SPECIFICATION forming part of Letters Patent No. 379,975,-dated March 27, 1888 Application filed J uly 18, 1887. Serial No. 244,667. (No model.) i
To all whom it may concern:
Be it known that 1, DOCTOR F. MORGAN, a citizen of the United States, and a resident of the'city of Akron, in the county of Summit and State of Ohio, have invented a new and useful Improvement in Sectional Steam-Boilers, of which the following is a specification.
My invention has relation to improvements in cast-iron sectional boilers for heating purposes. Y
The objects of my invention are to increase the heating capacity of the boiler by placing the magazine outside of the sections and utilizing the part usually occupied by the magazine for heating, to'pro-videfacilities forcleaning the heating-surfaces from soot and ashes, and by a peculiar form of fire-pot section limit the area of the burning fuel and secure its more perfect combustion.
My invention consistsin the devices illustrated in the accompanying drawings, as hereinafter described and claimed.
In the accompanying drawings, Figure 1 is aside elevation of a complete boiler embodying my invention; Fig. 2, a vertical central section of the same; Fig: 3, a plan of the same; Fig. 4, an inverted plan of the top section or steam-dome; Fig. 5, a plan of one of the water-sections between the dome and fire-pot; Fig. 6, a side elevation of two of the same; Fig. 7, a view of cleaning-tube G, hereinafter referred to, which is interposed between the sections; Fig. 8,.a door for the tube G, with partitions hereinafterexplained Fig. 9, acrosssection of one of the radial arms of. the sections E, and Fig. 10a plan of -thefire-pot section.
Referring to the drawings, A is a hollow base, which forms the ash-pit, supports the grate a, is provided with doors a aflfor removing ashes and reaching the grate, respectively, and has an annular flange, 0, about its top, on which the boiler-case G rests. Upon this base is the fire-pot section B, which consists of a deep hollow ring having in its upper face water ports 0 and curved outwardly turned notches f, which register, respectively, with the water-ports e and flues f of the next upper section. Through this section on opposite sides, and vertically coincident with two of the notches f, are two openings, h, which pass obliquely downward toward the center of the grate, at each of which points the part of the section which constitutes the lower face of the opening extends in the same line inward for a short distance beyond the inner line of said sectionv and thence recedes outward,-'as.
shown in Figs. 2 and 10.
By this construction the fuel from the magazines, hereinafter described, is delivered near the center ofthe grate, which tends to retain the fire at that point, and the receding faces of the section prevent the grate becoming choked nected by hollow spokes, heart-shaped in crosssection,'as shown in Fig. 9, through which ring smoke-fines f pass-and into which water- 1 ports center at regular intervals and register with the dues and. ports of adjacent sections. The hubs E are of less depth vertically than the outer ring, so that hubs of adjacent sections do not touch; buta space is left between them, through which the products of combusgion pass, thereby increasing their heating-surace.
The spokes differ in number with the flues and ports, so that in building up the boiler the spokes of adjacent sections may alternate vertically.
In the upper and lower face of each ring E, across one of the smoke-flues, is asemi-elliptical notch, 9, so arranged that notches of adjacent sectionsshall register and form an opening by which'the inner heating-surfaces of the sections may be reached and cleaned. Opposite these openings are similar openings in the outer case, 0, in each of which is a tube, G, Fig. 7, which extends to the inside of the ring of the section E and has slots in its upper and lower faces coincident with the smoke-fines.
The end of each tube G is closed by a door, I, from the inside of which projects a rod bearing two plates, 12 i, which fit the inside of the tube G and close it on each side of the smokeflue f, thereby preventing communication through the tube between the smoke-flue and the center of the sections E, or the space between them and the case 0.
The steam-dome D consists of a hollow section with a concave base and convex top supported by its outer lower edge on the top section, E, provided with water-ports e which project down and meet and register with the ports e of the next lower section, a direct-draft flue, F, and a flange, about its outer upper edge, to hold'the upper edge of the case G. The case 0 between the flanges c c incloses the boiler, and has near its top an uptake-flue, F, with which the direct-draft flue F unites, in which latter is a damper, F.
On opposite sides of the boiler are two magazines, H H, which enter the openings in the section B, and thence extend upward along the case O, their upper ends being closed with doors.
In operation the magazines are charged with fuel, which descends by gravitation onto the grate. When the fire is first started, the damper F is open and a direct draft is produced inside of the outer rings of the sections E and out through the flue F; but as the boiler becomes heated this damper is closed and the products of combustion pass up inside of the outer rings of the sections E until they reach the dome D, thence down through the smoke flues f, and again upward between the case Oand sections 7 E to the uptake-flue F.
I claim 1. In a boiler of the class designated, the combination, with a fire'pot section, as B, having side openings, as It, thelower faces of which incline down toward the center and project beyond the inner line of the section, of magazines, as H, which unite with said openings and extend upward outside the boiler, substan-- tially as shown, and for the purpose specified.
2. The combination, in a boiler of theclass designated, of the grate a, the water-section 0 B, having side openings, h, with lower faces which project beyond the inner line of said section, the magazines H, united with said openings, and sections E, resting on said section B, all constructed and arranged substan- 5 tially as shown, and for the purpose specified.
3. The combination, in a boiler of the kind designated, of a series of water-sections, each consisting of a hollow ring provided with water-ports and smoke-fines, and a hollow closed hub less in vertical depth than said ring and united therewith by hollow spokes, substantially as shown, and for the purpose specified.
4. In a boiler of the kind specified, the combination, with the sections E, having notches g, and the case 0, having openings opposite said notches, of the tube G, door I, and plates 6 i, all constructed and arranged substantially as shown, and for the purpose specified.
In testimony thatIclaim the foregoingI have hereunto set my hand.
DOCTOR F. MORGAN.
