WILLIAM J. RANTON, OF SYRAOUSE, NEW YORK.
STEAM-G EN ERATOR.
SPECIFICATION forming part of Letters Patent No. 484,339, dated October 11, 1892.
Application filed March 9, 1 892.
To all whom z5 may concern:
Be it known that I, VILLIAM J. RANTON, of Syracuse, in the county of Onondaga, in the State of New York, have invented certain new and useful Improvements in Steam-Generators, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
My invention relates to improvements in steam-generators particularly adapted to be supported in a suitable casing of brick or other material, and has for its object the production of a simple and effective device which is economically constructed and isv extremely durable and efficient in use.
To this end it consists, essentially, in a water-containing shell, a fire-flue supported Within the water-containing shell, and water-circulating tubes extending through the fire-flue, and in the detail, construction, and arrangement of the parts, all as hereinafter more particularly described, and pointed out in the claims.
In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate; corresponding parts in al] the Views.
Figure l is alongitudinal'section o f my 1inpro'ved generator, shown as 1n operative position within a suitable casing. Fig. 2 is a front elevation of the detached generator and Fig. 3 is a longitudinal horizontal sectional view taken on line 3 3, Fig. 2, a portion of the nre-flue being shown in elevation and a portion broken away.
A represents the Water-containing shell, which is of any desirable form, size, and constructiombeing here illustrated as composed of an outer tube A', circular in cross-section, and formed of the plates a a', secured together attheir adjacent ends by rivets or other suitable means a2 and the heads a3 and a4, arranged at the opposite extremities of the tube A. The water-containing shell is at Fig. l shown as operatively mounted within a casing B, which is of suitable form and construction and is composed of any desirable material. The casing B is provided with a combustion-chamber b, arranged beneath the forward end of the steam-generator and with the rearwardlyextending fire-passage b',

having the upturned extremity b2, suitably closed at its top by a Wall b3.
C represents afire-flue arranged within the Water-containing shell A with its opposite extremities secured by rivets c to the opposite heads a3 a4, which are preferably formed with inwardly-extending integral iianges 0.5, encircling the ends of the {ire-flue. By forming the heads a3a4 withinWardly-extending flanges and securing the opposite ends of the fire-flue thereto the joints between said parts are protected by the Water, and all leakage is prevented by calking said joints from the inside, wliich operation is readily permitted by manholes above and below the lire-due, as presently described.
As readily seen in the drawings, the front head CL3 of the water-containing shell A is somewhat separated from the front plate B of the casing B, for forming a draft-chamber B2, and in front of said head is the upwardlyextending draft-pipe B3. It will thus be evident that, as indicated by the arrows at Fig. l, the gases and products of combustion generated and highly heated within the combustion-chamber pass through the passage o and its upturned end b2, and then through the fireflue into the draft-chamber B2, and through and out the draft-pipe B3. The fire-flue is sufficiently large to permit combustion of the gases within the same instead of checking the combustion, as is usually the case when heated products of combustion are passed from a large chamber through small tubes. Moreover, this combustion-flue is of such form and construction as to present to the heatedv products of combustion a great amount of surface and cause the absorption of the heat and generation of a great amount of steam.
As best seen at Fig. 2, the fire-flue is formed of two plates C and C2, secured together at their adjacent ends, is arranged centrally within the water-containing tube A, and is of greater width than thickness in order that its extremities may closely approximate the adjacent surfaces of said tube, and thereby heat as great a quantity of water as possible. The upper and lower walls C3 and C4 of the fireue, which are formed by the central portion of the central plates C and C2, are preferably hat, in order to facilitate the securement to said plates C and C2 of water-circulating ICO water above the tire-fine and to prevent any accumulation of sediment thereupon. l
In generators of considerable length I prefer to support the central portion of the lireiiue by braces F, having one end 'secured at f each to the fire-fine and the other at. f to the inner face of the tube A. I also prefer to tie the central portion of the separate heads to the tube A by means of braces G, having one end secured at g to the head and the other at g to the adjacent outer plate a a.
Instead of using inclined braces G, as described, I may use a rod G', extending lengthwise of the watercontaining shell A', with its opposite extremities secured to the opposite heads.
For the purpose of permitting replacement of one of the water-containing tubes or cleaning of the boiler, I provide in one of the heads of the water-containing shell, as the head a3, manholes H, above and below the fire-flue C. The head is formed with the inwardly-extending integral iiange h. A plate h is arranged within the water-containing shell and is drawn firmly against the adjacent edge of the flange h by a bolt h2 passed through a cross-bar h3 on the opposite side of the head as and provided with an adj usting-nut h4. The removal and replacement of the flues D is rendered practical by forming the flue C of less thickness and the iiues D of less length than the vertical distance between the iiat upper and lower walls C3 C4 of the liuc and the adjacent portions ofthe tube A', as clearly seen at Figs. 1 and 2.
In constructing my generator the tube of the water-containing shell is rolled and formed in the usual manner and provided with a single head. The fire-flue is then suitably formed and secured to the opposite head and forced lengthwise within the outer tube A, whereupon the head securedl to the tire-tine is then secured to the outer tube of the watercontaining shell.
AThe iiues are easily repaired or replaced, and owing to the peculiar construction and arrangement of the fire-flue, the water-circulating tubes, and the manholes but a minimum amount of sediment is deposited upon the upper side of the ire-liue, and this may be readily removed at will.
The operation of my invention will be readily understood upon reference to the specification aud the accompanying drawings, and
Moreover, this c ir-` culation tends very effectively to agitate the it will be particularly noted that the same is simple, practical, efficient, and durable, and is economically manufactured and readily repaired, and that the peculiar construction of the tire-tine and water-circulating tubes permits combustion of the heated gases within said tire-flue and insures the absorption of the heat therefrom, thus greatly increasing the eiiiciency of the generator.
Having thus fully described my invention, what I claim as new, and desire to secure by LettersPatent, isp f 1. In a steam-generator, the combination of `a combustion-chamber and a firepassage leading from the combustion chamber, an outer water-containing shell above saidchamber and passage, a head at one extremity of the shell, formed with a central opening connected to the fire-passage, a head formed with an opening aligned with the former opening, said head being secured to said shell at a point considerably within its outer edge, whereby the shell extends beyond the latter head, forming iu front of the latter head a draft-chamber, which is partially incased by the projecting portion of the shell, and a ireflue having its opposite extremities registered with said openings for conducting the products of combustion from the tire-passage to the draft-chamber, said tire-flue being composed of a pair of plates having their central portions disposed in substantially-parallel planes and their adjacent longitudinal sides rounded toward each other with their longitudinal edges lapped one upon the other, and rivets for securing said edges together, substantially as set forth.
2. In a steam-generator, the combination of an outer water-containing shell provided near its opposite extremities with heads formed with openings in their central portions, said shell being extended beyond the front head to form a smoke-box, a fire-Hue having its extremities mounted in said openings and com- IOO posed of a pair of plates having their central portions disposed in substantiallyparallel planes and their adjacent longitudinal sides rounded toward each other with their longitudinal edges lapped one upon the other, rivets for securing said edges together, and tubes extending through the fire-fine and formed of less length than the vertical distance between the ends of said tubes and the adjacent portions of the water-containing shell, whereby the tubes may be removed without removal of the re-liue, substantially as and for the purpose described.
3. In a steam-generator, the combination of a combustion-chamber and a fire-passage leading from thecombustion-chamber,an outer water-containing shell above said chamber, and a passage provided at its opposite extremities with heads formed with openings in their central portions, a tire-flue having its extremities mounted in said openings and composed of a pair of plates having their central portions substantially parallel and their adjacent longitudinalV edges lapped one upon the other, rivets for securing said edges together, tubes extending through the re-iue with their ends secured to the central portions of the plates composing the lire-flue, and a draft-chamber formed by extending the outer shell beyond the front head for receiving the products of combustion discharged from the fire-flue, substantially as set forth.
4. In a steam-generator, the combination of an outer water-containing shell provided near its opposite extremities with heads having oval openings in their central portions, said shell being extended beyond the front head to form a smoke-box, an oval tire-flue having its extremities mounted in said openings, the front head having manholes above and below said tire-flue and opening into said smoke-box,
plates for closing said manholes, means for holding the plates temporarily in place, and upright tubes extending through the fire-flue and of less length than the Vertical distance between their ends and the adjacent portions of the outer shell, whereby said tubes may be removed from the re-iiue and through the manholes, substantially as and for the purpose set forth.
In testimony whereof I have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 26th day of February, 1892.
