SPECIFICATION forming part of Letters Patent No. 574,738, dated January 5, 1897. Application filed March 13, 1896. Serial No. 582,997. (No model.)
Y ing drawings, is a full, clear, and exact description.
This invention relates to the class of steamboilers which are placed in an upright position and have direct-draft fines extending through them; and the invention consists inv an improved construction and combination of the constituent parts of the boiler and auxiliary devices connected therewith, all arranged in a most compact manner and organized to contribute to materially enhance the efficiency of the boiler and insure its safety and durability.
The invention is fully illustrated in the annexed drawings, in which- Figure lis a front elevation of a steamboiler embodying my invention. Fig. 2 is a horizontal transverse section on line X X in Fig. 1. Fig. 3 is a vertical transverse section on line Y Y in Fig. 2.

Fig. 9 is a horizontal transverse section on line T T in Fig. Fig. 10 is a horizontal transverse section on said line T T, showing a modification of the shape of the fire-box and a plain bridgewall. Fig. 11 is an enlarged transverse section of the upper end portion of the sedimenttrap pipe, showing the attachment of the overflow-pipe; and Fig. 12 is an enlarged plan view of the air-induction pipe of the lire-box- Similar letters of reference indicate corre-.
sponding parts.
A represents the boiler proper, the shell of which is preferably of cylindrical shape, placed upright and extended below the lower nue-sheet a, as shown in Fig. 3 of the drawings, for the purpose hereinafter explained. Through said boiler extend the series of vertical direct-draft fines c c, secured in the usual manner to the aforesaid lower fluesheet a' and upper hue-sheet b, riveted to the upper extremity of the boiler-shell', upon which is mounted the smoke-box O, which is elongated so as to project laterally from the boiler and has the smoke-stack D connected to the extension. The top of this smoke-box I provide with trap-doors CZ d to obtain ready access to the interior of the smoke-box and to the hues c c for cleaning and repairing the same. Directly under said boiler is the combustion-chamber E, formed by the hue-sheet a, constituting the crown of said combustionchamber, and by the Vertical wall e, which is riveted at its bottom edge to the aforesaid downward extension of the boiler-shell and is sustained a sufficient distance from said shell extension to form a water-space e', which communicates directly with the interior of l the boiler and surrounds the combustionchamber.
F denotes the hre-box, which extends laterally from the combustion-chamber and is formed with water-legs ff along its sides and across its front and with a water-crown f eX- tending the entire length of the fire-box and communicating with the water-space of the' boiler A, as shown at gin Fig. 3 of the drawings,.while the water-legs connect directly with the water-space e, surrounding the combustion-chamber. G represents a bridgewall which is interposed between the firebox and combustion-chamber, and over this bridge-wall is a fire-deflector H, which extends from the crown of the fire-box downward partway into the combustion-chamber. The deflector thus arranged forms a tortuous passage for the products of combustion from over the bridge-wall downward and thence upward to the vertical flues c c. The base ofv the boiler is thereby thoroughly heated. This deflector is formed of a hollow metallic chamber joined to the crown-sheet h of the iire-box and to the flue-sheet a and water-space e', so as to be charged with water direct from the water-crown f' and from the boiler A, and permit the water to pass through said deiiec- IOO tor to the water-space surrounding the coinbustion-chamber. In order to prevent the sediments from collecting in said delector, I form the lower or closed end thereof inclined to the water-space e at the side of the combustion-chamber, as shown at i in Fig. S of the drawings. Said deflector forms a partlycontracted throat 7c over the bridge-wall, and causes the products of combustion to be more thoroughly distributed throughout the combustion-chamber E and through the tlues c c, which distribution of the products of combustion is aided by the location of the smoke-stack D over the side of the boiler opposite to that toward which the products of combustion are first conducted by the defiector H.
To further insure the aforesaid diffusion of the products of combustion, I form the top of the bridge-wall inclined, corresponding to the inclination of the extremity of the delector II.
In order to insure proper combustion of the gases generated in the fire-box, I form the bridge-wall G with an internal air-passage Z, which extends lengthwise of said wall and part way the height thereof and has secured in its top portion a twyer-iron m, extending the length of the air-passage and provided with a longitudinal slot, by which it communicates with the fire-box. Said air-passage is provided with a suitable damper Z for con trolling the inlet of the air, which damper may be located either in the ash-pit I, as shown, or placed in any other suitable or convenient location.
In the twyer-iron is placed longitudinally a steam-pipe n, receiving steam from the boiler A by a suitable pipe n', and hasV projecting from it and into the slot of the twyer-iron a series of jets or nozzles n,which are arranged in pairs convergent toward the fire-box, so as to thoroughly coinmingle with the air drawn from the twyer-iron by the suction. produced by the force of the steam ejected from the nozzles n. The inflowing air is thus heated, and, in conjunction with the steam forced through the gases rising from the fire on the grate I', causes said gases to ignite. The products of combustion passing through the throat over the bridge-wall and effectually impinging the water-charged deiiector I-I niaterially enhances the efcieney of the boiler. The flues c c I place in groups with deiinite radial water-passages c' between the groups, as shown in Fig. 4 of the drawings, and at or near the water-line of the boiler and at points in line with the water-passages c' c I tap the boiler with blow-off pipes o o o, which are united -at the exterior of the boiler by a pipe o', provided with a blow-off cock p.
Tofurther guard against accumulation of sediment in the boiler, I employ the trap-pipe P, which I preferably place inside of the boiler, so as to be heated thereby. This pipe is closed to the water-space of the boiler and has the feed-water pipe lr connected to its lower portion. To the upper portion of the said trap-pipe is connected pipe s, which is extended down, preferably, into the waterspace e', surrounding theicombustion-chamber, and thus admits the feed-water to the boiler at the coolest part thereof.
The base of the trap-pipe T has connected to it a blow-off cock tto permit the sediment to be expelled from said pipe.
I do not limit myself to any specific shape of the fire-box, which may be either rectangular, as shown in Figs. 2, G, and 0 of the drawings, or with converging sides, as repre` sented in Fig. IO of the drawings.
That I claim as my invention isl. The combination of an upright boilershell, a smoke-box on top of said shell, a coinbustion chamber under said shell, directdraft lues extending vertically through the boiler-shell, the fire-box extending laterally from the combustion-chamber, a bridge-wall interposed between the fire-box and combustion-chamber, and a deiiector extending from the crown of the lire-box over the bridge-wall and with an inclination part way into the combustion-chamber7 substantially as set forth and shown.
2. The combination of an upright. boilershell, a combustion-chamber directly under said shell, a smoke-box on top of the boilershell, direct-draft lues extending from the combustion-chamber to the smoke-box, awater-leg surrounding the combustion-chamber and communicating with the interior of the boiler-shell, the lire-box extending laterally from the combustion-chamber and formed with a water-crown and with Water-legs on its sides and front communicating with the Water -leg of the combustion chamber, a bridge-wall interposed between` the iire-box and combustion-chamber and ahollow watercharged deiiector extendingfromthe watercrown rearward and downward into thecoinbustion-chamber andconnected to the waterlegs of the latter, substantially as described and shown.
3. In combination with the upright directiiue boiler proper and a smoke-box and combustion-chamber respectively on top and directly under the said boiler, of a fire-box extending laterally from` said combustionchamber and formedwitha water-crown, a hollow deflector extending from said crown into the combustion-chamber and charged with water and havingits extremity inclined toward the side of the combustion-chamber, as set forth.
