ATTACHMENT FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 477,151, dated J une 14, 1892.

Application filed January 15, 1892. Serial No. 418,143. (No model.)

To @Z whom, it may concern:

.Be it known that l', CHARLES K. PIcKLEs, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Attachments for Steam-l3oil ers, of which the following is a full,clear, and exact description, reference being had to the 'accompanying drawings, forming part of this specification.

My invention relates to certain features of novelty in that class of attachments for steamboilers wherein a downdraft and a water-tube grate are combined, the object being to sirnplify the construction and facilitate the ease with which the attachment can be applied and repaired.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is an enlarged detail vertical trans verse section taken on line I I, Fig. V. Fig. II is a similar View taken on line II II, Fig. V. Fig. IIIisadetail vertical section taken on line III III, Fig. IV. Fig. IV is a similar view taken on line IV IV, Fig. III. Fig. V is adetail vertical section through the setting of the boiler, showing part of the boiler and the at- Fig. VI is an enlarged Vertical section taken on lineVI VI, Fig. I. Figs. VII and VIII represent slight modifications in the manner of forming the watertube sections and arranging the water-tubes therein.

Referringr to the drawings, l represents the boiler, having the usual setting 2.

3 represents the iire-boX, and et the aslrpit. The grate of the fire-box is composed of watertubes*by preference a lower series of large tubes 5 and an upper series of small tubes 0 being used. These tubes communicate at their inner ends with a large connect ing-pipe 7 and at their outer ends with alarge connecting-pipe 8, the manifolds communieating With the boiler through vertical pipes 7 and 8f.

My invention relates particularly to the manner of connecting the pipes forming the grate to the manifolds.

9 represents hollow castings or sections iit ted on the pipe 8 and communicating with the interior of the pipe through openings l0. (See Figs. III and IV.)

1l represents copper or other suitable gaskets located between the sections El, so as to form tight joints between thenrto prevent the escape of water passing through the water-tubes of the grate and through the sections and manifolds. It will be observed that each section hasa hub-like portion iittingthe manifold, and from which there is an extension, 6o into which the ends of the tubes 5 and 6 are fitted, and by preference the sections are so formed that each alternate one will receive two of the tubes 5 and one of the tubes 6, while the intermediate ones receive one of the tubes 5 and two of the pipes (i, as shown in Fig. III. Any suitable number of these sections are used, according to the width of the fire-box, there being a sufficient number of them employed to extend across the lire-box, 7o as shown in Figs. I and II.

12 represents castings or sections located on the inner connecting-pipe' and into which the inner ends of the tubes 5 and 6 are fitted, as shown in Figs. I and VI. These sections l2 are the same and are arranged the same on their manifold, with which they communicate, as the sections 9; but by preference the extensions of these sections dependin a down wardly direction instead of projecting in an 8o upwardly direction, as do the sections 9, the object being to provide for the pipe Z being above the water-tubes, so as not to interfere with the draft of the furnace, which is downwardly through the grate and up through a S5 space 14 between the manifold and the bridgewall let of the furnace, as indicated by the arrows in Fig. V. rlhe inner ends of the tubes 5 and G are screwed into the sections l2 after the sections are putin place ou their connect- 9o ing-pipe, the tubes being inserted through the sections 9, which have removable plugs l5 to permit the insertion of the tubes. After the tubes are screwed into the sections l2 their outer ends are expanded in the sections 9, as shown at 16, Fig. IV. It will thus be seen that when either of the tubes are burned out it can be easily and quickly removed and replaced by another, and in caso one of the sections'should burn out (there will be no danroo ger of the connecting-.pipes burning out, for the reason that they are covered Vand protected by the sections) one of the couplings 17, by which the manifolds are connected to the pipes 7a and 8, can be removed and the connecting-:pipe drawn outV past the section, which it is desired to replace, and when Ithe*` new section is inserted, the .connecting-pipe? forced back to its normal position, and the couplings again applied, so that a `construe-. tion of this kind affords the best facilities, not only for the rst building up or construction of the attachment, but also for repairing itin any part which is likely to need repair.

In Fig. VII, I have shown the extensions of f the sections 9 projecting in an inwardly ini stead ofa downwardlydirection,in which case the tubes would be screwed into the sections; 9, the sections 12 being ypr@vided with the re= movable plugs to rpeninirt the insertion ,of the l tubes, which would be flanged in thQ-Sections 12 after they are screwed finto :the sections 9. In Fig. VIII, Ihavesihown fthe sections-,prei vided each with a single lateral `Wingffor sup- Q porting the tubes 6, and, ifdesired, `the sec tions may be formed so -as to lreceive .only'the` tubes 5,` the tubes -6 being omitted altogether. This would be accomplished by simply leaving o the latter `extensions 118. (Shown in Fig. VIII.)

I claim as my invention?- 1. In yan attachment for steam-boilers, Vthe combination of the manifolds .consisting of connecting-.pipes and independent sections mounted on said connecting-pipes, with the furnace-grate iconsisting of water-.t ubes sef cured to said sectionsand communicatingbe-g tween said manifolds, substantially as and for the purpose set forth.

2. In `an attachment for steam-boilers, the:

combination Aof the manifolds consisting of the connecting.- pipes, the removable independent sections mounted on said connecting-pipes, and openings 10 in said pipes, with the furnace-grate consisting of water-tubes connected to said sections and forming communication between the manifolds and suitable communications between the manifolds and the boiler, substantially as and for the purpose set forth.

3. In an attachment for steam-boilers, the combination of the connecting-pipes, a numberof independent removable sections mounted on the pipes and communicating therewith to form manifolds, water-tubes forming the vgrate of the furnace and fitting into said sections, and vertical pipesformingeommunica tion between the vmanifolds and the boiler, .the rfront manifold being located beneath the Watentubes and the inner manifold fbeing located above fthe waterft-ubes, substantially as shown `and described.

4. In an attachment for steam-boilers, the combination .of the connecting-pipes, removl able sections fitted on the connecting-pipesto form manifolds, vertical pipes jointed to the manifolds and forming a communication between the manifolds Vand the boiler, and water-.tubes forming the grate of the furnace,

: said water-.tubes being screwed into the sections `of the inner manifold and expanded into the sections of the outer manifold, the sections .of said outer manifold being provided with removable plugs, all substantially as and for the purpose set forth.
