COMBINED SELF-FEEDING COOKING AND HEATING STOVE.

- SPECIFICATION forming part of Letters Patent No. 334,971, dated January 26, 1886.

(No model.)

To all whom it may concern.-

Be it known that I, JOHN H. NEVINS, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin, in the State of Minnesota, have invented certain new and useful Improvements in Combined Self-Feeding Cooking and Heating Stoves, of which the following specification is a full, clear, and exact description, reference being also had to the accompanying drawings, in which- Figure 1 isa sectional front elevation on the line w 00 of Fig. 2. Fig. 2 is a sectional side elevation on the line to w of Fig. 3. Fig. 3 is a crosssectional view on the line 3 1 of Fig.2.

This invention relates to combined self-feed ing cooking and heating stoves; and it consists in the construction and arrangement of parts, substantially as hereinafter shown and de scribed, and specifically defined by the claim.

In the drawings, A represents the fire-pot, A the shell or casing, A the ash-pit or base, and A the magazine or cylinder in which the stock of coal is placed to supply the fire, all these parts being arranged in the ordinary manner of a self-feeding heating-stove.

B is the grate, which is constructed and mounted in the ordinary manner, except that it is formed with a convex upper side or made crowning or domeshaped on its upper side, so that when shaken or revolved the ashes and cinders will be crowded out toward the outer edge and fall down into the ash-pit.

shell or casin g, G, and inner shell or oven prop-.

er, 0 leaving a hot-air space, a, surrounding it on three sides, and a hot-air chamber, (L between the oven C and the firepot A, while the doors 0 O",leading to its interior,are arranged on the two remaining sides.

On a line level with the top of the firepot A,and surrounding the shell A ,is a flat plate, D, having griddles or pot-holes b, the shell A running down from this plate D to the bottom plate of the base, as shown.

D is another plate parallel with and a short distance below the plate D, and forming a diaphragm connection between the fire-pot A and shell A leaving a space between it and A wall, d, shuts off all comp except through the space between the plates D D and walls d d in a similar manner, by connecting the top of the fire-pot with theplate D, shut off all communication. between the space between the plates D D and the fire-pot, except at the front part, e,where the walls (Z d are turned off in opposite directions, as shown at d (1 By these arrangements all the smoke, gas, &c., must pass over the front of the firepot through the space e,and thence to either side between the plates D D and into the hot-air space a.

I claim a great advantage in bringing the heat to the front before it passes to the sides, as l. thereby not only secure all the benefit of the radiation, as in an ordinary heating-stove, but in addition utilize the heat for cooking, 820. It also enables me to burn the fuel more slowly, and thereby gain a saving in quantity of fuel burned.

g g are two dampers arranged to close the space between the ends of the walls d d and the shell A of the stove, so as to turn the draft to whichever side it may be required.

If the dampers are set as shown in Fig. 3,

then all the smoke, gas, and their accompanying heat will be turned into and pass beneath the plate D on the left of the fire-pot, so that the kettles or other utensils in the pot-holes on that side will receive the benefit of all the heat, and by reversing the positions of thedampers the heat may be turned in the opposite direction. Then by opening both dampers the heat will be equal on both sides of the fire-pot. .By this simple arrangement the heat may be completely and easily controlled and turned entirely beneath either set of potholes desired, or equally beneath both.

m m are two small pipes connecting the fire-pot A with the outside air through the lower side of the shell A", through which a supply of air may be fed to the fire, in addition to that passingin the ordinary manner up through the grate. These pipes m m will be provided. with coversn n so. that the air can beshutofi from them, when desired.

Under some circumstances it may be desirable'to feed the fire with air entirely through these tubes and dispense with the usual draftopenings in the ash-pit doors. By the useof these pipes m m ,'I am enabled to greatly increase the draft without opening the ash-pit door. Ordinarily, if additional draft is required, the ash-pit door must be partially or wholly opened,which generally permits ashes and dust to, escape, besides imparting to the stove an untidy appearance. By the use of the pipes 111/ mi, however, it is never necessary to open the ash-pit door, except to remove the ash-pan, 8tc.,w.hich only occurs generally once everytwenty-four hours.

E is the smoke and gas flue, leading fromthe top of the oven-casing up through a I water-reservoir, F.

G. isasliding damper arranged to open and closecommunication between the hot-airspace a and.- theflue E, and G is another similar damper. arranged to open communication between the hot-air space a! and the hot-air space a! beneath the oven. These dampers G G are shown made in a registefliorm, but may bemade in any other suitable man= ner. 1 If theupper damper be opened and the lower. damper be closed the heat, gas, &c.,will passdirectly into the flue E and not heat the oven, and then if the upper damper be closed andthe lower one opened the heat, &c.,will

all pass around and heat the oven before it escapes by the flue. I claim a great advantage by this arrangement, whereby I amenabled to turn the heat, 850., down beneath the oven 0 first, and thence over the top, instead of first over the top and thence beneath the bottom, as in the ordinary cooking-stove, as I thereby secure the greatest amount of heat at the lower part of the oven,,where it is most required for cooking.

one side with the space between plates D D,

and saidspace communicating on the opposite side of the fire pot with the fluespace on one side of the oven, and dampers located in said flue-space above and below this point of connection, substantially as described.

In testimony whereof I have hereunto set-my hand inpresence of two subscribing witnesses.

JOHN H. NEVINS.
