IMPROVEMENT IN HEATING-STOVES.

Specification forming part of Letters Patent No. 142,075, dated August 26, `1873; application filed April 22, 1873.

To all whom it may concern:

Beit known that I, RICHARD H. BROWN, of Linneus, Linn county, State of Missouri, have invented new and useful Improvements in Heating-Stoves, of which the following is a full, clear, and exact description, reference being had to the annexed drawing and to the letters of reference marked thereon, in which- Figure l is a central longitudinal sectional elevation. Fig. 2 is a central transverse seetional elevation 5 and Fig. 3 is a top view, the dotted lines indicatingthe position of the iiues.

Like letters of like kind indicate like parts.

Mfy invention relates to improvements in that class of wood-heating stoves known to the trade as the Todd 7 pattern, the general characteristic of which class being a sheet-iron body, oval iu cross-sectional elevation, having cast-iron heads, and provided with a flue eX- tending throughout its bottom and partly up the sides, through which, by means of a suitable damper, the heated products of combustion can be directed, if desired. As usually arranged, the exit-flue passes out of the stove at about the center of its side, and the opening by which direct draft into the exit-due from the body ofthe stove is' obtained is arranged at the same point. This necessarily brings the opening not above the level of the top of the doorway in front, even when the door is unusually small; and when the door is made large, as is generally the construction in this class of stoves, the opening into the eXit-iiue is considerably belowr the top of the stove-door opening. Owing to this relative arrangement the smoke, when the door is opened, is apt to escape through the doorway into the room, rather than into the exit-flue. v To obviate this escape of smoke, and at the same time obtain a construction in the upper part of the stove that is both useful and ornamental, is mainly the object of my invention, which consists,

' principally, in a peculiarly constructed and arranged exit-due, in combination -with a saddle of novel construction and arrangement, substantially as is hereinafter set forth.

A, Figs. -l, 2, and 3, represents a stove of the'class above referred to. B B', respectively, are the ends thereof, or front and back, and of theusual kind. O represents the plate thatfornis the usual iue I) at the bottom of the stove. E, Figs. l, 2, and 3, represents the exit-flue of the ordinary height. Connecting with this flue E is the extension F, which eX- tends upward inside the stove and at the side thereof until it nearly reaches the top of the stove, at which point it passes up and out of the stove. This last-mentioned extension of the exit-hue is represented by the letter F. G represents the customary saddle-piece on top of the stove. It is provided with an ordinary opening, g, that is closed by an ordinary cover, As shown in Figs. 2 and 3, the saddle G is extended on the side, so as to form the upper Y part of the extension of the exit-Hue. The top of the stove, at the center, is`cut away in shape and size corresponding to the saddle G, which is there attached, and which rises slightly above the stove'.` This construction forms a chamber, H, in the top of the stove. Between this chamber H and the extension M is a partition-wall, I, in which is the opening J leading directly from the body of the stove into the saddle-extension M. This opening J can be closed by a suitable damper, K, operatel by a rod extending through the front of the stove. A drum can be used on. top` of the stove, in which case it is constructed so as to cover all the saddle G and receive the saddle extension M. In kindling the fire, and in replenishin g it, the damper K is opened. When started the `damper is closed and the products of combustion deiected through the bottom flue D and up through the lines E and F. Owing to the arrangement of the openingJ in the uppermost part of the stove, where the smoke accumulates mostly, and to the directness of draft into the upper part of the eXit-iiue, the smoke escapes directly into the exit-flue, even when the door is opened. The inner wall of the exit-flue E, and also of the extension F, is readily and strongly made by casting. The saddle-extension M is also cast in one piece withthe saddle G. I prefer to use this im proved exitiue in a stove that is provided with the peculiarly-constructed diving-nues and cold-air flue described in my'previous application f or patent for improvements in heatingstoves, tiled March 8, 1873, and as shown in Figs. 2 and 3; but it can be'applied in any description ofheating-stove of the above-mentioned class.

When the Todd pattern of stove is used with u drum, as shown in said former applic-2ttion, the connection between the exit-flue and the drum must be made by an elbow outside the stove-body, and an elbow when thus used is a-ptto twist the drum out of place, unless the drum is fastened securely to the stove. One advantage of my present construction is dispensing with sueh elbow, thus making it a simple and inexpensive matter to attach a drum to this class of stove.

I am aware the inner shell or hre-plate has been extended to the top of this class of stove, -for the purpose of discharging the products of combustion at the top of the stove; consemams queutly I do not claim, broadly, such con. struction; but

Having described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

The stove A, the bottom flue D, the exitlue E, extension F, opening J, damper K, saddle G, and extension M, combined, constructed, arranged, and operating substantially as described and shown.
