, Be it known that we', JOHN S. Manin and HENRYA. SGHELEMAN, both4 citizens of the United States, residing in the clty and 5. county of Philadelphia, State of jPennsylf van ia have ,inyentedfa new and useful Aux- ;iliary Water-Heater," of which the followy ing isaspeciication y l ",Oiixminvention' consists of an improved D wateryfheater,,y particularly adapted to be supported within `the fire-pot or ,combustion ...chamber of 'la furnace, stove or gas heater. .It further consists of a heatingchamber having radiating hollow branches to proi vide -a large heating surface.

It further consists ofa heating chamber having a water feed pipeentering from above lthrough `thetop of thesaine and sur,-

- rounded by the discharge-pipe.' p

i It further consists of a heating'chamber having a water feed pipe entering it from above through the top of the same and`extending intov a pipe extension.

-Itfurther -consists of other novel feai tures of construction, all as will be hereinafter fully set forth.-

For the purpose of illustrating our'invention, we have` shown in the accompanying ldrawings a preferredembodiment therel of which is at present preferred by us, since vthe same has been found yin practice to give satisfactory and reliable results, although it is to be understood' that the various 1nstrumentalities of which-our invention con- `-Eists can be variously arranged and organized and that our invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described. v

` Figure 1 represents an axial .section of our lmpr'oved water-heater. Fig. 2 represents anaxial section of the heater, indicating a manner in which the heating chamber Vma be extended. Fig. 3 represents a trans- V., se section of theheating chamber, taken on line zie in Fig. 1. Fig. 4 represents an elevation of a furnace in whichl our, improved -water heater is suspended, parts of 'the jacket and furnace being broken away and removed.

erably of cast metal, formed with radiating hollow branches, 11, makin it substantially star-shaped, and also ormed at its top and bottom with internally threaded central nipples, 2 and 3, respectively. A pipe, 4, is screwed into the upper nipple 2, and having a coupling, 5, screwed upon its upper end, which coupling has a lateral nipple, 6, into which may be screwed a pipe for conveying the heated Water.v A sup lypipe, 7, 1s axially secured in said coup ing and extends axially through the hot water discharge pipe 4, down to about the middle of the water-heating chamber, where a disk or baiilelate, 8, surrounds the same and has its e ges integral with or closely fitted against the junction points yof the sides of the radiating branches of the chamber. The bottom opening of the heating-chamber is closed by a plug, 9. If it is desired to extend the heating surface of the chamber, a pipe or waterle ,'10, may be secured into the bottom `nippe of said chamber to extend farther downinto the fire-pot o'r com' bustion chamber, and the lower end of said pipe is closed by the plug 9. When the heater is provided with the water-leg, the supply-pipe is extendedto near the lower end of the latter.

In Fig. 4, the heater is illustrated in place in a furnace, the stove of which is indicated by the numeral 12, and between which stove and the jacket, 13, the heating chamber, 14, is formed. The discharge-pipe 4 is suspended by a coupling, 15, or similar means resting upon the edge of an opening in the top of the stove.

As cold water'enters from above, it is warmed by passing through the hollow column of hot water ascendin on the outside of the supply-pipe 7 throng the dischargepipe 4 and thereupon such water enters the heating chamber at the hottest point, at or below the bottom of the same, where it is directed outwardly b the radiating brano es of said c amber, being heated, whereupon the heated 4water asce ds in hollow celu/Inn tirou'gh the dischCyZge-pipe to a boiler or whatever d stinati n may be provided for it. If /the'lizatin chamber is placed some distance above th normal surface of the fueledaud it is de'L sired to provide additional heating surfac, the downwardly extending tube or wate leg, illustrated in Fig. 2, is employed and addi'fgnal heatin ofthe water-in such water-leg is attaine in the fuel-bed.

It is evident that one or more heatingchambers may b e placed in a gas-heater or connected 'in a larger pipe so asl to be sur- Vrounded by steamer smoke as Well as in l the fire-pot or combustion-chamber of a fur- --nace orfstove burning solid fuel. 10

n heating-chamber from above, the Water in Byproviding vthe inlet-pipe entering the said pipe will be preheated before entering such chamber, and there will be no interference by the heater with the tir pot or comi' of the supply-pipe will pass around the edge I '.tortuous channels for the Water so as to expose the same to the heat for a comparatively long space of time, and the star-shape of the chamber will provide a large heating surface. f

Having thus described our invent-ion,

what We claim as new and desire to secure p by Letters Patent, is

1. In a device of the character stated, a

vheating-chamber, a .discharge-pipe extending from the top of the same, a supply-pipe projecting axially through said dischargepipe into the interior of said chamber, and a baille-plate secured to surround said supplypipe above the lower end of the same. V 3 2. In a device of the character stated, a heating chamber having radiating branches, a baille-plate within `sald chamber and having its edges extending to the junction points of the Walls of the radiating branches 4 of the chamber, a discharge-pipe extending from the top of the chamber, and a supplypipe projecting axially through the discharge-pipe and opening below said baille'- plate. 4

. 3. In a device of the character stated, a heating-chamber having radiating branches, a discharge-pipe extending from the top of said chamber, a supply-pipe extending axially through said discharge-pipe and into 5 the chamber, a baille-plate surrounding said supply-pipe abovgthe lower end of the same, and a Water-leg extending from the bottom of the heating chamber.
