7b a/ZZ whom t may concern:

Be it known that I, CoRYDoN WHEAT, of Geneva, in the county of Ontario, in the State of New York, have invented new and useful` Improvements in Hot-Tater and Steam Boilers, of which the following, taken in connection with the accompanying drawings, is a i'ull, clear, and exact description.

This invention relates to the class of hotwater and steam boilers in. which the watereonipartinent consists of hollow rings ari an ged horizontally one above the other and above the ire-pot and communicating with each other by vertical ducts or ports between the aforesaid parts; and the invention consists in the improved construction and combination of parts which constitute a hot-water and steain boiler oi' superior heating capacity with `great economy in the consumption of fuel.

The invention is fully illustrated in the annexed drawings, wherein Figure l. isat'ront elevation otmy improved boiler with a portion of the inclosing-case broken away to better illustrate the forni of the boiler and its surrouinling tire-fines and heat-retaining battle-plates. Figs. 2 and ."3 are horizontal transverse sections respectively on lines .e .a and l Z, Fig, i. Figs. -iand are vertical transverse sections respectively on lines :i: :r and y y, Fig. 2; and Fig. (i is a detached plan view ot' one ot' the setsV ot' water-heating rings of the boiler.

A represents the 'tire-pot, the wall of which consists ot a hollow annular shell provided with a suitableinlet, e, vfor water. Above this fire-pot and concentric therewith are the wa* ter-h eating pipes P P P, arranged horizontally one above the other, and above said pipes is arranged the steam-deine D, said pipes beingI 'connected with each other and with the hollow tire-pot shell A and dome I) by vertical pipes O O O, which are arranged alternately dianietrically opposite each other. ln such of the pipes O O which are below the water line ot' the boiler I arrange verticalpartitions t f, which extend across the adjacent pipes P P, said partitions servi n gto divide the ascendin current ot' water i'roin the descending current, each of said currents passing halfway arouinl the successive pipes and causing a pert'ect circulation of the waterin the boiler.

P P P denote annular water-heating pipes 0i' smaller circumference than the pipes P P P aforesaid, and arranged inside the same and concentric therewith and communicating with the saine b v radial pipes p p. *etween the pipes P P, I interpose solid walls a o, preterably formed of iian ges cast integral with the said pipes. Around the exterior of the pipes P P, I place a shell which is in direct contact with the exterior of said pipes and forms between the same, and also around the exterior oi the fire-pot A, separate smoke-fines c c c. By the pipes P P, with their walls d o, a perfect con]bustion-chainber, I3, is iornied over the iire-pot A, and with this combustionchaniber the tlues c c are made to communicate by ports l) l) through the walls c! a at one side of the coinbustion-chainber.

The Aflues c c are provided with ports lvl/` at points diainetrically opposite the ports h h, as shown in 2 and 3 ot' the drawings.

C represents the inclosing-case, which forms a smoke-jacket around the 'lines c, and in this sin ok e-j acket I place annular battle-plates d d. The battle-plate il rises from the base ot' the smoke jacket or case C and extends part way the height of the saine. The bat'iieplate d is ot' a greater diameter than the bathe-plate (l and suspended from the top of the smoke-jacket, and has its lowerend terminated below the top ot' the bathe-plate d, said bathe-plates sei-vin g to prevent radiation oit' heat outward Ytroni the case (l, and,by the retention of h eat in the combustion-chambcr 'B and 'fines c c, the heating capacity ot' the boiler is greatly augmented.

In order to permit ot' cleaning the aforesaid smoke jacket or case (l, I torni said case with a cast-iron base, C', which I provide with a door, h, and thebattle-plate (l, I mount loosely on the top ot' the ash-pit, so as to permit ot' raising the said battle-plate and allowing the sootand ashes to be scraped out troni under it and out through the door 71,.

From the top of the smoke jacket crease C projects upward the exit-due f, provided with a damper, if, and from the top of the combustion-chamber l rises an annular Aflue, y, which is extended through the dome-I) and some distance above the same, and from this flue to the aforesaid line f is extended a direct exit-flue, f', provided with a damper, n. From the top ot the iiue g is suspended the maga.- zine on, the lower portion ot' which is surrounded by the annular pipes P P P and is isolated therefrom.

IOO

In the operation of the described boiler the products of combustion ascend from the firepot through the coinbustion-chamber B, and by opening the damper fn, the products of combustion escape througlithe tlues g and f to the exit-[lue f. ',lhis aitords the direct draft required when first starting the tire. After the tire is fairly under way, the damper a is to be closed and the damper t' to be opened. Then the products ot' combustion will pass from the combustion-chamber B through the ports l), thence circulate around through the tlues c r and pass out through the ports h into the smoke-jacket; (l, and from thence escape to the tlue f. In ascem'ling through the combustion-chamber the products of combustion are caused to et't'ectually impinge the pipes P P l and radial pipes p p p and the inner halves of the pipes P P P, and in circulating through the tlues c c c they v are brought into intin'iate contact with the exterior of the said pipes and olf the lire-pot.

fr represents the pipe which conducts the steam or hot water to the usual radiators in the apartments to be heated.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
