MILTON W. HAZELTON, OF NEW YORK, N. Y., ASSIGNOR TO HIMSELF AND E. S. T. KENNEDY, OF SAME PLACE.

SECTlONAL STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 247,910, dated October 4, 1881.

Application filed August 5, 1881.

To all whom it may concern:

Be it known that I, MILTON W. HAZELTON, of the city, county, and State of New York, have invented a new and Improved Sectional Steam-Boiler, of which the following is a full,

clear, and exact description.

The object of this invention is to construct a boiler tliat shall be economical of fuel, quick to generate and superheat steam, easy of repair, and occupying comparatively little ground room.

In the accompanying drawings, Figure 1 is a sectional elevation of my improved boiler set .in brick-work on line to 10, Fig. 4. Fig. 2 is a The bottom of said cylinder Ais set on a suitable support, B, and around the lower end of said cylinder A is an annular ash-pit, 0, above which is the fire-chamber D, separated from plates, as shown in Fig. 4. The opposite fuelentrances into the fire-chamber D are represented at b I). From the top of the fire-chamberD to a point several inches below the grate E the cylinder A has an unbroken surface.

At the top of the fire-chamber D are two series of water-containing tubes, F, set conveniently close together, one above the other, radiating from the cylinder'A; and connected with these tubes F by elbows c c are perpendicular tubes F, that are extended downward through notches d in the edge of the grate E,

and .have their lower ends connected by elbows (No model.)

From j ust'above the tubes F nearly to the water-line of the boiler the space within the boiler-inclosing walls H is filled with series of tubes 1, closed at their outer ends and radiating from the cylinder A in successive planes one above the other, the tubes and spaces of the several series alternating with each other, as shown in Fig. 3, and above the upper series of tubes I, below the water-line, radiate from the cylinder A a series of tubes, K, whose ends are connected by elbows g with perpendicular tubes K, that extend downward almost in contact withthe boiler-walls H to below the tubes F and are at this point connected by elbows h with horizontal tubes K that are entered into the cylinder A.' By this arrangement of cylinder and tubes a maximum fire-- surface is obtained in a given space, and great economies in fuel are thereby made possible.

A little above the boiler water-line, which is indicated at is, Fig. 1, the cylinder A is enlarged into a steam-chamber, as shown at A and extending horizontally from about the bottom of this chamber A is a perforated circular disk, L, while from the top thereof extends another perforated circular disk, M.

Extending between the disks L M, and with their ends fitted in the perforations thereof, are vertical flues N, set in concentric circles about the steam-chamber A and serving for the escape of the products of combustion from the fire-chamber D.

A cap, 0, provided with a smoke-pipe, O,

surmounts the whole device.

The products of combustion escaping through the fines N serve to superheat the steam in the chamber A, and from said chamber A the steam is conducted through pipe P.

Having thus described my invention,I claim a as new and desire to secure by Letters Patent- 1. The combination, with a central upright cylindrical boiler, A, havinga series of radiating-tubes, I, closed at their outer ends and arrangedin successive planes one above the other, 9 5
