STEAM GENERATOR.
SPECIFICATION forming part of Letters Patent No. 813,270, dated March 3, 1885.
(No mrdel.)
T 0 all whom it may concern:
Be it known that 1, WILLIAM ZELLNER, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Steam-Generators, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which Figure l is a vertical longitudinal section, and Fig. 2 a transverse vertical section, of a fire-box embodying my improvements.
This invention relates to certain improvements in steam-generators for which Letters Patent of the United States were granted to me May 8, 1866, No. 54.654.
In my former Letters Patent referred to that portion of the boiler containing the heatingtubes extends backward into the firebox for the purpose of increasing the heatingsurface and distributing the heat therein, and such arrangement is included in my present invention, together with certain changes and additions in details of construction, which I will first proceed to describe, and subsequently to point out the novel features thereof in the claims.
In the drawings, A represents the shell of a boiler; B, the lire-box, and G the fire-tubes, that project about midway into the [ire-box and are secured to a depending tube-sheet, a, the same as referred to in my former Letters Patent.
To the lower end of the depending tubesheeta, I connect an inclosing-sheet, b, and extending at an obtuse angle therewith to the front water-leg of the fire-box, as shown in Fig. 1. In my former Letters Patent referred to the inclosing-sheet [2 extends at right angles to the tube-sheet and parallel with the lire-tubes, forming beneath it a fire-chamber rectangular in section, which in practice has a tendency to huddle the gases and deflectthe same horizontally toward the fire-door. Such construction in form also lacked a comparative degree of strength. The inclination given to the sheet b not only allows the gases to pass freely upward, but directs them to all parts of the crown-sheet and to fill the entire upper portion of the fire-box, as indicated by the arrows, Fig. 1. The inclined position of the sheet I) also acts to brace the respective parts to which it is joined and make room for the transverse re-ent'orcing bars d, without interfering with the fire-tubes. The re-enforcing bars cl are composed of parallel plates, between which crow-foot bolts are passed, that secure said plates together and to the sheet I). These bars are also shown, and have heretofore been applied, to the crown-sheet of the fire-box, but only secured thereto and at one side of the shell of the boiler. In the present invention Ihave extended the same entirely across and secured both ends to the boilershell, thereby bracing the latter. The sheet I) is given an easy bend at its junction with the depending tube-sheet a, so as to offer no obstruction to the passage of the gases and to avoid weakening in bending. The bars (1, above the fire-tn bes, are provided with curved diverging braces d which extend from them to the outer shell of the boiler. The strengthening-bars (1, attached to the top of the inclined sheet 1/, are provided with similar braces, 02 which extend from said bars cl to the sides of the inner shell of the boiler. These braces d d, with said bars (I d, greatly strengthen the said shells. The inner faces of this boiler are plane, and not spherical or curved. The inclined sheet I) will not operate to huddlethe products of combustion or cause them to converge, as it would it said inclined part were curved in cross-section. The air-inlets e are located below the lower end of said inclined sheet I).
I am aware that it is not new to extend firetubes into the combustion-chamber of a cylindrical boiler and provided with an inclined shell extending below them, the inner faces of the various parts of the boiler being curvilinear.
I am further aware that itis not new to provide the crown-sheet of a fire-box with strengthening-bars, which are fastened to said crown-sheet and to the shell or casing of the boiler. These constructions, therefore, I do not claim.
\Vhat I do claim, and desire to secure by Letters Patent, is-
1. In combination with the crown-sheet of a fire-box and the outer shell of the boiler, a series of strengthening-bars, d, attached both ICC to said crown-sheet and shell, and two or more 3. The tubes 0, fire-box B, and tube-sheet a, diverging braces, d d, attached to' said in combination with inclined sheet b, curved strengthening-bars at their inner ends and to at d, where it is joined to said tube-sheet, said boiler-shell at their outer ends, substansubstantially as set forth. 5 tiall y as and for the purpose set forth.
2. A series of fire-tubes, 0, extending into WILLIAM ZELLNER. the fire-box and provided with a plane inclined inclosing-sheet, b, in combination with WVitnesses: strengthening-bars d, arranged above said in- CHAS. W. FORBES, 1o clined sheet, and braces b, which connectsaid J. S. CALDWELL.
bars with said sheet, substantially as set forth.
