DANIEL LEE, OF SACRAMENTO, AND JOSEPH BELL, OF SAN FRANCISCO,
ASSIGNORS, BY MESNE ASSIGNMENTS, TO THE CALIFORNIA FEED WATER PURIFYING COMPANY, OF SAN FRANCISCO, CALIFORNIA.
FEED-WATER PURlFlEa.
SPECIFICATION' forming part of Letters Patent No. 303,523, dated August 12, 1884.
l Application tiled October Elli, 1883. (No model.)
Be it known, that we, DANIEL LEE, residing in Sacramento, and JosEri-I BELL, residing in the city ol' San Francisco, both in the Stalcof California, and both citizens of the United States, have made and invented certain new' and useful Improvements in Feed-lI/Iatel1 Pnriiier Attachments to Steam-Boilers; and we do hereby declare that the following is a full, clear, and exact description of the same, the accompanying drawings being referred to as a part of this specification.
Our invention relates to an improved means for treating water preparatory to its introduction into boilers for the production of steam; and it has for its object to produce a simple and effective device for the purpose,` and that can be applied to a steam-boiler or generator of any kind, and in whatever situation it may be in use, at very small expense, and Without altering the structure or the location and connection of any of its parts.
Our improvement includes a novel construction of precipitating` and purifying cylinder or tube, and a means for delivering the puri fied water from said cylinder or tube into the boiler-Water in the form of jets, spray, or finely-divided streams, the whole device being adapted to be placed and operated within the water or the steam-space of a boiler, and to be directly connected with the feed-pipe and feedpump, or other source of feed-water supply, all as hereinafter more fully set forth.
The following description fully explains the manner in which we proceed to construct, combine, apply, and use. our improvements,
v the said drawings being referred to by figures and letters, Fi gurc l being a central longitudi-' nal section of the preferred form, and Fig. 2, a similar View of a modification.
A is a tube about twoand one-half inches in diameter, closed at one end by a screw-cap, A', and at the opposite end tted into a coupling, B. Its interior is divided longitudinally into an annular space or chamber, a, and a central cylindrical space, b, by means ofa tube, C, of about one-half its diameter, that is inserted through the coupling-end, and terminates just short ofthe cap end of thesurroundthe tube being open, the outer end takes into a screw-coupling, d, in the end of the part B.
This coupling part (l is a threaded sleeveA adapted to close up the end of the coupling B, and to connect the tube with the end of a feed or supply pipe, E. The coupling B is practically ot' 'the same diameter internally as the main tube, so that a chamber, Z1', is formed around the internal tube C, that is an eXtension of the annular space in the length of tube beyond. From this space bis an outlet, f, anda connection for the end of a blow-off pipe, g. The pipe E is the feed-pipe having connection with lthe usual pump and source of supply for the boiler, and the tubeC is a continuation of this feed-pipe into the precipitating-tube A, the whole length of this latter tube is inserted into the interior of the boiler through an opening cut in the shell, and the Water led in through the feed-pipe, thus sep# arated by the circuitous passage back and forth through the space a b, is brought into a condition or state to be acted upon bythe surrounding temperature and the heated condition ofthe tubesurfaces. This application of heat and the state of quietness induced by the circuitous passage have the effect of producing' separation and precipitation from the water of the solid matter andimpurities held in suspension or contained in the water, in consequence of which the bottom surfaces of thetwo tubes receive the deposit, while the puried water rises or collects at the upper part ofthe space a. From this annular space we take the water for the boiler by discharging it through an outlet or outlets in the upper part ofthe outer tube. XVe do this either by providing several holes, nipples, or orifices along the top portion of the tube,to deliver the feed-water in small streams or jets; or, .as we consider the most effective and desirable mode of delivery, by employing a single outlet, h, and coupling to it by a short upright connection, h', a distributing-tube, H, provided with a number of small outlet-apen turcs, in spaced rows or in clusters,from en d to end along itsr upper surface. This tube is of smaller diameter than the tube A. 'It is placed i in a horizontal position or parallel with the tube below it, and its ends are closed by` caps h2 h2. The use of this distributing-tube enables the length of the precipitating-tube to be reduced, and a compact form of apparatus to be obtained; but, where the structure and situation of a boiler will admit of its insertion, a single introduced, then the construction of au apparatus as in Fig. 2 of the drawings will be of advantage, for the parts are readily inserted in separate pieces and then coupled together from the inside of the boiler.
This device can be readily made and applied by any mechanic of ordinary skill, and at an exceedingly low cost of manufacture and connection as compared with other and more complicated apparatus of the kind, for no special character or style of tube or coupling is necessary, and no' alteration in the structure of the boiler is required'.
In its operation upon water containing mineral matter, as well as mud and sediment, our device is found to remove all vsuch substances and impurities, and to deliver the water in a pure state into the boiler-water. This accumulating matter extracted from the water in its passage through the concentric space is removed at intervals through the blow-otcou nection at the outer end.
Having thus fully described our invention, what we. claim, and desire to secure by Letters Patent, is-
l. In a feed-water supply attachment to steam-boilers, the combination of the precipitating-tube composed of the tubes A C, the coupling B, and the feed and blow-oft' pipes E g, the former connected with the tube C and the latter with the tube A,outside of the tube C, substantially as hereinbefore described.
2. In a feed-watersupply attachment to steam-boilers, a precipitating tube or cylinder adapted for `insertion through the shell of a boiler, and formed of an inner and an outer tube placed concentrically to produce the water spaces a b, of which the inner one is made a continuation or extension of t-he boiler-feed pipe, and the outer one has a discharge-outlet outside of the boiler.
3. A feed-water-purifier attachment consisting of a precipitating tube or cylinder, AC, a feed-pi pe coupled to the said tube C, ablow-oif pipe leading from the annular space between the two tubes, and a delivery outlet or outlets in the upper part of the outer tube, A, substantially as herein described.
4. The combination, with the precipitating tube or cylinder A (l, of the perforated distributing-pipe H, and connectionbetween the said tube or cylinder and the said pipe, substantially as and for the purpose described.
