COOKING-STOVE.

Specification of Letters Patent No. 2,468, dated February 21, 1842.

T 0 all whom t may concern Be it known that I, IVILLIAM B. ZEIGLER, of Huntingdon, in the county of IIuntingdon and State of Pennsylvania, have invented a new and useful Improvement in CookingeStoves, which is described as follows, reference being had to the annexed drawings of the same, making part o-f this specilication.

Figure l is a vertical longitudinal section. Fig. 2 is a perspective view. Fig. 3 is a perspective view of the rear end of the stove, the back plate Q, being removed from its place.

Similar' letters refer to corresponding parts.

This improved stove consists of a fire chamber A, with doors B in front, and doors C at the sides, having a rectangular oven D constructed in the rear thereof and an air chamber E between the two to prevent the end plate of the oven becoming too hot for regular backing formed by the end plate of the oven D and a guard plate WV at the back of the fire chamber and having constructed over and under, and at the rear end of said oven iues F-for the draftmthe top plate G of the stove forming the top of the upper flue being perforated for boilers and the rear end plate Q having an aperture `H for the passage of the smoke inte the funnel I, said aperture being closed at pleasure by a horizontal sliding damper K. The back-plate of the fire chamber A is movable and forms a vertical sliding damper L which closes alternately the flue F', F over and under, the oven D being raised and lowered against the guard plate W by `a lever M arranged directly behind said damper, the leverpassing through an opening in the side plate of the oven, its fulcrum being a pin or stud V passing horizontally into the guard W. The top plate of the lire chamber is perforated with boiler holes. The bottom plate is eX- tended in front of the tire chamber and forms the hearth. Underneath the lire chamber and the oven just described is arranged a large rectangular oven O eXtending the whole length and breadth of the stove excepting the fines; over and under, and at each end of this oven are formed flues f, for the circulation of hot air smoke and gases. This oven is furnished with side doors for the introduction of the articles to be cooked turning on quandrant or other hinges. When the sliding damper L is down so as to close the iue under the small oven D and the rear damper K is open the draft will be through the top iue direct to the funnel I. When the' back flue is closed the draft will be` turned down at the back of the large oven O and under and over it and into the funnel I. To effect this change of draft the plates at the rear end of the stove are constructed and arranged as follows: The horizontal plate R which divides the space between the two ovens into two horizontal flues F2 and f and also the top plate of the lower oven O, are, at the middle, say about one third their width, eX- tended to the back plate Q of the stove above and below the inlet S leading to the funnel I, having small vertical end plates T carried up from, the plate O2 above plate R and as high as the level of the bottom of the oven D over the top edges of which plates T the smo-ke is made to dive in its passage down and under and over the oven O into the funnel I through a middle flue as indicated by the arrows in Fig. 3, when the damper K is closed over the opening I-I. When this damper is open' or drawn back as repre sented in Figs. 2 and 3, the draft will be directly over or under the oven D through flue H into funnel I. Then this damper is closed the draft will be forced around the large or bottom oven O by the before described eXtension of the plates R and O2 and the end plates T forming the middle flue to the funnel I and cutting off all communica tion to said funnel except thro-ugh the said middle flue.

Vhen the sliding plate L is raised the draft will be under the small oven D and when only partly raised the draft will be over and under the small oven at the same time and should the back damper K be closed the draft will be aro-und the large oven and through the vertical funnel I as indicated by the arrows, as before described.

The sliding plate K may be of the same shape as the lue IVI, round or square. Its handle 7c passes horizontally through an aperture in the back plate of the funnel I. It moves over a horizontal rod U passed through the back plate' Q of the stove and the back plate of the funnel. The sliding plate L is rectangular.

What I claim as my invention and which I desire to secure by Letters Patent s- The Inode of combining the two ovens D and O with the re chamber A, said ovens having an arrangement of flues and the fire chamber being constructed with a sliding plate at its back to allow of the draft crculatng around either of the ovens as set forth. 10
