IMPROVEMENT lN COOKlNG-STOVES.

0 135 X Specification forming part of Letters Patent dated February 3,1836; Reissue No. 28, dated November 21, 1840.

entire stove in its different forms with said improvement'. Fig. 3 is a perspective view of the movable grate by itself with its movable top plate on A. Fig. 4 represents the plate with its boiler-holes in it taken entirely ofi.

Fig. 1 represents the fire-place or furnace drawn from under the oven on which its top plate, B, with boiler-holes in it, is made permanent to the movable part. Fig. 2 represents it shoved under the oven.

0 represents the oven or stationary part.

Drepresents the platform or hearth on which the fire-place moves."

E represents the sunken bottom or ash-pit.

The stove alluded to above is made in two parts-the one stationary, the other movable. That part which contains the fuel is movable, and is made to move backward and forward upon a cast-iron platform or hearth (represented by D, Figs. 1 and 2) under that part which contains the oven, (represented by 0,) thus making it occupy more or less space, or according to the use intended to be made of it.

The cast-iron platform or hearth (shown at Figs. 1 and 2) is made conformable in size with the furnace or movable part, and of a circular or oval form in front, while the back edge thelength of the oven is straight. It has asunken bottom, as E represents in the drawings, for ashes to pass into, and it is raised from the floor by legs ee e e far enough to protect the floor from burning, or as choice or "convenience may direct.

Over the sink (represented by E, Figs. 1 and 2) is placed a plate of east-iron, with openings running parallel with its side edges, and at any discretionary distance apart,.and about half the length of the plate, for ashes to pass through when the furnace is not di-- this.

rectly under the oven, as Fig. 1 represents it. On the under side, at or near its backedge, is a projection or flange, as shown by an end view, H, Fig. 5, extending down into the ash-pit about three-quarters of its depth, or more, to prevent theair from passing under, and thereby aid the stove in its draft. It is made to move backward and forward upon flanges or ledges, like sliding hearth in common use, and may be called a sliding hearth in (Shown at Q, Figs. 1 and 2.)

I will next proceed to describe the oven and'the other parts: The oven is constructed 'with doors in the ends and a single or double door in front, at my option, and is the stationary part, made standing upon the back part of the cast-iron platform or hearth on which the oven end plate, F, and its corresponding opposite plate and back plate at G are fixed,

which serve as legs or supports on which the.

oven rests. The plate F and its corresponding opposite plate should stand perpendicular with the platform or hearth, and be of such a I height as will form a good proportion with the hearth or platform on which they stand. About the center of the plate F and its corresponding opposite plate I draw a line parallel with the lower ends of the same plate. This line will show how high or how low the bottom plate of the oven will be. The back edge of these plates is made angular or curved. The front edge is nearly straight. The width and height of that part of the plate F and its I corresponding oppositeplate which comes next to the hearth and as far up as the ovenbottom governs the width and height of the movable fire-place, which will be hereinafter; described. The oven may be nearly square,

or a little curved on the back'part, and is surrounded by a flue formed onthe top by means of the top plate onthe back, by means of the 1 back plate running from the top plate in acurved or angular form, and partially under 4 the oven, conforming itself with the end plate, F, and its corresponding opposite plate, above described, to the back edge of the hearth f or platform on which the 'fi're-place or furnace moves. V

Inthe bottom plate. of theoven I make one or more boiler-holes for frying, &c., as shown i in the drawings; Through the inner top plate and back of the oven and along its front' edge, at equal distances from each end, Imake an opening (shown at Fig. 6) for the purpose of carrying ofi steam produced in the oven. Directly opposite to this, through the front plate, as at t, Fig. 2, another opening is madefor the same purpose, to carry off the steam generated in a cooking process from the movable part in front of the oven, by means of a tin fixed on the front edge of the top plate of the oven in such a manner that it may be taken off and put on at, pleasure. It has its front and end edges turned down, and when fixed on the oven to conduct the steam up the pipe it extends over the pots and kettles in a slanting position, and when occasion requires it may be turned up vertically against the pipe without taking it entirely ofl". Its length along the oven is nearly that of the oven.

J 1, represents said tin.

If, 'g. 1, represents the top plate with one or more boiler-holes, and P the pipe or collar. Directly under the collar or pipe I fix a damper (shown at c c, Fig. 6) extending the whole length of the oven, dividing the pipe in the center and in such a manner that when it lies down flatwise it closes the opening in the u per plate of the oven, and when turned up gewise by a handle (represented by 0, Figs. 1 and 2, and also Fig. 6) it opens it again, and also divides the smoke of the wood from the steam. There is a smallflange, z, Fig. 7, on the under side of the top plate, for it to strike against when turned up, running through the center-of the pipe-hole and the whole len h of the oven. in the center in a similar manner, as Fig. 6 shows, and also Fig. 7, and one sectional joint of the pipe may also be divided. The part containing the fuel or movable part (represented by B, Fig. 1, &c., is made of such a size as to freely slide under the oven and handsomely flll'np the space which is surrounded by tlifi'lower end of the oven end plate, F, and its corresponding opposite plate plate at G, and oven-bottom, &c. In one end of the fire-place or furnace I make an opening for a door to put in 'fuel. The door is without hinges and put on with a slide. 0n the side opposite the handle little catches are fixed to hold the door when slid in.

8 represents theopening. In Fig. 8, a represents the door, and d d the catches. A door is also provided at g, Figs. 1- and 2, so that when the furnace is shoved under the oven,-

these two will coincide with each other. The

front is made with doors extending down about The pipe-collar is also divi ed BEST AVAILABLE COPY as may be seen in Figs. 1 and 2.. Openings are also provided in the bottom plate of the fire-place at X, Fig. 9, to let ashes pass through into the ash-pit, also to give draft to the fire. Under these openings little slides like dumpers may be fixed, so that they may be opened orshut, as occasion may require, by means of a wire attached to them. (Represented by wand 11, Figs. 1 and 2.) The back plate of the fireplace forms an angle with the bottom plate of about thirty-five degrees, and is carried nearly as high up as the other parts of the furnace or fire-place, by which means a flue is provided. Its upper edge may be scalloped in rear of each boiler-hole, or left straight. Next I apply a top plate with boiler-holes in it, and make it permanent with the other parts of the furnace. v B, Fig. 1, is a top view of this part with its boiler-holes, &c. The covers to the boilerholes in my stoves are made to form a perfect bevel with the plates in which they are placed, so that when the fire-place or furnace is shoved under the oven a double bottom is formed to the oven, which has the effect of regulating the heat, 850., in its action upon the oven; or the heat may be allowed to act to a greater or less de ree upon the oven by moving the fireplace rther in or out. or presenting it covered or uncovered. When the fire-place is shoved underthe oven with the openings uncovered, the openings in the top plate of the fire-place will come directly under that in the bottom plate of the oven, (shown at f in Fig. 2,) and cooking may be done'in the oven, &c.

Having thus described my stove for burning wood, let it be understood in this corrected description and specification for reissue for the same invention I do not claim the bare grate to slide from and under an oven, believing that is not new.

What I do claim, therefore, as my improvement, and desire to secure by Letters Patent,

The movable fire-place or furnace, as specified, constructed with a top plate having boiler-holes in it, as set forth, in'combination with the stationary ovenyso, that when the fireplace with said boiler plate on the top is shoved under the even a double bottom is formed to the oven, which has the effect of regulating the heat in its action upon the oven, & e., all as herein described.

Subscribed this 15th day of September, 1840.
