IMPROVEMENT IN BASE-BURNING STOVES.

Specification forming part of Letters Patent No. 66,957, dated July 23, 1867;

Reissue No. 3,426, dated May 11, 1869. I

To all whom it may concern:

Be it known that I, WILLIAM (J. DURANT, of West Troy, in the county of Albany and State of New York, have invented certain new and useful Improvements in Goal-Stoves; and

i I do hereby declare that the following is a full,

. boiler-plate and oven.

clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which -Figure lis a front view of a stove, a part of the front or outer plates being removed to show the deflector mouth-piece and the fuelmagazine. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a rear view, partly in section, of the same, showing an attached Fig. et'is a plan view of the under side of the fire-pot base-plate, showing the manner of suspending the firegrate and its bed-plata' Fig. 5 is a perspective view of a portable ash draw or pan with 'an improved bail; and Fig. 6 shows a compound deflector mouth-piece.

The same letters refer to like parts in each of said figures.

This invention relates to various improvements in parlor and other upright stoves.

The first part of my invention consists in a deflector-feeder or mouth-piece, in combination. with a magazine or fuel-supply chamber of stoves, said mouth-piece or feeder being arranged below and near to the throat or base of said magazine, in manner substantially as hereinafter described. This deflector mouthpiece is for the purpose of and operates to prevent all gases rising toward the fuel-reservoir from entering the same by deflectin g them outward from its throat or base toward airorifices, where, mixing with air, they are consumed, and the products of combustion pass off throughthe lateral diving-fines of the stove, thereby preventing collections of gases and products 'of combustion within said fuel-magazine.

The w=econd part of inyinvention consists in the improved manner of hanging or suspending t1 9 fire-grate bed-plate ring to the under side cf the fire-pot base-plate, by the combined means of hook-headed pendent lugs or black ets cast on or aflixed to said fire-pot base-plate, and by notches or. recesses made in the flange of the bed-plate in such respective positions therein as to coincide with the respective positions of said hooks or lugs on said baseplate, whereby said bed-plate wit-h its grate is easily and quickly slipped into its proper position for admitting of vibratory or shaking movement in horizontal directions about its center, and with like case it is displaced there from whenever necessary for purposes of repairs, substantiallyin manner as hereinafter described.

The third part of my invention consists in the employment, with the fire-grate, of a bedplate having a horizontal vibratory movement about its center, in combinatipn with a vibratory moving plate, connecting the operatingjournal of said grate with the back part of a close pocket or recess made in'the ash-pit, and covering or partitioning said journal end from the ash-pit, in manner substantially as hereinafter described. This improvement enables said fire-grate to be shaken in horizontal directions about its center and tilted or dumped. While so doing no ashes or dust can escape therefrom through said operating journal pocket into the room.

The fourth part of my invention consists in the construction of a bail for a por able ashpan, in manner substantially as hereinafter described, whereby the ash-pan, when carried by said bail, causes the same to take a fixed, immovable position on its lugs, in a manner that prevents the ash-pan from tipping or upsetting to spill ashes therefrom.

The fifth partof 1n y invention consists in. the application of. an extension-chan1ber, whose top forms a heating-plate, to the smoke pipe or flue of an upright st e, so that boilers or other vessels containing substances to be warmed may be conveniently placed upon the top plate of said extension-chamber,- also, in forming an oven upon said extension-chamber, if desired.

To enable others skilled in the art to make and use my said invention, I now proceed to fully describe its construction and operation.

Fig. 1 represents a'tuel-magazine or reservoir'stove for heating purposes, the same having an ash-pit, Y, fire-pot D, combustion or flame chamber S, cylindrical magazine B, and hotair chamber U, of the usual or suitable form and manner of construction. A diaphragm or partition plate, 1, divides the flame-chamber S from the hot-air chamber U, and it also stays and supports the base or throat of the'fucl-1nagazine B.

O, in Figs. 1 and 2, shows a deflector feeder or mouth-piece. Its external face or deflecting sides are funnelshaped, or so formed as to make an an gle of thirty to forty degrees, or thereabout, from aperpemlicular, so as to defleet rising heat and gases away from the magazine-throat, in manner as hereinafter described. This deflector month-piece is arranged at a distance of some three inches, or thereabout, below the base or throat of the magazine 13, and so as to act in combination therewith It is retained or suspended in such position thereto by links or rods 9, which are attached to projecting ears or lugs on said mouth-piece O, and which have their top ends hooked to loops on the under side of the partition-plate '1, said plate being depressed or sunk in its central part, encircling the magazine, so as to form of its central under surface a deflector -'surface, substantially as shown. This device 0 constitutes what I term a single deflector mouth-piece, and it is employed in those stoves having but ordinary dimensions, or a comparative shallowness in depth of flame-chamber, for which it is well adapted, and produces good practical results; but. in stoves wherein more than the usual height of flame-chamber or space between the firepot and division-plate 'l is wanted and usedJthcn I employ whatI term a compound deflector mouth-piece, substantially the same as shown in Fig. 6 of amlexed drawing, wherein two or more, if necessary, of said single deflect-or mouthpieces are attached together by means of links, and the compound set thus connected is then arranged in combined position with the base or throat of the fuel-magazine B, and suspended in such position thereto by means of links connecting with the loops on the partition-plate 'l, in manner as before mentioned.

The operation or action of this deflector mouth-piece, it thus substantially constructed and combined with the base or throat of a fuel-supply magazine, is as follows: lhe magazine being filled with fuel and the fire-pot in full operation, the combustible gases and hot products of combustion rising under said deflcctor mouth-piece, inthcir ascent impinge on the inclined faces of said mouth-piece, which defi ccts them outward toward the outer parts of the flame-chamber, asshown by the arrows in the drawing, and said deflected currents draw with and after them the gases his ing from or generated at and below the central parts of said mouth-piece, so that no gases rise into or collect; within the iuelonagazine, which, together with the admission oi' cold air to circulate around its outer sides, keeps said magazine snt'iiciently cool to prevent heating the fuel in its upper parts, thereby preventing all noxious fumes from being generated. there in to escape therefrom.

.ll is a bed-plate for sup 'iortin the lire-grate F. This bed-plate is of a ring form, with outward flange from its upper edge.

W is the fire-pot base-plate. To the under side-of this plate are affixed. or formed hookhcaded lugs or brackets o. The bed-plate E, by means oi the notches or recesses c in its flange, and arranged in such respective po sitions therein as to coincide with the respect ire positions of said hooks or brackets e on said base-plate, is, by such in cans, slipped easily and quickly 'ithin said hooks e. The bed.- plate is then turned until the said notches c are carried past the hooks a suiiicient distance to allow a proper range of motion without bringing the said. hooks and notches to coincide, so that it is suspended in proper position by its flange upon said books or lugs, and. has a vibratory or shaking movement upon said hooks horizontally about its center when desired. The :tirograte F is suspended in proper position within this 'bedplatc E, the short journal having its bearing directly in the bed plate rim in a notch made in its upper side, while the long or operating shank or journal 1) passes through a notch in the under snle of the bed-plate, and has its bearing in a yibraa close back side. in is the bottom plate, and

" the end dates of said rockets z theyi'orin- 1 7 l mg a close partition between the operating journal end and the ashpit, the front and top opening of said pocket being closed by a door or lid. This com bination of inovablchad-plate and fire-grate with a close-pocket movable plate covering the opcrating-journal end from the aslrpit, as described, prevents the escape of dust and ashes from the ash-pit while dumping or shaking said grate to cl an the same.

G is a portable ash-pan, having its position under the grate and within the ash-pit the right and left inside walls of this pan, at tachcd to or cast thereon, are square or parallel faced or an gular-sided carrying-lugs i. H is a bail, having an cyehole at each end sut iiciently large to easily slip over and turn down and up. on said lugs. At the bottom part of these respective eyeholes made a slot or notch, it, of a form and size to fit on and hug the said square or angular lugs i, which. prevents the ash-pan from rocking when. the bail is turned upright and. the pan lifted and carried by it, thereby preventing the ash-pan. from overturning, so as to spill ashes there from.

At any suitable part oi the exitor smoke pipe F, or just above that part of said pipe where the same connects with the direct-draft due V, is arranged on the said. pipe f. an on largonient or flue-chamber, L, which is covered. by a plate, K, upon which vessels for the purpose of heating or boiling their contr iron easin g, provided with an opening and with a closing door, thereby forming,,in connection with said plate and with the bottom of the flue-- chamber N, a useful even, m, in manner sub-' stantially as shown in the drawings. The enlargement L and the arrangement of smokepipes may, however, be of any other equivalent construction, asv long as on the smokepipe or exit-flue of an upright store a chamber is formed upon which articles to be heated may be placed,

Having thus described my invention, I claim as new and desire to secure by Letters Pat- 7 cut- 1. In combination with a fuel-magazine, P, of stoves, a deflector mouth-piece, 0, either of a single or compound form of construction, substantially as herein described, and arranged to operate as and for the purpose set forth.

2. The combination of hook-headed pendent lugs or brackets c on the fire-pot base-plate W with the respectively-located coinciding notches or recesses e in the flange of the bedplate ring E, substantially as described, for the purpose of easily and quickly mountin g or han ing said bed-plate ring with its fire-grate in operating position, as set forth.

3. The combination of the dumping fire grate with an under suspended and horizontally vibrating or shaking bed-plate, and with a lever operating them, when said fire-grate can be dumped, but not vibrated, independent of the bed-plate, substantially as and for the purpose set forth. v

4. In combination with a horizoutally-vibrating grate and bed-plate, and with a lever for shaking them, the terminating of the end of the journal or shank by which they are vibrated in a pocket, 2, so that said shank shall not project beyond the exterior of the stove,

but be accessible and operated from the outside by the shaker through a suitable opening in said exterior, substantially as and for the I
