Matthews, Cleveland, Ohio Application September 6, 1934, Serial No. 742,906 . ‘ 1 Claim. ’ (Cl. 126-39) This invention relates to a complete assembly and overhang the center header ll whereby to for the top burners of a gas stove or a range. conduct gas from the burners to. the constant It is a‘primary object of the invention to obtain a compact assembly of this kind obviating the ‘pilot 33. Each burner is provided with a small injection orifice 34 that receives a mixture of gas _ as soon as the burner is turned on, which gas an 5 use of a front manifold and a series of gas cocks - extending therealong. A further object is to ?ows along'the ?ash tube .to the. constant pilot 33. There it ignites and ?ashes back to ignite‘ gas issuing from the gas outlet port 35 of each provide the burner lighter as an integral part of the assembly rather than as an accessory to be added thereto. It further provides for the use 10 of four top burners identical in construction so as to be, with their Bunsen tubes, completely interchangeable. The two gas cocks controlling _ An air opening is provided in the-bottom of 10 each Bunsen tube 23, as is shown at 31 on burner' I2. The size of this air outlet is adjusted by a shutter plate 38 pivoted as at 39 to the bottom of each Bunsen tube. Obviously variation in the the top burners _are likewise interchangeable. The ?ash tubes to the lighter are integral with 15 the Bunsen tubes of the burners. The central pilot light is formed integrally with the header supplying gas to the burners. In the drawing: size of the opening 31 varies the quantity of air - 15 to be mixed with the gas injected from the spuds. An arouate opening 36 is provided in the end of- each Bunsen tube, that extends around the. bottom of‘thev same to air opening 31, as seen on burner l2 in Fig. 1. The shutter 38 may then be opened and the Bunsen tubes‘dropped over its ' Fig. 1 is a plan view of the assembly. _ _ Fig. 2 is a vertical section on line 2-\-2 of Fig. 1.

This intake Ill leads 2‘ to a central header H from which gas is dis , tributed to the several_bumers“l2,_ l3, l4, and I5. To opposite sides of this header I I are secured gas cocks i6 and ll of the_dual type such as are shown in our‘copending application #735,686, so filed July 17, 1934. Valve I6‘ is secured to header burner. After this, the shutter may be adjusted. H by an inlet projection l8 thereon engaging front manifold with its awkward construction. The header ‘II is then secured by any suitablev means to this pipe Ill. Valves l6, l1 and 26 are with the header by such means as screw threads. Two outlets l9 and 20 lead to spuds~2l and 22 re The outer end of the burner may be supported in any desired manner. The assembly is installed as follows: Pipe III is led in from some point, preferably the rear of the stove, to the center of the ‘top burner section. It will be seen that this eliminates piping around the stove to a front manifold, and eliminates the spectively that distribute into the Bunsen tubes then fastened to header ll . It will be seen that thus is provided a rigid center structure. With controls gas cook l6 and, as disclosed in the valves I6 and I1 interchangeable, each may be installed on either side of the header. The burn above mentioned copending application, selec tively distributes gas to burners l2 and I 5. Gas ers are then dropped on- with the cut-outs 36 cock I‘! is in all respects identical with gas cock dropping over the spuds to support the \ZBunsen tube ends of the burners.
