Application iiled May 22,1891. Serial No. 393,722. (No model.)
T @ZZ whom t may concern/.-
Be it known that I, GEORGE S. STRONG, of the city and county of New York, State of New York, have invented a certain new and useful Improved Boiler, o t which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to the construction of boilers, and especially the type of boilers known as locomotive-boilers, my object being to provide a boiler of great strength and durability, and which, among other advantageous features, can be shaped to embrace a lire-box having a very large grate area.
The nature of my improvements will be best understood as described'in connection with the drawings in which they are illustrated, and in which- Figure 1 is an end view of a locomotiveboiler having my improvements, partly shown in cross-section on the line 1 2 of Fig. 3 Fig. A2, a cross-sectional end view, the part to the right being taken on the section-line 3 4 of Fig. 3 and the part to the left on the sectionline 5 6 of Fig. 3. Fig. 3 is a longitudinal sectional elevation of the boiler, in which, however, certain details of construction are omitted on account of the small scale of the drawings, such details being shown in other gures. Fig. 4 is a view,on an enlarged scale, taken on the same sectional line as Fig. 3, but showing only a part of the boilershown in Fig. 3, but that part in more detail. Fig. 5 is a plan view, on an enlarged scale, taken on a section-line 11 12 of Fig. 3. Fig. 6 is a sectional view taken on the line 7 3 of Fig. 1; Fig. 7, a sectional view on the line 9 10 of Fig. 1, Fig. S illustrating a modification of 4ov the construction shown in Fig. 7. Fig. 9 is a section on the line 13 14 of Fig. 4; Fig. 10, a perspective view of the end of -the calkingpiece of the end M2. Fig. 11 isa cross-sectional view of the crown-sheet of the lire-box, 45 taken the part to the left on the line 15 16 and the part to the right on the line 17 18 of Fig. 13. Fig. 12 is across-sectional view showing a part of the crown-sheet on the line 19 2O of Fig. 11; Fig. 13, a similar view taken i 5o on the line 21 22 of Fig. 11; Fig. 14, a similar view taken on the line 23 2e of Fig. 11;
Fig. 15, a similar view taken on the line 25 26 of Fig. 11. Fig. lisacross-section through the side sheet of the fire-box, taken on the line 27 28 of Fig. 13; Fig. 17, a similar section taken on the line 29 30 of Fig. 18; Fig. 18, a view showing a part of the side sheet, taken on the section-line 31 32 of Fig. 16; and Fig. 19, a cross-sectionalview showing a modiiied forni of lire-box.
A'is the boiler; B, the top plate of whatin locomotive-boilers is called the wagon-top," B B', the side plates extending down from the wagon-top on each side of the fire-box.
C is thesteam-dome, which, as shown, extends upward froni the wagon-top, but which might oi' course be formed on the barrel of the boiler.
D is the fire-box; D', the grate; E, one of the lire-box doors; F, the tube-sheet extending from the end of the iire-box and through which pass the tubes G of the boiler.
H H, &c., is a series of braces bolted on each side of the wagon-top to angle-irons I, said angle-irons being riveted to the side of the wagon-top over the seams between the plates B and B which are greatly strengthened thereby, and being fastened to the bars I-I by the bolts I and I2.
J is the crown-sheet of the lire-box. It is made, preferably, of an arched cross-section and with deep transverse corrugations merged into outwardly-extending anges J at the sides, and upwardly-extending iianges J 2 and J 3 are formed at the ends of the kcrown-sheet., these flanges being in effect .continuations of the flanges J', as indicated at J,4 and J 5. The ange J2 is united with vthe end plate Lof the fire-box by means of an Adamson seam, of which M indicates the calking-piece interposed between the two plates secured together. plate L by a lap-joint, as shown. The front liange J 3 of the crown-sheet forms an Adamson seam with the end plate N,N indicating thecalking-piece between the flange and plate.
O O are the side plates of the fire-box.
The tube-sheet F is secured to the" These plates are corrugated to correspond IOO J of the crown-sheet, so that the two sheets can be united by an Adamson seam, the calking-piece of which is shown at M2. The side plates have also flan ges O extending out from their back ends, by which they are united to the plate L, forming an Adamson seam with said plate, the calking-piece M continuing between the flange O2 and the plate L. Corresponding flanges O3, formed on the front ends of the side plates, form an Adamson seam with the plate N. These end flanges Ozand O3 are in effect continuations of the flange O', uniting with it, as shown at O4 and O5. One (preferably the inner) set of corrugations or folds in the side plates is made flat, as shown at O, for a purpose to be hereinafter described, and the corrugations of the side plate merge at its bottom, so that the bottom edge of the plate O7 be straight and flat. This bottom edge lies along and is riveted to the mudring P. The plates L and N are also riveted to the mud-ring P, and the mud-ring is recessed in its corners, as shown at P', Figs. 5 and 2, this notch receiving the Adamson seam formed between the side plates of the fire-box and the two end plates thereof in the manner illustrated in the two figures above referred to, the portions of the flanges and calkingpiece which extend into the notch P being indicated by the letters o3, Z3, and m3, This plan of uniting the mud-ring and plates is one which insures great strength and stability of construction. The Hanging of the corrugated crown and side sheets of the lire-box forming the seams in the'man'ner described enables the parts to be unitedwith great firmness and strength and enables me to use Adamson seams, which are not likely to be burned out in all places where such burning would take place with lap-seams.
When the nre-box is flared out, as shown in Figs. l and 2, in order to make room for a large grate area, it is desirable that the top of the nre-box should be supported against the strains which tend to collapse it, and this support I provide in the manner I will now describe. Angle -irons Q, placed back to back, are riveted to the top or wagon-top of the boiler, so that their outwardly-extending flanges willbe in line with inward folds of the corrugated top sheet of the fire-box, and upon bolts Q', passed through the angle-irons Q and also through the bolt I of the angleiron I, which lies in the same plane with the angle-iron Q, I secure links R R R3, thelower ends of which are secured on pins or staybolts S S S, which pass through the sides of the inward fold and are riveted on the inside `of the crown-sheet, asl indicated at S. Preferably a pair of links are used in each case, one passing on each side of the tie-rod I-I, as shown in Fig. 4. The use of tie-rods extending from the top of the boiler to the top of the crown-sheet is, I am aware, not new with me; but the plan of securing these tie-rods which I have described and shown is novel in several respects and possesses, I believe, material advantages.
I have already mentioned the flattening of the portions O of the side sheets, and will now state that this is done to provide proper bearing and holding surfaces for a series of stays T, having end extensions which pass through holes in the side sheets ofthe boiler and fire-box and are riveted thereon, as indicated at T. By thus uniting the side sheets of the boiler and fire-box the strength of the corrugated side sheets is materially increased and a firm support provided for the corrugated crown-sheet which rests upon the side sheets.
It will be noticed that by the construction of my fire-box Adamson seams are brought against the other seams, bolts, or flanges, and that one flange J2, for instance, which constitutes a part of one Adamson seam, forms a continuation of the flange J, for instance, which forms a part of an Adamson seam intersecting the first one. WVhere such intersections occur I provide the calking-plate of the Adamson seam with a rivet-extension m', which is continued through the abutting plate and riveted thereon, as indicated at m2, Figsni and 9, and where flanges turn,\as at J4 and O4 in the figures referred to, I make the calking-piece with annular projections m m, which lit into the turn of the flange and against the abutting flange or plate. The strength, compactness, and closeness of the seam thus formed will be readily appreciated.
Referring now to the steamdome C ofthe boiler, I form the upper part of the dome of a dome-shaped piece U, which is drawn into shape by dies, much as a cartridge is drawn. To the edge of the piece Uis secured a flangering U', extending over the top sheet of the boiler, and another flange-ring U2 extends beneath the top of the boiler and alongside ot the upwardly-extending annular part of the ring U. The use of the flanged ring U2, which may be called the strengtheningpiece in the arrangement shown, materially strengthens the joint, making the union ofthe dome indeed a point of exceptional strength instead of, as is now commonly the case, a weak point in the boiler.
Having now described my invention,'what I claim as new, and desire to secure by Letters Patent, is-
