GAS BURNER.

This invention relates to gas ,burnershand more particularly to burners especially adapted for use in connection with bakin ovens, although not limited to this specia 5 use. y

An object of the invention is to provide a construction whereby the volume of fuel and air mixture admitted to the severalburner jet openings of the burner maybe indel pendently controlled.

Another object is to provide a burner with control means outside of the oven for regulating the fuel to the several sections of the burner, whereb the heatfrom one. orv more l sect-ions may be varied without disturbing the other sections.

Another object of the invention is to provide a burner construction consistin yof a plurality of substantially concentrlca y arranged tubes leading from a common fuel manifold to separate fuel spaces or burner compartments, the burner having independent-ly adjustable means forregulatmg the amount of fuel admitted to each compart- I ment. v

A further object is to provide a burner which. is. simple and compact in structure and will occupy av minimum amount of space. Certain detailfeatures of the invention herewith shown and described butrnot specifically claimed, are embodied in copending application Serial No. 160,908, filed January 13, 1927. l I.

The above and other objects of the invennection with the description of the embodiments of the invention lllustrated -m the accompanying drawings, in which: 1

Figure 1 is a longitudinal section throughj' 5 of another form of burner.

the

Figure 7 is a cross section taken on line 7-7 of Figure 6.

t' l tion will be more clearly set forth 1n conspec Ivey Figure 8 is a central llongitudinal section` head 11 at 'its inlet end and a head 12 at' rt-ured discs its opposite end. A series of a 13, 14 and 15 are disposed wlthin the tube 10 and form partitions, providing a pluralityv of longitudinally arranged

fuel chambers

16, 17, 18 and 19.

The head 11 is recessed to form a fuelmanifold chamber 21 adapted to receive fuel,l

from a supply pipe (not shown), which may be threaded thereinto. The opposite or inner face of the head is stepped, each said stepped portion having an orifice or fuel.

passage 21 extending therethrough, which communicates with concentrically arranged,

longitudinally extending

tubes

22, 23, 24 and 25', each oa different length. The central tube 25 issupported at one end by the center circular projection on the inner face of head l1, the opposite end being flanged, as at 26, which Bange rests against the head 12. Each of the shorter tubes is 'supported at one end by a portion of the stepped face of the head with its opposite end supported by a partition wall or

disk

13, 14 and 15 re- The partitions serve the dual function of supporting the several tubes, and of dividin the burner into separate chambers. Eac

with a series of discharge' orifices 27; these serve as outlets for the fuel from the several tube is provided adjacent its, end, which is exposed within a chamber, x

tubes direct to the respective surrounding" to direct-the fuel downwardly or away fromthe jet openings 10 so that it must trajvelV a considerable distance through the cham; bers before issuing therefrom. In this form of the invention, the volume of fuel andi air mixture is rojected from the tubes to sgibstantially e base of 'each chamber,

the center of the sleeve. 40 the sleeve 33 co-operate with internal must reverse its direction to reach the burner threaded into the under side of the vouter openings; thus insuring a thorough distribution ofthe volume of the mixture.

Independentcontrol and regulating valves 29 exteriorly threaded and mounted in threaded openings 30 formed in the head 1l, one for each tube and its respective chamber, serve to independently control the volume of fuel and air mixture admittedto the 1U tubes and chambers through the passages 21,

so as to vary the iiame on some sections Without disturbing other sections.

It will be noted in Figure 1, that the burner shown therein is supported -in an l5 opening formed in the wall A of an ovenand that the burner sections and the head 12 are within the oven, whereas the control valves 29 carried by the head 11 are outside of the oven. By arranging the burner in this manner, with the control valves outside of the oven, such valves are accessible at all times, and by manipulating them, the' heat on one or more of the burner sections may be varied without disturbing othersections. This is particularly desirable in the v lindrical casing, within which casing 1s disosed, substantially concentrically, an inner el manifold tube 32. The casing and man,

ifold tube are made in sections united at intervals throughout their length, and between the sections there is provided an exteriorly threaded sleeve or thimble 33, havmg longitudinal slots 33 extending inwardly from each' end to a point adjacent The threads of threads 34 formed" at the end of each section of the casings 3l to unite the casing sections. t will be seen that,-by reason of the provision of slots 33', the volume of fuel and air mixture is enabled to reach and be emitted from the burner jets 38 ad- ]acent the 'meeting ends of each section of the cylindrical casing 31. With such an arrangement of parts, it is possiblevto distrib-` 60 ute thefuel jets or openings 38 throughout the length of the various sections of the rburner. The sleeves serve as partitions, thereby dividing the space between the manlfold and casing into burner chambers 35;

and also function to maintain the manifold tube sections, having abutting ends, properly spaced from the casing'wall.

(was is admitted to the manifold tube 32 from any suitable supply, (not shown) arranged to connect with either end of the pendently operable needle valves 37, screwcasing 37, each valve having a slot 37 in its base for actuating it. The valves function l in precisely the same manner as the valves 29 illustrated in Figures 1 and 3.

Referring to Figures 6 and 7, 40 indicates a pipe into and through which gas is con-V ducted to the burner casing 41,A which burner is, preferably, in the form of a substantially cylindrical tube. A horizontal partition wall 42 having spaced orifices 43 therethrough, divides 4the burner into a Jlower fuel manifold chamber 44 and upper ,burner 'chamber which is sub-divided by ltransverse partitions 45 into burner cham-l bers 46, the said wall extending longitudinally throughout the length of the burner. Needle valves, in' the form of cylindrical plugs 47, exteriorly screw threaded, are adjustably mounted in screw threaded openings 48 formed in the wall of the burner,

and extend across the fuel chamber 44 into the orifices 43 to regulate and control the 'passage of fuel from the fuel chamber to the upper burner chambers.` Each valve member is provided in its base with a slot 47 adapted to receive a screw driver or u similar tool for adjusting it with respect to its seat formed by the orilice 43 in the partition Wall 42. Formed in the burner top are jet openings 48. These openings are disposed at intervals throughout the length of the burner.

Gas from the inlet pipe 40 passes into the fuel manifold 44, through the orifices to the upper burner chambers, from which it is emitted through the openings 48 in the form of a highly intensified flame.

By the Jprovision of adjustable valves 47, whosev conical upper ends are adaptedl to seat in with the orifices 43, it is possible to regulate to a very tine degree the amount of fuel passing to the chambers 46 and openings 48.

In the modification' shown in Figures 8' and 9, 50 indicates the main fuel supply manifold, 51 the burner tube, having jet openings 51 and 52 short tubes or nipples connecting the manifold and the burner tube. The ends of the short tubes are screw threaded intov the manifold and .burner tubes, and each tube has formed in its lower endV a conical seat 53. Threaded through the base of the manifold immediately below each short tube is ascrew threadedsneedle valve 54 of the form employed in connection with the burners of Figures 4 to7. Each tube 52 communicates with one of the

chambers

55, 56, 57 and 58 which are formed in the burner tube bythe provision of transverse partitions 49, arranged at intervals throughout the length of the tube.

In igure 10, the particular form of exteriorly threaded connecting sleeve 33 is illustrated. This sleeve is provided at one riphery with longitudinal portion of its from each end slots 33,' exten mg inwardly `and terminating short of the center of the fuel openings, t e fiame emitted from the ff munication various sections is substantially continuous.

This is particularly ldesirable so that when the issuing gas is ignited at one end of the burner, the iime will flash entirely along the burner. s

In all of the forms hereinbefore described, it will be seen that the mixture of gas and air is fed to each burner chamber having jet openings, from a common source of supply, such as a. manifold, the means of combetween the manifold and the f several chambers being variable. The prefarable form, however, ,is that illustrated in Figures l, 2 and 3, wherein the manifold is at one end of the casing and is connected with the several chambers by va series of concentric tubes extending longitudinally through the burner casing, and each having openings through which the fuel is introduced into each chamber, preferably in a provided in each instance for the purpose of direction away from its jet openings. A separate independently adjustable valve is regulating the amount of fuel mixture supplied to each burner. By the use of these independently controlled valves, it is possible to control the admission of fuel and air i vmixture to each chamber whereby the iame'.

on some sections may be varied without disturbing the flame on other sections.

It is, of course, understoodthat it is withinvthe spirit of the present-invention to make various other changes or modifications in the above described constructions withiny the scope of the appended claims, and alsothat theburners illustrated in the drawings, while 'casing and aving dischar e openings thereparticularly adapted' for use in connection with ovens for baking bread or cake, are not' to be liniited to this specific use, but may be employed in connection with ovens and stoves of various types, or put to any other use for which their particular constructions are adapted.
