COOKING-STOVE Specification of Letters Patent No. 3,526, dated April 4, 1844.

To all whom 2'15 may concern:

Be it known that I, ABNER LELAND, of Milton, in the county of Northumberland and State of Pennsylvania, have invented a new and useful Improvement in Cooking- Stoves, and that the following is a full and exact description of the construction and operation of the same.

In the annexedidrawings, Figure l is a perspective vlew of the stove; Flg. 2, the

elevation of the front and Fig. 3 of the back of the stove; Fig. 4- is a transverse vertical section through the ash-grate; and Fig. 5 a vertical section lengthwise through the center of the stove.

The same letters refer to thesame parts in all the figures.

A, is the fire-chamber, with a movable grate B, which may be taken out.

a, is the bottom or hearth plate, which also forms the top plate of the oven, N. b, is a loose plate used in connection with the grate for the purpose. of conveying the draft from the two openings or air-holes c, c, in the back plate of the stove, this plate is removed when wood is used instead of c0211; (Z, a, are the side plates; 6, e, the inner side plates which extend from the bottom plate C, to within an inch or two of the top plate D, of the stove, each inner plate forming with the outer a double side with a space It, between. These inner plates have two small movableplates f, f, opposite the grate,

which are taken out when the grate is used, but are left in when wood is employed for fuel; they arelikewise notched out at their lower front cornersg, 9, so as to make a communicatlon between the side spaces 72,, it,

and the space or flue, m, under the bottom plate, a, of the oven.

2', is the door of the fire chamber having an air-hole at 2, and, is, is the upper drafthole which communicates with the smokefunnel E, and is furnished with a damper for closing it. a The backend of the hearth plate is pierced with opening at Z, Z, through which the ashes when pushed baclrfallinto the shoots F, F, and are conveyed away through the openings 79, 79, in the back plate, which being furnished with dampers, also serve the purposes of draft holes; by this means the hearth may be kept free from ashes, which is a great advantage in baking in the oven below, as they would prevent the heat from passing through the plate, and thus defeat the operation of baking a good crust on the bread, &c.

P, is the lower or dipping flue, Q, the oven door, and w, a hole immediately under it in the front plate for removing the soot, it should be closed with a door, which may have a regulating valve in it which would sometimes befound convenient to check the draft under the oven.

9, r, s, t, are circular openings in the top to receive the pots and other utensils. They are furnished with covers to close them when not in use, and the two g, 9, have a loose section 00, which can be removed so as to throw them into one for the purpose of using a large elliptical boiler.

When it is designed to use the top of the stove the damper 7c, is opened, through which the draft after heating the pots passes direct into the smoke funnel, fresh air being supplied through the openings 0, c,

in the back of the stove and (if necessary) equally around the oven.

The degree of heat is regulated either by at w. When the fuel used is wood, the grate B, and loose plate 6, are removed and the small side plates f f, are replaced. The

oven door instead of being placed in front maybe made in the side as shown by the dotted lines in Fig. l.

Nowwhat I claim as new and as my invention in the above describedrstove for which I ask Letters Patent of the United States, is-

The open space between the fire-chamber and oven, and in combination therewith the ash tubes with their grate for discharging the ashes.

Given under my hand this 15th day of March A. D. 1844.

ABNER LELAND.
