MODE 0F APPLYING HEAT 'IO COOKING-STOVES.

Specification forming part of Letters Patent No. 505, dated December '7, 1887; Reissued November 14, 1848, No. 90.

F0 all 'wh-0m it may concer/n.'

Be it known that I, JONATHAN GAYLORD HA'ri-niwAY, of Painesville, in the county of Geauga and State of Ohio, have invented a new and Improved Principle of Applying Heat to Cooking-Stoves; I do hereby declare that the following is a full and exact description.

The advantages to be derived from my 1mprovement are that a great quantity of baking, roasting, &c., may be done in a stove occupying comparatively a small space, that the ovens may be more o-r less heated without augmenting or diminishing the quantity o tire; that when heated to the required temperature, the heat may be for a long time retained in the iiues, rendering only asmall quantity of fuel necessary for heating a room and doing the cooking. l

To enable others skilled in the art to make use of my invention, I will proceed to describe its construction and operation.

I construct my stove in any shape size or height required, with three apartments, one above the other (see Figures 1 and 2.) The two lower apartments (marked in Fig. 2, a) are for thepurposes of baking and roasting-the upper apartment (b, Fig. 2) constitutes the ire room, the top of which is perforated with holes of any shape or size to admit oi' boilers. Between the back of the stove, and the backs of the reroom and upper oven, is a plate (c) running parallel with the back which divides the space (which should be from 2 to 6 inches according to the size of the stove) into two iiues, this dividing plate rests on the back of the lower oven which terminates the forward perpendicular flue (d Fig. 2). The bottom of the upper oven and ltop of the lower one, are placed at suiiicient distance apart to forni a horizontal flue (f) between the ovens, which is connected with fines which completely surround the lower oven, the front flue (g) formed by a space between the lower front of the stove, and the front of the oven. The bottom flue (la.) is formed by a like space between the bottom of the stove and the oven bottom. The back flue (i) by a like space between the back of the stove and back of the lower oven running to the pipe. The back of the iire room (called the tire plate) has an aperture (k) of sufficient capacity to admit of all the smoke to pass. The plate (c) which forms ,a division of the upper iiues, is made suiiiciently wide to come as high as the top of the aperture in the fire back, and on the to-p of said plate rests a plate or damper (Z) of sufficient dimensions to close either of the lues. This damper may be moved (by a rod (m) which protrudes through a hole in the back of the stove) so as to cover either flue. When this damper is drawn so as to clo-se the back iiue the smoke will pass through the aperture ga) 1n re back and ascend immediately to t e pipe, which is situated on the top of the stove over the flues. When the damper is shoved so as to close the 4top of the front Hue, the smoke and heat pass through the aperture (7c) in the fire back, thence down the back of the upper oven, through the horizontal iiue between the ovens, down the front and under the bottom thence enters the back flue and ascends to the pipe. When the ovens have acquired a suiicient temperature of heat, the damper may -be drawn to close the back flue, which stops the circulation of air and confines the heat in the lues around the ovens, thereby keeping an even and proper heat for baking and roasting.

The same principle may be applied to a stove with but one oven (which oven may be divided by horizontal and other plates into apartments) as represented in Figs. 3, 4, and 5. The fire place (marked a: in Fig. 3) forming the upper apartment, and the lower apartment the oven. There are two backs and two bottoms, placed at suiiicient dlstance apart so as to leave a space behind and under the oven (0 c c) which space is divided into'ues by means of plates (d in Figs. 4 and 5) running down the center of the back and under the oven. (e) is made through the inside back (Fig. 5) which ad mits the smoke and heat to pass into the iue (f) thence itdescends -to the flue (g Fig.V 4) passes forward around the end of the dividing plate into (7L) and ascends by i'lue (i Fig. 5) to the pipe. The flues may also be constructed as represented in Figs. 6 and 7 in which case the space in the back and bottom may be divided in to 3 lues by plates (a a a a Figs. 6 and 7) running down the back and under the oven. The inside back `has 2 apertures b Fig. 6) through the two pass around the ends of the division plates (a a) into the Center bottom Hue (e) and pass to the pipe up the center back Hue, (Fig. 6, f)-

Apertures, (which when the stove is in operation are kept Closed) are formed in -the front of the stove opposite each Hue, for the purpose of letting in cold air in oase that the oven or ovens are too Inuoh heated, and through Which the soot may he removed in case of their becoming foul. The front of the stove is represented in Fig. 8 and the apertures marked (a a a).

When the stove is constructed With one oven, the Hues may he formed into two by a plate running down the back and under the oven bottom, to Within about six inches of the front; in Which oase the smoke and heated air may be forced down on one side thereof7 and under the oven to the front, pass around the division plate into the opposite Hue, thro-ugh which they ascend t0 the pipe.

What I Claim as my invention and desire to secure by Letters Patent is- The constructing of a Cooking stove with the lire place in the upper compartment thereof7 and the oven o-r ovens beneath the fire, and having the Hues arranged and reg ulated in the manner herein set forth.

To the omvm'noner o Patente.'

The petition of examen Garneau Hamann?, formerly of Painesville, Ohio now of Lancaster, Pennsylvania, an Tnonaa Dimm, of Bufalo, Erie county, and State of New Yor respectfull reprecents that the said JONATHAN man Hamwar obtained Letters Patent on the 7th day of December 1837, for a new and useful mode of applying heat to a cookin stove, which Letters Patent issued out o the Patent Oce at Washi n, and the said 'Ifnoaus I. Dimmi by assignment from the said Eatentee became the owner of a portion of t e said ptitent right, that they have reason to believe that through inadvertencez and mistake, the claim made in the specliication of said Letters Patent, is too broad, including that of which the slild Jonathan Gaylord Hathaway was not e first inventor. Your petitioners therefore hereby enter their disclaimer to that Bart of the claim in the aforesaid specification, which is represented in Fi 4- and 5 in the sectional drawings, and w ich is described in the following words:

There are two backs and two bottoms fiiad at suicient distance apart, so as to eave a since behin' d,' and under the oven (c c c) w 'ch space is divided into dues by means of plates (d, Figs. 4 and 5) running down the center -o the back, and under the oven (e) an aperture is made the inside back in (Fig. 5), which admits the smoke and heat to pass into the flue (f), thence, it descends to the ue (9?l Fig. 4 passes forward around the end of t e dividm plate into (h) and ascend by the flue (agFxg. 5) to the pipe.

In another part of the specication the sume application of heat through inadvertence is refeated in the following words which is a so hereby disclaimed:

Patented Dee-f7, 1837.

When the stove is constructed with one oven the dues may be formed into two by a plate running down the back and under the oven bottom to withinV about six inches of the front in which case the smokeand' heated air ma be forced down one side thereof and un er the oven to the front, pass around the division late into the opposite flue through whic they ascend to the pipe, which disclaimer is to operate to the extent of the interest in said Letters Patent vested in your petitioners, who have aid ten dollars into the Treasury of the mted States a able to the uirements of the act of (iongress in thatrse made and provided;

and we do hereby declare that the building of the fire over the oven was not intended to be claimed excepting in combination with the dues constructed and arranged as described in the specification of the Letters Patent in referred to' and any other acceptation thereof is hereby disclaimed.

Dated at Buffalo 21st Sept. 1844.
