JUNCTION-PIECE FORSTEAM-BOILERS.
SPECIFICATION forming part of Letters Application filed January 23, [888.
Patent Ive, 381,039, dated April 10,1888- Serial Ifl'o.26l,638. (No model.) 7 I To aZZ whom "it may concern.-
Be it known that I, GEORGE S. STRONG, a citizen of the United States, and a resident of Improvements in Junction-Pieces for Steam- Boilers, of which the following is a specifica= tion. e I
My i'nventionconsists of certain improve ments in theconstruction of the steam-boilers other end of each junction-piece which unites with the fire-boxes or fire-box shell flares out into two united segments of tubes.
The junction-pieces, according to my for-- mer inventions, were tobe made of riveted plates, but such a construction, besides being more or less expensive, has the disadvantage that it is difficult to get all the joints perfectly tight to avoid leakage. To remove this diffi? time to reduce the cost of manufacture of the boilers and increase their efliciency, I draw, press, or stamp the junction-pieces each from a single seamless sheet of,metal, as Iwill now- In the accompanying drawings, Figure 1 is a diagram plan of the blank from which the junction-pieces for the fire boxes and combustion-chamber is made. Figs. 2, 3, 4, 5,6, and 7 are sectional diagrams showing the successive steps in the drawing, pressing, or stamping operations, Fig."3 being a section at right angles to Fig. 2,while Fig. 5 is a section at right angles to Fig. 4, and Fig. 7 is a section face view of the partially-formed blank in the to be applied. "Figs. 1 to 9 are corresponding views of the junction-pieces for uniting the fire box shell and barrel of the boiler.
part of the boiler in skeleton. Fig. '11 is a 1- v UNITED seeeee F CE;-
faceview of the finished junction pie celready 1.. Fig. 10 is a longitudinal vertical'section of partial sectional plan, and Fig. 12 isa trans 7 verse section through the fire box shell.
Inthe three latter figures, A A are the two tubular fire-boxes, which are corrugated,.as
set forthin my prevous patents, and A" is the fire-box shell,which consists of two tubesyor rather segments of tubes or barrelsmnited'and connected by a plate orcross-braces, a,,at their points of junction.
B is the barrel of the boiler, within which are the combustion-chamber O and fire-tubes D. I' The fire-boxes are united to the combustionchamber by the j unction-piece E, and the firebox shell is united to the barrel by,th efjunc{ .tionpiece F. Each of these junction-pieces has at one end the form of a single tubeand at e the other the form ofunited segments of tubes,
and I form each junction-piece of'a single seamless sheet of metalin' the manner whichil will now describe. I To make the junction-piece E, I first cut out of a sheet of metal of theprop'erathick. ness a blank of'the form shown in Fig. 1that is, of adiamond or lozenge shaped. ou t1ine with rounded corners and a central opening, p. The blank is put in a press, which has a lower die, 1, of the shape shown in Figs. 2 and 3, an outer clamping-ring, 2, and two upper dies, 3 and 4, one adapted to pass withinand through the other. When the sheet Fig. 1
has been placed on the lower die, 1, it isfirmly I clamped thereto around its margin by the'ring 2. e The die 3 is now operated to press or draw the sheet down into the lower die,with' the. effect of bringing the sheet to the dish'shape shown in Figs. 4 and 5. The inner die, 4,is now brought into action to press ordraw the center I ofthe sheet down to the shape shown in Figs. 2 and 3, after which thelower edge of the flaring tube or dish thus formed is flanged," shown in Figs. 6 and 7. The upper or largerflanged end of this flaring tubeis of the'lo'zengeor diamond outline with rounded'corners shown in Fig. 8, and like the original sheet, Fig. 1, while the opposite smaller end, similarly flanged, is of the circular form shown in Fig.
8, of the proper size to correspond with the flanged end of the combustion chamber, to which it is to be united by these flanges. The larger end of this flaring tube or junction-piece has to have its shape further modified to make it a double tube to be united to the flanged ends of the fire-boxes. For this purposeI introduce into the opposite bowlshaped ends 0 of the dish filling-pieces or cores in the form of hemispheres, as indicated by dotted lines in Figs. 6 and 8. I then apply to the outside of the dish at the points y 1 suitable side dies, by which those edges of the dish are pressed inward to about the parallel lines m, Fig. 7, and then shaped dies having the contour which those parts of the junction-piece are to finally take are applied to the opposite sides of the dish at the same points to press those sides farther inward to the points indicated by the dotted lines n n, Fig. 7, with the result of giving to the junction-piece its final shape (shown in Figs. 9, 10, and 11) as applied to the fire-boxes and combustion-chamber.
The operation of drawing, pressing, or stamping up thejunction-piece F is substantially similar to that for thejunction-piece E, dies being used similar to those shown in Figs. 2 and 3, but of course modified in size and contour according to requirements.
A blank of sheet metal of the form shown in Fig. 1 is placed in the press and clamped to the lower die around its margin by means of a suitable ring, 2, Figs. 2 and 3*.
blank is then brought by means of the dies to the dish shape shown in Figs. 4 and 5" at a suitable number of successive heats or operations, and then by meansof an inner die, similar to the die 4, Figs. 2 and 3, the center of the dish is drawn down, as shown in Figs. 2", 3 6, and 7, the partially-formed blank then The having the shape shown in the plan or face view, Fig. 8. A
The hemispherical fillingpieces are placed in the bowl-shaped ends of the dish, as de scribed with reference to Figs. 6 and 8, and by means of suitable outer dies the edges y of the dish are pressed inward first to the parallel positions indicated by the dotted lines m in Fig. 7 and then to the final positions indicated by the dotted lines n in Fig. 7, and shown more clearly-in the front view of the finishedjunction-piece, Fig. 9.
I do not claim in this application the welded fire-box shell shown in the drawings, as that forms the subject of a separate application for a patent filed by me January 23, 1888, Serial No. 261,637.
I claim as my inventionl A seamlessjunction-piece for boilers, one end of the junction-piece having the form of a single tube and the other end united segments of tubes.v
2. A seamless junction -piece for the fireboxes and combustionchamber of a boiler,one end of the junction-piece being flanged and having the form of a single tube, while the other end is flanged and has the form of united segments of tubes.
3. A seamless junction piece for boilers, drawn up of a single sheet of metal, one end of thejunction-piece having the form of a single tube and the other the form of'united segments of tubes.
In testimony whereofI have signed my name to this specification in the presence of two'subscribing witnesses.
GEO. S. STRONG.
