Specification of Letterslatent ltfo. 8,242 dated Ju1y 2 2, 1851 To all whom, it may concern Be it known that, I, N. A. BOYNTON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Parlor Cook ing-Stoves, and thatthe following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principlesfof my said improvements, by which my invention may be distinguished from others of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent."

My improvements consist in the arrangement of fines about the oven, by which the heat, smoke, &c.,lis.made to pass about both the sides and the top and bottom of said oven, the end or partof the oven most remote from the fire chamber, being heated as well as the part adjacent to said fire chamber. p The accompanying plates of drawings represent my improvements.

In Plate- 1, Figure 1, is a elevation of my improved stove.

front or end Fig. 2 is a plan or top view of the same. In Plate 2, Fig. 3, is a transverse verticalsection taken;

in the plane of. the line A-B, Fig. 2,Plate 1, and Fi 4 is a longitudinal vertical section taken in the plane of the line C in said I Fig. 2.

a a a in Fig. 4 Plate 2 represents the fire chamber with a swinging grate 6 band having directly under it the ash pit 0 0, cl and 6 being respectively thefire chamber and ash pitoloors. At the top, of one ofthe sides of the fire chamber, is an aperture through c which the smoke, &o., passes intothe smoke pipe f, while the fireis being kindled, said aperture, at. other times, being closed bythe sliding damper g, shown in Fig. t Plate 2. In the topplate h l of the stove, is formed the aperture or; spaced, to be used for boiling purposes. Immediately behind the fire chamber and between the partition/hi0 on the back of said fire chamber andthe rear end plate Z Z of the stove, is placed the oven m m m 'm, said partition in k which extends a little way overthe top of the oven, forming the back of the oven, and said ovenjbea ing supported byflanges formed on the back of the partition and by a flange on the rear end plate Z 'Z. In this end plate Z Z isthe oven door 11. n. I l c .7: 7c, is prevented from passing immediately across the top of the oven out through the smoke pipe, by the partition 1), extending in a diagonal direction from the top of the oven to the top of the chamber which leads to the smoke pipe, as shown in Fig. 3

Plate 2.

A curved partition w extends from the top plate h h to the top of the oven, as shown in Fig. 3 Plate-2 and by dotted lines in Fig. 2 Plate 1, and abuts against the partition is is. From the bottom plate 39 p, of the stove, extends the long straight partition as w to the bottom of the oven, running nearly the whole length of said oven; "The course of the heat, &c., is shown by the arrows in the drawi gs.

As the heat comes up from the fuel into the chamber 0 0 on the top of the oven, it is prevented from passing directly into the chamber t t on the side of the oven, by the curved partition W, before referred to, by which means it is made to traverse the whole top of the oven, before it. can pass into the chambert 25, thus keeping the part of the oven remote from the fire chamber hot, as wellas the part adjacent; to said fire chamber. It then passesidown the passage t 25 into the passage 9 9 under the oven, and is made-"topassto the end of the oven which is farthest from the fire chamber, before .it

tition w m; From the passage q 9 it passes up through the passage 11. u and out through the smoke pipe, thus forming a current of heat entirely'around the top, bottom and both sides of the oven. a

c Having thus describedmy improvements in parlor cookingstoves, I shall state my claim as follows.

. What I claim as my invention and desire ing stove, by which the heat, smoke, &c., is first made to pass over the top of the oven and then dOWn the passage formed between the front side plate and the side of the oven, a'cross the bottom of the oven up through the passage formed between the rear side plate and the other side of the oven, and finally out through the smoke pipe; the heat, &c., being made to pass to the part of the oven most remote from the fire chamber, by the N. A. BOYNTON.
