V. S. BECK BURNER Filed Aug. 13, 1931 Aug. 15, 1933.

INI/ENTOR. Ver/700 666/( ATTORNEY.

Patented Aug. l5, 1933 N UNITEDSTA TES PATENT OFFICE t BURNER o o o Vernon s. Beck, wifielaQKasl Application August 13, 1931. SerialNo. 556,754 Y claims (o1. 15g-410s) This invention relates to gas burners and more particularly to those of that character for distributing an air and gas rniXtureto the combus tion zone of a furnace and has for its principal object to provide a simplified burner structure for eliecting more economical use of fuel gas.

Anotherimportant object of the inventionis to provide a primary'air and gas mixture in conjunction with a secondary air supply that is discharged peripherally about the outlet of the primary mixture. Another object of the invention istou provide a burner structure which may be installed through the usual furnace` doors without dismantling the furnace. l

is also an object of the invention to provide a burner whereby a unit frame maybe equipped with various shaped burner headsso that the burner assemblymay conform to and cover substantially the entire areaV of a fire box.

VIn accomplishing these and other objects of the invention, l have provided improved details of structure, the preferred formrof which is illustrated in the accompanying drawing, wherein:

Fig. l is a perspective view of a. burner conn structed in accordance with my invention. p

Fig. 2 is a vertical sectional ViewV through the burner illustrating shape ofthe burner heads; l l'ig. 3 is a side elevational view of the burner, apart of which is shown in section to better illus-V trate the manifold construction which distributes gas to the burner heads. p j

Reierring more in detail `to the drawing: g'

l designates a preferably rectangular shaped franse of suitable dimensions `to enable its installation through. Aone of l the `doors opening into the lire bou ci' a furnace. lThe frame lcomprisesa horizontal plate 2 havingY a vdependingperipheral V flange 3 connecting depending tubular `sockets l located at the corners ofthe plate.

. Supported in the sockets Il are nipples `or pipe i sections 5 forming legs for supporting the `plate to provide. ledges for supporting burner heads 94 later described.

The manifold Vpreferably comprises ka plurality of parallel pipes 11, 12 and 13 extending longitudinally of the rows of openings 6 and having gas orifices 14 aligning axially with each of said openings,

ing lugs 25 which may be formed integral there- `The pipes` 11, 12 and 13 are connected inter` mediate their ends by lateral conduits 15 and` 16 and with acentral supply pipe 1'? through which the gas is supplied tothe manifold. The manifold thus described may be a separate unit and supported by the frame 1 or it maybe formed integrally therewith as illustrated in the drawing Y with the ends of the pipes integral with ears 18` depending from the end flanges 3, as best illustrated in Figs. l and 3, the ends of the pipes being closed byintegral diaphragms 19. Y

The burner heads 9 are here illustrated as oom-` prising rectangular shaped box-like members 20 having parallel side and end wa1ls21 and 22 and having` bottoms 23 connected with tubular leg 70` portions 2i` sleeved inthe collars 7 withmtheir lower ends `supported on the ledges 8 as Villustrated in Figr2. a Y j i u "Theleg portions 24 preferably snugly engage the inner walls of the collars so thatthe frictional contact .will prevent their rotation therein. How-V ever, suitable keys may be provided or the legs and collars may be polygonal in shape. A

Supported within thelegs 24 by suitable spacwith, are4 tubular conduits 26 having smaller diameter than the inner diameter of the legs to form an annular passageway 27 therebetween for passage of secondary air as` later described.

- Formed integrally with the upper ends of the conduits `26 are complementary rectangular shaped box-like portions 28 having side and end walls 29 and 30 spaced from the walls 21 and 22 and which cooperate therewith to form an annular air outlet channel 31 extending along the ,0 periphery of the burner heads.`

Supported within theinner box-like,'portions 28 of each burner head is a rectangular shaped plate 32 extending horizontally in the plane of the upper edges of the walls and which has its peripheral edges spaced inwardly from the inner walls 29 and 3l) to provide a peripheral gas outlet 33. One orYV more tubular conduits may be formed in each of the burner heads having their lower ends communicating with the secondary air passageway Z'Iand their upper ends opening `through the p1ate`32 tovdischarge secondary `air within the `boundary ofthe gassoutlet 33 sothat theg'as `flame.burning above `tlhe'gas outlet `will not be pinched inwardlyby the secondary air 'discharged through the outlet 31.

Spacing lugs 25 may also be used at sufficient intervals to connect the plates 32 with the walls 11D of the head as shown in Fig. 2.

The plates 32 are provided with depending baffles 35 to deflect the gas downwardly from the outlet opening, thereby producing a turbulent or whirling effect of the gas to assure complete mixture and uniform discharge about the periphery of the plates.

The conduits 26 are provided at their inlet ends with venturis 36 so that the gas discharged from the orices 14 draws primary air Vinto the burner head for mixture therewithA and to provide a combustible mixture before it is discharged through the outlet 33.

In order that the burner heads may be positioned to cover the entire area of the re box, the side rows of burner heads are preferably provided with offset leg portions as at 37 so that the heads thereof may be extended outwardly and laterally of the side edges of the supporting frame toward the sides of the re box, the lateral offsets of the legs being of sufficient length and shaped to position the burner heads in correct relation with the walls of a fire box.

vIt is obvious that the burner heads maybe of various shapes and may extend at various angles from a manifold so that when they are assembled, they will conform to the cross sectional area of the fire box, thereby adapting the burner to either round or square fire boxes.

Inl installing a burner constructed and assembled as described, the frame 1 having a desired number of collars or sockets 7 is inserted through a re door of a furnace and supported in level position from the oor of the fire box by the pipe sections 5 which may be cut in suitable lengths to position the frame at the desired height and to level the frame. The fire box may then be closed or bricked in about the frame as in usual installations, to divide it into a lower air intake chamber and an upper combustion chamber. The burner heads may` then be inserted through the fire box opening and installed in each of the collars. In the ordinary rectangular shaped fire box a center row of burner heads will be of substantially T-shape as shown, and the outer` side rows will have the specially formed leg portions to position the burner heads so that they will substantially coverthe width of the box.

The supply pipe 17 is connected to a suitable gas supply which may be controlled by Valves (not shown) so that the gas delivered to the manifold and through the orifices 14 'is discharged in proper amounts to Veach of the burner heads.

The gas streams flowing from the orifices 14 will pass Vacross the space between the manifold and the plates 2 into the venturis, and primary air will be entrained with said streams for mixture in the burner heads. The gas discharging from the venturis 36 mixes with theair and a combustible mixture is formed for discharge through the peripheral gas outlets 33. At the same time, the secondary air is drawn through the annular passageway 27 and discharged through the peripheral outlet 31V, and also through the conduits 34 to contact opposite sidesof the gasflame to aid in the efficient combustion of the gas. f

Attention is also directed to the fact that 4the burner heads are spaced lapart to separate the flames and to provide air passageways therebetween to prevent undue heating of the burner heads and also in some installations the secondary air ports may be dispensed with and the secondary air supplied through the passageways between the burners.

What I claim and desire to secure by Letters Patent is:

1. A burner head including an outer rectangular shaped head member, an inner Vcomplementary shaped head member spaced from the outer head member to form a peripheral air discharge outlet and having a gas and primary air inlet, and a plate member associated with the inner member to effect mixture of the gas and primary air'and to form an outlet for said mixture within the boundary of said air discharge outlet.

.2. A burner head including an outer rectangular shaped head member, an inner complementary shaped head member spaced from the outer head member to form a peripheral air discharge outlet and having a gas and primary air inlet, a plate member associated with the inner member to form a gas outlet within said air discharge outlet and having a depending peripheral lip, an air supply conduit communicating with the outer head member, an inner gas supply conduit communicating with the inner head member, and means for supplying gas to the inner conduit together with primary air for retardation by said lip to effect mixing of said gas and primary air before passage from said gas outlet.
