having outwardly turned circumferential flanges, said flanges being joined by rivets, thus providing means for expansion and also stiffening rings or ribs at each sectional junc- My invention further consists of a sectionally-constructed furnace comprising in its construction a series of tubes having out- Wardly-turned circumferential fiange's, means for joining said flanges together, the front section being so constructed as to gradually diverge circumferentially toward the front,

`one-h alf portion of the boiler-front removed.
My invention further consists of a tubular boiler having a' front and rear head, one or more circular openings in the front head and one or more corresponding circular openings f in the rear head beneath the boiler-fines, the front openings being larger than their respective rear openings, inwardly-extending angular flanges around said openings in both heads, and means for furnace to said flanges. y

7 represents the front head of the boiler,

9 9 9, &c., represent the flues.
10 10, &c.,represent stay-rods.
11 represents the rear combustion-chamber, which is preferably constructed of brick with a fire-brick roof.
12 represents the grates, and 13 represents the hre-arch.
14 represents the furnace-opening inthe front head, and 15 represents the furnaceopening in the rear head. The furnaceopening in the front head is larger than the furnace-opening in the rear head. Circumferentially of said openings there is provided inwardly-extending angular flanges 16 and 16 front and rear.
It will be observed that in my invention the furnace is hung or suspended within the boiler and attached, by means of rivets 17 17 17 17, &c., to the flanges 16` and 16.
In my invention the tubular furnace isconstructed in sections 18 18 18, &c., each section being provided with outwardlyturned flanges, and these flanges being riveted together at 19 19 19, &c. The flanges when so riveted for ribs or rings to afford means of expansion and to further afford stiHening-ribs for the Asupport of the furnace.
The front section 20 is constructed gradually diverging circumferentially toward the front,
but with the same base as the base of the furnace.
The fire-front 21 is bolted to the boilerhead by a series of bolts 22 22 22, &c.
By means of my invention, the construction of the furnace and the front boiler-head opening being larger than the rear opening, I am able by removing the fire-front 22 and then knocking out the confining-rivets 17 17 17, onc.,v to withdraw the entire furnace through the front opening in the boiler-head. I regard this as an essential feature of my invention, because it is often necessary to repair the furnace, and` by withdrawing the same I afford a means of easily perfecting the re airs.
n my invention it will be observed that none of the boiler-fiues are below the furnace, and all are located practically above the furnace. In the operation of the furnace the bed or floor is relatively cold in comparison with the top of the furnace. Means must therefore be afforded to permit expansion and contraction or else the'furnace-jacket will warp. By means of my segmental or sectional construction, as described, I afford a series of joints which accommodate to the expansion and contraction of the furnace general line of IOO and further afford a series of ribs or rings to stiffen the furnace. By means of the upwardlyinclined top surface 20 the outward pressure of the steam toward the boiler-front is broken against the incline.
It will be observed that the roof of the eX- pansion-chamber is limited in height to the height of the tubes within the boiler. In
expansion-chambers heretofore constructed of this class the roof of the chamber has been allowed to join the boiler at the top line of the boiler. In such a construction the eX- cessive heat from the furnace radiating against the upper portion of the boiler, which is practically unbalanced, has caused a burning out of that portion and of the anchorages to the tie-rods l0 10, &c., or other braceerods that may be used.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is'- I 1. In a steam-boiler, an internal tubular furnace comprising in its construction sectional tubes having outwardly-turned circumferential anges and means for joining structed as to gradually diverge circumferentially toward the front, said section being upon the same line of base as the other section, said furnace being suspended from inwardly-turned anges around front and rear openings in the boiler-heads, and removable means for attaching said furnace to said Ranges, substantially as shown.
In testimony whereof I affix my signature in presence of two subscribing witnesses.
