\VILLIAM J. AUSTIN, OF FOND DU LAO, WISCONSIN.
FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent No. 487,549, dated December 6, 1892.
Application filed December 11 1891. Renewed November 10, 1892. Serial No.451,506. (No model.)
.To all whom it may concern.-
Be it known that 1, WILLIAM J. AUSTIN, a citizen of theUnited States, residing at Fond du Lac, in the county of Fond du Lac, State of Wisconsin, have invented certain new and useful Improvements in Feed-Water Heaters, of which the following is a specification, reference being had therein to the accompany ing drawings.
My invention relates to feed-water heaters steam-injected; and its object is to provide improved means for heating feed-water, purifying it, and extracting any oil that may be therein. I attain these objects by the construction illustrated in the accompanying drawings, in which- Figure 1 is a side view, partly in section, of the feed-Water heater constructed in accordance with my invention. Fig. 2 is a horizontal section of the same on line m as of Fig. 1, but showing only one-half of the deflector and a portion of the perforations in the lilterer. Fig. 3 is a horizontal section of one of the manhole-plates and a portion of the shell to which it is attached. Fig. 4. is a front view of one of the manhole frames and plates.
In the drawings, A represents the cylindrical shell of the device, which is supported vertically on legs A and has centrally in the bottom thereof a vertical pipe A that extends a short distance above said bottom into a chamber B, that I call the oil chamber or separator. This pipe A is for the admission of the exhaust-steam from an engineinto the device. Said steam is projected against the under side of the disk 0, that is supported on top of vertical bolts 0, secured to the bottom of the shell. Said disk has its edge turned down to deflect the current of steam. To conduct said exhaust-steam to nearly the top of the shell, there is a central vertical pipe D, made in sections, each one transversely closed at the top, the lower section of which is attached to the horizontal partition B constituting the top of the oil-chamber B and the bottom of the water-holding chamber E. Said chamber has an inverted conical top E to direct the Water falling from above toward a central annular passage e, formed between the tubular inner wall E of the water-chamber and the lower section of the steam-pipe D.
Above the chamber E is a series of waterchambers F F F. The upper chamber has centrally on its top a pipeffor the escape of any steam that may not have been condensed in the water-chambers. It also has a pipe f entering one side thereof to bring ina supply of cold Water into the apparatus. The inner end of said pipe has perforations in its side, and after passing through the side of a downwardly-flanged deflector G, resting upon the top section of the pipe D, terminates under said deflector. The bottom of each chamber F and F consists of a perforated plate f upon which are placed a few thicknesses of burlap-cloth f and above the latter a suitable amount of excelsior, hay, or any suitable material, on top of which is placed a perforated plate f said parts constituting a filterer H.
To cause the ascending steam to be evenly distributed in the chambers F F downwardly-flanged deflecting-plates G are mounted upon each section of the pipe D in the middle of said chamber, and said sections of pipe are provided in their sides with perforations 61 for the issue of steam under the deflectors and its re-entrance in the section of the pipe above the deflector. The waterholding chamber E has a short distance above its bottom 13 a similarly-constructed filterer H but coke is the material preferably used therein, the water passing upward therethrough when there is a sufficient amount in the central passage 6.
In the bottom of the water-holding chamber E, but above its filter, there is a pipe K, through which the hot water is drawn from the apparatus, and said pipe has a perforated rose on its inner end. Said apparatus is provided with a glass water-gage L to indicate the height of the water in the chamberE, and in the bottom of the latter there is a blow-off pipe L Passing through the side of the chamber E, adjacent to the top thereof, there is an overflow-pipe M, that is provided with a downwardly-looped pipe M forming a trap when fullor nearly full of water, and thus preventing any escape or leakage of the exhaust steam and operating automatically without the use of any valve.
In the bottom of the oil-chamber B there is a pipe I) to lead away into a suitable reservoir or vessel any oil that may have collected therein.
Each of the water-chambers F F E is provided with an opening in the side to permit the removal and renewal of the filtering material. Said openingis surrounded by a manhole-framep, which is closed by a manholeplate P. To secure the latter the frame 2) is provided with two lugs 19 on each side, and to said lugs eyebolts p are pivoted. The outer end of two of said bolts pass through lugs P of the plate P and retain it permanently hinged to the frame, while two similar eyebolts pass through slotted lugs P, from which they can be swung when it is desired to remove the plate P. Stud-bolts q are also used to connect the plate P with the frame.
Having now fully described my invention, I claim- 1. A feed-water heater consisting of a vertical cylindrical shell, a vertical steam-receiving pipe in the bottom thereof, a series of water-chambers and of superposed pipes D,and steam-deflecting plates closing their upper ends, said pipes having lateral opening under and above said deflecting-plates, with a waterholding chamber encircling the lower pipe of said series and having an annular passage between it and said chamber, substantially as described.
2. In a feed-water heater, the combination of a series of water-heating chambers, each one having filterers therein, and a series of superposed steam-pipes passing therethrough and provided with lateral openings above and under deflectors therein, with a waterholding chamber having a water-passage centrally and under the same with the overflowpipe M, having a downwardly-looped trap M substantially as described.
In testimony whereof I aflix my signature in presence of two witnesses.
