This invention. relates to improvements in enjc'ejto an improved form of Bunsen burner adapted tov be readily'connected to or disconnected from a gas supply pipe or the like.

In many gas burner installations; as for example, in gas broilers; water heaters, etc, it. is frequently necessary to remove the burners for cleaning, adjustments or repairs. The devices in use prior to this invention have been objectionable because" such burners have riotbee'ncapable of convenient removaland replacement; Usually they have 0 i11 eluded vthreaded have required manipulation, and in many instances the burners have requi-redtilting into difierent planes during'j insertion or removal; These and other objections are overcome by the present inventiom which in its broader aspects contemplates a gas'burner connection of such a character fth'atgthe burner may be removed fronror applied to a gas nozzle bya directlater'al movement relaf tive to said nozzle. f V V lMore specifically, the invention 'c'ofrnpre; hends the provision of a gas burnerfof the Bunsen type havingja gas tube and a gas nozzle. so constructed andarranged as to per- Init relative movement in a directiont an verse to the. axis ofthe gas nozzle. c I 1 Another feature of. he invention is" the provision. of. such a device with improved and, simplified. means for holding the burner and: nozzle against accidental displacement such means being preferably in orporated 'with a shutter valve.

Another feature. of the invention resides the provision of an improved shutter valve for controlling admission of primary'airjto theburner. f

Other features and. advantages .wjflf be apparent from the following description,

reierence being had to the. ccompa ying drawings, wherein'ione embodiment of the invention is shown. by way oi illustration,

' In the shown as apgned to a gas broiler; but if is not restric te v tofsuch use it is equally adaptable-for use in' 'other' environments: Such an installation my comprise a broil-ing oven 10 of any ordinary or preferred design,

and equipped with Bunsen ,burners ,11, here shown astwo in nixmber, (m at each side of;

the o'venq' The two burnersll arealike'; and therefore'a detailed description" of one will sufiice to; conveyafull understandingfofi'the invention. c' a Each burner 11' comprises a horizontal member or burner proper l25 proviided with a plurality of'su'itable flameports 13, we

erably di're'ctfed toward the interior 0; the

broiler. The member '12 is hollow. "and 'e'xtendsthrough the front; wall of the oven 10, beingxremovably mounted, and having its inner end supgortedin such position'by I,

meansof a lug 1 see'. Figure; 2; in engage meat with a suitable support'notishown. mixingi'tube" 15 communicates with thememe ber"12 and may preferably beffior'med integral therewith extending' downwardly outside of the oven and toward a gas supply pipeorm nimdie The mixing. tube 15 is preferably tapered as sh'qwn', and adjacent its extremity, the walls of said tube flare outwardly to form an enlarg ed mouth 17 havingl'a transverse web 18- at its outer end. f Ex ndi g. u rd ro gh a li el orifice 19. in the web 1.8i'i'sj a gas nozzle 26 Whlfil'i terminates; within L the mouth 1? and if ffit fleb d to the gas. upp y? wa he K I p v drawings, the invention has been mary air to the mixingtube, the web 18 is provided with a plurality of openings 22, here shown as two in number, of general sector shape, and disposed at opposite sides of the orifice 19. The mouth of the mixing tube is further provided with a shutter valve. 23 for controlling the amount of air passing through the openings 22, said valve being preferably cup-shaped and rotatably mounted in close engagement with the web 18 and outer wall of the mouth 17. The web 24 of the valve 23 is similar to the web 18, being provided with a central orifice 25 through which the nozzle 20 is adaptedto extend and with a pair of apertures 26 for selective registration with the openings 22.

It will be evident that, with a construction as thus far described,"the burner could only be removed from operativeposition in the broiler by lifting the burner with its shutter valve until it has cleared the end of the 'nozzle20 and then moving itlaterally, and the same operations are necessary, in reverse order, to replace the burner. limitation has constituted a serious clefectin therart, which the present invention overcomes. j v

To'this end, the web 18 is formed with. a slot 27 which extends radially from the central orifice 19 in the same direction as the burner member 12,. and continues into the wall of the mouth portion 17 to a point above the end of the nozzle 20. Similarly, the shutter valve 23 is formed with a slot'28 extending radially from the orifice 25 and through its side wall 29. In order to reinforce the web 24 of the valve, the marginal edges of the slot 28 and orifice25. may be thickened as at 80, which is additionally advantageous in that it provides a greater surface for the web against the side of the nozzle. It will be seen that with the mixing tube 13 and shut ter valve 22 constructed as thus described, the gas burner 11 can be set in place, as shown in Figures 1' and 2, with a direct lateral movement, or a movement in a direction transverse to the axis of the nozzle, and

without. changing the plane of the burner.

When first assembling the parts, the valve is positioned on the end of the mixing tube with the slots 27 and 28 in registration, whereupon the horizontalmember- 12 isinserted in the wall of the oven 10 and pushed rearwardly until the nozzle arrests further movement by contact with the edge of the, orifices 19 and 25 as shown in Figure 6.

This

The valve may then be rotated to a position such as shown in Figure 5 or any intermediate position dependent upon the amount of air desired in the mixing tube. It is to be noted that when't-he valve is thus turned, it positively prevents accidental displacement of the burner relative to the nozzle by virtue of the nozzle being engaged at opposite sides by the edges of the respective orifices 19 and When it is desired to remove a burner from the broiler, the valve 23 need only be rotated until its slot 28 overlies the slot 27 inthe end of the mixing tube, whereupon the burner and its associated parts may be withdrawn by a direct lateral movement, as indicated dotted linesin Figure2.

From the foregoing it will be obvious v a substantial improvement hasbeen made in the gas burner art. In ltSbIYQLdBI aspects,

maybe applied to a wide variety of gasheaters without departing from the scope of the nventlon or sacr ficing its ch ef advantages.

Havingthus de'scribed my invention, what I claim is 1. In a Bunsen burner,a'mixing tube, a

gas nozzle extending into the endfof said tube, one side of said tube being slotted at its extremity to provide clearance for said nozzle, and locking means attached to the mixing;tube,1 said locking means being formed. so as to selectively obstruct or'uncover the slot in the mixing tube. 2. In a Bunsen burner, a mil ing tube having an openmouth, the wall of the tube being slotted at one side of said mouth to permit lateralpassage of a gas nozzle which extends intosaid'mouth, and ashutter valve rotatable on the mouth andabout the gas nozzle, said shutter valve having a slot adapted for registration with the slot in the tube wall, such construction preventing relative" lateral :movement between the nozzle and the tube when said slots are out of registration.

y 3. A Bunsen burnerprovided with a mix ing tube having a web at its mouth formed with an air inlet, a shutter valve rotatably mounted upon said mouth and being formed withan aperture adapted toregister with said air inletJsaid tube and shutter valve being formed each witha slot adapted'to be brought into or out of registration with each other; whereby the burner may be applied to or removed from a gas nozzle by a relatively lateral movement, and whereby the shutter valve may be rotated to regulate the supply of air to the tubeand also to lock the tube in place.

bination, a gas burner having a mixing tube formed with a Web at its mouth, said Web being apertured to provide an air inlet, a gas nozzle extending into the end of said mixing tube, and a shutter valve rotatable about the nozzle and on the end of said tube,

the web of the tube and the shutter valve of the part.

In testimony whereof, I
