COOK!NCl-STOVE..l
SPECIFICATION forming part of Letters Patent No. 425,320, dated April 8, 1890.
Application filed January 30. 1890. Serial No. 338,606. (No model.)
T all whom t 77mg/ concern:
Be it known that I, JAMES S. HARKINS, of Minneapolis, in the count-y of Hennepin and State of Minnesota, have invented certain linprovemen ts in Oooking-Stoves, of which the following is a specification.
My invention relates particularly to that class of cooking-stoves wherein coal is used as the fuel, although wood may be used, if de sired; and its object is to provide a stove which, by the combustion of its several parts, will utilize to the greatest extent the heat generated by the combustion of the fuel, and at the same time make the combustion as perfeet as possible; also, to provide means for carrying ott' the more 0r less offensive odor arising from cooking done on or by the stove. l accomplish this much-desired object by means of the Construction and combination hereinafter described, and more particularly pointed out in the claims.
In the accompanying drawings, forming a part of this specification, Figure 1 is a longitudinal vertical section of a stove embodying my improvements. Fig. 2 is a plan view with the top of the stove removed. Fig. 3 is a vertical section of the same on line of Fig. 1. Fig. i is a sectional plan View of the same on line fg] y of Fig. 1.
In the drawings, 2 represents the oven; 3, the ash-box; 4, the fire-pot, consisting of the two parts e and 5, 4 representing the fuel-res ervoir and 5 the combuStien-chamber immediately above. The whole is inclosed by the exterior walls (S, 7, 8, and 9, being the top, rear, bottom, and front, respectively, of the stove. The oven 2 is supported upon the divisionplates and 11 above the bottom 8, and separated from the rear wall 7 by the plate 12, thereby forming a flue for the heated air down back of the oven and toward the front under the oven around the plate, returning` up the back of the oven on the other side of the plate l2, and thence out the smoke-flue l5 through the opening 1G, formed by the top and sides of the stove, the plate 17, and the top of the Oven. Between the plate 17 and the top end the front- 9 and opening into the ash-box 3 is the draft-opening 22, having suitable means for its regulation.
Directly in front of the oven and between 55 it and the fronti) of the stove is arranged the fire-pot, the fuel-reservoir 4 of which consists of the grate 10, supported upon suitable bearings in the circular walls 20 near the bottom,
the flaring walls 2O terminating at the top in 6o the horizontal flange or projection 2l, which rests upon and is supported by the exterior walls of the stove and the front wall of the oven. By the use of the flange 21 the air entering the stove through the ash-box is forced 65 to find exit through the grate 19, the flange preventing it going around. Above the fuelreservoir e is the combustion-chamber 5, its walls 23 also preferably constructed circular and flaring, the bottom coming down to within 7o a short distance of the top of the reservoir 4:, forming a space all around having a direct communication with the main ilue 25 over the top of the oven.
Around the coinbustion-chamber 5 and out.- 7 5 side the wall 23 is arranged a second wall 27, forming with the wall a hollow chamber 2S entirely around the combustion-chamber 5. This chamberis preferably provided with the pipe 2S), so arranged that its outer and 8o open end 30, which is preferably enlarged or flaring, is near the upper surface of the stove and near as possible to the portion thereof where the main part of the cooking 1s done:
From the chamber 2S are a series of holes 31 S5 2S into the combustion-chamber 5, and finally 9o into the llue 25 by first passing down out of the combustioil-chamber 5 and ont through the fuel between the combustion-chamber and the fuel-reservoir.- The top of the combustion-chamber 5 is preferably provided 95 with an opening to receive the fuel-chute 3G, having the door or lid 37 arranged in the top 6 of the stove, closing the opening in the chute. It. is also provided with the draftopenings 3S, allowing a direct draft through Ico the fuehreservoir 4 and combustion-chamber 5 into the flue 25. Over these draft-openings 38 is arranged the sliding plate 39, adapted to open and close said openings.
' On each side'of the combustion-chamber 5, and extending from the flange 2l to the under side of the top plate G of the stove, are provided the partition-plates 41, the object of which is to prevent the heated air which naturally arises in front of the combustionchamber from passing around it to the rear, and thence into the flue 25, and compelling it to rise in front of the plate 41 until it is above the combustion-chamber, when it is directed toward the central opening between the top ends of the plates 4l, bringing it directly under the griddles 44 in the top 6, used for cooking purposes. In front of the combustion-chainber are arranged the V-shaped plates 47, forming, with the side plates 41, flues for directing the current of heated air against the griddle holes 44, as hereinbefore stated.
Encircling the entire combustioireliainber and outside the division- plates 41 and 47, and extending from the flange 21 to near the top of the combustion-chamber, is the incasingwall 50, the object of which is to direct the heated air coming through the combusti0nchamber and fuel directly against the upper part of the stove, Where it can be utilized, and keeping it away from in contact with the side walls of the stove, where more or less would be radiated and lost as far as its usefulness in cooking` is concerned.
The operation is as followsz' Fuel being placed in the reservoir 4 and kindled in the usual manner, the direct- draft dampers 39 and 18 are opened and air isadmitted through the draft-opening 22 inthe front of the stove. The course of the air is then first into the ash-box, thence through the grate 19 to the fuel, the gases and unconsumed products of combustion, as well as heated air, finding exit out of the combustion chamber through the draftopenings 38, thence through lthe iiue 25, draftopening 18, and out into the smoke-flue 15. lVhen the fire is suffi ciently started, the dam pers 39 Aand 18 are closed, thereby forcing thev gases and unconsumed products of combustion down through the fuel between the combustionchamber 5 and the fuel-reservoir 4 and out into the flue 25, thence around the oven and out through the smoke-flue 15. The
the chamber 28 through the series of holes 32 into the combustionchamber 5, and thence through the fuel, while the heated air rising on the outside of the wall tends to draw it through the series of openin gs 31 in the outer wall 27, and thence direct to the flue 25. The air passing through the pipe 29 into the combustion-chamberfurnishes a sufficient amount of oxygen to complete the perfect combustion of the gases which arise from the partial cornbustion made by uniting with the air from below the grate 19.
I claim as my inventionl. The combination, in a cooking-stove, of a fire-pot comprising the fuel-reservoir 4, with the iiange 21, and the combustion-chamber 5, with its walls 23 and 27, forming a hollow chamber 28 aroundit, the pipe 29, leading into said chamber 28, the series of openings 3l and 32 in the walls 23 and 27, the draft.
2. The combination, in a cooking-stove, of the fuel-reservoir 4, flange 21, combustionchamber 5, so arranged that the bottom of its walls 23 and 27 will be above the lian ge 21, leaving a space between, walls 23 and 27, with chamber 28 between, pipe 29, leading from near the top of the stove into said chamber 28, openings 31.and 32 in the walls 27 and 23. respectively, fuel-chute 3G, draft- openings 22, 38, and 18, oven 2, and flues 25 and 15, substantially as described.
3. The combination, in a cooking-stove, of the fuel-reservoir 4, combustion -ehamber 5 above said reservoir, having walls 23 and 27, forming the chamber 28, the series of openings 31 and 32 in the walls 23 and 27, the inclosingwall 50, division-plates 4l and 47, draft-openings 22, flues 25 and 15, and oven 2, substantially as described, and for the purpose specified.
In testimony whereof I have hereunto set my hand this 21st day of January, 1890.
