The present invention relates to improvements in gas burners and relates more particularly to ribbon-type gas burners, i. e., gas burners comprising a slotted-hollow casing or body and a plurality of corrugated-metallic ribbons in the slot of the said casing to provide a plurality of gas-passages for the escape of gas from the interior of the said casing. Usually, the gas referred to -is a combustible mixture of a hydrocarbon gas and air. In gas burners of the type referred to, it is necessary to provide two distinct types of gas-passages when combustible mixtures are employed under appreciable pressures, as is required for most industrial uses as well as for some domestic uses.
Qne of the types of gas-passages above referred to is of a high-velocity type to permit the gas to project itself with sufficient energy to provide a long flame extending to a point remote from the burner. The other type of gas-passage is of low-velocity type to provide suitable relativelyshort pilot-flames immediately adjacent to the burner.
It may here be explained that the gas emerging from the high-velocity gas-passages usually has a velocity greater than the rate of flame-propagation of the gas so that the flame would not continue in the absence of a suitable pilot-flame to support combustion. It, therefore, becomes necessary to support the combustion of the highvelocity gas by relatively-short pilot-flames located close to the burner and provided for by the gas emerging from low-velocity gas-passages.
Inasmuch as the gas emerging from the relatively-low-velocity gas-passages is apt to cause a flash-back into the interior of the casing, due to the fact that the rate of flame-propagation of such gas is apt to exceed the velocity of the said gas as it emerges as described, it is, therefore, necessary in an effective and eflicient gas burner of the type referred to," to so construct and arrange the parts that such flash-backs do not occur.
It is to be borne in mind also that combustible gases used in gas burners vary widely,not only with respect to calorific values but also with respect to their flame-propagation rates.
It is one of the main objects of the present invention, therefore, to provide a simple, reliable 'and efficient construction and arrangement of corrugated ribbons to provide pluralities of both high-velocity gas-passages and relatively-lowvelocity gas-passages.
, Another and more specific object of the present invention is to provide a superior ribbon-type gas burner which will reliably provide both highvelocity and relatively-low-veloeity gas-passages without setting up distortion-stresses of a hamfulnatm'ewhenthe gasburnerbecomeshighly heatedinuse.
.i. e., high-velocity, low-velocity and mediumvelocity or intermediate-velocity. gas-passag with the above and other objects in view, as will appear to those skilled in the art from the prwent disclosure, this invention includes all fea tures in the said disclosure which are novel over the prior art and not claimed by me in my copending application SerialNo. 69,275 filed January 5, 1949.

10 is a broken perspective view of a. modifled form of minor ribbon.
The gas burnerof Figs. 1 to 5 inclusive The gas burner illustrated in the figures above erence character II, and having a longitudinal rib l2 upstanding from its upper surface. In the instance shown, the casing ll is provided at its respective opposite ends with gas-tight end walls Ila and ltb. The end wall l3b of the casing is provided with internal threads ll adapted to receive a supply-pipe of any suitable nature (not shown) to supply a suitable gaseous combustible mixture to the interior of the casing l I.
The upstanding rib l2 of the casing II is formed with a longitudinal slot l5 extending from the interior to the exterior of the said casing and terminating short of the respective ends of the latter as is shown in Fig. 1.
Arranged in face-to-tace, relationship in the slot lb of thecasing is a group of transversely corrugated ribbons of stainless steel or other suitable material and including three minor ribbons lta, lib and I60 and four major ribbons lla, l'lb, I and I111.
The term minor" ribbons has been adopted for convenience of description, since each of the said ribbons is provided with minor corrugations it, which have a shorter or minor distance between their respective peaks or apices (in a direction lengthwise of a given ribbon) than do the hereinafterdescribed corrugations of the major ribbons lla, l'lb, lie and lid.
The term major ribbons has been applied to the ribbons l'la, llb, lie and lid also for convenience of description, inasmuch as the said ribbons are formed with major corrugations l9 which have substantially-flat peaks or apices and emerging from the said gas-passages 23 will project a greater degree away from the casing or body ll than will the gas emerging from the which have a greater or major distance between them as compared to the aforesaid minor corrugations.
The minor ribbon lSa is located in contact with the adjacent wall of the slot l5 and in contact with the adjacent major ribbon Ila, which latter is in turn in contact with the major ribbon I111. The major corrugations IQ of the major ribbons l'la and I'll) are arranged in opposition as shown.
Flanking the major ribbon l'lb is the minor ribbon lib. Interposed between the minor ribbons ltb and l6c are the major ribbons I10 and lid, which latter have their corrugations l9 arranged in opposition. The minor ribbon I60 thus is in contact or in substantial contact with the adjacent wall of the slot IS.
The ribbons above referred to may be retained in place in the slot IS in any suitable manner such, for instance, as by transverse pins 20 indicated in Figs. 1 and 2. The arrangement of major and minor ribbons above described, results in the formation of a plurality of what may be aptly termed low-velocity gas-passages 2|, a pin gas-passages 2| and 22.
Thus, the gas burner illustrated in Figs. 1 to 5 inclusive, will produce three different heights of flames with the long flames provided by the highvelocity gas-passages 23 being maintained by the flames provided by both the low-velocity gaspassages 2| and the intermediate-velocity gaspassages 22 and with the flames from the said intermediate-velocity gas-passages 22 in turn being maintained by the flames provided by the low-velocity gas-passages 2l.
From the foregoing, it will be seen that in a relative sense, both the gas-passages 2| and 22 are low-velocity as compared to the gas-passages 23, while the gas-passages 22 are high-velocity as compared to the gas-passages 2|.
The structure of Fig. 6
In Fig. 6 is shown a casing or body generally designated by the reference character 24 and basically corresponding to the casing or body ll before described. Similar to the body ll, the body 24 has an upstanding-longitudinal rib 25 formed with a slot 26 corresponding to the slot I5 before described save that it is slightly narrower than the latter.
Mounted in the slot 26 is a group of transversely-corrugated ribbons comprising a single minor ribbon lid and four major ribbons lle, Hi, Hg and "it.
The major ribbons lle, I1 I19 and lift correspond to the major ribbons previously described and are provided with transverse major corrugations 21.
The minor ribbon lid corresponds to the minor ribbons previously described and is formed with transverse minor corrugations 28.
The major ribbon He is arranged in contact with the adjacent wall of the slot 26 in the rib terialiy slowed down as compared to the gas 25 and also in contact with the companion major ribbon I11. I
The major ribbon llh is arranged in contact with the adjacent wall of the slot 26 and also in contact with its companion major ribbon Hg. The minorribbon lBd is interposed directly between the major ribbons l1! and Hg.
The arrangement of the minor ribbon lid and the major ribbons lle, l'lf, I10 and "I2 is such that there is formed a plurality of low-ve ocity gas-passages 29, a plurality of intermediatevelocity gas-passages 20 and a plurality of highvelocity gas-passages II.
The structure illustrated in Fig. 6 will thus provide three difl'erent heights of flames in a manner generally similar to the flames described in connection with the discussion of the showing of Figs. 1 to 5 inclusive.
The structure of Fig. 7
plurality of relatively-high-velocity gas-passages and a plurality of relatively-lower-velocity gaspassages.
The gas-burner now being described includes,
like the preceding forms, a suitable casing or body generally designated by the reference character 32 basically similar to the casings II and 24 before described, save that its rib 35 is provided with a longitudinal slot 34 having a greater width than the slots of either of the previously described gas-burners. I Mounted in the slot 34 is a group of transversely-corrugated ribbons comprising four minor ribbons I6e, I61, I69 and Ilh and five major ribbons Ili, Ili, Ilk, Illand Ilm.
The minor ribbons I6e, I6 I69 and I6h generally correspond to the minor ribbons previously described and are provided with transverse minor corugations 35.
The major ribbons Ili, Ilj, Ilk, Ill and Ilm also correspond to the major ribbons previously described and are provided with transverse major corrugations 36. y
The minor ribbon I6e is arranged in contact with the adjacent wall of the slot 34 and with the adjacent major ribbon Ili. Placed in contact and in opposition to the major ribbon Ili is the major ribbon I17. Interposed' between the major ribbons I19 and Illc is the minor ribbon I6f before described. The minor ribbon I6g is, in turn, located between the major ribbons Ilk and Ill.
Located against and in opposition to the major ribbon Ill is the major ribbon Ilm. Interposed between the major ribbon Ilm and the adjacent wall of the slot 34 is the minor ribbon I6h previously referred to.
Theminor ribbons I6e, I6f, I69 and I6h and the major ribbons I11, I17, Illc, Ill and Ilm are so arranged in the slot 34 as to provide a plurality of low-velocity gas-passages 31', a plurality of intermediate velocity gas passages 36 and a plurality of high-velocity gas-passages 39.
Like the gas burners previously described, the structure illustrated in Fig. '7 will provide three diflerent heights of flame, in a manner generally similar to the flames described in connection with the discussion of Figs. 1 to 6 inclusive, save that the flame-pattern is slightly different.
The structure of Fig. 8
In Fig. 8 is shown a casing generally designated by the reference character 40 and like the preceding forms, having a longitudinal rib 4I provided with a slot 42. The features 40, M and 42 just described correspond in substance to the similar features previously described.
Mounted in the slot 42, is a group of transversely-corrugated ribbons comprising four minor ribbons I6i,- I67, I6k and I61 and a similar number of major ribbons Iln, Ilo, Ilp and Ilq.
The minor ribbons I62, I67, I6lc and I6l-are provided with transverse minor corrugations 43, while the major ribbons Iln, Ilo, Ilp and Ilq are formed with transverse major corrugations 44.
The minor ribbons and major ribbons just above referred to correspond in substance to the similar ribbons previously described. v
The minor ribbons I61, I61, I 51; and I61 and the major ribbons Iln, Ilo, Ilp and Ilq are intermingled to provide a plurality of low-velocity gas-passages 45, a plurality of intermediatevelocity gas-passages 46 and a plurality of highvelocity gas-passages 41. which latter form a single row located substantially centrally of the structure. v
Here, again, the structure now being described wfll provide flames of three diflerent characteristics, in a manner similar to the flames produced by the structures previously described.
The structure ofFig. 9
Fig. 9 illustrates a slight variation in the arrangement of major and minor ribbons and includes, like the preceding forms, a casing, which in this instance is generally designated by the reference character 46, which has an upstanding longitudinal rib 49. The rib 49 is formed with a longitudinal slot 50 similar to the slots I5, 26, 34 and 42 previously described.
Secured in any suitable manner in the slot 56 is a group of transversely-corrugated ribbons comprising three minor ribbons I6m, I6n and I60, together with four major ribbons Ilr, Ils, Ilt and Ilu. v
The minor ribbons and the major ribbons just above described, are respectively provided with minor corrugations 5I and major corrugations 52. The arrangement of the minor ribbons and major ribbons above described, results in the provision of a plurality of low-velocity gaspassages 53, a plurality of intermediate-velocity gas-passages and a plurality of high-velocity gas-passages The minor ribbons and the major ribbons in the structure of Fig. 9 correspond in number and transverse location to the similar ribbons in the structure of Figs. 1 to 5 inclusive. The longitudinal disposition of the various ribbons is, however, difierent.
It will be noted by reference to Fig. 9 that the pair of opposed major ribbons I11 and Ils is displaced longitudinally of the structure with respect to the opposed pair of major ribbons I lt and Ilu so that one series of high-velocity gas-passages 55 is staggered with respect to the other series of similar gas-passages.
The ribbon of Fig. 10
In Fig. 10 is shown a transversely-corrugated minor ribbon generally designated by the reference character 56 and having transverse corrugations 51.
The corrugations 51 instead of extending at a substantial right angle with respect to the longitudinal edges of the ribbon as is the case in the preceding structures, extend diagonally in this instance.
The minor ribbon 56 may be substituted in place of the previously-described minor ribbons and when so utilized, will provide gas passages of a somewhat longer extent which may be preferable-under some operating conditions.
The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore to be considered in all re- 'said casing; the said group of ribbons including at least one ribbon having a continuous series of major corrugations free of minor corrugations between them and at least one ribbon having a continuous series oi minor corrugations free or major corrugations between them; the said major corrugations .having substantially flat apices and being of lesser number per unit or ribbon length as compared to the said minor corrugations which are greater in number for the same unit of ribbon length; the two said ribbons being arranged in face-to-face engagement in the slot of the said casing to provide directly between them a plurality of relatively-large high-velocity gas-passages and a plurality of relatively-small low-velocity gas-passages.
