SPECIFICATION forming part of Letters Patent No. 598,686, dated February 8, 1898. Application filed lune 23, 1897. Serial No. 641,900r (No model.)

To all whom it may concern:

Be it known that I, WINAND WM. J ToUssAINr, of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements .in Boilers; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in steam-boilers, and particularly in upright boilers.

utilize the heat in its passage from the nrebox to the chimney.

Another object of the invention is to simplify the construction of the boiler.

Another object of the invention is to so construct a boiler having a return-iire-tube system that the tubes may be more readily cleaned than as heretofore constructed. A

Another object of the invention is to improve the connections between the direct and the return tubes and the securing devices for such connections. A

The invention consists in the combined rebox and feed-water heater and the Hue-connecting section mounted thereon, in combination with the boiler-section mounted on the flue-section and having direct tubes located above the fire-box and return-tubes connecting with the hue-section.

The invention also consists in the tubular connections between the direct tubes and the return-tubes and in the means for securing such connections.

The invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described, and pointed out in the claims.

Figure l represents a front elevation of the improved boiler, partially in vertical section. Fig. 2 represents a top plan view of the same with the dome removed. Fig. 3 representsa plan View of the Hue-section. Fig. 4 represents an enlarged detail View of a portion of one of the tubes shown in relation to its con necting-elbow.

Similar numbers of reference designate corresponding parts throughout.

In the drawings, represents the base or ash-pit, which may be of any usual construction, being furnished with a door through which ashes may be removed. At the upper portion of the ash-pit is mounted a grate 6, forming the lowerportion of the fire-box. The fire-box is mounted on the upper end of the ash-pit and consists of an annular waterchamber 7, boxed between its walls around the opening 'for the fire-door 8. This waterchamber is provided with the usual inlet-pipe,

as 9, and with the outlet 10, connecting with the shell of the boiler. The water passing through this chamber of the fire-box is raised The object of the invention is to more fully` in temperature before entering the boiler.

On the combined fire-box and feed-water heaterismounted the flue-section 11, annular in shape, and having the partition l2 in its front portion and the partition 13 extending from its rear inner wall into the flue connection 14. Openings are formed in the outerwall of this section for the purpose of entering cleaning-Scrapers, doors, as 15, being supplied for closing these openings.

The boiler proper is mounted on the fluesection and comprises a shell 16, having the lower tube-plate 17 and the upper tube-plate 18, in which the tubes are secured, and the dome 19. On the tube-plate 18 is axially secured the bolt 20, furnished with the nut 21. In the tube-plates are secured the double system of tubesnamely, the direct tubes 22, disposed above the fire-box, and the returntubes 23 near the peripheries of said plates and connecting at their lower ends with the fine-section. The directand the return tubes are secured in the tube-plates in any usual manner. At their upper ends they are connected in pairs by means of the elbow connections 24, which have cup-shaped ends 25 fitting over the upper ends of the tubes 22 and IOO It will be noticed that both the boiler and the flue sections are larger indiameter thanthe interior ot' the tire-box. This allows the location of a large body of water in heating proximity to the fire-box. The Hue-section, being heated from radiation from the tire-box, will impart some of its heat to the water in the boiler.

The gases from the fire-box pass up through the direct tubes, then through the elbows 24, and down the return-tubes to the flue-section,

whence they pass around under the boiler to 'flue-sectionand comprising the plates 17'and V'18, a suitable shell, the tubes 22 and 23 se-1 cured in said plates and disposedasdescribed, 1 and aseries of elbowsfor connectingthe .up-v per ends of thetubes in pairs, and releasable` means for securing the elbows.

2. In a boiler, the combinationwith-theiirebox havingV the annular water-chamber 7, and@ the :flue section 11 mounted thereon, of a, boiler-section Vmounted on 4 the flue section and comprising the shell 16 havingthe'tube-E plates and disposed above the fire-box, and

the tubes 23secured in said plates and disposed above the flue-section.

3. In aboiler, the combination with the fireboX comprising an annular water-chamber, and a flue-section mounted thereon, of a boiler mounted on the flue-section and having a series of direct vertical tubes disposed above the lire-box, a series of return-tubes disposed above the flue-section and connecting therewith, and removable connections between the upper ends of each pair of tubes.

4. In aboiler, the combination with a shell having upper and lower tube-plates, and direct and return tubes secured in said plate, ot' a series of elbows removably seated at the upper ends of the tubes and connecting them in pairs, a spider having arms bearing on the several elbows, and means for securing the spider.

'5. The combination with the fire-box having the annular water-chamber, and the annular flue-section 11 mounted thereon and having the partitions 12 and 13 and the iiue connection 14, of the boiler-section mounted on the flue-section and comprising the shell 16 having ,the plates 17 and 18, the plate 18 having the bolt 2O with the nut 2l, the tubes 22 IVINAND WM.
