CHARLES GORTO, OF ALBANY, NEYV YORK.

STEAM-GENERATOR.

SPECIFICATION forming part of Letters Patent No. 255,107, dated March 21, 1882.

Application tiled October 13, 1881. (No model.)

To all whom it may concern Be it known that I, CHAnLEs GoRToN, of the city and county of Albany, and State of New York, have invented certain new and useful Improvements -in Steam Generators, of which the following is a specieation.

This ,invention relates to that class of boily ers known as magazine base-burning` boilers,77 and has for its object simplicity in construction, cheapness of first cost-,and readiness of repair. Its object is also economy of fuel, enlarged heating-surface, thorough circulation of the water, and complete safety.

It consists in constructing the combustioncharnber somewhat in the shape of the frustum of a cone, and in such manner that a cylindrical water-chamber inclosing a feed-magazine forms the apex thereof.

It further consists in forming an outer cylindrical water-space of two vparallel walls or shells for a portion of their length, the inner shell flaring from a point near the lower end ofthe inner chamber outward until it meets the outer shell, to which it ,isjoined,in 'combination with said inner chamber, and in such manner that an annular dame-space is formed between said inner and outer independent water-chambers, and also the before-described conical combustion-chamber.

. It further consists, in combination with the said inner and outer water-chambers and the conical combustion-chamber, ot'horizontal and vertical detlectin g-partitions, wherebyT the pro= ducts of combustion are first made to take an upward course through the annular chamber between the concentric independent .waterchambers, then horizontally across one-half of the top of the structure, then down a semicylindrical iiue to a point near thc bottom thereof, and then ascending another semicylindrical flue to the uptake or chimney, said semi-cylindrical flues forming ajacket for the outer cylindrical portion ofthe boiler. Soit will be seen that the products of combustion pass over theheating-surface of the generator three consecutive times before they escape to the atmosphere.

It finally consists in circulating` connectingpipes`and other details of construction, which will hereinafter be more fully described.

Referring more particularly to the accompanying drawings, and to the letters of reference marked thereon, Figure l represents a perspective elevation of my improved boiler, a portion of all the shells being broken away for the purpose of showing the internal arrangement of the parts. Fig. 2 illustrates a vertical transverse section of the same, clearly showing the conical combustion-chamber, the peculiararrangemeutof the fuel-magazine,the annular dame-flue, and the mode of connecting the inner andeuter water chambers. Fig. 3 shows a cross-section'on the line 11, Fig. 2; and Fig. 4, a vertical longitudinal section of a relief vacuum-valve.

Like letters of reference indicate like parts in all the figures.

A shows the outer cylindrical water-chamber, formed of one long` sheet, b, on the outside, a shorter shell, a, on the inside, and a coneshaped shell, b, forming'the bot-tom thereof. Y

The shell b is united or riveted in any wellknown manner to the shells b b. This conical shell or bottom forms the sides of the combustion-chamber. One-half of the inner shell,

a, of the outer water-chamber projects above.

the steam-space of said chamber, as seen at m, Fig. 2,and forms a portion of the horizontal partition F of the smoke-chamber. A continuation of this partition across the top of the boiler runs from the said projection and joins the iiange of the uptake, as seen at n, Figs. 2 and 3, in dotted lines, and also in full lines at n, Fig. 2. This partition F' extends over the top of the boiler, and extends centrally down the side to near its bottom, as may be seen'in dotted lines on Fig. l, and the same 011 the opposite side, the purpose of which will be described hereinafter. Y

Referring to the central or inner water-chamber, which is composed of two annular shells, one fitting within the other, but far enough apart to form a narrow space, A', the inner shell ofthe inner chamber is flaring at its upper and lower ends, the top for the ready reception of the fuel, andthe bottom for the ready delivery of the same.

The two cylindrical water-chambers are connected by means of hollow stay-bolts or thimbles below the water-line, and at the top by means of a bent steam-pipe. These hollow stay-bolts perform av double function-i. e.,

that of staying the parts and providing for circulation.

The advantage of circulation in asteamgenerator is of the first importance, as by a perfect circulation of the water it is prevented from being in a quiescent state, which is always deleterious, because it does, when at rest, deposit-its sediment or foreign substances upon the shell ot' the boiler. not only subjecting said shell to blister and burn, but preventing tbe transmission ofthe heat of the furnace through the plate. When water has a lively circulation it keeps the boiler-plate clean and licks up the heat as it sweeps over the plate, thus causing a rapid generation of steam. The boiler being kept clean lasts much longer, for the reason that the contact of water with the plate is not impeded by any scale or sedimentary deposit. Just above the bottom of the angular waterspacc I locate my grate-sur face, and below this point the outer shell of the outer water-space is continued down to the Hoor. This shell forms the ash-pit and prevents falling coals from scattering over the tioor or outside ofthe shell of the boiler, thus avoiding all danger from tire. On one side of the lower portion of this shell I arrange my tiredoor I. This door is adapted to be regulated for the proper supply of air to the furnace, and upon the top ot' the shell or jacket is located acast-iron top, having an annulus which snugly tits the shell. This casting C is provided with a central opening to which is fitted a. lid, c. Through this opening the reservoir is supplied with coal or other fuel, and near one edge of the casting C is another opening, o, which is provided with a flange to which the smoke pipe or chimney is attached. The under side of the top casting forms the upper wall ofthe return-smoke tine.

It will be observed that the inner watercharnber extends nearly up to the t'p casting, so that when the reservoir is being tilled no coals can fall to either side of it. It will be further observed that reservoir for coal being surrounded with water theie is no danger ot' its burning out, as compared with those made of solid iron, which is a great desideratum.

The pipe L, which enters the side ofthe outer 5o jacket and into and down inside the boiler to near its bottom, is designed for a feed-pipe. I extend this pipe down inside for the purpose of relieving the feed-water from the chilling effect cold water has when suddenly fed into the boiler. It is evident, however, that the boiler may be fed from other points. Steam may be taken ott' by means of pipe M.

Safety-valves, water and steam gages, and other appliances used to steam-boilers are not shown. Some changes and modifications may be made in this boiler withontdeparting from the spirit of my invention. I do not therefore desire to be contined to the exact construction shown.

Therefore, having described my invention, its construction, and operation, what I claim as new 1s- 1. The combination, in a stcam-generator,of two independent water-chambers coneentrically arranged, the bottom ot' the outer chamber being angular in cross-section, forming a conical combustion-chamber, and the central water-chamber forming a fuel-magazine and located at or near the apex of said combustionchamber, in the manner shown and described.

2. The combination, in a steam-generator, consisting of the outer water-chamber, provded with aconical bottom, forming a conical combustion-chamber, of the inner water-chamber located at or near the apex of saidcombustion chamber, and which forms a fuel-magazine, and the annular flame-tine formed by and between the inner and outer water-chambers, in the manner set forth.

3. The combination,in a steam-generator, ot' the two independent water-chambers, as described, the combustion-chamber, the annular tiametlue formed between said chambers and terminating at the lower end of the reservoir, and the upper and lower waterconnecting pipes or hollow stay-bolts, constructed and arranged substantially as shown.

4. In a steam-boiler, the combination of the inner and outer water-chambers, connected as described, and forming the annulariiame-chamber and the conical irebox, a segmental portion of the inner wall ofthe outer chamber projecting above the steam-space, the horizontal and vertical partition, and the casting G,fo1'm ing the top of the return-smoke tine, all arranged to compel the products of combustion to take an up-and-down and return course7 for the purpose described.
