The present invention has among its objects to provide a gas burner of such formandconstruc: tion that gas may be discharged therefrom in spaced parallel. streams; that upon beingpqsb.

tioned in an air supply conduit: theconduitwill be divided by the burner into a plurality of .parallel passages for the flow of air from the conduit; that the burner may be readily removed from said conduit; that overheating of thefgas supplied to. the burner may be. prevented, and withal toprovide a burner which shall be rela tively simple. in construction and otherwise. well adapted for its intended purpose. T

The various features of novelty and invention will be more fully described in connection with the accompanying drawings forming part of this specification wherein the preferred. formof burn} er construction is shown. and wherein,;

- Referring to Figs. 1 and 6,"nu-meral 10 indi'-' cates a vertical end wall, 11 is a, side wall and 12 the roof of a furnace tobe fired. Indicated at Ais a rectangular air-supply-oonduit' of sub-f stan-tially the same width as the furnace tobe fired, this conduit being shown as iomied-by an: extension of the furnace 'roof 12, and " side walls 13 and 14 and a floor or bottom wall '15. Generally speaking, the arrangementthus fardescribed is similarto thatshown in Fig. 1 of-Pat ent No. 1,900,432.

The burner as a whole is generally indicated at B and is supported on a carriage C supported on transversely extending rails 16, the carriage being below the bottom wall or floor 15 of the conduit A as is clearly shown in Fig. 1. The purpose of the carriage is to permit the burner to be moved laterally out of the conduit for inspection and repairs. A portion of the conduit side wall 13 is supported on the carriage as is clearly shown in Fig. 6 and hence it is a simple matter to withdraw the burner from the conduit as will be readily appreciated. Sand seals 17 form a suitable closure-between the top of the carriage Q aniline nderside o th said floor Asis: clearlyshowndn Fig; 6, the burner com- 7 i s aplu a iwc u ight o s ra d in laterally spaced. relation 'to. form individual .5 passages 20 througlrwhichthe air'irom the conduit A may flow toward the furnace for support ing combustion of the gas discharged from the burner.. TIhesaid bodiesare of va substantial length longitudinallyoi the conduitA (Fig. 1) 1 0 and; are of substantiallythe 1 same height as the cpnduiugand;as..will1more .fully appear herein- I iisi erleeh rov ded wi h a row of g 1 zies.,.;' H I Thefs'aidfbodiesl 19. are individuallyand remov ably supported onani elongate, base"2l'secured to the 'top or thecarri'ag'fC'. {To this endthe're are secured to 'thejbase 21 individual stools 22' havipgup'righti flanges as between which; is con-. fined. a reiractorybedl, the stools being chainbered for p rp ses. presently appearing,

a H Eacli bodyila.isprferablymade up of a series -offltiles.26}bflthe'shape'shown 'in Fig. 4', and the bottomine'mber ofeach body maybe a simple spacerv block 25.. Each'tilehas a nozzle Z'T-and anfoblongfaperture or 'sl'ot' 28. 'W'hen the tiles are assembledin"verticalseries' to make up the body l asshowrr in Fig: 2, the'slots constitute.

what maybe termed a-- tunnel." v a Gas is supplied't'o thenozzles 2'7 by individual nipples 129*Whl8hproject into the receiving end of thenczzles as. is. clearly shown Figs; 2 and 3. The nipples project from a gas pipe 30;-which projects upwardly from an individual stool 22, thel-ower end oithe pipe being indirect com- U munication with a gas. chamber 31 formed in the stool, said chamber being; in direct communication. withfa. maingas chamber 32 formed in the. 7 base 21 as is clearly shownfin'Fig. 5. Gas is de-' livere'd' to, thefmain gas chamber 32'by a main pp ip p If the' gas'fiowing through-the pipes 30 becomes overheated, it will break-down with the libe'raQ tion' of carbonconsequent clogging of. the pipes and the nipples 29. To prevent such overheating, the pipes 30 are water cooled. To this end each pipe is surrounded by a hollow post or water jacket 34 to which water is delivered by a pipe 35 which has its discharge terminal. near the top of the jacket as is shown in Fig. 2and end is closed by being welded to the pipes 30, 35

' i and 39 at a point above the stool 22. It .will be noted that the nipples 29 extend through and project a substantial distance beyond the adjacent side wall of the jacket 34.

In transverse cross section, the jacketis' as wide as the slot 28 in the tile 26 but in transverse length it is the shorter bynthe distance that a nipple 29 projects beyond the wall of the jacket I I as is clearly shown in Fig. 3. Byreason of .this

construction it is a simple matter to position the tiles 26 on the posts as shown in Fig.2. Thus referring to Fig. 3, it will be understood that the space 42 is suificient to' permit the tile to' be moved toward'the right a sufiicient distance to disengage thenipple 29 from the receiving end of the nozzle 27. After a tile'h'as been placed on itspost 34, the space 'or gap 42 will be filled with cement, thus keying the tiles on'the post or jacket 34.

Since each of the bodies 19 is supported ona stool 22 and since these stools are detachably secured to the base 21 and since the burner as a whole may be readily withdrawn from the conduit A, it will'be readily appreciated that it is a simple matter to replace anyparticular'body with a new unit in case necessity demands.

i It is desired that air from the conduit'A shall flow between the bodies 19 in stream-line flow and to this end the individual ,tiles 26 making up the body are of stream-line form as is clearly shown in Fig. 4. It is also desired that the gas shall be discharged from the nozzles 27 in stream-line flow and to this endthe passages which constitute the nozzles are of gradually diverging or stream-line form as is clearly shown in Figs. 2 and 3. From the foregoing description it will be readily appreciated that there will be alternating sheets of air and gas. flowing into the Ifurnace. Ordinarily the air and gas will flow from the passages ;20 and nozzles 27- at equal and relatively low velocities in order that mixing of the air and gas may proceed relatively slowly with the consequent construction of a relatively long flame;

What I claim is: 1. In a gas burner, an elongate base having a gas chamber, a plurality of stools each having a gas chamber in direct communication with the gas chamber in said base, a gas pipe supported.

cent wall of each post, and means associated with said stools and base for supplying cooling fluid to said posts.

2. An article of manufacture for a gas burner comprising an elongate body which at one end and for a substantial portion of its length is circular in cross section and which intermediate its ends on a plane at right angles to the axis of the circular portion is rectangular in cross section andwhich remotefrom'the circular portion of the body is provided with a transversely extending aperture, said circular portion being axially apertured, the two apertures being in communication.

3. In a gas burner, a supporting base, a plurality of elongate bodies supported on said base in upright spaced .relation to form passages through which air may flow, each of said bodies being longitudinally apertured, a hollow post in each of said apertures, a series of nozzles projecting in spaced relation from one longitudinal edge' of each of said bodies, and means housed-by the posts for supplying fuel gas to said'noz'z'les.

; 4.=In a gas burner, the combination of a pluralityof elongate-bodies each having a transverse" aperture therethrough adjacent one end and a longitudinal aperture extending from said transverse aperture to'theother end of the body, said bodies being mounted side by side with their transverse apertures in alinement, and a gas supply pipe extending through the transverse'apertures'an'd cou'pled to the adjacent end of each of the longitudinal apertures for'supplying gasthereto. H V

,5. In a' gas burner, the combinationrof an elongate body having a transverse oblong aperture and a longitudinal aperture extending from said transverseapertureto the other end of the body, and a gas supply pipe extending into said transverse aperture and having a nipple extending into .thefadjacent end of the longitudinal aperture,'the length of the nipple plus the ex ternal diameter of the gas pipe being less than the'major dimension of the oblong aperture.

' 6. Ina gas burner, the combination of an elongate body having a transverse oblong aperture and a longitudi'nal aperture extending from said transverse aperture to the other end of the body, a tubeprojectingintothe oblong aperture and susbtantially filling the latter between its sides, agassupply pipe housed by saidtube, and means-coupling the gas pipe to the adjacent end of the longitudinal aperture.

'7. Ina gas burner, a plurality of elongate bodies arranged in spaced parallel relation to form passages through which air may flow, each of said bodies being longitudinally apertured, a hollow post ineach of said apertures, a series of nozzles projecting in spaced relation from one longitudinal. edge of each of said bodies, and means housed by the posts for supplying fuel to said nozzles.
