SPECIFICATION forming part of Letters Patent No. 524,878, dated August 21 1 894. Application filed Jane 2,1893.' sentito. 476.404. (No model.)

To all whom t may coicern:

De it known that I, AMASA WoRTHrrIGToN, acitlzen of the United States, and a resident of the city of Brooklyn, county of Kings, and State of New York, have invented certain new and usefullrnprovements in Boiler-Settings, ot' which the following is a specification.

My invention, while applicable to the Vsettir g of boilers generally, is designed more especially for usein `connection with sectional steam boilers of the cross tubular class, as represented, for instance, in Letters Patent of the United States, No. 424,528, which were grantedlto me April 1, 1890, to which reference may be had. Y

In the setting of boilers, ,as heretofore practiced, it has been the custom to inclose the boiler and form the tire-box or furnace in a b rlck-work structure, which extended up the sides of these parts, and, in most instances,

over thetop thereof, its dimensions being such as to not only form the nre-box or furnace and envelop the boiler, but likewise permit of the proper circulation of heated gases and the products of combustion through and around the parts to be heated. This'particular mode of setting, while efficient with boilers of the cylindrical and other equivalent` forms, has been found objectionable in practice when used in connection with boilersof the sectional water` tube class, principally because of the fact4 that the removal of the tubes, as is frequently required in consequence of their rupture and for other causes, necessitates the tearing away and demolition of the portions ofthe brick-work structure at the points where the tube is to be removed, and its replacement after the insertion of a new tube in place of the one withdrawn. Further than this, the great amount of space required, when the masonry structure is employed, is also objectionable, especially when applied in connection with a sectional cross tubular boiler, since, in order to withdraw a tube from the latter, some considerable space 'is required at the sidethereof, amounting to nearly the length of the tube withdrawn, which space is ynot always convenient to provide without making the boiler room of an inordinate size.

The object of my invention is, to overcome these defects,fand to provide a setting for boilers, which, while occupying but little more space thanwhat is actually demanded to rel ceive the boiler itself, shall provide means for the ready removal of the tubes when required, without necessitating in any way the tearing down or demolition of any part of the setting, while at the same time reducing the a costof the setting to theniinimum. I

To ,these ends, the invention consists in a boiler setting composed of independent panels or sections, preferablythough not necessarilyu of metal, united to form a structurain which fl. is a front elevatiotiwof a boiler of a `well known form, withboiler setting, constructed in accordance with my invention, applied in connection therewith; Fig.2, a side view of such parts looking from the rightin Fig. l;

l as will 7'@ ing drawings,

Fig. 3, a transverse sectional detail of the side l casings; Fig. 4, a similartransverse sectional detail of a slightly modified form thereof, and

Fig. 5, a transverse sectionalelevation of a boiler, of a slightly modified construction, with a setting, made in accordance with my invention, applied in connection therewith.

In all the gures, like letters of reference are employed to designate corresponding parts.

A A indicate a plurality of series of water tubes, the alternate series of which are in-t clined in opposite directions, and BB B2 B3 the headers in which the ends of the respective tubes are secured.

Located above the wat-er tubes A A', is a steam and water drum, C, to `which are connected by tubes, a. a, the upper ends of the o headers B B3, while below such water tubes, and connected with the steam and water drum C, by the tubes bb, are the water drums D D, which are similarly connected tothe lower ends of the headers B B2 by the tubes ce. Thesewater drums D D are likewise connected by the tubes d d, and,`like the steam` and water drum C, extend throughout the en-` tire length of the boiler.

ICO

B3, in line with both the water tubes A A and the tubes a a, are apertures to permit f the ready removal of the tubes when required, and these apertures are closed at all other tlmes by covers, e e, and bolts, ff, as shown. The parts, as thus far described, form no part of my presentinvention, but are here referred to for` the purpose of illustration, and are or may be the same as the corresponding parts shown and described in the Letters Patent above mentioned, to which reference may rial which lmay be made in plate or sheetv form, may be employed, and these are so shaped as to make them conform in their outline to the general crosssection ofthe boiler in connection with which they are to he used,

and to the ends of the Afire-box or furnace of: When em-` which they are to form a part.

ployed in connection with a cross-tubular boilerof the class shown in the drawings, I ypreferably, .though not necessarily, construct 'theiil in open skeleton form, with the inner or central portions removed, and provide drums (D D, which rest therein, whereby to aord a firm support for the boiler in the boiler setting. ,l

In the example of the invention shown in the drawings wherein is employed the open ference of the steam and water drum C,

ing across such openings beneath the drum,

tions that are not occupied by the ends of otherwise secured at their ends to the-'endframes EXE, are provided on their upper edges with recesses, t', i, of the proper con-V V ,f ""ferxnation to suit them to the under semi-circumference of said steam and water drum, and, with the portions of the end-frames above, surround the `ends of such drum 'wheretheyprotrudetherethrough. The'ends of the steam and'water drum thus protruding are, or may be, covered by suitable covers or caps, C C', `which are secured yto the endframes and panels by rivets or'otherwise, as shown.

VThe panels I I will, in some instances, be

tymade of a sizeto completely cover the central openings in the end-frames'E E. I prefer however, in practice, to provide one or Formed'in the side of the headers B B B2" E E indicate the vend-frames of the boiler of these end-frames, 'cast'metah is deemed them with suitable openings in their bases for the reception of the ends of the Water` skeletonconstruetion, the upper edgesof they centralopenings in the end-frames E E are made to conform to the upper semi-circum-- which protrudes therethrough; While extend-l `so as to cover those parts of their upper porsaiddrum, are panels, I, which, riveted or both of them with a door, K, whereby to aord access to Vthe interior of the boiler sett-ing at the end or ends thereof when required to remove soot and other accumulations -from the exterior of the water tubes and for other purposes. When this last mentioned construction is adopted, the panel I, instead of being made of the proper width to coverthe entire central opening, will be made of va Width to cover only the upper portion thereof, and the doorK hinged to the lower edge of the same by hinges, lo lo. As thus arranged, the door K may be made of a width to cover the portion of the central open ing in .the end-frame E, not covered by the panel I. I find it convenient, however, to make it of'a width somewhat narrower than what is required for'thatpurpose, and to employ a second panel, L, which, secured to the end-frame E by rivets or otherwise, 'and extending across -under the door K, so as to cover the lower portions ofthe central opening in such end-frame, is provided at its upper edge with buttons or other fastening devices, Z Z, for engagement with the lower edge of the door, whereby to hold such door tightly closed,when access to the interior of-theboiler setting at "that place is not'desired.

When ein ployedin connection with a boiler setting that admits of the firing vor stoking at the'end or ends thereof, as in the construction illustrated in-Figs. land 2, the'end-frames E E (one or both), in additionito'being provided with'openings for the reception-of the ends of the water drums D D, or other'suppo'rt- -in g devices for the boiler, will be likewise-provided with'openings to the fire-box or furnace and to the. ash-pit, which will be lequipped with suitable doors, "M and N,'respectively.

vIn vthose constructions, 'in which these endframes E E, are madefsolid, without any-central opening therethrough, the lopenings -to the'irebox or furnace and to the ash-pit will be both formed therein,vand the doors M and N will be hinged to their outer side. When, on the other hand, the end-frames are made in open skeleton form, then only thef opening to the ash-pit will 4be made rthrough such frame, E, and the opening "to the vfire-boxer furnace will be made through the panel L, the doors M- and N in that case being hinged respectively to the end frame and panel,'as shown, but this arrangement, it is obvious, may be modified in various ways, and bothopenings, either formed through. "the endframes or through the 'panel yif desired. Again, when the firing or stoking i's effected along'the side of the boiler, asshown, for instance, in Fig. 5, the openingsto both the fire-box or furnace and to the :eljsQh-pit,y with their accompanying doors, are omit-ted from the end-frames E E, and such end-frames, however constructed otherwise,`lef t unprovided with those parts.

Secured to the end-frames E E,1andv extending across from one to theother are the sidecasings O O, by means of which the'sdes and 'IIO topy ofthe setting are formed. casings may be constructed in various ways and from a diversity of materials. I ,prefer however to make them in plate form, either wi th or without an appropriate lining, and to apply them to the setting .in'such a manner as to leave a door or doors along one or both sides thereof, above the lire-box or furnace whereby to afford easy access to the interior of the setting for removal or cleaning of such tubes or for making other repairs to the boiler as occasion vmay demand.

In the embodimentof the invention illus- 1o and p2 constitute thelxed and immovable thereto by rivets, s, or otherwise, whereby to impart tothe same the necessary degree of stilness and strength, and,in addition thereto, to serve as limitingwalls for the heat resisting material q, which is arranged on that side of the panels between such ribs or angle-irons as in a shallow pan. v

In the construction of the panel@ the ribs or angle-irons r are secured inward from the edges thereof some little distance, whereby to permit of the sheet-metal body projecting slightly beyond the same, as is also the case with the edges of the doors p3, and p4,see Fig. 3, while with the 'other panels p `and p2, such ribs or angle-irons rare secured to their 4respective panel with their depending portions lush with the extreme edges thereof. As thus constructed, the panel p, which is or may be provided with a suitable thimble, t, or other appliance by means of which to conneet with the chimney or'up-take, is secured to the top of the boiler setting by rivets or other equivalent means co-operating with the end frames E E, with the projecting edges of its sheet? metal body extending downward over the upper edges of the panels p', which are similarly secured to the end-frames on opposite sides of the setting. By this means, as will be seen, provision is made not only for closing the cracks that would be formed between the edges of the panelsp and p', but also for securing such panels lirmly together, which latter may be done by passing bolts or rivets down through the projecting edges of the panel p and through the edges of the panels p', as illustrated at u.

The panels p2 are in like manner secured to the end-frames E E on opposite sides of the setting, at or near its bottom, by bolts or rivets, o, while the panels p8 and p4, constituting the doors, are hinged respectively to the pau- 'rhs side,

are provided ther than this,

els p and p2, by hinges, w, with the projecting edges of their sheet-metal bodies overlapu.ping the adjoining edges of such latter panels, whereby to cover up the cracks between them when the doors are closed. The doors, being thus hinged to the fixed parts of the setting, may be held closed by any appropriate hasping or fastening devices. I preferhowever to provide their adjoining edges with projections or abutments w', and to employ bolts, 102, for that. purpose which, passing through suitable orifices in such projections or abutments, are provided withvnuts on their ends by meansof which the adjoining edges of the doors may be drawnk together when required and firmly held in that position with the projecting edges of their sheet-metal backs overlapping.

' When the firing or stoking is to be eected from the end or ends of the boiler, the panel p2 will be made imperforate throughout, as shown in Figs. l and 2, but when such tiring or stoking is to be effected along the side or sides of the boiler, as shown in Fig. 5, then such panels will be made somewhat wider, and one or both of them will be provided with suitable openings into the fire-box or furnace and into the ash-pit, which openings will be equipped with appropriate doors, M N, as is the case when the tiring or stoking is done at the ends thereof. As thus constructed and arranged, the panels or doors p4 will be hinged to their upper edges, all as is shown in Fig. 5.

For lining the various panelsconstituting the side-casings of the settingf,any of the Well known heat resisting materials may be employed. I prefer however to make use of cement, magnesia, or tire-felt, which, having beenV treated as is usual in such cases, is firmly packed against the inner sides of the panels inthe cavities formed by their sheet-metalbacks and the ribs or angle-irons r secured thereto. In most instances, the lining will be held in the cavity of the panel by its own adhesion or by passing bolts therethrough, and through the sheet-metal backs, but if desired sheet-metal strips, g, may be arranged on its inner side, and be tied to the sheet-metal backs or to the ribs or angle-irons 'r by bolts passing through them and through such strips, as illustrated in Fig. 4, or by other appropriate means.

The setting, being constructed as aboveset forth, occupies but little more space than the boiler itself, and being built up from material of plate or sheet form permits of the location of doors in its sides and ends, whereby free access to the interior of the settingis affoi-ded for the removal of tubes, repairs or otherwise, without necessitating the demolition or destruction of any part thereof. Fur the setting while applying the heat to the boiler in the most efficient and economical manner, at the same time presents a construction which is exceedingly cheap,and more ornamental and sightly than those heretofore in` use.

IOO

greater than it is practicable or desirable to make the panels of the side-casings, open skeleton frames similar to the end-frames E may be interposed between such end-frames and the several panels and doors constitut lng the side-casngs spliced thereon.

Although in the foregoing I have described the best means contemplated by vme forearflo rying my invention yinto practice, I Wish it distinctly understood that I do not limit myself strictly thereto, as it is ,obvious that I may modify the same in various ways without departing from the spirit thereof.

Haylng now described my invention and certain of the ways in which itis or may be carrled into eiect, what I claim as new, and desire to secure by Letters Patent of4 the United States, is i 1. The combination, with the end-frames of a boiler setting constructed in plate form, and provided with openings and doors above the fire-box or furnace, of side-casings composed of independent sheets or panels sey cured 'to said end-frames, and provided with openings and doors therein, substantially as described.

2. The combination, with the end-frames of a boiler setting, and a boiler, of openings 3o 1and doors in said end-frames above the {iret Mrt .f ox or independent sheets or panels secured to said end frames, and .provided with openings and doors also above the fire-box or furnace, substantially as described.

3. The combination,

with the end-frames furnace, and side-casings composed of my hand this 22d day of May,

When the length of the boiler required is offa boiler setting and a cross tubular boiler,

of side-casings composed of sheets or panels and provided with openings and doors inline "with the ends of the series of water tubes,

substantially as described. y

4. The combination, with a cross tubular boiler, and the end-frames of a boiler setting, provided with openings and doors opposite the series of water tubes, of side-casings composed of sheets or panels and provided with openings and doors in line with the ends of the series of water tubes, substantially as described. l

5. The combination, with the end-frames, and side-A casings of a boiler setting constructed in sheet or panel form, and secured to such end framesby bolts or rivets, of openings and doors to the fire-box or furnace and to the ash-pit, and other openings and doors in the side-casings above the fire-box or furnace, substantially as described.

6. The combination, with the end-frames and sidecasings of a boiler setting constructed in sheet or plate form, of openings and doors to the re-box or furnace and to the ash-pit, and other openings and doors in both the end-frames and side-casings above the {ire-box or furnace, substantially as described.

In testimony whereof I have hereunto set AMASA WORTHINGTON.
