FEED-WA-TER HEATER.
SPECIFICATION forming part of Letters Patent No. 347,228, alated August l0, 1886.
LApplication tiled-May 11T, 1886. Serial No. 202,441. (No model.)
To-@ZZ whom it 1mm concern:
Be it known that we, THOMAS CLARKE and W'ILLIAM S. FLYNN, citizens of the United States, residing at Jersey Cit-y. in the county of Hudson and State of New`Jersey, have invented certain new and useful'Improvements in Feed-fatel- Heaters; and we do declare the following to be a full, clear, and exact description of the inventionl such as will enable others skilled in the art to which it appertains to make and use the same, reference being had t0 the accompanying drawings, and to thelet ters and figures of reference marked thereon, which form a part of this specification.
This invention relates to devices for heating feed-water by the utilization of exhaust-steam or other media possessing caloric which would' otherwise be spent to no purpose. y
It consists in the novel features more p articularly referred to hereinafter, and claimed and shown in the annexed drawings, in which- Figurel is a sectional view on the line Y Y of Fig. 2, the middle portion being broken away. Fig. 2 is a sectionalview on thelines X X of Figs. l and 3, the middle portion being likewise broken away. Fig. 3 is an end view showing the relative positions andoutlines of the inclosed parts by dotted lines.
For the sake of illustration, the device is shown having its middle portion broken away; and it consists of a case, A, having an inlet and exit at opposite ends, a series of tubes, each bent in return-folds, and castings forming a common `iunction for the opposite ends of the'series. The case may be of any desired' length and any shape, in cross-section, the rectangular form shown being preferred, as it permits the tubes B to be arranged in a series, the one above the other, Vwithout any excessive space intervening between the inner walls and the tubes which would allow the heating media to escape before it could part with its caloric. The ports A 'A2 are formed at opposite ends of the case, the one through one end or head, the other through a side near the opposite end, preferably the under side. flhe one is used as the inlet, the other as the exit. The heating medium, which may be 5o;eXhaust-steam, waste products'of combustion, hot air, Ste., in its passage is compelled to traverse the entire length of the case and come length. ,branches extending from the castings.
in contact with the tubes, which, by reason of the .extended surface, causes it to part with nearly all of its caloric, which is transferred to and raises the temperature of the water passing` through the series of tubes. The tubes B are each bent in a series of -returir folds, I), the ends of which terminate on the same side to enter the rear sides of hollow cast- 5: ings C, located at the end ofthe ease opposite to the port A. The front ofthe castings are provided with single openings d, which registcr with corresponding openings, u. in the head or end of the case. Pipes D, screwed into the openings a and d, which are threaded, hold the castings in place and form the ingress and egress of the feed-water. The bore Of the tubes is'very small, and they are arranged so that a space surrounds each 7o tube on every side throughout their entire They form, as it were, numerous The rear sides of the castings have a series of tubular projections c castVv therewith, into which the ends of the tubes are inserted and secured by brazing, swaging, or other means where by a tight joint is formed. By reason of the series of return folds formed in the tubes an extended surface lis presented, and the con- 8O traction and expansion of the tubes will be taken up by the bends or folds, thus relieving the joints from any undue strain. Tater entering by one of the pipes D is separated by one of the castings into a number of small streams corresponding with the number of tubes through which itiows, and is again reunited by the other casting, and makes its exit by a solid stream by way of the other pipe, D'. During its passage the water is/go heated, and may be used for feed-water or other desired purpose.
We are aware that a feedwater heater for locomotives has been devised, consisting of a case having within a manifold provided with 9 5 an inlet, a series of tubes leading from said manifold and terminating in a return-bend, a second like series leading from the returnbend and parallel with the irst series, said second series terminating in a second bend, a roo third series of tubes leading from said second bend and terminating in a third bend and terminating in a second manifold having an exit, said series of tubes alternately extending in opposite directions, und each tube being Substantially parallel with the other.
Having illus described our invention, what we claim, und desire to seein-e by Letters lutent, iis- The herein shown und described feed-water heater, comprising the following,` elements in combination: the euse provided with un inlet und exit located nt opposite ends, two independent hollow castings located within the ense :it one end, euch having` n single port on its front side :ind :L series oi' tubular projections` integr-nltherewith on the, reur side, pipes passed through the herul o1' 111e ense into the ports ofthe hollow castings for securingthem in place, and o series of tubes arranged in u pile the one above the other7 euch tube being bent in :L number of return folds, haring the limbs of each fold parallel, as shown, :ind their ends inserted in the tubular projections, by which a tight joint is effected between the tubes und the castings und the tubes nre supported, substantially :is shown.
In testimony whereof we :ifx our signatures in presence ot' two witnesses.
