FEED-WATER PURIFIER.

SPECIFICATION forming part of Letters Patent No. 754,907, dated March 15, 1904.

Application led June 29, 1903.

To all whom, t may concern.'

Be it known that I, JAMES M. SMITH, a citi- Zen of the United States, residing at Sharon,

in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Feed-Water Purifiers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Whichv -it appertains to make and use the same. f

This invention relates to improvements in boiler and feed water purifiers.

The object of the invention is to provide simple and eifective feed-water conductor in which provision is made for separating the scale-forming impurities from the water and discharging the same upon the exterior.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as Will be hereinafter more fully described, and particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure 1 is a fragmentary horizontal section through the device and shell of a boiler, and Fig. 2 is a vertical longitudinal section through the separator.

Referring now more particularly to the drawings, the numeral l represents a boiler shell or casing, and 2 a feed-water-supply pipe. The pipe 2 is connected with the outer end of a conducting-pipe 3, and a regulatingvalve 4 is disposed at the point of junction of these pipes to enable the feed of water to the boiler to be controlled. The pipe 3 extends longitudinally from one end to near the opposite end of the boiler and is connected by a union or coupling 6 with an oppositely-extending pipe 7 forming practically a continuation of pipe 3. At its end opposite the coupling 6 the pipe? is connected by a coupling 8 with the inner end of a separator 9, dis- Serial No. 163,5 94. (No model.)

. riahand its apertures or meshes form ports or passages connecting the said two chambers 12 and 13. The coupling or inlet pipe 8 enters the inlet end of the chamber 12,l and a discharge-pipe 14C is in communication with the opposite or outlet end of said chamber 12. The chamber 13 is in communication with the inlet 8 only through the chamber 12, but is rprovided with a discharge-pipe 15, having a controlling-valve 16. This discharge-pipe 15 :is designed for the blowing out of the sedi- I ment fromthe chamber 13 to the exterior of the boiler, the valve 16 being opened at intervals to discharge accumulated sediment.

In operation the water flows from the pipe 2 through thepipe 3 and thence through the pipes 7 and 8 into the chamber 12 of the separator 9. In its passage through the pipes 3 and 7 the Water absorbs enough heat from the surrounding water and steam to raise its temperature to that of the water in the boiler. As this temperature is much above 2120, the sediment and scale-forming constituents in the water separate in the chamber 12 and while Howing through said chamber settle into the chamber 13 through the screen-diaphragm 11 and under the pressure accumulating from the conversion of a portion of the water into steam are blown out through the pipe 15 when valve 16 is opened. The purilied water liows from the chamber 12 through the dischargepipeint'o the boiler' 1, as will be readily understood.

In the present instance I have shown the separator disposed inside the boiler; but it may be disposed outside the boiler', if desired, or occasion necessitates such disposition.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention. l

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

IOO

1. A feed-water purier, comprisinga casing adapted to be horizontally disposed, a longitudinal horizontal perforated diaphragm separating the interior of Said casing to form superposed separating and sediment chambers, said chambers being in communication only through the perforations of said diaphragm, water inlet and discharge connections at the ends of the upper or separating chamber, and a sediment-discharge at the end of the sediment-chamber below the said waterdischarge, substantially as described.

2. A feed-water purilier, comprising a casing adapted to be horizontally disposed, a longitudinal horizontal perforated diaphragm separating the interior of said casing to form' superposed separating and sediment chambers, said chambers being in communication only through the perforations of said diaphragm, water inlet and discharge connections at the ends of the upper or separating chamber, and a Valved blow-off pipe entering the end of the sediment-chamberbelow the Water-discharge connection and extending some distance into said chamber, substantially as described.

3. A feed-water purifier comprising a casing adapted to be horizontally disposed, a longitudinal horizontal perforated diaphragm separating the interior of said casing to form superposed separating and sediment chambers, said chambers being in communication only through the perforations of said diaphragm, caps closing the ends of said chamber, water inlet and discharge connections upon said caps at the ends of the upper or separating chamber, and a Valved blow-off pipe entering the outlet end of the sedimentchamber through the cap carrying the Waterdischarge connection, substantially as described.

4. In a feed-water heater and puriiier, the combination of a water-supply pipe, reverselyextending conducting-pipes connected thereto, and pipes extending back and forth in parallel relation, and a separator disposed parallel with the pipes and comprising a casing, a longitudinal horizontal perforated diaphragm separating the interior of said casing to form superposed separating and sediment chambers, said chambers being in communication only through the perforations of said diaphragm, a water-inlet connection between said conducting-pipes and one end of the separating-chamber, a water-discharge connection at the opposite end of said chamber, and a sediment-discharge at the end of the sedimentchamber below the said water-discharge, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
