where the pressure on :the gas is only sufiicient torassure'j a discharge of gas through the nozzles of the gas distributor but not necessarily sufiih v 'webs FL. The shaft It extends to the right cientfto provide for arotation of the discharging device. '7 V In accordance with the present invention the the spider l, and'has mounted thereon a pulley rotary gas distributor which assuresa uniform distribution of the gas'over substantially the'entire cross-sectional area'of the air stream so that V the resultant flame a the gas and air burn is of uniform. intensity throughout isdriven by an external source of power which may be, for exam- 7 ple, an electric motor connected to the gas distributor or a fan associated with theidistributor anddriven by the passage of-air for combustion through the burner. 7 By the use of an external source oi'power for driving the gas distributor, the r'otation of the distributor isassured independently oi the gas pressure'thereby also assuring a thorough mixing of the gas and air for Other and. further vobjectsand advantages of tion with the accompanying drawings in which- Fig. 1 is a sectional .view
bodyingthe invention, v I Fig. 2 is a s'ectional view'through a modified throughv a device emingsf-ll .a'hollowshaft i2-.x on: the innerror left hollow apertured Tarms Ma; which is securedrto the hub:-of the fan .anditselfjhas a hollow hub V5 with which the hollow shaft lZcommunicatesg. A shaft 16 extends through thehollow shaft l2 and is secured thereto by radially extending beyond the end of a cap I8 which is secured to [9; This pulley is connected by a belt ,to a pulley 2| on a suitable driving motor22. By. this arrangement the fan l3 and gas distributor .14 are positively driven from the motor independently a of the discharge of gas from the distributor, and.
'thus rotation'of the distributor is assured even when the pressure on thegas entering the distributor, is so low that the reaction of the gas on v il) itself to' cause a rotation of the distributor and fan. Passages'i ic in the arms Ma communicate with the hollow hub of the distributor l4 and thereby direct gas to the openings Nib, gaseous the arms Ma of the distributoras it escapes.
