Y fThis invention relates to. improvements in gas burners, and more particularly to burners of'the'type employedzi'n 'conjunction With Cooking` stoves'iand ranges, andv it is a primary'object thereof to'improve burners of. `this characterzby'providing features of constructionwhereby improved carburization zof thegas andiair mixtiirefflowing to the burner "-'r'orifices isobtained -andat the same time to secure improved distribution of the carburetted gaseous mixture in order that the latter Lf may 'flow uniformly to and through all of f the orifices provided in the burner, to the end that the operation of the latter vvill be both highly eflicient andreconomical. i

With these and otherobjects lin view which will appear asthe-description proceeds, the

I v invention consists in the novel features of iconstruction, combmations of elements and i arrangementsof parts hereinafter to be fully V des'cribed and' pointedV out in the i appended claimsi In the accompanying drawings:

Figurelis a top plan view of a gas range provided'with the burner mechanism comprising vthe present invention, 7.and

' .Figure 2 is a 'Vertical sectional view taken on the line 2-2 of Figure 1. i

Referring more particularly to the drawings, the numeral 1 Vdesignates the frame structure ofta Cooking range 2. The frame i carries the usual gas supply'manifold 3 which maybe supported in connection with Vthe frame by the use of spaced brackets 4. Carvried by the manifold 3` are control valves 5 of customary construction and which include the usual tapered plugs 6 andv manipulating i handles 7. By means of v'the valves 5 gas flow c from the manifold 3 toaplurality of burnerl f units 8 is controlled.

These burner units each comprise a metallic casting formed to include a centrally hollowed body 9from the upper portion of Which radiates a `plurality of relatively L spaced, horizontally disposed hollow arms 10 having closed outer* ends, the arms being in open communication with the interior of the body 9.v The upp'er surfaces of the arms 10 V are provided Withgasoutletorifices 11.r

l Extending fromthe discharge sides of the valves 5 are pipesf12fwhich lead to each of the burner units 8. These pipes are'supported in relatively spaced relation by the employment of longitudinally extending cross bars 13 Which are stationarily connected With the frame-1. The inner ends 'of 'the pipes 12 are providedwith threaded elbows 14 and the vertically extending branch of each of these' elbows is provided with al gas passage V15terminating in a laterally directed outlet which is formed in a conical stem 16. Threadedly'connected withfthe stem 16 is a gas 'flow orifice cap 17 provided in its upper surface With av restricted Outlet port 18 which may be moved relative to the conical end of the stem 16 in order that the eifective area' of the port 18 maybe varied to control gas flow therethrough, whereby'to `adapt the f burner unit to various gas pressures. I

The lower end of each of the bodies 9 of theburnernnits is provided with a perforated Web 201in which the cap 17 is loosely positioned. In conjunction with each web 20 'there is provided on the lower ends-of each of the bodies 9 an adjustable air shutter 21v which, upon being rotated about the axis of the cap 17 isntilized to control the quantity andr admission of air into the burner'units; Thebu'rner units themselves are supported on the cross'b'ars 13 and carry depending studs'22 formedron the end portions of certain of the arms 10, These studs are positionedwithin openings 23r provided by the cross'bars 13; The studs prevent loss of position of the burner units but permit the latter to be readily removed from the range by merely lifting such units upwardly'thus Supporting the same from the cap 17 and the cross barsi13. This construction permits the airjshutters 21 to be conveniently adjusted t'omeet efficient carburization requireface ofvits upper wall provided axially 'with a; convexl enlargement 24 forming a distributor or deflector. It will be observed that each of these enlargements is located in registration with theorifice or port 18 formed in7 the cap V'17 so; that the gas stream issuing from said port will strike the distributor to break up the gas Stream for the purpose of i produ'cingxa high, degree of turbulence in its prevent channelinglfof the gas Stream, that is/,. the'tendency of the stream to flow more rapidly to. a given area than other essentialareas ofthe burner. v i

- In the usual formvof burner found' connection with gas ranges it is 'customary to cast the burner element with; afl-laterally and longitudinally extending intakea-'branch'which extends to the valves and which isaprovided with' enlarged air introducingV Chambers at theirwouter'ends. This 'usual type of construction. produces to a very large extent channeling of theffuel mixture Stream since :'0! there are-noesharp obstructions-presentr to break up 'the Stream and r'to produce turbulencethereof inits flow toward the orifices of the burnerwelement. .,Moreover, such ordi- 4nary constructions are relatively costly and'l requirev special designs and lpatternsfor the rear burner elements and are quite frequentrly difficult to .remove from. the range for cleaning purposes- It will be observed that v v'in the present invention the pipes 12 extend- .ing from the manifold 3 are formed from standard materials :and are-entirely sepa- V rate. from =the burner unitsl8 and occupy planes below said units so that the gas stream enters said units ina Vertical upward direction.- Since the units. 8 are ofthe same conburner unit to discharge gas xin anupwardly directedstream into said burnereunit, and means carried by the lower portion of said 7burner unit for admitting air into admixture with said gas Stream.
