UNITED STATES GEORGE T. MUNDAY, OF BRENHAM, TEXAS.
FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent N 0. 566,602, dated August 25, 1896.
Application filed March 4, 1896.
To all whom 722% may concern:
Be it known that I, GEORGE T. MUNDAY, of Brenham, in the county of W'ashington and State of Texas, have invented new and useful Improvements in Feecl-lVater Heaters, of which the following is a full, clear, and exact description. 7
This invention relates to feed-water heaters for steam-boilers, and the objectis to pro vide such a heater having an arrangement of distributing-troughs located in such a manner as to evenly distribute the water over tubes in thin streams or a thin sheet, whereby it may be quickly heated, and, further, in so constructing the parts that the interior portions comprising the circulating tubes and troughs may be easily removed for the purpose of cleaning.
I will describe a heater embodying my invention and then point out the novel features Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a transverse section of the device substantially on the line 1 1 of Fig. 2. Fig. 2 is a longitudinal section. Fig. 3 is a portion of one of the supporting-frames. Fig. 4 shows the tube-supporting bracket, and Fig. 5 is a detail showing the means of attaching the extension-tracks.
Referring to the drawings, A designates the shell of the heater, of suitable boileriron and having a removable head A. To the interior of the shell, and on opposite sides thereof, are bolted angle-irons a, which extend the entire length of the shell and form tracks for supporting the tubes, and providing means for removing the same, as will be hereinafter more clearly described. l'Vithin the shell is arranged a frame for supporting a series of tubes B. This frame comprises end pieces consisting of vertical bars B and transverse connecting-rods b, and the two end frames are connected together by four longitudinal rods 6, which are threaded at their ends and provided with nuts engaging against the opposite sides of the end frames, whereby a rigid structure is obtained. From the end of the frame brackets 11 extend upward and provide bearings for transverse shafts biupon Serial No. 581,825. (No model.)
the ends of which rollers b are mounted and designed to engage with the tracks a.
The vertical portions 13 of the end frames are provided with vertically-elongated slots Z1 and to the ends of the tubes B are secured brackets B having at their upper ends outwardly-extended hook portions 1), adapted to pass through the slot-openings 12 in the frame portions B. It will be seen that the slots 19 are of sufficient length to allow the hook portions to pass through them, and then by lowering the tubes the hook portions will engage the outer sides of the frame portions B. The several tubes B are open at the ends, so that there may be a free circulation of the steam through them. Extended longitudinally and above each of the upper tubes B is a trough B and the several troughs B are secured together by means of bolts or otherwise, and they are supported by the end frames in a similar manner to that of the tubes. The edges of these tubes B are preferably serrated, as shown at If, which will cause the breaking up and fine distribution of the water flowin g from the troughs. The several troughs B are connected with transverse equalizing-troughs (Z.
G indicates the steam-inlet pipes extended through the upper portion of the shell A, and 0 indicates the water-feed pipes leading through the upper portion of said shell and extended downward toward the troughs B Secured to the pipe G just above the troughs B are transverse troughs c, which receive water from the pipe G through the perforations in the lower portion of said pipes.
The lower portion of the shell A is provided with an outlet blow-off pipe 0, and below the series of tubes and supported by the movable frame is a screen C consisting of wire-cloth and designed to catch scale as it falls from the several tubes, thus preventing the same from reaching to the bottom of the shell to interfere with the free circulation of the water.
lVhen it is desired to remove the series of tubes and troughs from the shell, I may eniploy extension-tracks C? of a suitable length and having means to engage the ends of the tracks a when the head A is removed, and the outer ends of these track-extensions C may be supported in any desired manner. I have here shown the extension-tracks as provided with hook portions 0 designed to engage in eyes formed in the ends of the tracks within the shell.' In operation the live steam will circulate freely through the tubes,so as to heat the water as near the temperature corresponding to the boiler-pressure as possible and effect the rapid formation of scale upon the outer surfaces of the tubes.
lVhen it is desired to remove the tubes and troughs for the purpose of cleaning and also the screen 0 for the purpose of removing the scale gathered thereon, thehead A of the shell A may be removed by first removing the fastening-bolts and then, after attaching the extension-tracks C the whole interior mechanism may be readily drawn out.
Having thus described my invention, I claim as new and desire to obtain by Letters Patent 1. A feed-waterheater, comprising a shell, tracks arranged longitudinally therein, a frame comprising vertical end pieces within the shell having rollers engaging the said track, a series of tubes supported by said frame and removable therewith, troughs supported by the frame above the tubes and extended parallel therewith and also removable with the frame, steam-inlet pipes, water-inlet pipes leading through the upper portion of the shell, and transverse troughs supported by the lower ends of the said water-pipes above the firstnamed troughs, substantially as specified.
2. A feed-water heater, comprising a shell having a removable head, tracks arranged longitudinally in said shell, a frame comprising vertical end pieces having rollers engaging the said tracks, circulating-tubes open at the ends and having removable engagement with the vertical end pieces of said frame and removable therewith, longitudinally-extended troughs supported by the frame above the tubes and removable therewith, steaminlet pipes,,water-inlet pipes, and transverse troughs for receiving water from the waterpipes and discharging the same into the longitudinal troughs, substantially as specified.
A feed-water heater, comprising a shell. a frame comprising vertical end pieces removably supported therein, circulating-tubes removable with the frame removably connected to the end pieces, and distributingtroug-hs supported by the frame above the tubes and having serrated edges, substantially as specified.
i. A feed-water heater, comprising a shell, a frame removably mounted therein and comprising vertical end pieces provided with slotopenings, a series of tubes open at the ends and having hook-shaped brackets to engage in the said slots, steam-inlet pipes, waterinlet pipes, and transverse troughs for receivin g water from said water-pipes, substantially as specified.
5. In a feed-water heater, a shell, a carriage comprising end pieces remo ably mounted therein,a series of circulating-tubes supported by vertical end pieces of said carriage, aseries of distributing-troughs supported by said carriage above the tubes and communicating one with another, and means for feeding steam and water to the interior of the shell, substantially as specified.
0. In a feed-water heater, a shell having a removable head, tracks secured horizontally in said shell and having eyes formed in the ends near the removable head extensiontracks having hooks for engagement with the tracks within the shell, and a tube-support ing frame movable on said tracks, substantially as specified.
