To all lwhom it may concern:

Beit known that we, GORYDON WHEAT and ALFRED OA'rcHPoLE, both of Geneva, Ontario4 county, New York, have invented a certain new and useful Improvement in Heating-Appara-A tus; and we do hereby declare that the following is a full, clear, and exact description of the same,refercnce being had to the accompanying drawings, in which- Figure 1 is a central vertical section of a boiler, showing our improvement. Fig. 2 is a similar View at right angles to Fig. l. Fig. 3 is a section of one side ofthe upper portion of the apparatus, showing more particularly the means for extending the height of theniagazine. Fig. et is a plan view of the lower sec- Fig. 5 is a plan of one of the upper sectional rings D. Fig. 6 is a horizontal section of one of the upper rings D, enlarged. Figs. 7 and 8 are cross-sections of one of the rings D respectively in lines :v and y y of Figs.

5 and 6. Figs. 9 and l0 are detail views, showing the registers and slides. Fig. 11 is a bottom view ofthe dome. Fig. 12 is an elevation of two-of the rings D, exhibiting the notches therein for admitting the tubular door.

This improvement relates to steam-heating apparatus.

'lne objects sought in the invention are simplicity and cheapness of construction, safety against over -pressure, due to the form of the sectional rings, convenience of transportation, and ability to build up boilers of varying sizes with great facility and ease, either in stationary or portable form. i

The invention consists in the construction and arrangement of parts hereinaftermore definitely described and claimed.

In the drawings, A shows a base, forming the support for ,the sectional tubular rings, and having a grate, B, of ordinary form.

(l is a hollow tubular ring,which rests upon this base, the passage through the ring being unobstructed, j and said ring having two or more open-topped bulbs or enlargements, a a, Fig. 4, which allow the water to pass into the upper rings, which are of larger diameter.

D D are the upper sectional tubular rings, of which any desired number may be used, according to the size of boiler it is necessary to make. These rings are simply laid one on top of another, with suitable attaching devices for holding them firmly together.` Each of the rings D is constructed as follows: It is made i hollow for the free passage of water. It may be made of any desired form, both in outline and cross section; preferably, however, the rings are square in cross-section, to facilitate casting and to fit better in building up. On opposite sides are ports or passages b b, Fig. 5, which fit over the bulbs a 'a of the lower ring, O, and which fit over each other in the successive sections, so as to make a connected passage on the two opposite sides clear up to the top of the boiler. The ring is also provided with a series of open-ended Hue-tubes c c, arranged around the whole circumference, and when the rings are built up one on top of another these flue-tubes all come in line and make connected passage-ways from bottom to top, as shown in Fig. 2. At the bottom they open ontside the lower base-ring, C, which is of smaller diameter than the other rings, and at the top they open into a space, d, communicating with the nre-chamber E.

F is a hollow ,domesection, which its on top ofthe upper ring D, and has ports corresponding with the ports b b, by which the hot Water is allowed to enter the dome. It has also a downwardly -projecting Bange, e, which restsv on top of the upper ring, thereby forming the fire-space d, before described. It has likewise tubular passages ff, covered by Stoppers g g, through which a poker, brush, or rod may be inserted into the flues c c, for the purpose of cleaning the latter from soot and ashes. The parts thus constructed are all bolted together by bolts or" rods h h, which extend down from the dome through the ports b b, and are secured in place by nuts. The ports b b are divided centrally and vertically by partitions or webs it', which extend to and join with the adjacent ends of the two ues c c next to them, but extend no farther, so that the ues c c beyond aredisconnected from each other and the water can'ow freely around and between them. The partitions all coincide, and their ends meet, making thereby passage-ways from top to bottom. The dome F has the samepartitions i z',- but they are cleft or slotted in the center, as shown in the bottom view, Fig. 1l. By the means of these partitions t i a double passage- IOO way is made from topto bottom, and the hot cool water will descend the outer passage, thus i making a circuit, as indicated by the arrows, Fig. 7. In addition to this the partitions it' form posts or piers to strengthen the rings and prevent any crushing or springing of the rings under pressure.

G is an open-ended ring or cylinder, which rests on topot' the dome, and which we denomi- -nate the smoke-stack,since it has a smokepipe, H', extendingt'rom its back and opening into the main smoke-pipe H. On top of this ring rests the flange;` of acylinder, I, ot'smaller diameter, which rests within and extends through the ring, and has attached at its lower end the magazine J. The cylinder I has in its sides and near thetop a series of small holes, s2 s2, which open outward into the space bei tween the cylinderand the ring G,and form passages for the escape ot' gas from the top of the magazine into said space, whence it escapes through pipe H' into the main smoke-pipe H. By this means a free escape of gas is allowed and all danger of explosion is obviated.

The magazine is made of a series of overlapping rings, 7c la, forming sections that can be applied or removed at any time to make the magazine longer or shorter to correspond to the height to which the boileris built up. The cylinder I rests between projecting lugs l l in the eye ofthe dome, which center the cylinder and leave a circular space, m, through which the smoke and products of combustion can pass from the fire-chamber to the exit-pipe H' inthe ring G. On the angej of the cylinder I is a groove, a, in which tits the edge of the cover L, as shown in Fig. 2; or, in case it is desired to build the magazine higher, one or morerings, M, may be placed on the top of the cylinder I, and the cover be placed on -top ot' the Lipper ring, as shown in Fig. I. The grooves in which the edges rest are lled with sand to form a packing. and prevent the escape ofgas. Byr this construction it will be seen that the Y magazine and its connections are portable and can be removed and replaced withoutdifficulty, and, furthermore, the magazine is supported and retained in place by the ring G, and not by the boiler. In this manner the capacity ofthe magazine maybe increased at pleasure.

N is ajacket or casing, surrounding the Sectional rings and connecting the base with the dome, and leaving a thin space between itself and the rings, which simply forms a iiue for the escape of the products of combustion.

0 c, Fig. 5, are flanges forming partitions, which stand radially and vertically up and down between this'jacket and the rings D D, and divide the annular Iiue space into as many different and separate nues p p as there are anges. These anges come on a line between the iues c c of the'rings D D, so that the flue-spaces p p each comes opposite and covers one of the iiues c c, thereby imparting the maximum of heat to the water, which lies in a thin body between the two nues. These angeso 0 keep the heat from circling around indefinitely, and coniine the heat to straight currents covering the dues o 0. The flanges o 0 extend from the bottom of the lower ring D to the top ot' the upper one,their.length therefore being exactly the vertical height of the rings D D, and leaving the spaces above and below the rings open and unobstructed.

I is an exterior casing or jacket, extending from the base to a little distance above the dome, where it is carried in and strikes the ring G, thereby forming a jacket-space around the inner casing, N. Cold air is let in at the bottom of the exterior jacket-space and is passed out at the top through a pipe or pipes, and may be used to heat outside rooms. The exterior jacket serves to prevent the passage ot' heat outward, thus serving as a shield. If

desired, it may be dispensed with entir`ely.`

Slides or covers t' r are made in both the outside and inside casings to allow entrance to the space around the rings for the purpose of clearing the same ot' ashes and soot, which are swept out through holes provided with stoppers s s, as shown in Fig. l.

H2 is a branch of the smoke-pipe, which passes in and connects with the inner Huespace between the inner jacket and the rings. Both of the smoke-pipe branches H H2 have dampers u u, by which the draft can be controlled. -l

e is a sliding register on the fiange e of the dome F, coveringopenings through said flan ge. By moving the register' in one direction the draft from the nre-chamber will pass through the openings, and by moving it in the other direction the draft will be cut off. This is ot' service sometimes where it is desired to produce a draft less intense than that through pipe H and more intense than that through pipe H2. The register@ is on the opposite side from the smoke-pipes, and the draft therefrom has to make a half-circuit before it reaches the smoke-pipe H2, where it escapes.

R is a circular tubular door, set into the boiler through the casings and the rings, and reaching to the fire-chamber E, as shown in Fig. 2, by which means the tire may be reached at any time. The outer end is covered by a door or nap', w.. To allow the inner end ofthe lube to pass through the rings DD, two of said rings have openings or notches t t made therein, as shown in Fig. 12, the notch in each extending one-half the width of the ring, but leaving a free passage-way for the waterabove the notch, so that the water can circulate throughout the whole ring, thereby preserving uniformity in the expansion of the ring under heat. The tube It enters the opening thus made and makes a clear passage from the outside of the boiler to the tire.

S is the piping which' leads oft' from the top of the boiler through. the building to be heated, and T is the return-pipe, arrnn ged in the ordinary way.

VFrom the above description the operation will be readily understood. The water as it becomes heated in the rings rises through the .innerpassages to the top` and then descends IOO IOS

IIS

through the outer pasages, thus making a constant circulation.4 It also spreads and circulates throughout each ring, and in coming in contact with the dues c c it receives additional heat. In kindling or starting the tire, the valve u in vsmoke-pipe H is opened, which allows a direct draft upward, the draft passing through the circular space m. When the re is properly established this valve is closed and the valve in pipe H2 is opened. The draft then passes up through the hre-chamber over the top ofthe rings; thencepasses down through the uesc 0,-aud thence passes up again through the lines 1J p, between the jacket 'N and the rings, and tinally escapes, the heat thus snrrounding both the inner and outer sides of the rings also passing through the center, obtaining the best effect of the heat. By making the lower ring, U, ot' smaller diameter than the others, a space is left around the bottom which allows the draft to turn and circulate, and also gives room to clear out ashes and soot. The damper v allows an intermediate draft between the direct and indirect when desired.

The dome F is of peculiar construction. It is hollow and receives steam and water through ports lcommunicating with the ringsbelow.

It has a central eye or opening, through which the ring passes which supports the magazine. It has a vertical dan gc or skirting, which rests upon the upper ring and forms a tire space at the top ofthe re-ohamber, and it has an inclined bottom, which allows water to stand thereon-when the dome is dry.l thereby obviating cracking ofthe same under heat.

Havingthus described our invention, we claim- 1. In a heating apparatus consisting of a series of hollow watersections placed one u pon another, the bottom section, C, of less diameter than the upper sections, D, and communicating therewith by ports a a, the uppersections off setting or projecting beyond the bottom section, leaving a space in the bottom ot' the boiler, into which the dues c c of the upper sections open, and `in which are located the stoppers s s, asl'herein shown and described.

2. In a heating apparatus, theA hollow ring or section I), constructed with the ports or openings b b on opposite sides, forming waterways, the vertical partitions t', dividing said ports, andthe tlues c c, extending vertically through the ring, allin combination, as shown and described, and for the purpose specified. 3. In a heating apparatus, the combination of the several water rings orsections D D, placed one on top ot' another, forming :a stack, said rings provided on opposite sides with ports b b, divided vertically by partitions t' t, forming distinct water-channels from bottom to top of the rings, and provided with lues c c, forming draft-passages through the rings, as and for the purpose specified.

4. In a heating apparatus, the combinatio i of the dome F, having a central eye or opening, the separate ring Gr, resting on top ofthe dome, surrounding the eye or opening, and provided withan exit-pipe, H,which communicates with the main eXit-pipe,`and a loose cylinder, I, rest-ing on top of thering Gr, eX- tending down through the dome, forming an attachment for the magazine, and havingin its sides near the top a series of small holes, s2 s?,

for the escape of gas from the magazine into t 6.- In a steam-heating boiler, the combination, with the sectional rings D D and the casing N, of the radial anges or partitions o o, resting between the rings and the easing, said flanges extending from bottom to top of the series of rings, and forming iiues pp, which come opposite the ues c c of the rings, as,

herein shown and described.
