GAS BURNER.

Application led November 24, 1924. Serial No. 751,806.

4 To aZZ whom 7'1 may concern.'

Bc it known that we,.JAY M; AXTELL and Fimo G. VON HOFEN, citizens of the United States, residing at Fort VVOrth, in the county of Tarrant and State of Texas,have in-` .gas so that uniform pressure is maintained for all the jets. The object is to providegas burners for general heating purposes and particularly to burners in u'hichfthe circulation of the vgas will exert substantially the same pressure at all points in the burners so that the burners will furnish heat of substantiallyfthe same temperature throughout the heated zone. Other objects and advantages will be fully explained inthefollowing description and the invention will be more particularly pointed out in the claims.

Reference is/had to the laccompanying drawings which form a part vof this application. v v

Fig. 1 is a lan view of the improved burner. Fig. 2 1s a horizontal section of the same.' Fig. 3 is 'a plan view of abut-ner which ,is a slight 'variatibn of the burner previously shown. l Similar characters of reference are used to indicate the same parts throughout the several views.l

-The burner is preferably made of a single casting having a general quadrangular shape with a central membercommunicat- ,ing with the end members. The receiving end 1 is provided with alboss 2 into which is screwed anozzle 3 forl suppl ing gas to the burner. is threaded interiorly `to receive the end of a suppl pipe 5. The end member 1 has an interior y projecting boss 6 which forms a socket for the inner end of the nozzle 3 and also as a gas directing'means for the return currents of gas. Gas is fed through the nozzle into a central member 7 whlch is connected with'and communicates with the end vmember 8. The end member'8 is connected with and communicates with the side members 9 and 10 which also communicate with the end member v1. The members 1, 7, 8, 9. and 10 all have passage for zas and may be The outer end 4 o the nozzle tubular in form. Openings 11 are made at the corners of the burner in line with the members 9 and 10 for` convenience in lthe manufacture ofthe burners. These openings are to be closed with am7 suitable plugs. The burner is provided with any' convenient or required number of burner nozzles 12 to be distributed according to the type of heater in which the burner is to be used.

In operation the gas enters the central member 7 and takes the direction of the arrow heads. At the closed end 8, the gas is divided for distribution and circulation through the lateral members 9 and 10. The

end member 8 is provided with Aan inwardly A projecting divider 13 Yfor dividing the gas.

The gas, in passing through 'the conducting members 7, 8, 9. and 10 is fed to the nozzles 12. When the gas reaches the member 1 on the return trip, it is deflected bythe defiector 6 into the member The gas in passing through the nozzle 3 tendsvto create a suction vwhich draws the gas from the members 9 and 10 and(drives the same through the member In this lnanner, the gas pressure is maintained substantially uniforntxin all -the members 1,- 7,'8, 9, and '10,

In the form of burner shown in Fig. 3, the lateral lmembers 14 and 15 are substantially circular with no end members. At the side diametrically opposite the supply nozzle 4, a divider 16 serves to direct the passing gas into the members 14 and 15. 4The members l14 and 15 have inwardly projecting circulating vmembers 17 which are provided with battles 18. The gas will be compelled to take the direction of the arrow heads. The circulation of gas in this form of burner is similar to' the circulation of the gas in the form shown in Figs. 1 and 2.

What we claim, is,-

1. A gas burnercomprising distributing p members consistin` of a central receivin member, end mem ers connected therewit and communicatin vtherewith and said end members having dividers, and lateral-members communicating with said end members, and a receiving nozzle for directing gas through said central member, said distributing members having burner nozzles.

2. A gas burner com rising circulatinV members provided with urner nozzles and consisting of a central receiving4 member, a receiving end member providedv with an 1nwardly projecting divider for directing gas to said central member, an end member con- ,los

- nected with said central memberat the discharge end and provided with an inwardly gas into said central member.

3. A gas burner com rlsing circulating members provided with burner nozzles and consisting of a central circulating member having a receiving end and a discharge end, lateral circulating members on opposite sides of said central member and 'connected with and communicating with both ends of said central member, a-divider delector at the discharge end of said central member for directing gas into said lateral members, and a nozzle for supplying gas from'the supply source to said central member and for aiding in directing gas from said lateral, members into the receiving end of said central member.

In testimony whereof, We set 'our hands, this 19th day of November, 1924.

JAY M. AXTELL. FRED G. VON HOFEN.
