STEAM-BOILER.

SPECIFICATION forming art of Letters Patent No. 655,018, dated my 31, 190%). Application filed February 28, 18984 Serial No. 672,010. (No model.)

To all whom it may concern:

Be it known that I, REINHARD SCHEIDLER, of Newark, Licking county, Ohio, have invented certain new and useful Improvements in Steam-Boilers for Traction-Engines, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same. 1

My invention relates to improvements in steam-boilers, and more especially to a bbiler fortraction-engines .and locomotives;

One object is to make the steam-dome and the smoke-flue in one and the same casting that has the smoke-flue formed centrally thereof and has a steam-chamber formed around the flue and having its opposing walls strong and durable and adequately connected together by internal stays integral with the casting.

With this object in View and to attain certain other advantages hereinafter mentioned the invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure I is a side elevation, partly in section, of a steamboiler embodying my invention. Fig. II is a vertical section on line II II, Fig. I, looking in the direction of the arrow; Fig. III is a vertical section on line III III, Fig. I, look ing in the direction of the arrow. Fig. IV is a transverse section on line IV IV, Fig. I.

Referring to the drawings, A designates the boiler proper; a, the smoke-box,formed at one end of the tubed portion of the boiler; B, the upright smoke-flue, and O the steamdome. Flue B and dome C consist of one upright casting suitably secured at its lower end to the top of the smoke-box. The said casting has the smoke-flue forming passage-way B extending vertically therethrough and in open relation at its lower end with the chamber of the said box. The said casting has a steam -donie-forming chamber 12, formed around the smoke-flue. The outer or surrounding wall or walls of chamber 1) are somewhat thicker than the said chambers inner wall or walls, and the said opposing walls are connected together, and consequently reinforced,by any suitable number of suitably a'rranged webs or stays b", that areintegral with the said walls. The top of the boiler, preferably near the smoke-box, and the lower por tion of the steam-dome are connected together by a pipe D, that is suitably secured to the boiler-top and dome and establishes open relation between the steam-space of the boiler proper and the'lower portion of the steamspace of the dome. E designates a pipe that communicates with and leads from the upper end of the steam-space of the dome to'the engine-cylinder, (not shown,) wherein the steam is utilized.

The dividing wall or walls between the smoke-flue and steam-dome chamber is extended upwardly above the domea suitable distance to form an upward extension of the. said flue.

It will be observed that the combined smoke-flue and steam-dome, being made of a reinforced single casting, isfree from seams or joints and requires no riveting in its construction and is not liable to leak nor to suecumb to the steam-pressure in the domechamber, nor is it liable to be affected or inj ured by exhaust-steam and gaseous products of combustion. The domes outer shell is preferably somewhat thicker than the shell that separates the smoke-fluefrom the domechamber, so as to reduce the waste of heat and condensation of steam to a minimum.

The body of the smoke-box consists of two cylindrical shells to and a arranged the one, 65*, centrally within and somewhat smaller in external diameter than the internal diameter of the other, a, so as to form an air-space a between the exterior of the inner shell and the internal surface of the outer shell. The said smoke-box shells are held apart by collars K, interposed between the shells at suitable intervals circu'mferentially of and near the outer ends of the shells. The said collars are mounted upon bolts K, that extend through both shells. These bolts are arranged with their heads at the outer side of the outer shell, and nuts K are mounted upon the bolts at the inner side of the inner shell. The smoke-box at its outer end is provided with a door a. The inner shell a at the top is provided with an aperture a that registers with the passage-way through the the boilers water-carrying portion, of which smoke-flue. Myimproved smoke-box is com parativelylong-lived. The outer shell a or; jacket of the smoke-box will last as long as the said shell is a part, and the inner shell or section ofthe smoke-box when it is burned out for the purpose upon loosening the nuts and withdrawing the bolts that are instrumental in supporting the said inner shell. The latter is therefore removable and of course extends from the boilers tubed or water-carry, ing portion to the outer endof the smokebox. By my improved construction ofsmokebox it is obvious that little heat is wasted:

, The castinggthat, formsthe smoke-flue an-di steam domeis-provided at its lower end with a downwardly-projectingflange Okthat extends-around" the aperture of of the smoke box and engages the external surface of the outershell of the smoke'-box-,and consequently obstructs oommunication between the path" ofzthe productsof combustion and the air-' space between the inner and outertshellsof" the smoke-box; The said casting has its smokerflue-formin g :portion. extending: below the'dome-formin g portion, and the said down? ward extension atits lower end and'abovea flange O is provided with a laterally-project in g external flange-C that engages the external surface-of the outer shell of the smokebox: Bolts 0. extend throughthe said-flange O and through-both shells of the smoke-box; The bolts are arranged with their heads at the up per sidesiof the flange. Nuts are mounted upon the bolts at theinner surface'of the inner shell of the smoke-box and collars 0 are mounted upon :the: bolts between the two. shellsof vthe smoke-box: The saidcollars .0 arerinstrumental in bracing apart the two: shells-and reinforce the'support for the cast: i g rthat forms :thesmoke-flue and steamy dome, The said construction rendersthe said cast-ingreadily removable, and of course-the said nuts andbolts arewithdrawn to accome modate-the removal of the inner shell of the" smoke-box;

What I claim is.-

1.: As an article of manufacture, thedome 0 having. the centrally-located open-ended upright passage-way B, the chamber 1) formed around the surrounding wall of the aforesaid passageway, and the webs -or stays 1) connecting the said Wall with the outer wall of the chamber, which last-mentioned wall is thicker than the first-mentioned wall, substantially as shown, for the purpose specified. or requires repairing can be: readily removed- 2. In a steam-boiler, the combination with the tubed water-carrying portion of the boiler,
