JAMES GRAY, Oli" ALBANY, NEW YORK.

Letters Patent No, 84,109, dated November 17, 1868.

MAGAZINETSTOVB.

The Schedule referred to in these Letters Patent andmaking part of the same.

To all whom 'it may concern Be it known that 1, JAMES GRAY, of Albany, in the county. of Albany, and State of New York, have invented a new and improved Base-Burning Parlor- St-ove and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the :v an in tig. 3.

Figure 6 is a view of the under side of the stove-top.

Figure is a perspective view of the stove-top, a portion ofit being in section to show its interior construction.

Figure 8 is a perspective View of the lire-pot, with the outside descending fines leading to the base of the stovc,.and also an ascending due at the back of the same. v

Figure 9 is a plan of the base ofthe stove.

Similar letters of reference indicate corresponding parts in the several figures. v

The principal object of my invcntionis so to construct a base-burning stove that it will diffuse an equal, continuous, and agreeable heat from its entire surface, not burningthe air that comes in contact with one portion of its surface, and scarcely heating it at all in another, as many stoves of this class do. This object I attain by the construction of outside descending iiues, lez'iding from the combustion-chamber to the base of the stove, and. in the front portion of the same.

Also, in the construction of an annular tine, nearly surrounding the lower portion or base of the stove, and acting in couiunction with the upper ascending dues, an upper chamber receiving the products oi' combustion, and a flue descending from the same.

Also in the construction of an imperforated airchamber surrounding the lire-pot, and enclosing all of the ash-pit e;\cept the entrance to the same, as will be hereinafter more fully described.

Another object of my ii'ivention is to provide ameans of easy access to the eombustion-chamber of the stove, for the purpose of kindling a iire in the same, or to remove slag or other impurities iom the fire. This object I accomplish by constructing illuminated doors or windows above the tire-pot, and opening into the combustion-chamber, as will be hereinafter described. g

Another object of my invention is to provide in this class of stoves a means whereby a vessel may be heated at the top of the same, for evaporation or other purposes, as will be hereinafter described.

Another object of my invention is to provide a simple and edicient means of' producing a direct draught iiom the combustion-chamber, which I effect by connecting the same to the exit-iiue M by means of a damper, P, in flue L, as m'll be hereinafter more fully described.

Another object of my invention is so. to construct a damper, Q, between hooded chute orv passage I, and coal-supply reservoir H, that, whenever necessary, a free communication may be established between them, and also at the same time with the descending flue T, so as to allow of the free escape of gas from the coalreservoir H, through Hue T, into exit-due M, all of which is done without stopping or disarranging the draught of the tire. c

To enable others skilled in the art to understand my invention, I will here describe its construction and mode of' operation.

In the accompanying drawings, A represents the base-plate of the stove, upon which vertical plates a* are secured, forming the ash-pit B ofthe stove, The annular smoke-flue K is formed upon this base-plate A,

and also the bottom of the imperforate air-chamber J,

in the manner shown in fig. 9.

On the top of the ash-pit B is placed the outwardlyflaring and trumpet-mouth-shaped fire-pot C, the bottom oi' which is a gra-te, D, constructed in the wellknown nia-nner. p f

The coal-reservoir H is supported free from the tirepot by projections S, attached to it at points on a level with the top of ring F', upon which they rest, as shown in figs. 2 and 3.

In the lower or base-section, A', of the stove, and surrounding the ash-pit B and the fire-pot C, I form an iniperforate chamber, J, by continuing the outer wall oi' the base-section A to the base or bottom plate A, as shown in 2 and 3, the top or brim of the lire-pot C forming the top ofthe air-chamber, as shown in figs. 2 and 3. Said chamber J may be made imperforate, as shown in iig. 3, which I prefer, or it may have openings n in its bottom, as shown in fig. 9, or it may be perror-ated near its top and in its bottom, as shown at p j/ in 2.

At the bottom of air-chamber J, and surrounding it, I construct an annular flue, K, which encircles the Whole lower part of the stove, excepting the ash-pit Vopening 71., as shown in figs. 5 and 9.

the grate and fire-pot, and so arranged that the in- C, to and around the bottom of the stove, thereb)v flamed gases may burn in a free space, so construotproducing an equal degree of heat over the entire Surng and arranging such stove or-furnaoe, that a por-r face of the stove, substantially in the manner herein tion of the produets of combustion arising from the described.

re will be conducted up, around, and above the reser- JAMES GRAY.

Voir H and hooded chute I to the top ofthe stove, and Witnesses: at the same time another portion of said products of THOS. HOUGHTON, combustion will be carrieddown outside the. repot WM. GRAY.
