2 Claims. (Cl. 126-273) The present invention relates to improvements in combination ranges and more particularly refers to a combined coal and gas range in which the inconveniences and dangers attendant upon former constructions are largely eliminated, and in which ideal baking conditions will prevail.
Heretofore it has been the practice to construct two-fuel combination range ovens by placing a burner in the bottom of the oven and inserting a baille plate above the burner to spread the heat from the gas burner in the oven chamber. It proved diicult to obtain ideal baking conditions with this arrangement because it was impossible to establish an even heat circulation, which is essential to ideal oven baking conditions. The
" arrangement referred to involves a number of l to the burner and for carrying 01T the gases generated in the oven. Without a provision of this kind it was impossible to establish any circulation, for the reason that the confined heat in the oven, without any outlet, would reflect upon the burning `of the gas, causing floating, which became a source of great danger.
A further objection to the damper arrangement was that quite frequently the operator would neglect to open the Vent damper and explosion occurred, which became very annoying to say nothing about the danger of burning the operator of the range. While it is true that most damper arrangements of this kind were created for the very purpose of being fool-proof, nevertheless very few of them worked out in actual practice.
An object of the invention is to correct the deficiencies above referred to and to provide an improved range having adequate oven heat circulation and outlet.
Another object of the invention is to provide, in a combination range, a combined bottom oven burner and overhead broiler burner, so coordinated as to gas supply that only one of the burners may be supplied with fuel at a time.
With the foregoing and other objects in view, the invention will be more fully described hereinafter and more particularly pointed out in the appended claims.
In the drawings, in which like reference numerals refer to like or corresponding part through the several views.
Figure 1 is a vertical section taken longitudinally through a combinationrange constructed according to the present invention.
Fig. 2 is a vertical transverse section taken on the line 2 2 in Fig. 1 and Fig. 3 is a'horizontal sectional view taken on the line 3 3, also in Fig. 1. Y.
Referring more particularlyl to the drawings, designates generally the casing of the improved combination range, having at one end thereof the rebox 11 disposed above the ashpit 12. These parts will be accompanied by the usual features, such as the grate 13 etc., and above such rebox may be disposed stove lids or plates 14 set in the stove top 15.
In this stove top 15 are also set a number of grills 16 cooperating with gas burners 17 in connection with a suitable source of gas 'supply and having the usual controlling gas cocks. These gas burners 17 are preferably set off in a compartment lseparated by a casing 19 from the top flues of the oven 20 which has the usual front door 21 shown in Fig. 2.
Within the oven 20 is disposed a lower or bottom gas burner 22, and an upper or broiler burner 23, these burners also being in connection with an appropriate source of gas supply and having an improved control device as hereinafter more fully referred to.
The stove bottom is indicated at 24 and the oven bottom at 25, being spaced above the stove bottom 24 to provide the bottom horizontal ues 26 and 27 disposed at opposite sides of the partition or baille 28. For convenience in illustration, particularly of Figs. l and 2, this bale plate 28 is shown as extended in front of the burner stem 29 but as a matter of practice, the partition will preferably terminate at or about said burner stem 29 .in order to provide adequate sweep of the warm air and heated products from one flue 26 to the opposite flue 27 at the forward part of the stove.
Now the oven bottom is preferably supported upon ledges 30 carried by one end wall 10 of the stove and an intermediate separating wall 31 disposed between the oven and the firebox 11 and ashpit l2. Upon the legdes are also supported inverted U-shaped or channel spacing members 32, which cooperate with the lugs 33 upstanding from the oven bottom 25 to receive therebetween the lower edges of the oven liner plate 34. These plates 34 may be made from sheet iron or other desired material and they are spaced from the walls 10 and 31 whereby to provide passages or ues 35 between these parts, which passages are open at their upper ends into the head space of the oven 20. The liner plates 34 are corrugated or otherwise formed to provide ledges 36 for selectively receiving the baie plate 37 having the marginal openings 38 therein.
In the top plate or oven roof 39 at one side, namely at the side adjacent the firebox 11 are provided openings 40,'placing-the oven base in communication with a substantially horizontal and transversely extending ilue 41 opening at the rear of the stove unobstructedly to the stack as indicated in Fig. 3. This flue 41 may have the triangular cross section shown in Fig. 1, such flue being comprised between the perforated portion of the oven top 39, the extended upper portion 42 of the vertical partition wall 31 and a plate 43 which extends diagonally across from the upper end of the wall 42 to the oven roof 39 adjacent the openings 40.
The stack connection is shown at 44 in Figs. 2 and 3 and as before stated the ilue 41 opens directly to this stack connection 44 and is in communication with the same at all times irrespective of the action of the damper 45, which is intended to control the flow of the heated products from the iirebox 11 to and through the oven ues or directly to the stack connection 44.
The upper portion of the iirebox 11 communicates, through an opening 46, with the upper iiues 47 and 48 between the oven roof 39 and the casing 19. These flues 4'7 and 48 may be disposed side by side or the flue 47 may be stepped above. the flue 48. The damper 45 closes the rear end of' the flue 47, or when open, permits the direct outflow of the heated products from the rebox 11 to the stack connection 44.
As shown in Fig. 3, the horizontal oven flue 48 communicates at its rear end with the down-take flue 49, and this down-take flue connects at its lower end with the rear end of the lower horizontal oven flue 26. The rear end of the other lower horizontal oven flue 27 communicates with the ,lower end of the up-take flue 50, which, as shown in Fig. 3, is separated from the down-take ilue 49 by a partition 51. The rear wall of the oven is 'shown at 52 in Fig; 2 as being spaced from the outer stove rear wall 53. The vertical flues 49 and 50 are provided between these walls 52 and 53. The vertical partition 51 may be a continuation of the horizontal partition 28, if desired.
As shown in Fig. 3, one end of the damper 45 is provided with a trunnion 54 journaled in an opening in the partition plate 51. The damper 45 is provided with a crank 55 inserted through an opening in the damper operating bar 56 which projects up through the stove top 15 and is accessible for operation` above the stove.
In Fig. 1 the broiler burner 23 and the lower burner 22 are shown as supplied with gas through branch pipes 57 and 58 having connection with a feeder pipe 59 from the manifold 60. Where the feeder pipe 59 joins with the branch pipes 57 and 58 is located a three-way cock 61 which will l' operate to shut oif the gas from both burners 22 and 23` or to supply the gas to one or the other burner but not to both burners at the same time. In the operation of the stove, the articles to be bakedmay be placed upon the baffle plate 3'7 andthis baille plate may be placed at various elevations in the oven, the same being slidable in and out on the ledges 36 provided by the liner plates 34. In this way the article to be baked may be placed in a proper location relative to the burners 22 and 23. The heat rising from the lower burner 22 will be intercepted by the baille plate 37 and deflected laterally of the baille plate 37. This deflected heat will partially pass through the openings 38 in the baille plate which is spaced above the base of the oven and partially through openings 62 in the lower portions of theA liner plates 34 and into the air spaces 35 provided between the liner plates and the outer walls 10 and 31, by which the heat will also ascend into the head space of the oven; whence it may seek exit out through the openings 40 in the oven roof 39 and into the horizontal flue 41. As heretofore explained the flue 41 will carry the gases -and heat unobstructedly to the stack connection pipe outlet.
44 at the rear. of the stove. In this way I obtain an adequate circulation of heat within the oven and an adequate yet restricted outlet of the same, whereby to maintain proper oven temperature but at the same time avoid the dangers incident to prior construction. The openings 40 and flue 41 afford a Ventilating system which will carry oif the fumes from the oven to the smoke This flue 41 has the advantage of doing away with any burner arrangement, is always open, will create a perfect circulation of heat in the oven and will be free from soot from the coal fire, .because it is in no way connected with the coal flues of the range.
The three-way cock 61 is a factor of safety, feeding as it does both the broiler and oven burners 23 and 22, but this gas cock will not permit the use of top and bottom burners at the same time.
Where the coal fire is used, the heat will flow out from the rebox through the opening 46 and into the top oven flue 47, thence into the companion top oven flue 48, down the vertical ilue 49 to a point below the oven bottom 25, thence forwardly through the lower oven flue 26 and in front of the partition or baille 28, into the opposite lower oven ue 2'?, by which the heat and hot products are carried rearwardly to the other vertical flue 50. This flue 50 communicates back of the damper 45 with the stack connection 44. Y
