SPECIFICATION forming part of Letters Patent No. 365,000, dated June 14, 1887.

Application tiled August 1Q, 1886.

l'o LZZ whom, it may concern.-

Be it known that l, ABNEE L. GrLsrRxr, a citizen of the United States,residing at Springfield, in the county of Greene and State of Missouri, have invented certain new and useful Improvements in SteamGenerators; and l 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 appertains to make and use thesame.

My invention relates to steamgenerators; and it consists in the construction, novel arrangement, and adaptation of devices, as will be hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinal section of a generator embodying my improvements. Fig. 2 is a cross-section upon the line x :v of Fig. 1.

Referring Aby letter to the drawings, A indicates the outer walls of the generator, secured to the base-plate B, by means of bolts or rivets I), extending through the lower edge or rim of the outer walls, A, and base-plateB. The said walls A all around extend upward to a point at or near a horizontal line with the top of the re-box, the elevation ot'which rebox may be any height desired, and from which horizontal line the walls A are curved or rounded inward and upward toa line about vertical with the outside of the fire-box, and from thence directly upward to any desired extent, and are provided with a suitable cap, a?, concave on the under side.

C is an outer covering, extending around the walls Aof the generator and secured to the base-plate B in a similar manner, and forming between the walls A a flue or space, c, around the walls A, extending upward and connecting with the smoke-stack, being identical with the smoke-stack D, at the point C, at or nearly on ahorizontal line with the point a of the generator-walls A.

D is a smoke-stack, made of any desired size and shape.

E isa ire-box, placed inside and about the center of the walls A, and its sides e are secured to the base-plate B, by means of a rim riveted or bolted thereto, preferably. extending around the interior of the iire box, forming a shoulder on the base-plate, around the inside of the fire-box, and opening through the baseplate to receive a grate, F, the rim f Serial No. 210,650. (No model.)

of which rests on said shoulder at the lower end of the iirebox. The base-plate B is preferably square, but may be made in any desired form and thickness, with a hole through it about the center and under the fire-box E and grate F, to permit the ashes and cinders to drop through from the tire-box and to admit a draft of air. To the upper end of the lire-box is secured a cap, e, bolted or riveted on. This cap is concave on the under side. To the sides c4 on the outside are secured such number of rods or bars G as may be desired, connecting with the insidel of the upper part ofthe walls A, for the purpose of strengthening the generator.

H is a boiler-flue composed of two walls, extending around theiire-box, midway,or nearly so,bet\veen it and the walls A, and the walls h h are secured at their base to the base-plate B, by most convenient turn of rims bolted or riveted thereto, in like manner as the walls A. To the top of this boiler-flue H is iixed a cap, h2, concave on the under side co-extensive with its walls and riveted or bolted thereto. This boiler-flue may extend up to or near the top ofthe body ofthe tire-box, as may be desired, and is connected at or near the top by any desired number of tubular flues, l, with the fire-box at or near its top, by which the fire-name and heated air pass from the tire-box in the boiler-line; and again, the boiler-flue has a connection, by any suitable number of tubular ilues, J, from its bottom into the ilue ci, at or near its bottom, by which the ilame and hot air pass from the boiler-flue into the iiue c, and from thence around the walls A, and out ofthe smoke-stack D.

To clean out the lues and the water-spaces between' them, openings are made down through the base-plate, which openings are indicated at c3, it, at, and a5, each ot' which is supplied with the usual covering-plates, through which the ashes, cinders, and soot, and also the sediment and water, may be driven out of the generator.

At the top of the boiler-flue H, on one or more sides, if desired, are provided openings into said tlue for the water and steam in the generator, for admitting and shutting ofi1 water and steam when required to clean out the flue o2 and other flueconnections, of ashes, cinders, soot, and sediment, These openings ICG I are supplied with the usual stop-cocks, k2, the

turningbar of which is passed through atube inserted in the flue c2 and the walls A, terminating in a handle outside of the iiue c2.

At and below the water-line in the generator twoA ordinary steam-gages, L and L', for showing the presence of water and steam, are insertcdinto andthrough thefluecaudwallsA.

Steam connecting-pipes M M are shown in Fig. l secured on the inside of the walls A A, and are used to conduct the steam from the generator to the engines, supposed to be secured to the base-plate outside of the flue c2.

N is a reception-pipe, having a stop-cock, n, in it, inserted into and through iue c2 and walls A, ou a level with the upper steam-gage, as shown' in drawing No. 1, and is used for the purpose of filliugthe generator withwater. Over the baseplate and secured thereto, entering the flue c from the force-pump or insulator, and passing inside of that fluevhalfway around the Walls A', is placed the supplypipe Q, made in the usual manner,.and used to supply the generatorwith water when in use.

O is an opening or door, through which to ator proper and forming the smoke-Hue c2,

leading to the uptake or stack, ilue H, leading from the furnace down through the watervspace and into the flue c2, one or more outlets,

M, leading from the steam-dome down th rough .the water-space and out through the boiler? shell and its casing,waterfeeders Q, the braces G, and plates K, for affording access to the lower ends of the water-space and smoke-dues, all constructed andadapted to operate substantially in the manner and for the purposes described.

In testimony whereof I aii x my signature in S. A. HAsELTINE, S. C. HASELTINE.
