GAS BURNER.
Application filed March 29, 1927. Serial No. 179,316.
This invention relates to gas burners and more particularly to a gas burner for use with either high or low gravity gas alone or both simultaneously.
An important object of the invention is to produce a burner of this character which, in all phases of operation, will provide a Hat neutral flame.
A further object of the invention is to provide means for preventing back firing in the burner caused by the introduction there to of too lean a mixture.
A further and more specific object of the invention is to provide an automatic valve for cutting off the effect of a flue draft, to which such burners are always subjected when the burner is operating under low pressures, or is turned down to such an extent that the incoming gas will not of its own velocity suffice to prevent the intaking of an excessive amount of air for mixture with the gas by the suction created by the flue draft.
These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a side elevation of a burner constructed in accordance with my invention;
Figure 2 is an end elevation thereof;
Figure 3 is an enlarged sectional view through the burner end;
Figure 4: is an enlarged sectional view through the gas drums and air intake device;
Figure 5 is an end elevation of the gate structure employed for controlling the mixture;
Figure 6 is an enlarged sectional view on the line 66 of Figure 4.
Referring now more particularly to the drawings, the numeral 10 generally designates a gas drum having an inlet 11 in one side wall thereof. 12 designates a smaller gas drum having an inlet 13 at. one end thereof, the drum 12 being inserted into that end of the drum 10 adjacent which the inlet 11 is exposed and being sealed to this drum, as at 14C. The inner end wall of the drum 10 is provided with an axial outlet nozzle 15 and is surrounded by a concyclic group of nozzles, of which alternate nozzles 16 are carried by the wall and communicate withqthe interior of the drum 1() and theremaining nozzles, indicated at 17, extend through'the end wall of the drum 1 0 and are secured to the end wall 18 of the drum 12 and communicate with the interior of this last named drum.
The outer drum 12 slidably fits the interior of an air inlet tube 19 and issecured in adjusted positions in said tube by a set screw 20. This air inlet tube has secured thereto the smaller end of a conical flange 21, which surrounds the tube and has its open larger end directed toward that end of the tube, in which the drum 12 is inserted. The wall of the tube 19 within the drum is formed with air inlet openings 22 and slidable upon the exterior of the tube is a collar 23 having a flange 24 which, by its coaction with the flange 21, determinesthe amount of air, which may enterthrough the openings 22. The collar 23 may be secured in adjusted positions by a set screw 25.
The numeral 26 generally designates a burner which is in the form of a flat casing having its outlet end open, as at 27, and its opposite end closed, as indicated at 28. The upper wall 29 of the chamber is transversely curved with cambered face downwardly disposed. A mixing chamber 30 communicates with the burner 26 through the bottom thereof adjacent the closed end wall 28 and this mixing chamber has a sleeve-like extension 31 in which the end of the tube 19 engages.
Slidable in the extension 31, inwardly of the inner end of the tube 19, is a tube 32, which is held in adjustable position by a set-screw 33. The inner end of this tube has pivoted thereto at the upper end thereof a gate 84 which normally moves by gravity to close the end of this tube and accordingly to close communication between the mixing chamber 30 and tube 19. The end wall of the tube 32 with which the gate 34 coacts is preferably provided with inwardly extending lugs 35, which will prevent this gate from sticking or jamming in the mouth of the tube in event it engages therein, due to looseness of the pivotal connection 36. The preferred connection between the tube and gate is provided by forming a pair of ears 36 upon the end of the tube adapted to receive therebetween an ear 37 formed on the gate. These ears are apertured for the passage of a pin 38, which is held in position by struckup flanges 39 on the gate, Which oppose the ends of the pin.
In operation, the velocity of the incoming gas causes air to be drawn in through the openings :22 and forces the gate 34 open. The
gas and air pass the gate and enter the mixing chamber 30, Where they are mixed and passed to the burner. The fiue draft deflected by the ordinary flue (not herein disclosed) assists in opening the gate 34. When the pressure from the drums drops or is cut down, the gate- 34 partially closes, thus assisting in cutting down the proportion of air to the gas, Which enters the chamber 30. The construction 6II1- ployed in the burner eliminates the natural tendency of the flame to fan since it increases the amount of gas fed at the edges of the burner.
It will be obvious that the construction hereinbefore set forth is capable of a certain range or change and modification Without opposite end of the tube discharges, a second tube-inserted in the lastn-amed endof the first named tube, and a gate hinged to the end of the last named tube adjacent the mixing chamber andnormally, closing by gravity,the Walls ofthe last named tube a'tisaid end'having inwardly extending lugs against which the gate engages when in closed position.
2. A gas burner comprising a shallow casinghaving-one'end;thereof open, the upper Wall of the casing being transversely arcuately curved '\v-itl1-the chan'iber downwardly disposed, the casing; having anintake open ing adjacent its closed-end; i
3. In gas inlet device for gasburners, concentric drums of different diameters having inlets at corresponding ends thereof, the inlet ends oiisaid drumsbeing sealed to one 'an other, the inner drum being the shorter whereby the opposite end walls ot said-drums are spaced froinone another, nozzles carried& by the end wall'of and communicatingwith the interior of the outer drumand othernozzles carried by the endvvallot" and communicating with the interior of the inner drum and having their ends extended through openings in the end Wall of the outer drum.
In testimony whereof I hereunto afiix my sign ature.
