superior utility.

Among other features my invention aims;

to do away with large piping and malleables in the downflow-pipes, water-legs, or. large manifolds to supply water to the uptakes and to provide a boiler of this class which may readily be erected and repaired and whereby increased efficiency may be secured.

My invention consists of the'construction, T co1nbination,and arrangement ofdeviceshere' inafter described and claimed, and illustrated in the accompanying drawings, in which- 1 Figure 1 is a front elevation of a sectional boiler embodying my invention, the inclosing} ease having its front removed. fFig. 2 is a longitudinal section. on the line 2 2,'Fig. 1.

tical tubes C. Thesetubes convey water from the dome down to the distributing-pipe B.

A isthe steam-pi peleadin g from the dome. 135 .is the water column, communicating, preferably, with the front leg of the distributing-pipe, the front: leg'extending downward,

as shown at B at the front of the boiler, and

providedwith'a valve, as shown at B.

B isgthe gage. 1 Blisth'e inflow-leg of the distributing-pipe, preferably located at. the rear of the boiler.

D is the grate; D, the co'mlnistion-cham- My inven t10n has for 1ts ob ect an improved sectional boiler of novel construction and of ceive acorresponding series of connectingpipes E and E, entering the dome on the two Theseholes extend at suitable intervals from end to end of the dome. j

F and F denote two series of lower manifolds, one series extending from each side of the distributing-pipe, as shown, at a down- 'ward incline,the manifolds of each series p referably located closely side by side and each manifold of each set. united to the distributing-pipe B by a connecting-nipple G, said nip "pleslGhaving right and left hand screw" threaded connections-with the corresponding manifold and withthe distributing-pipe, re-

ends,[as shown at 3, to engage corresponding threaded. orifices h in the upper manifolds Similar orifices 7t are formed also in the. upper side of the manifold, registering withthe orifices 7b. The lower ends of the pipes J are of the same diameter as the pipe and have a threaded engagement in orifices f of the lower manifolds.

It will be seenthat theupper'.manifold is constructed with ori [ices h audit of sufficient diameter to allow the lower ends of the pipes ICO J to be passed thercthrough, whereby the said pipes may readily be located and secured in place, the two ends being threaded into the corresponding upper and lower manifolds. The upper manifolds are provided with plugs 7L2, engaged in the upper side thereof to close the orifices h after the pipes J are in place. The outer extremities of the upper and lower manifolds are also provided with plugs 7L3, having a threaded engagement therewith, whereby the manifolds may readilyhe cleaned. The upper manifolds are connected with the pipes E and E, respectively, by series of pipes K, connecting-nipples K, intervening between the manifolds and the pipes K, unions or Ts K connecting the pipes K and nipples K. The pipes K are preferably arranged. in sets of two pipes each, each alternate set being raised above the adjacent sets of pipes to permit a ready engagement of the pipes with a wrench to engage the pipes in place. I prefer, also, to employ Y-shaped couplings (indicated at L) to unite two of the pipes K or a set of said pipes with a single pipe E or E, thereby diminishing the number of pipes entering the dome. The pipes K are set at an angle parallel with the manifolds. The pipes J and the pipes E and E 011 corresponding sides of the dome are also parallel, the pipes J on the two sides extending upward at divergent angles.

It is obvious that an upper and a corresponding lower manifold connected by the uptake-pipes J form a section connected to the distributing-pipe by the right and left threaded nipple G, while the section is connected to the unions K by the corresponding and similarly-constructed nipple K. It will be seen, therefore, that each section can readily be taken out if repairs are necessary by simply disconl'lecting the corresponding nipples G and K. Every section is thus independent of the other sections, so that each may contract and expand independently of the other. The sections may be removed either by making the top of the case D removable or by taking out the grate the sections may be taken out through the fire-door.

It will be obvious that the water entering the distributing-pipe B passes thence into the lower manifolds F and F and thence into the uptakes J. The location and arrangement of the sections in the combustion-chamber are such that the heat may pass about and around and between the uptakes and under and over the lower manifolds and about the steamdrum, as well as about the upper manifolds, and the pipes connecting the upper manifolds with the dome in a most effectual and therough manner.

The steam generated in the uptakes J passes into the dome, while any water in the pipes J willfall back into the base thereof and into the lower manifolds, the water being held therein. Vater of condensation in the steamdome will obviously flow down through the tubes ('3 into the distributing-pipe. The tubes J, connecting the top and bottom manifolds, are preferably steel tubes. All the threads in the top and bottom manifolds and on the tubes J are right-hand threads. The tubes, being smaller than the orifices h and h in the upper manifolds, may be readily passed therethrough, so that the threads on each end of said pipes or tubes may be screwed home at the same time by any suitable instrument, as an ordinary pipe-wrench. WVhen the individual sections have been thus put together, they are ready to be connected with the dome and with the water-distributing pipe in the manner above described. The lower manifolds, being connected closely together, form a solid crown-sheet over the fire by which the products of combustion are diverted and compelled to pass to either side of the sections, outward around the outer ends of the lower manifolds, then inward through the tubes J against and about the dome, thence upward through the pipes connecting the upper in anifolds with the dome, and thence up the smokestack D The upper manifolds are also placed close together, thereby preventing the products of combustion passing therethrough and forming a fine between the manifolds. The water-legs I3 and B form sedimentpockets and also support the boiler. They may be provided with any suitable fittings at the bottom for bolting down, as indicated at B". The casing may be constructed in any desired manner, preferably of sheet-steel and fire-felt, and may be bolted or secured to the upper manifolds in any suitable way.

I prefer 'to connect the pipes O with the water-distributing pipe, as illustrated more particularly in Fig. 10, employing a jam'nut 0 upon the pipes O,with an intervening packing-ring M, preferably made of soft metal. Vhen the nut is run forcibly down upon the packing-ring, the joint will be made steamtight. Below the adjacent ends of the pipes E E within the steam-dome I prefer also to locate a shield R, which may be secured intermediate its ends to the dome in any suitable manner, as by rivets at r, the shield extending downward in both directions a sufficient distance to direct the steam toward the lower portion of the dome, as shown more particularly in Fig. 8, the arrows showing the direction of the products of combustion.

The orifices in the pipe B to receive the nipples G are shown at G.

The steam-pipe A preferably ru us the whole length of the steam -dome therewithin, the same being shown broken off in Fig. 2 intermediate its ends in order to disclose other parts of the construction. The same is shown' in cross-section in Fig. 8 and is preferably provided with orifices (indicated at a) on the upper side thereof, suitably distributed for the entrance of steam thereinto.
