VFEED-PIPE FOR BOILERS.
SPECIFICATION forming part of Letters Patent N o. 382,753, dated May 15, 1888.
Application moa April a, iss-1.
To all whom/.it may concern:
Be it known that I, SAMUEL B. BRYAR, a citizen of the' United States, residing at No. 209 Denniston avenue, Pittsburg, inthe county of Allegheny and State ofPennsylvania, have invented certain newand useful Improvements in Feed or Supply YPipes for Locomotive-Boil-v least consumption of fuel; second, to obviate the necessity of watertables in relboxes or furnaces;-thi1d, to give the feed-water the full' advantages of the highest temperature bf the iire beforepdischarging into the boilerjand, fourth, to provide a continuous supply of water to the boiler atthe sametemperature as the water containedtherein. I attainthese objects by the mechanism illustrated in the accompanying drawings,in which-` Figure 1 is a side sectional elevation of an ordinary locomotive-boiler, such as are now in common use, constructed in accordance with my invention. Fig. 2 is an end sectional elevation of the same, taken on the linead Fig. 3 is an enlarged detail side view of one of the feeding-ducts, as partially shown in section the better' to show interior arrangement. Fig. 4 is a rear. sectional elevation of my improved feed-water heater, showing the same attached in position in an ordinary locomotive-boiler. Fig.. 5 is a perspective View of the front of a locomotive-boiler, showing the relative position of the fiues and my improved feed-water heater. Fig. 6 is a side sectional elevation of a locomotive-boiler and fire-box or furnace, in which is shown theentire arrangement of pipes used in connection with my improvement. Fig. 7 is a perspective view of my improved heater detached from the boiler.
The following is a list of parts as designated by the letters of reference on drawings, viz: A, boiler; B, flre'box or furnace; G, feed or supply pipe; D, crown-sheet; E, fire-door; F, water space; G, feeding ducts; h, tubes or sriaiivmsasqe. (No model.;
fines; i, check-valves; J, steam-dome; K', injectors; L, injector-levers;M, valves; N, d1s charge end of; feed ork supply pipe; O, splder.
The feed or supply pipe C, part of which forms theheater, 4is arranged as follows: Beginning at the injector K', it passes thence downward and frontward along exterior of boiler,-
as shown by dotted lines, to the frontend of boiler, there supplied with check-valve i, as shown, constructed, and adjusted to boiler and supply-pipe, as now in use, the feed or supply pipe thence being carried into and through one of the tubes or fines h to rear end of boiler; thence backward and upward through fire-box or furnace B and crown-sheet D into water-space F, there fitted with feeding-ducts G, as shown; thence forming half-circle frontf.
wardand downwardthroughfire-boxorfurnace into parallel tube rorjiiue to front end of boiler;
thencefin halfcircle into another of the paralleltubes or Eines thence through same into iirebox or furnace; thence backward and upward parallel with the first circuit into and through. crown-sheet into water-space, there fitted with feeding-duct G; thence in halfcircle frontward and downward through iirebox or furnace and again into and through tube or iiueI to front end of boiler; thence in a half-circle into an; other of the tubes or fines; thence through same into fire-box or furnace; thence back. wardaud upward parallel with the first and second circuits through crown-sheet into water-space, there fitted with v.feeding-ductG, as shown; thence in a halfcircle frontward and downward through' fire-'box or furnace and crown-sheet into water-spacev of boiler, there discharging water-supply at N, asshown.
The feed or supply pipe is to be constructed of the best material in use to withstand heat. All other appliances are to be constructed and adj usted upon the same as are now in common use. The arrangement of the'said feed or supply pipe in'and through the fire-box or. furnace renders water-tables therein, as now in use, unnecessary, the feed or supply pipe answering the same purpose, the feeding-ducts Gto be con structed and adjusted on feed or supply pipe substantially as shown in Fig. 3.' The water from the boiler, which enters therein, being hot, and following the current in the feed or supply pipe, insures a temperature equal to lthat of the water in the boiler before being ICC discharged therein, thus lessening the danger incurred from or by any sudden changes in the temperature, the boiler not being subject to the strains resulting from sudden cooling, as is now often the case, Fig. 7 showing continuous coil of feed or supply pipe from injector K to discharge end N as detached from boiler.
What I desire t0 claim and secure by Letters Patent is- 1. In combination with steam-boilers, the feed-pipes C, extending through tubes or lues h, and inclined longitudinally through fire-box or furnace B, their upper curls entering crownsheet D, and within water-space F, where it is provided with feeding-ducts G, as described, and for the purpose specified.
2. The combination, with a steam-boiler and feed or supply pipe C in a continuous coil or circuit through tubes or iues L passing within and exposed to fire, of firebox or furnace B, having feedingducts G adjusted thereon within waterspace of boiler, as shown.
3. In steam-boilers, the combination or arrangement of continuous, inclined longitudinal feed or supply pipes C, extending parallel through tubes or lues h, upward and downward through re-box or furnace B, through openings in crown-sheet D at top of furnace, provided with feedingdncts G within waterspace F, and having discharging end N at rear end and bottom of boiler, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
