JAMES ROOT, OF CINCINNATI, OHIO.

CONSTRUCTION OF COOKING-STOVES.

Speccation of Letters Patent No. 2,250, dated September 11, 1841.

To ZU whom t may concern f Ile it known that I, JAMES Itoo'r, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain Improvements in Stoves for Cooking; and I do hereby declare that the following' is a full and exact description thereof.

In the accompanying' drawing', Figure 1, is a perspective view of my improved stove, and Fig. 2, a vertical section thereof, from front to back in the line ai fr, of Fig. 1.

A, is the fire chamber, in which either wood or coal may be used as fuel. Below the lire chamber is a large ash-pit B, which occupies the whole space between the grate hars C, C, and the bottom plate of the stove, being' equal to about one half of its height.

D, is an oven having a sliding' shelf E, within it. The hearth Il, is cast separately from the plat-es of the stove, and is subsequently attached to the front plate by means of brackets, or projecting pieces, G, cast thereon, or attached thereto. This forming of the hearth of an independent casting results from the particular construction of the stove; as it does not constitute a part of any horizontal plate within the stove the construction of the fire chamber and ashpit forbidding this as where the heart-h and fire lead are cast together a grate and ash pit cannot be employed as the movable bars, to be presently described, extend from end to end of the lire chamber, and constitute the only division between it and the ash pit. II, I-I, are openings through the front plate into t-he ash-pit.

I, is a removable back plate to the lire chamber, preventing the over-heating of the front oven plate J, and capable of being readily renewed if injured by the action of the fire. I sometimes, more especialy when coal is used as a fuel, cast t-he top plate of my stove without actual openings through it, for the reception of cooking' utensils; and instead thereof I .form depressions in said plate, the bottoms and sides of which are continuous, resembling' in appearance a skillet, or frying pan, as shown at a, a, in the section; by means of this pro-vision no smoke can escape when the cooking utensils are removed, while there is but little difference in the time required for boiling, or other cooking' operation, and the burning` of articles which are being cooked is effectually prevented. Each individual bar of my fireg'rate C, C, islhung upon a pivot, and is connected to a shaker handle K, in the manner shown in the drawing', by which means, not only may the ashes be shaken out, but the hars may be closed so as to admit of the covering of embers, and preserving' them in an ignited state. The flue I, from the fire chamber passes over the oven, down at the rear end of the stove, and under the oven to an ascending flue at one side, the upper part of which is seen at M, and its outline at I), Z). A partition plate, shown at L1, brought around in a curved direction and terminating at C, serves to conduct the heated air which has descended the rear iue, toward the fore part of the stove, without which it would pass immediately to the side Hue, and the lower plate of the oven would not be suiiiciently heated.

The course of the partition plate L1, is shown in Fig. 4, which represents the bottom plate of the stove.

A sliding` damper, shown separately in Fig. 3, is used to open or close a direct passage from the upper flue L, to the escape pipe at M, when it is not desired to heat the oven. The inner side N, of this sliding damper is elongated, so that when `drawn out it shall project to such distance into t-he upper flue L, as to cause the draft of heated air from the fire to pass in the vicinity of the openings fo-r the rear boilers, which it would not do without this provision. The place of the sliding damper is shown at N, Fig'. 2, and in dotted lines in Fig. 1. A top view of it is given also in Fig. 5, which is a section of t-he top ofthe stove with the top plate removed.

Having thus fully described the manner in which I combine and arrange the respective parts of my cooking stove, what I claim therein as new, and desire'to secure by Letters Patent, is-

1. The manner of arranging and combining the respective parts constituting the lirechamber, the ash-pit and the hearth; said arrangement and combination consisting of the fire-chamber and ash-pit separat-ed from each other by the grate bars C, C, only; which grate bars are each of the ordinary width of such bars, and each hung upon pivots, and connected with a handle by which they can be shaken, or closed, at pleasure; and of an independent hearth, not connected with any plate of the stove, eX- cepting by the brackets used to attach it to the front plate, all as Set forth. By which structed and arranged as that when ilrawn l0 out it shall intercept the draft of heated air, and cause it to pass in the vicinity of the rear Cooking utensils.

JAMES ROOT.
