3 Claims.
This invention relates to gas burners and it has to do particularly with burners for gas ranges.
Gas ranges usually employ several burners which are sometimes referred to as top burners, these being adjacent a top portion or supporting surface of the range so that cooking vessels are supported above the burners. These burners are each supplied with the fuel comprising a mixture of air and gas by a mixing tube or venturi and in some cases it is desirable to have the mixing tubes in a plane below the burners. In this situation, the fuel passing to a burner through a mixing tube is caused to be turned so as to flow in an upward direction at about the time the gas enters the burner.
The automatic igniting means for the burners usually embodies a pilot flame positioned more or less centrally of several burners with flash tubes extending from the pilot flame to the burners, there being one flash tube for each burner. When gas is supplied to a burner, some of the gas is caused to flow through the flash tube where it is ignited at the end of the flash tube adjacent the pilot flame. This results in a flash-back or sort of explosion and ignites the gas issuing from the ports of theburner.
In order to furnish gas to the flash tube for each burner, there is provided a fitting commonly referred to as a tip which is engaged in a charging port inthe burner. The tip conducts the gas from the port and directs it into the lflash tube. A more or less standard type of tip is an element or fitting with a passage therein which is angular in form so that gas enters the same in an upward direction and is turned through substantially 90 and directed into the flash tube which extends substantially horizontally. Now, a diiculty arises when this sort of a lighter arrangement is used with a gas burner which is positioned above the mixer tube, particularly Where the port for receiving the gas which is to cause the ignition is positioned in alignment with the upwardly extending part or upwardly opening mixer tube. In this case the gas is flowing directly into the port and due to its velocity as well as pressure/too much gas will enter with the result that an improper action is provided. The gas may even blow the pilot flame to such an extent that it may be extinguished. Yet, it is desirable to use a standard size tip so that the tips can be manufactured Awith uniformity, and can be interchangeable with all types of burners.
The present invention provides an improved arrangement whereby the charging port is protube with a spreader or baille for controlling the flow of gas into the burner and make for a uniform flame condition throughout the circumference of the burner. Otherwise, an excess of gas mayv flow through the burner ports at a position immediately over the mixer tubewhile a lower volume of gas would be furnished the burner ports remote from the end of the mixer tube. The invention is disclosed in the accompanying drawing:
Fig. 1 is a general view showing two burners -of a gas range and indicating the lighter arrangement.
Fig. 2 is an enlarged View, partially in plan, of a burner, with some parts cut away to show interior structure.
Fig. 3 is a view partially in side elevation with parts cut away and parts shown in section.
Fig. 4 is a cross sectional View taken substantially on line 4-4 of Fig. 2 showing the burner and lighter arrangement.
As illustrated in Fig. 1, a frame structure of a gas range is shown at I, and it is provided with a top surface or plate 2 which lies over several burners, but which has openings 3 therein to expose the same. Two burners are shown, each generally indicated at 5, and each is supplied with gas through the means of a controlling valve 6 while the primary air for the mixture may be regulated by adjustable air control element 1. Extending from the air control element is the so-called mixer tube or Venturi 8.
The burner structure, as shown in Figs. 2, 3 and 4, comprise a body portion I2 with a circular channel I3 therein. The body may rest upon'a support I4 and one side of the body portion has a projecting flange like arrangement I5 for attachment to a, corresponding flange I6 at the upwardly opening end of the mixer tube 8. This may be accomplished by means of screws Il. A burner cap 20 seats upon the burner body. This cap structure may be somewhat in the form of a ring so as t'o cover the channel I3 and provided with a spoked center having a screw 2I which is threaded into a cross bar 22 of the burner body, the cross bar providing openings 23 for secondary air. The cap is provided with a multiplicity of grooves 25 to provide ports when the cap is seated on the body, so that gas issues from the ports to support the gas flames. The inner peripheral portion of the cap may be provided with a suitable number ofports 26 also for the issuance of flame supporting gas.
Now, it will be .noted that thei upwardly opening end of the mixer 'tube is positioned adjacent one side of the channel I3 as will be appreciated by reference to Fig. 2 where the passage formed by the mixer tube and by the burner body is indicated at 30. Accordingly, some of the burner ports which are immediately adjacent and above the passage 30 are liable to receive an excess supply of gas Vwhile those more remote therefrom may receive less. To meet this situation, the burner body isprovided with a baille or separator 3| which is positioned in substantial alignment and above' the passage 30. This baille may Y -be a strut-like element formed integrally with the burner body andas shown in Fig. 3 has oppositely inclined surfaces 32 and 33.' The upwardly iiowing gas strikes these surfaces-and is iiame 4l in a housingor guard 42, there being a iiash tube for eachburner as shown in Fig. 1. The other end of the flash tube is provided with extending arms 43 secured in which is the tip. This tip may comprisea block of metalhaving a body portion 44 and a tapered extension 45 with an angular opening or passage 48 therethrough. The tapered portion 45 is 4designed to fit into a charging port 41 in the burner body. When gas is supplied to the burner, some gas iiows through the charging port through the passage 46 and is directed to flow through the flash tube 40. This gas is ignited by the iiame 4l. There is a resultant flash-back which then ignites the gas issuing from theports 25 which may, in turn, ignite the gas issuing from ports 26.
Now, it will be observed that the charging port 41 is in direct alignment with the gas iiow passage 3B and due to the fact that the charging port 41 directly faces the on-coming velocity of the` gas, there would normally be too 4great a iiow of gas through the ash tube, which might blow the pilot iiame 4l from its source and extinguish it. Yet, it is desirable to use a tip of standard size so that the portion 45 need not be varied and so that the tips maybe used with all kinds vof burners.` To take care of this-situ- 4 partially across said passageway and defining an enclosing wall of said passageway, gas igniting means including a tip for'a iiash tube, said wall section having a charging port extending` trans- ,v'ersely therethrough for receiving the tip and for supplying gas thereto, said wall section extending generally transversely of the axis of said passageway so that the charging port is in substantially direct alignment with'the direction of iiow of the gas, whereby iiow of gas into the charging port is iniiuenced by both pressure and velocity, and means at the inlet end of said charging port providing an ensmalled metering n port for the gas passing from said passageway to the tip to reduce the volume of gas passing to the tip to substantially oiset the tendency of increased iiow which would normally pass therethroughdue to the velocity.
2. In gas burning equipment, a burner body l,having ports for the issuance of iiame supporte ing gas 'and having a downwardly opening inlet passage, a mixer tube for conducting gas to the burner and having an upwardly opening outlet passage communicating with theinlet passage of the burner, the burner body having a wall section extending partially across the outlet passage of the mixer tube substantially horizontally and defining an upper enclosing wall for part of the tube, gas igniting means including a tip for a iiash tube, said wall section having a chargingf port extending transversely therethrough for receiving the tip, whereby the ilow oi gas into the charging port tends to be increased due to the iniiuence of velocity of iiow, the burner body having an ensmalled metering port in the inlet end of the charging port of such a size as to reduce the iow of gas passing into the charging port to substantially oiset the influence of velocity.
3. A gas burner comprising a body having ports in its upper portion for the issuance of iiame ation, the burner is provided with a metering port which is ensmalled relative to the port 41 to cut down the supply of gas entering the charging port. As shown in Fig. 3, this is provided by forming the charging port 41 only partially through the material of the body of the burner and by providing the ensmalled metering port 48 with the charging port 41 and which serves to reduce the gas supplied for ignition purposes. This is provided without requiring any additional manufacturing operations and the size of the port 48 may be selected to provide the desired igniting function under conditions encountered. lAccordingly, a standard tip may be used in this type of construction which would otherwise require different structures and manufacture conditions for tips and the charging port therefor.
