' IMPROVEMENT IN' STEAM-GENERATOR.

The Schedule referred to inthese LettereP-aten't and making parta-.vf the name.

To whom. it muy concern 'Be it' known that I, JOHN CARROLL, of Detroit,l

in the countyof Wayne and State ol` Michigan, have' invented a new and useful Improvement in Steam- Generators; and-jdo' declarelthat the following isa true and accurate description thereo-reference.being hadto the accompanying drawing and to the letters of reference marked thereon, and being apart of this specilication, in which-.- l

Figure 1 isa longitudinal vertical section on the linezxiniigZ.

Figure 2 is a transverse-vertical section on th'e line il .'l in iig..

Like letter-sindicato like parts in each figure.

The nature of this invention relatesv to `an iml proved construction of steam-generators, and consists Ain, so'constructing the same that all, or very'uearly all, the productsof combustion ot'thc fuel used in generatingsteam are consumed;` .'thatapvery large and increased 'heating-surface is obtained -and in .a new, in-

genious, and novel arrangement ol' its variousparts.

YIn the` accompanying drawing, -I represent whatis ordinarily termed al locomotive-boiler, with bori`- zontal fines, and vertical lines in the smoke-stack.

A represents a fire-box, provided with usual fire'- grates, B, and aslrpit Gand bridgewall D.

E is a s'eri'cs of'tlues, with spaces `between the same,"

upon the grates B,.and whose top enters the smoken chamberJ, where itterminates in the perfbratedtubes K. The sides of the conical cylinder within the firebox are perforated, as shown, for the purpose herein# after explained.

L is a suspended bridge-wall, also hollow, and counected, by means'of the pipe M, with the water-space of the boiler.

N is a door or trap, opening from the outsideinto the Vcombustriolrohamber F, through which ashes or dirt may be withdrawn; i

O is a perforated pipe, secured at its ends to the sides of the combustion-chamber, through which it passes directly in front of the upper part of the suspended bridge-wall L, and allows. a passage for air from the outside of the boiler into the said combustion-chamber. v

' 1 is a large tine leading from 'said combustion-chamber to the smoke-box Q. Y It is a series of iiues leading' from said smoke-box to the'smoke-chamber J.

S is another series oxiiues leading from said smokcf chamber upward into-the smohesmck.

land against the current of air which isradmittcd through the perforated pipe O, 'whence all the proda are water-spaces in the boiler. p

The ues I, Rand S are secured to. and through suitabletube-sheets in the usual manner. Fire being kindled in the fire-box, the ame is broken up, in its passage into the combustiou'lchamf ber F, by passing through the spaces between the reotangular l'lues E, and, upon their entrance'to said combustion-chamber, are mingled* with the currents of heated air which pass through said dues E from beneath the grates, while the heat arising from said flames is deflected over the top of the delicc'tor G ucts of combustion, ,being throughly mingled with the airadrnitted, as described, are carried, being partially consumed, through the flue P, to the smoke-box and thence, through the tides R, to the smokechamber J, where they are again brought into contact with flames and heat, which are carried into said oham- Y ber through the conica] perforated cylinder I, and distributed through the perforated pipes K,`such Contact producing a. thorough combustion of the remaining smoke and gases, while the heat and the remaining smoke, should there be any, will pass upward through the' tlues S to the smokefstack,

I-do not pretend to be `the,original and first inventor of'an` igniting communication between the irc-A box andthe chamber above it, but only of thespeciic construct-ion and arrangement shown and described,

wherein the hase of the cylinder-ZI rests. upon' the grates B, and the perforated tube K is connected withl the cylinder I, and arranged within the smoke-cham ber J, as shown and described. I

What I claim as my invention, and desire to secure by Letters Patent, is-

1; The cylinder 1, resting upon the grates B, and having connected therewith the 'perforated tube K, placed within the smoke-chamber J, when the several parts are constructed -and arranged as described and shown, and as and for the purposes set forth.

2. ,The deliector G, hollow, and connect-ed with the water-space of the boiler by the pipe H, and resting above the lilies E and bridge-wall D, substantially as herein designated.

f `3. The construction of a steam-generator, wherein the grate-bars B, ashfpit O, bridge-wall D, retangular fines E, combustion-chamber F, deiiector G, pipes H M, cylinder I, perforated pipes K, smoke-chambers J Q, suspended bridge-wall L, door or trap N, perforated pipe 0, and lines P R S are arranged, relatively to each other and the water-spaces c of the boiler, substantially as and for the purposes herein shown, set forth, and described.
