IMPROVEMENT IN COKENGF-STOVES.

Specification forming part of Letters Patent No. di,, dated January 30, 18-19.

To coZZ "whom '126 may concern:

Be it known that I, VILLIAM S'rEPHENsoN, of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in the Cooking- Stove,which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

Figure l is a vertical longitudinal section of the stove through the center of the same. Fig. 2 is a vertical transverse section through the back due. Fig. Sis a horizontal section tlrough the fire-chamber. Fig. 4 is a view of the inner side of one of the side plates of the oven containing the side flues. Fig. 5 is a view of the outside of said plate, showing the position of the side fiues.

Similar letters in the several figures refer to corresponding` parts.

My invention and improvement consists in constructing the stove with vertical ascending or descending side flues in the sides of the stove in which the ovendoors are usually placed and between the doors and corners of the stove through which the smoke and heat are caused to pass to a horizontal fine between the oven and fire-chamber and through a flue beneath the oven; also, in the arrangement of a sliding register-plate in the back flue of the stove, which, when open, will cause the draft to be from the fire-ehamber down the back corner flues and np through said register-plate directly to the smoke-pipe. Likewise in the arrangement of a movable fire-back in the firechamber for the purpose of increasing or diminishing the capacity of the fire-chamber at pleasure by moving said back toward or from the front of the stove.

A is the main body of the cook-stove,which is made much after the ordinary mode of forming cook-stoves. B is the fire-chamber. @is the oven; D D, desceuding fiues. E is the back fine. Fis the bottom fiue. G is the middle fiue passing between the the oven and firechamber. H is the front fiue. I I are two descending flues in the side plates of the stove, opening into the bottom flue. J J are two ascending flues made in the same plates opening into the middle fiue. K K are oblique plates for separating the corner fiues from the central fine over the oven. L is a horizontal perforated plate on which the register-plate slides. M is the register-plate. N is the handle for moving the register-plate. P is a turning damper for preventing the draft passing round the oven when said damper is closed. Q` is an inclined cast-iron back with inclined supports on the same, said back being designed to be moved toward or from the front of the stove, as it may be designed to increase or diniinish the size of the fire-chamber. R is a plate for dividing the central draft into two side drafts, g g, as it enters the smoke-pipe S at the rear of the stove.

1When the register-plate M is closed the draft will be down the corner fiues, D, into the back flue, ID, thence through the bottom fiue, F, up the front flue, H, to the middle fiue, G, and thence to the two side fiues, g g, at the junetion of these fiues with the smoke-pipe S, in the direction of the arrows l, 2, 3, and et, Sec., and also at the same time the draft will be clown through the rear side flues, I, to the bottom iiue, F, and thence up through the front side fiues, J, to themiddle flue, G,where the drafts will unite with those above mentioned and passing ..in the direction of the arrows. 'Vhen the register Mis open, the draft will be direct from the fire-chamber, down the rear corner fiues, and thence through the register to the smoke-pipe.

I do not claim forming chambers or spaces in'the side plates of the oven for the admission of heated air; nor do I' claim forming horizontal flues in connection with flues in the doors, as I believe thesehave been constructed; but

TWhat I do claim as my invention, and desire to secure by Letters Patent, is

The arrangement of the vertical descending and ascending flues I J, eonstructed in the side plates ofthe oven between the oven-doors and the corners of the stove, in combination with the fiues g g, leading from the middle fiue, G, to the smoke-pipe S, and in combination with these the arrangement of the sliding register M, as described and set forth.

In testimony whereof Ihave hereunto signed my name, before two subscribing witnesses, this 20th day of June, 1848.

IV. STEPHENSON.
