(Cl. 126—-39) 1 The invention relates to gaseous fuel cook stoves or ranges of the type comprising oven and cooking top sections disposed side by side with the top section equipped with a cover which forms a lateral extension of the oven section so as to provide a continuous flat top surface at an ele ‘ vation convenient for working purposes. Stoves of this character are commonly made in thirty 2 have shown in the drawing and will herein de scribe in detail the preferred embodiment, but it is to be understood that I do not thereby intend to limit the invention to the speci?c form disclosed, but intend to cover all modi?cations and alter native constructions falling within the spirit and scope of the invention as expressed in the ap pended claims. For purposes of illustration, the invention has six inch and forty inch widths, the former being most popular because of space limitations in small 10 been shown as incorporated in a gaseous fuel cookstove having a generally rectangular body kitchens and also for economy in cost of manu with an oven section 5 at one end and a cooking facture.

In a gaseous fuel cookstove of the table type in combination, a pair of sheet metal shells as» sembled in nested relation with an interposed of the oven. layer of heat insulating material, said shells being mounted at one end of the stove to de?ne an oven, The outer shell 2!, as herein shown, is formed each of said shells having top and side panels in a plurality of separate parts including side 10 connected by corner portions, the top panel of panels 30 and 3| and a top panel 32. The top the outer shell forming a ?xed working top, panel 32 forms the working top 1 of the stove means on the side panels of the inner shell for and together with the panel 26 of the inner shell supporting a plurality of utensil racks, a cooking forms the top wall of the oven compartment. top at the other end of the stove, depressed Similarly, the side panels of the two shells form 15 burner bowls formed in said cooking top and the opposite side walls of the oven compartment. partially overlying said oven, burners mounted vIn order that the cooking top may overlap the below said bowls, a removable cover having oven section and thus permit both of these units marginal edge flanges resting upon said cooking to be made of optimum width, the inner insu top, said cooking top being depressed below said lated side wall 2| of the oven section is connected working top to permit said cover to lie flush there to the top wall by a corner portion 24 having a with, the corner portions of said shells adjacent rabbet 34 therein forming a seat for the marginal said cooking top being shaped to provide clearance edge of the cooking top panel l0.

In the present said cooking top'and connected with said top instance the rabbet 34 is formed by shaping the panel by a curved section, an inner sheet metal upper edge portion of the shell 21 so as to form shell having top and side panels connected by a an upright ?ange 35 to which the depending convexly curved corner portion spaced from the marginal ?ange of the ?xed top panel 32 is suit— ably secured. It will be observed that the fixed top wall of the oven section is made of substantially greater thickness than the side walls. It is therefore corresponding parts of said outer shell, the side panel of said inner shell having means for sup porting an oven rack, a layer of heat insulating ’ heavily insulated so as to maintain the working I top surface 7 relatively cool when the oven is in operation. At the same time, it permits of the formation of a rabbet of substantial depth to re ceive not only the flanged marginal edge portion of the cooking top panel IE) but the correspond ing edge of the cover I ‘i. In other words, the rab bet may be made of a depth corresponding to the combined thickness of the cooking top panel and its cover so that the top face of the latter is positioned coplanar with and forms an exten- ~ sion of the ?xed working surface ‘I of the oven section. While a rabbet of substantial depth has the effect of reducing the thickness of the corner portion 24, it is to be observed that this occurs material disposed in the space between, said inner and outer shells, a sheet metal plate form ing the cooking top of the stove, a depressed burner bowl formed in said plate and positioned ‘ to extend over the corner portion of said outer shell, and a removable cover for said cooking top, said plate being positioned below saidwork ing top to permit said cover when closed to lie flush therewith, the curvature of the corner por tions of said shells being such as to provide clear ance for said burner bowl in the depressed posi tion of said member. 3.
