W. TREADWELL, OF ALBANY, NEW YORK.

BASE-BURNING STOVE.

To all whom t may concern.:

Beit known that I, W. B.TREADWELL, of the city and county of Albany, State of New York, have invented certain new a-nd useful Improvements in Supply-Cylinder Base-Burning Stoves, and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyin g drawings, making a part of this speciication,'in which- Figure l is a transverse section through my improved stove. Fig. 2 is a section takenV through the stove in a vertical plane at right angles to Fig. l. Fig. 3 is a horizontal section and bottom view of the base ofthe stove. Fig. 4 is a perspective view of the rebrick section of the stove. Fig. 5 shows in a sectional view the manner of constructing the mica door of the stove.

Similar lettersof reference indicate corresponding parts in the several figures.

In the operation of stoves constructed under my patent of September 29, 1863, the products ot' combustion either descend into the base of the stove, or, ascending, they pass into the flue surrounding the feed-cylinder. Under the operation,descending, the upper part ofthe stove is not heated. Under the operation, ascending, the base of the stove is not heated.

In the operation of stoves constructed under the patent granted to me November l, 1564, the products of combustion both ascend and descend at the same time by means of the use ot a perforated damper, in which latter case the stove can be'well heated throughout at all times; but there are one or two objections to this mode of constructing my stoves,which the present invention is intended to remove,

'as will be hereinafter described.

To enable others skilled in the art to make and use my invention, I will describe its construction and operation. p

In the accompanying drawings, A represents the base of the stove, within which are chambers or flues divided by partitionplates a a.. Chamber a: occupies the center of the base, running across fromrear to front, and chambers T T are located on each side of chamber as shown in Figs. l and 3.

. B is the ash-pit section of the stove, the upper plate of which forms a support for the grate and the re-pot. Plates b b, arranged in a vertical plane and extending across said section, form chambers O O, as shown in Fig. l, and in these plates ashvalves c c are formed, which open into chambers O O.

C is the nre-pot, with inclined sides. and which should have its interior surface ribbed or corrugated. It has a lipped project-ion, d, flarin g upward, as shown in Fig. 2, to give free passage to the coals in descending, so as to prevent the obstruction of the light. This pot (l has also a lipped projection, e, fiar-ing outward and upward, as shown in Figs. l and 2.

' D is the plate which forms the brim to the cast-iron fire-pot G, and the plate upon which the fire-brick section of the iirechambcrs rest, the back part of which plate is carried'up at an angle, j', to correspond with the angle e of the cast-iron fire-pot, which, united, lead to `flue L behind the stove. Thus formed, no

coals in descending can lodge upon the plate, and none will drop into the tlue.'

It will be evident that I obtain room or space at the point where the mica window is located, and at the point where the ilue or passage g is loca ted, for the expansion of the gasesof combustion, without'increasing the diameter of the fire-pot at any other than these points, and thus the object I have been seeking after is obtained, while the main body of fuel is compacted together and burned within a firepot of ordinary size or diameter, except at the two points named.

Heretofore stoves haveV been constructed with a tire-pot of much larger diameter at all points than the diameter ofthe magazine, and therefore the body of coals have not been held together as compactly as desirable. Besides this, stoves of this class have not had both an upward and downward draft outside the magazine, except in such instances as my own prevous inventions show, and hence the necessity for the construction I have herein described and represented has not been apparent.

E represents the fire-brick, arranged in the form of an arch, forming the upper section of the trechamber, and being supported upon the plate D. Flue g is formed through said firebrick, as shown in Fig. 2, with the cap hresting at pointz' i, Fig. 4. An opening, 7c, is also made at thefront part ofthe tire-brick section, which is covered by the key-brick m, which is held in position by cast-iron jambs at o o.

F is a mica door, which is hung on one side of the opening into the fire-chamber bya hinge,

I j, and fastened by a common turnkey, n, at

the opposite side ot' said opening. The basering77 s is formed upon the outer casing ofthe stove, Which ring holds the mica rmly and prevents the escape of gas when the door is closed.

M M are ascending tlues, placed at the sides of the cast-iron section of the tire-chamber, and are ot' about the same length or height of this section, as shown in Fig. 1.

G is the feed-cylinder, with its bearings at bearings at points s s.

H H represent a tlue surrounding the feedcylinder and the tire-brick Vsection of the tirechamber. v

I is a valve situated a-t the head of or alittle above chamber k in iiue L, as shown in Fig. 2. When this valve is open, it gives a direct dra-ft to the stove to aid in liindling the tire quickly. Valve I is perforated, as shown at r, so that in all cases, when it is closed, the gases have direct exit and cannot escape into the room under any circumstances.

The register l in 'line L is for the purpose of controlling combustion, and the valves c c, above referred to, are for the purpose of carrying oit' the dust While shaking the grate.

In a stove thus constructed the products of combustion pass from the refchamber (the valve I being closed) through the iue g into chamber K behind, as shown in Fig. 2; thence through descending tlueJ into the base of the ot' the stove. Passing thence directly forward through chamber x, they turn into the chambers T T to the right and to the left; thence ascending into chambers o o and continuing upward, they pass through ues M M into chambers H H, which surrounds the feed-cylinder and the nre-brick section of the iirechamber. From this chamber H the products ot' combustion pass through the branch lue N in to the escape-Hue L above the valve I. Flue H has a casing of sheet metal surrounding it, which gives a large radiating-surface. Thus constructed, the products of combustion are held longer Within the stove; consequently the radiation of the heat from the stove Will be Y tially in the manner and for the purpose described.
