BRONSON, F KEWANEE, ILLINOIS, ASSIGNOR TO XEWANEE BOILER COR- POIRATION, 0F XEWANEE, ILLINOIS, A COBPORA'IION- 0F DELAWARE BOILEB f l Application led October 85, 1929. `Serial No. 402,366.
-Thef presen-t invention concerns heaters, boilers and like or similar appliances, particularly those made of sheet-metal and aims to provide a structure of this general character having certain structural and manufacamount of welding is reduced to a minimum and the cost of production correspondingly lessened. f
Accordingly, the structural elements entering into the appliance as to their shapes, forms, locations, relation to other members, etc., are such that the boiler or heater may be produced or manufactured with the least amount of material, labor and expenditure of funds.
The manner in which such aims or purposes and others are attained may be understood by those skilled in this art from a consideration of a. preferred embodiment of the invention illustrated in the accompanying drawings, forming a lpart of this specification, and throughout the views of which likel reference numerals have been employed to designate the same parts.
In these drawings:
Figure 1 is a central, longitudinal, vertical section through the boiler;
Figure 2 is a front elevation of the boiler;
Figure 3 is a vertical cross-section through the boiler on line 3 3 of Figure 1;
'Figure 4 is a fragmentary, vertical .crosssection on line 4-4`of Figure 1; and
Figure 5 is a side elevation of the wrapper sheet which in part encloses the auxiliary combustion-chamber. I
Referring to the severalA figures of the drawings, it will be observed that the novel and improved sheet-metal boiler or heater 'p structure comprises a front, upright, metal plate 11 having a substantially semi-circular, top edge and parallel,v vertical edges, its lower, horizontal margin being provided with an inturned flange 12 for the greater portion of its ,length corresponding to the widthQofv the fire-box, the boiler including also a rearwall plate 13 of llike contour with a similar,
The main shell sheet 15d iswben'tv to harmonize with the shapes of the front and rear walls between which it fits and to the rear and front facesfowhich respectively it is suitably welded, the bottom, side edges of such plate havinginwardly-projecting flanges 16,
16 the ends of which are likewise welded to the flat faces of the front and back wall plates.
The fire-box or fuel-combustion chamber has a front Wall plate 17 with an arched, top edge and upright, parallel edges, the plate being of less width than the corresponding dimension of the boiler to provide for side water-legs in the latter with proper circulation therein.
A door opening 18 is provided inthe outer plate 11 and a corresponding, registering aperture 19 is present in the inner plate 17 the space between the two plates affording a front water-leg 23 sealed around the doorway by a ring composed of a bent plate 22 and its companion straight plate 21, both located between the outer and inner plates 11 and 17 and 'welded thereto and to one another. f
0f course, such doorway is supplied with the customary lire-door, but this has not been shown.
A water-leg 24 is present at the back of the ire-box20 and is formed between the outer, wall plate 13 and an inner, rectangular plate 25 spaced therefrom and having along its top border an outturned flange 26 welded to the inner surface of member 13, the flange 14 of the latter being welded to plate 25 along its bottom margin.
The crown-sheet or inner wall of the firebox or main combustion-chamber reaches from the inner face of element 17 to the inner surface of member 25 having its edges welded to each of these, such crown-sheet being bent to form a curved or arched crown-` sheet proper 27 and parallel, vertical sidewalls 28,28, the flanges 16, 16 of plate 15 10e-A lDIS Such plate 27, 28, 28 at its rear end is cut away aiongg,1 the lines 29, 3l to provide a top aperture oit substantial size to aidord communication with an upper, suplemental combustion-chamber 30 tormed y a duea sheet 32 whose lower, curved edge conforms to, overlies, and is welded to the outer surface oit the crown- sheet 27, 28, 28 and by a sheet having a wide, horizontal top 33, parallel, wide, side-walls 34., 34, and narrower, downIm wardly-extending, side- wall sections 35, 35.
The parts 33, 3d, Se; entend from plate 32 to plate i3 and have their edges welded to each and the extensions 35 have their front edges likewise welded to the Huesheet, and, where their lower ends continue down beyond the ends ot the flue-sheet, they overlap and lie flat against the outer suriface of the crown-sheet member 2?, 28, 28 and are welded to it, not only adjacent to the margins 29, 29 but also the full length of the borders e1, ai.
`W all i3 just above the rear waterLleg 2d and beneath the plate 33 has a doorway 36 therethrough fitted with a suitable door 37 giving convenient access to the interior oi the auxiliary combustion-chamber 30, to the flue-sheet and to its lines 38, 38 which connect also with the Jiront wall or header "il, longer tlues 39, 39 mounted in the iront and rear walls joining the iront connection il with the stach connection l2 as in the usual way.
The various parts are strengthened in the customaryrnanner by stays which are shown and the boiler is equipped with other ordinary ttings also illustrated, but none oit which require `lurtlier mention.,
The manner in which the members are shaped and combined to allow ease eeen-l oiny in welding1 should be observed and tention is also directed to the tact that the y opening or doorway 36 extends through only trein the `substance oi the invenu tion and without the sacrifice of any of its salient advantages.
ll claim:
l. 'ln a metal boiler, the combination oil outer, :iront and rear plates, an outer shell se cured to said plates, an inner rear plate spaced trom said outer rear plate orrninga water= space between them, a hottom ange on one ,iis
iside walls for the nre-box of the boiler, out away at the back portion of its top and welded to said inner-.rear plate, a flue-sheet weldedto said bent plate adj acent to the aperture formed by said cut-away section, and a bent sheet between and welded to said flue-sheet and said outer rear plate and also welded .to the ends ot said top Harige ot said inner rear plate and having narrower side down ward extensions welded to said flue-sheet. crown-sheet plate around the lower portion of its cut-away section and to the edges of said inner rear plate, said outer roar plate having an opening therethrough between said bent plate and Water-space affording; access to said due-sheet, and a closure for said opening.
2. ln a metal boiler, the combination of outer, front and rear plates, an outer metal shell secured to said plates, an inner rear plate spaced from said outer rear plate :torming` a water-space between them and having a flange around its top edge welded to said outer rear plate, the latter having a doorway therethrough above said Water-space I and angeg a door for said doorway, a bent plate forming a crown-sheet and inner sido-walls for the boiler re-box welded to said inner rear plate and cut away at its back top portion, a flue-plate welded to said crown-sheet plate, and a bent plate between and welded to said flue-plate and outer rear plate around said doorway and having1 narrower downward extensions welded to said flue-sheet, crownnsheet plate and to the opposite edges of said inner rear plate.
