` "Beitknown` hat we; JOHN AMERICUS FAN' snAwE, of` Tottenhamyin the county of Mide dlesex-,iin` that `part of; the United Kingdom of Great Brilainfand =Ireland known as England,

o engineer, and JAMES ARCHIBALD JAQUEs, of

` the same'fplace, chemist, `have invented "new l Improvements lin i the Construction of. 'Steame Generators, (for :which Letters `Patent were granted inyGreatBritain bearingfdate the 31st `dayof October, 1861,) l` and we do .hereby del clare that "the following is a full and exact de- `scr-iption of our saidfinvention.A o Ofvur" invention of improvements in 1 the conl o o strnctionof steam-generators has for its object to 4construet steamegeneratcrsin., such a manner thatthey `,may be Lmade muchstronger: than heretofore. hewater-spaces andilues orlsmoke-passag re also so arranged and combined that uch `as possible of the caloric `contained he' heated gases-that are `evolvedfrom th gnited fuel may be absorbed by thewater coutainedpin the generator, so' that. a considerable economy of fuel may be effected.` J

" To this end thelgenerator is subdivided into several narrow waterLcompartments, between.

which fines of a convolute orserpentine form e are arranged, lsothat the heat may be absorbed l from `the gases as theypass from the lire-place through .the convolnte or serpentine ilues to the chimney. l 'lhelliues` or passages for the heated gases maybe formedof narrow widths of wroughtlorplateiron rolled up into a con- 4volute, or serpentine form, and when they are placed between thenarrow water-spaces (of which there maybe any convenient number,

- according f tothe size or capacity whichit is desired to give "to the boiler) the narrow waterspaces, with `the `Ieonvolute or serpentine o iinesor -passages between them, ,are rmly bolted together, `or aresecured in a suitable framing; or, `il' preferred, the plates a maybe o bulgedoutor corrugated at certain parts, so `that when `brought together they will form l passages orjspaces along which thegases from` the fire-place maybe conducted. By this means `algreatlyincreased `len th of line is obtained water to absorbtheheat 'froml the gases vas they pass from the fire t `the chimney. The fur- .TED

nace isiplacedeitherV below orl at the side of the generator, so, that the flamewand heated 'gases therefrom may beconducted with facility into the convolute or serpentine ilues, and l while traversing these lines will part with their caloric and will issue, 'at a greatlyreduced temperature, into a flue that iscornmon to all, and from whence they may bev conducted :dig rect to the chimney or passed through a pipe placed in the steam space above.l By adopt.- ing this` latter arrangement ithesteam in the` steam-space will-become superheated by the heat'givenoffrom the flue, andthe gases (reduced intemperatnre) will ultimatelyiescape into the atmosphere. spaces are constructed of such formand dimensions as to have a steamspaceat theirupper partsand this steam space may .be-madeto communicate withfa common steamfchamber, through which theexitilue of the furnace may be conducted, if desired; Y e

In the accompanying drawings, Figure 1,

Sheet I, is an end elevation of one of our improved steam generators. Fig. 2 isl a side elevationfof the same. AFig. 3, `Sheet 1I, is a longitudinal vertical section` of, the boiler. Fig. 4 isatransve'rse vertical section in the line 1 2 of Fig. 3, and Fig. 5 is a similar View taken inithe line 3 4 of Fig. 3. v

o The 'boiler is composed of a series of narrow compartments, A A A A, which are the water-spaces. These compartmentsare composed of side plates, f1/a a a 'a' a', and narrow rings b b b, which pass all round the compartments A, and are secured to the side plates, c a a'n, 'ny means of angle-iron c c and rivets, as seen in Figs. 3 and 5. 4

The side plates, ct a, are ,corrugated at the lower part at a a', so thatwhen two compartments A A are brought together, as shown in thedrawings, the corrugated parts will form a curved convolute or serpentine iiue or passage for the gases froml the furnace or rire-` place B to thecommon exit-flue C.. A central hole, D,is made through all the compartments, and through this hole is passed a solid or tubular tiered, d, provided with screw-nuts at one or'both ends, so that by screwing up the nuts on the tie-rod all the compartments A may be heldl tightly together.- The external spaces betweentheliolesor openings in the comparti .The narrow watery ments are lled up'by hollow rings e e, through which the tie-rod d passes, and the internal spaces round the tie-ro d are made good by other rings f f, which areperforated all round, so as to allow the-water from one compart ment A to ilow into the next, and so on throughout the series, in order that a proper circulation of water may be kept up through out the boiler.

If desired, the tie-rod d may be made tubular and branch tubes therefrom may be made to dip nearly to the bottom of each waterspace, so as to keep up a circulation of water in the lower parts of the compartments, and prevent the accumulation of sediment or solid matters which would otherwise form an iuerustation in the boiler, or, if desired, the boiler may be supplied with water through the tubu 'lar tie-rod.

The upper parts of the compartments A A, together with the intervening spaces E between the several compartments, are made to form one large Vwaterspace from end to end ofthe boiler, and common to all the compartments A by forming large circular openings in the sides of the latter, as shown in the sectional view, Figs. 4 and 5. The intervening spaces E between the compartments A are closed by 4means of wronght-iron rings h h, which'are secured to the sides a a of the water-spaces by means of angleirou and rivets and bolts i i,

instead of allowing the heated gases from the furnace to pass direct into the chimney, and from thence into the atmosphere, we conduct them along a return flue, which is placed in the steam-space above the boiler, in order to dry and superheat `the steam before it is aliowed to pass to the working-cylinder. When no additional steamchamber is employed, a

Steampipe, k, provided with suitable stop-l cocks, is adapted to the end plate of the boiler, as seen iu Figs. 3, 4, and 5. A safety-valve, l, is adapted to a steam-pipe fixed iu the end plate at the opposite end of the boiler.

When it is desiredto obtain access to the interior of the boiler, the tie-rod j may be loosened and the man`hole cover on one of the end plates removed. A man can then get inside and can remove the nuts of any of the compartments A, so that the latter may be taken out, if required, after removing the tie= rods d and j, i

What we claim as our invention, and desire to secure by Letters Patent of the United States of America, isf--` The constructing of steamboilers with a series of distinct narrow water, spaces or compartments combined together'side byside and having provided between them `convolute, curved, or serpentine lines or tire and gas passages, substantially as herein speciiied.

In witness whereof we, the said JOHN AMERIoUs FANSHAWE and JAMES Ancnr.
