g a I ATTORNEY JOHN W.- IDUPUY'; OF PITTSBURG-Idf, PENNSYLVANIA.
STOVE.
Application filed June 18, 1915. Serial No. 34,780.
To all whom it may concern Be it known that 1, JOHN DUPUY, a
I citizen of the United States, and residing in the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Stoves, of which the following is a specification. 4
My invention comprises certain new and. useful improvements in cooking stoves or ranges.
' to show the parts more clearly; Fig. 2 is a- The objects in view are as follows: An improved combination coal and gas stove which ma'y be instantaneously changed from one fuel to the other without the use of tools and whose efficiency and utility is not im paired by its adaptation to double use. The :rovisi'on of a four-way circulation of heat about the oven Walls, thus avoiding the formation of a superheated portion which would result in burning out portions of the stove structure and'also in burning the contents of the oven, and also avoiding improperly heated portions of the oven walls.
In the accompanying drawings, which are intended merely as illustrative of a practical embodiment of my invention and not to limit the scope thereof to the structure shown, Figure 1 is a perspective of a stove embodying my improvements, the front wall being broken away and the doors omitted vertical sectionof the same along the line I]II in Fig. 1, and Fig. 3 is a broken horizontal section of said stove in the plane of the line III-J11 in Fig. 2. 1
The following is a detailed description of the drawings.
A is the oven to the left of which is the coal or solid fuel fire-box B, and to the right the gas burner box C. If desired the arrangen'ent may be reversed. but usually the fire box is arranged at the left of the oven and I have adopted such arrangement as preferable. In accordance with this arrangement 1 term the flue, hereafter described, interposed between the fire box and the oven as the -left flue, whilethe vertical flue at the opposite side .of the oven will be termed the right flue for purposes of identification, and not as indicating their exact or invariable location.
D is the top plate or lid platform of the stove of the usual construction.
The fire box B is provided with a convenient type of coal grate 2 below which is Specification of Letters Patent. I
Patented Oct. 12, 19115.
. the ash-pit. 3. The front of the firebox port-ion is closed by the usual doors, not shown. The oven A 1s, inclosed by the top oven-"- plate 4, theback wall 5 of the stove, side oven- plates 6 and 7, bottom oven-plate 8 and the fpont oven do0r,'not shown, one of whose hinge-sockets is indicated at 9.
Beneath the oven is the bottom flue a, formed by the oven-plate 8, the bottom flue plate 10 and the front and back walls of the stove, 'At the gas side of the oven is a ver-.
ti'c al flue b, which for convenience I term the fright flue, formed by the oven-.plate 7, the exterior wall 11 of the stove and the front and back; walls of the stove. Said flue communl-cates at its bottom with the bottom flue a, and at its top with the top-flue 0', formed between the top oven-plate 4 and the top plate D and the front and rear walls of the stove. T-he upper end of the right flue 7) is stepped, or inclined inwardly to give room for the inner end of the gasburner box 0 and to permit the top plate D of the stove to extend in the same plane.
d is the left flue formed between the side oven-plate 6', the fire-box wall 12 and the front and rear walls of the stove. its bottom the flue d communicates for its entire width with the bottom flue'a and at its upper end said flue (Z communicates with the top flue 0 through a port in the top ovenplate 4. The side oven-plate 6 is inclined inwardly at its top ,to join the top ovenplate 4 and said latter plate is extended over the upper end of the. flue d to join the vertical wall 12. Above said flue, J said plate 4. is offset vertically as at 13 to form a seat or recess and said ofi'set portion is provided with a. transverse port 14: which forms the upper mouth of the, flue d. To the left of said port, said plate 4 is provided with a tgransverse upwardly extending rib 15 forming a shoulder where the plate 4 merges into the vertical Wall 12.
1G is a transverse damper pivotally supported in the front and rear walls of the stove and when horizontal or downiclosing the port 14 and thus sealing the upper end of the flue (Z and when vertical or up, uncovering the port 14 but closing the passage between the fire box B and the top flue c. When down said damper 'seats' in the offset 13.
17 is the removable fire back which is supported in the fire-ooX by means of its upper horizontal portion hooking over the shoulder and restin against the rib 15 while its depending portion extends inwardly and impinges at its foot against the vertical wall 12. thus forming a triangularair space 18.
E is the escape flue to the upper end of which the stove-pipe leading to the chimney is to be attached. Said flue extends downwardly along the exterior face of the rear wall 5 of the stove and communicates with the rear of the bottom flue a. by means of an open port 19.
20 is a port leading from the top flue 0 into the upper portion of the flue E.
21 is a damper pivotally supported in the flue E and when vertical or up closing the port 20 and thus shutting ofl direct connection between the flue 0 and the escape flue E, but when down? or horizontal, opening the. port 20 but shutting off the lower portion of the flue E and thus preventing the escape of the products of combustion through the port 19.
A. horizontal flue 22 at the. back of the stove connects the gas burner box (I with the flue E above the damper 21.
The bottom flue plate 10 is provided with a central transverse, rectangular opening'23 which extends substantially from front to rear of the oven and over the greater part of the width thereof, and is provided with underflanged edges 2i to support in place to close said opening the division flue plate 25 which is lifter socket 26 for ease in removing or putting the same in place in said aperture 23.
27 is a gas burner, shown as an H-burner,-
mounted justunder the opening and connected to the gas-supply pipe F. The burner may be inserted and installed and the (livision flue pl ate put in place and removed through the clean-out door 28 leading into the bottom flue 29 is a perforated bottom plate under the burner 27 to supply air to the same.
30 is the bottom flue strip within the bottom flue a loading at an angle From the 'rear wall 5 to the right of the port 19 to the edge of the opening 2?). and tending to throw the heat desi'tem'ling the line I) toward the front oi? the flue (7 before reaching the outlet port 19.
The operation of the invention is as follows: lVlien coal is being used and cooking .is to be done on the top oi? the stove only, the division flue plate 25 is installed to close the aperture 23 in the bottom flue plate 10 and the dan'ipers 1.6 and 21 are both turned down so that the products of combustion will flow out through the top flue c and the port 20 to the flue E. \Vhen coal is being used and the oven is to be heated, the damper 16 is turned down and the damper 21 up. The products oi combustion now flow out of the tire-box B into the top flue (1, down the right flue Z; into the bottom flue a preferably provided with a wherein they are thrown over the entire extent of said flue by the flue strip 29 and then escape through the port 19 to the flue E. The heat from fire-back 17 radiates across the air space 18 through the wall 12 into the flue (Z whose upper end is now closed by the damper '16, preventing the upward escape of the heat. lhe heat is thus forced downwardly through. the flu" 0? into the bottom flue a. It is thus seen that all four sides of the oven are uniformly heated by the coal fire. In some of the types of coal stoves now in use, the'portion of the oven wall directly next to the fire back is overheated, causing the food in the oven to be scorched while the lower left front part of the bottom oven plate has been an unevenly heated zone. The fire back and the adjacent portions of the stove become burned out owing to the unradiated excess heat. These abuses are all avoided by my improvements for all four sides of the oven are equally heated and no concentration of excess heat can occur. The air space 18 prevents overheating of the adjacent wall 12. The arrangement of a down flue between the oven and the fire-box and fireback, com municating at the bottom with the bottom flue under the oven may be applied with equal success to purely coal or solid fuel stoves where the interchangeable gas prin ciple is not used, and the advantages above recited'will be fully realized. \Vhen gas is to be used to heat the oven, the division flue plate 25 is removed exposing the aperture 23 in the bottom flue plateand the gas turned on in the burner 27 and lighted through the clean-out door 28. The damper 1G is now raised to open the port ll and to cutoff communication between the top flue and the fire-box. The damper 21 is turned down to open the port 20 and close the lower end of the escape flue E. The fumes will now rise from the burner 27' into the bottom flue a and up on the either side of the oven through left and right flues d and I) to the top fine 0, passing over the top of the oven and thence out of the port 20 to the escape flue E. It is evident that the oven is thus thoroughly heated on all four sides, giving a uniform, even baking or cooking heat.
For the sake of illustration I have shown the course of the heat currents when coal is being used to heat the oven by means oi short arrows, while the course of the heat currents when gas is being used for that purpose is indicated by the long arrows.
l have shown in the drawings a stove having its flue and oven walls of sheet steel, but it will be understood that my invention is equally applicable to cast iron stoves.
The advantages of my improved stove are self-evident and important. It fulfils every requirement of two stoves, one for gas and the other for coal or other solid fuel. It has an even and uniform circulation around the oven. It may be instantaneously changed from coal to gas, and vice versa, without the use of tools. The left flue which is back of the fire-box takes the heat off from the fireback and leads the same down the oven wall and into the bottom flue, prolonging the life of the fire back and evenly distributing its heat. The three way flue system heretofore used produces uneven heated zones, which are avoided by my four way system.
The construction of the stove is inexpensive, yet the distribution of the heat is such that the life of the stove is preserved and prolonged.
IV hat I desire to claim is 1. In a combination stove adapted for use with solid or gaseous fuel, an oven, a top fll extending over the top of the oven, a bottoi flue extending beneath said oven, verticaal flues at either side of said oven connecting said top and bottom flues, a chimney flue adapted to be connected. to either said top or said bottom flue, a fire box on the opposite side of one of said vertical flues from said oven, a gas burner mounted beneath said bottom flue and adapted to discharge its products of combustion into said bottom-flue beneath said oven, and.means for shutting off either said fire box or saidlast named vertical flue from said top flue. 2.
