WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 633,644, dated September 26, 1899.

Application filed April 15, 1899. Serial No. 713,192. (No model.)

To (all whom, t may concern.-

Be it known that I, CHARLES HUsr FOX, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and use? ful Improvements in Water-Heaters, of which the following is a specification.

Myinvention relates to water-heaters of the class intended to supply heat or hot water to buildings, its obj ect being to provide a heater adapted to accomplish either or both these purposes with one apparatus, and also to provide a simple construction of removable and interchangeable parts or elements, admitting repairs with but temporary cessation of operation.

Apparatus embodying my invention is illustrated in the accompanying drawings, in which- Figure l is a side elevation, partly in section, of my improved heater; and Fig. 2 is a top plan View of same with the smoke-dome removed.

Referring now to the drawings, A designates a water-jacketed shell of plain cylindrical construction constructed in the usual manner of outer and inner shells a a2, riveted to upper and lower rings b b2, provided with a grate c and smoke-dome c2 and the usual nre and ash-pit doors CZ d2, which may be furnished with a heat-regulatin g device B of any approved description. These parts do not differ materially from ordinary constructions and will be readily understood without a more detailed description.

Arranged concentrically within the jacket A, above the fire-grate, are a series of vertical manifolds E, consisting of upper and lower headers e e2, united by parallel tubes t. I prefer to form the headers as centrally open segments or triangular structures, as indicated, and arrange the connecting-tubes in divergent lines extending at the sides and back of the headers from a single tube at the apex, thus giving to each manifold independently a considerable heating-surface. Vhere the apparatus is to be used for a single purpose, all the manifolds E are connected to the water-space of the jacket A by branch pipes e5 es, tapped into the upper and lower headers e e2, respectively, and thence into the inner shell a2. These connections are so made as to be easily detachable, so that when necessary to remove a manifold for repairs the apertures of the shell a2 can be temporarily plugged and the apparatus still used without the absent manifold. In case it is desirable to use one or more of the manifolds for an independent purpose-for example, as a special water-heate'r for a bath-sleeves X are inserted through the outer and inner shells a a2 of the jacket A for the upper and lower connections of a given manifold or set of manifolds E, and the connections e5 e6 are carried outward through said sleeves and thence to a suitable tank provided with the usual connections with the water-main. When in use, I prefer to place a plate p centrally on the top of the manifolds, as indicated in Fig. 3,

to compel the heated air and gaseous products of combustion to pass outward and around and through the headers of the manifolds, thus reaching all sides of the tubes freely.

The operation will be readily understood. The tube manifolds being exposed to the greatest heat, the circulation of water therein will naturally be upward. While the outer shell of the jacket is exposed to radiation of heat and is therefore coolest, the sheet of wa ter immediately adjacent thereto will circulate downward.

The construction and form of the tube; manifolds, as will be seen, adapt them to their consecutive positions and relations within the cylindrical shell, leaving substantially parallel spa-ces between, while the central openings through the manifolds allow the heated gases to pass freely through and between the sets of tubes of each manifold, as between adjacent manifolds.

I claim as my invention and desire to secure by Letters Patent of the United Statesl. A water-heater consisting of a waterjacketed shell combined with a plurality of radially-arranged manifolds, each consisting of upper and lower headers of substantially segmental form with central perforations, united by tubes arranged around said perforations, and each header having a connection with the water-space in the jacket, substantially as described.

2. A water-heater consisting of a waterjaoketed shell, combined with a plurality of radially-arranged manifolds each consisting Ioo of an upper and a lower header united by tubes, atubular connection leading from each header into the water-space of the jacket, and a deieotor-plate disposed centrally within the heater above the upper set of headers and overlapping the inner edges thereof, substantially as described.

3. In a water-heater of the character indi-L cated, the combination, with the water-jacketed shell, of manifolds arranged in concentrio series connected with the water-space of said jacket, and other manifolds arranged in the same concentric series with branches extended independently outward, without connection with said water-jacket, substantially as set forth.

4. A water-heater consisting of a cylin-
