This-invention relates to{improvements in oven burners 'and' the manner of installing the same.

in conjunction with gas stoves used in apart s, ment houses of the high-oven type, sometimes *5 called'felevated oven, and the low oven'type,

sometimes called four hole cooker, or threehole cooker, as well'as all other baking and broiling ovens for gas stoves which must be placed in small space and, therefore, especially designed and adapted for apartment house kitchenettesl The invention has for some of: its objects the provision of a'burner for the ovens or" gas stoves or" the indicated character, whereby to produce a better and improved distribution of the, heat um amount of air to reach the flae of each pcrthole to improve combustion and thus increasethe thermal efficiency of-the burner and oven; to construct the burner so that the gas connectionsior the burner may be made interchangeable for either the right-hand side or the left-hand side of i the oven, and also interchangeable for either the front part or rear part of the oven beforethe gasportholes are drilled in the burner; and to provide means' co nnected with theburner in 7 such a manner that the gas feed pipe will be a concealed, and further enabling the association oisthe control valve for the oven burner with the valves for the cooking burners so that itmay i be easily located and be conveniently accessible. The nature of the invention and its distinguisln ing features and advantages will appear when the following specification is read in connection with the accompanying drawing, in which- I Figure 1 is a fragmentarysection of a gas stove of .the ele vated ovenrtype, selected to illustrate a burner installed in the oven thereof, in accordance with the invention;

Figure 2"is a perspective view of theburner detached, thesame being shown inverted? of Figure 2., i

' The gas stove 10, as illustrated in Figure 1, in-

cludes an elevated oven 11- and a gas manifold 12, to whichthe usual control valves are directly connectedat the front of the stove at the base thereof .'-The oven of thetype loi stove shown is subdivided by a removable bottom oven plate in the baking oven section, which is shown at 13. The tins or pans and the like which contain the goods to be baked or roasted are placed onshelves or racks in the upper section of the oven, above the removable bottom oven plate.

most space of we the oven serves to receive the a relatively wide broiler pan.

Figure 3 is a transverse section'on the line 3 3' as at 23.

11 consist of a gas. feed The lowergoods, tolbe broiled and toasted. It is in the lowermost space or, in other words, the bottom of the oven inwhich'the burner' l i otsthe, present invention is'positioned; It is to be understood that the gas connections to the burner 14- rnay be positioned at the left or the right, or :60, toward the front or rear of the oven,'wherever it is most convenient to make the gas connection, also in orderto havethe benefit of as much space as pos'siblejand thereby permit the use'of B5- The burner leis of a single strand type, substantially of rectangular shape. The burner consists of 'a hollow elongated element closed at the ends and having flat top and bottom walls 15 and 16, respectively, which are joined at the opposite side by relatively angularly disposed walls 17' may be provided two such ears on one end and -76 one each on theopposite end for attaching, securing or suspending the burner from brackets or the like on the'side walls of the oven; Each of the ears may be'scored so that those notwanted may be broken off; The burner in the present instance is shown positioned in theoven urea tending lengthwise between the sides thereof. The ears on the ends of the burner are each attached as at 19 to a bracketao secured to the related side'wall'o'f the oven. I

The burner is, provided with portholes, 21 for theoutlet of streams or jets of gas." The portholes occur in the burner so as to direct the streams or jets of gas laterally downward for best results. The portholes, therefore will be drilled in those walls 17 whichwhen the burner is in position will face downwardly. This drill-- ing is done after the position of the burneris determinedp-Any arrangement of portholes in I H a each angularly' disposed .wall 1'? may be provided, l

and in the instant case there is one row in each of the downwardlyfacing' walls 17; "By provide ing the burner with top and bottom fiat walls having flat outer surfaces, the burner may repose on .a fiat support, whilethe portholes arebeing mll drilled, which is a vdistinct advantage. The burner is provided with laterally extending gas inlet means 22 on one end, the same being in the form of a tubular extension which is tapped v i I V 05 The gasconnections leading from the manifold pipe 2 1 whichv extends rearwardly, then upwardly behind the backwall 25, then forwardly through the wall 25am then upwardly into the oven at one side wherein it isii l fi fitted to an air regulator 26 connected by a gooseneck 27 in threading engagement with the tapped end 23 of the inlet 22 of the burner. It will be apparent that the feed pipe 24 will be practically concealed, The feed pipe has connected therein 7 a control valve 28 to control the flow of gas to the burner. The valve 28 is arranged adjacent the manifold in line with the other valves for the cooking burners and, therefore, will be conveniently accessible. 2

From the foregoing it'will be apparent that there has been described a gas stove equipped with an oven burner to which gas is fed from underneath the oven at one side affording a maximum of space for a relativelylarge broiler pan; that by providing the goose-neck it is possible to have the air regulator 26 in a convenient position for adjusting it to regulate the supply of air entering the burner through the bottom of the oven; that the gas to the burner may be controlled from the front of the stove below the oven en- 7 abling a person standing at the front of the stove to turn on the gas and instantly ignite it as it issues from the burner; that the flat top and bottom of the burner permits spreading out the burner to such an extent as to separate the two rows of gas flames to a maximum distance, thereby improving the distribution of heat in the gas oven; and that by reason of the construction of the burner 14 a maximum amount of air may reach the flame of each porthole improving the combustion.

We claim: 2 An oven gas burner consisting of a hollow elongated burner element comprising fiat top and bottom walls joined by relatively angularly disposed side walls, each of certain of said side walls being apertured to discharge the gas laterally downward, at opposite sides of the burner, said element having laterally extending gas inlet means-on one end thereof, and means integral with the element for attaching it.
