, A plication filed Meantime. Serial No. 464,974. (No model.)

To all whont it ntay concern:

Beitknown that I, J UDSON W. WARNER, of Oneida, in the county of Madison and State of New York, have invented certain new and usefulImprovenientsinBoiler-Furnaces; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification. The present invention is a sectional boiler especially designed for heating purposes, and is an improvement upon the boiler for which I was granted Letters Patent on the Sthday of September, 1891, No. 459,243; and it has special reference to the construction of the boiler sections whereby furnaces of different the novel arrangement of the water circulatfing pipes in the grate; and in the'novel construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings: Figure l is a perspective view, partly'broken, of my improved sectional boiler. nal central vertical section, and part side elevation of the boiler.

ofsaid sections; Fig.5 is a face view of an intermediate section. Fig. 6 is a view of the rear section. Fig-:7 is a face view of the fire box dividing section. Fig. Sis a detail. 1

As shown in Figs. 1 and 2 the'boiler has two fire boxes, one of which is supplied with fuel by hand as in ordinary surface burning furnaces; and the other is supplied with fuel from a reservoir as in self-feeding furnaces.

The fire boxes are situated one behind the other, so that the heated products of combus:

rangement forming a very/satisfactory boiler for heating large buildings; I have further.

provided numerous brush openings in the sections, and between the sections, so that the entire system of dues can be readily cleaned without anyone having. to crawl into the boiler, and without taking the sections apart,

and some of these brush openings or passages perform a most important office in assisting in establishinga thorough circulation of heated products upward between and around the water legs, and in a natural course from the fire to the smoke flue, without diminishing the surface exposedtothe radiated heat of,

fuel reservoir sections D,'E, followed by another section B,and arear sectionF. Twelve sectionsin all. 7

Section A consists oftw o vertical hollow water legs A A connected at top .by atransverse Water holding limb or portion A below which is another transverse water-holding limb A the openingbetween said limbs and the legs being closed by a door a by which access canbe had to the fines.- Q

Intermediate limb A andthe bottom of the sections is a transverse hollow limb A4 which forms the front wall of the fire chamber 1.

The opening between limbs A A4, and legs A is closed by a door a throughwhichac- I will now describe the boiler cess can be had to the v fire ehamberplg The bottom of the water legs maybe; connected I by a transverse hollow limb A and the opening between the limbs A ,A ,and legs A'- may be closed by a door a through which access can be had to the ash pit. The front section may have lateral flanges A on its sides through which pass the section uniting bolts hereinafter referred to. Through the limbs A A are made transverse brush openings A which are produced by casting or otherwise forming transverse tubes in the limbs open at both ends as shown. The outer ends of said brush openings are closed by caps or covers a as shown.

Each section B consists of two vertical water legs 13 connected at top byatubular limb 13 below which is another limb B and below this (aboutcenter of legs B) is another'limb B which latter is, as shown, deeper than either of the other limbs so as to have the most water surface in that part of the section exposed to the fiercest heat. The limbs B may also be connected at bottom by a transverse limb B The limbs 13 B may be directly connected at center by a vertical hollow tube B and limbs B ,B ,bya similar tube B By this means a most thorough circulation of wateris provided, and a large water heating surface exposed to the heated products of combustion.

Through each limb B B B are formed brush openings b similar to those in section A and formed relatively thereto so that when a section or sections 13 are set up with sections A, the brush openings correspond in the severalsections, and form direct passages longitudinally through the boiler. Access to the brush openings in limbs B is had through door a of section A.

The section C is constructed like sections B with but one difference, which is, that instead of having supports for a grate as do sections B, it has an additional transverse limb O which ousts the grate bar and forms a bridge wall or back or fire chamber 1 as shown in Fig. 2. Like parts and features of sections B and C are similarly lettered.

The grate sections D, E, are constructed with legs and limbs like sections B,but in the meeting faces of sections D, E, which are always to be placed together, is formed the coal reservoir or feeder, half in each section. The opposed faces of the sections D, E, as shown in Figs. 3-and 4 have a curved shallow channel'D' E respectively formed in them. The front and back walls 01, e, of this channel extend between limbs B B and B B and are hollow as shown, the lower end of the channel terminating at the lower edge and centrally of limb'B, and at the upper end of the channel terminating at the side of the section and at end of limb B The walls (Z, c, also form part of the walls of the limbs 13, B B which are narrowed by said channel. The top and bottom or opposite side walls (1 e 01 c of this channel in the respective sections are so formed that when the sections D, E, are put together, a close continuous passage or fuel reservoir or feeder is produced between said sections as shown. The upper end of said reservoir is closed bya door D in the side of the complete boiler as shown. This construction enables the reservoir to be more readily filled than if it were on top of the boiler. The brush openings may extend through the front and back walls of the reservoir section if desired.

A damper E is located in the upper part of the reservoir and can be adjusted by a damper rod E as indicated in the drawings, so that before the door can be opened the damper rod has to be thrown back which opens the damper inside and allows the gas which has accumulated in the top of the coal to pass off into the flue, which otherwise would ignite and explode on opening the door. The rear section B corresponds in contour wlth the other sections and has an opening F for the escape of the products of combustionnear its top about opposite the fiues between limbs B B, then it has another opening F below the level of limb B closed by a suitable door through which access can be had to the fire chamber, and below this another opening F closed by a suitable door through which access can be had to the ash pit. The section is hollow and water can circulate therethrough substantially as in the front section. It may also be formed with brush openings if desired.

As shown in Fig. 2 a second fire chamber 2 is formed between section 0 and rear section F by the intermediate sections B, D,E, B,and access is had thereto through opening F in the rear section, and to the ash pit thereunder through opening F It will be noticed that the limbs of the intermediate sections are somewhat oval shaped, being wider at top so that when the sections are assembled together the limbs touch at the top thus forming closed transverse spaces or pockets 3 in the top of the fire chamber, and in the longitudinal flues 4, 5, formed between the series of limbs B, B and B B as shown. These pockets serve to trap the heat, but it is not confined therein, simply retarded, as the openings Z), I), form short connecting fines between the pockets so that the heat circulates up into the pockets and then along through openings b between the pockets to the ends of the flue as indicated by the tailless arrows in Fig. 2, while the heavier currents proceed through the main lines as indicated by the ordinary arrows in said figure. By this inter-circulation between the pockets the heat is induced to ascend thereinto and clogging thereof by deposits of dust and soot is retarded and the limbs and pockets are subject'to both direct and radiant heat, but if openings 19 were omitted and the pockets closed at top, only radiant heat would enter therein.

The sections have lateral perforated ears G on their sides through which pass bolts 9, g, uniting adjoining sections as indicated in the drawings. The bolts may pass through the side flanges of the front section and through ICO the rear section as indicated in the drawings. It will be seen that by this fastening any number of the sectionscmay be united in any order desired. The several sections are formed on their opposed faces respectively, near their outer edges with grooves and tongues as indicated at H, H, Fig. 2 so that a. close joint can be made between the sections from the outside. Lateral transverse recesses l, I, are made in the opposed faces of adjoining sections, and when the sections are secured together these recesses form-brush openings in the side of the boiler through which access can be had to the pockets above the fire chamher for cleansing them. These openings are closed by suitable doors L which maybe secured to frames L bolted on the sections as indicated in the drawings.

I, I, designate water pipes extending 2o transversely through the grate supporting sections, and lying just beneath and in contact with the grate and forming part thereof. In practice I propose tomount the grate pieces on these pipes, but this particular feature ,25 forms the subject matter of another applicatlon for patent filed-by me on the'9th day of March, 1893, Serial No. 465,297, and is therefore not herein specifically claimed. Each pipe I is preferably connected at one end by a suitable joint D higher than the grate to the section by which it is supported, and at the otherendto theopposite side of the sect1on, or it may be connected by a pipe t to the front or rear section as shown in Figs. 1 and 2 which is below the grate, By this means a more direct and powerful circulation of water through the pipes is produced, and the temperature of the grate is reduced and utilized toraise the temperature of the water.

'Each section isconnected at bottom to a drum J by suitable couplings j, and at top to a drum K by couplings is. If desired each section, or

anyset of sections, may be directly connected to aradiator, so-that different and independcut water circuits are established from and to the boiler through difierent or independent holler sections, and those sections subjected to greatest heat made to serve radiators farthest from the boiler. It will be of course obvious that sections 0, D, E, may be omitted when it is desired to make only a surface burning boiler. Or that section 0 may be omitted, or sections 1), E, transposed to the central portion of the boiler when it is desired to have a self feeding boiler, and that the length and capacity of the boiler may be governed by the number ofsections used in it.

It will be seen that each and-every section extends from the top down to the very bottom of boiler, forming as it does, asectional base,

which feature is new and very essential, as it often happens after a boiler has been set up,

it 1s found too small, or for some reason it is necessary to increase the size, which in my boiler can be'done by simply removing the front or back section and-adding as man more as may be necessary.

Having described ,my invention, what I claim as new, and desire to secure by Letters Patent thereon, is.. V a

1. In a sectional boiler, the combination Withthefront, rear and intermediate water holding sections, of a series of independent water-circulating pipes extending between fire-chamber and ash pit and connected by one end to an intermediate section, and by the other end to the front or rear section, sub stantially as set forth.
