My invention 'relatesto new and useful improvementsin. sectional water heaters of 'that'gtype wherein a'plurality of independently formed sections are used either as a hot .Watertheater QrJsteam boiler. v

"The object of the inventionis to provide a novel construction of furnace that is es} peciallyadapted forburning oil, and wherein a series offlues are provided that extend through'the'length of the furnace so that an increased surfacetarea of the boiler will beexposedto"thefiame and products of com 'bustionfrom the fuel in a mannerto better extractthe' heat therefrom.

Affurther feature ofthe invention is to first pass the'fire through the upper sections of. thefurnac e,.an'd then down through its low-er.portions'wherei the water is naturally "coolest, and finally discharging the smoke outfrom the lower portion after the heathas; practically .all been extracted there "from. *By'this arrangement, the products of combustion, as they passfrom the combustion chamber, are exposed to'theupperpart of the boiler wherethe water is naturally the hottest, and then when cooler passes down through the lower portion where .thereturn incomingwater is naturally cooler.

Afurther object of my invention is to design a furnace which ismore oriless elastic, that is to say, one which readily lends itself to;the construction of boilers of different sizes and heating capacity, in-which a suit ablenuniber of intermediate sections-may be employed in away to forma longer or shorter boiler.

The :essential and characteristic features ofthe zinventionlare obviously susceptible of modification, 'the illustration shown in theaccompanying drawings being a preferred embodiment of thefinventiom as will be better understood from the following description wherein .references' made to the accompanying drawings of which .Fig. .lshows a perspective view -of my improved furnace, .as .it will appear when enclosed. by .asuitable .sheetmetal casing;

Fig. 7 showsafurther sectionalplanview through the lower portion of the. assembled units taken on2line.77 of Fig.2; and 7 Fig. 8 shows a detailed sectional .viewillustrating one of the sleeve connections employed in coupling the sectionstogether.

Referring first to 'Fig. ,4: of the drawings wherein is illustrated five c esmetal -sections, as used in the construction of a'boiler of specific capacity, are separately illustrated, it will be observedthat thefront section A and the rear section'B are different and that the intermediate sections C,.of which but three are shown,are alike in: construction though different from either oftheend sections. This obviously makes it practicalito employ a greater or. lessennumber of. the intermediate sections to form'a boiler. of greater orlesser capacity.

-Each-of1these sections formsrin itselfa water containing unit, and when assembled in series and secured together in the manneril- 9o lustrated in Fig. .2, formsa common water chamber 10 byreason of the nipples-connecting the upper andlower portionsof the several sections. Theseassembled sections form a central longitudinalcombustion chamber and associated fiues, service or feed pipe outlets 11, return inlets 12,.tapped holes l3for the attachment of an altitude-.gaugelt, and other tapped holes 15 for the attachment of try-cocks l6 and additional holes 17' for a 100 gauge glass 18, all of which are more or less employed in furnaces of this eneral type. The tapped hole 19 is for the attachment of an aquastat which is used as a safety device for both hot water and steam heating. 20 represents an opening for application of a stack control, not shown, and 21 represents a further hole which serves as an outlet through which the boiler may be emptied. If the boiler is used as steam boiler, it would require a safety valve and other accessories common to that class of boiler, but which I have omitted from the drawings.

It will also be obvious that the assembler unit, as shown in 2, may be covered in any preferred manner, and with any preferred material such as a preliminary coating of plastic or sheet asbestos that may or may not be covered with a sheet metal casing 22, as illustrated in Fig. 1.

Referring first to the general consti ction of the heater, as shown in Figs. 1, 2 and 4, and formed of the several conne t d sections, it will be noted that 23 represents the main combustion chamber which may or may not be lined with fire brick, not shown. The front end of the combustion chamber is enclosed with a closure frame on which is hung a door 2?. A gun type or rotary form of oil burner 26, that may be of any preferred make, is positioned in a hole 2'? of the frame and projected into the combustion chamber in the usual manner.

The several lines which will next be referred to, and which for the most partextend through different portions of the boiler, are produced by forming openings through and in the several sections, which are located so as to properly register one with another when the sections are assembled in a way to form a continuous passage or flue from the combustion chamber backward and forward and vertically to the smoke outlet which is situated in the rear portion of the furnace.

Referring first to the fi nt section A, it will be seen that it is provided with a central opening 28 therethrough, which like similar openings 28 in the other sections, e;=: cept the rear section B. serves to form the combustion chamber. The said rear section is, however, provided with pocket 29, Figs. 4, 5 and 6, that is of a size and position to register with the opening 28 in the adjacent section, and thus serves to form the closed rear end portion of the combustion. chamber.

The front section A. as well as t l e three intermediate (l-C. are provided with a central open ng 30 tlierethro 93h immediately above the combustion chanper 28 and adjacent the communicat n upper side openings 3131, which openi u, like the combustion chamber openings, are similarly located and of like sizes and proportions so as to register one with the other when the sections assembled, and whereby a central upper longitudinal flue 32 is formed that extends through each of the sections AC C-C and into a pocket 33 of the rear section B, the forward end of the said flue 32 bein open into the forward end of the com bustion chamber through a vertical opening 84, see Figs. 4 and 5, and whereby the products of combustion from the combustion chamber flow up into the central longitudinal flue 32 and back into the pocket where it returns and comes forward, see arrow Fig. 3, into the longitudinal flues 3535. The front end of said lines, as well as the other openings through the front section A, being closed by the metal casing 22 and doors hung thereon, as shown in F 1.

Each of the adjacent side faces of the several sections are provided with vertical concaved recesses on either side of the combustion chan'iber openings which, like the said openings and fines are proportioned and positioned to register with each other, see Fig. 6 when the sections are assembled, and for the purpose of forming a series of vertical lines 36 which extend down on either side of the combustion chamber from the before mentioned upper longitudina flues 35 and connect with the lower outer longitudinal flues 3'? that are formed by the openings 38 in the lower corner portions of the several sections. The two openings 38 through the front sec tion A, see 4 and 7, are relatively wider than the openings 38 through the intermediate sections so as to form a return into flue 89 from the longitudinal flue 37 formed by openings 40 through the intermediate sections C and rear section These openings in the last mentioned section B deflected inward to form a united smoke outlet or nipple 41 central of and the lower rear portion of the furnace.

Each of the vertical lines is provide with a clean-out opening 42 through each portion of the adjoining sections, which openings are normally closed by doors 43, see Fig. 1. The upper flues 32 and 35 are provided with clean-out doors 44 while the lower lines 37 and 39 are also provided wi h clean-out doors 45. The connecting openings to insure a circulation of water through all the sections are preferably formed by a series of aligned holes 46 through both the central top portion of the furnace and the lower central portion, the customary form of nipples 47 being employed to insure prop-er watertight connection as Jetwcen the sections. The sections may also be secured together in the usual way by tierods 48, two of which extend across the top of the sections and engace holes in flanges of t. 0 front and rear sections while the lower rods are preferably located in the flues 39 and have their end portions engaged with the end sections, one end of the rods being threaded and provided with a nut whereby sectlons may be drawn together.

It is to be noted that in the formation of larger number of fines that extend longitudinally through the furnace than 1s customarily found in cast metal types of boilers, but has I arranged the same so that the Jroducts or combustion first pass and repass through the upper portion of the furnace above the combustlon chamber and are then carried down ber to longitudinal lines in the bottom portion of the furnace which. again serve to carry the products of combustion forward and backward through the boiler.

It is also a feature of the design of ap-' plicants boiler that all walls of the sections, which are exposed on the one side to the heat or products of combustion of the boiler, also serve as a wall for water in the furnace in a way to quicker consume all the heat from the smoke before it is discharged into the chimney and thereby more efficiently heat the water.
