To all whom it may concern.

at Lomax, in the county of Henderson and Eltate of TlllIlOlS, have invented certa1n new and useiul Improvements 1n l-lot-Vllater Heaters; and l[ do hereby declare the following to be a lull, clear, and exact descrip-,

tion of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

Particularly, my invention has for its object to provide a hot water heater or boiler of simple construction and exceedingly high elhciency; and to such ends, generally stated,

the invention consists of the novel construction and combination of parts hereinafter.

described and'defined in the claims,

For convenience, this device will be here inatter designated as a hot water heater, it being 'Lmderstood, of course, that this term includes a hot water boiler.

The present invention is directed chiefly to improved construction and relative or rangement of the sections of the heater whereby an exceedingly large amount oi":

heat absorbing surface is exposed to the flames. In the drawings, the invention is illustrated as incorporated in an upright cylinder of the water heater, but it will, of

, tures oi the invention may be incorporated Wild Referring to the drawings, wherein like characters indlcate llke parts throughout the several views; a

Fig. 1 1s a rear elevation showing the preferred form of the heater, some parts belng broken away and some parts being; sectioned;

ltig. 2 is a view partly in side elevation butchiefly in verticalsection on the line a e of Fig. l;

3 is a plan view of one of the intermediate sections of the heater; and Fig. i is a horizontal sectlon tairen ap proximately on the line 4tl oi? Fig. l.

The lirepot section 5 of the heater is set on a suitable base shell 6 that affords an ash pit, is providedwith the customary ash door *l' and is equipped with a suitable grate, 8. The fire pot section 5 is formed with dou e all to afiord a surrounding water chamber E213 V .chamber 9 into the lower portion of which he 1t known that l, Fnnonnron: @l. /Van- LING, a cltlzen ot' the United States,res1d1ng opening one or more cold water return pipes 10. At the lower portion of the front oi? the heater, the section 5 is shown as provided. with a suitable clinker door opening .11. and cooperating door 12, and at its upper front portion, the said section 5 is termed with a fuel door opening 13 that is adapted to be closed by a fueldoor 1a which, as

will :presently appear, is oi: such size that it WllhttlSO. open and close a supplemental opening in the lower intermediate section, presently to be described.

In its top, the water chainbertl of section 5, preferably at the baclr of the heater, is provided with a large circulating port 15] In building up this heater any desired number of intermediate sections 16 may be employed. These sections 16 are provided with water circulating; ports 17, and the port 17 ot the lowerintermediate sectlon registers with the port 15 oi the water chain her Above the ports 17, the sections 16, in their top plates, are provided with similar water circulating ports 18. Theport 18 or the lower intermediate section 16 registers with the port 17 of the section 16 that is pluced'on top thereof. The ports 1'? and 18 or each intermediate section are separated byan oblique partition or web 19, (see particularly l1 ig. l, but also note the other views), that is cast integral with thesection.

ltach intermediate section in this cylindrical term. of heater, is formed with annular outer or marginal main water channel 20 that is the tall depthot the section, except at the front of the heater where the vertical depth thereo'l isreduced to afford openings 21. Here it may be noted that the opening; 21 ot the lower intermediate section 16 reg isters with the fuel door opening 13 oi the tire potsection 5 and is arranged to be opened andclosed by the fuel door 1% already noted. The openings 20 of the other intermediatesectional sections, each will be closedby own cleancut door 29;.

Each intermediate section 16 is formed with central water compartment 23 confnectedto the main water chamber 20 only by a neck portion. The said central water is thus spaced. from the sur rounding annular mam water chamber 20,

so as to form a nearly annular or approxi "niately llhshaped tlame passage 2a with the water charnber overlying the aaial portion of the heater. The water chamber 23 is divided by a vertical radial partition 25 that is formed as an inward extension of the oblique partition 19. By this arrangement, of partitions 1.9 and 25, the neck portion of the central water chamber 23, at one side of the partition 25 is connected to the annular main chamber 20 at a point below,

and at the other side at a point above the said oblique partition 19 (see particularly Figs. 1 and a). By reference particularly to Fig. 1, it will'be noted that the intermediately projected or central water chambers flamepassages 24 of the adjacent intermediate sections, while concentric, or following the same general lines, are nevertheless,

staggered or ofi'set radially, so that the flames. in passing upward, will be deflected radially inward and outward as indicated by arrows, Fig. 2, and will thus come into Contact with all heat absorbing surfaces of the sections.

The top or drum section 27, of the heater is seated on the uppermost intermediate section 16, is made hollow to afford an annular or marginal water chamber 28 that is provided in its bottom plate with a port 29 that registers with the port 18 in the uppermost intermediate section 16. The dome section 3' 27 isformed with a central flue opening 30,

' which by a smokepipe, not shown, will be connected to the chimney or stack. One or more of the water lead pipes 31 is tapped into the top of the dome section 28. At the front of the heater, the dome section 27 is forined'with a cleanout opening 32 adapted to be closed by a door 33.

Suitablegaskets or pockets will preferably be placed between the sections of the heater, and to detachably but rigidly unite the sections, the said sections are-preferably provided with, outstanding lugs 34 connected by nut-equipped bolts 35, as shown in Fig. 1. As already indicated, the flames or hot gases, in passing up from theffire pot, are drawn through the nearly annular flame passages 24., are deflected against the inner surfaces of the marginal water chambers 20 and are caused 'to completely envelop the inwardly projecting water chambers 23. Moreover, as they pass upward, the flames or gases are caused to take a sort of zigzag radially inward and outward course in going from the one assage 24: t0 the other, whi h is out of line therewith.

\Vhen the hot gases reach the dome or top section 27, they strike the top and side walls of the interior surfaces thereof, so that by the time these gases reach the outlet 30, the greater part of the heat thereof will have been absorbed and conducted into the water of the heater. Preferably, the outlet or flue connection 30 has a conducting capacity slightly less than the heat oil the approximately annular flame passages 24;, so that there will be a slight choking or retard ing at the very point where the hot gases leave the heater, but have very .lrce circulation between the sections themselves. This prevents waste of heat and gives the hot gases the complete inflow and will cause them to come into good. contact with all ol the inner exposed heat alisorbing surf aces of the heater.

The water, on its upward passage through the heater moves upward, first from the water jacket of the fire pot where it has nl ready been heated to a very considerable ertent, and thence, to the first section H3. Upon entering through the port 15 it is divided into two streams, the main portion being caused to pass completely around the marginal chamber 20 (see arrows marked a, Fig. 4), and a lesser portion being caused to take a circular course through the inner chamber 23, as indicated by arrows marked Z) on Fig. l. These two streams reunite :it the upper side of the oblique partition in and from thence, pass through the top port 18 of the first intermediate section through the port 17 of the second intermediate section and are caused to take a similar divided course through the second intermediate section, and so on, until the hot water finally reaches'the dome section. 27 through its port 2.), and from thence, is drawn to and radiates through the hot water pipes 3'1. The water is thus kept in contact with hot, walls for a com 'iarativcly long time and is caused to make :1. long tortuous course through the heater mid is exposed to :i very large amount of the hot heating surface.

No only is the heater above dcscrilwd very highly Mlicicut. but is of comparatively simple construction and reasonably small cost and may be very easily kept clean so that its radiating sul'l'nce will :|lways have a maXil'nuln healing (,dh'cicno Preferably, the sections, and in ta t. {he entire heater. is made ol cast iron.

hat I claim. is:

1. A heater ol" the class dcscrilu-d com prising superposed sections in contact at their outer portions which are formed as annular water chambers, each section having a central water chamber spaced from said annular chamber except at :1 connecting neck portion thus forming a nearly atinas amiular flame passage, said outer Water chambers having connecting ports alined with said neck portions, inclined partitions in said outer chambers adjacent said ports and having extensions projecting into said neck portions and. central chambers: and forming passages whereby part of the water caused to circulate around said annular chambers and part to circulate through said central chambers around the partition extension therein.

2. The structure set :torth in claim 1, the central chambers of successive sections being of different extent whereby the smoke r p ssages are vertically staggered.

.3. The structure set forth in claim 1, the central chamber being of less height than the outer annular chambers, whereby flame passages are termed in which the flames contact the inner side of the outer annular chambers beneath said central. chambers.

l. The structure set forth in claim 3, the

outer annular chambers being of less height in the :tront portion of said. heater to form clean out passages for the last mentioned frame passages and clean-out doors arranged at the front of said clean-out passages.

5. A heater of the class described comprising superposed sections in contact at their outer portions and formed as annular Water chambers, each section having a central Water chamber spaced from the sectional annular chamber except that a narrow connecting neck portion thus forming nearly annular flame passages, said annular chainbers being of less height at the front of the furnace than at the other portions to form cleanout passages.

In testimony whereof I afiix my signature in presence of two Witnesses.
