General Description.

In constructing the generator or boiler, I make it up of a series of cast-metal sections, each section being cast in a single piece and so constructed as to be a complete generator of itself, and the sections being so connected as to communicate with `each other, and each section is provided with a pipe for the disterior sections; and Gand D being the interior 0r intermediate sections. The front section A is provided with a re-door or opening, O, for fuel, and the rear section B is .provided with an exit opening, F, for the discharge of the products ofr combustion. These Asections are .all of cast metal of a single piece formed by castingon cores, and may be of the forms repre. sented in the drawing. The internal sections C D are precisely alike with the possible exception of the length of pipe for discharging the steam therefrom. The flat faces of the sections facing the other sections are surrounded by a raised rim extending to the bottom of the water leg, as seen at a, so that when the sections are placed in position a series of chambers, E, are formed between the water and steam space of one section and the water and steam space of the next section. This series of' sectional -generators constitutes a single generator when united by the screwbolts b, the sections communicating with each other at the top and bottoni by large openings e, through which these bolts b extend. The capacity of the generator thus constructed is regulated to adapt it to the size of the building to be warmed, and other circumstances of the case, by the `insertion of the proper number of intermediate sections, each of which adds water and steam-space, andA heating surface complete in itself, and gives an additional chamber, E. These chambers E being directly over the tire receive the heat rising therefrom, ,l

the I'ull ei'ect of and being out of the draught, the caloric is imparted to the sectional generators. In this construction the hen-t rises into a series of chambers without outlet, in-

stead of being'. carried by a current through tlues. Each section of vided at the top with a pipe, p, to receive the supplementary steam-chamber or radiator which is to be placed upon it.

In the .construction of the generator, by

making` it up of' a series of sections, as described, the disadvantage heretofore experienced in the construction of castiron boilers in the constructions adopted Aprevious to my invention has. been found in the danger oi rupture arising from unequal expansion of the inner and outer surfaces. This is altogether obviated by the construction here described,

same degree. This is altogether owing to the sectional construction by which the generator is made up," as in enlarging the capacity of the generator additional internal sections are inserted, the whole surface of which, with the exception of anarrow edge, is internal surface. The chambers E', which' are of the character of a caZ-de-sac, extend nupward above the water-line a b to the top of the steam-space, and this heats the entire surface ofthe top of each section. Herein these chambers differ essentially from any other character of generator. The sectional character of the generator, besides its adaptability to the end in View, is particularly advantageous from-the facility it gives for constructing generators of various capacities, the ease with which any portion may be repaired, and the facility of changing a generator of small capacity into one of larger.

i It is moreover cheaper ,ofv construction than any generator in use previous to my invention. P is oneof the supplementary steanrchambers The great diiicultyinvolved.

' since there is comparatively but little exterior surface to the generator; and that being in intiniate contact with what may be termed the internal surface, it is lheated to nearly the or radiators designed to radiate the necessary heat for warming the building intothe air to be warmed. This radiatorv P is made up of any number of sections, G, which may be required, three being the number shown though additional sections may be interposed between the outside sections and the middle section," if necessary, for the work t0 be performed. These sections G are each cast entire in a single piece upon cores in the same wayas the sections of the generator, and have projecting openings at the top and bottom, as shown, to form communication between the sections, and to separate them from eachother so as to leave space between therefor the circulation of the air to be warmed,`and,to forni channels therefor.

'The sides and edges, or in other words, both the broadest and narrowest sides of these sectionsrare made fiat forthe purposes of giving Aa greater amount of radiating surface in pro' portion to thev space occupied by the section,

and the internal capacity thereof, and aiding Va proximate surface in more perfectly heating fthe air, which purposes these flattened surfaces accomplish more perfectly than they ar'e A accprnplished by the cylindricalV surfaces of round iron. pipes. y

that the air-channels formed between the edges or narrowest sides of the sections G of the radiator P,are rectangular-that is to say, the flattened surfaces of the L narrowest sides of these sections face each other and give a direct radiation toward each other-Q which has a tendency to throw the heat into or at least toward the" middle of the current, as the column of' air ascends in the channel formed between the sections.

extendingthrough openings i, as shown in Fig. 5 and securing any desired number'of the sections together. One of the sections G of the chamber P, has a short pipe, p', extending downward from an opening into it to connect it to one of the pipesp of the generator, and

`form a communication between the chamber V P and-one of the sections of the generator, for the upward passage of the steam to supply the radiator, and the return to the generator of the water of condensation formed in the chamber P by the radiation of heat therefrom. A simple lvalve, V, with a rod, r, operatedfrom the outside, shown -in Figs. 2 and 5, serve to close the communication between the generator and the supplementary steamchambers, when desired. p

The manner of arranging these supplementary steam-chambers or radiators P above the generator, will depend on the locality and the circumstances of each' individual case. Thus, for example it will be seen by an inspection of Fig. |2 o the drawing, thatthree of the pipes p extending upward from the generator,

are all quite short, 'and two of them of the same length and the third one nearly so, which will bring the radiators P, when placed thereon, down near the generator, as shown in Figs. l and 2,. and alongsidefof each= other, while the other of these .pipes p is represented as being extended upward an indefinite length-or, in

other words, extended up higher than the three short'ones above mentioned-and broken oi, which would necessarily bring the radiator to be placed upon it into a higher position than that occupied by the radiator, shown in Figs. Land 2. t

vThe broad attened sides of the radiators P are excellent and direct radiatorsot heat, and when placed side by side, in accordance with the provision for the reception of most of them shown in the drawing as above stated,

they form large additions to the air channels formed between the sections G of each radiator, as above described, and the flat surfaces in like manner radiating directly toward each other, operate as heretofore stated, to throw the heat into .the middle of the channel so formed.

make no claim to horizontal cylindrical boilers coupled together as in use previous to my application for the original patent. Neither do I claim water legs below the main waterchamber of steam-boilers, as lsuchdii'er from my invention. Nor do l claim the formation of vertical flues in boilers.
