GAS' BURNER Filed March, 1931 ATTORNEY Patented 7, 193e ,EDWIN D. vAIJAJIIS, E BZTTSBURGH, PENNSYLVANIA eas suenan Application. med March G, w31. Serial llo. 520,571.

M invention relates to heaters and more particularly to gas burners. v An object of my invention is to provide a continuously operative automatic means operatively associated with an extended gas burner to ensure the quick and smooth ignition oi a plurality of gas dames located non- -gas-igniting distances apart. l

l Another object of my invention is to provide a spreader dame located between the -matin gas-burner portato edect travel of the dame from one main gas-burner port to the next adjacent one.

. ln practicing my invention, l' provide a gasaleurner manifold having a plurality of sets of substantially-laterally-extending main gas-burner ports, which are spaced relatively' large distances apart, and locate therebetween a spreader-llame auxiliary gas 'burner ort whose flame extends substantiallylongitudinally of the manifold to cause theame from one of the main ports to effeet ignition of the gas issuing from the next main port separated therefrom a large nongas-igniting distance. In the single sheet of drawing, l

YFigured is a view, lmainly in front elevation, of ages-burner room heater in which is in corporated the device embodying my i11- vention,

section, showing more particularly the device embodyingxny invention 1n operation, and, Fig. 3 is a top lan view of a portion of a tion v l have shown, generally only, a portable room beater utilizing s as iuel and embodying a casing l1, w ich may be oi any suitable construction, sine, and shape, and es this casing constitutes no particular part of my present invention, itis not deemed neces sary to describe it in greater detail except .to note that it Iincludes an open front in which are located a plurality of clay, radi? ants l2 of the kind now use'dfin radiant gas heaters. The radiante 12 have each an open yface and are suitably sup orted within the open front casing 'many esired manner.

A gas burner maniold 13 is located below gasburner mani old illustrating my invenu the radiante in substantially horizontal position and is provided with a plurality of sets of main gas-burner por 14, which main p ports extend substantially laterally of the manifold so that the flame of the burning gas issuin from the main ports extends at substantie ly ri ht angles to the. manifold,

as is shown in ig. 2 of the drawing. The main gas-burner ports are located immedi-i ately below the inside of the respective radiants, as is shown more particularly in Fig. 2 of the drawing.

It may be noted further that a plurality of main gas-burners ports 14 are provided in each set located relatively close together in order to provide a plurality of relatively small intense, high and vertical gas flames indicated .at 16, which flames extend into the` lower portion of the respective radiante to heat them and thereby radiate the heat out- 'i0 wardly from the casing. As the thickness of the side walls of the vradiants is relative 1y large and as there are two thicknesses closely adjacent to each other, therewill be a relatively large space between the adjacent v main gas-burner ports of' two sets of main ports.

As it is not considered desirable or per missible to locate one or more of the main 'gas-burner ports'iinmediatel below the side 35. walls of tlie'radiants, the-distance between the spaced sets of main ports is so 'great that ignition yof the gas issuin from one end port in one set, from the burning gas issuing from the end port in the next'adjacent' set 35 will notoccur, or stating itin other words, the distance therebetween is a non-gas-igniting distance. This condition is also aggravated, to some extent, by the fact that the flames 16 extend up into the interior ,of the a@ radiant, and the net result is that one set of main burner ports will not be ignited Jiroin the flames of the next adjacent set of main ports. This condition is a very undesirable one as it prevents travel of the ilar'neiroxn 95 the main gas-burner ports at one end of the manifold to the main gas-burner ports at the other end of the manifold in a smooth and noneexplosive manner. That is, if the set of ports 14 under say .the right hand radiant are 10 dll lit by an operator, the dame will not travel smoothly toward the lett without further manual ignition.

'lin order to edect such dame travel quickly and smoothly, as well as automatically, ll provide auxiliary connector or spread-dame ports 2l between two adjacent sets of main burner ports. The auxiliary ports 2l are ot substantially mushroom shape, the orice therein including a central slot 22 and two circular slightly larger openings 23 and 2t.

' The outer surface of the head oi the auxiliary port is ol substantially arcuate shape, as is shown particularly in Fig. 2 oi the drawing, and the shape -oi the dame issuing therefrom is shown at 26 in F ig. 2 of the draw= ing. llt will be noticed that the shape of the auxiliary port and ofthe slot therein is such as to provide a connector or spreader dame whoseheight lamrjally of the manifold is relatively small, but which is provided with substantially horinontallyl and longitudinaL ly extending spreader dame portions. Such spreader dames have been found to be edective to cause the dame to travel from one set of burner ports to the next adjacent set of main burner ports with great rapidity and certaintys thereby overcoming the tendency toward accumulation of unburned gas in the radiante., when it hasfnot been i nited byv vthe operator all along the maniiol llt may providing high vertical dames, which are spaced apart relatively large distances too at to ensure or edect the ignition ot gas 'issuing from one main port by the burnlng f .gas issuing trom the next adjacent main port.

While l have illustrated and described a particularv device embodying my invention, it is obvious that my invention may be used in other .gas-burner devices embodying an extended gas-hurner manifold.

Various modications may be made in the device embodying my invention without de# parting from the spirit and scope thereof, and l desire therefore that only such limitations shall be placed thereon as are imposed by the prior art or are set forth in the appended claims. 1

l claim as my invention y l'. A gas burner having a plurality of sections of main burner ports provided on the surface thereof with said sections so spaced as to impair dame travel from one section to the next and a spreader dame port disposed in the space between said sections of main burner ports, said spreader port being so constructed as to edectively and automatically ca'rry a Home from one adjacent section of main burner ports to the next.

\ 2. A gas burner comprising agas manifold common to the whole burner having a plurality of spaced sections of main burner ports the-radiants and dame-spreadingports disl' posed between said sections of grouped ports, said llame-spreading ports Libein so posi# tioned and constructed as to `pro ucc a low Wide llame adapted to ignitably connect said sections of grouped ports, whereby when one df said` grouped port sections is'lighted the llame will electively and rapidly spread across the burner.

4. A sectional type gas burner-for radiant heaters comprising a gas manifold havinvfa dat upper surface provided with a plurality of spaced sections and grouped burner ports along the length thereof and a dame tip htted in a port communicating with said manifold in each space between Jthe adjacent ends ci said grouped port sections, each of said tips having a slotted orifice in the top thereof adapted to produce a low wide dame and arranged so as to direct its'dame against the yadj acont sections of grouped ports.

5. A combined elongate burner and manifold for radiant heaters and the like having a plurality of sections of grouped main burner ports arranged in spaced relation along the length of the` burner, the spacing between said sections being such as to permit the lower ends oi. the radiante of the heater being mounted over the grouped burner ports whereby their dames will project into the radiants. and a dame-spreading burner ti mounted in a port provided in the ymanifold in the space between the adjacent ends of the sections oi grouped burner ports, said tip being so positioned 'and constructed as to control the gas dow therefrom in such a way as to insure the llames from one section 'ci grouped burner ports being conducted to the nextvvhen lit.

ln testimony whereof, l have hereunto subscribed my name this 41th day of March, i931.
