ARCHIBALD IVIETING, OF MIDDLETOIVN, PENNSYLVANIA.

COOKING-STOVE.

Specication of Letters Patent No. 3,860, dated December 16,-` 1844.

To all whom t may concern.'

Be it known that I, ARCHIBALD VIETING, of Middletown, in the county of Dauphin and State of Pennsylvania, have invented a new and useful `Improvement in Cooking- Stoves, which isdescribed as follows, reference being had tothe annexed drawings of the same, making part o-f this specification.

Figure l is a perspective view of the stove with the side and back plates removed, showing a part of the interior arrangement. Fig. 2 is a horizontal section through the lower flues. Fig. 3 is a horizo-ntal section through the upper flues. Fig. 4 is a horizontal section through the middle iiues. Fig. 5 is a vertical longitudinal section on the line .r of Figs. 2 and 3. Fig. 6 is a l vertical section through the pipe, and force or section pump c. Fig. 7 is a perspective view of the whole stove.

The general arrangement of the irechamber A-small oven B-boiler holes C- large oven D-funnel E, and hearth F-is similar to other cooking stoves in use.

The improvement that I have made is in the arrangement of the flues for the proper diffusion of the heat throughout the stove for regularity and economy in cooking and in the arrangement of certain dampers for changing the direction of the heat at pleasure--and likewise in the arrangement of'a force or suction pump in combination with the stove for producing a draft through the stove before it is heated.

Between the lire chamber A, and the small oven B, I form a vertical space eX- tending from one side of the stove to the other; in the middle of which I place a vertical plate p extending across said space, from the top plate `of the large oven, to the level of the top plate of the small oven,

, thus dividing said space into twovertical diving iues G, I-I, which lead into horizontal side fines I, J, extending to the front of the stove and dividing the space between the ovens and hearth into three fines by vertical `turning plates K, K, arranged' directly under t-he lower edge of the plate forming the back of the first mentioned flues G, IVI. When the plates 7c, 7a, are turned and brought to a horizontal position, the flues I, J, will communicate the one with the other, between the two ovens. The fines' I, J, where they pass under the hearth are formed into the aforesaid two side flues by the side plates of the ash pit L, which plates also form` the inner sides of said fines. These flues I, J, lead into a space formed between the front of the large oven, and the front of the stove, said space being divided by a vertical cross plate a, into two front .diving. flues M, `N. These tiues lead into twozig-zag flues P, Q, eX- tending the whole length and breadth of the stove, and of the` large oven, under which they pass, one of `said front diving flues leading into one of said zig-zag fines, and

the other diving' flue into `the opposite zigzag flue. These tlues P, Q, lead into two rear ascending flues R, S, that lead into the smoke funnel E, at the rear of the small oven B. The vertical cross plate T that divides the space behind the large oven into the two rear ascending' iiues extends from the bottom plate of the stove to the level of the bottom of the small oven. Upon the top or in this plate, turns one of the pivots of a turning damper U, for changing the draft. The other pivot forms also the handle, and passes through the side of the stove. There is another turning damper V placed at the junction of the flue I, with the Iiue R, for uniting 0r Vseparating said lues at pleasure` One of its pivots passes through the opposite side of the stove and forms a handle by which it is turned. lVhen these dampers U, V, are in the position represented in Fig. l, the draft will be in the direction of the arrows, obliquely across from one of the rear corners, to the opposite front corner. Through the fines I, J, to the front diving i'lue N, through which it will descend to the flue Q and after passing through said flue will ascend through the iue R to the funnel, having previously passed down flue II along flue J, down iiue M, and back through thezig zag' flue P and vertical iue S, by which the smoke and heat are made to circulate twice, entirely through the stove. There is a direct flue o between the perforated top plate of the stove and the top of the small oven leading from the lire chamber to the funnel. This iiue is divided from the fire chamber by a vertical plate Y and the sliding dampers W' and X. It is also separated at the middle into two sections by a central plate q l When the stove is cold, there will be very little draft and therefore in order to produce a partial vacuum in the stove at the rear part thereof I have combined and arranged a suction or force pump c Which is placed at an opening leading into the funnel, or in any convenient place, and when operated in the manner of a pump, will produce a draft from. the lire-chamber to the funnel.

A sliding damper W, before referred to is made to slide back and forth, over one third of the space, forming` the flue leading from the re chamber to the funnel, over the small oven, for opening and closing said flue at pleasure, and for directing the heat to the side boilers. The opposite damper X, is fora similar purpose. There is also a horizontal sliding damper Z, placed over the entrance to the flue Gr to be closed When it is required to turn the draft directly from the fire chamber down the flue H, as described and represented. When this damper and the damper U are open the draft Will pass through all the flues simultaneously.
