Specification state art of Letters Patent No. 173,827, dated February 22, 1876; application filed December 28, 1875.

the city of Rochester, in thecounty of Monroe.

and State ofNew York, have invented a certain new and useful Improvement in Stoves and I do hereby declare that the following is a full, clear. andexact description of the construction and operation of thesame, reference be ing had to the accompanying drawings, in whichg Y Figure l is. a central vertical section in line y y, Fig. 2. Fig. 2 is a cross-section inline :1: Figs. 3 and 4 are perspective views of the interior front flue-plate. isan elevation of the register.

My improvement relates to wood-stoves, and is of that class in which a diving-flue is used, carrying the draft and products of combustion downward into the hollow base of the stove, and thence upward'into the smoke-pipe, where it escapes. The invention consists in the construction of the'flue-plate and register, as hereinafter more fully described. y y

A represents a sheet-iron wood-stove of ordinary cylindrical or other form. B is the castiron base,which is made hollow for the passage of the draft and products of combustion. G is the front, and U the rear, flue-plates, each of which cuts off asegment of the cylinder of the stove. The draft and products of combustion, passing down the front flue, enter the hollow base 13, thence pass up the rear fine,- and finally escape into the smoke-pipe. A damper, a, is, preferably, used in the rear flue to produce a direct draft when desired.

Thus far the stove isot' ordinary construction.

Ordinarily the flue-plate G is made of plane or straightform, simply cutting off a straight segment .of the cylinder, and thereby produc in ga dead-space occupying the whole segment. The top has usually been slotted or open, to admit the downward draft, which is very objectionable, as it admits ashes, which soon till and obstruct the passages. This difficulty is aggravated from the fact that in stoves of this kind much wood is burned endwise, and, where large sticks are inserted in this manner, ashes are not only sifted through the slotted top, but coals, pieces of bark, wood, and chips fall through and obstruct the flue. The cutting off of so large a segment of the stove also Fig.5

obstructs outward radiation of the heat, and much heatis thereby 10st, being carried off in.

a latent state. I construct this flue-plate of peculiar form. The top in is shelving crinelined, and is made closed, so as to throw off the ashes, coals, pieces of bark, wood, &c.., as

balance of the width of .the flue-plate is made of a single thickness, 1), which is curved, and

made close-fitting to the cylinder of the-stove. This allovvsthe direct radiation of the heat outward through the body of the stove, over the whole space thus covered by the single thickness of the flue-plate, instead of cutting it off by a dead-space, as Where the flue-plate is straight across. At the upper end of the plate adjoining the shelf at are formed flaps 0 c; and beneath these are the side ports or openings at cl, which communicate with the interior of the trunk C. These flaps cover and protect the ports, and prevent the entrance of ashes, &c., to' the trunk as they fall from above. At the bottom of the cavities formed by the curving ofthe plates 1) b are also inclines f f, which throw off the ashes, and pre vent their getting in the cavities, and thereby obviate suction of the ashes into the flue-space. The rear flue-plate O is similarly constructed,

the body being made narrow, having the curved sides I) b, and also the bottom inclines ff, as clearly shown in Fig. 2.

By the construction above described I se- .cure an increase of direct radiating-surface equal to the size of the curved sides b b, which, in ordinary stoves of, this kind, is lost by the cutting oli' of said space by a straight flueplate extending across from side to side of the stove. I also effectually prevent clogging of the ashes by making the whole exposed surface of the flue-plate closed, and inclining the same to throw olf the ashes into the body of the stove, while the passages to the. flue are housed or covered by the flaps c 0, so that no ashes can reach them. 'In these respects my device differs essentially from others of the kind. This improvement may be used with'a cylinder or any other shaped stove.

E is a draft-tube, extending through the front flue-plate near the bottom. Outside the cylinder it is coveredby an open casing or bonnet, G, which rises some distance above, as shown. In the front of this casingis fitted a register, g, which is simply a door or valve,

jointed to turn at the bottom, as shown at h, and open by swinging at the top. It may be gaged in its opening by spurs i t, which rest inside and catch the edge of the case, or by any equivalent arrangement. It may or may not haye a mica light, 70, as indicated in Fig.1.

1 The draft enters from above, as shown by the arrow, and, passing through the tube, sup

connection with a simple opening through the I cylinder, instead of the tube -E.

Having thus described my invention, I do not claim, broadly, flue-plates for producing downward draft in astoye. Neither do I claim, broadly, a register in front, which will prevent the snapping of coals upon the floor.

What I claim as new is- 1.In a cylinder or other shaped stove, the

flue-plate constructed with the central trunk G, curvedsides b b, and inclines m f, with the I ports or passages for the entrance of the draft,

housed or covered to prevent the entrance of ashes, as herein shown and described.

2. The combination, with the draft opening or tube E, of the exterior casing or jacket G and the swinging door g, capable of removal or turning back for the removal of coals, as shown and described.

In witness whereot'I have hereunto signed my name in the presence of two subscribing witnesses.
