. Description.
The present invention is an improvement upon the burner described in my Patent No. 1,47 8,383 of December 25, 1928. By the improvement of the present invention gas may be burned down to as low a pressure as one-twentieth of one foot per minute. The details of the invention comprise a cylindrical burner body 10 having an outwardly flared outer chamber 11- and inner chamber 12 separated therefrom by an annular flange 13 formed adjacent the tip of: an air nozzle 14 disposed within the inner cham-' ber 12.
The end of the burner body opposite the chamber 11 is closed by a flange 15 formed on the air nozzle 14 and the entire air nozzle structure is moved longitudinally within the burner body by pressure of the cap nut 16 threaded over the end thereof. Gas is admitted to the chamber 12 through the intake port 17 formed through the burner body and leakage from the chamber 12 is prevented by means of a pair of washers 18 and 19. The Washer 18 is annular and is seated in a groove formed in the flange 13 for bearing engagement against an internal annular shoulder 20 formed at the inner end of the outer chamber 11. The Washer 19 is annular and wedge shape in cross section being disposed on the periphery of the flange 15 for wedging engagement between the flange and the adjacent end of the burner body. It will be apparent that as the cap nut 16 is tightened the air nozzle will be forced forwardly in the burner body binding the washer 18 against the shoulder 20 wiile the cap nut binds the washer 19 Serial No. 53,233..
against the end of the burner body, thereby providing against any escape of gas from the chamber 12 except through the spaced annular series of gas discharge orifices 21 disposed through the flange 13 and parallel with the tube of the nozzle 14.
The outer end of the air nozzle 14 is adapted for connection with an air conduit (not shown), while the inner end extending within the chamber 11 is closed as at 22, air being delivered from the nozzle through the spaced series of ports 23 extending laterally through the wall of the nozzle to eflect an air discharge Within the chamber 11 at a right angle across the gas discharge through the orifices 21.
By reason of the fact that the air and gas streams converge at a right angle and into an expanding chamber, a maximum mixing is obtained with consequent maximum combustion. The discharge of air through the ports 23 impinges against the inclined walls of the chamber 11 and assists in delivery from. the burner.
In the modified form of air nozzle tip illustrated in Figure 3, the nozzle 14 is provided with a closed end 22 as in the preferred form, having the flange 13, gas orifices 21 and washer 18 formed thereon. However, in this modified form of tip the air (ill discharge ports 24 are disposed at. an 'outwardly inclined angle approximating 45 de grees through the wall of the nozzle as clearly illustrated.
Claims.
chamber, and means formed in said air nozzle for effectin angular crossed discharge of air and gas into said outer chamber against the expanding walls thereof.
2. A gas burner comprising an open ended body having an outer expansion chamber and an inner chamber formed therein, said body being provided through the side thereof with a gas inlet communicating With said inner chamber, an air nozzle having a closed end mounted in said body and extending longitudinally through one end thereof into said expansion chamber, annular flanges formed on said nozzle for closing the opposite ends of said inner chamber, one of said flanges having discharge orifices arranged therethrough in parallel relation to said nozzle for discharge of gas from said inner chamber into said expansion chamber, said air nozzle being provided at its closed end with air discharge ports formed therethrough for discharging air at an angle across said gas discharge orifices, and Within said expansion chamber.
3. A gas burner comprising a'body having an inner gas chamber and an outer expansion chamber, an air nozzle insertable through one end of said body and extending through said gas chamber, said nozzle having a closed inner end disposed Within said expansion chamber, spaced annular iangcs integrally formed on said air nozzle for closing the ends of said gas chamber, one oi said flanges being provided with transversely extending gas discharge orifices opening into said expansion chamber, said air nozzle adjacent its closed end being provided with a plurality of radial air ports for discharging into said expansion chamber across said gas discharge orifices.
