re tained by the material or substance of the filter. Especially is this true when. a chemical reagent is used to causea recipitation of the suspended impurities. t then follows that .the supply of water which ultimately passes in the usual way through the clog ed filter is too smallfor the purpose for whic it vis required, and it becomes necessary to sup- It is of course desirable that.

plement' it. this supplement shall be as nearly as possible in the com letely purified condition, and since the o struction arises in the filter,

which is the last step in the process, the supplementary supply should be taken from a ointfver close to, but in front of, the filter.

Thus at t eworst it will be in a fairly urified condition. It is also important that t is supplement shall be automatically supplied according to thedemand.

I prefer to use a horizontal filterandleadthe circulation up through tllQfillJBT-rbdlTOHlbQr low, though I do not limit myself to'that rangement.

This enables .me; tonsccurel a;

sediment chamber beneath the filter bedwhich may be easily washed out. Moreover,

the precipitation fallsaway from rather than onto the filter-bed, making it lesslikely tochoke. My special improvement, however,

lies in the pesuliar form, arrangement, ,con:, jv struction, and location of my increment chamber or by-pass, whichl build insideof v my heater-casing and preferablyintegral'with it, as will be seen on referring. to the drawings.

In l Fig. 1, A is a heater, and B a collecting or filter-tank, preferably but not necessarily placed beneath the heater.

The-o eration of the device is as follows:

The fee entering the heater through 4 is mixed with the chemical reagent entering through 5 and passinginto the trays 10 becomes heated by the steam entering through 1 2. Falling then into the tank, as shown by the dotted arrows, a precipitation of sus ended impurities begins to ta pumps or other means through outlet 16. A

portion of the precipitated sediment is of course carried with the current into contact with the filter-bed and at length partially e place,whic pre cipitation collects on the bottom of the tank.

' the partition 12, passing down through 16,

chokes it so much so as to seriouslyreduce the available supply of water passing through it, and hence available at the outlet 16. As soon as the outflow is reduced materially from the normal the water-level rises in the tank from 22 .when the float-operated valve 6 is wide open, andwhich is the normal waterlevel when the apparatus and filter are working at full capacity, to 21, at which point the feed is being reduced owing to position of float 8. At 21 the water begins to overflow supplementing automatically and as required the amount passing through-the filter 15. Moreover, the deficienc is thus made ood by an increment taken om that part 0 the ap aratus where the most purified water has co lected. Thus the increment,-though unfiltered,has been subjected to all the other steps of the treatment. I v I It is evident that my improvement is not limited in its applicatlon to any. particular kind of water heatin and purifying system,

as the one illustrate nor is it confined to a heater and purifier, either chemical or otherwise, as it might be applicable in a purifier alone and either chemical or otherwise nor do I limit myself to any particular purpose for or process of heating or purifying, nor to the purification of any particular hquid, as water, nor to any special form and arrangement of parts combination. 4

Where in the specification, or the claims I have used the words beyond the filter I' mean a pointon the outlet side of the filter. By normal water-line I mean the water-line established when the system, including the filter, is-normally' operating. By integral ters Patent, is-

1 The combination oi a Waterheater, a

I mean not necessarily homogeneous, but structurally unified.

What I claim, and desire to secure by Letcollecting-tank communicatin therewith; a filter in said tank; an outflow-c amber, and a conduit within the tank, open at the bottom and extending from the lower portion of the tankto above the normalwater-line; a partition in said conduit extending from near 1133' top and forming a passage communicating with the outflow-chamber.

2. The combination of a water-heater, a collecting-tank communicating therewith; a filter in said tank formin an outflow-chamber; a'conduit within sai tank leading from i filter in said tank, and an inclosed passa e in the tank, leading from the lower part 0 the same to the outflow, and vented at the top.

4. The combination of a tank; a filter therein; an outflowchamber beyond the fil-' ter, and an open passage vented at the top, connecting the lower portion of the tank with the outflow-chamber.

5. The combination of a tank; a filter therein, and an open passage within the tank vented at the top and connecting the lower portion of the tank with the outflow. Y i

6. The combination of a tank; a filter therein, and an interior integral conduit vented at the top connectin the lower portion of the tank with the out ow.

7. The combination of a tank a horizontal filter therein; an outflow-chamber beyond the filter, and a passage from the tank below the filter'up to, and vented at the water-line, and communicating with the outflow-chamber.

8. The combination of a tank, a horizontal filter therein, and. a passage in the tank be tween the lower part of the tank below the filter and the outflow, said passage extending to the normal water-line and vented thereat.
