Be it known that I, MILES PRATT, of Boston, in theloounty of Sufi'olk, andState of. Massaehusettshhave invented an improved Boiler for Stoves; [and do hereby deolare the same to bje fullydesoribed in the following I I,

specification, and represented in the accompanying drawings, of which- Figure 1 is a top view. Figure 2, an end elevation. Figure 3, a transverse section. Figure 4, a horizontal section. Figure 5,- a rear elevation; and s Figure 6, a, longitudinal seotion of it. i h I i i v i h h The nature of my. invention eonsists in a boileras made with a flue to extend upward against its bask j against the same, and to project into the water space, in uianner as hereinafter set forth; also, in the arrange I The advantages of my improvement over a boiler having a flue going up tln'oughitsinternal or water spalee ii are, that myimproved boiler can be made with oueeoveronly, to extend fromjend to end of it, and will hold more 5 water than one of the external size, but with the flue going up through the water space.- 1 i 1 In 'the drawings, A denotes the boiler, B the flue, and U the cover of therboilerf th'e said ooverbeing hing ed to a shelf, D, east or fixed on the top ofthe boiler. Theflue projects hali} way. into} the water sip aoe of the, boiler, or runs up along its back, such back beiug curved "rnward in frontlof the flue, ias represented. Theii ie .1 is open, ,both at top and bottom, it being intended that the lower end ofitheiflue shalljbeplacedi direotly iover i the smoke-discharge opening of a stove, or over anopeuing infthe. top plateof a stove, while thefboiler is set: on or over such opening, the same beinjgso that. thesmoke, as dischar'ged fro n the stove, may pass through register, provided with a; slide-valve, is' applied to the backypart of the: said flue QasQseen atF,iand is forthe purpose of admitting air into the fine as oocasionmay require. Were the flue placed wholly within the boilei l andat its rear part,- there would be likely to beangular spaces between the flue and the rear part" of the boiler 3;: and it would be difficult to' clean these spaees fromeollections of dirt or extraneous matters, when formed therein. When the flue goes through the water space, the boiler has generally to bejulade withtwo covers, arranged on opposite sides of the flue. My arrangement ofthe flue enables the" boiler to bernadejwith butohe cover, as represented in the drawings. 1 h j v i l h I do not claim a stove boiler as constructed witha the to extend up through its water space, but what I dbl e1aim,isi r i The improved boiler sis-made with a ilue arranged against its ,side' or rear, and as having an air-register i applied to such flue, substantially as set forth. i i i I 1 i 5 i 3 MILES PRATT.
