Application filed March 8, 1912. Serial No. 682,483.
ess for making boilers by which the various parts of the boiler structure are secured together so as tomake them a single unitary structure, and in addition so treating the parts thus Secured together that all internal strains are relieved.
More specifically, my invention consists in taking the various parts of a steel boiler and securing them together by means of the oxy-acetylene'blowpipe, so that the adjoining portions of the various parts flow together, thus uniting the parts into a single homogeneous structure, in which the metal is continuous through the structure, after which the completed structure is heated sufficiently, preferably to redness, so that the molecules of the structure may readily assume positions entirely relievin any internal strains that may have existed after the fusing operation and manufacturing of the tubes. The structure thus heated is carefully cooled so that there is no chance of introducin unequal strains in the structure by the coollng operation.
As is'well known in the art, standard steel tubing such as is generally available for making boiler structures of difl'erent kinds is somewhat tempered or hardened, as a result of its manufacture, and, furthermore, the hardness is apt to be somewhat different at different points in the tubes. By my process the joints between adjoining parts of a boiler structure in which such tubes are employed are made omparatively soft by the fusing of the parts together, and I find it is sequent application of heat 'to it will not produce unequal strains tending to break downor warp the structure.
My invention is not limited to the construction of boilers of any particular type, but may be employed equally Well w1th either fire-tube or water-tube boilers, and it may also be applied either to boilers of the so-called flash type or to those inwhich a water level is employed.
The several drawings illustrating my invention are as follows:
Figure 1 shows a boiler in which water tubes are employed.
Fig. 2 shows a boiler in which fire tubes are employed, the boiler being of the waterlevel type.
Fig. 3 shows a boiler in which a water tube is employed, the boiler being of the flash tyge.
. imilar numerals refer to similar parts throughout the several views.
As shown in Fig. 1, the Water tubes 1 extend between two vertical headers 2 and 3, the ends of the tubes 1 being secured to the headers 2 and 3 by fusion by means of the oxy-acetylene blowpipe, so that the joints resultin a continuous metal structure from one part to' another, as indicated at 4. A water header 5 is employed to supply water to the boiler and a steam header 6 serves to collect and remove from the boiler the steam generated.
In the structure shown in Fig. 2, the tubes 7 are secured in the boiler heads 8 and 9 by fusion by means of the oxy-acetylen'e flame, so that the metal is continuous from the tubes to the heads, and the head 8 is secured into the shell 10 by the same means. In Fig. 2, the boiler shown has its head 9 formed integrally with the shell 10, so that no operation is necessary for securing these parts together.
In the modified construction shown in Fig. 3, the flash coils 11 and 12 are secured together, as indicated at 13, by fusion by means of the oxy-acetylene flame, and the ends of the coils are also securedto the water header 14 and the steam header 15 in a similar way, as a result of which a single homogeneous structure results.
The particular boiler constructions shown in Figs- 1, 2 and 3 do not constitute a part of the present invention but are shownherein to indicate the adaptability of my process of making boilers toboilers of various types.
While my invention consists broadly in making a boiler structure by fusing the parts together so that they constitute a single homogeneous structure and then heating the resulting structure sufficiently so that unequal internal strains are eliminated, it will be understood that my invention is particu larly applicable to steel boiler structures,
since parts made of steel are more apt to have internal strains resulting from their construction than are parts made of softer metal. By the term steel, as used; in-this connection, I mean to include all forms of steel or iron, whether used in combination with other substances or not, which may be used in forming boiler structures of any type desired.
, What I claim is:
1. The process of forming a boiler which consists in placing edge to edge a plurality of thin-walled steel parts formingpart of a closed vessel, then fusin the adjacent edges only and flowing the i used metal at said edges together to unite the adjacent edges,
then heating the structure resulting the parts so joined, to substantially a red heat and then slowly cooling to relieve the internal stresses in the metal.
2. The process of forming a plurality of tubes of difierent lengths and diameters into boiler sections, which consists in placing the tubes at the points where joints are to be made, with their edges together, then heating adjacent edges only to the point of fusion and flowing the metal of the edges together, then allowing the fused metal to cool to a point where the entire structure isselfsupporting, then heating-the entire structure to substantially red heat to relieve in.-
ternal stresses, and then slowly cooling.
'3. The process of making boilers which from 'cooling the same. 1 7. The process of constructing a boiler which process consists in welding together a suitable cooperating parts to form a substantially closed steam container by melting the adjoining parts until they flow together, heating the resulting structure sufficiently to equalize its internal strains, and slowly cooling the heated structure. v
5. The process oftreating a steel boiler constructed of parts of different lengths or thickness united by molecular .union of said parts, which consists in heating said entire boiler to substantially red heat and thereafter slowly coolin the same. 6. The process 0 formingand treating a steel boiler which-process consists .in j oinlng' together constituent arts of a boiler to form a hollow substantial y closed structure, then heating said entire boiler structure to substa'ntially red heat and thereafter slowly plurality of tubes of diiferent lengths to and between a pair of risers communicating with all of said tubes to form a substantially closed boiler structure, and then heatin said,
entire boiler structure to a red heat an then slowly cooling same.
In 'tnesswh'ereof, I hereunto subscribe my name'this 29th day of February, A. D. 1912' WILLIAM H. WINSLOW,
Witnesses,
ALBnri'r C. BELL, ALBIN C. AHLBERG.
