We, SHERMAN S. Jnwnrr and FRANCIS H. Roor, of the city of'Bufialqconnty of Erie and State of New York, haveinventeda certain Improvement in Cooking- Stoves, 'of which they-following is a specification. i i

' Our improvement relates to what are known as rear extension stoves; and

The invcntion consists in extending the boiler-flue,

T of a the full width of the stove, backward beyond the driving-fines and' back-plate of the stove, and proriding it with a damperat its rear, opening directly into the upcast-flue, which extends backward under the said extension and upward at its rear, in the form of a projection therefrom, whereby such extcn'sion'can be heated toa sufficiently high temperture to enable it to be used for the ordinary purposes of cooking or heating water when a boiler or reservoir is arranged thereon, in the same manner as theforward portionsof the stove, all as hereinafter shown and described' y a a In the accompanying drawing-- Figure I is a central verticalisection of our improved stove. i 1 Figure II'is a pl'anof the rear portion. fl Figure III is ahorieont-al section through theboiler- Like letters of reference designate like parts in eachlof the figures Aisthe oven.

B, the boiler-flue. CO, the diving-fines. v D, the return and upcast-rfluc, and D, alwater-bofler. j The top plate f of the stove, and bottom plate f of the boiler-flue, extend back beyond the diving-fines so as to form an extensionor heating-chamber, F, the top plate of which we prefer to provide with suitable holes to receive a water-boiler, as shown, or any other ordinary vessel, as may be required.

The back-plate of the diving and upcast-flues is madeto incline backward from the bottom, as shown in fig. I,.so as to enlarge the mouths of the diving flues, whiehfacilitatcs the draught, while it brings the rear portionof the months under the boiler, or other vessel placed over the extension F.

The upcast-flue, as it reaches the bottom plate f of thc'boiler-flue, extends hackwardunder it and up at the rear of the extension 1 from which it projects, as shown. a

G is the damper-in the center of the back plate of the. extension F, through which the products of com bustion from the boiler-flue can be let directlyinto the .upcast, when required.

The space F, formed by the backward extension of the top and bottom plates ff of the boiler-fine, as before described, and which is of the, full width of the stove, forms a chamber in which a portion of the heat from the'boiler-flue reverberates before it enters the enlarged mouths of the diving-fines.

By this construction the requisite temperature for cooking, or other culinary operations,'can be obtained in the extension F even when the' oven is employed in baking, which obviates the great objection that exists against the rear-extension stoves now in use,'which are mainly heated bythe return or upcastflue.

The damper G, at the rear of the extension F, communicating with the upcast-flue D, which is arranged below and at the rear of the latter, as before described, converts the entire width of the extensoin, when the damper is opened, into a direct boiler-flue, and sub Witnesses Jar ,HYATT, Jxo.
